https://www.cityreal.lv/acyclovir-ointment-price/ case and death counts by country, and a global buy acyclovir online canada map showing which countries have confirmed cases and deaths. The data are drawn from the Johns buy acyclovir online canada Hopkins University (JHU) Coronavirus Resource Center’s COVID-19 Map and the World Health Organization’s (WHO) Coronavirus Disease (COVID-2019) situation reports.This tracker will be updated regularly, as new data are released.Related Content. About COVID-19 CoronavirusIn late 2019, a new coronavirus emerged in central China to cause disease in humans. Cases of buy acyclovir online canada this disease, known as COVID-19, have since been reported across around the globe. On January 30, 2020, the World Health Organization (WHO) declared the virus represents a public health emergency of international concern, and on January 31, 2020, the U.S.

Department of Health and Human Services declared it to be a health emergency for the United States.With schools nationwide preparing for fall and the buy acyclovir online canada federal government encouraging in-person classes, key concerns for school officials, teachers and parents include the risks that coronavirus poses to children and their role in transmission of the disease.A new KFF brief examines the latest available data and evidence about the issues around COVID-19 and children and what they suggest about the risks posed for reopening classrooms. The review concludes that while children are much less likely than adults to become severely ill, they can buy acyclovir online canada transmit the virus. Key findings include:Disease severity is significantly less in children, though rarely some do get very sick. Children under age 18 account for 22% of the population but account for just 7% of the more than 4 million COVID-19 cases and less than 1% of deaths.The evidence is mixed about whether children are less likely than adults to become infected buy acyclovir online canada when exposed. While one prominent study estimates children and teenagers are half as likely as adults over age 20 to catch the virus, other studies find children and adults are about equally likely to have antibodies that develop after a COVID-19 infection.While children do transmit to others, more evidence is needed on the frequency and extent of that transmission.

A number of studies find children are less likely than adults to be the source of infections in households and other settings, though this could occur because of differences in testing, the severity of the disease, and the impact buy acyclovir online canada of earlier school closures.Most countries that have reopened schools have not experienced outbreaks, but almost all had significantly lower rates of community transmission. Some countries, including Canada, Chile, France, and Israel did experience school-based outbreaks, sometimes significant ones, that required schools to close a second time.The analysis concludes that there is a risk of spread associated with reopening schools, particularly in states and communities where there is already widespread community transmission, that should be weighed carefully against the benefits of in-person education..

Acyclovir cream generic

Patients Figure 1 acyclovir cream generic. Figure 1. Enrollment and acyclovir cream generic Randomization. Of the 1107 patients who were assessed for eligibility, 1063 underwent randomization. 541 were assigned to the acyclovir cream generic remdesivir group and 522 to the placebo group (Figure 1).

Of those assigned to receive remdesivir, 531 patients (98.2%) received the treatment as assigned. Forty-nine patients had remdesivir treatment discontinued before day 10 because of an adverse event or a serious adverse event other than acyclovir cream generic death (36 patients) or because the patient withdrew consent (13). Of those assigned to receive placebo, 518 patients (99.2%) received placebo as assigned. Fifty-three patients discontinued placebo before day 10 because of an adverse event or a serious adverse event other than death (36 patients), because the patient withdrew consent (15), or because the patient was found to be ineligible for trial enrollment (2). As of April 28, 2020, a total acyclovir cream generic of 391 patients in the remdesivir group and 340 in the placebo group had completed the trial through day 29, recovered, or died.

Eight patients who received remdesivir and 9 who received placebo terminated their participation in the trial before day 29. There were 132 patients in the remdesivir group and 169 in the acyclovir cream generic placebo group who had not recovered and had not completed the day 29 follow-up visit. The analysis population included 1059 patients for whom we have at least some postbaseline data available (538 in the remdesivir group and 521 in the placebo group). Four of the 1063 patients were not acyclovir cream generic included in the primary analysis because no postbaseline data were available at the time of the database freeze. Table 1.

Table 1 acyclovir cream generic. Demographic and Clinical Characteristics at Baseline. The mean age of patients was 58.9 years, and 64.3% were male (Table 1). On the basis of the evolving epidemiology of Covid-19 during the trial, 79.8% acyclovir cream generic of patients were enrolled at sites in North America, 15.3% in Europe, and 4.9% in Asia (Table S1). Overall, 53.2% of the patients were white, 20.6% were black, 12.6% were Asian, and 13.6% were designated as other or not reported.

249 (23.4%) acyclovir cream generic were Hispanic or Latino. Most patients had either one (27.0%) or two or more (52.1%) of the prespecified coexisting conditions at enrollment, most commonly hypertension (49.6%), obesity (37.0%), and type 2 diabetes mellitus (29.7%). The median number of days acyclovir cream generic between symptom onset and randomization was 9 (interquartile range, 6 to 12). Nine hundred forty-three (88.7%) patients had severe disease at enrollment as defined in the Supplementary Appendix. 272 (25.6%) patients met category 7 criteria on the ordinal scale, 197 (18.5%) category 6, 421 acyclovir cream generic (39.6%) category 5, and 127 (11.9%) category 4.

There were 46 (4.3%) patients who had missing ordinal scale data at enrollment. No substantial imbalances in baseline characteristics were observed between the remdesivir group and the placebo group. Primary Outcome acyclovir cream generic Figure 2. Figure 2. Kaplan–Meier Estimates acyclovir cream generic of Cumulative Recoveries.

Cumulative recovery estimates are shown in the overall population (Panel A), in patients with a baseline score of 4 on the ordinal scale (not receiving oxygen. Panel B), in those acyclovir cream generic with a baseline score of 5 (receiving oxygen. Panel C), in those with a baseline score of 6 (receiving high-flow oxygen or noninvasive mechanical ventilation. Panel D), and in those with a baseline score of 7 (receiving mechanical ventilation acyclovir cream generic or ECMO. Panel E).

Time to Recovery According to Subgroup acyclovir cream generic. The widths of the confidence intervals have not been adjusted for multiplicity and therefore cannot be used to infer treatment effects. Race and acyclovir cream generic ethnic group were reported by the patients. Patients in the remdesivir group had a shorter time to recovery than patients in the placebo group (median, 11 days, as compared with 15 days. Rate ratio for recovery, 1.32.

95% confidence interval [CI], acyclovir cream generic 1.12 to 1.55. P<0.001. 1059 patients (Figure acyclovir cream generic 2 and Table 2). Among patients with a baseline ordinal score of 5 (421 patients), the rate ratio for recovery was 1.47 (95% CI, 1.17 to 1.84). Among patients with a baseline score of 4 (127 patients) and those with a baseline score of 6 (197 acyclovir cream generic patients), the rate ratio estimates for recovery were 1.38 (95% CI, 0.94 to 2.03) and 1.20 (95% CI, 0.79 to 1.81), respectively.

For those receiving mechanical ventilation or ECMO at enrollment (baseline ordinal scores of 7. 272 patients), the rate ratio for recovery was 0.95 acyclovir cream generic (95% CI, 0.64 to 1.42). A test of interaction of treatment with baseline score on the ordinal scale was not significant. An analysis adjusting for baseline ordinal score as a stratification variable was conducted to evaluate the overall effect (of the percentage of patients in each ordinal score category at baseline) on the primary outcome. This adjusted analysis produced acyclovir cream generic a similar treatment-effect estimate (rate ratio for recovery, 1.31.

95% CI, 1.12 to 1.54. 1017 patients) acyclovir cream generic. Table S2 in the Supplementary Appendix shows results according to the baseline severity stratum of mild-to-moderate as compared with severe. Patients who acyclovir cream generic underwent randomization during the first 10 days after the onset of symptoms had a rate ratio for recovery of 1.28 (95% CI, 1.05 to 1.57. 664 patients), whereas patients who underwent randomization more than 10 days after the onset of symptoms had a rate ratio for recovery of 1.38 (95% CI, 1.05 to 1.81.

380 patients) (Figure 3) acyclovir cream generic. Key Secondary Outcome The odds of improvement in the ordinal scale score were higher in the remdesivir group, as determined by a proportional odds model at the day 15 visit, than in the placebo group (odds ratio for improvement, 1.50. 95% CI, 1.18 to 1.91. P=0.001. 844 patients) (Table 2 and Fig.

S5). Mortality was numerically lower in the remdesivir group than in the placebo group, but the difference was not significant (hazard ratio for death, 0.70. 95% CI, 0.47 to 1.04. 1059 patients). The Kaplan–Meier estimates of mortality by 14 days were 7.1% and 11.9% in the remdesivir and placebo groups, respectively (Table 2).

The Kaplan–Meier estimates of mortality by 28 days are not reported in this preliminary analysis, given the large number of patients that had yet to complete day 29 visits. An analysis with adjustment for baseline ordinal score as a stratification variable showed a hazard ratio for death of 0.74 (95% CI, 0.50 to 1.10). Safety Outcomes Serious adverse events occurred in 114 patients (21.1%) in the remdesivir group and 141 patients (27.0%) in the placebo group (Table S3). 4 events (2 in each group) were judged by site investigators to be related to remdesivir or placebo. There were 28 serious respiratory failure adverse events in the remdesivir group (5.2% of patients) and 42 in the placebo group (8.0% of patients).

Acute respiratory failure, hypotension, viral pneumonia, and acute kidney injury were slightly more common among patients in the placebo group. No deaths were considered to be related to treatment assignment, as judged by the site investigators. Grade 3 or 4 adverse events occurred in 156 patients (28.8%) in the remdesivir group and in 172 in the placebo group (33.0%) (Table S4). The most common adverse events in the remdesivir group were anemia or decreased hemoglobin (43 events [7.9%], as compared with 47 [9.0%] in the placebo group). Acute kidney injury, decreased estimated glomerular filtration rate or creatinine clearance, or increased blood creatinine (40 events [7.4%], as compared with 38 [7.3%]).

Pyrexia (27 events [5.0%], as compared with 17 [3.3%]). Hyperglycemia or increased blood glucose level (22 events [4.1%], as compared with 17 [3.3%]). And increased aminotransferase levels including alanine aminotransferase, aspartate aminotransferase, or both (22 events [4.1%], as compared with 31 [5.9%]). Otherwise, the incidence of adverse events was not found to be significantly different between the remdesivir group and the placebo group.Trial Population Table 1. Table 1.

Characteristics of the Participants in the mRNA-1273 Trial at Enrollment. The 45 enrolled participants received their first vaccination between March 16 and April 14, 2020 (Fig. S1). Three participants did not receive the second vaccination, including one in the 25-μg group who had urticaria on both legs, with onset 5 days after the first vaccination, and two (one in the 25-μg group and one in the 250-μg group) who missed the second vaccination window owing to isolation for suspected Covid-19 while the test results, ultimately negative, were pending. All continued to attend scheduled trial visits.

The demographic characteristics of participants at enrollment are provided in Table 1. Vaccine Safety No serious adverse events were noted, and no prespecified trial halting rules were met. As noted above, one participant in the 25-μg group was withdrawn because of an unsolicited adverse event, transient urticaria, judged to be related to the first vaccination. Figure 1. Figure 1.

Systemic and Local Adverse Events. The severity of solicited adverse events was graded as mild, moderate, or severe (see Table S1).After the first vaccination, solicited systemic adverse events were reported by 5 participants (33%) in the 25-μg group, 10 (67%) in the 100-μg group, and 8 (53%) in the 250-μg group. All were mild or moderate in severity (Figure 1 and Table S2). Solicited systemic adverse events were more common after the second vaccination and occurred in 7 of 13 participants (54%) in the 25-μg group, all 15 in the 100-μg group, and all 14 in the 250-μg group, with 3 of those participants (21%) reporting one or more severe events. None of the participants had fever after the first vaccination.

After the second vaccination, no participants in the 25-μg group, 6 (40%) in the 100-μg group, and 8 (57%) in the 250-μg group reported fever. One of the events (maximum temperature, 39.6°C) in the 250-μg group was graded severe. (Additional details regarding adverse events for that participant are provided in the Supplementary Appendix.) Local adverse events, when present, were nearly all mild or moderate, and pain at the injection site was common. Across both vaccinations, solicited systemic and local adverse events that occurred in more than half the participants included fatigue, chills, headache, myalgia, and pain at the injection site. Evaluation of safety clinical laboratory values of grade 2 or higher and unsolicited adverse events revealed no patterns of concern (Supplementary Appendix and Table S3).

SARS-CoV-2 Binding Antibody Responses Table 2. Table 2. Geometric Mean Humoral Immunogenicity Assay Responses to mRNA-1273 in Participants and in Convalescent Serum Specimens. Figure 2. Figure 2.

SARS-CoV-2 Antibody and Neutralization Responses. Shown are geometric mean reciprocal end-point enzyme-linked immunosorbent assay (ELISA) IgG titers to S-2P (Panel A) and receptor-binding domain (Panel B), PsVNA ID50 responses (Panel C), and live virus PRNT80 responses (Panel D). In Panel A and Panel B, boxes and horizontal bars denote interquartile range (IQR) and median area under the curve (AUC), respectively. Whisker endpoints are equal to the maximum and minimum values below or above the median ±1.5 times the IQR. The convalescent serum panel includes specimens from 41 participants.

Red dots indicate the 3 specimens that were also tested in the PRNT assay. The other 38 specimens were used to calculate summary statistics for the box plot in the convalescent serum panel. In Panel C, boxes and horizontal bars denote IQR and median ID50, respectively. Whisker end points are equal to the maximum and minimum values below or above the median ±1.5 times the IQR. In the convalescent serum panel, red dots indicate the 3 specimens that were also tested in the PRNT assay.

The other 38 specimens were used to calculate summary statistics for the box plot in the convalescent panel. In Panel D, boxes and horizontal bars denote IQR and median PRNT80, respectively. Whisker end points are equal to the maximum and minimum values below or above the median ±1.5 times the IQR. The three convalescent serum specimens were also tested in ELISA and PsVNA assays. Because of the time-intensive nature of the PRNT assay, for this preliminary report, PRNT results were available only for the 25-μg and 100-μg dose groups.Binding antibody IgG geometric mean titers (GMTs) to S-2P increased rapidly after the first vaccination, with seroconversion in all participants by day 15 (Table 2 and Figure 2A).

Dose-dependent responses to the first and second vaccinations were evident. Receptor-binding domain–specific antibody responses were similar in pattern and magnitude (Figure 2B). For both assays, the median magnitude of antibody responses after the first vaccination in the 100-μg and 250-μg dose groups was similar to the median magnitude in convalescent serum specimens, and in all dose groups the median magnitude after the second vaccination was in the upper quartile of values in the convalescent serum specimens. The S-2P ELISA GMTs at day 57 (299,751 [95% confidence interval {CI}, 206,071 to 436,020] in the 25-μg group, 782,719 [95% CI, 619,310 to 989,244] in the 100-μg group, and 1,192,154 [95% CI, 924,878 to 1,536,669] in the 250-μg group) exceeded that in the convalescent serum specimens (142,140 [95% CI, 81,543 to 247,768]). SARS-CoV-2 Neutralization Responses No participant had detectable PsVNA responses before vaccination.

After the first vaccination, PsVNA responses were detected in less than half the participants, and a dose effect was seen (50% inhibitory dilution [ID50]. Figure 2C, Fig. S8, and Table 2. 80% inhibitory dilution [ID80]. Fig.

S2 and Table S6). However, after the second vaccination, PsVNA responses were identified in serum samples from all participants. The lowest responses were in the 25-μg dose group, with a geometric mean ID50 of 112.3 (95% CI, 71.2 to 177.1) at day 43. The higher responses in the 100-μg and 250-μg groups were similar in magnitude (geometric mean ID50, 343.8 [95% CI, 261.2 to 452.7] and 332.2 [95% CI, 266.3 to 414.5], respectively, at day 43). These responses were similar to values in the upper half of the distribution of values for convalescent serum specimens.

Before vaccination, no participant had detectable 80% live-virus neutralization at the highest serum concentration tested (1:8 dilution) in the PRNT assay. At day 43, wild-type virus–neutralizing activity capable of reducing SARS-CoV-2 infectivity by 80% or more (PRNT80) was detected in all participants, with geometric mean PRNT80 responses of 339.7 (95% CI, 184.0 to 627.1) in the 25-μg group and 654.3 (95% CI, 460.1 to 930.5) in the 100-μg group (Figure 2D). Neutralizing PRNT80 average responses were generally at or above the values of the three convalescent serum specimens tested in this assay. Good agreement was noted within and between the values from binding assays for S-2P and receptor-binding domain and neutralizing activity measured by PsVNA and PRNT (Figs. S3 through S7), which provides orthogonal support for each assay in characterizing the humoral response induced by mRNA-1273.

SARS-CoV-2 T-Cell Responses The 25-μg and 100-μg doses elicited CD4 T-cell responses (Figs. S9 and S10) that on stimulation by S-specific peptide pools were strongly biased toward expression of Th1 cytokines (tumor necrosis factor α >. Interleukin 2 >. Interferon γ), with minimal type 2 helper T-cell (Th2) cytokine expression (interleukin 4 and interleukin 13). CD8 T-cell responses to S-2P were detected at low levels after the second vaccination in the 100-μg dose group (Fig.

S11).Trial Design and Oversight The RECOVERY trial was designed to evaluate the effects of potential treatments in patients hospitalized with Covid-19 at 176 National Health Service organizations in the United Kingdom and was supported by the National Institute for Health Research Clinical Research Network. (Details regarding this trial are provided in the Supplementary Appendix, available with the full text of this article at NEJM.org.) The trial is being coordinated by the Nuffield Department of Population Health at the University of Oxford, the trial sponsor. Although the randomization of patients to receive dexamethasone, hydroxychloroquine, or lopinavir–ritonavir has now been stopped, the trial continues randomization to groups receiving azithromycin, tocilizumab, or convalescent plasma. Hospitalized patients were eligible for the trial if they had clinically suspected or laboratory-confirmed SARS-CoV-2 infection and no medical history that might, in the opinion of the attending clinician, put patients at substantial risk if they were to participate in the trial. Initially, recruitment was limited to patients who were at least 18 years of age, but the age limit was removed starting on May 9, 2020.

Pregnant or breast-feeding women were eligible. Written informed consent was obtained from all the patients or from a legal representative if they were unable to provide consent. The trial was conducted in accordance with the principles of the Good Clinical Practice guidelines of the International Conference on Harmonisation and was approved by the U.K. Medicines and Healthcare Products Regulatory Agency and the Cambridge East Research Ethics Committee. The protocol with its statistical analysis plan is available at NEJM.org and on the trial website at www.recoverytrial.net.

The initial version of the manuscript was drafted by the first and last authors, developed by the writing committee, and approved by all members of the trial steering committee. The funders had no role in the analysis of the data, in the preparation or approval of the manuscript, or in the decision to submit the manuscript for publication. The first and last members of the writing committee vouch for the completeness and accuracy of the data and for the fidelity of the trial to the protocol and statistical analysis plan. Randomization We collected baseline data using a Web-based case-report form that included demographic data, the level of respiratory support, major coexisting illnesses, suitability of the trial treatment for a particular patient, and treatment availability at the trial site. Randomization was performed with the use of a Web-based system with concealment of the trial-group assignment.

Eligible and consenting patients were assigned in a 2:1 ratio to receive either the usual standard of care alone or the usual standard of care plus oral or intravenous dexamethasone (at a dose of 6 mg once daily) for up to 10 days (or until hospital discharge if sooner) or to receive one of the other suitable and available treatments that were being evaluated in the trial. For some patients, dexamethasone was unavailable at the hospital at the time of enrollment or was considered by the managing physician to be either definitely indicated or definitely contraindicated. These patients were excluded from entry in the randomized comparison between dexamethasone and usual care and hence were not included in this report. The randomly assigned treatment was prescribed by the treating clinician. Patients and local members of the trial staff were aware of the assigned treatments.

Procedures A single online follow-up form was to be completed when the patients were discharged or had died or at 28 days after randomization, whichever occurred first. Information was recorded regarding the patients’ adherence to the assigned treatment, receipt of other trial treatments, duration of admission, receipt of respiratory support (with duration and type), receipt of renal support, and vital status (including the cause of death). In addition, we obtained routine health care and registry data, including information on vital status (with date and cause of death), discharge from the hospital, and respiratory and renal support therapy. Outcome Measures The primary outcome was all-cause mortality within 28 days after randomization. Further analyses were specified at 6 months.

Secondary outcomes were the time until discharge from the hospital and, among patients not receiving invasive mechanical ventilation at the time of randomization, subsequent receipt of invasive mechanical ventilation (including extracorporeal membrane oxygenation) or death. Other prespecified clinical outcomes included cause-specific mortality, receipt of renal hemodialysis or hemofiltration, major cardiac arrhythmia (recorded in a subgroup), and receipt and duration of ventilation. Statistical Analysis As stated in the protocol, appropriate sample sizes could not be estimated when the trial was being planned at the start of the Covid-19 pandemic. As the trial progressed, the trial steering committee, whose members were unaware of the results of the trial comparisons, determined that if 28-day mortality was 20%, then the enrollment of at least 2000 patients in the dexamethasone group and 4000 in the usual care group would provide a power of at least 90% at a two-sided P value of 0.01 to detect a clinically relevant proportional reduction of 20% (an absolute difference of 4 percentage points) between the two groups. Consequently, on June 8, 2020, the steering committee closed recruitment to the dexamethasone group, since enrollment had exceeded 2000 patients.

For the primary outcome of 28-day mortality, the hazard ratio from Cox regression was used to estimate the mortality rate ratio. Among the few patients (0.1%) who had not been followed for 28 days by the time of the data cutoff on July 6, 2020, data were censored either on that date or on day 29 if the patient had already been discharged. That is, in the absence of any information to the contrary, these patients were assumed to have survived for 28 days. Kaplan–Meier survival curves were constructed to show cumulative mortality over the 28-day period. Cox regression was used to analyze the secondary outcome of hospital discharge within 28 days, with censoring of data on day 29 for patients who had died during hospitalization.

For the prespecified composite secondary outcome of invasive mechanical ventilation or death within 28 days (among patients who were not receiving invasive mechanical ventilation at randomization), the precise date of invasive mechanical ventilation was not available, so a log-binomial regression model was used to estimate the risk ratio. Table 1. Table 1. Characteristics of the Patients at Baseline, According to Treatment Assignment and Level of Respiratory Support. Through the play of chance in the unstratified randomization, the mean age was 1.1 years older among patients in the dexamethasone group than among those in the usual care group (Table 1).

To account for this imbalance in an important prognostic factor, estimates of rate ratios were adjusted for the baseline age in three categories (<70 years, 70 to 79 years, and ≥80 years). This adjustment was not specified in the first version of the statistical analysis plan but was added once the imbalance in age became apparent. Results without age adjustment (corresponding to the first version of the analysis plan) are provided in the Supplementary Appendix. Prespecified analyses of the primary outcome were performed in five subgroups, as defined by characteristics at randomization. Age, sex, level of respiratory support, days since symptom onset, and predicted 28-day mortality risk.

(One further prespecified subgroup analysis regarding race will be conducted once the data collection has been completed.) In prespecified subgroups, we estimated rate ratios (or risk ratios in some analyses) and their confidence intervals using regression models that included an interaction term between the treatment assignment and the subgroup of interest. Chi-square tests for linear trend across the subgroup-specific log estimates were then performed in accordance with the prespecified plan. All P values are two-sided and are shown without adjustment for multiple testing. All analyses were performed according to the intention-to-treat principle. The full database is held by the trial team, which collected the data from trial sites and performed the analyses at the Nuffield Department of Population Health, University of Oxford.Trial Design and Oversight We conducted a randomized, double-blind, placebo-controlled trial to evaluate postexposure prophylaxis with hydroxychloroquine after exposure to Covid-19.12 We randomly assigned participants in a 1:1 ratio to receive either hydroxychloroquine or placebo.

Participants had known exposure (by participant report) to a person with laboratory-confirmed Covid-19, whether as a household contact, a health care worker, or a person with other occupational exposures. Trial enrollment began on March 17, 2020, with an eligibility threshold to enroll within 3 days after exposure. The objective was to intervene before the median incubation period of 5 to 6 days. Because of limited access to prompt testing, health care workers could initially be enrolled on the basis of presumptive high-risk exposure to patients with pending tests. However, on March 23, eligibility was changed to exposure to a person with a positive polymerase-chain-reaction (PCR) assay for SARS-CoV-2, with the eligibility window extended to within 4 days after exposure.

This trial was approved by the institutional review board at the University of Minnesota and conducted under a Food and Drug Administration Investigational New Drug application. In Canada, the trial was approved by Health Canada. Ethics approvals were obtained from the Research Institute of the McGill University Health Centre, the University of Manitoba, and the University of Alberta. Participants We included participants who had household or occupational exposure to a person with confirmed Covid-19 at a distance of less than 6 ft for more than 10 minutes while wearing neither a face mask nor an eye shield (high-risk exposure) or while wearing a face mask but no eye shield (moderate-risk exposure). Participants were excluded if they were younger than 18 years of age, were hospitalized, or met other exclusion criteria (see the Supplementary Appendix, available with the full text of this article at NEJM.org).

Persons with symptoms of Covid-19 or with PCR-proven SARS-CoV-2 infection were excluded from this prevention trial but were separately enrolled in a companion clinical trial to treat early infection. Setting Recruitment was performed primarily with the use of social media outreach as well as traditional media platforms. Participants were enrolled nationwide in the United States and in the Canadian provinces of Quebec, Manitoba, and Alberta. Participants enrolled themselves through a secure Internet-based survey using the Research Electronic Data Capture (REDCap) system.13 After participants read the consent form, their comprehension of its contents was assessed. Participants provided a digitally captured signature to indicate informed consent.

We sent follow-up e-mail surveys on days 1, 5, 10, and 14. A survey at 4 to 6 weeks asked about any follow-up testing, illness, or hospitalizations. Participants who did not respond to follow-up surveys received text messages, e-mails, telephone calls, or a combination of these to ascertain their outcomes. When these methods were unsuccessful, the emergency contact provided by the enrollee was contacted to determine the participant’s illness and vital status. When all communication methods were exhausted, Internet searches for obituaries were performed to ascertain vital status.

Interventions Randomization occurred at research pharmacies in Minneapolis and Montreal. The trial statisticians generated a permuted-block randomization sequence using variably sized blocks of 2, 4, or 8, with stratification according to country. A research pharmacist sequentially assigned participants. The assignments were concealed from investigators and participants. Only pharmacies had access to the randomization sequence.

Hydroxychloroquine sulfate or placebo was dispensed and shipped overnight to participants by commercial courier. The dosing regimen for hydroxychloroquine was 800 mg (4 tablets) once, then 600 mg (3 tablets) 6 to 8 hours later, then 600 mg (3 tablets) daily for 4 more days for a total course of 5 days (19 tablets total). If participants had gastrointestinal upset, they were advised to divide the daily dose into two or three doses. We chose this hydroxychloroquine dosing regimen on the basis of pharmacokinetic simulations to achieve plasma concentrations above the SARS-CoV-2 in vitro half maximal effective concentration for 14 days.14 Placebo folate tablets, which were similar in appearance to the hydroxychloroquine tablets, were prescribed as an identical regimen for the control group. Rising Pharmaceuticals provided a donation of hydroxychloroquine, and some hydroxychloroquine was purchased.

Outcomes The primary outcome was prespecified as symptomatic illness confirmed by a positive molecular assay or, if testing was unavailable, Covid-19–related symptoms. We assumed that health care workers would have access to Covid-19 testing if symptomatic. However, access to testing was limited throughout the trial period. Covid-19–related symptoms were based on U.S. Council for State and Territorial Epidemiologists criteria for confirmed cases (positivity for SARS-Cov-2 on PCR assay), probable cases (the presence of cough, shortness of breath, or difficulty breathing, or the presence of two or more symptoms of fever, chills, rigors, myalgia, headache, sore throat, and new olfactory and taste disorders), and possible cases (the presence of one or more compatible symptoms, which could include diarrhea).15 All the participants had epidemiologic linkage,15 per trial eligibility criteria.

Four infectious disease physicians who were unaware of the trial-group assignments reviewed symptomatic participants to generate a consensus with respect to whether their condition met the case definition.15 Secondary outcomes included the incidence of hospitalization for Covid-19 or death, the incidence of PCR-confirmed SARS-CoV-2 infection, the incidence of Covid-19 symptoms, the incidence of discontinuation of the trial intervention owing to any cause, and the severity of symptoms (if any) at days 5 and 14 according to a visual analogue scale (scores ranged from 0 [no symptoms] to 10 [severe symptoms]). Data on adverse events were also collected with directed questioning for common side effects along with open-ended free text. Outcome data were measured within 14 days after trial enrollment. Outcome data including PCR testing results, possible Covid-19–related symptoms, adherence to the trial intervention, side effects, and hospitalizations were all collected through participant report. Details of trial conduct are provided in the protocol and statistical analysis plan, available at NEJM.org.

Sample Size We anticipated that illness compatible with Covid-19 would develop in 10% of close contacts exposed to Covid-19.9 Using Fisher’s exact method with a 50% relative effect size to reduce new symptomatic infections, a two-sided alpha of 0.05, and 90% power, we estimated that 621 persons would need to be enrolled in each group. With a pragmatic, Internet-based, self-referral recruitment strategy, we planned for a 20% incidence of attrition by increasing the sample size to 750 participants per group. We specified a priori that participants who were already symptomatic on day 1 before receiving hydroxychloroquine or placebo would be excluded from the prophylaxis trial and would instead be separately enrolled in the companion symptomatic treatment trial. Because the estimates for both incident symptomatic Covid-19 after an exposure and loss to follow-up were relatively unknown in early March 2020,9 the protocol prespecified a sample-size reestimation at the second interim analysis. This reestimation, which used the incidence of new infections in the placebo group and the observed percentage of participants lost to follow-up, was aimed at maintaining the ability to detect an effect size of a 50% relative reduction in new symptomatic infections.

Interim Analyses An independent data and safety monitoring board externally reviewed the data after 25% and 50% of the participants had completed 14 days of follow-up. Stopping guidelines were provided to the data and safety monitoring board with the use of a Lan–DeMets spending function analogue of the O’Brien–Fleming boundaries for the primary outcome. A conditional power analysis was performed at the second and third interim analysis with the option of early stopping for futility. At the second interim analysis on April 22, 2020, the sample size was reduced to 956 participants who could be evaluated with 90% power on the basis of the higher-than-expected event rate of infections in the control group. At the third interim analysis on May 6, the trial was halted on the basis of a conditional power of less than 1%, since it was deemed futile to continue.

Statistical Analysis We assessed the incidence of Covid-19 disease by day 14 with Fisher’s exact test. Secondary outcomes with respect to percentage of patients were also compared with Fisher’s exact test. Among participants in whom incident illness compatible with Covid-19 developed, we summarized the symptom severity score at day 14 with the median and interquartile range and assessed the distributions with a Kruskal–Wallis test. We conducted all analyses with SAS software, version 9.4 (SAS Institute), according to the intention-to-treat principle, with two-sided type I error with an alpha of 0.05. For participants with missing outcome data, we conducted a sensitivity analysis with their outcomes excluded or included as an event.

Subgroups that were specified a priori included type of contact (household vs. Health care), days from exposure to enrollment, age, and sex.Announced on May 15, Operation Warp Speed (OWS) — a partnership of the Department of Health and Human Services (HHS), the Department of Defense (DOD), and the private sector — aims to accelerate control of the Covid-19 pandemic by advancing development, manufacturing, and distribution of vaccines, therapeutics, and diagnostics. OWS is providing support to promising candidates and enabling the expeditious, parallel execution of the necessary steps toward approval or authorization of safe products by the Food and Drug Administration (FDA).The partnership grew out of an acknowledged need to fundamentally restructure the way the U.S. Government typically supports product development and vaccine distribution. The initiative was premised on setting a “stretch goal” — one that initially seemed impossible but that is becoming increasingly achievable.The concept of an integrated structure for Covid-19 countermeasure research and development across the U.S.

Government was based on experience with Zika and the Zika Leadership Group led by the National Institutes of Health (NIH) and the assistant secretary for preparedness and response (ASPR). One of us (M.S.) serves as OWS chief advisor. We are drawing on expertise from the NIH, ASPR, the Centers for Disease Control and Prevention (CDC), the Biomedical Advanced Research and Development Authority (BARDA), and the DOD, including the Joint Program Executive Office for Chemical, Biological, Radiological and Nuclear Defense and the Defense Advanced Research Projects Agency. OWS has engaged experts in all critical aspects of medical countermeasure research, development, manufacturing, and distribution to work in close coordination.The initiative set ambitious objectives. To deliver tens of millions of doses of a SARS-CoV-2 vaccine — with demonstrated safety and efficacy, and approved or authorized by the FDA for use in the U.S.

Population — beginning at the end of 2020 and to have as many as 300 million doses of such vaccines available and deployed by mid-2021. The pace and scope of such a vaccine effort are unprecedented. The 2014 West African Ebola virus epidemic spurred rapid vaccine development, but though preclinical data existed before the outbreak, a period of 12 months was required to progress from phase 1 first-in-human trials to phase 3 efficacy trials. OWS aims to compress this time frame even further. SARS-CoV-2 vaccine development began in January, phase 1 clinical studies in March, and the first phase 3 trials in July.

Our objectives are based on advances in vaccine platform technology, improved understanding of safe and efficacious vaccine design, and similarities between the SARS-CoV-1 and SARS-CoV-2 disease mechanisms.OWS’s role is to enable, accelerate, harmonize, and advise the companies developing the selected vaccines. The companies will execute the clinical or process development and manufacturing plans, while OWS leverages the full capacity of the U.S. Government to ensure that no technical, logistic, or financial hurdles hinder vaccine development or deployment.OWS selected vaccine candidates on the basis of four criteria. We required candidates to have robust preclinical data or early-stage clinical trial data supporting their potential for clinical safety and efficacy. Candidates had to have the potential, with our acceleration support, to enter large phase 3 field efficacy trials this summer or fall (July to November 2020) and, assuming continued active transmission of the virus, to deliver efficacy outcomes by the end of 2020 or the first half of 2021.

Candidates had to be based on vaccine-platform technologies permitting fast and effective manufacturing, and their developers had to demonstrate the industrial process scalability, yields, and consistency necessary to reliably produce more than 100 million doses by mid-2021. Finally, candidates had to use one of four vaccine-platform technologies that we believe are the most likely to yield a safe and effective vaccine against Covid-19. The mRNA platform, the replication-defective live-vector platform, the recombinant-subunit-adjuvanted protein platform, or the attenuated replicating live-vector platform.OWS’s strategy relies on a few key principles. First, we sought to build a diverse project portfolio that includes two vaccine candidates based on each of the four platform technologies. Such diversification mitigates the risk of failure due to safety, efficacy, industrial manufacturability, or scheduling factors and may permit selection of the best vaccine platform for each subpopulation at risk for contracting or transmitting Covid-19, including older adults, frontline and essential workers, young adults, and pediatric populations.

In addition, advancing eight vaccines in parallel will increase the chances of delivering 300 million doses in the first half of 2021.Second, we must accelerate vaccine program development without compromising safety, efficacy, or product quality. Clinical development, process development, and manufacturing scale-up can be substantially accelerated by running all streams, fully resourced, in parallel. Doing so requires taking on substantial financial risk, as compared with the conventional sequential development approach. OWS will maximize the size of phase 3 trials (30,000 to 50,000 participants each) and optimize trial-site location by consulting daily epidemiologic and disease-forecasting models to ensure the fastest path to an efficacy readout. Such large trials also increase the safety data set for each candidate vaccine.With heavy up-front investment, companies can conduct clinical operations and site preparation for these phase 3 efficacy trials even as they file their Investigational New Drug application (IND) for their phase 1 studies, thereby ensuring immediate initiation of phase 3 when they get a green light from the FDA.

To permit appropriate comparisons among the vaccine candidates and to optimize vaccine utilization after approval by the FDA, the phase 3 trial end points and assay readouts have been harmonized through a collaborative effort involving the National Institute of Allergy and Infectious Diseases (NIAID), the Coronavirus Prevention Network, OWS, and the sponsor companies.Finally, OWS is supporting the companies financially and technically to commence process development and scale up manufacturing while their vaccines are in preclinical or very early clinical stages. To ensure that industrial processes are set, running, and validated for FDA inspection when phase 3 trials end, OWS is also supporting facility building or refurbishing, equipment fitting, staff hiring and training, raw-material sourcing, technology transfer and validation, bulk product processing into vials, and acquisition of ample vials, syringes, and needles for each vaccine candidate. We aim to have stockpiled, at OWS’s expense, a few tens of millions of vaccine doses that could be swiftly deployed once FDA approval is obtained.This strategy aims to accelerate vaccine development without curtailing the critical steps required by sound science and regulatory standards. The FDA recently reissued guidance and standards that will be used to assess each vaccine for a Biologics License Application (BLA). Alternatively, the agency could decide to issue an Emergency Use Authorization to permit vaccine administration before all BLA procedures are completed.Of the eight vaccines in OWS’s portfolio, six have been announced and partnerships executed with the companies.

Moderna and Pfizer/BioNTech (both mRNA), AstraZeneca and Janssen (both replication-defective live-vector), and Novavax and Sanofi/GSK (both recombinant-subunit-adjuvanted protein). These candidates cover three of the four platform technologies and are currently in clinical trials. The remaining two candidates will enter trials soon.Moderna developed its RNA vaccine in collaboration with the NIAID, began its phase 1 trial in March, recently published encouraging safety and immunogenicity data,1 and entered phase 3 on July 27. Pfizer and BioNTech’s RNA vaccine also produced encouraging phase 1 results2 and started its phase 3 trial on July 27. The ChAdOx replication-defective live-vector vaccine developed by AstraZeneca and Oxford University is in phase 3 trials in the United Kingdom, Brazil, and South Africa, and it should enter U.S.

Phase 3 trials in August.3 The Janssen Ad26 Covid-19 replication-defective live-vector vaccine has demonstrated excellent protection in nonhuman primate models and began its U.S. Phase 1 trial on July 27. It should be in phase 3 trials in mid-September. Novavax completed a phase 1 trial of its recombinant-subunit-adjuvanted protein vaccine in Australia and should enter phase 3 trials in the United States by the end of September.4 Sanofi/GSK is completing preclinical development steps and plans to commence a phase 1 trial in early September and to be well into phase 3 by year’s end.5On the process-development front, the RNA vaccines are already being manufactured at scale. The other candidates are well advanced in their scale-up development, and manufacturing sites are being refurbished.While development and manufacturing proceed, the HHS–DOD partnership is laying the groundwork for vaccine distribution, subpopulation prioritization, financing, and logistic support.

We are working with bioethicists and experts from the NIH, the CDC, BARDA, and the Centers for Medicare and Medicaid Services to address these critical issues. We will receive recommendations from the CDC Advisory Committee on Immunization Practices, and we are working to ensure that the most vulnerable and at-risk persons will receive vaccine doses once they are ready. Prioritization will also depend on the relative performance of each vaccine and its suitability for particular populations. Because some technologies have limited previous data on safety in humans, the long-term safety of these vaccines will be carefully assessed using pharmacovigilance surveillance strategies.No scientific enterprise could guarantee success by January 2021, but the strategic decisions and choices we’ve made, the support the government has provided, and the accomplishments to date make us optimistic that we will succeed in this unprecedented endeavor..

Patients Figure buy acyclovir online canada 1. Figure 1. Enrollment and buy acyclovir online canada Randomization. Of the 1107 patients who were assessed for eligibility, 1063 underwent randomization.

541 were assigned to the buy acyclovir online canada remdesivir group and 522 to the placebo group (Figure 1). Of those assigned to receive remdesivir, 531 patients (98.2%) received the treatment as assigned. Forty-nine patients had remdesivir treatment discontinued before day 10 because of an adverse event or a serious adverse buy acyclovir online canada event other than death (36 patients) or because the patient withdrew consent (13). Of those assigned to receive placebo, 518 patients (99.2%) received placebo as assigned.

Fifty-three patients discontinued placebo before day 10 because of an adverse event or a serious adverse event other than death (36 patients), because the patient withdrew consent (15), or because the patient was found to be ineligible for trial enrollment (2). As of April 28, 2020, a total of 391 patients in the remdesivir group and 340 in the placebo group had completed the buy acyclovir online canada trial through day 29, recovered, or died. Eight patients who received remdesivir and 9 who received placebo terminated their participation in the trial before day 29. There were 132 patients in the remdesivir group and 169 in the placebo group who had not recovered and had buy acyclovir online canada not completed the day 29 follow-up visit.

The analysis population included 1059 patients for whom we have at least some postbaseline data available (538 in the remdesivir group and 521 in the placebo group). Four of the 1063 patients were not included in the primary analysis because no postbaseline data were available at the time of the buy acyclovir online canada database freeze. Table 1. Table 1 buy acyclovir online canada.

Demographic and Clinical Characteristics at Baseline. The mean age of patients was 58.9 years, and 64.3% were male (Table 1). On the basis of the evolving epidemiology of Covid-19 during the trial, 79.8% of patients were enrolled at sites in North America, 15.3% buy acyclovir online canada in Europe, and 4.9% in Asia (Table S1). Overall, 53.2% of the patients were white, 20.6% were black, 12.6% were Asian, and 13.6% were designated as other or not reported.

249 (23.4%) buy acyclovir online canada were Hispanic or Latino. Most patients had either one (27.0%) or two or more (52.1%) of the prespecified coexisting conditions at enrollment, most commonly hypertension (49.6%), obesity (37.0%), and type 2 diabetes mellitus (29.7%). The median number of days between symptom onset and randomization was 9 (interquartile buy acyclovir online canada range, 6 to 12). Nine hundred forty-three (88.7%) patients had severe disease at enrollment as defined in the Supplementary Appendix.

272 (25.6%) patients met category 7 criteria on the ordinal scale, 197 (18.5%) category 6, 421 (39.6%) category 5, and 127 buy acyclovir online canada (11.9%) category 4. There were 46 (4.3%) patients who had missing ordinal scale data at enrollment. No substantial imbalances in baseline characteristics were observed between the remdesivir group and the placebo group. Primary Outcome buy acyclovir online canada Figure 2.

Time to buy acyclovir online canada Recovery According to Subgroup. The widths of the confidence intervals have not been adjusted for multiplicity and therefore cannot be used to infer treatment effects. Race and ethnic group were reported by the patients buy acyclovir online canada. Patients in the remdesivir group had a shorter time to recovery than patients in the placebo group (median, 11 days, as compared with 15 days.

Rate ratio for recovery, 1.32. 95% confidence interval buy acyclovir online canada [CI], 1.12 to 1.55. P<0.001. 1059 patients (Figure buy acyclovir online canada 2 and Table 2).

Among patients with a baseline ordinal score of 5 (421 patients), the rate ratio for recovery was 1.47 (95% CI, 1.17 to 1.84). Among patients with a baseline score of 4 (127 patients) and those with a baseline score of 6 (197 patients), the rate ratio estimates for recovery were 1.38 (95% CI, 0.94 to 2.03) and 1.20 buy acyclovir online canada (95% CI, 0.79 to 1.81), respectively. For those receiving mechanical ventilation or ECMO at enrollment (baseline ordinal scores of 7. 272 patients), buy acyclovir online canada the rate ratio for recovery was 0.95 (95% CI, 0.64 to 1.42).

A test of interaction of treatment with baseline score on the ordinal scale was not significant. An analysis adjusting for baseline ordinal score as a stratification variable was conducted to evaluate the overall effect (of the percentage of patients in each ordinal score category at baseline) on the primary outcome. This adjusted analysis produced a similar treatment-effect estimate (rate ratio buy acyclovir online canada for recovery, 1.31. 95% CI, 1.12 to 1.54.

1017 patients) buy acyclovir online canada. Table S2 in the Supplementary Appendix shows results according to the baseline severity stratum of mild-to-moderate as compared with severe. Patients who underwent randomization during the first 10 days after the onset of symptoms had a rate ratio for buy acyclovir online canada recovery of 1.28 (95% CI, 1.05 to 1.57. 664 patients), whereas patients who underwent randomization more than 10 days after the onset of symptoms had a rate ratio for recovery of 1.38 (95% CI, 1.05 to 1.81.

380 patients) buy acyclovir online canada (Figure 3). Key Secondary Outcome The odds of improvement in the ordinal scale score were higher in the remdesivir group, as determined by a proportional odds model at the day 15 visit, than in the placebo group (odds ratio for improvement, 1.50. 95% CI, 1.18 to 1.91. P=0.001.

844 patients) (Table 2 and Fig. S5). Mortality was numerically lower in the remdesivir group than in the placebo group, but the difference was not significant (hazard ratio for death, 0.70. 95% CI, 0.47 to 1.04.

1059 patients). The Kaplan–Meier estimates of mortality by 14 days were 7.1% and 11.9% in the remdesivir and placebo groups, respectively (Table 2). The Kaplan–Meier estimates of mortality by 28 days are not reported in this preliminary analysis, given the large number of patients that had yet to complete day 29 visits. An analysis with adjustment for baseline ordinal score as a stratification variable showed a hazard ratio for death of 0.74 (95% CI, 0.50 to 1.10).

Safety Outcomes Serious adverse events occurred in 114 patients (21.1%) in the remdesivir group and 141 patients (27.0%) in the placebo group (Table S3). 4 events (2 in each group) were judged by site investigators to be related to remdesivir or placebo. There were 28 serious respiratory failure adverse events in the remdesivir group (5.2% of patients) and 42 in the placebo group (8.0% of patients). Acute respiratory failure, hypotension, viral pneumonia, and acute kidney injury were slightly more common among patients in the placebo group.

No deaths were considered to be related to treatment assignment, as judged by the site investigators. Grade 3 or 4 adverse events occurred in 156 patients (28.8%) in the remdesivir group and in 172 in the placebo group (33.0%) (Table S4). The most common adverse events in the remdesivir group were anemia or decreased hemoglobin (43 events [7.9%], as compared with 47 [9.0%] in the placebo group). Acute kidney injury, decreased estimated glomerular filtration rate or creatinine clearance, or increased blood creatinine (40 events [7.4%], as compared with 38 [7.3%]).

Pyrexia (27 events [5.0%], as compared with 17 [3.3%]). Hyperglycemia or increased blood glucose level (22 events [4.1%], as compared with 17 [3.3%]). And increased aminotransferase levels including alanine aminotransferase, aspartate aminotransferase, or both (22 events [4.1%], as compared with 31 [5.9%]). Otherwise, the incidence of adverse events was not found to be significantly different between the remdesivir group and the placebo group.Trial Population Table 1.

Table 1. Characteristics of the Participants in the mRNA-1273 Trial at Enrollment. The 45 enrolled participants received their first vaccination between March 16 and April 14, 2020 (Fig. S1).

Three participants did not receive the second vaccination, including one in the 25-μg group who had urticaria on both legs, with onset 5 days after the first vaccination, and two (one in the 25-μg group and one in the 250-μg group) who missed the second vaccination window owing to isolation for suspected Covid-19 while the test results, ultimately negative, were pending. All continued to attend scheduled trial visits. The demographic characteristics of participants at enrollment are provided in Table 1. Vaccine Safety No serious adverse events were noted, and no prespecified trial halting rules were met.

As noted above, one participant in the 25-μg group was withdrawn because of an unsolicited adverse event, transient urticaria, judged to be related to the first vaccination. Figure 1. Figure 1. Systemic and Local Adverse Events.

The severity of solicited adverse events was graded as mild, moderate, or severe (see Table S1).After the first vaccination, solicited systemic adverse events were reported by 5 participants (33%) in the 25-μg group, 10 (67%) in the 100-μg group, and 8 (53%) in the 250-μg group. All were mild or moderate in severity (Figure 1 and Table S2). Solicited systemic adverse events were more common after the second vaccination and occurred in 7 of 13 participants (54%) in the 25-μg group, all 15 in the 100-μg group, and all 14 in the 250-μg group, with 3 of those participants (21%) reporting one or more severe events. None of the participants had fever after the first vaccination.

After the second vaccination, no participants in the 25-μg group, 6 (40%) in the 100-μg group, and 8 (57%) in the 250-μg group reported fever. One of the events (maximum temperature, 39.6°C) in the 250-μg group was graded severe. (Additional details regarding adverse events for that participant are provided in the Supplementary Appendix.) Local adverse events, when present, were nearly all mild or moderate, and pain at the injection site was common. Across both vaccinations, solicited systemic and local adverse events that occurred in more than half the participants included fatigue, chills, headache, myalgia, and pain at the injection site.

Evaluation of safety clinical laboratory values of grade 2 or higher and unsolicited adverse events revealed no patterns of concern (Supplementary Appendix and Table S3). SARS-CoV-2 Binding Antibody Responses Table 2. Table 2. Geometric Mean Humoral Immunogenicity Assay Responses to mRNA-1273 in Participants and in Convalescent Serum Specimens.

Figure 2. Figure 2. SARS-CoV-2 Antibody and Neutralization Responses. Shown are geometric mean reciprocal end-point enzyme-linked immunosorbent assay (ELISA) IgG titers to S-2P (Panel A) and receptor-binding domain (Panel B), PsVNA ID50 responses (Panel C), and live virus PRNT80 responses (Panel D).

In Panel A and Panel B, boxes and horizontal bars denote interquartile range (IQR) and median area under the curve (AUC), respectively. Whisker endpoints are equal to the maximum and minimum values below or above the median ±1.5 times the IQR. The convalescent serum panel includes specimens from 41 participants. Red dots indicate the 3 specimens that were also tested in the PRNT assay.

The other 38 specimens were used to calculate summary statistics for the box plot in the convalescent serum panel. In Panel C, boxes and horizontal bars denote IQR and median ID50, respectively. Whisker end points are equal to the maximum and minimum values below or above the median ±1.5 times the IQR. In the convalescent serum panel, red dots indicate the 3 specimens that were also tested in the PRNT assay.

The other 38 specimens were used to calculate summary statistics for the box plot in the convalescent panel. In Panel D, boxes and horizontal bars denote IQR and median PRNT80, respectively. Whisker end points are equal to the maximum and minimum values below or above the median ±1.5 times the IQR. The three convalescent serum specimens were also tested in ELISA and PsVNA assays.

Because of the time-intensive nature of the PRNT assay, for this preliminary report, PRNT results were available only for the 25-μg and 100-μg dose groups.Binding antibody IgG geometric mean titers (GMTs) to S-2P increased rapidly after the first vaccination, with seroconversion in all participants by day 15 (Table 2 and Figure 2A). Dose-dependent responses to the first and second vaccinations were evident. Receptor-binding domain–specific antibody responses were similar in pattern and magnitude (Figure 2B). For both assays, the median magnitude of antibody responses after the first vaccination in the 100-μg and 250-μg dose groups was similar to the median magnitude in convalescent serum specimens, and in all dose groups the median magnitude after the second vaccination was in the upper quartile of values in the convalescent serum specimens.

The S-2P ELISA GMTs at day 57 (299,751 [95% confidence interval {CI}, 206,071 to 436,020] in the 25-μg group, 782,719 [95% CI, 619,310 to 989,244] in the 100-μg group, and 1,192,154 [95% CI, 924,878 to 1,536,669] in the 250-μg group) exceeded that in the convalescent serum specimens (142,140 [95% CI, 81,543 to 247,768]). SARS-CoV-2 Neutralization Responses No participant had detectable PsVNA responses before vaccination. After the first vaccination, PsVNA responses were detected in less than half the participants, and a dose effect was seen (50% inhibitory dilution [ID50]. Figure 2C, Fig.

S8, and Table 2. 80% inhibitory dilution [ID80]. Fig. S2 and Table S6).

However, after the second vaccination, PsVNA responses were identified in serum samples from all participants. The lowest responses were in the 25-μg dose group, with a geometric mean ID50 of 112.3 (95% CI, 71.2 to 177.1) at day 43. The higher responses in the 100-μg and 250-μg groups were similar in magnitude (geometric mean ID50, 343.8 [95% CI, 261.2 to 452.7] and 332.2 [95% CI, 266.3 to 414.5], respectively, at day 43). These responses were similar to values in the upper half of the distribution of values for convalescent serum specimens.

Before vaccination, no participant had detectable 80% live-virus neutralization at the highest serum concentration tested (1:8 dilution) in the PRNT assay. At day 43, wild-type virus–neutralizing activity capable of reducing SARS-CoV-2 infectivity by 80% or more (PRNT80) was detected in all participants, with geometric mean PRNT80 responses of 339.7 (95% CI, 184.0 to 627.1) in the 25-μg group and 654.3 (95% CI, 460.1 to 930.5) in the 100-μg group (Figure 2D). Neutralizing PRNT80 average responses were generally at or above the values of the three convalescent serum specimens tested in this assay. Good agreement was noted within and between the values from binding assays for S-2P and receptor-binding domain and neutralizing activity measured by PsVNA and PRNT (Figs.

S3 through S7), which provides orthogonal support for each assay in characterizing the humoral response induced by mRNA-1273. SARS-CoV-2 T-Cell Responses The 25-μg and 100-μg doses elicited CD4 T-cell responses (Figs. S9 and S10) that on stimulation by S-specific peptide pools were strongly biased toward expression of Th1 cytokines (tumor necrosis factor α >. Interleukin 2 >.

Interferon γ), with minimal type 2 helper T-cell (Th2) cytokine expression (interleukin 4 and interleukin 13). CD8 T-cell responses to S-2P were detected at low levels after the second vaccination in the 100-μg dose group (Fig. S11).Trial Design and Oversight The RECOVERY trial was designed to evaluate the effects of potential treatments in patients hospitalized with Covid-19 at 176 National Health Service organizations in the United Kingdom and was supported by the National Institute for Health Research Clinical Research Network. (Details regarding this trial are provided in the Supplementary Appendix, available with the full text of this article at NEJM.org.) The trial is being coordinated by the Nuffield Department of Population Health at the University of Oxford, the trial sponsor.

Although the randomization of patients to receive dexamethasone, hydroxychloroquine, or lopinavir–ritonavir has now been stopped, the trial continues randomization to groups receiving azithromycin, tocilizumab, or convalescent plasma. Hospitalized patients were eligible for the trial if they had clinically suspected or laboratory-confirmed SARS-CoV-2 infection and no medical history that might, in the opinion of the attending clinician, put patients at substantial risk if they were to participate in the trial. Initially, recruitment was limited to patients who were at least 18 years of age, but the age limit was removed starting on May 9, 2020. Pregnant or breast-feeding women were eligible.

Written informed consent was obtained from all the patients or from a legal representative if they were unable to provide consent. The trial was conducted in accordance with the principles of the Good Clinical Practice guidelines of the International Conference on Harmonisation and was approved by the U.K. Medicines and Healthcare Products Regulatory Agency and the Cambridge East Research Ethics Committee. The protocol with its statistical analysis plan is available at NEJM.org and on the trial website at www.recoverytrial.net.

The initial version of the manuscript was drafted by the first and last authors, developed by the writing committee, and approved by all members of the trial steering committee. The funders had no role in the analysis of the data, in the preparation or approval of the manuscript, or in the decision to submit the manuscript for publication. The first and last members of the writing committee vouch for the completeness and accuracy of the data and for the fidelity of the trial to the protocol and statistical analysis plan. Randomization We collected baseline data using a Web-based case-report form that included demographic data, the level of respiratory support, major coexisting illnesses, suitability of the trial treatment for a particular patient, and treatment availability at the trial site.

Randomization was performed with the use of a Web-based system with concealment of the trial-group assignment. Eligible and consenting patients were assigned in a 2:1 ratio to receive either the usual standard of care alone or the usual standard of care plus oral or intravenous dexamethasone (at a dose of 6 mg once daily) for up to 10 days (or until hospital discharge if sooner) or to receive one of the other suitable and available treatments that were being evaluated in the trial. For some patients, dexamethasone was unavailable at the hospital at the time of enrollment or was considered by the managing physician to be either definitely indicated or definitely contraindicated. These patients were excluded from entry in the randomized comparison between dexamethasone and usual care and hence were not included in this report.

The randomly assigned treatment was prescribed by the treating clinician. Patients and local members of the trial staff were aware of the assigned treatments. Procedures A single online follow-up form was to be completed when the patients were discharged or had died or at 28 days after randomization, whichever occurred first. Information was recorded regarding the patients’ adherence to the assigned treatment, receipt of other trial treatments, duration of admission, receipt of respiratory support (with duration and type), receipt of renal support, and vital status (including the cause of death).

In addition, we obtained routine health care and registry data, including information on vital status (with date and cause of death), discharge from the hospital, and respiratory and renal support therapy. Outcome Measures The primary outcome was all-cause mortality within 28 days after randomization. Further analyses were specified at 6 months. Secondary outcomes were the time until discharge from the hospital and, among patients not receiving invasive mechanical ventilation at the time of randomization, subsequent receipt of invasive mechanical ventilation (including extracorporeal membrane oxygenation) or death.

Other prespecified clinical outcomes included cause-specific mortality, receipt of renal hemodialysis or hemofiltration, major cardiac arrhythmia (recorded in a subgroup), and receipt and duration of ventilation. Statistical Analysis As stated in the protocol, appropriate sample sizes could not be estimated when the trial was being planned at the start of the Covid-19 pandemic. As the trial progressed, the trial steering committee, whose members were unaware of the results of the trial comparisons, determined that if 28-day mortality was 20%, then the enrollment of at least 2000 patients in the dexamethasone group and 4000 in the usual care group would provide a power of at least 90% at a two-sided P value of 0.01 to detect a clinically relevant proportional reduction of 20% (an absolute difference of 4 percentage points) between the two groups. Consequently, on June 8, 2020, the steering committee closed recruitment to the dexamethasone group, since enrollment had exceeded 2000 patients.

For the primary outcome of 28-day mortality, the hazard ratio from Cox regression was used to estimate the mortality rate ratio. Among the few patients (0.1%) who had not been followed for 28 days by the time of the data cutoff on July 6, 2020, data were censored either on that date or on day 29 if the patient had already been discharged. That is, in the absence of any information to the contrary, these patients were assumed to have survived for 28 days. Kaplan–Meier survival curves were constructed to show cumulative mortality over the 28-day period.

Cox regression was used to analyze the secondary outcome of hospital discharge within 28 days, with censoring of data on day 29 for patients who had died during hospitalization. For the prespecified composite secondary outcome of invasive mechanical ventilation or death within 28 days (among patients who were not receiving invasive mechanical ventilation at randomization), the precise date of invasive mechanical ventilation was not available, so a log-binomial regression model was used to estimate the risk ratio. Table 1. Table 1.

Characteristics of the Patients at Baseline, According to Treatment Assignment and Level of Respiratory Support. Through the play of chance in the unstratified randomization, the mean age was 1.1 years older among patients in the dexamethasone group than among those in the usual care group (Table 1). To account for this imbalance in an important prognostic factor, estimates of rate ratios were adjusted for the baseline age in three categories (<70 years, 70 to 79 years, and ≥80 years). This adjustment was not specified in the first version of the statistical analysis plan but was added once the imbalance in age became apparent.

Results without age adjustment (corresponding to the first version of the analysis plan) are provided in the Supplementary Appendix. Prespecified analyses of the primary outcome were performed in five subgroups, as defined by characteristics at randomization. Age, sex, level of respiratory support, days since symptom onset, and predicted 28-day mortality risk. (One further prespecified subgroup analysis regarding race will be conducted once the data collection has been completed.) In prespecified subgroups, we estimated rate ratios (or risk ratios in some analyses) and their confidence intervals using regression models that included an interaction term between the treatment assignment and the subgroup of interest.

Chi-square tests for linear trend across the subgroup-specific log estimates were then performed in accordance with the prespecified plan. All P values are two-sided and are shown without adjustment for multiple testing. All analyses were performed according to the intention-to-treat principle. The full database is held by the trial team, which collected the data from trial sites and performed the analyses at the Nuffield Department of Population Health, University of Oxford.Trial Design and Oversight We conducted a randomized, double-blind, placebo-controlled trial to evaluate postexposure prophylaxis with hydroxychloroquine after exposure to Covid-19.12 We randomly assigned participants in a 1:1 ratio to receive either hydroxychloroquine or placebo.

Participants had known exposure (by participant report) to a person with laboratory-confirmed Covid-19, whether as a household contact, a health care worker, or a person with other occupational exposures. Trial enrollment began on March 17, 2020, with an eligibility threshold to enroll within 3 days after exposure. The objective was to intervene before the median incubation period of 5 to 6 days. Because of limited access to prompt testing, health care workers could initially be enrolled on the basis of presumptive high-risk exposure to patients with pending tests.

However, on March 23, eligibility was changed to exposure to a person with a positive polymerase-chain-reaction (PCR) assay for SARS-CoV-2, with the eligibility window extended to within 4 days after exposure. This trial was approved by the institutional review board at the University of Minnesota and conducted under a Food and Drug Administration Investigational New Drug application. In Canada, the trial was approved by Health Canada. Ethics approvals were obtained from the Research Institute of the McGill University Health Centre, the University of Manitoba, and the University of Alberta.

Participants We included participants who had household or occupational exposure to a person with confirmed Covid-19 at a distance of less than 6 ft for more than 10 minutes while wearing neither a face mask nor an eye shield (high-risk exposure) or while wearing a face mask but no eye shield (moderate-risk exposure). Participants were excluded if they were younger than 18 years of age, were hospitalized, or met other exclusion criteria (see the Supplementary Appendix, available with the full text of this article at NEJM.org). Persons with symptoms of Covid-19 or with PCR-proven SARS-CoV-2 infection were excluded from this prevention trial but were separately enrolled in a companion clinical trial to treat early infection. Setting Recruitment was performed primarily with the use of social media outreach as well as traditional media platforms.

Participants were enrolled nationwide in the United States and in the Canadian provinces of Quebec, Manitoba, and Alberta. Participants enrolled themselves through a secure Internet-based survey using the Research Electronic Data Capture (REDCap) system.13 After participants read the consent form, their comprehension of its contents was assessed. Participants provided a digitally captured signature to indicate informed consent. We sent follow-up e-mail surveys on days 1, 5, 10, and 14.

A survey at 4 to 6 weeks asked about any follow-up testing, illness, or hospitalizations. Participants who did not respond to follow-up surveys received text messages, e-mails, telephone calls, or a combination of these to ascertain their outcomes. When these methods were unsuccessful, the emergency contact provided by the enrollee was contacted to determine the participant’s illness and vital status. When all communication methods were exhausted, Internet searches for obituaries were performed to ascertain vital status.

Interventions Randomization occurred at research pharmacies in Minneapolis and Montreal. The trial statisticians generated a permuted-block randomization sequence using variably sized blocks of 2, 4, or 8, with stratification according to country. A research pharmacist sequentially assigned participants. The assignments were concealed from investigators and participants.

Only pharmacies had access to the randomization sequence. Hydroxychloroquine sulfate or placebo was dispensed and shipped overnight to participants by commercial courier. The dosing regimen for hydroxychloroquine was 800 mg (4 tablets) once, then 600 mg (3 tablets) 6 to 8 hours later, then 600 mg (3 tablets) daily for 4 more days for a total course of 5 days (19 tablets total). If participants had gastrointestinal upset, they were advised to divide the daily dose into two or three doses.

We chose this hydroxychloroquine dosing regimen on the basis of pharmacokinetic simulations to achieve plasma concentrations above the SARS-CoV-2 in vitro half maximal effective concentration for 14 days.14 Placebo folate tablets, which were similar in appearance to the hydroxychloroquine tablets, were prescribed as an identical regimen for the control group. Rising Pharmaceuticals provided a donation of hydroxychloroquine, and some hydroxychloroquine was purchased. Outcomes The primary outcome was prespecified as symptomatic illness confirmed by a positive molecular assay or, if testing was unavailable, Covid-19–related symptoms. We assumed that health care workers would have access to Covid-19 testing if symptomatic.

However, access to testing was limited throughout the trial period. Covid-19–related symptoms were based on U.S. Council for State and Territorial Epidemiologists criteria for confirmed cases (positivity for SARS-Cov-2 on PCR assay), probable cases (the presence of cough, shortness of breath, or difficulty breathing, or the presence of two or more symptoms of fever, chills, rigors, myalgia, headache, sore throat, and new olfactory and taste disorders), and possible cases (the presence of one or more compatible symptoms, which could include diarrhea).15 All the participants had epidemiologic linkage,15 per trial eligibility criteria. Four infectious disease physicians who were unaware of the trial-group assignments reviewed symptomatic participants to generate a consensus with respect to whether their condition met the case definition.15 Secondary outcomes included the incidence of hospitalization for Covid-19 or death, the incidence of PCR-confirmed SARS-CoV-2 infection, the incidence of Covid-19 symptoms, the incidence of discontinuation of the trial intervention owing to any cause, and the severity of symptoms (if any) at days 5 and 14 according to a visual analogue scale (scores ranged from 0 [no symptoms] to 10 [severe symptoms]).

Data on adverse events were also collected with directed questioning for common side effects along with open-ended free text. Outcome data were measured within 14 days after trial enrollment. Outcome data including PCR testing results, possible Covid-19–related symptoms, adherence to the trial intervention, side effects, and hospitalizations were all collected through participant report. Details of trial conduct are provided in the protocol and statistical analysis plan, available at NEJM.org.

Sample Size We anticipated that illness compatible with Covid-19 would develop in 10% of close contacts exposed to Covid-19.9 Using Fisher’s exact method with a 50% relative effect size to reduce new symptomatic infections, a two-sided alpha of 0.05, and 90% power, we estimated that 621 persons would need to be enrolled in each group. With a pragmatic, Internet-based, self-referral recruitment strategy, we planned for a 20% incidence of attrition by increasing the sample size to 750 participants per group. We specified a priori that participants who were already symptomatic on day 1 before receiving hydroxychloroquine or placebo would be excluded from the prophylaxis trial and would instead be separately enrolled in the companion symptomatic treatment trial. Because the estimates for both incident symptomatic Covid-19 after an exposure and loss to follow-up were relatively unknown in early March 2020,9 the protocol prespecified a sample-size reestimation at the second interim analysis.

This reestimation, which used the incidence of new infections in the placebo group and the observed percentage of participants lost to follow-up, was aimed at maintaining the ability to detect an effect size of a 50% relative reduction in new symptomatic infections. Interim Analyses An independent data and safety monitoring board externally reviewed the data after 25% and 50% of the participants had completed 14 days of follow-up. Stopping guidelines were provided to the data and safety monitoring board with the use of a Lan–DeMets spending function analogue of the O’Brien–Fleming boundaries for the primary outcome. A conditional power analysis was performed at the second and third interim analysis with the option of early stopping for futility.

At the second interim analysis on April 22, 2020, the sample size was reduced to 956 participants who could be evaluated with 90% power on the basis of the higher-than-expected event rate of infections in the control group. At the third interim analysis on May 6, the trial was halted on the basis of a conditional power of less than 1%, since it was deemed futile to continue. Statistical Analysis We assessed the incidence of Covid-19 disease by day 14 with Fisher’s exact test. Secondary outcomes with respect to percentage of patients were also compared with Fisher’s exact test.

Among participants in whom incident illness compatible with Covid-19 developed, we summarized the symptom severity score at day 14 with the median and interquartile range and assessed the distributions with a Kruskal–Wallis test. We conducted all analyses with SAS software, version 9.4 (SAS Institute), according to the intention-to-treat principle, with two-sided type I error with an alpha of 0.05. For participants with missing outcome data, we conducted a sensitivity analysis with their outcomes excluded or included as an event. Subgroups that were specified a priori included type of contact (household vs.

Health care), days from exposure to enrollment, age, and sex.Announced on May 15, Operation Warp Speed (OWS) — a partnership of the Department of Health and Human Services (HHS), the Department of Defense (DOD), and the private sector — aims to accelerate control of the Covid-19 pandemic by advancing development, manufacturing, and distribution of vaccines, therapeutics, and diagnostics. OWS is providing support to promising candidates and enabling the expeditious, parallel execution of the necessary steps toward approval or authorization of safe products by the Food and Drug Administration (FDA).The partnership grew out of an acknowledged need to fundamentally restructure the way the U.S. Government typically supports product development and vaccine distribution. The initiative was premised on setting a “stretch goal” — one that initially seemed impossible but that is becoming increasingly achievable.The concept of an integrated structure for Covid-19 countermeasure research and development across the U.S.

Government was based on experience with Zika and the Zika Leadership Group led by the National Institutes of Health (NIH) and the assistant secretary for preparedness and response (ASPR). One of us (M.S.) serves as OWS chief advisor. We are drawing on expertise from the NIH, ASPR, the Centers for Disease Control and Prevention (CDC), the Biomedical Advanced Research and Development Authority (BARDA), and the DOD, including the Joint Program Executive Office for Chemical, Biological, Radiological and Nuclear Defense and the Defense Advanced Research Projects Agency. OWS has engaged experts in all critical aspects of medical countermeasure research, development, manufacturing, and distribution to work in close coordination.The initiative set ambitious objectives.

To deliver tens of millions of doses of a SARS-CoV-2 vaccine — with demonstrated safety and efficacy, and approved or authorized by the FDA for use in the U.S. Population — beginning at the end of 2020 and to have as many as 300 million doses of such vaccines available and deployed by mid-2021. The pace and scope of such a vaccine effort are unprecedented. The 2014 West African Ebola virus epidemic spurred rapid vaccine development, but though preclinical data existed before the outbreak, a period of 12 months was required to progress from phase 1 first-in-human trials to phase 3 efficacy trials.

OWS aims to compress this time frame even further. SARS-CoV-2 vaccine development began in January, phase 1 clinical studies in March, and the first phase 3 trials in July. Our objectives are based on advances in vaccine platform technology, improved understanding of safe and efficacious vaccine design, and similarities between the SARS-CoV-1 and SARS-CoV-2 disease mechanisms.OWS’s role is to enable, accelerate, harmonize, and advise the companies developing the selected vaccines. The companies will execute the clinical or process development and manufacturing plans, while OWS leverages the full capacity of the U.S.

Government to ensure that no technical, logistic, or financial hurdles hinder vaccine development or deployment.OWS selected vaccine candidates on the basis of four criteria. We required candidates to have robust preclinical data or early-stage clinical trial data supporting their potential for clinical safety and efficacy. Candidates had to have the potential, with our acceleration support, to enter large phase 3 field efficacy trials this summer or fall (July to November 2020) and, assuming continued active transmission of the virus, to deliver efficacy outcomes by the end of 2020 or the first half of 2021. Candidates had to be based on vaccine-platform technologies permitting fast and effective manufacturing, and their developers had to demonstrate the industrial process scalability, yields, and consistency necessary to reliably produce more than 100 million doses by mid-2021.

Finally, candidates had to use one of four vaccine-platform technologies that we believe are the most likely to yield a safe and effective vaccine against Covid-19. The mRNA platform, the replication-defective live-vector platform, the recombinant-subunit-adjuvanted protein platform, or the attenuated replicating live-vector platform.OWS’s strategy relies on a few key principles. First, we sought to build a diverse project portfolio that includes two vaccine candidates based on each of the four platform technologies. Such diversification mitigates the risk of failure due to safety, efficacy, industrial manufacturability, or scheduling factors and may permit selection of the best vaccine platform for each subpopulation at risk for contracting or transmitting Covid-19, including older adults, frontline and essential workers, young adults, and pediatric populations.

In addition, advancing eight vaccines in parallel will increase the chances of delivering 300 million doses in the first half of 2021.Second, we must accelerate vaccine program development without compromising safety, efficacy, or product quality. Clinical development, process development, and manufacturing scale-up can be substantially accelerated by running all streams, fully resourced, in parallel. Doing so requires taking on substantial financial risk, as compared with the conventional sequential development approach. OWS will maximize the size of phase 3 trials (30,000 to 50,000 participants each) and optimize trial-site location by consulting daily epidemiologic and disease-forecasting models to ensure the fastest path to an efficacy readout.

Such large trials also increase the safety data set for each candidate vaccine.With heavy up-front investment, companies can conduct clinical operations and site preparation for these phase 3 efficacy trials even as they file their Investigational New Drug application (IND) for their phase 1 studies, thereby ensuring immediate initiation of phase 3 when they get a green light from the FDA. To permit appropriate comparisons among the vaccine candidates and to optimize vaccine utilization after approval by the FDA, the phase 3 trial end points and assay readouts have been harmonized through a collaborative effort involving the National Institute of Allergy and Infectious Diseases (NIAID), the Coronavirus Prevention Network, OWS, and the sponsor companies.Finally, OWS is supporting the companies financially and technically to commence process development and scale up manufacturing while their vaccines are in preclinical or very early clinical stages. To ensure that industrial processes are set, running, and validated for FDA inspection when phase 3 trials end, OWS is also supporting facility building or refurbishing, equipment fitting, staff hiring and training, raw-material sourcing, technology transfer and validation, bulk product processing into vials, and acquisition of ample vials, syringes, and needles for each vaccine candidate. We aim to have stockpiled, at OWS’s expense, a few tens of millions of vaccine doses that could be swiftly deployed once FDA approval is obtained.This strategy aims to accelerate vaccine development without curtailing the critical steps required by sound science and regulatory standards.

The FDA recently reissued guidance and standards that will be used to assess each vaccine for a Biologics License Application (BLA). Alternatively, the agency could decide to issue an Emergency Use Authorization to permit vaccine administration before all BLA procedures are completed.Of the eight vaccines in OWS’s portfolio, six have been announced and partnerships executed with the companies. Moderna and Pfizer/BioNTech (both mRNA), AstraZeneca and Janssen (both replication-defective live-vector), and Novavax and Sanofi/GSK (both recombinant-subunit-adjuvanted protein). These candidates cover three of the four platform technologies and are currently in clinical trials.

The remaining two candidates will enter trials soon.Moderna developed its RNA vaccine in collaboration with the NIAID, began its phase 1 trial in March, recently published encouraging safety and immunogenicity data,1 and entered phase 3 on July 27. Pfizer and BioNTech’s RNA vaccine also produced encouraging phase 1 results2 and started its phase 3 trial on July 27. The ChAdOx replication-defective live-vector vaccine developed by AstraZeneca and Oxford University is in phase 3 trials in the United Kingdom, Brazil, and South Africa, and it should enter U.S. Phase 3 trials in August.3 The Janssen Ad26 Covid-19 replication-defective live-vector vaccine has demonstrated excellent protection in nonhuman primate models and began its U.S.

Phase 1 trial on July 27. It should be in phase 3 trials in mid-September. Novavax completed a phase 1 trial of its recombinant-subunit-adjuvanted protein vaccine in Australia and should enter phase 3 trials in the United States by the end of September.4 Sanofi/GSK is completing preclinical development steps and plans to commence a phase 1 trial in early September and to be well into phase 3 by year’s end.5On the process-development front, the RNA vaccines are already being manufactured at scale. The other candidates are well advanced in their scale-up development, and manufacturing sites are being refurbished.While development and manufacturing proceed, the HHS–DOD partnership is laying the groundwork for vaccine distribution, subpopulation prioritization, financing, and logistic support.

We are working with bioethicists and experts from the NIH, the CDC, BARDA, and the Centers for Medicare and Medicaid Services to address these critical issues. We will receive recommendations from the CDC Advisory Committee on Immunization Practices, and we are working to ensure that the most vulnerable and at-risk persons will receive vaccine doses once they are ready. Prioritization will also depend on the relative performance of each vaccine and its suitability for particular populations. Because some technologies have limited previous data on safety in humans, the long-term safety of these vaccines will be carefully assessed using pharmacovigilance surveillance strategies.No scientific enterprise could guarantee success by January 2021, but the strategic decisions and choices we’ve made, the support the government has provided, and the accomplishments to date make us optimistic that we will succeed in this unprecedented endeavor..

Are acyclovir and valacyclovir the same

First-of-its-kind study, based on a mouse model, finds living in a polluted environment could be comparable to eating a high-fat diet, leading to a pre-diabetic are acyclovir and valacyclovir the same state CLEVELAND—Air pollution is the world’s leading environmental risk factor, and causes more than nine million deaths per year. New research published in the Journal of Clinical Investigation shows air pollution may play a role in the development of cardiometabolic diseases, such as diabetes. Importantly, the effects are acyclovir and valacyclovir the same were reversible with cessation of exposure. Researchers found that air pollution was a “risk factor for a risk factor” that contributed to the common soil of other fatal problems like heart attack and stroke. Similar to how an unhealthy diet and lack of exercise can lead to disease, exposure to air pollution could be added to this risk factor list as well.

“In this study, we created an environment that mimicked a polluted day in New Delhi or Beijing,” said Sanjay Rajagopalan, MD, are acyclovir and valacyclovir the same first author on the study, Chief of Cardiovascular Medicine at University Hospitals Harrington Heart and Vascular Institute, and Director of the Case Western Reserve University Cardiovascular Research Institute. €œWe concentrated fine particles of air pollution, called PM2.5 (particulate matter component <. 2.5 microns) are acyclovir and valacyclovir the same. Concentrated particles like this develop from human impact on the environment, such as automobile exhaust, power generation and other fossil fuels.” These particles have been strongly connected to risk factors for disease. For example, cardiovascular effects of air pollution can lead to heart attack and stroke.

The research team has shown exposure to air pollution can increase the are acyclovir and valacyclovir the same likelihood of the same risk factors that lead to heart disease, such as insulin resistance and type 2 diabetes. In the mouse model study, three groups were observed. A control group receiving clean filtered air, a group exposed to polluted air for 24 weeks, and a group fed a high-fat diet. Interestingly, the researchers found that being are acyclovir and valacyclovir the same exposed to air pollution was comparable to eating a high-fat diet. Both the air pollution and high-fat diet groups showed insulin resistance and abnormal metabolism – just like one would see in a pre-diabetic state.

These changes were associated with changes in the epigenome, a layer of control that can masterfully turn on and turn off thousands of genes, representing a critical buffer in response to environmental factors are acyclovir and valacyclovir the same. This study is the first-of-its-kind to compare genome-wide epigenetic changes in response to air pollution, compare and contrast these changes with that of eating an unhealthy diet, and examine the impact of air pollution cessation on these changes.“The good news is that these effects were reversible, at least in our experiments” added Dr. Rajagopalan. €œOnce the air pollution was removed from the environment, are acyclovir and valacyclovir the same the mice appeared healthier and the pre-diabetic state seemed to reverse.” Dr. Rajagopalan explains that if you live in a densely polluted environment, taking actions such as wearing an N95 mask, using portable indoor air cleaners, utilizing air conditioning, closing car windows while commuting, and changing car air filters frequently could all be helpful in staying healthy and limiting air pollution exposure.Next steps in this research involve meeting with a panel of experts, as well as the National Institutes of Health, to discuss conducting clinical trials that compare heart health and the level of air pollution in the environment.

For example, if someone has a heart attack, should they be wearing an N95 mask or using a portable air filter at home during recovery?. Dr are acyclovir and valacyclovir the same. Rajagopalan and his team believe that it is important to address the environment as a population health risk factor and continue to diligently research these issues. The authors also note that these findings should encourage policymakers are acyclovir and valacyclovir the same to enact measures aimed at reducing air pollution.Shyam Biswal, PhD, Professor in the Department of Environmental Health and Engineering at Johns Hopkins University School of Public Health, is the joint senior author on the study.

Prenatal depression is linked to behavioural and developmental issues in children as well as an increased risk for depression as young adults. But how prenatal depression leads to these changes remains unclear. UCalgary researcher Dr. Catherine Lebel, PhD, is helping understand what may be happening in the developing brains of these children. The research team has shown that young children whose mothers experienced more numerous symptoms of depression in pregnancy have weakened connectivity in brain pathways involved in emotion.

These structural changes can be related to increased hyperactivity and aggression in boys.

First-of-its-kind study, based on a mouse model, finds living in a polluted environment could be comparable to eating a high-fat buy acyclovir online canada diet, leading to a pre-diabetic state CLEVELAND—Air pollution is the world’s leading environmental risk factor, and causes more than nine million deaths per year. New research published in the Journal of Clinical Investigation shows air pollution may play a role in the development of cardiometabolic diseases, such as diabetes. Importantly, the effects were reversible with buy acyclovir online canada cessation of exposure. Researchers found that air pollution was a “risk factor for a risk factor” that contributed to the common soil of other fatal problems like heart attack and stroke. Similar to how an unhealthy diet and lack of exercise can lead to disease, exposure to air pollution could be added to this risk factor list as well.

“In this study, we created an environment that mimicked a polluted day in New Delhi or Beijing,” said Sanjay Rajagopalan, MD, first author on the study, Chief of Cardiovascular Medicine at University Hospitals buy acyclovir online canada Harrington Heart and Vascular Institute, and Director of the Case Western Reserve University Cardiovascular Research Institute. €œWe concentrated fine particles of air pollution, called PM2.5 (particulate matter component <. 2.5 microns) buy acyclovir online canada. Concentrated particles like this develop from human impact on the environment, such as automobile exhaust, power generation and other fossil fuels.” These particles have been strongly connected to risk factors for disease. For example, cardiovascular effects of air pollution can lead to heart attack and stroke.

The research team has shown exposure to air pollution can increase the likelihood of the same risk factors buy acyclovir online canada that lead to heart disease, such as insulin resistance and type 2 diabetes. In the mouse model study, three groups were observed. A control group receiving clean filtered air, a group exposed to polluted air for 24 weeks, and a group fed a high-fat diet. Interestingly, the researchers found that being exposed to air pollution was comparable to eating a high-fat diet buy acyclovir online canada. Both the air pollution and high-fat diet groups showed insulin resistance and abnormal metabolism – just like one would see in a pre-diabetic state.

These changes were associated with changes in the epigenome, a layer of control that can buy acyclovir online canada masterfully turn on and turn off thousands of genes, representing a critical buffer in response to environmental factors. This study is the first-of-its-kind to compare genome-wide epigenetic changes in response to air pollution, compare and contrast these changes with that of eating an unhealthy diet, and examine the impact of air pollution cessation on these changes.“The good news is that these effects were reversible, at least in our experiments” added Dr. Rajagopalan. €œOnce the air pollution was removed from the environment, the buy acyclovir online canada mice appeared healthier and the pre-diabetic state seemed to reverse.” Dr. Rajagopalan explains that if you live in a densely polluted environment, taking actions such as wearing an N95 mask, using portable indoor air cleaners, utilizing air conditioning, closing car windows while commuting, and changing car air filters frequently could all be helpful in staying healthy and limiting air pollution exposure.Next steps in this research involve meeting with a panel of experts, as well as the National Institutes of Health, to discuss conducting clinical trials that compare heart health and the level of air pollution in the environment.

For example, if someone has a heart attack, should they be wearing an N95 mask or using a portable air filter at home during recovery?. Dr buy acyclovir online canada. Rajagopalan and his team believe that it is important to address the environment as a population health risk factor and continue to diligently research these issues. The authors also note that these findings should encourage buy acyclovir online canada policymakers to enact measures aimed at reducing air pollution.Shyam Biswal, PhD, Professor in the Department of Environmental Health and Engineering at Johns Hopkins University School of Public Health, is the joint senior author on the study.

Prenatal depression is linked to behavioural and developmental issues in children as well as an increased risk for depression as young adults. But how prenatal depression leads to these changes remains unclear. UCalgary researcher Dr. Catherine Lebel, PhD, is helping understand what may be happening in the developing brains of these children. The research team has shown that young children whose mothers experienced more numerous symptoms of depression in pregnancy have weakened connectivity in brain pathways involved in emotion.

These structural changes can be related to increased hyperactivity and aggression in boys.

CCCA predominantly affects black women and is the most common form of permanent alopecia in how to order acyclovir online this population. The excess scar tissue that forms as a result of this type of hair loss may also explain the higher risk for uterine fibroids, which are characterized by fibrous growths in the lining of the womb.

Crystal Aguh, M.D., assistant professor of dermatology at the Johns Hopkins University School of Medicine, says the scarring associated with CCCA is similar to the scarring associated with excess fibrous tissue elsewhere in the body, a situation that may explain why women with this type of hair loss are at a higher risk for fibroids.People of African descent, she notes, are more prone to develop how to order acyclovir online other disorders of abnormal scarring, termed fibroproliferative disorders, such as keloids (a type of raised scar after trauma), scleroderma (an autoimmune disorder marked by thickening of the skin as well as internal organs), some types of lupus and clogged arteries. During a four-year period from 2013-2017, the researchers analyzed patient data from the Johns Hopkins electronic medical record system (Epic) of 487,104 black women ages 18 and over. The prevalence of those how to order acyclovir online with fibroids was compared in patients with and without CCCA. Overall, the researchers found that 13.9 percent of women with CCCA also had a history of uterine fibroids compared to only 3.3 percent of black women without the condition.

In absolute numbers, out of the 486,000 women who were reviewed, 16,212 had fibroids.Within that population, 447 had CCCA, of which 62 had fibroids. The findings translate to a fivefold increased risk of uterine how to order acyclovir online fibroids in women with CCCA, compared to age, sex and race matched controls. Aguh cautions that their study does not suggest any cause and effect relationship, or prove a common cause for both conditions. €œThe cause of the link between the two conditions remains how to order acyclovir online unclear,” she says.

However, the association was strong enough, she adds, to recommend that physicians and patients be made aware of it. Women with this how to order acyclovir online type of scarring alopecia should be screened not only for fibroids, but also for other disorders associated with excess fibrous tissue, Aguh says. An estimated 70 percent of white women and between 80 and 90 percent of African-American women will develop fibroids by age 50, according to the NIH, and while CCCA is likely underdiagnosed, some estimates report a prevalence of rates as high as 17 percent of black women having this condition.

The New England Journal of Medicine Share Fast Facts This study how to order acyclovir online clears up how big an effect the mutational burden has on outcomes to immune checkpoint inhibitors across many different cancer types. - Click to Tweet The number of mutations in a tumor’s DNA is a good predictor of whether it will respond to a class of cancer immunotherapy drugs known as checkpoint inhibitors.

- Click to Tweet The “mutational burden,” or the number of mutations present in a tumor’s DNA, is a good predictor of whether that cancer type will respond to a class of cancer how to order acyclovir online immunotherapy drugs known as checkpoint inhibitors, a new study led by Johns Hopkins Kimmel Cancer Center researchers shows. The finding, published in the Dec. 21 New England Journal of Medicine, could be used to guide future clinical trials for these how to order acyclovir online drugs. Checkpoint inhibitors are a relatively new class of drug that helps the immune system recognize cancer by interfering with mechanisms cancer cells use to hide from immune cells.

As a result, the drugs cause the immune system to fight cancer in the same way that it would fight an infection. These medicines have had remarkable success in treating how to order acyclovir online some types of cancers that historically have had poor prognoses, such as advanced melanoma and lung cancer. However, these therapies have had little effect on other deadly cancer types, such as pancreatic cancer and glioblastoma. The mutational burden how to order acyclovir online of certain tumor types has previously been proposed as an explanation for why certain cancers respond better than others to immune checkpoint inhibitors says study leader Mark Yarchoan, M.D., chief medical oncology fellow.

Work by Dung Le, M.D., associate professor of oncology, and other researchers at the Johns Hopkins Kimmel Cancer Center and its Bloomberg~Kimmel Cancer Institute for Cancer Immunotherapy showed that colon cancers that carry a high number of mutations are more likely to respond to checkpoint inhibitors than those that have fewer mutations. However, exactly how how to order acyclovir online big an effect the mutational burden has on outcomes to immune checkpoint inhibitors across many different cancer types was unclear. To investigate this question, Yarchoan and colleagues Alexander Hopkins, Ph.D., research fellow, and Elizabeth Jaffee, M.D., co-director of the Skip Viragh Center for Pancreas Cancer Clinical Research and Patient Care and associate director of the Bloomberg~Kimmel Institute, combed the medical literature for the results of clinical trials using checkpoint inhibitors on various different types of cancer. They combined these findings with data on how to order acyclovir online the mutational burden of thousands of tumor samples from patients with different tumor types.

Analyzing 27 different cancer types for which both pieces of information were available, the researchers found a strong correlation. The higher a cancer type’s mutational burden tends to be, the more likely it is to respond to checkpoint inhibitors. More than half how to order acyclovir online of the differences in how well cancers responded to immune checkpoint inhibitors could be explained by the mutational burden of that cancer. €œThe idea that a tumor type with more mutations might be easier to treat than one with fewer sounds a little counterintuitive.

It’s one of those things that doesn’t sound right how to order acyclovir online when you hear it,” says Hopkins. €œBut with immunotherapy, the more mutations you have, the more chances the immune system has to recognize the tumor.” Although this finding held true for the vast majority of cancer types they studied, there were some outliers in their analysis, says Yarchoan. For example, how to order acyclovir online Merkel cell cancer, a rare and highly aggressive skin cancer, tends to have a moderate number of mutations yet responds extremely well to checkpoint inhibitors. However, he explains, this cancer type is often caused by a virus, which seems to encourage a strong immune response despite the cancer’s lower mutational burden.

In contrast, the most common type of colorectal cancer has moderate mutational burden, yet responds poorly to checkpoint inhibitors for reasons that are still unclear. Yarchoan notes how to order acyclovir online that these findings could help guide clinical trials to test checkpoint inhibitors on cancer types for which these drugs haven’t yet been tried. Future studies might also focus on finding ways to prompt cancers with low mutational burdens to behave like those with higher mutational burdens so that they will respond better to these therapies. He and his colleagues plan to extend this how to order acyclovir online line of research by investigating whether mutational burden might be a good predictor of whether cancers in individual patients might respond well to this class of immunotherapy drugs.

Does acyclovir cream work for cold sores

Imagine being does acyclovir cream work for cold sores browse around this web-site infected with a deadly virus that makes you impervious to pain. By the time you realize you are infected, it’s already too does acyclovir cream work for cold sores late. You have spread it far and wide. Recent findings in my lab suggest that this scenario may be one reason that people infected with SARS-CoV-2, the virus causing COVID-19, may be spreading the disease without knowing it.Most accounts to date have focused on how the virus invades cells via the ACE2 protein on the surface of many cells does acyclovir cream work for cold sores. But recent studies, which have not yet been peer-reviewed, suggest there is another route to infecting the cell that enables it to infect the nervous system.

This led my research group to uncover a link between a particular cellular protein and pain – an interaction that is disrupted by the does acyclovir cream work for cold sores coronavirus. Our research has now been peer-reviewed and will be published in the journal PAIN.I am a scientist who studies how proteins on cells trigger pain signals that are transmitted through the body to the brain. When these proteins are active, the nerve cells are does acyclovir cream work for cold sores talking to each other. This conversation occurs at deafening levels in chronic pain. So by studying what causes the excitability of nerve cells to change, we can begin to unravel how chronic pain becomes established does acyclovir cream work for cold sores.

This also allows us to design ways to mute this conversation to blunt or stop chronic pain.My laboratory has a longstanding interest in designing nonopioid-based alternatives for pain management.Linking SARS-CoV-2 and painYou might be wondering how my lab began to probe the connection between SARS-CoV-2 and pain. We were inspired by two preliminary reports that appeared on the preprint server BioRxiv that showed that the infamous spike proteins on the surface of the SARS-CoV-2 virus bound to does acyclovir cream work for cold sores a protein called neuropilin-1. This means that the virus can also use this protein to invade nerve cells as well as through the ACE2 protein.For the past year, some six months before the pandemic took hold, my colleagues and I had been studying the role of neuropilin-1 in the context of pain perception. Because neuropilin-1, like the ACE2 receptor, allowed spike to enter the cells, we wondered if this alternate gateway could also be related does acyclovir cream work for cold sores to pain.Under normal circumstances, the neuropilin-1 protein controls the growth of blood vessels, and as well as the growth and survival of neurons.However, when neuropilin-1 binds to a naturally occurring protein called called Vascular endothelial growth factor A (VEGF-A), this triggers pain signals. This signal is transmitted via the spinal cord into higher brain centers to cause the sensation we all know as pain.Staring at this jigsaw puzzle – neuropilin-1 and VEGF-A and neuropilin and spike – we wondered if there was a link between spike and pain.Previous research has shown a link between VEGF-A and pain.

For people with osteoarthritis, for instance, studies have shown that increased activity of the VEGF gene in fluids lubricating joints, like the knee, is associated with higher pain scores.Although activity of the neuropilin-1 gene is higher in biological samples from COVID-19 patients compared to healthy controls and activity of the neuropilin-1 gene is increased in pain-sensing neurons in an animal model of chronic pain, the role of neuropilin-1 in pain has never been explored until now.In in vitro studies done in my lab using nerve cells, we showed that when spike binds to neuropilin-1 it decreases pain signaling, which suggests does acyclovir cream work for cold sores that in a living animal it would also have a pain-dulling effect.When the spike protein binds to the neuropilin-1 protein, it blocks the VEGF-A protein from binding and thus hijack’s a cell’s pain circuitry. This binding suppresses the excitability of pain neurons, leading to lower sensitivity to pain.Crystal https://www.cityreal.lv/buy-acyclovir-online/ structure of neuropilin-1 b1 domain (white surface with binding site in red) showing binding of VEGF-A (left), spike protein (middle), and the neuropilin-1 inhibitor EG00229 (right). (Credit. Dr. Samantha Perez-Miller, CC BY-SA)From the COVID-19 fog a new pain target emergesIf our finding that the new coronavirus is attacking cells through a protein associated with pain and disabling the protein can be confirmed in humans, it may provide a new pathway for drug development to treat COVID-19.A small molecule, called EG00229, targeting neuropilin-1 had been reported in a 2018 study.

This molecule binds to the same region of the neuropilin-1 protein as the viral spike protein and VEGF-A. So I and my colleagues asked if this molecule was able to block pain. It did, during pain simulations in rats. Our data reaffirmed the notion of neuropilin-1 as a new player in pain signaling.There is precedence for targeting the neuropilin-1 protein for cancer treatment. For example, a Phase 1a clinical trial of an antibody called MNRP1685A (known under the product name Vesencumab) that recognizes and binds to neuropilin-1 and blocks VEGF-binding.

This was mostly well tolerated in cancer patients, but it caused pain rather than blocking it.Our studies identify a different approach because we targeted blocking the pain-triggering VEGF-A protein, which then resulted in pain relief. So our preclinical work described here provides a rationale for targeting the VEGF-A/NRP-1 pro-pain signaling system in future clinical trials.Analysis of the structure of the neuropilin-1 receptor protein may allow design of drugs targeting this critical site which also controls axon growth, cell survival – in addition to pain relief.For instance, these neuropilin-1 receptor targeted drugs could potentially block viral infection. The testing of several candidate compounds, some of them on the FDA’s generally regarded as safe list, is currently underway by my group.Sneaky virus, fooling people into believing that they do not have COVID-19. But, ironically, it may be gifting us with the knowledge of a new protein, critical for pain. Two roads emerge in the forest ahead.

(1) block neuropilin-1 to limit SARS-CoV-2 entry, and (2) block neuropilin-1 to block pain.Rajesh Khanna is a Professor of Pharmacology, University of Arizona. This article originally appeared on The Conversation under a Creative Commons license. Read the original here..

Recent findings in my lab suggest that this scenario may be one reason that people buy acyclovir online canada infected with SARS-CoV-2, the virus causing COVID-19, may be spreading the disease without knowing it.Most accounts to date have focused on how the virus invades cells via the ACE2 protein on the surface of many cells.

But recent studies, which have not yet been peer-reviewed, suggest there is another route to infecting the cell that enables it to infect the nervous system. This led my buy acyclovir online canada research group to uncover a link between a particular cellular protein and pain – an interaction that is disrupted by the coronavirus. Our research has now been peer-reviewed and will be published in the journal PAIN.I am a scientist who studies how proteins on cells trigger pain signals that are transmitted through the body to the brain. When these proteins are active, the nerve cells are talking to each buy acyclovir online canada other.

This conversation occurs at deafening levels in chronic pain. So by buy acyclovir online canada studying what causes the excitability of nerve cells to change, we can begin to unravel how chronic pain becomes established. This also allows us to design ways to mute this conversation to blunt or stop chronic pain.My laboratory has a longstanding interest in designing nonopioid-based alternatives for pain management.Linking SARS-CoV-2 and painYou might be wondering how my lab began to probe the connection between SARS-CoV-2 and pain. We were inspired by two preliminary reports that appeared on the preprint server buy acyclovir online canada BioRxiv that showed that the infamous spike proteins on the surface of the SARS-CoV-2 virus bound to a protein called neuropilin-1.

This means that the virus can also use this protein to invade nerve cells as well as through the ACE2 protein.For the past year, some six months before the pandemic took hold, my colleagues and I had been studying the role of neuropilin-1 in the context of pain perception. Because neuropilin-1, like the ACE2 receptor, allowed spike to enter the cells, we wondered if this alternate gateway could also be related to pain.Under buy acyclovir online canada normal circumstances, the neuropilin-1 protein controls the growth of blood vessels, and as well as the growth and survival of neurons.However, when neuropilin-1 binds to a naturally occurring protein called called Vascular endothelial growth factor A (VEGF-A), this triggers pain signals. This signal is transmitted via the spinal cord into higher brain centers to cause the sensation we all know as pain.Staring at this jigsaw puzzle – neuropilin-1 and VEGF-A and neuropilin and spike – we wondered if there was a link between spike and pain.Previous research has shown a link between VEGF-A and pain. For people with osteoarthritis, for instance, studies have shown that increased activity of the VEGF gene in fluids lubricating joints, like the knee, is associated with higher pain scores.Although activity of the neuropilin-1 gene is higher in biological samples from COVID-19 patients compared to healthy controls and activity of the neuropilin-1 gene is increased in pain-sensing neurons in an animal model of chronic pain, the role of neuropilin-1 in pain has never been explored until now.In in vitro studies done in my lab using nerve cells, we showed that when spike binds to neuropilin-1 it decreases pain buy acyclovir online canada signaling, which suggests that in a living animal it would also have a pain-dulling effect.When the spike protein binds to the neuropilin-1 protein, it blocks the VEGF-A protein from binding and thus hijack’s a cell’s pain circuitry.

This binding suppresses the excitability of pain neurons, leading to lower sensitivity to pain.Crystal structure of neuropilin-1 b1 domain (white surface with binding site in red) showing binding of VEGF-A (left), spike protein (middle), and the neuropilin-1 inhibitor EG00229 (right). (Credit. Dr. Samantha Perez-Miller, CC BY-SA)From the COVID-19 fog a new pain target emergesIf our finding that the new coronavirus is attacking cells through a protein associated with pain and disabling the protein can be confirmed in humans, it may provide a new pathway for drug development to treat COVID-19.A small molecule, called EG00229, targeting neuropilin-1 had been reported in a 2018 study.

This molecule binds to the same region of the neuropilin-1 protein as the viral spike protein and VEGF-A. So I and my colleagues asked if this molecule was able to block pain. It did, during pain simulations in rats. Our data reaffirmed the notion of neuropilin-1 as a new player in pain signaling.There is precedence for targeting the neuropilin-1 protein for cancer treatment.

For example, a Phase 1a clinical trial of an antibody called MNRP1685A (known under the product name Vesencumab) that recognizes and binds to neuropilin-1 and blocks VEGF-binding. This was mostly well tolerated in cancer patients, but it caused pain rather than blocking it.Our studies identify a different approach because we targeted blocking the pain-triggering VEGF-A protein, which then resulted in pain relief. So our preclinical work described here provides a rationale for targeting the VEGF-A/NRP-1 pro-pain signaling system in future clinical trials.Analysis of the structure of the neuropilin-1 receptor protein may allow design of drugs targeting this critical site which also controls axon growth, cell survival – in addition to pain relief.For instance, these neuropilin-1 receptor targeted drugs could potentially block viral infection. The testing of several candidate compounds, some of them on the FDA’s generally regarded as safe list, is currently underway by my group.Sneaky virus, fooling people into believing that they do not have COVID-19.

But, ironically, it may be gifting us with the knowledge of a new protein, critical for pain. Two roads emerge in the forest ahead. (1) block neuropilin-1 to limit SARS-CoV-2 entry, and (2) block neuropilin-1 to block pain.Rajesh Khanna is a Professor of Pharmacology, University of Arizona.
