SARS-CoV-2 Infection Clinical Trial
Official title:
A Phase II/III Randomized, Double-Blind, Placebo-Controlled Trial to Evaluate the Efficacy and Safety of Azvudine in Preventing SARS-Cov-2 Infection in Household Contacts of Individuals Infected With SARS-CoV-2
A Phase II/III Randomized, Double-Blind, Placebo-Controlled Trial to Evaluate the Efficacy and Safety of Azvudine in Preventing SARS-Cov-2 Infection in Household Contacts of Individuals Infected with SARS-CoV-2
The study has two parts: Part 1 is a multicentre, randomized, double-blind, placebo-controlled phase II clinical study to evaluate the efficacy and safety of Azvudine versus placebo in preventing SARS-CoV-2 infection in household contacts with SARS-CoV-2 infection individuals. The population of part 1 will consist of approximately 450 adults with household contact exposure to individuals with a confirmed SARS-CoV-2 infection.A phase III study will be further conducted if any of the treatment groups reduce SARS-CoV-2 infection rate (Relative risk reduction) > 50% compared with the placebo group. Part 2 is a multicentre, randomized, double-blind, placebo-controlled phase III clinical study. The subject sample size will be calculated based on the results of the Phase II trial. Phase II and phase III studies have the same objectives and primary/secondary end points. The primary endpoint is the proportion of subjects with positive SARS-CoV-2 RT-PCR assay in 7 days. Nasopharyngeal swabs will be collected at D2, D4, D7, D10, and D14 by RT-PCR to confirm SARS-CoV-2 infection. ;
