Clinical Trial Summary

A Global, Multi-center, Randomized, Double-Blind, Placebo-Controlled, Phase III Clinical Study to Evaluate the Efficacy, Safety, and Immunogenicity of Recombinant SARS-CoV-2 Fusion Protein Vaccine (V-01) in Adults Aged 18 Years and Older

Description:

This is a global, multicenter, randomized, double-blind, placebo-controlled, parallel-group phase III clinical study. Approximately 22,500 participants aged 18 years and older will be enrolled in this study to evaluate the efficacy, safety and immunogenicity of recombinant SARS-CoV-2 fusion protein vaccine (code: V-01, hereinafter referred to as V-01). The eligible participants will be randomized in a 2:1 ratio into investigational vaccine group (V-01) and placebo group, with random stratification factors including 1) age (18-59 years vs ≥60 years); 2) gender (male vs female); and 3) whether or not being enrolled into immunogenicity subgroup (yes vs no). The participants will receive investigational vaccine V-01 or placebo on two doses schedule (one dose each on day 0 and 21, with +7 days' time window for the second dose).
