Safety, Tolerability, and Efficacy of Anti-Spike (S) SARS-CoV-2 Monoclonal Antibodies for Hospitalized Adult Patients With COVID-19

Summary

The primary objectives are: Pooled Phase 3 (Cohort 1) and Phase 2 (Cohort 1A) * To evaluate the virologic efficacy of REGN10933+REGN10987 compared to placebo in reducing viral load of SARS-CoV-2 * To evaluate the clinical efficacy of REGN10933+REGN10987 compared to placebo, as measured by death or mechanical ventilation Phase 1/2 (Cohort 1) * To exclude futility of REGN10933+REGN10987 compared to placebo, as measured by death or mechanical ventilation * To evaluate the safety and tolerability of REGN10933+REGN10987 compared to placebo
