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

Summary

Phase 1 * To evaluate the safety and tolerability of REGN10933+REGN10987 compared to placebo * To evaluate the virologic efficacy of REGN10933+REGN10987 compared to placebo in reducing viral load of SARS-CoV-2 Phase 2 • To evaluate the virologic efficacy of REGN10933+REGN10987 compared to placebo in reducing viral load of SARS-CoV-2 Phase 3 * Cohort 1 (≥18 Years Old, Not Pregnant at Randomization) • To evaluate the clinical efficacy of REGN10933+REGN10987 compared to placebo as measured by COVID-19-related hospitalizations or all-cause death * Cohort 2 (\<18 Years Old, Not Pregnant at Randomization) * To evaluate the safety and tolerability of REGN10933+REGN10987 compared to placebo * To further characterize the concentrations of REGN10933 and REGN10987 in serum over time * Cohort 3 (Pregnant at Randomization) • To evaluate the safety and tolerability of REGN10933+REGN10987
