COVID-19 Study Assessing the Virologic Efficacy of REGN10933+REGN10987 Across Different Dose Regimens in Adult Outpatients With SARS-CoV-2 Infection
Summary
The primary objective of the study is to assess the virologic efficacy of REGN10933+REGN10987 across different intravenous and subcutaneous doses compared to placebo. The secondary objectives of the study are: * To evaluate additional indicators of virologic efficacy of REGN10933+REGN10987 compared to placebo * To evaluate the safety and tolerability of REGN10933+REGN10987 compared to placebo * To assess the concentrations of REGN10933 and REGN10987 in serum over time * To assess the immunogenicity of REGN10933 and REGN10987
