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

• Phase: Phase 2
• Accepts Healthy Volunteers?: No
