Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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
