The placebo-controlled trials will be conducted at multiple sites. The first two adaptive Phase 1/2/3 studies are evaluating REGN-COV2 as a treatment for hospitalized and non-hospitalized patients with COVID-19. The Phase 1 portion will focus on virologic and safety endpoints, and the Phase 2 portion will focus on virologic and clinical endpoints. Data from the Phase 1 and Phase 2 studies will be used to refine the endpoints and determine size for the Phase 3 studies.
