Two randomized, controlled Phase 3 clinical trials have begun evaluating investigational monoclonal antibodies for their safety and efficacy in treating people hospitalized with moderate COVID-19. The trials are part of the ACTIV-3 master protocol, which has an adaptive design allowing investigators to add new sub-studies of additional investigational agents. ACTIV-3 is sponsored by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health.
One sub-study is evaluating VIR-7831, a monoclonal antibody developed through a partnership between GlaxoSmithKline plc (Brentford, United Kingdom) and Vir Biotechnology, Inc. (San Francisco). The other sub-study is evaluating the combination of BRII-196 and BRII-198, two neutralizing monoclonal
