Study to Evaluate the Safety and Efficacy of Teropavimab and Zinlirvimab in Combination With Lenacapavir in Virologically Suppressed Adults With HIV-1 Infection

Summary

The primary objective of this study is to evaluate the safety and tolerability of a combination of the broadly neutralizing antibodies (bNAbs) teropavimab (formerly GS-5423) and zinlirvimab (formerly GS-2872) in combination with the HIV capsid inhibitor lenacapavir (LEN).
