Description

Summary

The primary objective of this study is to evaluate the efficacy of lenacapavir (LEN) in preventing the risk of human immunodeficiency virus (HIV) - 1 infection relative to the background HIV-1 incidence rate. The study will be conducted in 2 parts: a cross-sectional study (Incidence Phase) and a double-blind, randomized study (Randomized Phase). The Incidence Phase will include initial assessments that will provide an estimate of the concurrent background HIV-1 incidence rate. The Randomized Phase of the study will have a Blinded Phase, a LEN Open-label Extension (OLE) Phase, and a pharmacokinetic (PK) Tail Phase. The primary objective for the Incidence Phase of this study is to estimate the HIV-1 background incidence rate. The primary objective of the Randomized Blinded Phase of this study is to evaluate the efficacy of lenacapavir for HIV-1 pre-exposure prophylaxis (PrEP) in cisgender men (CGM), transgender women (TGW), transgender men (TGM), and gender nonbinary people (GNB) ≥ 16 years of age who have condomless receptive anal sex with partners assigned male at birth and are at risk for HIV-1 infection.
