Pharmacokinetic Study of Cabotegravir Long-acting in Healthy Adult Volunteers

Study Overview
=================
Brief Summary
-----------------
Cabotegravir (CAB) long-acting (LA) is a promising candidate for human immunodeficiency virus (HIV) pre exposure prophylaxis (PrEP) due to its potent antiretroviral activity and infrequent dosing requirements. Currently, the CAB concentrations achieved in the anatomical sites associated with sexual HIV transmission following the proposed 600 milligram (mg) intramuscular (IM) PrEP dose are unknown. These data will enhance our understanding of CAB distribution to the anatomical mucosal tissue believed to be relevant to sexual HIV-1 transmission and supplement the data to support future PrEP clinical trial development. The primary objective is to determine the PK concentrations of CAB following LA administration in plasma and in vaginal tissue (VT), cervical tissue (CT), and cervicovaginal fluid (CVF) in healthy women and in rectal tissue (RT) and rectal fluid (RF) in healthy men and women following a single 600 mg IM dose. This will be a Phase 1, open label study in healthy subjects to assess the pharmacokinetics of CAB LA in the plasma and mucosal locations associated with sexual HIV-1 transmission: VT, CT, CVF, RT and RF. The study will consist of a screening period, a 28-day oral lead-in phase at a dose of 30 mg per day followed by a 14-42 day washout period, and a single dose of CAB LA 600 mg as an IM (intragluteal) injection with compartmental pharmacokinetic (PK) sampling for up to 12 weeks. Subjects will return for safety assessments and plasma PK sampling at Week 24 and Week 36 post-injection and undergo a follow-up/withdrawal visit at Week 52 post-injection.
