A Phase I Randomized, Placebo-controlled, Double-blind Study to Assess Safety, Pharmacokinetics, and Modeled Pharmacodynamics of a Vaginal Insert Containing Tenofovir Alafenamide and Elvitegravir
Brief description: MATRIX-001 will examine the safety, PK, modeled PD, and acceptability of inserts containing the combination of TAF and EVG applied vaginally, daily for 3 days, then every other day for 14 days. The inserts are ultimately intended to be the basis of an event-driven, on-demand method for prevention of HIV and HSV sexual infection.
Detailed description: Participants will be enrolled across three sites, in USA, Kenya, and South Africa, approximately 20 per site. Participants will be randomized (1:1) to receive either a placebo or TAF/EVG vaginal insert as well as be randomized (1:1:1) to 3 different tissue sampling time points post-treatment (24hr, 48hr and 72hr after the last dose). Participants will be asked to complete 8 study visits with clinical and behavioral evaluations, and a subset will complete an in-depth interview to assess acceptability of vaginal insert use.
