Maraviroc for HIV/AIDS (ENLIGHTEN Trial)
ENLIGHTEN Trial Summary
Purpose: Perform a 3-phase (single dose, multi dose, dose proportionality) study in healthy volunteers using daily tenofovir+emtricitabine, dolutegravir, and maraviroc dosing to quantify intra- and inter-subject variability and dose proportionality. The influence of covariates on ARV hair distribution (e.g., hair growth rate, race, hair color, hair treatment) will also be measured. Using both population PK modeling and physiologic based PK (PBPK) approaches, a statistical model to quantify ARV adherence patterns based on signal intensity/pattern will be developed. Participants: Healthy volunteers, aged 18 to 70 years of age, inclusive on the date of screening, with an intact gastrointestinal system and at least 1cm caput hair. Procedures (methods): Participants will be sequentially assigned to enroll in a dosing arm, beginning with maraviroc (MVC), then dolutegravir (DTG), and ending with tenofovir/emtricitabine (TFV/FTC). All participants will take a single observed dose of study product in Phase 1, with blood and hair samples obtained on Days 3, 7, 14, 21 and 28 days post-dose. In Phase 2, all participants take 28 days straight of daily dosing, observed, of the same study product. Blood and hair samples obtained on the same days post-dose. In Phase 3, participants will be randomized to stop their drug, or decrease dosing to one or three doses weekly. Hair and blood samples will again be obtained on the same days post-dose. All participants will complete a follow-up safety visit with 14 days of completing study sampling.
