Brief Summary:
The purpose of the study is to evaluate the safety, acceptability, and PK/PD profile of maraviroc gel following rectal and vaginal administration. The study also includes oral exposure to maraviroc.

Condition or disease Intervention/treatment Phase
HIV/AIDS Drug: Maraviroc 300 mg tablet (PO) and Maraviroc 1% gel (PR and PV) Phase 1

Detailed Description:

Trail 11991 is a Phase 1 randomized, open label, single-site trial. Approximately 19 participants (9 female, 10 male) will be randomized to the 9 female study arms and 4 male study arms with 1-3 participants per arm. The randomization will be completed for the product sequence and the timing of tissue sample collection.

All participants will receive both study products by multiple routes of administration (i.e., PO, PR, [and PV for female participants]), and they will be randomized to the order of product sequence and specimen sampling schedule. The male participants will receive oral and rectal MVC and the female participants will receive oral, rectal, and vaginal MVC, in randomized sequence.

Participant accrual will take approximately 6 months. Male participants will be on study for approximately 9 to 12 weeks. Female participants will be on study for approximately 12 to 16 weeks. The total duration of the study will be approximately 9 months.
