This Phase 2a clinical trial will evaluate the safety, pharmacokinetics and pharmacodynamics of, and the tolerability and adherence to two novel intravaginal rings (IVRs). The tenofovir/levonorgestrel (TFV/LNG) IVR and TFV IVRs are designed to provide HIV (and HSV-2) prevention with and without contraceptive for pregnancy prevention, respectively. Women will be protected from pregnancy by abstinence from vaginal intercourse or agreeing to consistently use condoms; concurrent use of a non-hormonal copper intrauterine device is permitted. The study will enroll healthy, HIV-negative, non-pregnant, menstruating women aged 18-34 years, inclusive, and not currently infected with hepatitis B virus, who are assessed to be at lower risk for HIV. The goal is to enroll fifty (50) women in Western Kenya. The participants will be randomized 2:2:1 to use one of the following continuous delivery IVRs: twenty (20) women to use the TFV/LNG IVR; ten (10) women to use the TFV IVR; and ten (10) women to use the placebo IVR. Participants will attend up to ten (10) routine study visits that may include physical and pelvic exams, collection of venous blood, vaginal fluid and cervical mucus, and behavioral questionnaires. A subset of twenty (20) women will participate in in-depth interviews.
