This study will evaluate the hypothesis that intravaginal rings (IVRs) can safely and in a
sustained fashion, deliver the antiretroviral (ARV) drugs - tenofovir disoproxil fumarate
(TDF), emtricitabine (FTC), and maraviroc (MVC), in healthy women when used in the following
drug combinations: 1) TDF ("Single" IVR); 2) TDF-FTC ("Dual" IVR) and; 3) TDF-FTC-MVC
("Triple" IVR).
TDF = tenofovir disoproxil fumarate; FTC = emtrcitabine; MVC = maraviroc

Primary | Number of Participants With Specific Graded Adverse Events in Single, Dual, and Triple Antiretroviral (ARV) Intravaginal Rings (IVRs) | Number of Adverse Events (AEs) was recorded. Safety parameters were monitored for each IVR combination and the grading scale for each parameter followed the Female Genital Grading Table for Use in Microbicide Studies. AEs not included in that table were graded using the Division of AIDS (DAIDS) Table for Grading the Severity of Adult and Pediatric Adverse Events (DAIDS AE Grading Table), Version 2.0, November 2014 (Grade 1 = mild, Grade 2 = Moderate, Grade 3 = Severe, Grade 4 = Potentially Life-Threatening). | Days 0-21 following insertion of each IVR. | |
Primary | Pharmacokinetics of the Single, Dual and Triple ARV IVRs: Cervicovaginal Fluid (CVF) | Drug concentrations [tenofovir (TFV), tenofovir disoproxil fumarate (TDF), emtricitabine (FTC) and maraviroc (MVC)] in cervicovaginal fluids (CVF) for each IVR combination. | Time points at which outcome measure was assessed are Days 2 (after IVR insertion) and 7 (day of IVR removal). | |
Primary | Pharmacokinetics of the Single, Dual and Triple ARV IVRs: Cervicovaginal Lavage (CVL) | Drug concentrations [tenofovir disoproxil fumarate (TDF), emtricitabine (FTC) and maraviroc (MVC)] in cervicovaginal lavage (CVL) were evaluated for each IVR combination. | Time points at which outcome measure was assessed are Days 2 (after IVR insertion) and 7 (day of IVR removal). | |
Primary | Pharmacokinetics of the Single, Dual and Triple ARV IVRs: Vaginal Tissue | Drug concentrations [tenofovir disoproxil fumarate (TDF), tenofovir (TFV), tenofovir diphosphate (TFV-DP), emtricitabine (FTC) and maraviroc (MVC)] in vaginal tissue (VT) were evaluated for each IVR combination. | Time points at which outcome measure was assessed are Days 2 (after IVR insertion) and 7 (day of IVR removal). | |
Primary | Pharmacokinetics of the Single, Dual and Triple ARV IVRs: Plasma | Drug concentrations [tenofovir disoproxil fumarate (TDF), emtricitabine (FTC) and maraviroc (MVC)] in plasma were evaluated for each IVR combination. | Time points at which outcome measure was assessed are Days 2 (after IVR insertion) and 7 (day of IVR removal). | |
Primary | Pharmacokinetics of the Single, Dual and Triple ARV IVRs: Terminal Half-life | Drug concentrations [tenofovir disoproxil fumarate (TDF), emtricitabine (FTC) and maraviroc (MVC)] in terminal half-life were evaluated for each IVR combination. | Time points at which outcome measure was assessed are Day 7 (day of IVR removal) and daily up to 14 days. | |
Secondary | Acceptability of the IVRs | Acceptability of the IVRs was assessed through reported willingness to use the IVR for 28 days in a real-world setting on a likert scale, 1 being "not at all confident" to 5 being "completely confident" for Periods 1 and 2. | Days 0-21 following insertion of each IVR. |
