Study Arms:
- TFV/LNG IVR (8-10mg/20μg) (Continuous) (Type: EXPERIMENTAL): TFV/LNG IVR is an intravaginal ring 55.0 mm in diameter, consisting of two segments of polyurethane tubing with an outer cross-sectional diameter of 5.5 mm: a longer segment (135 mm) containing white to off-white TFV paste and a shorter one (34 mm) with a translucent LNG core. Used for 90 days (continuous).
- TFV/LNG IVR (8-10mg/20μg) (Interrupted) (Type: EXPERIMENTAL): TFV/LNG IVR is an intravaginal ring 55.0 mm in diameter, consisting of two segments of polyurethane tubing with an outer cross-sectional diameter of 5.5 mm: a longer segment (135 mm) containing white to off-white TFV paste and a shorter one (34 mm) with a translucent LNG core. Used for 90 days (3x28 days interrupted).
- Placebo (Continuous) (Type: PLACEBO_COMPARATOR): Intravaginal ring 55.0 mm in diameter, consisting of two segments of polyurethane tubing with an outer diameter of 5.5 mm containing no active experimental ingredients. Used for one month. Used for 90 days (continuous).
- Placebo (Interrupted) (Type: PLACEBO_COMPARATOR): Intravaginal ring 55.0 mm in diameter, consisting of two segments of polyurethane tubing with an outer diameter of 5.5 mm containing no active experimental ingredients. Used for one month. Used for 90 days (3x28 days interrupted).
