- •Untreated symptomatic urogenital infections, e.g. urinary tract or other STIs, or other gynaecological conditions such as vaginal itching, pain, or discharge, within two weeks prior to enrollment;
- •Have a Grade 2 or higher pelvic examination finding, according to the Division of AIDS (DAIDS) Table for Grading the Severity of Adult and Pediatric Adverse Events; Addendum 1 Female Genital Grading Table for Use in Microbicide Studies;
- •History of significant urogenital or uterine prolapse, undiagnosed vaginal bleeding, urethral obstruction, incontinence or urge incontinence;
- •Current vulvar or vaginal symptoms/abnormalities that could influence the trial results;

Outcomes
Primary Outcomes
Dapivirine concentrations in vaginal fluid and in plasma, measured at specified time points before, during, and after menses, when no tampons are used, during a 28-day ring use period.
Time Frame: 28 days
To determine the effect of menses on the local and systemic pharmacokinetics (PK) of dapivirine, delivered by the Dapivirine Vaginal Ring-004, in healthy, HIV-negative women
Dapivirine concentrations in vaginal fluid and in plasma, measured at specified time points before, during, and after menses, when tampons are used, during a 28-day ring use period.
Time Frame: 28 days
To determine the effect of tampon use during menses on the local and systemic PK of dapivirine, delivered by the Dapivirine Vaginal Ring-004, in healthy, HIV-negative women.
Secondary Outcomes
- Dapivirine concentrations in vaginal fluid and in plasma, measured at specified time points before, during, and after menses when the ring is removed at the onset of menses, and re-inserted after completion of menses for the remainder of a 28-day period.(28 days)
- Safety will be assessed through the reporting of AEs, including SAEs, laboratory safety assessments (haematology, biochemistry, and urinalysis), physical and gynaecological examinations, and vaginal flora and pH assessments during the trial.(28 days)
- Dapivirine concentrations in vaginal fluid and in plasma, measured at specified time points before, during, and after menses when the ring is removed at the onset of menses, and a new ring inserted after completion of menses(28 days)
- The residual amounts of dapivirine in used vaginal rings, removed at the onset of menses, where applicable, or on Day 28.(28 days)
