During two consecutive 28-day treatment periods (treatment periods 1 and 2), separated by a washout period of 28 days, the participants will receive each of the following treatments according to their assigned treatment sequence
Drug: Dapivirine Vaginal Ring-004 and no tampons
Dapivirine Vaginal Ring-004 for 28 days, with menses, no tampon use (Treatment A),

Drug: Dapivirine Vaginal Ring-004 with no menses
Dapivirine Vaginal Ring-004 for 28 days, with no menses occurring (Treatment E; treatment period 3).

Active Comparator: Cohort II
In Cohort II, eligible participants will be randomly assigned to one of two treatment sequences (CDE or DCE). During two consecutive 28-day treatment periods (treatment periods 1 and 2), separated by a washout period of 28 days, the participants will receive each of the following treatments according to their assigned treatment sequence
Drug: Dapivirine Vaginal Ring-004 with no menses

Other Name: Treatment E

Drug: Dapivirine Vaginal Ring-004 and same ring inserted after menses
Dapivirine Vaginal Ring-004 used continuously until the start of menses, at which time the ring will be removed, and the same ring re-inserted five days later (estimated completion of menses) (Treatment C)
Other Name: Treatment C

Drug: Dapivirine Vaginal Ring-004 and new ring inserted after menses
Dapivirine Vaginal Ring-004 used continuously until the start of menses, at which time the ring will be removed, and a new ring inserted five days later (estimated completion of menses) (Treatment D)
Other Name: Treatment D




Primary Outcome Measures :
  1. 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

  2. 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 Outcome Measures :
  1. 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. [ Time Frame: 28 days ]
    To assess the impact on the local and systemic PK of dapivirine, delivered by the Dapivirine Vaginal Ring-004 when the ring is removed at the start of menses, and re-inserted after completion of menses.

  2. 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 [ Time Frame: 28 days ]
    To assess the impact on the local and systemic PK of dapivirine, delivered by the Dapivirine Vaginal Ring-004 when the ring is removed at the start of menses, and a new ring inserted after completion of menses.

  3. The residual amounts of dapivirine in used vaginal rings, removed at the onset of menses, where applicable, or on Day 28. [ Time Frame: 28 days ]
    To assess residual levels of dapivirine in used rings.

  4. 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. [ Time Frame: 28 days ]
    To assess the safety of the Dapivirine Vaginal Ring-004 in healthy, HIV-negative women.
