The Percentage of Women With the Composite Endpoint of Abnormal Safety Findings.
Časové okno: 12 weeks
|
A composite endpoint was defined as the percentage of participants with any post-baseline abnormal finding from pelvic/speculum examination, colposcopy finding, STI diagnoses, laboratory test of DAIDS grade 3 or higher and any product-related AE. DAIDS severity grades are defined as follows: Grade 1 = mild Grade 2 = moderate Grade 3 = severe Grade 4 = potentially life-threatening Grade 5 = death |

Changes in the Vaginal Flora
Časové okno: 16 weeks
|
Cervicovaginal fluid specimens will be obtained to determine vaginal flora before first gel application and at Visits 3, 5, and 6. Appropriate statistical analyses incorporating repeated measures will be used to assess the changes in the vaginal flora in women using Dapivirine Gel 4759, 0.05% 2.5g, Dapivirine Gel 4789, 0.05% 2.5g or the vaginal HEC-based universal placebo gel, 2.5g. Nugent scores were used to assess changes in vaginal flora, and were categorized into three levels: (1) negative for BV (score: 0-3); (2) altered vaginal flora (score: 4-6); and (3) BV (score: 7-10). |

The Adherence to Once Daily Application of a Vaginal Microbicide Gel Over a 12-week Period in Healthy, Sexually Active, HIV-negative Women
Časové okno: 12 weeks
|
Adherence is defined as the percentage of participants who used the gel each day of the preceding 14 days, based on participant self reports.

Changes in the Vaginal pH
Časové okno: 12 weeks
|
Cervicovaginal fluid specimens will be obtained to determine vaginal pH before first gel application and at screening, enrolment and visit 5 (week 12).
Appropriate statistical analyses incorporating repeated measures will be used to assess the changes in the vaginal pH in women using Dapivirine Gel 4759, 0.05% 2.5g, Dapivirine Gel 4789, 0.05% 2.5g or the vaginal HEC-based universal placebo gel, 2.5g.

The Distribution of Dapivirine Levels Observed in Vaginal Fluid at Each Specified Time Point.
Časové okno: 12 weeks. Measured at 2, 4, and 8 weeks post-enrolment and at one of these at week 12; 24, 48, or 72 hours after gel discontinuation. (Participants were randomized to have vaginal fluid samples collected at one of these visits (5a, 5b, or 5c).
|
The distribution of dapivirine levels observed in each type of sample will be summarized using simple descriptive statistics.
In addition, the proportion of women with detectable dapivirine concentrations will be calculated for each type of sample at each collection time point.
Exploratory analyses of dapivirine concentration data will also be performed to take into account information reported in a diary regarding menses and tampon use throughout the trial.
|
12 weeks. Measured at 2, 4, and 8 weeks post-enrolment and at one of these at week 12; 24, 48, or 72 hours after gel discontinuation. (Participants were randomized to have vaginal fluid samples collected at one of these visits (5a, 5b, or 5c).

The Distribution of Dapivirine Levels Observed in Vaginal Tissue at Each Specified Time Point.
Časové okno: 12 weeks. Measured at 2, 4, and 8 weeks post-enrolment and at one of these at week 12; 24, 48, or 72 hours after gel discontinuation. (Participants were randomized to have vaginal fluid samples collected at one of these visits (5a, 5b, or 5c).

Acceptability of Once Daily Application of a Vaginal Microbicide Gel Over a 12-week Period in Healthy, Sexually Active, HIV-negative Women
Časové okno: 12 weeks
|
Acceptability was assessed as the percentage of participants at week 12 who were willing to use the gel every day if proven to prevent HIV.
