Brief summary

The primary objective of this study is to compare the efficacy of WC3011 with placebo vaginal gel in postmenopausal women for the relief of vaginal dryness caused by vaginal atrophy as measured by self-assessment, vaginal pH and vaginal smear.

MeasureTime frameDescription
Change From Baseline in Participant's Self-Assessment of Severity of Vaginal Dryness to Final AssessmentBaseline (Day 0) to final assessment (Up to Week 12)Participant's self-assessment of Vaginal Dryness was scored on a 4-point scale where: 0=none, 1=mild, 2=moderate or 3=severe. Higher scores indicate the most bothersome symptoms. A negative change from Baseline indicates improvement. Final assessment is defined as the last available postbaseline assessment.
Change From Baseline in Vaginal pH to Final AssessmentBaseline (Day 0) to final assessment (Up to Week 12)Vaginal pH was obtained at baseline and final visit of the study. The pH was a numeric value from 0 to 14 expressing the acidity or alkalinity of the vaginal fluids where 7 was neutral, lower values were more acidic (values of 0-6) and higher values more alkaline (values of 8-14). A negative change from Baseline indicates improvement. Final assessment is defined as the last available postbaseline assessment.
Change From Baseline in the Percentage of Vaginal Superficial Cells to Final AssessmentBaseline (Day 0) to final assessment (Up to Week 12)Vaginal wall smears were collected from each participant. The smears were sent to the central laboratory for analysis to determine the percentage of superficial cells. A positive change from Baseline indicates improvement. Final assessment is defined as the last available postbaseline assessment.
Change From Baseline in the Percentage of Vaginal Parabasal Cells to Final AssessmentBaseline (Day 0) to final assessment (Up to Week 12)Vaginal wall smears were collected from each participant. The smears were sent to the central laboratory for analysis to determine the percentage of parabasal cells. A negative change from Baseline indicates improvement. Final assessment is defined as the last available postbaseline assessment.

Each symptom was scored on a 4-point scale where: 0=none, 1=mild, 2=moderate, or 3=severe. Higher scores indicate the most bothersome symptoms. A negative change from Baseline indicates improvement. Final Assessment is defined as the last available post-baseline assessment for the given efficacy endpoint.
Percentage of Participants With Vaginal Bleeding Associated With Sexual ActivityBaseline (Day 0) and Weeks 2, 4, 8, 12 and Final AssessmentVaginal bleeding associated with sexual activity was assessed by participants as either present or absent.

Time frame: Baseline (Day 0) to final assessment (Up to Week 12)

Population: Modified Intent-to-Treat (mITT) Population included participants in safety population who had at least 1 postbaseline primary efficacy assessment and had: ≤5% superficial cells on a vaginal wall smear, a vaginal pH \>5.0 and participant's most bothersome symptom of VVA was vaginal dryness with moderate to severe intensity. Number analyzed is the number of participants with available data at the given timepoint.

Change From Baseline in the Percentage of Vaginal Parabasal Cells to Week 12

Vaginal wall smears were collected from each participant. The smears were sent to the central laboratory for analysis to determine the percentage of parabasal cells. A negative change from Baseline indicates improvement.

Time frame: Baseline (Day 0) to Week 12

Population: mITT Population included participants in safety population who had at least 1 postbaseline primary efficacy assessment and had: ≤5% superficial cells on a vaginal wall smear, a vaginal pH \>5.0 and participant's most bothersome symptom of VVA was vaginal dryness with moderate to severe intensity. Number analyzed is the number of participants with available data at the given timepoint.

Percentage of Participants With Vaginal Bleeding Associated With Sexual Activity

Vaginal bleeding associated with sexual activity was assessed by participants as either present or absent. Number of participants with assessment present are reported. Final assessment is defined as the last available postbaseline assessment.

Time frame: Baseline (Day 0) and Weeks 2, 4, 8, 12 and Final Assessment

Population: mITT Population included participants in safety population who had at least 1 postbaseline primary efficacy assessment and had: ≤5% superficial cells on a vaginal wall smear, a vaginal pH \>5.0 and participant's most bothersome symptom of VVA was vaginal dryness with moderate to severe intensity. Number analyzed is the number of participants with available data at the given timepoint.
