Trial Outcomes & Findings for Multicenter Study to Evaluate Safety and Efficacy of WC3011 (Estradiol Vaginal Cream) in Postmenopausal Women (NCT NCT01816139)

NCT ID: NCT01816139

Last Updated: 2022-05-09

Results Overview

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.

PRIMARY outcome

Timeframe: 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.

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.

Number analyzed is the number of participants with available data at the given timepoint.

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.

Number analyzed is the number of participants with available data at the given timepoint.

Self-Assessment of the symptoms of VVA (vaginal and/or vulvar irritation/ Itching, dysuria, and dyspareunia) were evaluated by a questionnaire. 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.

Number analyzed is the number of participants with available data at the given timepoint.

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.

Number analyzed is the number of participants with available data at the given timepoint.

Investigator's assessment of vaginal health was performed by visual inspection of the vagina with respect to the signs of VVA: atrophy, pallor, vaginal dryness, friability, and petechiae each graded on a 4-point scale where: 0=none, 1=mild, 2=moderate or 3=severe. Higher scores are worse. A negative change from Baseline indicates improvement. Final assessment is defined as the last available postbaseline assessment.
