Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change From Baseline in Participant's Self-Assessment of Symptom of Vulvovaginal Atrophy (VVA): Dyspareunia (Pain Associated With Sexual Activity) to Final Assessment	Participant's self-assessment of the symptom of VVA (dyspareunia) was scored on a 4-point scale where: 0=none, 1=mild, 2=moderate or 3=severe. Higher score indicates 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.	Baseline (Day 0) to final assessment (Up to Week 12)
Primary	Change From Baseline in Vaginal pH to Final Assessment	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 post-baseline assessment for the given efficacy endpoint.	Baseline (Day 0) to final assessment (Up to Week 12)
Primary	Change From Baseline in the Percentage of Vaginal Superficial Cells to Final Assessment	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.	Baseline (Day 0) to final assessment (Up to Week 12)
Primary	Change From Baseline in the Percentage of Vaginal Parabasal Cells to Final Assessment	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.	Baseline (Day 0) to final assessment (Up to Week 12)
Secondary	Change From Baseline in Participant's Self-Assessment of the Symptom of VVA: Dyspareunia to Weeks 2, 4, 8, and 12	Participant's self-assessment of the symptom of VVA (dyspareunia) was scored on a 4-point scale where: 0=none, 1=mild, 2=moderate or 3=severe. Higher score indicates the most bothersome symptoms. A negative change from Baseline indicates improvement.	Baseline to Weeks 2, 4, 8 and 12
Secondary	Change From Baseline in Participant's Self-Assessment of the Other Symptoms of VVA to Weeks 2, 4, 8, 12, and Final Assessment	Self-Assessment of the symptoms of VVA, other than dyspareunia and vaginal bleeding associated with sexual activity, (vaginal and/or vulvar irritation/itching, dysuria and vaginal dryness) 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.	Baseline (Day 0) to Weeks 2, 4, 8, 12, and final assessment (Up to Week 12)
Secondary	Percentage of Participants With Vaginal Bleeding Associated With Sexual Activity at Each Visit	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 post-baseline assessment for the given efficacy endpoint.	Baseline (Day 0), Weeks 2, 4, 8, 12 and final assessment (Up to Week 12)
Secondary	Change From Baseline in the Investigator's Assessment of Each of the Signs of VVA to Week 12 and Final Assessment	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.	Baseline (Day 0) to Week 12 and Final assessment (Up to Week 12)
Secondary	Change From Baseline in Vaginal pH 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.	Baseline to Week 12
Secondary	Change From Baseline in the Percentage of Vaginal Superficial 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 superficial cells. A positive change from Baseline indicates improvement.	Baseline to Week 12
Secondary	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.	Baseline to Week 12
