Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants With Endometrial Biopsy Results at Final Visit	The endometrial biopsy results was categorized as: normal results categorized as atrophic/inactive or proliferative, unsatisfactory with endometrial thickness =4 mm and missing biopsy with endometrial thickness =4 mm; abnormal results categorized as polyp, hyperplasia, and carcinoma; unknown result categorized as unsatisfactory with endometrial thickness >4 mm, missing biopsy with endometrial thickness >4 mm, unsatisfactory without transvaginal ultrasonography (TVU) result and missing biopsy without TVU result. The duration of estradiol exposure was combination of studies PR-04409.3 and PR-04509.	Final Visit (Day closest to Day 281)
Secondary	Change From Baseline in Participants Self-Assessment of the Symptoms of Vulvovaginal Atrophy (VVA) at Each Post-baseline Timepoints	Self-Assessment of the symptoms of VVA was evaluated for vaginal dryness, vaginal Itching, dysuria, and dyspareunia by a questionnaire. Questionnaire consisted of 5 questions scaled from 0 to 3 level of intensity, where 0-none indicated symptom not present; 1-mild indicated symptom is present but may be intermittent; does not interfere with your activities or lifestyle; 2-moderate indicated symptom is present, aware of the symptom but activities and lifestyle are only occasionally affected; 3-severe indicated usually aware and bothered by the symptom and have modified your activities and/or lifestyle due to the symptom. Higher score indicated most bothersome symptoms. A negative change from Baseline indicates improvement. Participants at Final visit/Visit 7 included those who were to complete all the evaluations in the study including who prematurely withdrew from the study.	Baseline (Baseline/Visit 1 for this study was the same as Final Visit/Visit 5 for completers of PR-04409.3) to Weeks 4, 8, 16, 24, 32, 40 and Final Visit (Day closest to Day 281)
Secondary	Change From Baseline in Vaginal Cytology: Percentage of Superficial Vaginal Cells	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. Participants at Final visit/Visit 7 included those who were to complete all the evaluations in the study including who prematurely withdrew from the study.	Baseline (Baseline/Visit 1 for this study was the same as Final Visit/Visit 5 for completers of PR-04409.3) to Week 40 and Final Visit (Day closest to Day 281)
Secondary	Change From Baseline in Vaginal Cytology: Percentage of Parabasal Vaginal Cells	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. Participants at Final visit/Visit 7 included those who were to complete all the evaluations in the study including who prematurely withdrew from the study.	Baseline (Baseline/Visit 1 for this study was the same as Final Visit/Visit 5 for completers of PR-04409.3) to Week 40 and Final Visit (Day closest to Day 281)
Secondary	Change From Baseline in Vaginal pH	Vaginal pH was obtained at 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. Participants at Final visit/Visit 7 included those who were to complete all the evaluations in the study including who prematurely withdrew from the study.	Baseline (Baseline/Visit 1 for this study was the same as Final Visit/Visit 5 for completers of PR-04409.3) to Week 40 and Final Visit (Day closest to Day 281)
Secondary	Change From Baseline as Per Investigator's Assessment of Each of the Signs of VVA	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 scored on a 4-point scale where: 0=none, 1=mild, 2=moderate, or 3= severe. The negative change from Baseline indicates improvement. Participants at Final visit/Visit 7 included those who were to complete all the evaluations in the study including who prematurely withdrew from the study.	Baseline (Baseline/Visit 1 for this study was the same as Final Visit/Visit 5 for completers of PR-04409.3) to Week 40 and Final Visit (Day closest to Day 281)
Secondary	Number of Participants With At Least One Treatment Emergent Adverse Event (TEAE)	An adverse event is any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with use of a medicinal (investigational) product, whether or not related to medicinal (investigational) product. TEAE are defined as those AEs with onset date on or after the first dose date of study drug in Study PR-04509, or adverse events that worsen after the first dose date of study drug in Study PR-04509.	Up to Week 40
