Outcome Measures

Primary Outcome Measures

  1. Percentage of Participants With Hyperplasia at Screening [Screening]

    Endometrial hyperplasia was assessed by endometrial biopsies. All endometrial biopsies were read centrally by 2 primary pathologists. Participants were considered to have a diagnosis of hyperplasia if both pathologists read hyperplasia (simple hyperplasia with or without atypia or complex hyperplasia with or without atypia). If the both pathologists disagreed on the presence of hyperplasia, a third pathologist was consulted, with the final diagnosis determined by the majority opinion.

  2. Percentage of Participants With Hyperplasia at Month 12 [Month 12]

    Endometrial hyperplasia was assessed by endometrial biopsies. All endometrial biopsies were read centrally by 2 primary pathologists. Participants were considered to have a diagnosis of hyperplasia if both pathologists read hyperplasia (simple hyperplasia with or without atypia or complex hyperplasia with or without atypia). If the both pathologists disagreed on the presence of hyperplasia, a third pathologist was consulted, with the final diagnosis determined by the majority opinion.

  3. Bone Mineral Density (BMD) of Lumbar Spine at Screening [Screening]

    BMD measurements of the anteroposterior lumbar spine were acquired by dual-energy x-ray absorptiometry (DXA), twice during screening in participants who entered the osteoporosis substudy. The second scan was to be performed on the same day as the first; however, the participant was to be removed completely from the table after the first scan and repositioned for the second scan. An average of the 2 readings was reported.

  4. Percent Change From Baseline in Bone Mineral Density (BMD) of Lumbar Spine at Month 12 [Baseline, Month 12]

    BMD measurements of the anteroposterior lumbar spine were acquired by DXA, twice at Month 12 in participants who entered the osteoporosis substudy. The second scan was to be performed on the same day as the first; however, the participant was to be removed completely from the table after the first scan and repositioned for the second scan. An average of the 2 readings was reported.

  5. Bone Mineral Density (BMD) of Total Hip at Screening [Screening]

    BMD measurements of the total hip were acquired by DXA, twice during screening in participants who entered the osteoporosis substudy. The second scan was to be performed on the same day as the first; however, the participant was to be removed completely from the table after the first scan and repositioned for the second scan. An average of the 2 readings was reported.

  6. Percent Change From Baseline in Bone Mineral Density (BMD) of Total Hip at Month 12 [Baseline, Month 12]

    BMD measurements of the total hip were acquired by DXA, twice at Month 12 in participants who entered the osteoporosis substudy. The second scan was to be performed on the same day as the first; however, the participant was to be removed completely from the table after the first scan and repositioned for the second scan. An average of the 2 readings was reported.

Secondary Outcome Measures

  1. Percentage of Days With Breast Pain [Screening, Week 1 to 4, 5 to 8, 9 to 12, 13 to 16, 17 to 20, 21 to 24, 25 to 28, 29 to 32, 33 to 36, 37 to 40, 41 to 44, 45 to 48, 49 to 52]

    Percentage of days with breast pain in each 4-week period (for example, Week 1 to 4, 5 to 8) calculated as the number of days on which a participants reported breast pain divided by total number of days with data recorded multiplied by 100. Data was collected every day after randomization up to Year 1 and was analyzed in 4 weeks intervals. Data for screening was not analyzed since data were collected only for 7 days at screening which was not considered comparable to 4-week post-baseline data.

  2. Percentage of Participants With Uterine Bleeding or Spotting [Screening, Week 1 to 4, 5 to 8, 9 to 12, 13 to 16, 17 to 20, 21 to 24, 25 to 28, 29 to 32, 33 to 36, 37 to 40, 41 to 44, 45 to 48, 49 to 52]

    Data was collected every day after randomization up to Year 1 and was analyzed in 4 weeks intervals. Data for screening was not analyzed since data were collected only for 7 days at screening which was not considered comparable to 4-week post-baseline data.

  3. Percentage of Participants With Hyperplasia at Month 24 [Month 24]

    Endometrial hyperplasia was assessed by endometrial biopsies. All endometrial biopsies were read centrally by 2 primary pathologists. Participants were considered to have a diagnosis of hyperplasia if both pathologists read hyperplasia (simple hyperplasia with or without atypia or complex hyperplasia with or without atypia). If the both pathologists disagreed on the presence of hyperplasia, a third pathologist was consulted, with the final diagnosis determined by the majority opinion.

  4. Percent Change From Baseline in Bone Mineral Density (BMD) of Lumbar Spine at Month 24 [Baseline, Month 24]

    BMD measurements of the anteroposterior lumbar spine were acquired by DXA, twice at Month 24 in participants who entered the osteoporosis substudy. The second scan was to be performed on the same day as the first; however, the participant was to be removed completely from the table after the first scan and repositioned for the second scan. An average of the 2 readings was reported.

  5. Percent Change From Baseline in Bone Mineral Density (BMD) of Total Hip at Month 24 [Baseline, Month 24]

    BMD measurements of the total hip were acquired by DXA, twice at Month 24 in participants who entered the osteoporosis substudy. The second scan was to be performed on the same day as the first; however, the participant was to be removed completely from the table after the first scan and repositioned for the second scan. An average of the 2 readings was reported.

7. Secondary Outcome
Title Percentage of Days With Breast Pain
Description Percentage of days with breast pain in each 4-week period (for example, Week 1 to 4, 5 to 8) calculated as the number of days on which a participants reported breast pain divided by total number of days with data recorded multiplied by 100. Data was collected every day after randomization up to Year 1 and was analyzed in 4 weeks intervals. Data for screening was not analyzed since data were collected only for 7 days at screening which was not considered comparable to 4-week post-baseline data.
Time Frame Screening, Week 1 to 4, 5 to 8, 9 to 12, 13 to 16, 17 to 20, 21 to 24, 25 to 28, 29 to 32, 33 to 36, 37 to 40, 41 to 44, 45 to 48, 49 to 52

9. Secondary Outcome
Title Percentage of Participants With Hyperplasia at Month 24
Description Endometrial hyperplasia was assessed by endometrial biopsies. All endometrial biopsies were read centrally by 2 primary pathologists. Participants were considered to have a diagnosis of hyperplasia if both pathologists read hyperplasia (simple hyperplasia with or without atypia or complex hyperplasia with or without atypia). If the both pathologists disagreed on the presence of hyperplasia, a third pathologist was consulted, with the final diagnosis determined by the majority opinion.
Time Frame Month 24

Outcome Measure Data

Analysis Population Description
EE analysis population for Year 2 included all randomized participants who took at least 1 dose of test article, participated in study extension, had a screening endometrial biopsy with readings by at least 2 blinded central pathologists, had biopsy during Month 24, or had hyperplasia diagnosed before Month 24 and had no major protocol violations.

11. Secondary Outcome
Title Percent Change From Baseline in Bone Mineral Density (BMD) of Total Hip at Month 24
Description BMD measurements of the total hip were acquired by DXA, twice at Month 24 in participants who entered the osteoporosis substudy. The second scan was to be performed on the same day as the first; however, the participant was to be removed completely from the table after the first scan and repositioned for the second scan. An average of the 2 readings was reported.
Time Frame Baseline, Month 24

Outcome Measure Data

Analysis Population Description
MITT population for BMD of total hip: all participants who took at least 1 dose of test article, participated in study extension, and had a baseline and at least 1 on-therapy evaluation of BMD (scans acquired more than 60 days after the test article administration was stopped were excluded) at Year 2. Missing values imputed using LOCF method.
