| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Percentage Of Participants Who Achieved A Menstrual Blood Loss (MBL) Volume Of < 80 mL And A ≥ 50% Reduction From Baseline MBL Volume With Relugolix Plus E2/NETA | From Baseline up to last 35 days of treatment (up to Week 24) | A responder was a participant who had MBL volume of \< 80 mL and at least a 50% reduction from baseline MBL volume over the last 35 days of treatment (up to Week 24). All returned feminine products collected at each clinical visit were analyzed by the alkaline hematin method to obtain the MBL volume. MBL volume was measured over the Week 24/early termination feminine product collection interval (up to 35 days prior to the last dose of treatment). The percentage of participants who were responders are presented. As per the objective of the study, the pre-specified primary efficacy analyses compared relugolix plus E2/NETA with placebo. Therefore, only relugolix plus E2/NETA and placebo arms are presented. |
| Secondary | Percentage Of Participants With Amenorrhea Over The Last 35 Days Of Treatment | From Baseline up to last 35 days of treatment (up to Week 24) | Amenorrhea was defined as meeting 1 of the following criteria for 2 consecutive visits: 1. No feminine product returned due to reported amenorrhea; 2. No feminine product returned due to reports of spotting/negligible bleeding coupled with electronic diary (eDiary) data indicating infrequent non-cyclic bleeding/spotting; 3. Feminine product collection with a negligible observed MBL volume coupled with eDiary data indicating infrequent non-cyclic bleeding/spotting. As per the objective of the study, the pre-specified secondary efficacy analyses compared relugolix plus E2/NETA with placebo. Therefore, only relugolix plus E2/NETA and placebo arms are presented. |
| Secondary | Percent Change From Baseline At Week 24 In MBL Volume | Baseline, Week 24 | MBL volume was measured using the alkaline hematin method. As per the objective of the study, the pre-specified secondary efficacy analyses compared relugolix plus E2/NETA with placebo. Therefore, only relugolix plus E2/NETA and placebo arms are presented. |
| Secondary | Percentage Of Participants With A Hemoglobin Level ≤ 10.5 g/dL At Baseline Who Achieved An Increase Of > 2 g/dL From Baseline At Week 24 | From Baseline up to Week 24 | Blood samples were collected from participants for hemoglobin measurements. Percentages are based on number of participants with hemoglobin ≤ 10.5 gram (g)/deciliter (dL) at Baseline and reported at Week 24. As per the objective of the study, the pre-specified secondary efficacy analyses compared relugolix plus E2/NETA with placebo. Therefore, only relugolix plus E2/NETA with placebo arms are presented. |
| Secondary | Percentage Of Participants With A Maximum NRS Score ≤ 1 For Uterine Fibroid-Associated Pain Over The Last 35 Days Of Treatment | From Baseline up to Week 24 | Uterine fibroid-associated pain was assessed by a pain numerical rating scale (NRS). The pain NRS is a validated, single-item, self-reported measure, which asks respondents to rank their pain on an 11-point scale as follows: 0 (no pain), 1 to 3 (mild pain), 4 to 6 (moderate pain), and 7 to 10 (severe pain). Participants were asked to document, in an e-Diary, the worst pain associated with their uterine fibroids that they experienced during the last 24 hours, every day until the end of study drug administration. Pain evaluable participants, defined as those who had maximum NRS score ≥ 4 at Baseline and had at least 28 days (80% of the last 35 days of treatment) of pain scores recorded in the e-Diary, were analyzed. As per the objective of the study, the pre-specified secondary efficacy analyses compared relugolix plus E2/NETA with placebo. Therefore, only relugolix plus E2/NETA and placebo arms are presented. |
| Secondary | Percent Change From Baseline At Week 24 In Primary Uterine Fibroid Volume | Baseline, Week 24 | The volume of the primary uterine fibroid was measured by transvaginal or transabdominal ultrasound. As per the objective of the study, the pre-specified secondary efficacy analyses compared relugolix plus E2/NETA with placebo. Therefore, only relugolix plus E2/NETA and placebo arms are presented. |
| Secondary | Percent Change From Baseline At Week 24 In Uterine Volume | Baseline, Week 24 | The volume of the uterus was measured by transvaginal or transabdominal ultrasound. As per the objective of the study, the pre-specified secondary efficacy analyses compared relugolix plus E2/NETA with placebo. Therefore, only relugolix plus E2/NETA and placebo arms are presented. |
| Secondary | Change From Baseline At Week 24 In UFS-QoL Bleeding And Pelvic Discomfort Scale Score As Measured By The UFS-QoL (Q1, Q2, Q5) | Baseline, Week 24 | The Uterine Fibroid Symptom and Health-Related Quality of Life (UFS-QoL) Bleeding and Pelvic Discomfort (BPD) Scale has been derived from the UFS-QoL Symptoms Scale. The scale consists of the following 3 symptoms proximal to uterine fibroids: Heavy bleeding during your menstrual period (Question \[Q\] 1), passing blood clots during your menstrual period (Q2), and feeling tightness or pressure in your pelvic area (Q5). raw scores were transformed to a normalized score: Transformed Score = \[(Actual raw score - lowest possible raw score)/(Possible raw score range)\] \* 100 Transformed score ranges from 0 to 100 based on Likert scale (None of time, a little of time, some of the time, most of the time and all of the time). Lower score indicates minimal symptom severity and higher score indicates maximum symptom severity. As per the study objective, the pre-specified secondary efficacy analyses compared relugolix plus E2/NETA with placebo. Therefore, only these two arms are presented. |
| Secondary | Percent Change From Baseline At Week 12 In Bone Mineral Density At The Lumbar Spine (L1 To L4), As Assessed By DXA | Baseline, Week 12 | Bone mineral density (BMD) was assessed by dual-energy x-ray absorptiometry (DXA) at the lumbar spine (L1, L2, L3, and L4) at Baseline and at Week 12. The scans were read by the central radiology laboratory in accordance with the imaging charter. The same DXA machine was used at the local imaging center at each site and operated in the same scan mode for all images procured for an individual participant. All images were submitted for central reading. The central radiology laboratory collected and evaluated all DXA scans for acceptability and measured BMD. As per the objective of the study, the pre-specified secondary analyses compared relugolix plus E2/NETA with relugolix plus delayed E2/NETA at Week 12 and are presented below. |
| Secondary | Percent Change From Baseline At Week 24 In Bone Mineral Density At The Lumbar Spine (L1 To L4), Total Hip, And Femoral Neck | Baseline, Week 24 | BMD was assessed by DXA at the lumbar spine (L1, L2, L3, and L4), total hip, and femoral neck at Baseline and at Week 24. The scans were read by the central radiology laboratory in accordance with the imaging charter. The same DXA machine was used at the local imaging center at each site and operated in the same scan mode for all images procured for an individual participant. All images were submitted for central reading. The central radiology laboratory collected and evaluated all DXA scans for acceptability and measured BMD. As per the objective of the study, the pre-specified secondary efficacy analyses compared relugolix plus E2/NETA with placebo. Therefore, only relugolix plus E2/NETA and placebo arms are presented. |
