Brief Summary
The purpose of this study is to determine the benefit of relugolix 40 milligrams (mg) once a day co-administered with estradiol (E2) 1 mg and norethindrone acetate (NETA) 0.5 mg compared with placebo for 24 weeks on heavy menstrual bleeding associated with uterine fibroids.

Outcome Measures
Primary Outcomes (1)
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
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.
From Baseline up to last 35 days of treatment (up to Week 24)

Study Arms (3)
Relugolix plus E2/NETA (Group A)
EXPERIMENTALRelugolix co-administered with E2/NETA for 24 weeks.
Relugolix plus Delayed E2/NETA (Group B)
EXPERIMENTALRelugolix co-administered with E2/NETA placebo for 12 weeks, followed by relugolix co-administered with E2/NETA for 12 weeks.
Placebo (Group C)
PLACEBO COMPARATORRelugolix placebo co-administered with E2/NETA placebo for 24 weeks.
Interventions
Relugolix (40 mg) tablet administered orally once daily.
E2 (1.0 mg)/NETA (0.5 mg) co-formulated capsule administered orally once daily.
E2 (0 mg)/NETA (0 mg) placebo capsule administered orally once daily and designed to match the capsule containing E2/NETA in size, shape, color, and odor.
Relugolix (0 mg) placebo tablet administered orally once daily and manufactured to match the relugolix tablet in size, shape, color, and odor.
Eligibility Criteria
You may qualify if:
- Premenopausal female aged 18 to 50 years old (inclusive) on the day of signing and dating the informed consent form.
- Has regularly occurring menstrual periods of ≤ 14 days duration with a cycle of 21 to 38 days from the start of 1 menstrual period until the start of the next, by participant history for at least 3 months prior to the first screening visit.
- Has a diagnosis of uterine fibroids that is confirmed by a transvaginal and/or transabdominal ultrasound performed during the screening period.
- Has heavy menstrual bleeding associated with uterine fibroids as evidenced by an MBL of ≥ 160 milliliter (mL) during 1 cycle or ≥ 80 mL per cycle for 2 menstrual cycles as measured by the alkaline hematin method during the screening period.
You may not qualify if:
- Has transvaginal and/or transabdominal ultrasound during the screening period demonstrating pathology other than uterine fibroids that could be responsible for or contributing to the patient's heavy menstrual bleeding.
- Has known rapidly enlarging uterine fibroids in the opinion of the investigator.
- Has a weight that exceeds the weight limit of the DXA scanner or has a condition that precludes an adequate DXA measurement at the lumbar spine and proximal femur.
- Has a history of or currently has osteoporosis, or other metabolic bone disease, hyperparathyroidism, hyperprolactinemia, hyperthyroidism, anorexia nervosa, or low traumatic (from the standing position) or atraumatic fracture (toe, finger, skull, face and ankle fractures are allowed). A history of successfully treated hyperparathyroidism, hyperprolactinemia, or hyperthyroidism is allowed if the participant's bone mineral density is within normal limits.
- Has a history of the use of bisphosphonates, calcitonin, calcitriol, ipriflavone, teriparatide, denosumab, or any medication other than calcium and vitamin D preparations to treat bone mineral density loss.
- Has been a participant in an investigational drug or device study within the 1 month prior to the first screening visit.
