Brief Summary:
The purpose of this study is to determine the benefit and safety of relugolix 40 mg once daily co-administered with low dose estradiol and norethindrone acetate compared with placebo for 24 weeks on heavy menstrual bleeding associated with uterine fibroids. Additionally, this study is designed to evaluate the benefit of relugolix 40 mg once daily for 12 weeks followed by 12 weeks of relugolix 40 mg once daily co-administered with low dose estradiol and norethindrone acetate compared with placebo for 24 weeks in the same population.

Condition or disease Intervention/treatment Phase
Heavy Menstrual Bleeding Uterine Fibroid Drug: Relugolix Drug: Estradiol/norethindrone acetate Drug: Placebo for E2/NETA Drug: Placebo for relugolix Phase 3

Detailed Description:

This study is an international phase 3 randomized, double-blind, placebo-controlled efficacy and safety study to evaluate 24 weeks of oral daily relugolix 40 mg co-administered with low-dose estradiol and norethindrone acetate (Group A) and 12 weeks of daily oral relugolix 40 mg alone followed by 12 weeks of daily oral relugolix 40 mg co-administered with low-dose estradiol and norethindrone acetate (Group B) compared with 24 weeks of placebo (Group C).

Approximately 390 women with heavy menstrual bleeding associated with uterine fibroids will be enrolled in the study and will participate for approximately 10 months. Participation will include an ~ 11 week screening period, 24 weeks of treatment and a follow up period of ~ 30 days. A diagnosis of uterine fibroids will be confirmed during the screening period by centrally-reviewed transvaginal and/or transabdominal ultrasound.

Following successful completion of the Screening period study participants will be randomized to Treatment Group A, B, or C and will attend visits monthly (ie, every 4 weeks). Safety will be assessed throughout the study by monitoring adverse events, vital signs, physical examinations, clinical laboratory tests, 12-lead electrocardiograms, and assessments of bone mineral density.

All patients completing the Week 24 visit, including women randomized to placebo, will be offered the opportunity to enroll in an open-label extension study in which all eligible patients will receive relugolix co-administered with low-dose estradiol and norethindrone acetate. Patients who do not enroll into the extension study will have a follow-up visit approximately 30 days after the end of treatment (ie, after the patient's last dose of study medication).

Primary Outcome Measures :
  1. Proportion of women who achieve a menstrual blood loss (MBL) volume of < 80 mL and a ≥ 50% reduction from Baseline MBL volume over the last 35 days of treatment [ Time Frame: from Baseline up to last 35 days of treatment anticipated to be up to 24 weeks ]
    MBL volume is measured using the alkaline hematin method. For the primary analysis the relugolix plus E2/NETA group will be compared with the placebo group.


Secondary Outcome Measures :
  1. Proportion of women with amenorrhea (no or negligible bleeding) [ Time Frame: from Baseline up to last 35 days of treatment anticipated to be up to 24 weeks ]
    Will be assessed using MBL volume measured using the alkaline hematin method and patient daily diary data.

  2. Change in bleeding and pelvic discomfort scale score [ Time Frame: from Baseline up to Week 24 ]
    Will be assessed with 3 questions (each with a five point scale ranging from 'Not at all' to 'A very great deal') related to menstrual bleeding and pelvic tightness/pressure.

  3. Change in MBL volume [ Time Frame: from Baseline up to Week 24 ]
    MBL volume is measured using the alkaline hematin method.

  4. Proportion of women with Baseline hemoglobin ≤ 10.5 g/dL who have an increase in hemoglobin > 2 g/dL [ Time Frame: from Baseline up to Week 24 ]
    Blood samples will be collected from participants for hemoglobin measurements.

  5. Proportion of women with maximum pain score ≥ 4 during the last 35 days before randomization whose maximum pain score decreased to ≤ 1 over the last 35 days of treatment [ Time Frame: from Baseline up to Week 24 ]
    Pain will be assessed with a daily diary using a Numerical Rating Scale score (11-point scale) for uterine fibroid-associated pain.

  6. Change in uterine volume [ Time Frame: from Baseline up to Week 24 ]
    Volume of the uterus will be measured by transvaginal or transabdominal ultrasound.

  7. Change in primary fibroid volume [ Time Frame: from Baseline up to Week 24 ]
    Volume of the primary fibroid will be measured by transvaginal or transabdominal ultrasound.

  8. Time to MBL response [ Time Frame: up to 24 weeks ]
    Defined as the time to achieve a MBL volume of < 80 mL and a ≥ 50% reduction from Baseline MBL volume as measured by the alkaline hematin method.

  9. Change from baseline in MBL volume by visit [ Time Frame: up to 24 weeks ]
    Assessed by the alkaline hematin method.

  10. Change in impact on quality of life [ Time Frame: from Baseline up to Week 24 ]
    Assessed using the UFS-QoL Questionnaire.

  11. Change in Patient Global Assessment (PGA) for symptoms [ Time Frame: from Baseline up to Week 24 ]
    The PGA for symptoms is a 1-item questionnaire designed to assess participants impression of the severity of their symptoms related to uterine fibroids.

  12. Change in PGA for function [ Time Frame: from Baseline up to Week 24 ]
    The PGA for function is a 1-item questionnaire designed to assess participants impression of how their symptoms related to uterine fibroids affected their usual activities.

  13. Change in Bone Mineral Density (BMD) [ Time Frame: from Baseline up to Week 24 ]
    Assessed by dual-energy X-ray absorptiometry (DXA) scan.

  14. The number and percentage of participants with adverse events (AEs) as a measure of safety and tolerability [ Time Frame: up to 24 weeks ]
    Assessed by frequency and severity of AEs and serious AEs.

  15. Pharmacokinetics of relugolix, estradiol and norethindrone acetate [ Time Frame: up to 24 weeks ]
    Blood samples will be collected from participants for measurement of relugolix, estradiol and norethindrone concentrations.

  16. Change in serum concentrations of luteinizing hormone (LH), follicle-stimulating hormone (FSH), estradiol (E2) and progesterone (P) [ Time Frame: up to 24 weeks ]
