Study 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.

Read the 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 E2 and NETA (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 E2 and NETA (Group B) compared with 24 weeks of placebo (Group C).

All participants completing the Week 24 visit, including participants randomized to placebo, were offered the opportunity to enroll in an open-label extension study in which all eligible participants will receive relugolix co-administered with low-dose E2 and NETA. Participants who did not enroll into the extension study had a follow-up visit approximately 30 days after the end of treatment (that is, after the participant's last dose of study medication).

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.

What researchers measure

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.

    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.

Lower score indicates minimal symptom severity and higher score indicates symptom severity. 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

Outcome measures

PrimaryPercentage 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.

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.

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 symptom severity. 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

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jun 2017 to primary completion in Jul 2019, 24 months.

Results were first posted in Apr 2022, 2 years 9 months after primary completion. A results delay was requested in May 2020.

Of 18 phase 3 interventional studies under Menorrhagia, half reached primary completion within 27 months of starting (the median), counting those still running; a quarter within 24 and three quarters within 35. This study's 24 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 20, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
