Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study was to determine the long-term efficacy and safety of relugolix 40 milligrams (mg) once daily co-administered with estradiol (E2) and norethindrone acetate (NETA) for 28 weeks on heavy menstrual bleeding associated with uterine fibroids in participants who previously completed a 24-week treatment period in one of the pivotal studies (MVT-601-3001 or MVT-601-3002).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study is an international phase 3 open-label, single-arm, long-term efficacy and safety extension study that enrolled eligible participants who have completed their participation in one of the phase 3 randomized, double-blind, placebo-controlled pivotal studies, MVT-601-3001 (LIBERTY 1 - NCT03049735) or MVT-601-3002 (LIBERTY 2 - NCT 03103087). All participants received relugolix 40 mg orally once daily co-administered with E2 (1 mg) and NETA (0.5 mg) for 28 weeks.

Approximately 600 women with heavy menstrual bleeding associated with uterine fibroids were to be enrolled, after having completed a 24-week treatment period in one of the pivotal studies. The objectives of the study were to evaluate long-term efficacy and safety through up to 52 weeks of treatment (including treatment during the pivotal study) of relugolix co-administered with E2/NETA.

Screening and baseline procedures were to be done at the same visit for this extension study (referred to as the "Week 24/Baseline Visit"), which coincided with the Week 24 Visit from the pivotal study and was to be defined as the date of completion of the last Week 24 procedure in the pivotal study. Participants will have received their last dose of study drug in the pivotal study on the day prior to the Week 24/Baseline Visit and were to receive their first dose of study drug for this extension study in the clinic after the participant was determined to be eligible for this extension study and provided informed consent to participate. The administration of the first dose of study drug for MVT-601-3003 was to define enrollment into this study. Study participants were to then take the open-label study treatment orally once daily for 28 weeks.
