Inclusion criteria
Inclusion criteria: 1. Completed 24 weeks of study drug treatment and study participation in either MVT-601-3101 or MVT-601-3102; 2. Has voluntarily signed and dated the informed consent form prior to initiation of any study-specific procedures for MVT-601-3103; Note: Procedures conducted as part of the parent study that also serve as baseline procedures for this study will be done under the informed consent for the parent study. 3. Is not expected to undergo gynecological surgery or other surgical procedures for treatment of endometriosis (including ablation, shaving, or excision) during the study, including during the Follow-Up Period, and the patient does not desire such treatment during this time frame; 4. Has a negative urine pregnancy test at the Week 24/Baseline visit; 5. Has agreed to continue to use only study-specified analgesic medications during the study and is not known to be intolerant to these; 6. Agrees to continue to use acceptable nonhormonal contraceptive methods as described in Section 4.6 consistently during the Open-Label Treatment Period and for at least 30 days after the last dose of study drug. However, the patient is not required to use the specified nonhormonal contraceptive methods if she: a. Has a sexual partner(s) who was vasectomized at least 6 months prior to the Week 24/Baseline visit; b. Had a bilateral tubal occlusion (including ligation and blockage methods such as Essure™), at least 6 months prior to the Week 24/Baseline visit (patients with Essure must have prior confirmation of tubal occlusion by hysterosalpingogram) and there must be no evidence of post-Essure syndrome; c. Has a nonhormonal intrauterine device (eg, Paragard®) placed in the uterus; d. Is not sexually active with men; periodic sexual relationship(s) with men requires the use of nonhormonal contraception as noted above; e. Practices total abstinence from sexual intercourse, as her preferred lifestyle; periodic abstinence is not acceptable. Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range 800 F.1.3 Elderly (>=65 years) no F.1.3.1 Number of subjects for this age range
Exclusion criteria
Exclusion criteria: Exclusion Criteria: None of the following criteria may be true for a patient to be eligible for enrollment into this study. 1. Has had a surgical procedure for treatment of endometriosis at any time during the parent study (MVT-601-3101 or MVT-601-3102); 2. Has any chronic pain or frequently recurring pain condition, other than endometriosis, that is treated with opioids or requires analgesics for = 7 days per month; 3. 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 (eg, bilateral hip replacement, spinal hardware in the lumbar spine); 4. Has a Z-score 2.0 times the upper limit of normal (ULN); or b. Bilirubin (total bilirubin) > 1.5 x ULN (or > 2.0 x ULN if secondary to Gilbert syndrome or pattern consistent with Gilbert syndrome); 10. Is currently pregnant or lactating, or intends to become pregnant during the study period or within 1 month after the last dose of study drug, or plans to donate ova during the study period or within 2 months after the last dose of study drug; 11. The presenting visual acuity score has decreased by 10 or more points at the Week 24/Baseline visit relative to the parent study Baseline visit; Note: Visual acuity score must have been obtained with corrective lenses, if applicable. 12. Is inappropriate for participation in this study because of conditions that may interfere with interpretation of study results or prevent the patient from complying with study requirements, as determined by the investigator, sub-investigator, or medical monitor; 13. Met a withdrawal criterion in the parent study (MVT-601-3101 or MVT-601-3102).

| Main Objective: To evaluate long-term efficacy of relugolix 40 mg once daily co administered with low-dose estradiol and norethindrone acetate for up to 52 and 104 weeks, among patients who previously completed a 24-week treatment period in one of the parent studies (MVT-601-3101 or MVT 601-3102), on endometriosis-associated pain.;Secondary Objective: To evaluate long-term efficacy of relugolix 40 mg once daily co-administered with low-dose estradiol and norethindrone acetate at week 52 and week 104, among patients who previously completed a 24-week treatment period in one of the parent studies MVT-601-3101 or MVT 601- 3102, on the following: - Function, as measured by the EHP-30 Pain Domain; - Dysmenorrhea, as measured by the NRS for dysmenorrhea; - PGIC for dysmenorrhea; - NMPP, as measured by the NRS for NMPP; -Overall pelvic pain, as measured by the NRS -Analgesic use - PGIC for NMPP; - Dyspareunia, measured by the NRS; - PGIC for dyspareunia; - Dyspareunia-related functional effects (sB&B); -To determine the benefit of relugolix 40 mg once daily co-administered with 24 weeeks of low-dose estradiol and norethindrone acetate compared with placebo on function measured by the EHP-30 Pain Domain - PGA for pain; - PGA for function; - Endometriosis-associated quality of life, as measured by the EHP-30 ;Primary end point(s): Primary Efficacy Endpoints - Proportion of women who respond or maintain response at Week 52 and 104/Early Termination, based on their dysmenorrhea NRS scores; - Proportion of women who respond or maintain response at Week 52 and 104/Early Termination, based on their NMPP NRS scores. - Percent change from the parent study Baseline in bone mineral density at the lumbar spine (L1-L4), total hip, and femoral neck as assessed by DXA;Timepoint(s) of evaluation of this end point: Week 52 and 104 (week 28 considering the extension study alone)/Early Termination. | — |
