Summary
Brief summary
The purpose of this study is to evaluate the long-term efficacy and safety of relugolix 40 milligram (mg) once daily co-administered with low-dose estradiol (E2) and norethindrone acetate (NETA) for up to 104 weeks on endometriosis-associated pain in participants who previously completed a 24-week treatment period in one of the parent studies (MVT-601-3101 or MVT-601-3102).
