Outcome Measures
Primary Outcomes (2)
Percentage Of Participants Who Meet The Dysmenorrhea Responder Criteria At Week 24 Or End Of Treatment (EOT)
Assessed using a Numerical Rating Scale (NRS) score (11-point scale) for pain recorded daily in an electronic diary (e-Diary). The criteria for a responder was based on a pre-defined threshold and accounted for analgesic use.
Week 24 or EOT
Percentage Of Participants Who Meet The Non-Menstrual Pelvic Pain (NMPP) Responder Criteria At Week 24 Or EOT
Assessed using an NRS score (11-point scale) for pain recorded daily in an e-Diary. The criteria for a responder was based on a pre-defined threshold and accounted for analgesic use.

Interventions
Relugolix 40-mg tablet administered orally once daily.
Capsule containing co-formulated tablet of E2 (1.0 mg)/NETA (0.5 mg) administered orally once daily.
