Design outcomes

Primary

MeasureTime frameDescription
Change in Dysmenorrhea ScoreFrom Baseline (Month 0) to Month 6Dysmenorrhea is evaluated through 11-point numeric rating scale (NRS), where 0 = no pain and 10 = worst imaginable pain

Secondary

MeasureTime frameDescription
Percentage of Participants With Patient Global Impression of Change (PGIC) ResponseUp to approximately 18 monthsPGIC is a questionnaire-based assessment of endometriosis-related pain is since initiation of study drug.
Percentage of Participants With Clinician's Global Impression of Change (CGIC) ResponseUp to approximately 18 monthsCGIC score is summarized assessment of clinical diagnosis of patient's illness by clinician in relative to a baseline state.
