Participants with endometriosis
Premenopausal participants with endometriosis receiving elagolix in real-world setting
|
- Change in Dysmenorrhea Score [ Time Frame: From Baseline (Month 0) to Month 6 ]Dysmenorrhea is evaluated through 11-point numeric rating scale (NRS), where 0 = no pain and 10 = worst imaginable pain
- Percentage of Participants With Patient Global Impression of Change (PGIC) Response [ Time Frame: Up to approximately 18 months ]PGIC 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) Response [ Time Frame: Up to approximately 18 months ]CGIC score is summarized assessment of clinical diagnosis of patient's illness by clinician in relative to a baseline state.
