Phase 2
Completed
Conditions
Endometriosis
Interventions
Registration Number
NCT01767090
Lead Sponsor
Astellas Pharma Europe B.V.
Brief Summary

The main objective for this study is to assess the efficacy and dose-response relationship of ASP1707 in reduction of endometriosis associated pelvic pain. The secondary objectives are to assess the safety, tolerability, Pharmacokinetics of ASP1707, dose response relationship of ASP1707 in reduction of E2 (Estradiol), 24-week efficacy of ASP1707 in reduction of endometriosis associated pain and 24-week safety and tolerability of ASP1707.
