Clinical Study to Evaluate Efficacy and Safety of TAK-385 40 mg Compared With Leuprorelin in Patients With Endometriosis

2019-05-05 16:45:34 | BioPortfolio


The objective is to evaluate the efficacy and safety of TAK-385 40 mg orally administrated once daily for 24 weeks compared with Leuprorelin [once/4 weeks, 3.75 or 1.88 mg subcutaneously (SC)/time] in patients with endometriosis.


This study is a phase III, multicenter, randomized, double-blind, parallel-group study to investigate the efficacy and safety of TAK-385 40 mg once daily compared with leuprorelin (once/4 weeks, 3.75 or 1.88 mg SC/time) in premenopausal subjects ≥ 20 years of age with endometriosis. 320 women with endometriosis will be enrolled in the study. This study consists of screening of approximately 1 to 6 weeks, run-in of approximately 3 to 6 weeks, treatment of 24 weeks, and follow-up of 4 weeks. After signing the informed consent form, subjects should record their symptoms in the electronic patient diary every day. During run-in period, daily data will be collected in the electronic patient diary for calculation of the baseline values for the efficacy evaluation.Following run-in period, subjects will receive investigational products (TAK-385 + leuprorelin placebo or TAK-385 placebo + leuprorelin) under double blind. During this study, subjects will visit the study center to undergo the designated examinations and evaluations at each visit. Safety will be assessed throughout the study by monitoring adverse events, vital signs, physical examinations, clinical laboratory tests, 12-lead electrocardiograms (ECG), and assessments of bone mineral density.Subjects will visit the study center to undergo the designated examinations and evaluations at 28 days after final administration.
