360The purpose of this study is to evaluate the effectiveness and safety of 2.5, 5 and 10 mg doses of mifepristone against a placebo in women with laparoscopic diagnostic of endometriosis.
The hypothesis of the study is that the 5 mg mifepristone dose is safe and effective and should be used in future studies on medical treatment of endometriosis.

Endometrial biopsy was performed if endometrial thickness as calibrated by ultrasound was >8 mm or if there had been abnormal bleeding in the past 3 months. After 90 and 180 days of treatment an ultrasound examination of the pelvis was carried out and then followed by diagnostic-therapeutic laparoscopy and endometrial biopsy.
