Registration Number
NCT00874302
Lead Sponsor
Repros Therapeutics Inc.
Brief Summary

Subjects with symptomatic uterine fibroids will be enrolled and will receive daily oral study medication for 4 months. This will be followed by a 6 month off-drug interval until there is a return of significant symptomatology. If they experience symptoms of a certain severity, the subject will enter a second 4 month treatment cycle and then a follow-up period.

Detailed Description

Subjects with documented symptomatic uterine fibroids will be enrolled in the study. Following screening, subjects will receive daily oral study medication and will be assessed monthly for a 4 month treatment cycle. This first cycle will be followed by an off-drug interval until there is a return of significant symptomatology. Subjects will be followed for up to six (6) months post-treatment. If their lack of symptoms does not qualify them for a second cycle of treatment, they will be discharged from the study. If they experience symptoms of a certain severity, the subject will enter a second 4 month treatment cycle and then a follow-up period.
