Enrollment: 71
Healthy volunteers: no

Brief summary:
Premenopausal women with symptomatic uterine fibroids will be randomized to either Proellex 25mg or 50mg or placebo for one treatment cycle (four months). Safety and effectiveness between 50 mg versus placebo, and between 25mg and placebo will be analyzed.

Detailed description:
Subjects with documented uterine fibroids, screening UFS-QOL severity score of at least 40, and meeting other eligibility criteria will be enrolled in the study. Following screening and a pre-treatment endometrial biopsy, subjects will be assessed monthly for the four (4) month double-blinded treatment phase. The study duration is approximately six months, comprised of a one-month screening period, 4 month treatment period and one month follow-up period. Subjects' blood will be drawn in a fasting state to obtain the pre-dose trough (PK) levels of study drug at each study drug dosing/dispensation visit to determine the potential for drug accumulation.
