Two (2) dose levels of Proellex or placebo will be administered once-daily for up to 91 days. Following screening and a pre-treatment endometrial biopsy, subjects will be followed monthly for the three month treatment phase. At the three-month treatment visit, subjects will be entered into an open-label extension treatment protocol, if deemed eligible. At four months after their first treatment visit, subjects not electing to enter the open-label study will be assessed at a final follow-up visit.
