A Phase 2, Three-arm, Parallel Design, Randomized, Double-Blind Study to Evaluate the Safety, Pharmacokinetics and Efficacy of Proellex® (Telapristone Acetate) Administered Vaginally in the Treatment of Premenopausal Women With Uterine Fibroids Confirmed by Ultrasound
This study is a phase II, 3 arm study with a 12 week active dosing period. The study will
be conducted in 2 stages. In the first stage, the first 6 women to be enrolled will be
treated at the 12mg dose level, and in addition to the other required study assessments will
be monitored with a 24-hour PK assessment on Day 14, and daily trough assessments for the
first 14 days. If, at Visit 3, the Cmax or AUC of any subject treated at 12mg exceeds the
mean observed for the highest safe oral dose administered in the ZP-204 study, all subjects
enrolled at the 12mg level will be discontinued, no further patients will be treated at this
dose level, and the 6mg vaginal dose will be assessed in a similar fashion. In the second
stage, the remaining subjects will be randomized to a dose of 3, 6 or 12 mg.
For all subjects there will be a 4-6 week placebo run-in period, to establish baseline
parameters (bleeding and quality of life) followed by treatment at one of three single-blind
Proellex doses (3, 6 or 12 mg daily, administered vaginally in capsule form.) The primary
efficacy endpoint will be bleeding assessed using the PBAC after 12 weeks of treatment. The
secondary endpoints will be changes in size of uterine fibroids assessed by MRI and
improvement in quality of life assessed using the UFSQOL. Safety endpoints include
significant adverse events, changes in physical examination results, and/or clinical
laboratory results significantly outside of normal range. For subjects enrolled in Stage 2,
PK will be assessed after the first and last doses and trough levels every 2 weeks.
