May 29, 2019 updated by: Repros Therapeutics Inc.

A Phase 2, Multi-Center, Parallel Design, Randomized, Double-Blind Study to Evaluate the Safety and Efficacy of 6 and 12 mg Proellex® (Telapristone Acetate) Administered Orally in the Treatment of Premenopausal Women With Confirmed Symptomatic Uterine Fibroids

The primary objective of this study is to determine the safety and efficacy of two oral doses of Proellex administered for up to 2 courses of treatment (18 weeks each), each separated by an Off-Drug Interval (ODI), to premenopausal women with symptomatic uterine fibroids.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants in Amenorrhea at the End of Treatment Course 1
Time Frame: At the end of 18-weeks Treatment Course 1
Amenorrhea was defined as no bleeding intensity score greater than 1 using the Daily Diary Card during the 28 days leading up to the last day of dosing at Week 18. Bleeding intensity was graded on a 5-point scale where: 0=no bleeding to 4=heavy bleeding.
At the end of 18-weeks Treatment Course 1

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants in Amenorrhea at the End of Treatment Course 2
Time Frame: At the end of 18-weeks Treatment Course 2
Amenorrhea was defined as no bleeding intensity score greater than 1 using the Daily Diary Card during the 28 days leading up to the last day of dosing at Week 18. Bleeding intensity was graded on a 5-point scale where: 0=no bleeding to 4=heavy bleeding.
At the end of 18-weeks Treatment Course 2
Change in Pictorial Blood Loss Assessment Chart (PBAC) Score From Baseline to the End of Treatment Courses 1 and 2, ODI Course 1 and the Course 2 Week 28 Follow-up (FU) Visit
Time Frame: Baseline (No treatment period) to the end of 18-weeks Treatment Course 1, the end of ODI Course 1, the end of 18-weeks Treatment Course 2 and the Course 2 Week 28 FU Visit
Uterine bleeding was assessed with the use of the PBAC, a validated self-reporting method to estimate menstrual blood loss. Participants recorded daily the number of tampons and towels used and the degree to which individual items were soiled with blood (plus small or large clots). Pictorial scores range from score 1 for slightly stained tampon/towel, 5 for a partially stained tampon/towel, 10 for a completely saturated tampon, 20 for a completely saturated towel, and 5 for each episode of flooding and for each blood clot larger than a quarter in size. Total score can range from 0 (no bleeding) to >500. Higher scores indicate more bleeding. Lower scores indicate less bleeding. A negative change from Baseline indicates improvement (reduction in bleeding).
