About this study
Official title: A Phase III, Three-Arm, Parallel Design, Placebo-Controlled, Randomized, Double-Blind, Multicenter Study Evaluating the Safety and Efficacy of Proellex® (CDB-4124) in the Treatment of Premenopausal Women With Symptomatic Uterine Fibroids
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.
Read the 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.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Proellex in people with Uterine Fibroids, run by Repros Therapeutics Inc. at 17 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 21 Aug 2014. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 17 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 21 Aug 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
To Determine the Efficacy of 50 mg Proellex® Versus Placebo in the Treatment of Subjects With Symptomatic Uterine Fibroids From Baseline to Month 4 as Determined by Scoring Changes in the Pictorial Blood Loss Assessment Chart (PBAC) (time frame: 4 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Aug 2014.
