About this study
Official title: A Single-Blind, Placebo Run-in, Phase I/II Study Comparing Five Oral Doses of Proellex®
The purpose of this study is to determine the effects of five different doses of Proellex on menses, ovulation, liver function, and steady state exposure in women of reproductive age.
Read the detailed description
A phase I/II, 5 arm, single blind study, comparing five doses of Proellex to matching placebo in healthy adult female subjects of reproductive age. Exposure to study drug will be for up to 10 weeks. In-clinic pharmacokinetic (PK) assessments will be made on the first day of dosing and on the last day (week 10). Office visits will occur every week to assess liver function and trough blood concentrations for Proellex and primary metabolite. Daily vaginal bleeding diaries will be maintained during the course of the study. A single blind run-in period of up to 56 days will begin the study to assess baseline menstrual patterns will be utilized. Twelve subjects per treatment group (total 60 subjects) will be assigned to each dose. New groups will not begin dosing until the previous dose group has completed. Daily treatments will be either 1 mg, 3 mg, 6 mg, 9 mg, 12 mg Proellex. A single blind run-in period using placebo will be incorporated to establish baseline parameters.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Proellex in people with Amenorrhea, run by Repros Therapeutics Inc. at 1 site 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 14 inclusion and 11 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: finished, as of the sponsor's last update on 28 Jul 2014. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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 28 Jul 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?
Induction Amenorrhea (time frame: 10 weeks). 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 28 Jul 2014.
