Detailed Description

This is an open-label, randomized, single-center, outpatient, unblinded, single-dose, three-way crossover study of the safety and PK properties of Proellex® in women ages 18 - 34 years. Twelve female subjects will each receive a single dose of Proellex®: 25 mg (fed state, formulation A), 25 mg (fed state, formulation B), and 25 mg (fasting state, formulation B); successive dosing will be separated by at least one week intervals from the previous dosing. Blood will be collected prior to taking the dose, and following the dose for 24 hours post-dose. Subjects will be discharged from the study after the last blood sample is obtained after the third dose of Proellex®. Safety will be assessed throughout the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 34 years (ADULT)

Accepts Healthy Volunteers

Yes

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.
