Phase 1

Study Type: Interventional

Endpoint Classification: Safety Study
Intervention Model: Parallel Assignment
Masking: Open Label
Official Title: An Open-label, Two-stage, Dose-escalation, Parallel Group Study to Evaluate the Safety and Pharmacokinetics Profile of Proellex® (CDB-4124) in Female Patients With Impaired Hepatic Function and Healthy Adult Volunteers

Further study details as provided by Repros Therapeutics Inc.:

Primary Outcome Measures:
  • To compare the safety profile of a single dose of 25mg and 50mg of Proellex® in female patients with impaired hepatic function and in volunteers with normal hepatic function. [ Time Frame: 3 days ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • To determine and compare the pharmacokinetics (PK) of a single dose of 25mg and 50mg of Proellex® in female patients with impaired hepatic function and in volunteers with normal hepatic function. [ Time Frame: 3 days ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 16
Study Start Date: October 2008
Study Completion Date: June 2009
Primary Completion Date: May 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: A
Proellex 25 mg in healthy females
Drug: Proellex
Proellex 25 mg capsule, single dose
Experimental: B
Proellex 50 mg in hepatically impaired females
Drug: Proellex
Proellex 2, 25 mg capsules, single dose

Detailed Description:

16 subjects will be allocated to 2 groups. The test group will consist of 8 female patients with moderately impaired hepatic function meeting the Child-Pugh Class B severity criteria, while the control group will consist of 8 healthy female adult volunteers. During Stage I, all subjects will receive a single oral dose of 25mg of Proellex® (fasting state) and be followed in a Clinical Research Unit (CRU) for about three days. Only subjects who do not experience serious adverse events (SAEs) or adverse events (AEs) that are determined by Investigator to be possibly, probably or definitely related to the treatment will participate in Stage II. The dose will be increased to a single dose of 50mg of Proellex® (fasting state) and subjects will be followed in a Clinical Research Unit (CRU) for about three days. Subjects will undergo blood draws at several time points.
