Repros Therapeutics Inc. Announces That United States Food and Drug Administration Places Proellex® On Clinical Hold

THE WOODLANDS, Texas--(BUSINESS WIRE)--Repros Therapeutics Inc. (NasdaqGM:RPRX) announced today that the Company received verbal notice on August 4, 2009 from the United States Food and Drug Administration (FDA) during a teleconference, requested by and held later that day with the Agency, that the Company's Investigational New Drug Applications (INDs) for Proellex have been placed on clinical hold for safety reasons. This action follows the Company's voluntary decision to suspend dosing of all patients in its clinical trials of Proellex (see press release dated August 3, 2009).

The Company and the FDA are scheduled to discuss the safety of Proellex and the overall direction and scope of the Company's clinical trials of Proellex at a meeting in late September. The FDA requested that the Company provide it with weekly updates about the patients who experienced a serious adverse event and still have elevated liver enzymes. The Company plans to provide such information as requested. In addition, at the September meeting Repros intends to present a detailed analysis of all of the patients with elevated liver enzymes, discuss the events that led to the suspension of the clinical trials, and determine whether and under which conditions, if any, the clinical hold may be lifted and the clinical trials of Proellex be safely resumed.
