  • Company Instructed to Request Lifting of Full Clinical Hold for Oral Proellex for the Treatment of Uterine Fibroids
  • Oral Study to be Conducted in Parallel to Vaginal Phase 2b Study

THE WOODLANDS, Texas, Nov. 4, 2013 (GLOBE NEWSWIRE) -- Repros Therapeutics Inc.® (Nasdaq:RPRX) today reported it has received guidance from the FDA regarding its clinical program for low dose oral Proellex in the treatment of uterine fibroids.

The Company currently has three open INDs for Proellex:

  • 70,535 - oral treatment of fibroids STATUS: Full Clinical Hold
  • 76,631 – oral treatment for endometriosis STATUS: Partial Clinical Hold and in Phase 2
  • 112,576 – vaginal treatment for fibroids STATUS: Initiating Phase 2b

The Company held a meeting with the FDA on October 31, 2013 to discuss "going forward" plans for low dose oral Proellex in the treatment of uterine fibroids and to lift the clinical hold. In 2007, data had been discussed with the FDA based on the efficacy of a 12mg dose. The earlier study showed highly statistically significant results in achieving clinically relevant improvements in menstrual bleeding as well as symptoms associated with tumor bulk via a previously validated quality of life instrument (UFSQOL).

During the meeting with the FDA, the Agency provided guidance to the Company for endpoints it believed to be acceptable for the treatment of uterine fibroids. The Agency instructed the Company to submit a request for lifting of the full clinical hold at the same time it submits a new protocol. The Company will follow FDA's recommendations and submit the protocol and full hold lift in a timely fashion.

The Company will use the same design for the vaginal Phase 2b study and expects to start the two studies in early 2014. The Company has accounted for the costs of these studies in its current budget and these studies will not change the projected cash burn rate for 2014.
