Repros Requests Meeting With FDA to Discuss Phase 3 Requirements for Proellex® in the Treatment of Symptomatic Uterine Fibroids

  • Focus on oral formulation
  • Phase II complete

THE WOODLANDS, Texas, Dec. 12, 2016 (GLOBE NEWSWIRE) -- Repros Therapeutics Inc.® (Nasdaq:RPRX) today announced it has requested a meeting to discuss Phase 3 requirements for the development of Proellex® (telapristone acetate) for the treatment of symptomatic uterine fibroids. The Company anticipates a meeting will be scheduled during the first half of 2017.

The Company has completed studies on both oral and vaginal delivery and will propose further development of the oral form of the drug. The objective of the meeting with the FDA is primarily to agree on the Phase 3 clinical program. To date, the Company has administered Proellex® at various doses and strengths in over 700 women. In efficacy studies of uterine fibroids the formulations of Proellex® have consistently exhibited both clinically and statistically significant reduction of excessive menstrual bleeding due to the presence of uterine fibroids. This clinical feature is due to the action of Proellex® which induces a state of amenorrhea (cessation of menses).  In addition to induction of amenorrhea, the studies have shown that Proellex® reduces fibroid volume which can significantly reduce the bulk symptoms many women with fibroids experience. 

The Company has also completed a thorough toxicity panel in animal models that meets ICH guidelines. This includes two successfully completed carcinogenicity studies. Of particular note, in the two year rat study, animals dosed with Proellex® exhibited a lower incidence of mammary tumors than control animals. 

The Company has also completed a full battery of drug interaction and special population studies, including a pilot QT interval study at significant multiples of the highest intended dose, 12 mg, that did not exhibit QT prolongation.

The current formulation of Proellex® allows for continuous dosing for up to 18 weeks which, is 50% longer than a competing product. In addition, the Proellex® studies have not demonstrated any apparent racial or BMI effect on overall efficacy.
