THE WOODLANDS, Texas--(BUSINESS WIRE)--Repros Therapeutics Inc. (NasdaqGM:RPRX) today announced that based on the robust efficacy demonstrated by Proellex® in the interim assessment of the Company’s Phase II endometriosis study, there are sufficient patients currently enrolled to provide for adequate power calculations for the Phase III endometriosis trials. Because of the profound effect noted in this interim analysis, the Company has decided to curtail further patient recruitment for the study. Based on this decision, greater than 40 patients will complete the four month study before yearend. The Company plans to request an end of Phase II meeting with the FDA before yearend and subsequently to commence the Phase III pivotal studies for Proellex in the treatment of endometriosis in the first half of 2009.
