Late stage development of PRX302 is supported by a successful randomized Phase IIb study with standard and well defined regulatory endpoints. PRX302 has shown meaningful improvements in the International Prostate Symptom Score (IPSS) and urinary flow rate (Qmax) at 3 and 6 months in this randomized, double-blind, placebo controlled Phase IIb trial (TRIUMPH). Prior to Phase III, 126 patients with BPH had been treated with PRX302, demonstrating an attractive safety profile including no drug-related erectile dysfunction adverse events. Enrollment into a Phase III clinical trial (PLUS 1) is ongoing.
IPSS has been a primary endpoint and Qmax has been a secondary (or co-primary) endpoint for the FDA approval of currently available drugs for the treatment of BPH.

A double-blind, multi-national, placebo controlled Phase III study targeting to enroll 440 patients with moderate to severe BPH. Patients will be randomized to PRX302 or placebo in this pivotal study. The primary endpoint of the study is to evaluate the 12-month safety and efficacy of PRX302. Enrollment into this study has initiated. For more information please see study NCT1966614 on www.clinicaltrials.gov.
