er Phase 3 efficacy study, being led by Prof. Frans M.J. Debruyne, M.D., Ph.D., from The Netherlands, will enroll approximately 400 patients in Europe. The third Phase 3 trial currently screening patients, is an open-label, single-armed multi-center safety study involving approximately 500 patients in both North America and Europe, and is being led by Joel Kaufman, M.D., Associate Clinical Professor of Urology, University of Colorado School of Medicine, Denver, Colorado, and Urology Research Options, Aurora, Colorado.

The primary endpoint for both North American and European efficacy studies is the change in I-PSS between baseline and Week 52.

The cetrorelix Phase 3 program is based on comprehensive clinical practice guidelines to ensure quality control, including input from expert advisors on study design, publishing results in peer-reviewed journals and discussion of the studies with regulatory agencies.
