Juergen Engel, Ph.D., AEterna Zentaris President and CEO stated, "Although the data received for the open-label safety study Z-041 with a nearly 6 point reduction in IPSS are in line with what we had observed in our Phase 2 program, we are disappointed by the failure to achieve the primary endpoint in the efficacy study Z-033. We remain committed to the ongoing Phase 3 program with cetrorelix in BPH and are working towards receiving the results of the second pivotal efficacy study Z-036 in November."
