UPDATE: Aeterna Zentaris to Discontinue Phase 3 Trial in Multiple Myeloma with Perifosine

Aeterna Zentaris Inc.

today announced that an independent Data Safety Monitoring Board ("DSMB") has recommended discontinuing the ongoing Phase 3 study comparing the efficacy and safety of perifosine to placebo when combined with bortezomib (Velcade(®)) and dexamethasone in patients with relapsed or relapsed/refractory multiple myeloma. Based on the outcome of its pre-planned interim analysis of efficacy and safety, the DSMB recommended that patient enrollment be stopped and the study discontinued. The DSMB reported that it was highly unlikely the study would achieve a significant difference in its primary endpoint, progression free survival; no safety concerns were raised. Juergen Engel, PhD, Aeterna Zentaris President and CEO stated, "We are obviously disappointed with the outcome of the interim analysis as reported to us by the DSMB, both from a patient and Company perspective. However, we remain focused on other significant opportunities such as our Phase 3 trial in endometrial cancer and Phase 2 trials in breast, prostate and bladder cancer with AEZS-108, our NDA filing for AEZS-130 as an oral diagnostic test for growth hormone deficiency in adults, as well as our earlier-stage oncology compound, AEZS-120."
