CHARLESTON, S.C.--(BUSINESS WIRE)--Aeterna Zentaris Inc. (NASDAQ: AEZS) (TSX: AEZ) (the “Company”) today announced that the confirmatory Phase 3 clinical trial of Macrilen™ (macimorelin) failed to achieve its objective of validating a single oral dose of macimorelin for the evaluation of growth hormone deficiency in adults (“AGHD”), using the insulin tolerance test (the “ITT”) as a comparator. The Company is evaluating the outcome of the trial and will determine in the near future whether it will continue with the development of Macrilen™.
Dr. Richard Sachse, the Company’s Chief Scientific Officer, stated, “We are, of course, very disappointed about the outcome of the trial. Based on an analysis of top-line data, macimorelin did not achieve equivalence to the ITT as a means of diagnosing AGHD. Under the study protocol, the evaluation of AGHD with Macrilen™ would be considered successful, if the lower bound of the two-sided 95% confidence interval for the primary efficacy variables was 75% or higher for “percent negative agreement” with the ITT, and 70% or higher for the “percent positive agreement” with the ITT. While the estimated percent negative agreement met the success criteria, the estimated percent positive agreement did not reach the criteria for a successful outcome. Therefore, the results did not meet the pre-defined equivalence criteria which required success for both the percent negative agreement and the percent positive agreement. After a thorough internal review and understanding of this data, the Company will decide upon the appropriate future course of action with respect to macimorelin.”
David A. Dodd, the President and Chief Executive Officer of the Company, stated, “While we are disappointed regarding the outcome of this trial, we will now re-direct our resources to the completion of the on-going Phase 3 clinical trial of Zoptrex™ in women with advanced, recurrent or metastatic endometrial cancer who have progressed and who have received one chemotherapeutic regimen with platinum and taxane (either as adjuvant or first-line treatment). Zoptrex™ represents a new targeting concept in oncology using a hybrid molecule composed of a synthetic peptide carrier and a well-known chemotherapy agent, doxorubicin. It is the first drug in advanced clinical development that is considered to direct the chemotherapy agent specifically to LHRH-receptor expressing tumors, which then could result in a targeted treatment with less damage to healthy tissue. Potential benefits of this targeted approach include better efficacy and a more favorable safety profile with lower incidence and severity of side effects as compared to doxorubicin alone. We look forward to reporting the results of this trial in the very near future.”
The Company will host a conference call to discuss the results of the confirmatory Phase 3 clinical study of Macrilen™ on Thursday, January 5, 2017, at 8:30AM, Eastern Time. Participants may access the conference call by using the following number: 201-689-8029, Confirmation 13651438.
