AEterna Laboratories Inc. (AELA) Subsidiary Zentaris AG (AELA) To Present Final Results From Phase I Trial Of Perifosine In Combination With Radiotherapy At 2004 American Society of Clinical Oncology Annual Meeting


10/19/2005 5:10:44 PM

QUEBEC CITY, April 7 /PRNewswire-FirstCall/ -- AEterna Laboratories Inc. (TSX: AEL; Nasdaq: AELA) along with its wholly-owned subsidiary Zentaris GmbH, announced today that results of the recently completed Phase I trial evaluating Perifosine, the Company's novel, first-in-class, oral AKT inhibitor in combination with radiotherapy in patients with unresectable locally advanced tumors will be presented at the upcoming American Society of Clinical Oncology (ASCO) Annual Meeting. The meeting will take place in New Orleans, LA, June 5 through 8, 2004. The lead investigator for the trial, Dr. Marcel Verheij, from the Department of Radiation of the Netherlands Cancer Institute of Amsterdam, will present the results.

The Phase I results to be presented at ASCO will form the basis for a Phase II trial evaluating Perifosine in combination with radiotherapy in patients selected for specific tumor types. Zentaris plans to evaluate Perifosine in combination with radiotherapy as a treatment for multiple types of cancer through the ongoing collaboration with the Netherlands Cancer Institute of Amsterdam.

The ongoing clinical development of Perifosine in North America includes nine Phase II trials in six cancer types that are being conducted through collaboration between Zentaris GmbH, Keryx Biopharmaceuticals Inc. and the United States National Cancer Institute (NCI). AEterna, through Zentaris GmbH, holds ex-North America rights to Perifosine. To date, five Phase I trials have been conducted on Perifosine, including the trial to be highlighted at ASCO. In the four preceding trials, use of Perifosine as a single agent in a total of 94 patients provided initial, encouraging evidence of anti-tumor activity. Namely, investigators observed two partial responses (greater than 50% reduction) in patients with sarcoma and sixteen stable disease in patients with breast, prostate, pancreatic and other forms of cancer.

Initial data from the Phase I trial undertaken by Dr. Verheij to evaluate the safety and tolerability, as well as to determine the maximum tolerated dose of Perifosine in the combination therapy regimen were reported in 2003 at the Second International Conference on Translational Research and Preclinical Strategies in Radiation Oncology (Lugano, Switzerland). Initial data in 7 patients with non-small cell lung cancer (NSCLC) and bladder cancer, who received Perifosine doses ranging from 50 to 100 mg/day concurrently with standard doses of radiotherapy, demonstrated acceptable tolerability. In addition, the combination regimen was not associated with bone marrow toxicity, an often treatment-limiting side effect associated with many cancer therapies currently on the market. The trial was continued with the goal to define the highest dose of Perifosine that is well tolerated in the combination regimen.
