LOGO OF AETERNA LABORATORIES INC. P R E S S R E L E A S E FOR IMMEDIATE RELEASE AETERNA REPORTS ON ITS PIVOTAL PHASE II TRIAL ON MULTIPLE MYELOMa PATIENT RECRUITING IS UNDER WAY IN 35 INVESTIGATIVE CENTRES IN NORTH AMERICA AND EUROPE BANFF, ALBERTA, MAY 8, 2001 - AEterna Laboratories Inc. (NASDAQ: AELA; TSE: AEL) confirmed today that patient recruiting for the pivotal Phase II trial on progressive multiple myeloma continues in some 35 investigative centres in Canada, the U.S., and Europe. Led by an international team of oncology experts, the study is advancing according to schedule, and aims at evaluating the efficacy of Neovastat as a monotherapy treatment for some 120 patients who do not respond to standard therapies. In December 2000, U.S. and Canadian health authorities gave AEterna the green light to undertake this study, and in the following March, European authorities followed suit. Results of the study are expected before the end of 2002. This announcement was made by Dr. Kenneth C. Anderson, Professor of Medicine of the Harvard Medical School, Medical Director of the Oncology Department of the Dana-Farber Cancer Institute of Boston and member of AEterna's Scientific Advisory Board, during the Eighth International Conference on Multiple Myeloma held in Banff, Alberta. "The results of this study are very important because they would allow to offer an innovative treatment to patients with progressive multiple myeloma, for which existing treatments are quite limited," emphasized Dr. Anderson. "Thanks to its multiple mechanisms of action, Neovastat is able to target the elements involved in the progression of the disease." "We highly consider the interest that Neovastat development has created within the international medical community, and we are proud to have obtained the collaboration of recognized experts in both North America and Europe to help us successfully complete our three ongoing clinical trials," added Dr. Claude Hariton, Vice President, Clinical and Regulatory Affairs of AEterna. "These trials on the European continent fit perfectly into our strategy of expanding AEterna's activities on an international scale." "By pinpointing some specific cancers like multiple myeloma and renal cell carcinoma, for which a restricted number of therapies are currently available, and by carefully respecting our development timeline, we are increasing the possibility of being among the first to bring an angiogenesis inhibitor to the market," concluded Gilles Gagnon, Vice President and Chief Operating Officer of AEterna. In North America, the principal investigators are Dr. Sundar Jagannath, Professor of Medicine at St. Vincent's Comprehensive Cancer Center, New York, in the U.S., and Dr. Chaim Shustik, Associate Professor of Medicine at McGill University and the Royal Victoria Hospital, in Montreal, Canada. The principal investigator in Europe is Dr. Jean-Paul Fermand, Professor of Medicine and Head of the Immuno-Hematology Unit of the St. Louis University in Paris, France. ABOUT MULTIPLE MYELOMA Multiple myeloma is a cancer of blood cells that arises in the bone marrow. This disease accounts for 1% of all cancers and is the second most prevalent blood cancer. In the U.S., approximately 50,000 persons are affected by the disease. There are about 14,000 new cases of multiple myeloma in North America each year and about 18,000 new cases in the countries of the European Community, and the five-year mortality rate is approximately 75%. Standard medical treatments such as chemotherapy, radiation therapy, and bone marrow transplantation enable patients diagnosed with multiple myeloma to live an average of four years. These therapies are often associated with a large number of serious side effects.
