Debiopharm S.A. announces the purchase of all outstanding shares of H3 Pharma

Lausanne, Switzerland, March 1, 2005 – Debiopharm S.A., the independent drug development company specialising in oncology, endocrinology and niche products, announced today that it has purchased all the outstanding shares of H3 Pharma from Montreal-based Société Générale de Financement du Québec (SGF).

H3 Pharma is a drug development company that was created in Montreal in June 2001, as the result of an equal partnership between SGF and the Debio Group. Since then, H3 Pharma has undergone an additional recapitalisation and holds shares in a German biotech company specialising in human antibodies for cancer therapy. Among H3 Pharma’s portfolio of products is Sanvar® , which in December 2004 received an approvable letter for its New Drug Application (NDA) from the US Food and Drug Administration (FDA). SC-1, a monoclonal IgM antibody with human data that targets CD55SC-1, a cell surface receptor that is specifically expressed on human gastric carcinoma cells, is another of H3 Pharma’s promising pipeline products.

“We had a good partnership with SGF and have learnt a lot from this experience,” said Rolland-Yves Mauvernay, President and CEO of Debiopharm. “We are happy with how H3 Pharma has developed over the last three years.”

Loïc Maurel, President and CEO of H3 Pharma added: “Debio has been an active shareholder of H3 Pharma since our inception. This positive move consolidates H3 Pharma’s objective to be a leading drug development company in the pharma industry. We look forward to working even more closely with the Debio companies.”
