Fresenius Biotech and Nabi Biopharmaceuticals sign agreement for the clinical development and the marketing of ATG Fresenius S in the U.S.

Fresenius Biotech and Nabi Biopharmaceuticals (Nasdaq: NABI) have signed an agreement to advance the ongoing clinical development of the immuno-suppressant ATG-Fresenius S for the U.S. market. The agreement also grants Nabi Biopharmaceuticals exclusive sales and distribution rights in North America for ATG-Fresenius S for up to 15 years following approval by the U.S. Food and Drug Administration (FDA). Nabi Biopharmaceuticals will be responsible for the clinical development, regulatory approval, marketing and sales in the U.S. Fresenius Biotech will receive milestone and licensing payments and supply ATG-Fresenius S to Nabi Biopharmaceuticals.

Dr. Thomas Gottwald, CEO of Fresenius Biotech: "We are very pleased to have found an experienced partner in transplantation medicine that can continue and expand the current clinical development program of ATG-Fresenius S. Nabi Biopharmaceuticals created what today is a very favorable commercial product in Nabi-HB, the current gold standard in the U.S for prevention of re-infection with hepatitis B in liver transplant patients."

In January of this year, Fresenius Biotech announced that it would continue the clinical development program with another partner after Enzon Pharmaceuticals had terminated its Licensing Agreement with Fresenius Biotech. Enzon had decided to redirect its research and development investments.

ATG-Fresenius S is an immuno-suppressive polyclonal antibody and is used for the induction of immuno-suppression and rescue therapy of acute rejection following solid organ transplantation. Fresenius Biotech currently markets the drug in more than 60 countries.
