Albuferon

From WikiCover

Albuferon is a novel long-acting form of interferon alpha created by HGS using its proprietary albumin fusion technology. Albuferon results from the genetic fusion of human albumin and interferon alpha. Human albumin is the most prevalent naturally occurring blood protein in the human circulatory system, persisting in circulation in the body for more than 20 days. Research shows that genetic fusion of therapeutic proteins to human albumin decreases clearance and prolongs the half-life of the proteins. Recombinant interferon alpha is approved for the treatment of hepatitis C, hepatitis B and a number of cancers.

On August 28, 2007, Human Genome Sciences announced that it will receive a $40 million payment from Novartis in September 2007 for the previously reported successful completion of a Phase 2b trial of Albuferon (albinterferon alfa-2b) in treatment-naive patients with chronic hepatitis C.

Under a co-development and commercialization agreement entered into in June 2006, HGS and Novartis will co-commercialize Albuferon in the United States and will share clinical development costs, U.S. commercialization costs and U.S. profits equally. Novartis will be responsible for commercialization in the rest of the world and will pay HGS a royalty on those sales. Clinical development, commercial milestone and other payments to HGS could total as much as $507.5 million, including $92.5 million received to date and the $40 million payment expected in September 2007.
