Novozymes A/S Grants CSL Behring an Exclusive License to its Albumin Fusion Technology, albufuse(TM)

Nottingham (UK) and King of Prussia, PA (U.S.) CSL – March 31st 2008, Novozymes announced it has signed an exclusive worldwide licensing agreement for its propriety albumin fusion technology, albufuse™ with CSL Behring. albufuse™ technology has been proven to extend the circulatory half-life of therapeutic proteins through genetic fusion to recombinant human albumin. The license will enable CSL Behring to use albufuse™ technology for research, development and commercialization of novel biotherapeutic products.

CSL Behring has chosen albufuse™ technology because it has been shown to increase the circulatory half-life of a wide range of therapeutically relevant proteins, leading to increased bioavailability and therefore less frequent administration. The combined expression and production process eliminates the need for additional post-production chemical derivatisation, such as PEGylation, making albufuse™ technology the natural choice for protein half-life extension. Pre-clinical studies have demonstrated albufuse™ efficacy with a number of therapeutically relevant proteins.

“We have chosen Novozymes’ albufuse™ as we believe it offers unique product and patient benefits to enhance our current protein therapeutic pipeline. As we recently presented at the meeting of the American Society of Hematology, results from recent pre-clinical studies are encouraging,” commented Val Romberg, Senior Vice President of R&D at CSL Behring.

Pre-clinical data presented at the American Society of Hematology 49th Annual Meeting and Exposition suggests that fusion of Factor VIIa (FVIIa) to recombinant human albumin, using albufuse™, significantly extends the circulatory half-life of the protein. In the study, the fusion protein (rVIIa-FP) was shown to extend the half-life of the recombinant protein 6-to-9 fold compared to wild type (rFVIIa). Additionally, rVIIa-FP demonstrated a biologic activity comparable to wild type rFVIIa. Recombinant factor VIIa (rFVIIa) is used to control bleeding episodes in hemophilia patients.

Dr. David Mead, Novozymes Business Development Director in the UK commented: “We are delighted to have an opportunity to work with CSL Behring. This license further demonstrates Novozymes’ long-term commitment to becoming a strategic partner to the global pharmaceutical industry. The applications of albufuse™ technology are substantial and growing, with one of our licensee’s initiating a Phase III clinical trial with their interferon based fusion candidate. We are confident that the license with CSL Behring will further demonstrate that albufuse™ is a key technology for drug development.”
