Merck Serono and F-Star to Collaborate in the Discovery and Development of Novel Targeted Biologics

GENEVA, Switzerland, September 7, 2011 -

Merck Serono, a division of Merck KGaA, Darmstadt, Germany, announced today that a research, license and commercialisation agreement was signed with F-Star GmbH, Vienna, Austria, for the discovery of new antibody-derived therapeutics against inflammatory disease targets, using F-Star’s Modular Antibody Technology.

Under the terms of the agreement, Merck Serono will nominate up to three therapeutic targets and the parties will collaborate to jointly discover mono-specific Fc-based targeted biologics (Fcabs) and bi-specific IgG-based targeted biologics (mAb²) for which Merck KGaA will have exclusive worldwide development and commercialisation rights. F-Star will receive an initial technology access fee and research-based funding and is eligible to receive additional license fees, development, regulatory and commercialisation milestones which in aggregate could reach € 492 million, as well as undisclosed tiered royalties on product sales. Further details of the agreement were not disclosed.

“We are very pleased to see our investment in F-Star through Merck Serono Ventures mature into a strategic collaboration, which reinforces our commitment to deliver innovative treatments in the area of inflammatory diseases,” said Susan Herbert, Head of Portfolio Development at Merck Serono. “We believe that F-Star’s Modular Antibody Technology has the potential to offer important functional advantages over conventional antibodies and will potentially allow us to generate highly differentiated drugs for patients with so far unmet medical needs.”

Dr Kevin FitzGerald, Chief executive officer of F-Star, commented, “We are very pleased to have completed this agreement with Merck Serono. Merck Serono Ventures has proved to be a supportive venture investor in F-Star and we are now excited to expand the relationship with Merck Serono to include collaborative discovery and development projects. F-Star has developed novel technology for the discovery of targeted biologics that offer significant improvements over conventional antibodies. This agreement builds on F-Star’s strategy to develop and demonstrate the therapeutic potential of our proprietary technology through advancing our own pipeline as well as through a limited number of very selective research collaborations.”

The company develops improved therapeutic antibodies and antibody fragments based on its Modular Antibody Technology, which allows the introduction of additional antigen-binding sites into antibodies and antibody fragments by engineering the non-CDR loops of antibody domains. Using Modular Antibody Technology F-Star generates antibody fragments that have full antibody functionality and long half-life but are much smaller in size (Fcab™) and full-sized antibodies with additional functionality or bispecificity (mAb²™). Since its founding in 2006 the company has raised approximately € 34 million from a syndicate comprising both venture and corporate investors: Atlas Venture, Aescap Venture, Novo Ventures, TVM Capital, Merck Serono Ventures, MP Healthcare Venture Management and SR One. The company employs 24 staff at its research sites in Vienna and Cambridge. For more information visit www.f-star.com.
