Schlieren (Zurich), Switzerland & Singapore, December 16, 2010 – Switzerland's Cytos Biotechnology Ltd (SIX:CYTN) and Singapore's Agency for Science, Technology and Research (A*STAR) jointly announced today the extension of their existing collaboration for the development of a virus-like particle (VLP) based Influenza vaccine. Under this revised agreement, A*STAR will engage Cytos to develop, manufacture, and supply A*STAR with a Good Manufacturing Practice (GMP)-grade investigational vaccine candidate for a human proof-of-concept study in Singapore.

This extension follows an earlier Collaborative Research, Development and Commercialisation Agreement, signed by Cytos and A*STAR on 15th July 2010, to perform research, development and commercialization of a VLP vaccine to manage influenza infections. The objective of this agreement is to establish an independent supply of influenza vaccine for ASEAN and to extend Cytos' R&D pipeline. Cytos holds the worldwide, sub-licensable rights to further develop the vaccine, while A*STAR subsidiaries would earn a royalty on worldwide sales of influenza vaccine products developed under this agreement.

Frank Hennecke, PhD, Executive Vice President Product Development at Cytos Biotechnology commented: "I am very pleased we can contribute our GMP technology and process know-how in the VLP field to this collaboration. Cytos' continuing ability to supply its partners with clinical trial material is a key asset to rapidly move preclinical programs into the clinic."

"The extension of our collaboration for human proof-of-concept studies is a major step in bringing our research findings from the laboratory to the clinics where they can benefit patients. It also furthers A*STAR's close relationship with our industry partners," said Prof Alex Matter, Chief Executive Officer of A*STAR's Experimental Therapeutics Centre (ETC). Added Prof Paola Castagnoli, Scientific Director of A*STAR's Singapore Immunology Network (SIgN), "We are confident that with the combined knowledge base of Singapore's research institutes and the capabilities of industry, we will produce a valuable and cost-effective healthcare solution for Singapore and beyond."
