Wed, 11/11/2009 - 3:26am
Sanofi-aventis and Regeneron Pharmaceuticals, Inc. have entered into agreements to expand and extend their existing global collaboration to discover, develop, and commercialize fully-human therapeutic monoclonal antibodies. Sanofi-aventis will increase its annual funding commitment from $100M to $160 million beginning in 2010, and the research funding will now extend through 2017. The companies aim to advance an average of four to five antibodies into clinical development each year. In addition to its VelocImmune® technology, Regeneron will contribute to the collaboration its next generation technologies related to antibody generation. Sanofi-aventis has an option to extend the discovery program for up to an additional three years for further antibody development and preclinical activities. The amendments announced today do not change the financial terms of the November 2007 agreement governing the development and commercialization of antibody drug candidates arising from the discovery collaboration. "The first two years of our collaboration with sanofi-aventis have been extremely productive, with five VelocImmune® human antibodies in or entering clinical development," commented Leonard S. Schleifer, M.D., Ph.D., President and Chief Executive Officer of Regeneron. "The expansion of our collaboration provides even greater resources over a longer time horizon and will boost our efforts to build a deep pipeline of new human antibody product candidates. Sanofi-aventis is an ideal partner with the expertise and global reach to collaborate with us on our mission to bring important new medicines to patients around the world." "This collaboration expansion demonstrates sanofi-aventis' commitment to become a key player in the field of monoclonal antibodies and our confidence in our partner Regeneron," declared Marc Cluzel, Executive Vice President, R&D, sanofi-aventis. "It will further fuel our product pipeline and will allow us to bring multiple antibody product candidates into the clinic, thereby significantly increasing the chance of providing patients access to innovative drugs in various therapeutic areas." To date, Regeneron and sanofi-aventis have advanced four therapeutic antibodies into clinical development and have filed an IND for a fifth additional antibody. Among the four antibodies in clinical development, three are antibodies to (1) the Interleukin-6 receptor (IL-6R), being developed for the treatment of rheumatoid arthritis, (2) Nerve Growth Factor, being developed for the treatment of pain, and (3) Delta-like Ligand 4 (Dll4), being developed for the treatment of advanced malignancies. The targets of the two other antibodies have not been disclosed.
