FIVEPRIME AND PFIZER ENTER ONCOLOGY AND DIABETES COLLABORATION
SAN FRANCISCO, California – May 20, 2008. Five Prime Therapeutics, Inc. and Pfizer Inc. (NYSE:PFE) today announced the initiation of a worldwide collaborative research and license agreement. The collaboration will focus on the discovery of antibody targets and novel therapeutic protein products to treat certain areas of cancer and diabetes. Under the collaboration, FivePrime will screen its comprehensive protein library in both cell-based assays and primary in vivo screens directed toward finding potential therapeutic protein products and antibody targets.
Upon the commencement of the collaboration, FivePrime will receive an up-front payment and
an equity investment from Pfizer and three years of committed research funding. Pfizer will
have exclusive worldwide rights to develop and commercialize certain products and targets
discovered during the research term, in exchange for future milestones and royalties. Further
details of the agreement have not been disclosed.
“Pfizer’s commitment to biotherapeutics and its extensive development and commercialization
capabilities are an ideal match for FivePrime’s powerful biologics discovery platform. This
combination will increase the likelihood and speed of discovering and developing new
biotherapeutics for patients in need” stated Lewis T. (“Rusty”) Williams, MD, PhD, FivePrime’s
Founder and Executive Chairman.
FivePrime’s existing investors made a co-investment in FivePrime in conjunction with Pfizer’s
equity purchase. “This is a very significant transaction for FivePrime,” commented Gail Maderis,
President and CEO of FivePrime. “It provides the financial runway to take several of our
oncology products into clinical trials in addition to greatly expanding our discovery efforts.”
A key component of the collaboration is FivePrime’s comprehensive, rapid protein discovery
system. Its protein screening library contains essentially all human secreted proteins and their
receptors, including many that are unavailable in public collections. FivePrime screens its
protein library in both complex, primary cell assays and in high-throughput in vivo systems. The
in vivo technology is also used for rapid validation of hits, significantly reducing the time from an
idea to an Investigational New Drug.
“We are very excited about this research collaboration, as it will fill a core need for Pfizer’s new
biologics enterprise, the Biotherapeutics and Bioinnovation Center (BBC),” said BBC President
Corey Goodman, PhD. “Our mission is to gain access to the best internal and external science
and to achieve Pfizer’s corporate ambition of becoming a global leader in biotherapeutics. The
investment and partnership with FivePrime represents a key milestone in our efforts as we are
confident it will generate therapeutic proteins and antibodies that will ultimately lead to
innovative medicines for patients worldwide.”
