Exelixis Licenses Programs to Bristol-Myers Squibb Company
-Exelixis To Receive Initial Payment of $60 Million-
 

SOUTH SAN FRANCISCO, Calif., Oct 11, 2010 (BUSINESS WIRE) -- Exelixis, Inc. /quotes/comstock/15*!exel/quotes/nls/exel (EXEL 4.47, +0.24, +5.67%) announced today that it has entered into two new collaboration agreements with Bristol-Myers Squibb Company /quotes/comstock/13*!bmy/quotes/nls/bmy (BMY 27.36, +0.20, +0.72%) . Under the first agreement, Exelixis will grant to Bristol-Myers Squibb an exclusive license to its small-molecule TGR5 agonist program including backups. Under the second agreement, the companies will collaborate to discover, optimize, and characterize small-molecule ROR antagonists. The companies have also made minor amendments to their XL281 and liver X receptor (LXR) agreements. Finally, under the companies' cancer collaboration agreement Exelixis has opted to exercise its right to opt out of further co-development of XL139 and will receive an accelerated milestone payment.

Under the terms of the new agreements, Bristol-Myers Squibb will make a combined initial payment of $60 million to Exelixis. Exelixis will be eligible for potential development and approval milestone payments of up to $250 million on TGR5 and $255 million on the ROR antagonists. Exelixis will also be eligible for combined sales performance milestones, and royalties on net sales of products from each of the TGR5 and ROR programs. Bristol-Myers Squibb will receive an exclusive worldwide license to develop and commercialize small molecule TGR5 agonists and ROR antagonists. Under the TGR5 agreement, Bristol-Myers Squibb will have sole responsibility for research, development, manufacturing, and commercialization. Under the ROR agreement, Bristol-Myers Squibb and Exelixis will collaborate on ROR antagonist programs up to a pre-clinical transition point and then Bristol-Myers Squibb will have sole responsibility for the further research, development, manufacture, and commercialization.

Exelixis is granting rights to the ROR program in exchange for Bristol-Myers Squibb waiving rights to receive a third Investigational New Drug (IND) candidate as agreed to under a collaboration signed in 2006 between the two companies in the area of oncology.

After Exelixis opts-out of further co-development of XL139, Bristol-Myers Squibb will receive an exclusive worldwide license to develop and commercialize, and will have sole responsibility for the further development, manufacture, and commercialization of the compound.

"We continue our strong relationship with Bristol-Myers Squibb and are excited for these collaborations to maximize the potential of these novel programs and bring benefits to patients with serious diseases," said Michael M. Morrissey, Ph.D., president and chief executive officer of Exelixis. "These transactions leverage our discovery expertise with the development expertise of Bristol-Myers Squibb in inflammation and metabolic diseases, and provide important additional resources for us to continue our focus on our clinical stage development pipeline."

TGR5 is a G-protein coupled bile acid receptor (GPCR) which is highly expressed in the gall bladder and intestine. Through TGR5, bile acids promote the secretion of glucogen-like peptide-1 (GLP-1), a hormone that affects multiple metabolic parameters including increased insulin secretion from the pancreas and lowering of blood glucose. Stimulating GLP-1 secretion by activation of TGR5 has the potential to be complementary to the use of dipeptidyl peptidase-4 (DPP-IV) inhibitors for the treatment of diabetes.

ROR is a member of the nuclear hormone receptor family that is expressed in multiple cell types including T-cells. ROR plays a prominent role in the development and activity of the TH17 subset of T-cells, which secrete IL-17 and are associated with a variety of inflammatory disorders. Small molecule antagonists of ROR inhibit production of these pro-inflammatory cytokines and have broad potential as novel anti-inflammatory compounds.

The TGR5 license agreement and the amendment to the cancer collaboration agreement signed in 2006 are subject to antitrust clearance under the Hart-Scott-Rodino Antitrust Improvements Act and other customary regulatory approvals.
