Amylin and Lilly End Diabetes Partnership

Amylin Pharmaceuticals and Eli Lilly and Company have agreed to terminate their alliance for type 2 diabetes drug, BYETTA (exenatide), and resolve the outstanding litigation between the companies. As part of the agreement, Amylin will take full responsibility for the worldwide development and commercialization of exenatide, starting in the United States (U.S.) on November 30, 2011, and progressing to all markets by the end of 2013. 
After nearly a decade-long partnership that achieved a number of important milestones on behalf of people living with diabetes, the companies determined it was in the best interest of all constituents to amicably terminate the collaboration. Both companies are committed to ensuring a seamless transition of global product responsibility to Amylin while maintaining continuity of patient care. 
Under the terms of the new global agreement, Amylin will make a one-time, upfront payment to Lilly of $250 million. Amylin will also agree to make future revenue sharing payments to Lilly in an amount equal to 15 percent of global net sales of exenatide products until Amylin has made aggregate payments to Lilly of $1.2 billion plus accrued interest. Amylin will issue a secured note in the amount of $1.2 billion to Lilly under which any revenue sharing payments made to Lilly will reduce amounts outstanding under the note. If Amylin’s investigational once weekly version of exenatide, BYDUREON (exenatide extended-release for injectable suspension), has not received U.S. Food and Drug Administration (FDA) approval prior to June 30, 2014, Amylin’s revenue sharing obligations will terminate, and Amylin shall thereafter pay Lilly 8 percent of global net sales of exenatide products. Amylin will also pay a $150 million milestone to Lilly contingent upon FDA approval of a once monthly suspension version of exenatide that is currently in Phase 2. The companies have also agreed that the maturity date for the $165 million line of credit that Amylin drew from Lilly earlier in the year will be extended from the second quarter of 2014 to the second quarter of 2016. 
The transition of commercial operations to Amylin in the U.S. will be complete by November 30, 2011. Outside the U.S., Lilly will transfer responsibility for commercialization of BYETTA (exenatide) injection and BYDUREON to Amylin on a market-by-market basis in 2012 and 2013. Amylin will work with Lilly on all plans for markets outside the U.S. during the transition period and will guarantee that Lilly does not experience losses on exenatide-related activities during that period, up to a total cap of $60 million. 
The Amylin and Lilly alliance resulted in several innovations in the diabetes market. These innovations include the 2005 launch of the first-in-class GLP-1 receptor agonist, BYETTA, a treatment that has been used by 1.8 million patients worldwide, and submission of the first once-weekly GLP-1 receptor agonist, BYDUREON, an investigational medication for type 2 diabetes designed to deliver continuous therapeutic levels of exenatide in a single weekly dose. BYDUREON received marketing authorization in the European Union in June 2011 and is currently under review in the U.S., with a Prescription Drug User Fee Action (PDUFA) date of January 28, 2012. Amylin will continue to evolve the GLP-1 market with the exenatide franchise through the development of a pen device for BYDUREON and the exenatide monthly suspension program.

This is really not surprising since Lilly signed a partnership deal with Boehringer Ingelheim to market a product that competes directly with Amylin’s GLP agonist known as Byetta for type 2 diabetes.  While Lilly rationalized the deal payers are more attracted to companies offering an entire range products which Lilly did not have, but as one might imagine, Amylin saw the deal as a violation of their partnership agreement, and the company sued.  This ends a partnership, now the only question is whether Amylin can survive as a stand-alone player, or whether it will be acquisition bait for a company like Sanofi?  Much will… Read more »
