Takeda and Affymax Provide Update on Peginesatide Commercialization Rights in Japan

Takeda and Affymax Provide Update on Peginesatide Commercialization Rights in Japan

 
OSAKA, Japan & PALO ALTO, Calif.--(BUSINESS WIRE)--Takeda Pharmaceutical Company Limited (TSE:4502) and Affymax, Inc. (Nasdaq:AFFY) today announced that Takeda has decided not to commercialize peginesatide in Japan. Peginesatide is an investigational therapy for use in the treatment of patients with anemia due to chronic kidney disease (CKD). Takeda and Affymax will explore other options for the commercialization rights for this product in the Japanese market, including potentially licensing it out to a third party.

Takeda had been reviewing the business opportunity for peginesatide in Japan in view of its product portfolio and also further concentration into its core therapeutic areas and reached the conclusion that commercialization in the territory is not strategically optimal. Takeda and Affymax will continue closely collaborating in the development and commercialization of peginesatide outside Japan, including preparing for potential U.S. approval and launch and regulatory filing in Europe.

In Japan, the majority of phase 2 and phase 3 clinical trials are completed, and the findings to date suggest that peginesatide can become a promising treatment option for Japanese renal anemia patients. Accordingly, the companies are pursuing options that will take the program forward with a regulatory submission and commercialization in Japan.

Takeda and Affymax entered into two agreements signed in 2006 for development and commercialization of peginesatide, one for Japan and another for the rest of the world. In the U.S., a New Drug Application of peginesatide is under FDA review with a scheduled action date of March 27, 2012. In the European Union, Takeda expects to submit a Marketing Authorization Application during the first quarter of calendar year 2012.

About Peginesatide

 Peginesatide is a synthetic PEGylated peptidic compound that binds to and stimulates the erythropoietin receptor and thus acts as an ESA. The peginesatide Phase 3 clinical program was the largest to support the new drug application of an ESA in the treatment of anemia in CKD and the first to prospectively evaluate the cardiovascular safety of an ESA via an analysis of independently adjudicated cardiovascular events. The compound was discovered by Affymax and is being co-developed by Affymax and Takeda. If approved, peginesatide may be the first once-monthly product for anemia in CKD for dialysis patients available in the United States.
