Takeda Pharmaceuticals U.S.A. (TPUSA) and Affymax, Inc. (Nasdaq:AFFY) today announced that Takeda Pharmaceuticals America, Inc. (TPA) has entered into a supply agreement for sourcing and supply of OMONTYS ®(peginesatide) Injection with U.S. Renal Care, Inc. and certain of its affiliates, representing one of the top 10 dialysis providers in the United States (U.S.). OMONTYS is the only once-monthly erythropoiesis-stimulating agent (ESA) for anemia available to the dialysis patient population with chronic kidney disease (CKD) in the U.S. The agreement allows U.S. Renal Care to purchase OMONTYS for use within its organization and provides for discounts and rebates on the product, subject to certain requirements. U.S. Renal Care has indicated that they plan to initially evaluate OMONTYS in selected centers, and then, based on experience, evaluate the potential to expand to additional centers. Financial terms were not disclosed. “As we anticipated, there is interest from some of the world’s leading dialysis providers to offer a new therapeutic option for the treatment of anemia in chronic kidney disease patients on dialysis,” said Nicole Mowad-Nassar, vice president, marketing at Takeda. “These centers are demonstrating an interest in offering new therapies and showing their commitment to innovation,” stated John Orwin, chief executive officer of Affymax. “We intend to support their integration efforts and believe OMONTYS will prove to be a once-monthly alternative in their centers moving forward.” OMONTYS was approved by the FDA on March 27, 2012, for the treatment of anemia due to CKD in adult patients on dialysis. OMONTYS is not indicated, and is not recommended, for use in patients with CKD not on dialysis, in patients receiving treatment for cancer and whose anemia is not due to CKD, or as a substitute for red blood cell (RBC) transfusions in patients who require immediate correction of anemia. OMONTYS has not been shown to improve symptoms, physical functioning, or health-related quality of life. Please see Important Safety Information including Boxed WARNINGS below. About OMONTYS OMONTYS ® (peginesatide) Injection is a synthetic, pegylated, peptide-based ESA. It is the only ESA that is peptide-based and its building blocks (amino acids) are arranged in a different order than erythropoietin (i.e., it has no sequence homology to endogenous erythropoietin). On March 27, 2012, the United States Food and Drug Administration approved OMONTYS for the treatment of anemia due to CKD in adult patients on dialysis. OMONTYS is the only once-monthly erythropoiesis-stimulating agent (ESA) for anemia available to this patient population in the United States.
