SAN CARLOS, Calif., Jul 24, 2006 (BUSINESS WIRE) -- Nektar Therapeutics (Nasdaq:NKTR) announced today that it has received a $17.6 million payment under a previously undisclosed license agreement with Affymax, Inc. The cash payment under the Nektar-Affymax agreement was triggered by Affymax entering into a global agreement with Takeda, Inc. to develop and commercialize Affymax's lead product candidate, Hematide(TM). Hematide utilizes Nektar Advanced PEGylation Technology and is in Phase IIb clinical trials for the treatment of anemia.
Nektar and Affymax entered into a partnership in 2004 under which Nektar provides Affymax with its Advanced PEGylation Technology to develop Hematide. Under the terms of the agreement, Nektar receives manufacturing revenue, milestone and other payments, as well as royalties on worldwide end product sales. Nektar first announced the agreement in May of 2004 as a collaboration with an undisclosed biotechnology company.
"This payment highlights the value of Nektar PEGylation technology, which is used in eight marketed products and two additional products filed for regulatory approval in the U.S. and Europe," said Rob Chess, Nektar chairman and acting chief executive officer and president. "Our PEGylation technology has proven its ability to create blockbuster drugs for our partners. As part of our focus on expanding our PEGylation business, Nektar is identifying and developing our own proprietary products using PEGylation. This includes two early-stage programs in our pipeline in the disease areas of oncology and pain."
About Nektar Advanced PEGylation Technology
Nektar Advanced PEGylation has the potential to improve the safety and efficacy of therapeutic agents by increasing drug circulation time in the bloodstream, decreasing immunogenicity and dosing frequency, increasing bioavailability and improving drug solubility and stability. It is based on the use of non-toxic polyethylene glycol (PEG) polymers, which can be attached to most major drug classes, including proteins, peptides, antibody fragments, small molecules, and other drugs and is used in eight approved products in the U.S. and/or Europe today. Two other products using Nektar Advanced PEGylation have been filed for approval by Nektar partners in both the U.S. and the European Union, including UCB's Cimzia(TM) for Crohn's Disease.
About Hematide
Hematide, a synthetic, peptide-based erythropoiesis-stimulating agent (ESA), is designed to stimulate the production of red blood cells. The product is in Phase IIb clinical trials for anemia in dialysis, pre-dialysis and cancer chemotherapy patients. ESAs address currently a $12 billion market worldwide and have been used successfully to manage anemia in patients with chronic kidney disease (CKD) and cancer-related anemia. They reduce the need for blood transfusions and the frequency and severity of anemia-associated morbidity, resulting in an improved quality of life for patients.
