Affymax® Reports Year End 2010 Financial Results

PALO ALTO, Calif.--(BUSINESS WIRE)-- Affymax, Inc. (Nasdaq: AFFY) today reported financial results for the year ended December 31, 2010. The net loss for the year ended December 31, 2010 was $14.1 million compared to a net loss of $76.5 million for the year ended December 31, 2009.

Affymax recognized revenue for the year ended December 31, 2010 of $112.5 million compared to $114.9 million for the year ended December 31, 2009. The decrease in revenue was the result of lower collaboration revenue from its partnership with Takeda Pharmaceutical Company Limited (Takeda), under their 2006 collaboration for development of peginesatide (previously known as Hematide™), due largely to the completion of the Phase 3 clinical trials in chronic renal failure in early 2010.

Research and development expenses for the year ended December 31, 2010 were $93.6 million compared to $157.1 million for the year ended December 31, 2009. The decrease was primarily due to a reduction in expenses associated with the Phase 3 clinical development completed in early 2010.

General and administrative expenses for the year ended December 31, 2010 were $33.3 million compared to $36.7 million for the year ended December 31, 2009 primarily due to lower legal fees in 2010.

The company had cash and investments of $118.1 million at December 31, 2010.

"Looking at planned activities in 2011, our highest priority is to submit the New Drug Application for peginesatide to the FDA in the second quarter," said John Orwin, chief executive officer at Affymax. "In addition, we will continue laying the groundwork for potential approval and launch of the product, including preparing for pre-approval inspections, getting ready for a potential FDA advisory committee review, and initiating a Phase 3b program designed to evaluate the process and outcomes of converting dialysis centers from a three times a week ESA to a once monthly ESA."

Financial Guidance

With respect to income, Affymax expects continued reimbursement from Takeda of 70 percent of third party expenses associated with research and development and 50 percent of third party expenses associated with commercial activities. Beginning mid-2011 we will also receive 50 percent reimbursement of internal expenses associated with commercial activities. Including a $10 million milestone payment the company expects to receive from Takeda in connection with the acceptance of its NDA submission by the FDA, Affymax expects to receive total payments from Takeda of $20 million to $25 million in 2011.

With respect to total operating expenses Affymax expects to incur $105 million to $110 million in operating expenses during 2011, excluding stock-based compensation. This represents a reduction from 2010 as a result of a significant reduction in Phase 3 clinical trial costs, the majority of which is offset by expenses associated with NDA preparation activities, and expansion of our commercial capabilities.

We expect cash resources, on-going Takeda reimbursement and milestone payments from Takeda to fund our operations well into 2012. Under the terms of our 2006 collaboration with Takeda, we are eligible to receive a $50 million milestone upon approval of the NDA by the FDA.
