Amgen in Discussions with FDA to Update U.S. Prescribing Information for ESAs

Revised ESA Labeling to be Based on New Data from PREPARE and GOG Studies

THOUSAND OAKS, Calif.--(BUSINESS WIRE)--Dec. 6, 2007--Amgen Inc. (NASDAQ:AMGN) today announced the company is in discussions with the U.S. Food and Drug Administration (FDA) with the goal of updating safety information in all erythropoiesis-stimulating agents (ESAs) labeling based on safety data from the recently announced PREPARE interim study results in neoadjuvant breast cancer and the recently published follow up data from the Gynecologic Oncology Group (GOG) study in cervical cancer. While Amgen's interactions with the FDA are ongoing and exact language for the updated labeling is not final, the company is committed to providing timely and appropriate communications to patients and physicians.

Amgen and the FDA are discussing the label changes under the regulatory mechanism known as a "changes being effected" (CBE) process. Additionally, Amgen has been advised there will be an Oncologic Drugs Advisory Committee (ODAC) meeting in the first quarter of 2008 as part of the ongoing pharmacovigilance review of ESA therapies. Decisions around the precise timing of this ODAC meeting will not be finalized until publication by the FDA in the Federal Register.

"The PREPARE and GOG studies were off-label, high-hemoglobin target studies that contain important information relevant to specific patient populations receiving ESAs," said Roger M. Perlmutter, M.D., Ph.D., executive vice president of Research and Development at Amgen. "As new information, including additional study results, becomes available, Amgen will communicate the data and, where appropriate, work with the FDA to update our product labels."

Additional information about the PREPARE and GOG studies is available at

About Aranesp

Aranesp was approved by the FDA in September 2001 for the treatment of anemia associated with chronic renal failure (CRF) for patients on dialysis and patients not on dialysis. In July 2002, the FDA approved weekly dosing of Aranesp for the treatment of anemia caused by concomitantly administered chemotherapy in patients with nonmyeloid malignancies and in March 2006, the FDA approved every-three-week dosing in these patients.

Important Aranesp Safety Information


Renal failure: Patients experienced greater risks for death and serious cardiovascular events when administered erythropoiesis- stimulating agents (ESAs) to target higher versus lower hemoglobin levels (13.5 vs. 11.3 g/dL; 14 vs. 10 g/dL) in two clinical studies. Individualize dosing to achieve and maintain hemoglobin levels within the range of 10 to 12 g/dL.


-- ESAs shortened overall survival and/or time-to-tumor progression in clinical studies in patients with advanced breast, head and neck, lymphoid, and non-small cell lung malignancies when dosed to target a hemoglobin of greater than or equal to 12 g/dL.
-- The risks of shortened survival and tumor progression have not been excluded when ESAs are dosed to target a hemoglobin of less than 12 g/dL.
-- To minimize these risks, as well as the risk of serious cardio- and thrombovascular events, use the lowest dose needed to avoid red blood cell transfusions.
-- Use only for treatment of anemia due to concomitant myelosuppressive chemotherapy.
-- Discontinue following the completion of a chemotherapy course.

Aranesp is contraindicated in patients with uncontrolled hypertension.
