Amgen Announces Top-Line Results of Trial to Reduce Cardiovascular Events With Aranesp(R) Therapy (TREAT) in CKD Patients With Type-...( THOUSAND OAKS Calif...),Health

THOUSAND OAKS, Calif., Aug. 25 /PRNewswire-FirstCall/ -- Amgen (Nasdaq: AMGN) today announced that in a large, randomized, double-blind, placebo-controlled, Phase 3 study of patients with chronic kidney disease (CKD) (not requiring dialysis), anemia and type-2 diabetes (the Trial to Reduce Cardiovascular Endpoints with Aranesp((R)) Therapy, or TREAT), treatment of anemia with Aranesp((R) )(darbepoetin alfa) to a hemoglobin target of 13 g/dL had no statistically significant effect on either of two primary endpoints compared with placebo treatment. The two primary endpoints were a composite of time to all-cause mortality or cardiovascular morbidity (including heart failure, heart attack, stroke, or hospitalization for myocardial ischemia) and a composite of time to all-cause mortality or chronic renal replacement therapy. Among the elements that formed these composite endpoints, an excess of stroke events (a labeled risk of Aranesp therapy) occurred in the Aranesp-treated patients compared to those receiving placebo.

These summary results will be followed by full efficacy and safety analyses, which will be shared with global regulatory authorities and presented at an upcoming medical meeting later this year.

"TREAT was designed to answer important questions about the effects of erythropoiesis-stimulating agents (ESAs) on cardiovascular and renal outcomes in patients with renal insufficiency and type-2 diabetes. It is by any measure the most comprehensive analysis that has ever been performed to examine the impact of anemia therapy in patients who do not yet require dialysis. The trial will provide nephrologists with important information as they endeavor to improve renal care," said Roger M. Perlmutter, M.D., Ph.D., executive vice p
