Phase III Clinical Trial For ADENTRI(R) For Acute Decompensated Heart Failure Patients With Renal Insufficiency

�Biogen Idec (Nasdaq: BIIB) announced the initiation of a Phase III clinical trial of intravenous (IV) ADENTRI� (BG9928), an adenosine A1 sense organ antagonist, for acute decompensated heart failure (ADHF) patients with nephritic insufficiency. The trial will evaluate ADENTRI, which is being developed under a licensing agreement with CV Therapeutics (Nasdaq: CVTX), or placebo in addition to standard of care in approximately 900 patients in 21 countries globally, including the United States.


The TRIDENT-1 (TReatment with Intravenous BG9928 for patients with acutely DEcompensated heart failure and reNal insufficiency Trial) study is a Phase III randomised, multi-center, double blind, placebo-controlled, parallel-group study to assess the efficacy and safety of IV ADENTRI dosed up to five-spot days on body weight in ADHF patients with impaired nephritic function. Body weight is a bill of liquid accumulation, which is considered an important cause of symptoms experienced by pump failure patients.


"In previous clinical studies, ADENTRI has exhibited the potential to optimize runny management without harmful personal effects on renal function. Heart failure patients with renal insufficiency ar at danger for poor clinical outcomes and ar among the most difficult to handle, as presently available therapies negatively impingement renal part," said lead investigator William Abraham, M.D., Professor of Internal Medicine and Director of the Division of Cardiovascular Medicine, The Ohio State University Medical Center.

"Following lixivaptan, ADENTRI simon Marks the secondment novel compound in Biogen Idec's cardiorespiratory franchise that is in Phase III clinical trials for heart failure patients. We appear forward to advancing this and our other programs in the future."


According to the American Heart Association, spunk failure is the most common causal agent of hospitalizations in the U.S. Studies have shown that more than 60% of patients hospitalized with heart bankruptcy have renal insufficiency, which is an important sovereign determinant of survival and hospitalization in this clinical setting. The effect of renal insufficiency on sharp decompensated heart failure patients is significant as these patients tend to keep back fluid, which causes stress on both the cardiovascular and nephritic systems.
