Ranexa(R) Significantly Reduces Incidence of CV Death, MI or Recurrent Ischemia in MERLIN TIMI-36 Patients With Elevated BNPORLANDO, Fla., Nov. 5 (HSMN NewsFeed) -- CV Therapeutics, Inc. (Nasdaq: CVTX ) announced today that RanexaŽ (ranolazine extended-release tablets) reduced the relative risk of the primary composite endpoint of CV death, myocardial infarction or recurrent ischemia by 21 percent compared to placebo in 1,935 patients with an elevated (>80pg/ml) level of b-type natriuretic peptide (BNP) in the MERLIN TIMI-36 study (p=0.009).
The data were presented today by Dr. David Morrow of the TIMI Study Group at the American Heart Association Scientific Sessions in Orlando, Florida.
Ranolazine is believed to exert its anti-ischemic effects through ion channel activity which may ultimately reduce left ventricular (LV) wall stress and improve diastolic dysfunction. BNP rises in response to LV wall stress and is a potent indicator of risk in acute coronary syndromes (ACS).
"The potential enhanced efficacy of ranolazine in patients with elevated BNP in this analysis is consistent with the drug's mechanism of action. Elevated BNP is among the most powerful indicators of risk for ACS patients, and it is very intriguing to see the potentially beneficial effects of ranolazine in this group of MERLIN TIMI-36 patients," Morrow said. "Few interventions have been shown to modify the risk associated with increased BNP. This finding warrants prospective confirmation," he added.
In accordance with a special protocol assessment agreement between the U.S. Food and Drug Administration (FDA) and CV Therapeutics, the Company believes that data from the MERLIN TIMI-36 study could support expansion of the existing Ranexa indication to first line angina. In September 2007, the Company submitted a supplemental new drug application to the FDA seeking a new indication for first line angina and a significant reduction in cautionary language.
Ranexa is currently indicated for the treatment of chronic angina in patients who have not achieved an adequate response with other antianginal drugs, and should be used in combination with amlodipine, beta-blockers or nitrates.
MERLIN TIMI-36 (Metabolic Efficiency with Ranolazine for Less Ischemia in Non-ST Elevation Acute Coronary Syndromes) was a multi-national, double-blind, randomized, placebo-controlled, parallel-group clinical trial designed to evaluate the efficacy and safety of Ranexa during acute and long-term treatment in 6,560 patients (3,279 received ranolazine, 3,281 received placebo) with non-ST elevation ACS treated with standard therapy.
Within 48 hours of the onset of angina due to ACS, eligible hospitalized patients were enrolled in the study and randomized to receive intravenous Ranexa or placebo, followed by long-term outpatient treatment with Ranexa extended-release tablets or placebo. All patients also received standard therapy during both hospital-based and outpatient treatment. The doses of Ranexa extended-release tablets used in MERLIN TIMI-36 have been studied in previous Phase 3 clinical trials.
Participants in the MERLIN TIMI-36 study received current standard therapy, with approximately 96 percent of patients on aspirin, approximately 89 percent on beta blockers and approximately 82 percent on statins. Approximately 59 percent of study participants received coronary angiography during their initial hospitalization.
Previously published data from the MERLIN TIMI-36 study has shown that Ranexa was safe in this population of patients with coronary artery disease, which included nearly 1,100 patients with prior heart failure.
