Study Shows Otamixaban Substantially Reduced Complications of Invasive Management of Acute Coronary...(I SEPIA-ACS1/ TIMI-42 study randomized 3...),Health

Date:8/30/2009

I SEPIA-ACS1/ TIMI-42 study randomized 3241 patients from 36 countries in 6 treatment arms. The study assessed the efficacy and safety of five different doses of otamixaban versus the standard unfractionated heparin plus Glycoprotein IIb/IIIa inhibitor (eptifibatide), on background of standard dual antiplatelet therapy, in patients with high-risk non-ST-elevation acute coronary syndromes. SEPIA-ACS1 study showed that otamixaban displayed clinically meaningful activity on the primary endpoint from the threshold dose of 0.070 mg/kg/h, the second tested dose, with a consistent antithrombotic effect up to the 5th highest tested dosage. The lowest studied dosage was prematurely stopped due to insufficient activity, based on recommendation by an independent data monitoring board. Moreover a combined analysis of the intermediate doses (0.105 and 0.140 mg/kg/h) of otamixaban arms showed that otamixaban reduced by approximately 46 percent (p=0.0198) the risk of the composite of death or a second myocardial infarction, a predefined study secondary efficacy endpoint.

The potent antithrombotic effect of otamixaban was also accompanied with a dose-dependent bleeding profile. Combined intermediate otamixaban dosages showed a safety profile not statistically different with regard to TIMI major or minor bleeding through 7 days, in comparison to UFH and GPIIb/IIIa inhibitor comparator (RR 1.20, 95% CI 0.64-2.27, p=0.5634).

"The SEPIA-ACS1 trial is providing very encouraging results for a new and more effective treatment approach," said Marc Cluzel, MD Senior Vice President Research and Development Sanofi-aventis. "We aim, on the basis of these findings to address through our development program remaining patients', practionners' and payers' needs for management of ACS."

Acute Coronary Syndromes is a general term used to regroup clinical symptoms related to acute myocardial ischemia. ACS represents an area of important
