SURVIVE-W Survival of Patients with Acute Heart Failure in Need of Intravenous Inotropic Support Presented at The American Heart Association Scientific Sessions, November 2005 Presented by Dr. Alexandre Mebazaa SURVIVE-W: Background • Levosimendan, a calcium-sensitizing agent that has both vasodilator and inotropic effects, has been proposed as an alternative to the standard treatment of dobutamine • Two small pilot trials, LIDO and CASINO, showed lower rates of mortality with levosimendan compared with dobutamine and placebo • The goal of the trial is to compare treatment with levosimendan to treatment with dobutamine in patients with acute heart failure who are in need of intravenous inotropic support • SURVIVE is the first prospective randomized mortality trial of IV drug therapy in acute decompensated heart failure www. Clinical trial results.org SURVIVE-W: Design 1327 patients with acute decompensated heart failure, left ventricular ejection fraction ≤ 30%, clinical need for inotropic therapy after intravenous diuretics and/or vasodilators Levosimendan Dobutamine (12 µg/kg bolus plus 0.1-0.2 µg/kg/min infusion for 24 hours) (≥5 µg/kg/min infusion for ≥ 24 hours) n=663 n=664 Endpoints: Primary – All cause mortality at 6 months Secondary – All-cause mortality at 31 days, BNP at 24 hours, days alive out of hospital, change in patient dyspnea assessment, change in patient global assessment www. Clinical trial results.org SURVIVE-W: Primary endpoint 35% All-Cause Mortality at 6 months (% of treatment arm) p = 0.401 30% 27.9% 26.1% 25% 20% 15% 10% • There was no significant difference in the primary endpoint of all-cause mortality between the levosimendan and dobutamine groups 5% 0% Levosimendan www.

Clinical trial results.org Dobutamine ESC 2005 SURVIVE-W: Post-hoc Analysis 8% All-cause mortality at 5 days (% of treatment arm) p = NS 6.0% 6% 4.4% 4% 2% In a post-hoc analysis, allcause mortality at 5 days was not significantly different between treatment groups 0% Levosimendan www. Clinical trial results.org Dobutamine ESC 2005 SURVIVE-W: Limitations • REVIVE-2, the complement trial to SURVIVE, compared levosimendan against placebo and showed no mortality benefit. Thus, although levosimendan is not associated with increased mortality compared to dobutamine, it does not improve mortality compared to placebo. • There was a significant reduction in BNP in the levosimendan group compared to the dobutamine group. While BNP is a marker, this study raises questions as to whether BNP is a surrogate endpoint given that the treatment was not associated with reduced mortality. www. Clinical trial results.org SURVIVE-W: Summary • Among patients with acute heart failure in need of intravenous inotropic support, treatment with levosimendan did not significantly reduce all-cause mortality compared with treatment with dobutamine • There was no difference in all-cause mortality at 31 days or at 5 days though in the subgroup of patients with a history of heart failure, mortality did trend lower at 5 days • BNP at 24 hours was significantly lower (p=<0.001) in the levosimendan group compared with the dobutamine group. BNP dropped by almost 50% after the infusion and stayed low for at least five days • There were no differences in hypotension or ventricular tachycardia. However, atrial fibrillation occurred more often in the levosimendan group (9% vs 6%) while cardiac failure occurred less often in the levosimendan group (12% vs 17%) www.
