16 Treatment Of Preserved Cardiac function heart failure with an Aldosterone anTagonist

17 New drugs

18 New drug trials Renin inhibitors (ATMOSPHERE: aliskiren vs Renin inhibitors (ATMOSPHERE: aliskiren vs enalapril vs combination)? Safe Inotropes (Istaroxime/Cardiac Myosin activator)? New vasodilators /GMPc modulators. Chimeric Natriuretic peptides. Sinus node inhibition (SHIFT: ivabradine vs placebo. NEP inhibitors(+ ARB).

19 ATMOSPHERE: design overview Aliskiren 300mg/enalapril 20 mg Daily (n=2,200) ~48 weeks (event driven) 4-8 weeks Enalapril Randomization Double-blind Primary outcome: CV death or heart failure hospitalization (event driven: 2162 patients) Enalapril +Aliskiren Open-label run-in Aliskiren 300 mg once daily (n=2,200) Enalapril 10 mg twice daily (n=2,200)

20 CK : Background Preclinical Preclinical Selective activator of cardiac myosin Selective activator of cardiac myosin Prolongs duration of systole by Prolongs duration of systole by Increasing entry rate of myosin into force- producing stateIncreasing entry rate of myosin into force- producing state Therefore overall number of active cross- bridges increasesTherefore overall number of active cross- bridges increases Increases stroke volume Increases stroke volume No change in dP/dt max No change in dP/dt max No increase in MVO 2 No increase in MVO 2

21 Istaroxime A New Calcium Cycling Modulator

22 Infusion period Post-infusion HORIZON-HF PCWP

23 Istaroxime given over a short period in patients admitted with HF and LVEF 35% receiving standard therapy: decreased PCWP and LVEDV increased CI Improved some indices of diastolic function.* No changes in neurohormones, renal function, or troponin release. In contrast to other inotropic agents available, these changes were associated with: Increase in SBP. Reduction in HR. HORIZON-HF Conclusions

24 Relaxin Mechanisms of Action Vasodilation NO, cGMP effectors Induction of NOS II/III Upregulation of endothelial endothelin type B receptor, which mediates vasodilation Preferential dilation of constricted vessels Relaxin-upregulated ET B receptors act as vasodilating ET-1 sink Anti-inflammatory Down-modulation of inflammatory cytokines linked to outcome in HF (TNF-, TGF- ) Other: Anti-ischemic, Anti-apoptotic, Anti-fibrotic Relaxin Receptor LGR7

29 ARNi Angiotensin Receptor Neprilysin inhibitor A new approach?

30 LCZ 696 Molecular complex of: An ARB - valsartan A NEP inhibitor – AHU 377

31 PARADIGM-HF A multicenter, randomized, double-blind, parallel group, active-controlled study to evaluate the efficacy and safety of LCZ696 compared to enalapril on morbidity and mortality in patients with chronic heart failure and reduced ejection fraction Primary objectives Evaluate if LCZ696 is superior in delaying time to first occurrence of either CV mortality or HF hospitalization in CHF pts (NYHA Class II – IV) with reduced ejection fraction Secondary objectives All cause mortality Renal progression (eGFR change) Clinical summary score (assessed by KCCQ) Patient population 7980 patients with CHF NYHA class II – IV and reduced ejection fraction (LVEF < 40%) BNP>150 pg/ml (NTproBNP > 600 pg/ml) or BNP > 100 pg/ml (NTproBNP > 400 pg/ml) and hospitalization within the last 12 months. LCZ mg BID (n~4000) Enalapril 10 mg BID (n~4000) Outcomes driven (estimated mean f/u = months) 1-2 weeks Enalapril 5-10 mg bid LCZ 100 mg bid LCZ 200 mg bid 1-2 weeks 2 weeks Prior ACEi/ARB use discontinued Single-blind period Double-blind period N = 7980 (1:1 randomization)

32 New trials in acute HF

33 ASCEND-HF design completed in 2010 # 7000 pts enrolled

34 2 weeks Randomization Placebo Aliskiren 300 mg Conventional therapy Aliskiren 150 mg Acute HF LVEF<40% BNP >400pg/mL SBP110mmHg ~1,800 patients Except concomitant use of an ACEI and ARB * Follow-up at Week 2, Month 1, 2 and 3, with on-going assessments every 3 months thereafter ~15 months (event-driven)* In-hospital entry and initiation Design overview Primary outcome: CV death or HF hospitalization at 6 months (381 events)
