Brief Summary

It is believed that targeted SERCA2a enzyme replacement in HFrEF patients will correct defective intracellular Ca2+ hemostasis, resulting in improved cardiac contractile function and energetics which will, in turn, translate to improved clinical outcomes. Additionally, it is hypothesized that correcting SERCA2a dysfunction will also improve coronary blood flow through correction of the impaired endothelium-dependent nitric oxide-mediated vasodilatation observed in heart failure.

Eligibility Criteria

Main Inclusion Criteria: * Chronic ischemic or non-ischemic cardiomyopathy * NYHA class III/IV * LVEF ≤35% * Guideline-directed medical therapy for heart failure; ICD Main Exclusion Criteria: * Restrictive cardiomyopathy, hypertrophic cardiomyopathy, acute myocarditis, pericardial disease, amyloidosis, infiltrative cardiomyopathy, uncorrected thyroid disease or discrete left ventricular (LV) aneurysm * Prior heart transplantation, left ventricular reduction surgery (LVRS), cardiomyoplasty, passive restraint device (e.g., CorCap™ Cardiac Support Device), mechanical circulatory support device (MCSD) or cardiac shunt * Likely to receive cardiac resynchronization therapy, cardiomyoplasty, LVRS, conventional revascularization procedure or valvular repair in the 6 months following treatment * Likely need for an immediate heart transplant or MCSD implant due to hemodynamic instability * Inadequate hepatic and renal function * Diagnosis of, or treatment for, any cancer within the last 5 years except for basal cell carcinoma or carcinomas in situ where surgical excision was considered curative
