This study will follow principles of the previously described mechanistic translational-phase concept whereby the effect of the study agent on laboratory and imaging markers of cardiac structure and function will be tested in a small homogenous cohort with the goal to enhance the understanding of the effect of interventions on cardiac remodeling and performance.Abstract: STUDY DESIGN: This single-blind, placebo-controlled, crossover, multicenter, randomized study will assess the safety, tolerability, and preliminary efficacy of a single intravenous (i.v.) dose of allogeneic ischemia-tolerant MSCs in individuals with heart failure of nonischemic cause, ejection fraction 40% or less, and dysfunctional viable myocardium who have been receiving guideline-directed medical therapy. Eligible patients will have no evidence of baseline replacement scarring on delayed-enhancement cardiac magnetic resonance (CMR). Approximately 20 patients will be randomized in a 1 : 1 ratio to receive an i.v. infusion of ischemia-tolerant MSCs or placebo. At 90 days, the two groups will undergo crossover and received the alternative treatment. The primary endpoint is safety, as evaluated through at least 1-year post-MSC infusion. Additional efficacy endpoints will include measures of cardiac structure and function, as evaluated by serial cine-CMR and transthoracic echocardiography at 90 and 180 days post-initial infusion.Abstract: CONCLUSION: This pilot study will explore the safety and effects on cardiac structure and function of i.v. injection of ischemia-tolerant MSCs in a small homogenous cohort of nonischemic heart failure patients with reduced ejection fraction and absent replacement scarring on CMR. This study also represents a prospective mechanistic translational-phase study using baseline and serial CMR imaging in heart failure patients and serves as a potential model for design of future heart failure trials ( identifier: NCT02467387).
