Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Heart failure has a high morbidity and mortality because the heart is one of the least regenerative organs in the human body. Drug treatments for heart failure manage symptoms but do not restore lost myocytes. Cellular replacement therapy is a potential approach to repair damaged myocardial tissue, restore cardiac function, which has become a new strategy for the treatment of heart failure. The purpose of this study is to assess the safety and efficacy of intramyocardial delivery of cardiomyocytes at the time of coronary artery bypass grafting in patients with chronic heart failure.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients with heart failure will be treated with allogenic human pluripotent stem cell-derived cardiomyocytes ( hPSC-CM ) from healthy donors. The cells will be injected directly into the myocardium at time of coronary artery bypass grafting. Patients will be assessed at 1, 3, 6 and 12 months after cell transplantation for safety and efficacy.
