Brief Summary

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

The purpose of this clinical study is to evaluate the feasibility, safety and efficacy of intramyocardial injection of human induce pluripotent stem cell-derived cardiomyocytes (HiCM-188) during coronary artery bypass grafting (CABG) surgery in patients with severe chronic ischemic heart failure.

Detailed Description

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

This is a single center, open-label, three-group dose-escalation (phase I) study followed by dose-extension (phase IIa) study in up to 36 severe ischemic heart failure patients. It is estimated that up to 18 phase I patients will be received HiCM-188 intramyocardial injection during CABG surgery. The maximum number of subjects after dose escalation and dose extension studies in each dose group is 12. All the subjects need take immunosuppressant after transplantation.
