NCT05566600

Brief Summary

This study is designed to evaluate the safety and efficacy of allogeneic induced pluripotent cell derived cardiomyocytes (iPSC-CMs) in treating patients with worsening ischemic heart failure undergoing coronary artery bypass graft surgery. After screening, iPSC-CMs will be administrated intramyocardially in consented and eligible patients undergoing open-chest CABG surgery and the estimated population size for the study will be 32 patients.

Outcome Measures

Primary Outcomes (1)

  • Safety in terms of the incidence and severity of adverse events

    Number of participants with death, fatal myocardial infarction, stroke, ventricular tachycardia sustained for \>15 seconds and newly formed tumor

    within 1 month post CABG surgery

Secondary Outcomes (9)

  • Incidence of adverse events

    1~6 months post CABG surgery

  • Cardiac assessment

    1~6 months post CABG surgery

  • Incidence of newly formed tumor

    1~12 months post CABG surgery

  • Immunogenic assessments

    1 month, 3 months and 6 months post CABG surgery

  • Changes in left ventricle function evaluation by echocardiogram (ECHO) or cardiac MRI

    from baseline to 12 months at 3, 6, and 12 months post CABG surgery

  • +4 more secondary outcomes
