Clinical trials

This clinical study will evaluate the safety and tolerability of HiCM-188, an investigational allogeneic induced pluripotent stem cell (iPSC)-derived cardiomyocyte therapy, in adults with advanced heart failure who are undergoing coronary artery bypass grafting (CABG) surgery. Participants who meet the study eligibility criteria will receive a single dose intramyocardial injection of HiCM-188 during CABG surgery. The study will evaluate two dose levels of HiCM-188 using an open-label dose-escalation design. Participants will be followed for up to 12 months after treatment to monitor safety and preliminary signs of clinical effect.

The purpose of this clinical study is to evaluate the efficacy and safety of intramyocardial injection of human induced pluripotent stem cell-derived cardiomyocyte injection (HiCM-188) in patients with advanced heart failure (NYHA Class III-IV)

This is an exploratory study. A total of 16 patients meeting the inclusion and exclusion criteria and awaiting coronary artery bypass grafting (CABG) surgery will be enrolled. After providing informed consent, participants will be randomized 1:1 under double-blind conditions into two groups: 1. CABG + HiCM-188-loaded chitosan patch group (patch size: 2×4 cm; containing 5 million cells per patch) 2. CABG + blank chitosan patch group (identical in appearance but without HiCM-188 cells). During CABG surgery, investigators will apply two HiCM-188-loaded chitosan patches onto the epicardial surface over regions of hypokinetic myocardium. The total transplanted cell dose per patient in the treatment group is 1 × 10⁷ . In the control group, eight patients will undergo identical surgical procedures with application of chitosan patches without HiCM-188 cells.

This clinical trial investigates the safety, feasibility, and therapeutic potential of a combined approach using HiCM-188 cardiomyocyte injection delivered intramyocardially alongside either LVAD implantation or CABG surgery in patients with advanced ischemic heart failure.
