HiCM-188 Cell Therapy in Adults With Advanced Heart Failure Undergoing Heart Bypass Surgery
A Phase I/IIa, Open-Label, Dose Escalation Study to Evaluate the Safety and Tolerability of HiCM-188, an Allogeneic iPSC-derived Cardiomyocyte Therapy, in Adult Patients With Advanced Heart Failure
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.

Descrizione dettagliata
This is a Phase I/IIa, open-label, dose-escalation study of HiCM-188 in adult participants with advanced heart failure. HiCM-188 is an investigational cell therapy product consisting of allogeneic human iPSC-derived cardiomyocytes intended for intramyocardial administration.
Eligible participants will receive HiCM-188 during coronary artery bypass grafting (CABG) surgery. The study uses a 3+3 dose-escalation design to evaluate two dose levels of HiCM-188: 0.5 × 10^8 cells and 1.5 × 10^8 cells. The primary objective is to evaluate the safety and tolerability of intramyocardial injection of HiCM-188. Secondary objectives include evaluation of preliminary efficacy based on cardiac function, myocardial perfusion, exercise capacity, NYHA functional classification, quality of life, and major adverse cardiac events.
Participants will be monitored during the in-hospital period after CABG surgery and HiCM-188 administration, and then followed for up to 12 months after treatment.
