Engineered immune cells aim to repair damaged hearts

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Age ≥18 years and ≤75 years. * Diagnosis of ischemic cardiomyopathy, with at least 3 months of optimized guideline-directed medical therapy (GDMT) at maximally tolerated doses; left ventricular ejection fraction (LVEF) \<35%; New York Heart Association (NYHA) functional class III-IV. * Ability to understand the risks, benefits, and treatment alternatives of immunoregulatory CAR-DC therapy, and willingness to participate in the study; the patient or his/her legally authorized representative must provide written informed consent prior to study enrollment. * Adequate hematologic function defined as: hematocrit \>30%, lymphocyte count \>0.5 × 10⁹/L, and platelet count \>60 × 10⁹/L. Exclusion Criteria: * Life expectancy \<1 year due to non-cardiac conditions. Cardiac resynchronization therapy (CRT) implantation within 3 months prior to enrollment or planned CRT implantation. Percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) within 3 months prior to enrollment OR plan to PCI. Presence of non-ischemic cardiomyopathy, including but not limited to dilated cardiomyopathy, hypertrophic cardiomyopathy, restrictive cardiomyopathy, arrhythmogenic cardiomyopathy, peripartum cardiomyopathy, inflammatory or immune-mediated cardiomyopathy, metabolic or genetic cardiomyopathy, or cardiomyopathy secondary to moderate-to-severe valvular heart disease, congenital heart disease, or other non-ischemic etiologies. Persistent hemodynamic instability. End-stage renal disease (eGFR \<25 mL/min/1.73 m²) requiring or receiving renal replacement therapy (hemodialysis or peritoneal dialysis). Active autoimmune disease requiring immunosuppressive therapy. History of malignancy. Active infection, including but not limited to active hepatitis B (HBV DNA \>1000 copies/mL by PCR), hepatitis C, syphilis, or human immunodeficiency virus (HIV) infection, or uncontrolled systemic fungal, bacterial, viral, or other infections. Pregnant women. Known contraindications to the investigational product or study-related procedures.
