Brief Summary

This study aims to evaluate the safety and efficacy of fibroblast activation protein (FAP)-targeted autologous immunosuppressive chimeric antigen receptor dendritic cell (iCDC) therapy in patients with ischemic cardiomyopathy, and to explore its potential as a novel therapeutic strategy for this disease.

Conditions

Keywords

Outcome Measures

Primary Outcomes (2)

• Incidence of Dose-Limiting Toxicities (DLT)

  Incidence of dose-limiting toxicities (DLT) within 14 days after administration of FAP-targeted immunoregulatory CAR-DC therapy

  Within 14 days after treatment

• Incidence of Treatment-Emergent Adverse Events (TEAE)

  Incidence of treatment-emergent adverse events (TEAE) occurring within 6 months after treatment in patients with ischemic cardiomyopathy.

  Within 6 months after treatment

Secondary Outcomes (20)

• Change in Left Ventricular Ejection Fraction (LVEF) by Echocardiography

  Baseline, 3 months, 6 months

• Change in left ventricular end-systolic volume (LVESV) as assessed by Echocardiography

  Baseline, 3 months, and 6 months

• Change in left ventricular end-diastolic volume (LVEDV) by Echocardiography

  Baseline, 3 months, and 6 months

• Change in global longitudinal strain (GLS) measured by Echocardiography

  Baseline, 3 months, 6 months

• Change in wall motion score index (WMSI) measured by Echocardiography

  Baseline, 3 months, 6 months

Study Arms (2)

Administration of autologus FAP iCDC

EXPERIMENTAL

Administration of FAP immunosuppressive CAR-DC cell therapy in ischemic cardiomyopathy. Patients are planned to be enrolled in the dose-escalation trial (1×10\^5/kg、4×10\^5/kg、and 8×10\^5/kg) .The first dose group (4×10⁵/kg) initially enrolls 3 subjects to observe Dose-Limiting Toxicity (DLT) responses. （1）If no DLT occurs and all 3 subjects demonstrate efficacy after 6 months of treatment, and this dose is determined as the safe and effective dose. （2）If 1 subject experiences DLT, 3 additional subjects are enrolled. ·If 1/6 subjects develops DLT, and efficacy is not fully achieved in all 6 subjects, escalate to the next dose group (8×10\^5/kg). ·If ≥2/6 subjects develop DLT, de-escalate to the previous dose group (1×10\^5/kg). （3）After identifying a safe and effective dose, enrollment will be expanded at this dose to bring the total sample size to 15 subjects, to further evaluate safety and efficacy.

Biological: autologus FAP-targeted immunosuppressive CAR-DCs (iCDC)

Standard treatment control

ACTIVE COMPARATOR

Participants in this arm will receive standard medical treatment for ischemic cardiomyopathy according to current clinical practice and guideline-directed medical therapy. These participants will not receive iCDC therapy but will undergo scheduled follow-up assessments for safety and efficacy comparisons.

Other: Standard medical treatment

Interventions

autologus FAP-targeted immunosuppressive CAR-DCs (iCDC) BIOLOGICAL

Each subject receives FAP-targeted immunosuppressive CAR-DCs by intravenous infusion after enrollment.

Administration of autologus FAP iCDC

Standard medical treatment OTHER

Participants receive standard medical treatment for ischemic cardiomyopathy according to current clinical practice and guideline-directed medical therapy. No iCDC therapy is administered in this arm.
