The BioVAT-HF trial will test the hypothesis that cardiomyocyte implantation via engineered heart muscle (EHM), the proposed investigational medicinal product (IMP; designated "Biological Ventricular Assist Tissue" or BioVAT), results in sustainable remuscularization and biological enhancement of myocardial performance in the failing heart. EHM are constructed from defined mixtures of induced pluripotent stem cell (iPSC)-derived cardiomyocytes and stromal cells in a bovine collagen type I hydrogel. Comprehensive preclinical testing confirmed the rationale for the clinical translation of the myocardial remuscularization strategy by EHM implantation. The patient target population for EHM therapy is patients suffering from advanced heart failure with reduced ejection fraction (HFrEF; EF: ≤35%) and no realistic option for heart transplantation.
Symptomatic heart failure (NYHA II-IV) with reduced ejection fraction (HFrEF with LVEF ≤35%) as assessed by echocardiography.
Patients on guideline-directed medical therapy
NT-proBNP >300 pg/mL for patients in sinus rhythm or >900 pg/mL if in atrial fibrillation
History of previous heart failure hospitalization in the past 12 months
Contraindication to immunosuppressive drugs (e.g. known history of unresolved cancer, hepatitis B/C, HIV, HTLV1)
Contraindication to TachoSil® (e.g. hypersensitivity to human fibrinogen, human thrombin, horse collagen, human albumin, Riboflavin, Natriumchloride, Natriumcitrate, L-Arginin-Hydrochloride)
Hypertrophic cardiomyopathy (HCM)
Terminal kidney failure (stage 4; GFR <30 ml/min) at the time of enrolment
