What this trial is about
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.
Who can take part
Inclusion criteria
- 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
- At least one hypo- or dyskinetic segment or dilated heart chamber to demark the implant target area
- (A) Stable disease condition allowing for an elective left-lateral mini-thoracotomy (for LV applications) or (B) open-chest surgery (for RV applications) for a clinically indicated intervention on the LV (e.g., coronary bypass surgery, valve repair, mechanical circulatory support device implantation) with concomitant RV dysfunction, diagnosed using the Tricuspid Annular Plane Systolic Excursion (TAPSE) index \<16 mm (Rudski et al. 2010).
- 18-80 years of age
- Willingness and ability to give written informed consent
