TrueCardium® is a patented human cardiac organoid platform that recreates key structural and functional properties of human heart tissue in vitro, enabling highly predictive assessment of cardiac safety, disease biology, and therapeutic response.
TrueCardium® is the only human cardiac organoid system that is vascularised, innervated, and incorporates mural, stromal and resident immune cell populations, enabling integrated evaluation of drug effects across all major cardiac cell types. By closely reflecting human cardiac tissue biology, the platform supports precise cardiotoxicity screening, advanced cardiovascular disease modelling and efficacy assessment.
TrueCardium® has supported regulatory decision-making at BfArM and the U.S. FDA as part of an integrated nonclinical pharmacology package enabling clinical entry of a novel chemical entity. Alongside peer-reviewed translational studies, this highlights the platform’s readiness to advance cardiac safety and efficacy determination.

Its scalability, reproducibility, and predictive value make it an essential tool for:
TrueCardium® system uses patient-derived induced pluripotent stem cells (iPSCs) to create three-dimensional cardiac organoids containing cardiomyocytes, vasculature, and neuronal elements.

Modeling NCE, anthracycline and other drug-related cardiac-tissue toxicity.

Lipid accumulation, oxidative stress, and fibrotic remodeling.

Immune-triggered structural changes (e.g., LPS, cytokine exposure, CHIP).

Hypoxia-induced damage mimicking myocardial infarction and heart failure.

Energy-metabolism defects leading to dilated-cardiomyopathy phenotypes.

Modeling Rare and Orphan diseases for drug discovery and validation.
