Tissue Dynamics and Galmed Unveil Unknown Metabolic Pathway for Cardiac Fibrosis and Heart Failure which Supports the Development of Aramchol for Cardiac Fibrosis

- Tissue Dynamics identified a previously unrecognized metabolic mechanism driving cardiac fibrosis using a human cardiac organoid model, revealing disease biology that is not accessible through conventional animal models.

- In inflammatory human cardiac organoids, the combination of Aramchol Meglumine and a selective PPARα agonist reduced fibrotic burden by approximately 4-fold (p<0.001) while preserving cardiac muscle integrity and metabolic function.

REHOVOT, Israel and RAMAT-GAN, Israel, June 2, 2026 /PRNewswire/ -- Tissue Dynamics Ltd. and Galmed Pharmaceuticals Ltd. (NASDAQ: GLMD) ("Galmed" or the "Company"), a clinical-stage biopharmaceutical company focused on liver, cardiometabolic, and GI oncology diseases, today announced results from a preclinical study evaluating a combination of Aramchol Meglumine, an SCD1 inhibitor, and a selective PPARα agonist. The study identified a previously unrecognized metabolic pathway involved in the progression of cardiac fibrosis and heart failure and demonstrated that the two-drug combination effectively targets this mechanism.

Progressive cardiac fibrosis, driven by ischemic injury or age-related metabolic dysfunction, results in pathological scarring of the heart muscle, leading to tissue stiffening and impaired systolic and diastolic function. Cardiac fibrosis is a major contributor to heart failure progression and remains an area of significant unmet medical need. Despite advances in cardiovascular care, no therapies directly reverse established cardiac fibrosis, highlighting the need for novel therapeutic approaches.

One of the major challenges in cardiac drug development is the substantial physiological and metabolic differences between rodent and human hearts. As a result, findings from animal models often fail to translate successfully into human clinical outcomes. Using its robotic DynamiX® platform and advanced human cardiac organoid models, Tissue Dynamics identified a novel human-specific metabolic mechanism that would not have been readily detectable using conventional animal models.

The study demonstrated that a combination of Aramchol Meglumine and a selective PPARα agonist modulates two key pathological processes--mitochondrial stress and associated lipogenesis--that contribute to the development and progression of cardiac fibrosis and heart failure. Leveraging Tissue Dynamics' machine-learning platform, researchers identified and validated a previously unknown metabolic pathway underlying the synergistic effects of the combination therapy. In inflammatory human cardiac organoids, the treatment reduced fibrotic burden by approximately fourfold (p<0.001) while preserving cardiac muscle density and maintaining metabolic function. Based on these findings, a new patent application has been filed, and preparations are underway to support future IND-enabling activities.

Allen Baharaff, Co-Founder, President, and Chief Executive Officer of Galmed, commented: "Our collaboration with Tissue Dynamics is helping shape the next generation of Galmed's research and development strategy and supports our broader vision of developing innovative therapies for cardiometabolic, fibrotic, and GI oncology diseases. By combining advanced AI technologies with highly predictive human organoid models, we are gaining unprecedented insights into human disease biology and cardiac physiology. We believe this collaboration has the potential to identify additional therapeutic opportunities and drug combinations for fibrotic diseases beyond the heart. We look forward to engaging with regulatory authorities to define the most efficient path toward clinical development of this program."

Dr. Avner Ehrlich, Chief Executive Officer of Tissue Dynamics, commented: "Tissue Dynamics has developed a human cardiac organoid model designed to capture key aspects of human cardiac complexity, including multiple chambers, vascular structures, an epicardial layer, an endocardial lining, and pacemaker cells. This model recapitulates both the inflammatory and proliferative phases of cardiac fibrosis following myocardial infarction and has been extensively validated through genetic, functional, and pharmacological studies. Combined with our MechaniX® artificial intelligence platform, these models enable the generation of highly predictive efficacy and safety data while providing mechanistic insight into drug action through explainable AI and in silico experimentation."
