First-ever mini-Heart models will be created from hypoplastic left heart syndrome (HLHS) patient stem cells, enabling personalized insights into their causes and treatmentsPartnership aims to improve survival and quality of life for pediatric HLHS patients by developing new tools that can identify which children will potentially benefit most from surgery, transplantation, or novel therapiesLeveraging Novoheart’s proprietary mini-Heart Platform, this partnership aligns with emerging FDA guidelines supporting human-relevant, animal-free drug development BOSTON and SAN DIEGO and ROCHESTER, Minn., June 24, 2025 (GLOBE NEWSWIRE) — Medera Inc. (“Medera”), a clinical-stage biopharmaceutical company focused on targeting cardiovascular diseases by developing a range of next-generation therapeutics, and Novoheart, its wholly owned pre-clinical subsidiary pioneering human-based cardiac tissue engineering for disease modelling and drug screening, today announced a groundbreaking collaboration with physician-scientists at the University of California San Diego School of Medicine and Mayo Clinic. The goal of the partnership is to develop the first human mini-heart models of hypoplastic left heart syndrome (HLHS) using stem cells from real patients and improve the understanding of this disease with the goal of developing more personalized treatment strategies for children born with this devastating condition. “There is currently no reliable way to predict which HLHS patients will benefit from surgery versus needing a transplant,” said Paul Grossfeld, MD, Clinical Professor of Pediatrics at University of California San Diego School of Medicine, pediatric cardiologist at Rady’s Children’s Hospital-San Diego, and a leading expert on HLHS. “By generating patient-specific 3D human heart models from a simple blood draw, we aim to uncover the biological mechanisms driving disease in each child—and ultimately tailor treatments that improve their chances of survival.” The project leverages Novoheart’s proprietary mini-Heart Platform, a suite of 3D bioengineered cardiac tissues and chambers that replicate human heart structure and function more faithfully than animal models or traditional cell cultures. In combination with customized hardware- and software-based automated screening, the team will evaluate heart function using mini-Heart models derived from patient stem cells from HLHS patients and their healthy relatives. Key to this initiative is Mayo Clinic’s HLHS biobank, comprised of samples from more than 800 HLHS patients and family members and developed over the past 25 years under Timothy Nelson, MD, PhD, Director of the Todd and Karen Wanek Family Program for Hypoplastic Left Heart Syndrome. While a minority of HLHS cases can be traced to specific genetic mutations, the majority remain poorly understood. Current models fall short: animal hearts differ significantly from human hearts, and flat (2D) cultures of patient cells or a simpler conventional heart-on-a-chip cannot reproduce the 3D complexity of heart chambers. Novoheart’s technology, which has previously created congenital heart disease (CHD) models such as Pulmonary Atresia, Tetralogy of Fallot, DiGeorge Syndrome, and Hypoplastic Right Heart Syndrome, addresses these challenges. “This collaboration allows us to test how well our patient-specific disease models can predict treatment responses in the most complex pediatric heart disease we know,” said Kevin Costa, PhD, co-founder of Novoheart. “It’s the first step toward bringing personalized cardiac care to children with HLHS—especially those without known genetic mutations.” Ronald Li, PhD, CEO and co-founder of Medera and Novoheart, added, “We’re proud to support this effort and confident that our mini-Heart Platform will once again demonstrate its predictive power. By building human-relevant disease models, Medera is accelerating the path to better therapies—without relying on animal testing—and aligning with the latest FDA regulatory science.” This project has also been made possible by the generous support of the John Dimitri Research Foundation for Congenital Heart Disease and Big Hearts 2 Little Hearts. On September 5, 2024, Medera and Keen Vision Acquisition Corporation (“KVAC”) (NASDAQ: KVAC, KVACW), announced they had entered into a definitive merger agreement. About Hypoplastic Left Heart Syndrome Each year, approximately 2,000 babies in the U.S. are born with HLHS, a severe form of congenital heart disease (CHD) in which the left side of the heart is critically underdeveloped. Though HLHS accounts for just 3% of CHD cases, it is responsible for up to 25% of deaths in this population. Even with current surgical advances, half of all HLHS patients will not survive past age 16. About Medera Medera is a clinical-stage biopharmaceutical company focused on targeting difficult-to-treat and currently incurable diseases by developing a range of next-generation therapeutics. Medera operates via its two preclinical and clinical business units, Novoheart and Sardocor, respectively. Novoheart capitalizes on the world’s first and award-winning “mini-Heart” Technology for revolutionary disease modelling and drug discovery, uniquely enabling the modelling of human-specific diseases and discovery of therapeutic candidates free from species-specific differences in accordance to the FDA Modernization Act 2.0. Novoheart’s versatile technology platform provides a range of state-of-the-art automation hardware and software as well as screening services, for human-specific disease modelling, therapeutic target discovery and validation, drug toxicity and efficacy screening, and dosage optimization carried out in the context of healthy and/or diseased human heart chambers and tissues. Global pharmaceutical and academic leaders are using Novoheart’s technology platform for their drug discovery and development purposes. The Novoheart platform has facilitated and accelerated the development of Sardocor’s lead therapeutic candidates that are currently in clinical trials. Sardocor is dedicated to the clinical development of novel next-generation therapies for Medera. Leveraging Novoheart’s human-based drug discovery and validation platforms, Sardocor aims to expedite drug development and regulatory timelines for its gene and cell therapy pipeline. Sardocor has received Investigational New Drug (IND) clearances from the FDA for three ongoing AAV-based cardiac gene therapy clinical trials targeting Heart Failure with Reduced Ejection Fraction (HFrEF), Heart Failure with Preserved Ejection Fraction (HFpEF) with the Fast Track Designation, and Duchenne Muscular Dystrophy-associated Cardiomyopathy (DMD-CM) with the Orphan Drug Designation. Additionally, Sardocor’s pipeline includes four preclinical gene therapy and three preclinical small molecule candidates targeting various cardiac, pulmonary, and vascular diseases.
