• Heart failure is a world pandemic affecting no less than 64 million folks worldwide and costing over US$100B per yr
• Heart failure with preserved ejection fraction (HFpEF) accounts for half of all coronary heart failure circumstances, and is a rising downside with restricted therapy choices
• There is an absence of efficient human-specific fashions for preclinical testing of focused therapeutic candidates for HFpEF
• The Novoheart-AstraZeneca collaboration has efficiently generated the world’s first bioengineered HFpEF miniature human coronary heart fashions
• Forced expression of a down-regulated gene product recognized in HFpEF reverses the illness phenotype in our bioengineered coronary heart fashions
• HFpEF mini-hearts might present a robust instrument for discovery, screening, and development to scientific trials of novel therapeutics for coronary heart failure
Medera Biopharmaceutical (Medera), a clinical-stage gene and cell remedy firm, and Novoheart, its totally owned subsidiary for illness modelling and drug discovery, collectively with AstraZeneca, are delighted to announce that their ongoing collaboration has led to the profitable growth of the world’s first human-specific in vitro, useful fashions of coronary heart failure with preserved ejection fraction (HFpEF), a steadily worsening situation particularly widespread among the many aged.¹
Heart failure (HF) is a world pandemic,² with an rising development in prevalence.³ The annual international financial burden of HF is estimated at over US$100 billion.⁴ HFpEF accounts for roughly 50% of HF circumstances and is a serious and rising public well being downside worldwide. However, the pathological mechanisms and various causes of HFpEF stay poorly understood. Due to those complexities, earlier fashions of the illness, together with numerous investigational fashions, have proven restricted capacity to imitate the scientific presentation of HFpEF.⁵ Therefore, drug builders have lacked predictive instruments for preclinical testing of drug candidates for efficacy. As a outcome, scientific outcomes for HFpEF have hardly improved over the past a number of many years and restricted therapy choices can be found to sufferers.
Medera’s Novoheart has labored with the Cardiovascular, Renal and Metabolism remedy space of AstraZeneca to make use of its proprietary mini-Heartᵀᴹ Platform for human cardiac tissue engineering to efficiently set up novel in vitro fashions that reproduce key phenotypic traits, together with rest defects, fibrosis and hypertrophy, as seen in HFpEF sufferers. Also referred to as “human heart-in-a-jar”, the 3-D human ventricular cardiac organoid chamber (hvCOC) is the one human-engineered coronary heart tissue accessible on the market that allows clinically informative assessments of human cardiac pump efficiency together with ejection fraction and developed strain.⁶ Unlike animal fashions, engineered human heart-in-a-jar could be fabricated with particular mobile and matrix compositions, and patient-specific human induced pluripotent stem cells (iPSCs), that enable management over the bodily and mechanical properties to uniquely mimic these noticed in HFpEF affected person hearts. Novoheart has additionally developed human cardiac fiber-like HFpEF cardiac tissue strips (CTS) that recapitulate the results of HFpEF on cardiac muscle stiffness and contractility.
To facilitate the analysis, Novoheart has additionally developed CTScreenᵀᴹ proprietary {hardware} and software program for automation that will increase the throughput, accuracy and sensitivity of phenotypic and drug screening experiments utilizing the engineered human heart-in-a-jar and hvCTS assays.
Collectively, these progressive HFpEF human coronary heart fashions and associated instruments have supplied a singular assay for understanding the mechanisms of HFpEF, figuring out new therapeutic targets, and assessing novel therapeutics for treating HFpEF sufferers. Novoheart solely owns the mental property rights to the newly developed HFpEF fashions. This work is being submitted for publication in a peer-reviewed scientific journal.
“These new HFpEF versions of our human heart-in-a-jar and hvCTS assays, developed in our ongoing collaboration with AstraZeneca, demonstrate the capability and versatility of Novoheart’s mini-Heartᵀᴹ Platform for modelling complex acquired diseases such as heart failure, that are even more challenging than well-defined and rare genetic mutations,” stated Novoheart CSO, Dr. Kevin Costa.
Regina Fritsche Danielson, Senior Vice President, Head of Research and Early Development, Cardiovascular, Renal and Metabolism, BioPharmaceuticals R&D, AstraZeneca, stated, “At AstraZeneca, we recognize the urgent need to learn more about the underlying mechanisms of HFpEF in our ambition to develop targeted therapies for this population of patients. Our collaboration with Novoheart to build the first in vitro HFpEF models will help us bridge the gap between animal models and clinical trials to accelerate the drug discovery process by providing human-specific preclinical data.”
“The US FDA Modernization Act 2.0 aims to accelerate innovation and get safer, more effective drugs to patients more quickly by encouraging the use of scientifically superior, human-based technologies to replace animal testing for improved human accuracy and therefore better successes. Along this line, we are totally excited about the new HFpEF human mini-heart models. We are now focusing on their translation into tangible patient benefits,” stated Medera CEO, Dr. Ronald Li.

Medera
Founded in 2014, Medera is a number one clinical-stage firm devoted to next-generation therapeutics for difficult-to-treat and incurable ailments. Medera has two subsidiaries, Novoheart and Sardocor. Novoheart capitalizes on the world’s first and award-winning “mini-Heart” Technology for revolutionary illness modelling and drug discovery, enabling us to uniquely mannequin human-specific ailments and uncover therapeutic candidates free from species-specific variations. Before privatisation by Medera, Novoheart was dually listed on the Toronto Stock Exchange and Frankfurt Stock Exchange. Sardocor aspires to create the shortest regulatory path to clinic for advancing next-generation cell and gene therapies. Building upon Novoheart’s bioengineered human tissue-based assays for illness modelling and drug discovery, Sardocor has developed one of the world’s largest gene and cell-based therapeutic pipelines for a variety of cardiac, vascular and muscular ailments together with coronary heart failure with preserved ejection fraction, Duchenne muscular dystrophy and pulmonary hypertension.
