Central Nervous System is the processing centre of the body and consists of the brain and the spinal cord. Both of these are protected by three layers of membranes known as meninges.

Liver is the largest internal organ in the body. It is essential for digestion of food and elimination of toxic substances from the body. Liver problems can be caused by a variety of genetic and non genetic factors such as viruses, alcohol use and obesity. Damage of the liver can lead to liver failure, and a build up of toxin in the blood leading to life threatening conditions.

Skeletal muscles (commonly referred to as muscles) are organs of the vertebrate muscular system that are mostly attached by tendons to bones of the skeleton. The muscle cells of skeletal muscles are much longer than in the other types of muscle tissue, and are often known as muscle fibers. The muscle tissue of a skeletal muscle is striated – having a striped appearance due to the arrangement of the sarcomeres.

2016

First human mini-Heart models of Friedreich’s Ataxia was created by the collaboration of Novoheart and Pfizer

Friedreich’s ataxia (FRDA) is a hereditary neuromuscular degenerative disease that affects over 1 in 50,000 people worldwide. FRDA patients have a defective Frataxin gene, which often leads to lethal heart complications. In 2016, Novoheart teamed up with Pfizer’s Rare Disease Unit to generate a species-specific, functional in vitro experimental models of FRDA using our mini-Heart technology. The new disease models were created using genetically modified as well as FRDA patient-derived cells, capturing both electrical and mechanical defects of the heart observed in FRDA patients. This new approach marks an important step away from using animals as traditional testing models which have limited predictive ability for drug discovery due to dramatic differences in both the genetics and physiology.

In 2018, Novoheart filed a patent application based on our proprietary mini-Heart Platform of human bioengineered heart tissues to create disease models for ataxia affecting the heart. The disease models will benefit patients and drug developers by providing a unique and robust platform for testing candidate therapeutics.

Novoheart and Pfizer subsequently co-published the result of the study in 2019.

2014

Pfizer and Novoheart undertook a double-blinded drug screening study using the mini-Heart technology

In 2014, Novoheart collaborated with Pfizer’s Global Safety Pharmacology Unit to systematically examine the pharmacological responses of engineered human ventricular-like Cardiac Tissue Strips (hvCTS) and Organoid Chambers (hvCOC) of the mini-Heart technology, to 25 cardioactive compounds covering various drug classes. We further quantified the predictive capacity of our mini-Heart technology in a blinded screening, with accuracies for negative, positive, and null inotropic effects at 100%, 86%, and 80%. Our healthy “human heart-in-a-jar” confirmed the results and further revealed that the more adult-like heart characteristics result in a greater sensitivity to positive inotropic drugs that stimulate cardiac contractility. The findings led to a two-tiered screening strategy that can provide an improved drug discovery approach to better predict clinical outcomes. Since the publication of this study in 2019, the accuracy for all 3 classes of inotropes have now reached 100%.

Intracoronary delivery in pre-clinical pig models of heart failure by Dr. Roger Hajjar

In 2005, Dr. Roger Hajjar further developed the gene delivery technique and subsequently translated it to a pig model of heart failure, showing a reversal of cardiac dysfunction after intracoronary delivery (i.e., directly into the heart through the coronary arteries) of a recombinant adeno-associated virus (AAV). The success in the pig model, whose cardiovascular system is similar to human, formed the basis of the FDA-approved delivery protocol that Sardocor is using today for patients.

Patented technology for driving maturation of human heart cells by Dr. Ronald Li’s team

In 2007, Dr. Ronald Li’s team patented an invention for driving the maturation of stem cell-derived human heart cells. Like a molecular time tunnel, this invention facilitates the use of these heart cells for drug screening and heart regeneration.

In 2014, the team patented another technology for driven maturation of stem cell-derived human heart cells without the need for genetic manipulation. These two inventions form the basis of our collaboration with Stanford University and AstraZeneca today.

human ventricular Cardiomyocytes (hvCMs)

Medera’s human ventricular Cardiomyocytes (hvCMs) are terminally differentiated cardiomyocytes derived from human pluripotent stem cells (hPSCs) using Medera’s proprietary differentiation method. These cells have been extensively characterized for their electrophysiology, calcium homeostasis, transcriptome, microRNAome, and proteome.

They exhibit ventricular-like action potentials and express ventricular-specific myosin light chain MLC2v. With virtually homogeneous ventricular properties, these cells provide the consistency necessary to achieve reliable and reproducible results in downstream applications.

human ventricular Cardiac Tissue Strip (hvCTS)

Contractile performance is an essential function of the human heart, yet conventional 2-D cardiomyocyte cultures are inadequate for assessing contractility as they cannot perform physiological contractions on rigid plasticware. Tissue engineering offers a superior contractile assay in the form of Medera’s human ventricular Cardiac Tissue Strip (hvCTS), which is structurally and functionally similar to native trabecular muscle. This assay consists of aligned hvCMs in 3-D hydrogel mixture that is constructed using Medera’s custom-designed bioreactor with integrated force-sensing posts at the ends. This model has been validated as a sensitive and reliable predictor of clinical effects of drugs or pathologies on cardiac contractility.

human ventricular Cardiac Anisotropic Sheet (hvCAS)

Effective modelling of arrhythmias in vitro is challenging: by definition they are multicellular events that can only be recorded by monitoring conduction patterns in electrically coupled cardiomyocytes. Conventional assays can only use surrogate markers for arrhythmia: the hERG assay, standard in the industry, for example, uses inhibition of a single potassium channel exogenously expressed in non-cardiac cell lines as an indicator for proarrhythmic risk. Although these remain the standard tests for arrhythmogenicity, global drug regulators recognize their pitfalls and are actively seeking better alternatives, notably in the Comprehensive in vitro Proarrhythmia Assay (CiPA) initiative of the FDA. Human pluripotent stem cell-derived cardiomyocytes are inherently prone to arrhythmic events when cultured as randomly oriented monolayers. Medera’s human ventricular Cardiac Anisotropic Sheet (hvCAS) assay utilizes specially designed microgrooved substrates that physically guide hvCMs to align in a similar manner to that in the native human ventricle. The aligned cells show anisotropic electrical conduction which has been validated to reduce the baseline arrhythmogenicity compared to monolayers without a cardiomimetic preferential conduction axis.

Partnership with AstraZeneca to co-develop a human mini-Heart model of Heart Failure with preserved Ejection Fraction (HFpEF)

There are two main types of heart failure – Heart Failure with reduced Ejection Fraction (HFrEF) and Heart Failure with preserved Ejection Fraction (HFpEF) which accounts for roughly half of all new cases of heart failure. In recent years, new therapies have been introduced for HFrEF which reduce deaths and hospitalization due to the disease. But these drugs do not work as well in HFpEF. Research is much needed to identify alternative strategies for treating HFpEF, and reliable animal models of the disease are lacking. To achieve this goal, Novoheart has teamed up with AstraZeneca to build preclinical human models of HFpEF designed to understand the disease mechanism, and predict the effects of potential medicines, bringing the most promising agents into clinical trials. This in vitro model builds on Novoheart’s heart-in-a-jar from the mini-Heart technology and will be used to test new therapies.

First demonstration of gene editing to correct inherited cardiomyopathy in an engineered cardiac tissue strip model by Drs. Kevin Costa and Roger Hajjar

Drs. Kevin Costa and Roger Hajjar published a study in the European Heart Journal demonstrating for the first time that gene editing to correct the PLN-R14del mutation in iPSCs from patients carrying this variant of the phopholamban gene was able to restore contractile function of engineered cardiac tissue strips to match tissues from healthy donors. This could lead to new gene therapy strategies for these patients who suffer severe and early onset dilated and arrhythmogenic cardiomyopathy.

First-in-man gene therapy trial for heart failure in the U.S. by Dr. Roger Hajjar

Using the delivery technique invented by Dr. Roger Hajjar at Massachusetts General Hospital/Harvard (Learn more details in 1997), Celladon obtained a US FDA approval in 2007 to launch the world’s first-in-man gene therapy trial to target heart failure by directly injecting an engineered adeno-associated virus (AAV) containing the SERCA gene into the coronary arteries. Having been used by Celladon, Asklepios Biopharmaceutical (AskBio, which was later acquired by Bayer), (Learn more details in 2016) and Sardocor, this delivery method has been proven both safe and effective in human.

Celladon’s trial did not succeed to meet the clinical endpoints, however, because they were using doses, as allowed by FDA at the time, that were as much as 30-100X lower than what are typically used by today’s gene therapy companies. In general, the gene therapy field has advanced very significantly from the lessons learned in the past 20 or so years.

First genetically engineered human heart muscle cells derived from human embryonic stem cell by Dr. Ronald Li’s team

In the beginning of the Millennium, Dr. Ronald Li’s group at the Johns Hopkins University produced the world’s first genetically engineered human embryonic stem cells (hESC)-derived heart cells via lentivirus-mediated bioengineering. This was later awarded the American Heart Association’s Best Basic Study of the Year Award (2005). However, the efficiency of deriving heart cells from hESCs at the time was only 0.5%. This seminal report formed the basis for subsequent studies, including the first to discover the central importance of calcium handling in stem cell-derived cardiomyocyte function, the presence of ion channels in human pluripotent stem cells, the development of methods for mass production of cardiomyocytes, etc.

Vascular

Restenosis is when a part of the artery that was previously treated for blockage becomes narrow again.

Arteriovenous Fistula Failure occurs when the fistula surgically created for hemodialysis treatments is never usable or fails within the first three months of its use.

Pulmonary

Pulmonary hypertension is high blood pressure in the blood vessels that supply the lungs (pulmonary arteries). It occurs when walls of the pulmonary arteries become thick and stiff, and cannot expand as well to allow blood through. The reduced blood flow makes it harder for the right side of the heart to pump blood through the arteries, causing damage to the right heart.

Pulmonary fibrosis means scarring in the lungs. Over time, the scar tissue blocks the movement of oxygen from inside the tiny air sacs in the lungs into the bloodstream, causing people who have pulmonary fibrosis to feel short of breath, particularly when walking and exercising.

Cardiac

Heart failure with preserved ejection fraction (HFpEF) is a form of heart failure with high left ventricular (LV) filling pressure despite normal or near normal LV ejection fraction.

Heart failure with reduced ejection fraction (HFrEF) occurs when the left ventricular ejection fraction (LVEF) is 40% or less and is accompanied by progressive left ventricular dilatation and adverse cardiac remodelling.

Duchenne muscular dystrophy (DMD) is a genetic disorder characterized by progressive muscle degeneration and weakness due to the alterations of a protein called dystrophin that helps keep muscle cells intact.
