Cross-Site Reliability of Human Induced Pluripotent Stem-Cell Derived Cardiomyocyte Based Safety Assays using Microelectrode Arrays: Results from a Blinded CiPA Pilot Study
Toxicological Sciences, 2018
The mission of the HESI Cardiac Safety Committee is to improve public health by reducing unanticipated cardiovascular-related adverse effects from drugs or chemicals, and to develop innovative approaches to support early detection and prediction as well as improved understanding of cardiovascular toxicology and pathobiology.
The HESI Cardiac Safety Committee seeks Postdoctoral or Early Career researchers working in cardiovascular safety science or related field for the Early Career Seminar Award Series. This award offers an opportunity to share your research, learn from and network with experts in the toxicology and safety pharmacology fields from academia, regulatory agencies and pharmaceutical companies.
This group is working to understand and characterize use of stem cell–derived cardiomyocytes in cardiac safety assessments. An article that included best practices for use of stem cell cardiomyocytes in cardiac safety assessments was published in Regulatory Toxicology and Pharmacology. A new group is planning a study to explore in vitro assay ability to detect cardiotoxicity.

This working group is dedicated to investigating mechanisms of proarrhythmic risk. They continue to collaborate with the CiPA Initiative and ICH, and recently published its anticipated high throughput systems (HTS) ion channel work. A new subteam is scoping a conduction/ sodium channel paper to discuss the history and challenges surrounding this topic.
A 3-phased project was conducted by the HESI Pro-Arrhythmia Working Group starting with a detailed literature review and followed by a collaborative HESI-FDA database of 150 new drug candidates to evaluate how predictive nonclinical studies are to clinical outcomes.

This working group has examined the sensitivity within a preclinical species to assess the function of contractility. They continue their partnership with University of Surrey and Imperial College London on a mathematical model to predict blood pressure changes. The Implanted Telemetry Subteam explored the impact of telemetry lead placement in toxicology studies (a collaboration with the Pro-Arrhythmia Working Group).

This working group is dedicated to investigating preclinical cardiac biomarkers of hypercoagulability induced under a thrombotic state, in both normal and diseased states. A manuscript was submitted detailing a study investigating the effects of doxorubicin in Zucker diabetic fatty rats. A new study is in the planning stages using xenobiotics to induce the procoagulant state and confirm measurements of biomarkers of interest.

The Cardiac Safety Steering Team established this subteam in early 2020 to develop and provide a structured resource for use when identifying compounds appropriate in a planned committee study. The database was published April 2024.

HESI has been awarded a multi-year U01 grant from the US FDA on the “Evaluation of Integrated Human-Relevant Approaches to Identify Drug Induced Cardiovascular Liabilities.” This grant supports HESI in funding and managing novel, in vitro experimental studies to develop targeted mechanistic data to inform drug safety assessment for key cardiac “failure modes.”
HESI received a Broad Agency Announcement (BAA) award from the US FDA to manage a multi-site study on manual and automated patch clamp platforms. The original study included 4 ionic currents (hERG, Nav1.5 peak, Nav1.5 late and Cav1.2) and 14 compounds and has been expanded to include a total of 28 compounds. The project aims to collect additional information on inter-laboratory variability as well as support the FDA in silico model.

Automated patch clamp (APC) instruments enable efficient evaluation of electrophysiologic effects of drugs on human cardiac currents in heterologous expression systems. Differences in experimental protocols, instruments, and dissimilar site procedures affect the variability of IC50 values characterizing drug block ...
Frontiers in Pharmacology, 2019
Contractility of the myocardium engines the pumping function of the heart and is enabled by the collective contractile activity of its muscle cells: cardiomyocytes. The effects of drugs on the contractility of human cardiomyocytes in vitro can provide mechanistic insight that can support the prediction of clinical cardiac drug ...
Frontiers in Pharmacology, 2019
Drug-induced effects on cardiac contractility can be assessed through the measurement of the maximal rate of pressure increase in the left ventricle (LVdP/dtmax) in conscious animals, and such studies are often conducted at the late stage of preclinical drug development. Detection of such effects earlier in drug research using ...

Cardiac troponin (cTn) has been utilized to assess acute myocardial injury, but the cTn response in active/ongoing chronic injury is not well documented.
