Cardiac Safety Committee

Mission Statement

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.

Working Groups

  • Stem Cell Working Group

    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.

    Leadership Team:
    Gary Gintant, PhD (AbbVie)
    Godfrey Smith, PhD (University of Glasgow)

  • Pro-Arrhythmia Working Group

    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.

    Leadership Team:
    John Koerner, PhD (US Food and Drug Administration)
    Jean-Pierre Valentin, PhD (UCB Biopharma)

  • Integrative Strategies Working Group

    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).

    Leadership Team:
    Michael Pugsley, PhD (Cytokinetics)
    Brian Berridge, DVM, PhD (National Institute of Environmental Health Sciences, National Toxicology Program)

    HESI Staff:
    E’Lissa Flores, PhD

  • Cardiac Biomarkers 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.

  • Cardiac Compound Tool (CCT) Database Subteam

    The Cardiac Safety Steering Team established this new subteam in early 2020 to develop and provide a structured resource for use when identifying compounds appropriate in a planned committee study. Delivery of this publicly accessible database is anticipated by the end of 2020.

  • COVID-19 Subteam

    This subteam was organized in May 2020 in response to the ongoing pandemic. Subteam members identified that emerging treatments for the novel coronavirus may have cardiotoxicities. The group is exploring how to gather cardiac safety data on five emerging therapies, whether prospective or retrospective, and develop a publication.

Considerations for an In Vitro, Cell-Based Testing Platform for Detection of Adverse Drug-Induced Inotropic Effects in Early Drug Development. Part 1: General Considerations for Development of Novel Testing Platforms

Frontiers in Pharmacology, 2019

Guth BD, Engwall M, Eldridge S, Foley CM, Guo L, Gintant G, ...

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 ...

A Proof-of-Concept Evaluation of JTPc and Tp-Tec as Proarrhythmia Biomarkers in Preclinical Species: A Retrospective Analysis by an HESI-Sponsored Consortium

International Journal of Toxicology, 2018

Emmanuel Boulay, Matthew M. Abernathy, Ray Chu, ...

Results from this limited retrospective electrocardiogram analysis suggest that JTpca and Tpeca may discriminate selective IKr blockers and multichannel blockers and could be considered in the context of an integrated comprehensive proarrhythmic risk assessment.

The evaluation of endpoint variability and implications for study statistical power and sample size in conscious instrumented dogs.

J Pharmacol Toxicol Methods., 2018

Chiang AY, Guth BD, Pugsley MK, Foley CM, Doyle JM, Engwall MJ, ...

The HESI Cardiac Safety Committee designed and conducted studies to evaluate inherent variability in telemetry implanted dogs. This paper discusses details of the statistical methods used to evaluate a primary endpoint for measuring blood pressure changes.
