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.

Cardiac Safety Early Career Seminar Award Series

The HESI Cardiac Safety Committee seeks Postdoctoral or Early Career Researchers working in cardiovascular safety science or a related field for the 2023 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.

  • Award: Selected candidates will receive a $500.00 USD award and be invited to present their research on a public webinar with HESI Cardiac Safety Committee scientists and other invited guests. Webinar dates will be scheduled with the awardees in Q1 2023.
  • Qualifications and Requirements: Eligible candidates must have a PhD or equivalent degree in biology or related field (cell biology, biochemistry, pathology, biomechanical engineering, or similar); have current post-doc position/appointment or consider themselves an early career scientist (~1-5 years post-academic training) and may not have previously received an award under this program. Open to both domestic and international applicants.
  • Application: Submission cycle has closed for this award.

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.

  • 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.

    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.

  • 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).

  • 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 2022.

  • FDA U01 Validating Stem Cell Technology

    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.”

  • FDA BAA Ion Channel Patch Clamp Study

    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.

The Challenges of Predicting Drug-Induced QTc Prolongation in Humans

Toxicological Sciences, 2022

Jean-Pierre Valentin, Peter Hoffmann, Catherine Ortemann-Renon, ...

New publication in Toxicological Sciences by the HESI Cardiac Safety Committee shows that nonclinical models used to predict cardiac safety during drug development do not absolutely replicate the clinical conditions; however, best practices can be used to improve the nonclinical assay quality and achieve the ...

Use of the ZDF Rat to Model Dietary Fat Induced Hypercoagulability is Limited by Progressive and Fatal Nephropathy

Journal of Pharmacological and Toxicological Methods, 2021

Pugsley MK, Brooks MB, Fishman CE, Katavolos P, Chiang AY, ...

Zucker diabetic fatty (ZDF) rats are used widely as an animal model of metabolic syndrome and insulin resistance. Our study focused on the effects of high versus low dietary fat on the development of Type 2 diabetes in obese male ZDF rats (fa/fa), including biomarkers to detect early signs of hypercoagulability and vascular injury ...

Repolarization Studies Using Human Stem Cell-Derived Cardiomyocytes: Validation Studies and Best Practice Recommendations

Regulatory Toxicology and Pharmacology, 2020

Gintant G, Kaushik EP, Feaster T, Stoelzle-Feix S, Kanda Y, ...

Human stem cell-derived cardiomyocytes (hSC-CMs) hold great promise as in vitro models to study the electrophysiological effects of novel drug candidates on human ventricular repolarization. Two recent large validation studies have demonstrated the ability of hSC-CMs to detect drug-induced delayed ...

Echocardiographic and Hemodynamic Indices of Myocardial Contractility Simultaneously Evaluated in Telemetered Beagle Dogs: A HESI-Sponsored Cross-Company Evaluation

Journal of Pharmacological and Toxicological Methods, 2020

Rossman EI, Cools F, Cordes J, Dhuyvetter D, Doyle JM, ...

Alterations in cardiac contractility can have significant clinical implications, highlighting the need for early detection of potential liabilities. Pre-clinical methods to assess contractility are typically invasive and their translation to human measures of cardiac function are not well defined. Clinically, cardiac ...

Cross-Site and Cross-Platform Variability of Automated Patch Clamp Assessments of Drug Effects on Human Cardiac Currents in Recombinant Cells

Nature Scientific Reports, 2020

Kramer J, Himmel HM, Lindqvist A, Stoelzle-Feix S, Chaudhary KW, ...

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 ...

Electrophysiological Characterization of Drug Response in hSC-Derived Cardiomyocytes Using Voltage-Sensitive Optical Platforms

Journal of Pharmacological and Toxicological Methods, 2019

Pfeiffer-Kaushik ER, Smith GL, Cai B, Dempsey GT, ...

Voltage-sensitive optical (VSO) sensors offer a minimally invasive method to study the time course of repolarization of the cardiac action potential (AP). This Comprehensive in vitro Proarrhythmia Assay (CiPA) cross-platform study investigates protocol design and measurement variability of VSO sensors for ...
