CiPA: Novel Cardiac Safety Initiative
Led by HESI, FDA, and the Safety Pharmacology Society
Traditional cardiac safety testing relies on hERG and QT assessments, which alone are insufficient to predict arrhythmia risk. The Comprehensive In Vitro Proarrhythmia Assay (CiPA) initiative advances ICH S7B guidelines by integrating multi-ion channel analysis, in silico modeling, human iPSC-derived cardiomyocytes, and clinical electrophysiology.
Agilent Support for CiPA
Agilent’s xCELLigence RTCA CardioECR system was selected as a core technology for CiPA Phase I and II validation studies (36 compounds total). These studies demonstrated robust sensitivity, specificity, and reproducibility of hiPSC-cardiomyocyte assays for detecting proarrhythmic risk.
Easy, Flexible Workflow
No cell labeling required. Simply seed cells, monitor function in real time, and evaluate drug efficacy, mechanism, and cardiotoxicity - streamlining cardiac safety testing with human-relevant biology.
CiPA Myocyte Pilot Study
Published CiPA Myocyte Pilot Study results confirm hiPSC-derived cardiomyocytes as a predictive, scalable platform for cardiac safety assessment. Using CardioECR, Agilent validated concentration-dependent electrophysiological effects and arrhythmia-related events consistent with known ion-channel mechanisms.
