The FDA’s Comprehensive in vitro Proarrythmia Assay (CiPA) initiative aims to provide a thorough preclinical cardiac safety profile of new chemical entities that enables prediction of human clinical proarrhythmia risk. To allow the successful utilisation of commercial human iPSC-derived cardiomyocytes (iPSC-CM) as models of human CM in the CiPA safety paradigm, their biophysical and pharmacological profile needs to be fully characterised. Here we will highlight our work to assess the utility of Axiogenesis vCor.4U iPSC-CM for CiPA-relevant cardiotoxicity screening.
We developed a high-throughput, electrophysiological assay of TREK-1 function to identify novel modulators. The assay was optimized to identify both activators and inhibitors, providing comprehensive mechanistic data for high value, limited supply screening libraries, such as the venom fraction library used in this study (Targeted Venom Discovery Array, T-VDA, Venomtech, UK).
