To provide a more thorough and predictive cardiac safety profile of new chemical entities, the FDA is introducing the Comprehensive in vitro Proarrhythmia Assay (CiPA) initiative. To allow the successful integration of human induced pluripotent stem cell-derived cardiomyocytes (iPSC-CM) as a translational model of human cardiac tissue their physiology needs to be fully characterised.
Here we highlight the work performed at Metrion Biosciences in collaboration with Cellular Dynamics International (CDI) to assess the utility of CDI iCell2 ventricular iPSC-CM for cardiotoxicity screening.
The HESI Cardiac Safety Committee present results from an international ion channel research study that assessed the variability of hERG data generated using automated patch clamp platforms (QPatch 48, Qube 384 and the SyncroPatch 384i) across four different labs.
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).
