We demonstrate the generation and validation of a stable CHO-hHCN2 cell line used as a cellular tool in the successful development of hHCN2 automated electrophysiology screening assays.
Human induced pluripotent stem cell-derived cardiomyocytes (iPSC-CM) are a promising tool for assessment of drug-induced arrhythmias during non-clinical drug development. This technology is under evaluation by the FDA’s Comprehensive in vitro Proarrhythmia Assay (CiPA) initiative and the Japanese iPS Cardiac Safety Assessment consortium (JiCSA) to develop new cardiac safety assessment measures to refine current S7B and E14 guidelines. The CiPA myocyte working group utilises imaging and electrophysiology platforms and a toolbox of 28 clinical compounds with known arrhythmia risk to correlate in vitro iPSC-CM data with clinical QT prolongation and Torsade de Pointes (TdP) liabilities.

We have developed a robust high-throughput automated electrophysiology assay using a monoclonal CHO-hNav1.9 cellular reagent suitable for fully supporting a Nav1.9 discovery program.
