Event Abstract Back to Event CiPA Validation of Human iPSC-derived Cardiomyocytes Using MEA Recording – Assessment of 28 Blinded Compounds Ralf F. Kettenhofen1*, Greg Luerman2 and Tessa De Korte3 1 Ncardia (Germany), Germany 2 Ncardia USA, United States 3 Ncardia (Netherlands), Netherlands Microelectrode array (MEA) recordings were part of the HESI/CSRC/FDA Comprehensive in vitro Proarrhythmia Assay (CiPA) initiative to validate hiPSC-derived cardiomyocytes (hiPSCM) using 28 compounds with known clinical risk to induce Torsade des Pointes tachyarrhythmias (of high, medium or low risk). The data from these studies will be used to generate a statistical prediction model models to assess unknown compounds. Here we show our data from the all, recently unblinded 28 test compounds that were acquired on the Axion Maestro 96 well microelectrode array. In summary, the positive control, 3 nM Dofetilide, was strikingly reproducible as it produced a very consistent FPDc prolongation of 30% to 40% across all 7 MEA plates (with no EADs). Additionally, we show data from all 28 compounds, including FPD prolongation and quantified the number of wells eliciting pro-arrhythmic responses (early afterdepolarizations, tachycardia, etc). The results reveal the predictive value of hiPSCM to assess in vitro the risk of drug-induced Torsade des Pointes in the clinic.
