摘要: Abstract Introduction The comprehensive in vitro proarrhythmia assay (CiPA) is a nonclinical, mechanism-based paradigm for assessing drug proarrhythmic liability. Topics covered first CiPA determines effects on cloned human cardiac ion channels. second investigates whether the latter study-generated metrics engender markers computationally reconstructed ventricular action potential. third evaluates conclusions from, and searches possibly missed by silico analysis, stem cell-derived cardiomyocytes (hSC-CMs). ad hoc Expert-Working Groups have proposed patch clamp protocols seven channels, modified O'Hara-Rudy model detailed procedures field (MEA) potential (VSD) measurements hSC-CMs, 29 reference drugs testing validation. Discussion adoption as development tool identifying electrophysiological mechanisms conferring liability to candidate complex, multi-functional task requiring significant time, reflection, efforts be fully achieved.
