Using automated patch clamp technology, we evaluate the potency and selectivity of ten Nav1.7-selective arachnid peptide toxins, which have been fused to the C-terminus (Fc region) of human IgG1.
Cardiac toxicity remains the leading cause of new drug safety side-effects. Current preclinical cardiac safety assays rely on in vitro cell-based ion channel assays and ex vivo and in vivo animal models. These assays provide an indication of acute risk but they do not always predict the effect of chronic compound exposure, as recently seen with oncology drugs. Therefore, new assays are required to characterise chronic structural and functional effects in human cells earlier in drug discovery. Impedance-based technology can provide more accurate chronic cardiotoxicity measurements in an efficient manner using human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs).

Understanding cardiac safety early is critical in drug development. In their latest poster, Jazz Pharmaceuticals, explain how they utilised Metrion’s clinically translatable cardiotoxicity assay to do exactly that.
