Aptuit LLC's Electrophysiological Technology Platforms Feature Herg Channel Screenings for Faster, High Quality Data

Published: Mar 14, 2013

Greenwich, CT, March 14, 2013 – Aptuit LLC announced the availability of Rapid Ion Channel Electrophysiology (ICE) screening of a high number of compounds on the recombinant human ERG (hERG) channel by using automated patch-clamp platforms such as PatchXpress and QPatch HTX. In discussing this capability, it was emphasized that Aptuit can provide exceptional hERG channel screenings, distinguished by extremely fast turnaround time in generating high quality data, and providing analysis and reporting.

Stuart Needleman, Aptuit’s President and Chief Operating Officer said, “Our legacy and experience in overcoming the challenges associated with cardiovascular targets representing a potential liability includes the screening of novel compounds on the hERG channel. We have a substantial record of success and extensive experience in achieving high quality data, economically, efficiently and in record time, reducing attrition by the fast progress we can make in lead optimization projects. Pharma companies looking to outsource hERG channel screening services can have the utmost confidence in Aptuit's abilities in mastering electrophysiological technology, and specifically in hERG platforms.”

Dr. Caterina Virginio, Head of the Electrophysiology Laboratory at The Aptuit Center for Drug Discovery & Development in Verona, Italy, cited the distinction in the hERG channel screening that Aptuit provides as compared to similar CRO offerings. “To reduce the loss of compound that could lead to potency underestimation, we handle compound solutions in glass; then we can follow up the compound assessment with manual patch-clamp technology and apply different assay conditions at physiological and room temperature. Our clients stand to benefit from our scientific knowledge of the cardiovascular area and the fast results that we achieve from the testing process. Of course, our integrated and comprehensive services allow for follow up with further preclinical in vitro and in vivo studies as required.”

Dr. Virginio stated that typically, the hERG channel assay conditions include three concentrations for the test compound; at least three replicates and positive and negative controls – all in a one week turnaround time. She added that the testing of the compound’s liability on the hERG channel using the same electrophysiology platform can be extended to hNav1.5 and hCav1.2 channels, main cardiac ion targets. The liability panel that consists of hERG, hNav1.5 and hCav1.2 channels complements the integrated risk assessment for cardiac liability potential of compounds, as recommended by ICH Topic S 7 B, The Nonclinical Evaluation of the Potential for Delayed Ventricular Repolarization (QT Interval Prolongation) by Human Pharmaceuticals.

Mr. Needleman concluded, “We want to make sure that pharma companies know that they can turn to us for sophisticated studies based on a reliable and distinctive legacy of specific experience with key electrophysiological technology platforms and our vast knowledge in the cardiovascular therapeutic area.”
