A drug's propensity to cause QT prolongation has to be carefully evaluated in the course of clinical development, and until recently, regulators have required a designated study, the thorough QT (TQT) study, to rule out a small QT effect. It has however become increasingly clear that the TQT study is overly sensitive and results in a number of false positives, i.e. drugs that are labelled as causing clinically relevant QT prolongation based on a very small effect, which is unlikely to be proarrhythmic.
Exposure response analysis has emerged as an important way to predict drug-induced QT effects in patients and have been widely applied to data from TQT studies. More recently, a collaborative initiative was undertaken between industry, the Cardiac Safety Research Consortium and FDA, to prospectively evaluate whether exposure response analysis applied to data from early clinical trials using intense ECG monitoring with a High Precision QT technique can detect the QT effect of a group of known QT prolonging drugs. The objective was to demonstrate that this approach can exclude small QT effects with the same confidence as in TQT studies and thereby serve as a replacement. The IQ-CSRC study was fully successful and has led to the decision by the ICH E14 group to revise the clinical guidance document.
The purpose of this webinar is to share the results of the IQ-CSRC study, discuss best practices for collection of high precision ECG data at the site, discuss what it will take to obtain a waiver for the TQT study and to which extent there is a remaining role for TQT studies.
Dr. Borje Darpo
Chief Scientific Officer, iCardiac Technologies
Borje Darpo is board-certified in cardiology and internal medicine and Associate Professor of Cardiology at the Karolinska Institute since 2000. He has 18 years of industry experience, including senior management positions in small, mid-sized, and large pharma, as well as from a global CRO. He has led or has been responsible for projects in all phases of clinical development, including filing and approval of an NDA. Dr. Darpo’s experience from cardiovascular safety assessment of drugs is broad and includes participation in the generation of existent regulatory guidance on QT assessment (CHMP and ICH E14), previous co-chair of the ILSI/HESI cardiovascular safety subcommittee, previous co-chair of the scientific oversight committee of CSRC, generation of internal company-specific guidance on cardiovascular safety assessment, and numerous reviews of programs both internally and as a consultant. Dr. Darpo has served as the EFPIA deputy topic leader for the ICH E14 Implementation Working Group, which worked with implementation of this guidance and support to Sponsors through a Q&A process. Dr. Darpo is a member of the Scientific Oversight Committee for the Cardiac Safety Research Consortium (CSRC) with participation from FDA, academia, and EU/US industry. Dr. Darpo has co-authored numerous publications on QT assessment, including White Papers on ‘Early QT assessment’ and the IQ-CSRC study validating ECG evaluation in early stage clinical studies.
This webinar is intented for CEO, Chief Medical Officer, Chief Scientific Officer and other senior level executives involved in Early Clinical Development, R&D, Regulatory, and Clinical Operations for Bio/Pharmaceutical companies. This presentation will especially benefit those working in Phase I, Phase II or cardiac safety.
