Journal ArticleDOI
Results from the IQ-CSRC prospective study support replacement of the thorough QT study by QT assessment in the early clinical phase.
Borje Darpo,Charles Benson,Corina Dota,Georg Ferber,Christine Garnett,Cynthia L. Green,Venkateswar Jarugula,Lars Johannesen,James Keirns,Kevin Krudys,Jiang Liu,Catherine Ortemann-Renon,Steve Riley,N Sarapa,B Smith,RR Stoltz,Meijian Zhou,Norman Stockbridge +17 more
TL;DR: There is evidence that robust QT assessment in early‐phase clinical studies can replace the thorough QT study, and exposure–response analysis can detect QT effects in a small study with healthy subjects.
Journal ArticleDOI
Scientific white paper on concentration-QTc modeling
Christine Garnett,Peter L. Bonate,Qianyu Dang,Georg Ferber,Dalong Huang,Jiang Liu,Devan V. Mehrotra,Steve Riley,Philip T. Sager,Christoffer W. Tornøe,Yaning Wang +10 more
TL;DR: Recommendations are provided on how to plan and conduct a definitive QTc assessment of a drug using C-QTc modeling in early phase clinical pharmacology and thorough QT studies and topics include important study design features in a phase 1 study.
Journal ArticleDOI
Mechanism of Action and Clinical Application of Tafamidis in Hereditary Transthyretin Amyloidosis
Teresa Coelho,Giampaolo Merlini,Christine Bulawa,James Fleming,Daniel P. Judge,Jeffery W. Kelly,Mathew S. Maurer,Violaine Planté-Bordeneuve,Richard Labaudinière,Rajiv Mundayat,Steve Riley,Ilise Lombardo,Pedro E. Huertas +12 more
TL;DR: Tafamidis meglumine is a rationally designed, non-NSAID benzoxazole derivative that binds with high affinity and selectivity to TTR and kinetically stabilizes the tetramer, slowing monomer formation, misfolding, and amyloidogenesis.
Journal ArticleDOI
The IQ‐CSRC Prospective Clinical Phase 1 Study: “Can Early QT Assessment Using Exposure Response Analysis Replace the Thorough QT Study?”
Borje Darpo,Nenad Sarapa,Christine Garnett,Charles Benson,Corina Dota,Georg Ferber,Venkateswar Jarugula,Lars Johannesen,Lars Johannesen,James Keirns,Kevin Krudys,Catherine Ortemann-Renon,Steve Riley,Danise Rogers-Subramaniam,Norman Stockbridge +14 more
TL;DR: A clinical study in healthy subjects demonstrating that the thorough QT (TQT) study can be replaced by robust ECG monitoring and exposure–response analysis of data generated from First‐in‐Man single ascending dose (SAD) studies is designed.
Journal ArticleDOI
Cardiac Safety Research Consortium: Can the thorough QT/QTc study be replaced by early QT assessment in routine clinical pharmacology studies? Scientific update and a research proposal for a path forward
Borje Darpo,Borje Darpo,Christine Garnett,Charles Benson,James Keirns,Derek J. Leishman,Marek Malik,Nitin Mehrotra,Krishna Prasad,Steve Riley,Ignacio Rodriguez,Philip T. Sager,Nenad Sarapa,Robert Wallis +13 more
TL;DR: A group of experts convened to discuss how to improve the confidence in QT data from early clinical studies, for example, the First-Time-in-Human trial, through collection of serial electrocardiograms and pharmacokinetic samples and the use of exposure response analysis.
