Human induced pluripotent stem cell (hiPSC) derived models are heavily explored as alternatives for animal models used in preclinical discovery and safety assessment. Here, Jean-Pierre Valentin from UCB Biopharma will provide a retrospective review on three compounds which showed preclinical and clinical cardiac liabilities. To understand to what extend hiPSC-derived cardiomyocytes could have predicted their side effects, the three compounds were tested using Ncardia’s human iPSC-derived cardiomyocytes in combination with ACEA’s xCELLigence Cardio ECR system. The hiPSC-derived models demonstrated value in refining the integrated cardiac safety assessment.
Using real-time kinetic analysis, this physiologically-relevant human cardiac model allows for the detection of both acute as well as chronic drug-induced toxicities. In the last few years, this predictive validity of hiPSC-derived cardimyocytes has also been substantiated by various case studies and publications. As a result, pharma are slowly integrating these assays into their early safety assessment to detect potential safety hazards and improve compound selection prior to entering the costly and time-consuming animal studies.

Senior Director, Head of Investigative Toxicology
UCB Biopharma SPRL
Jean-Pierre holds a Ph.D. in Physiology & Pharmacology 1990, from the University of Montpellier, France. Following a post-doc at UCSF, Jean-Pierre joined the Pierre Fabre Research Centre (1992-98) where he contributed to the discovery and progression into development of 3 candidate drugs. He joined AstraZeneca to build from inception, develop and lead the Department of Safety Pharmacology where he contributed to the safety evaluation of ~200 candidate drugs across a wide range of therapy areas, leading to the development and successful registration of several marketed products. In February 2014, he joined UCB-Biopharma as Senior Director Head of Investigative Toxicology, based in Belgium. He is a member of several scientific societies; Past President of the Safety Pharmacology Society; co-chair of the HESI subcommittee on QT/Arrhythmia, and the ABPI-NC3Rs-Animal Model Framework. He is involved in training and education programs and is author/co-author of several patents and >180 peer review publications and book chapters.
