Engineered 2D & 3D hiPSC-CM platforms to detect cardiovascular safety liabilities

Safety evaluation of drugs is a costly, protracted process that requires ~500,000 procedures on rodents, rabbits, dogs and primates in the UK annually. Human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) could provide faster, more accurate safety testing, reducing costs and sparing thousands of animals. Because hiPSC-CM are in development, improvements are needed to integrate mature cells into platform(s) that simultaneously report on electrophysiology, calcium and contractility under (patho)physiological load.

Our unique international consortium comprises academic/SME partners with >50 person-years of expertise with stem cell-derived cardiomyocytes.

Through effective management, sponsor interaction and an established collaborative network, Phase 2 will further develop 2D, pseudo-3D and 3D platforms using cost-effective hiPSC-CM produced in-house. Cell function will be improved via advanced media, flexible substrates and cell mixing. Researcher mobility will facilitate exchange of skills in cell engineering, hardware/software design, readouts and analysis, while in-kind contributions of compounds and data from the sponsor will enhance validation. We will offer a globally-competitive portfolio of screening platforms. Our ready-made consortium will be primed for entry into EU schemes (Horizon2020, IMIs). It will bolster existing 3Rs activity that has recently won Dutch (Hugo van Poelgeest; Lef in het Lab) and German (DFG Ursula Händel Tierschutzpreis) animal reduction prizes.
