Revolutionising drug development by making toxicity testing more human
Developing a ready-to-use toxicity analysis based on human cells
Testing new drugs for toxicity is an essential part of the drug development process. Toxicity can have major consequences for people, from skin irritation to cancer.1
Screening drug candidates for toxicity early in the development process is not only important to avoid endangering public health, it can also reduce the need to withdraw drugs further along in the process, such as at clinical trials, which is both costly and wasteful. As many as 30% of drug candidates must be withdrawn at clinical testing or later due to toxicity.2
Conventionally, drug screening has relied on live animals or animal cells and tissues. However, animal models do not always accurately predict human responses because toxicity is species-dependent and the underlying biochemistry is often complex and poorly understood.2
Although technology-based toxicity screenings of humans are available, the cost, workload and expertise required make them too demanding for routine use. A tool that enables testing in human tissue could improve the accuracy of predicting human responses to drugs before they go to clinical trial.
Reproducing human cells quickly and cost-effectively
A ready-to-use toxicity assay (R2U-Tox-Assay) is a test for toxicity using plates that provide a biologically active environment. Within this system, maturated heart and nerve cell models can be quickly and cost-effectively produced from human-induced pluripotent stem cells, or hiPSCs.
The ready-to-use plates undergo cryopreservation, or freezing, and are shipped direct to customers. Freezing reduces any variability during travel. This strict, ready-to-use approach means the end customer can perform screenings with minimal effort. The product is also designed to integrate easily in conventional drug screening workflows of pharmaceutical companies.
EIT Health is helping bring human diversity to the petri dish to improve drug development
EIT Health’s support has a clear focus: to enable inventors to transform innovative ideas in a proof-of-concept state into a market-ready product or service. Innovations like R2U Tox-Assay will not only improve the lives of patients but also help clinicians detect human toxicity much earlier.
Thanks to the EIT Health consortium, the various aspects of the project were able to fuse together. These included the timely and cost-effective expansion of hiPSCs, robust differentiation of high-quality tissue models, and processes and tools to deliver the screening system to customers.
The team behind the screening tool combined translational and market-driven R&D of ready-to-use products. One of the partners, Janssen Pharmaceutical NV, is also interested in using the Tox-Assay as a valuable R&D tool for future drug development.
