Accelerate Cancer Immunotherapy Drug Discovery & Development with Fast and Clinically-Relevant Assays


Immuno-Oncology (IO) is a class of treatment modality designed to boost the body’s natural immune defense against cancer. The IO space is currently dominated by therapeutics development programs targeting immune checkpoint modulators as these molecules hold significant promise in cancer therapy. Another key modality is modulation of Fc-mediated effector mechanisms of therapeutics antibodies including ADCC, ADCP, and CDC.

Eurofins DiscoverX offers the most comprehensive portfolio of cell lines to enable fast, effective, and clinically-relevant understanding of IO to interrogate targets, pathways, and mechanisms to empower quicker development of IO therapeutics. Ready-to-use qualified bioassays have been developed to meet the industry requirements and regulatory expectations for fast and seamless implementation for potency testing in QC lot release of for IO drugs.

Learn how you can rapidly screen and develop antibodies, small molecules, or cellular therapies such as chimeric antigen receptor T cells (CAR-T) for your IO drug discovery and development program.
