3D Tumor Model Screens in Clonogenic Assays

In conjunction with our drug sensitivity and molecular characterization data, our 3D Tumor Models, done by using our proprietary patient-derived xenograft (PDX Model) explants or cell line derived xenografts (CDX Models), enable you to evaluate the potency of your compound compared to standard-of-care drugs. This allows you to identify the most promising drug candidates, tumor histotypes and molecular subtypes for further testing.

Charles Rivers ex vivo 3D tumor model can be used to screen cancer therapies in vitro, in a range tumor histotypes.

PDX Models and Combination Studies

Data collected in 3D Tumor Models can then be used to select PDX models for subsequent in vivo efficacy tests. The data can also be used to run systematic two-drug combination therapy studies over a range of concentrations and to correlate the tumor response with molecular data (biomarker identification).
