Charles River to license PDX lines to InSphero for development of 3D InSight™ PDX Microtissues, expansion of in vitro oncology services.

InSphero AG and Charles River Laboratories International, Inc. today announced a partnership through which Charles River will license its collection of patient-derived xenograft (PDX) tumors to InSphero. Additionally, Charles River will leverage InSphero’s proprietary 3D cell culture technology to further extend and complement its pre-clinical services, using in vitro 3D InSight™ Tumor Microtissues derived from its existing PDX collection.

“Over the past year, we have seen an increased demand from our oncology clients for enhanced speed and efficiency in early drug discovery,” said Birgit Girshick, Corporate Senior Vice President, Global Discovery Services at Charles River. “In vitro discovery platforms offer a strong solution, and our partnership with InSphero significantly bolsters our capabilities in this field.”

In vitro 3D solutions enable the evaluation of a compound’s potency compared to standard-of-care drugs. This in vitrotesting provides for identification of the most promising drug candidates, tumor histotypes and molecular subtypes. Data collected in these tests can then be used to select PDX models for subsequent in vivo efficacy tests. The data can also be used to run systematic combination therapy studies over a range of concentrations and to correlate the tumor response with molecular data.

“Licensing Charles River’s robust library of PDX tumor models significantly expands our current disease model portfolio in diabetes and liver fibrosis” said Jan Lichtenberg, Ph.D., Chief Executive Officer and Co-Founder at InSphero. “The combination of their extensive background in PDX tumors, combined with our proprietary and industry-validated 3D cell culture technology, will help pave the way for future breakthroughs. Expanding our 3D InSight™ Discovery Platform to Charles River’s PDX models will offer scalability, speed and unmet biological relevance in vitro.”
