GemPharmatech has successfully developed multiple PDX models, which cover cancers such as gastrointestinal, liver, pancreatic, lung, and hematologic, for a wide variety of uses, including efficacy evaluations, clinical studies as treatment control, and pathogenesis studies. While conducting efficacy evaluations of immunomodulators like hPD-1/hPD-L1 and hCTLA4 antibodies, the company utilized mouse models with humanized immune systems prepared from PBMCs and HSCs by PDX and CDX techniques. Mouse models with humanized immune checkpoints require no reconstruction of the immune system; therefore, using such models in the preclinical evaluation of the immunomodulators is both more economical and more convenient.
They are capable of monitoring tumor volume and weight and providing a basis for research in hematology, clinical biochemistry, immunohistochemistry, and others.
