Personalized patient-derived xenografts (pPDX) are increasingly used as tools for drug development in pre-clinical settings, and have been shown to recapitulate the histology and behavior of the cancers from which they are derived. Although, they have been commonly used productively as pre-clinical disease models to study disease biology and drug response, they have not been used prospectively to inform clinical management. pPDX have been employed to inform clinical decision-making in small studies, which have shown high concordance between individual pPDX and patient responses to therapy. While encouraging, the role of this approach in breast, colorectal, ovarian, and other cancer populations and in the context of genomic drug matching strategies remains undefined. This has created an opportunity to evaluate the utility of pPDX as clinical predictors to direct the use of chemo- and targeted therapies in combination with comprehensive genomic and epigenetic analysis for patients with TNBC, CRC, HGSOC and other selected tumor types.
