O-PDX testing is a drug efficacy study performed on your tumor tissue in live mouse avatars. It’s what scientists call a “functional assay.” Functional assays are systematic in vivo (in-life or in-animal) experiments used to study complex biological processes.
There are many new and emerging technologies in the field of precision oncology (genomic profiling, in silico modeling and others) that can give insight into what therapies might fight your cancer. In fact, these tools are complimentary to O-PDX pharmacology testing because they can help determine which therapies we should test in your study. But none (that we know of) provide the level of certainty possible with O-PDX pharmacology testing.
