Companion Diagnostic Strategies for Commercial Success - Andrew Crenshaw
Andrew Crenshaw is the Global CDx Discipline Director at Q2 Solutions. In this episode, he describes strategies for mitigating risk in the development of companion diagnostics (CDx) for immuno-oncology.
Depending on the bio-marker, there might be difficulties in developing an assay that correctly characterizes that bio-marker. There are also, there could be reduced ability to enter into markets due to the accessibility of that particular technology used to identify that bio-marker or test that bio-marker globally. For example, it's common throughout hospitals to have IHC or pathology review of particular of bio-markers but next-gen sequencing is a new and more expensive type of technology, so they might not be able to go after that as a particular companion diagnostic.
But, that being said, the trade-off or what they gain from getting a companion diagnostic, they have a greater chance of reaching the correct population of patients that will see the greatest benefit of their therapeutic.
Andrew discusses an alternative to the traditional three-way partnership of a drug developer, an IVD manufacturer and a CRO. Single-site, pre-market approval can reduce the front-loaded investment needed for an IVD. It also can align better for the management of the project timeline.
