The firms will evaluate Stratafide, a pan-solid tumor diagnostic test designed to identify actionable genomic alterations in tissue or blood samples.

While the guidance may lead to more streamlined CDx indications in precision oncology, test developers will still need to generate evidence, perhaps with limited pharma support.

The FDA approved the drug based on data on response rate but continued approval is contingent on the results of a randomized study showing a PFS and OS advantage.

A study of both tissue and blood samples from patients in a small trial found that liquid biopsy may detect putative resistance mutations missed in tissue.

With TMB as a CDx, the drug will be available to more patients as a salvage option, but doctors will still need to consider the complex biomarker amid evolving research.

The agency recognized that having some companion tests approved for a few but not all cancer drugs with the same molecularly defined indication is not optimal for patient care.

Investigators reported on how ctDNA, measured using Natera's patient-specific Signatera assays, corresponded to a patient's disease progression and other biomarkers.

A case series in partnership with My Gene Counsel to highlight the challenges genetics professionals and oncologists are grappling with as genetic testing is increasingly used in patient care.
