FDA guidline on Companion Diagnostics
  • A companion diagnostic is a medical device, often an in vitro device, which provides information that is essential for the safe and effective use of a corresponding drug or biological product. The test helps a health care professional determine whether a particular therapeutic product’s benefits to patients will outweigh any potential serious side effects or risks.

New FDA guidance on laboratory developed test: “Anticipated Details of the Draft Guidance for Industry, Food and Drug Administration Staff, and Clinical Laboratories: Framework for Regulatory Oversight of Laboratory Developed Tests (LDTs)”

  • In light of expanded medical utility and increased patient risk, in addition to increased technologic complexity, the FDA is embarking on a path of increased LDT regulation industry.
  • This regulatory framework will be phased in over the next decade, and a central feature will be the regulatory stratification of LDTs based on patient risk.

Current prognostics tests (excluding PraediCare Dx) for AML fall far short of clinical utility: “Resistance Prediction in AML”. Roland Walter. Leukemia, 2014.
  • The AUC of a bootstrap-corrected multivariable model predicting this outcome was only 0.78, indicating only fair predictive ability. Removal of FLT3-ITD and NPM1 information only slightly decreased the AUC (0.76). Prediction of resistance, defined as primary refractoriness or short relapse-free survival, was even more difficult.
