The Health Policy War Room

The FDA recently granted authorization for the first multi-gene test for assessing hereditary cancer risk, marking a significant advancement in genetic screening capabilities. Developed by Invitae Corporation, the Invitae Common Hereditary Cancers Panel analyzes variants in 47 genes associated with increased cancer risk. Using next-generation sequencing on DNA from blood samples, the test looks at BRCA1 and BRCA2 variants linked to breast and ovarian cancer, as well as other cancer-related genes.  (image source: Adobe Stock Images) The FDA’s approval provides a regulatory framework giving labs a clearer roadmap for developing similar multi-gene panels. With an authorized model in place, labs can proceed more confidently in navigating FDA submissions. Specifically, the de novo classification created for Invitae’s test allows future lab-developed panels to gain regulatory clearance through the expedited 510(k) pathway by demonstrating substantial equivalence. This streamlined validat...

Liquid biopsies are poised to disrupt cancer testing as we know it. These novel blood tests analyze circulating tumor DNA (ctDNA) and other molecules released by cancer cells, providing a non-invasive option for detection, diagnosis, and monitoring. The promise of liquid biopsies has generated tremendous excitement, along with over $1 billion in investments and acquisitions in recent years. But how close are we to realizing their full potential?  A recent review article sounds a note of caution amidst the hype. While liquid biopsies show ability to detect cancer, evidence that they improve patient outcomes is still lacking. Randomized trials with survival endpoints are needed to prove clinical utility. However, this provides the perfect opportunity for innovative diagnostics companies. Rather than dampening enthusiasm, these evidence gaps highlight major growth possibilities if companies can demonstrate real-world value.   We envision liquid biopsies transforming oncology...
