An FDA advisory panel voted in favor of GRAIL's Galleri multi-cancer early detection test on September 23. The Molecular and Clinical Genetics Devices Panel went 10 to 0 that the test is safe, 6 to 4 that it is effective, and 7 to 2 with one abstention that its benefits outweigh its risks.
GRAIL filed the PMA on January 29, 2026. It asks for approval to screen adults aged 50 and older for multiple cancers from a single blood draw. The company pointed the panel to PATHFINDER 2 in North America and the NHS-Galleri trial in England, and said Galleri has detected roughly four to seven times more cancers than standard of care alone, most of them at earlier stages.
The effectiveness split is the number to watch. FDA is not bound by panel votes, and four dissents on the central question leave reviewers room to attach postmarket conditions or narrow the indication. A decision is expected in the coming months.
