Aug 7 (Reuters) – Grail said on Friday the U.S. FDA plans to ​hold a meeting ‌of outside experts to review its multi-cancer screening test Galleri in September, sending its ‌shares ​up 4% in ⁠morning trade.

The panel ⁠will review Grail’s request for premarket approval, the Food and Drug Administration’s ​most stringent review process for medical devices. ⁠The agency is ⁠not required to ​follow the panel’s recommendation.

The review ​follows disappointing results for Galleri ‌earlier this year from a three-year UK trial, which found it ⁠did not significantly boost early cancer detection or reduce late-stage diagnoses.

Galleri ⁠is ‌a blood-based cancer ⁠screening test that ​aims ‌to detect signals of ​more than ⁠50 cancers from a single blood sample.
