GRAIL Highlights Galleri Test Growth, Shares NHS-Galleri Trial Results

Biotech firm reports Q4 2025 earnings and provides updates on multi-cancer early detection blood test development and regulatory progress.

Published on Feb. 27, 2026

GRAIL, the biotech company behind the Galleri multi-cancer early detection (MCED) blood test, reported its Q4 2025 earnings and provided updates on the Galleri test's commercial growth, top-line results from the randomized NHS-Galleri trial in the U.K., and progress toward FDA premarket approval.

Why it matters

GRAIL's Galleri test represents a significant advancement in cancer screening, with the potential to detect more than 50 types of cancer at their earliest stages through a simple blood draw. The NHS-Galleri trial results and FDA approval process will be closely watched as indicators of the test's real-world performance and clinical utility.

The details

GRAIL reported that the NHS-Galleri trial did not meet its primary endpoint of a statistically significant reduction in combined Stage III and Stage IV cancers, though the company described a favorable trend after the prevalent screening round. No serious safety concerns were reported among the approximately 70,000 participants who received the Galleri test. GRAIL plans to submit the detailed NHS-Galleri results for presentation at ASCO in late May and extend data collection to reevaluate the impact with more mature data. The company also disclosed full results from the PATHFINDER 2 study, which were consistent with previously presented data. GRAIL completed the final module of its premarket approval (PMA) application to the FDA for Galleri at the end of January, and the company anticipates a 12-month review period.
