Class action lawsuit filed over failed cancer trial and alleged nondisclosure of adverse data.

Berger Montague has filed a class action lawsuit against GRAIL, Inc. on behalf of investors who purchased or acquired GRAIL common stock between May 13, 2025 and February 19, 2026. The complaint alleges that the company failed to disclose that its NHS-Galleri trial was insufficient to demonstrate a statistically significant reduction in late-stage cancers and that it withheld adverse trial data. On February 19, 2026, GRAIL revealed the trial did not meet its primary endpoint, causing shares to drop from $101.53 to $50.21, a decline of approximately 50.55% in a single day. Investors have until August 4, 2026 to seek lead plaintiff appointment.
