LOS ANGELES, Nov. 19, 2025 (GLOBE NEWSWIRE) -- The Schall Law Firm, a national shareholder rights litigation firm, announces that it is investigating claims on behalf of investors of Alector, Inc. (“Alector” or “the Company”) (NASDAQ: ALEC) for violations of the securities laws.

The investigation focuses on whether the Company issued false and/or misleading statements and/or failed to disclose information pertinent to investors. Alector issued a press release on October 21, 2025, "announc[ing] results from the Phase 3 INFRONT-3 clinical trial evaluating latozinemab (AL001) in individuals with frontotemporal dementia due to a progranulin gene mutation (FTD-GRN)." According to the Company, its drug candidate "did not meet the clinical co-primary endpoint of slowing FTD-GRN progression," and "the secondary and exploratory endpoints, such as fluid biomarkers and volumetric magnetic resonance imaging (vMRI), demonstrated no treatment-related effects on FTD-GRN." Based on this news, shares of Alector fell by almost 50% on the next day.
