SAN DIEGO, July 21, 2025 (GLOBE NEWSWIRE) -- Robbins LLP informs stockholders that a class action was filed on behalf of investors who purchased or otherwise acquired (a) Alto Neuroscience, Inc. (NYSE: ANRO) common stock pursuant and/or traceable to the Offering Documents issued in connection with the Company’s initial public offering ("IPO") conducted on or about February 2, 2024, and/or (b) Alto securities between February 2, 2024 and October 22, 2024. Alto operates as a clinical-stage biopharmaceutical company in the U.S. The Company’s product pipeline includes, inter alia, ALTO-100, which at the time of the IPO was in a Phase 2b clinical trial for the treatment of patients with major depressive disorder (“MDD”).

The Allegations: Robbins LLP is Investigating Allegations that Alto Neuroscience, Inc. (ANRO) Misled Investors Regarding the Viability of its Drug Candidate

According to the complaint, the Offering Documents in support of the IPO were negligently prepared. Additionally, during the class period, defendants failed to disclose that: (i) ALTO-100 was less effective in treating MDD than defendants had led investors to believe; (ii) accordingly, ALTO-100’s clinical, regulatory, and commercial prospects were overstated; and (iii) as a result, Alto’s business and/or financial prospects were overstated.

On October 22, 2024, Alto issued a press release announcing topline results from the Phase 2b trial evaluating ALTO-100 as a treatment for MDD. That press release stated, in relevant part, that “ALTO-100 in patients with [MDD] did not meet its primary endpoint, assessed by a change from baseline in Montgomery-Åsberg Depression Rating Scale (MADRS), compared to placebo.” On this news, Alto’s stock price fell $10.17 per share, or 69.99%, to close at $4.36 per share on October 23, 2024.
