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.
