Schall, Brown & Schwartz LLP (“SBS”), a national shareholder rights litigation firm, announces that it is investigating claims on behalf of investors of MapLight Therapeutics, Inc. (“MapLight” or “the Company”) (NASDAQ: MPLT) for violations of the securities laws.

INVESTIGATION DETAILS: The investigation focuses on whether the Company issued false and/or misleading statements and/or failed to disclose information pertinent to investors. On July 27, 2026, MapLight shares fell more than 50% in premarket trading after its Phase 2 trial reported mixed results for its schizophrenia drug candidate. According to the Company, “The 330/6 mg once-daily dose, which results in lower daily exposure than BID dosing, demonstrated numerical improvement over placebo, but did not achieve statistical significance on the primary endpoint, MapLight Therapeutics (MPLT) noted.” Based on this news, shares of MapLight opened down 65% on the same day.
