- Class Action Reminder: The Schall Law Firm alerts investors of a class action lawsuit against MoonLake Immunotherapeutics for violations of securities laws related to trades made between March 10, 2024, and September 29, 2025, urging affected investors to contact them by December 15, 2025, to participate.
- Drug Trial Failure: MoonLake's announcement of disastrous Phase 3 trial results for its drug candidate sonelokimab led to a nearly 90% drop in share value, highlighting the company's misleading claims of superiority over other monoclonal antibodies.
- Market Misleading: The company's public statements throughout the class period were deemed false and materially misleading, resulting in significant investor losses and indicating a severe lack of transparency in drug development.
- Legal Consequences: Until the class action is certified, investors are not represented by an attorney, and those who choose not to act may remain absent class members, potentially forfeiting their right to recover losses.

STAT reports that the FDA plans to shift toward requiring only one pivotal trial for approval rather than the traditional two, though details and timing remain unclear pending formal agency communication, Cantor Fitzgerald analyst Prakhar Agrawal tells investors in a research note. While the policy could have broad sector implications, it meaningfully boosts the likelihood of MoonLake's sonelokimab securing hidradenitis suppurativa approval based on a single positive pivotal study, the analyst says. Cantor has an Overweight rating on MoonLake shares.
