The Allegations: Rosen Law Firm is Investigating the Allegations that MoonLake Immunotherapeutics (NASDAQ: MLTX) Misled Investors Regarding its Business Operations.

According to the complaint, throughout the Class Period, defendants made false and/or misleading statements, as well as failed to disclose material facts, regarding the distinction between the Nanobodies and monoclonal antibodies, including that: (1) SLK and BIMZELX share the same molecular targets (the inflammatory cytokines IL-17A and IL-17F); (2) SLK’s distinct Nanobody structure would not confer a superior clinical benefit over the traditional monoclonal structure of BIMZELX; (3) SLK’s distinct Nanobody structure supposed tissue penetration would not translate to clinical efficacy; and (4) based on the foregoing, defendants lacked a reasonable basis for their positive statements regarding SLK’s purported superiority to monoclonal antibodies. When the true details entered the market, the lawsuit claims that investors suffered damages.
