Understanding the Class Action Against MoonLake Immunotherapeutics

Investors in MoonLake Immunotherapeutics (NASDAQ: MLTX) should be aware of an ongoing class action that seeks justice for shareholders. Robbins LLP, a law firm well-versed in defending investor rights, has announced the filing of a class action on behalf of those who purchased MLTX shares within a specific timeframe.

Background on MoonLake Immunotherapeutics

MoonLake Immunotherapeutics focuses on developing therapies for inflammatory diseases, particularly those associated with interleukin-17 (IL-17). This Swiss biotechnology firm is currently navigating a challenging legal landscape due to allegations concerning the efficacy claims of its drug candidate, SLK.

Allegations of Misinformation

The crux of the class action revolves around allegations that MoonLake misled investors about SLK’s performance compared to existing treatments. The complaint points out several critical assertions: firstly, SLK and BIMZELX—an FDA-approved drug for similar conditions—target the same inflammatory cytokines, IL-17A and IL-17F. Secondly, the claims that SLK’s unique Nanobody structure would guarantee better clinical outcomes over BIMZELX have been called into question.

Key Events Leading to the Class Action

A significant turning point occurred on September 28, 2025, when MoonLake released week-16 results from its Phase 3 VELA program. Contrary to optimistic projections, these results indicated that SLK did not perform competitively against BIMZELX, leading to a drastic reduction in share price. Following this disappointing announcement, MLTX shares plummeted by nearly 90%, reinforcing the severity of the allegations against the firm.

What Investors Can Do

If you are a shareholder of MoonLake Immunotherapeutics, you may have the opportunity to participate in the class action. Interested investors wishing to take an active role as lead plaintiffs must submit their documents by December 15, 2025. It's important to note that participation in litigation is not mandatory for recovery and shareholders can choose to remain passive members of the class.
