CASE ALLEGATIONS: Replimune is a clinical-stage biotechnology company focused on developing and commercializing oncolytic immunotherapies to treat cancer. Replimune’s lead product candidate is RP1 (vusolimogene oderparepvec), according to the complaint.
The Replimune class action lawsuit alleges that defendants made false and/or misleading statements and failed to disclose that they recklessly overstated the prospects of Replimune’s IGNYTE trial despite material issues that they knew or should have known, which ultimately led the U.S. Food and Drug Administration (“FDA”) to determine that the IGNYTE trial was inadequate and not well-controlled.
The complaint further alleges that on July 22, 2025, Replimune disclosed that the FDA had issued a Complete Response Letter (“CRL”) regarding the Biologics License Application (“BLA”) for RP1, stating it was “unable to approve the application in its present form” and finding that “the IGNYTE trial is not considered to be an adequate and well-controlled clinical investigation that provides substantial evidence of effectiveness.” On this news, the price of Replimune stock fell more than 77%.
