On August 25, 2025, Pomerantz LLP announced the initiation of a class action lawsuit against Replimune Group, Inc. (NASDAQ: REPL). This legal action highlights serious concerns surrounding the company's business practices and its subsequent impact on investors who faced significant losses.

The class action specifically probes whether Replimune and its executives engaged in securities fraud or other unlawful activities that misled investors. Individuals who bought or acquired Replimune securities during the class period have until September 22, 2025, to seek appointment as Lead Plaintiff by the court.

The Background Context

The basis for this legal action stems from recent troubling developments related to Replimune's product, RV1 (vusolimogene oderparepvec), intended for the treatment of advanced melanoma. On July 22, 2025, the U.S. Food and Drug Administration (FDA) issued a Complete Response Letter (CRL) to Replimune regarding its Biologics License Application (BLA). The letter indicated that there were insufficient grounds for approval based on the current application.

According to the FDA, the data from the IGNYTE trial, which is critical for evaluating the drug's efficacy, was deemed inadequate. Specifically, the trial's results cannot be interpreted decisively due to the lack of homogeneity in the patient population, and the FDA identified aspects of the trial's design that need further clarification and detailing.

Moreover, the FDA confirmed that no safety issues were associated with RV1, which has helped allay some concerns regarding the medication's overall viability.

Impact on Stock Price

Following the FDA's announcement, Replimune's stock took a significant hit, dropping $9.52 per share and closing at $2.81 on the same day, marking a staggering decline of 77.24%. This drastic fall has fueled investor concerns and subsequently led to the filing of the class action lawsuit.
