Replimune Group Faces Class Action Lawsuit Following FDA Response on License Application

Class Action Lawsuit Against Replimune Group, Inc.

On July 27, 2025, Pomerantz LLP announced a significant legal action against Replimune Group, Inc. (NASDAQ: REPL), revealing that a class action lawsuit has been initiated for investors who experienced monetary losses due to alleged securities fraud. This legal move invites all affected parties to consider their next steps, especially with a critical deadline approaching on September 22, 2025, for designating a Lead Plaintiff. The lawsuit primarily revolves around claims that Replimune, along with certain executives, may have engaged in misconduct, potentially misleading investors about the company's operations and viability.

Background on Replimune’s Recent Challenges

This recent lawsuit comes in the wake of a press release from Replimune dated July 22, 2025, where the company disclosed that the U.S. Food and Drug Administration (FDA) rejected their Biologics License Application (BLA) for RP1, a treatment aimed at advanced melanoma. The FDA issued a Complete Response Letter (CRL), stating the agency could not approve the application in its current state due to inadequacies in the supporting clinical trials. According to the FDA, the IGNYTE trial, which was central to their approval process, did not meet necessary standards for a well-controlled clinical investigation. This entirely disappointing response from the FDA highlighted several concerns about trial design and the heterogeneity of the patient population involved, although it noted no safety issues related to the drug.

Following this announcement, Replimune's stock took a significant hit, plummeting $9.52, or 77.24%, to close at $2.81 per share. Investors reacted strongly to the news, underscoring the volatility and sensitivity surrounding healthcare stocks, particularly those reliant on regulatory approval.
