Replimune Group, Inc. Class Action Lawsuit: What Investors Need to Know

Replimune Group, Inc. Class Action Lawsuit Overview

Investors who have suffered considerable losses from their investments in Replimune Group, Inc. (NASDAQ: REPL) between November 22, 2024, and July 21, 2025, are being reminded of a class action lawsuit initiated on their behalf by Robbins LLP. This clinical-stage biotechnology firm specializes in developing treatments known as oncolytic immunotherapies aimed at combating cancer.

Details of the Case

The allegations underpinning this class action lawsuit stem from claims that Replimune misrepresented the effectiveness of its IGNYTE trial, which is critical for regulatory approval of its treatments. During the class period, the defendants apparently failed to disclose significant issues that raised doubts about the trial's validity, which, according to the complaint, led the FDA to determine that the trial was inadequate.

On July 22, 2025, Replimune announced that it had received a complete response letter (CRL) from the FDA concerning its RPI Biologics License Application for treating advanced melanoma. This letter indicated that the trial did not meet the requirements for substantial proof of effectiveness, significantly affecting the company's stock price, which plummeted by over 77% in just one day, leading to a severe loss for its investors.

What Should Investors Do?

Affected shareholders are encouraged to consider becoming involved in the class action. Those who wish to serve as lead plaintiffs must file their applications with the court by September 22, 2025. Taking on this role means representing the interests of fellow shareholders in guiding the legal action, although it's important to note that participation is not obligatory to potentially recover any losses.

Robbins LLP works on a contingency fee basis, meaning investors incur no fees or expenses unless a recovery is achieved. This risk-free representation is a fundamental aspect of their commitment to shareholder rights.

As part of their outreach, Robbins LLP has advocated for greater corporate accountability and improved governance standards since 2002.
