## Exhibit 99.1

**Exhibit 99.1**

**Replimune Receives Complete Response Letter from FDA for RP1 Biologics License Application<br> for the Treatment of Advanced Melanoma**

WOBURN, Mass., July 22, 2025 (GLOBE NEWSWIRE) -- Replimune Group, Inc. (NASDAQ: REPL), a clinical stage biotechnology company pioneering the development of novel oncolytic immunotherapies, today announced that the U.S. Food and Drug Administration (FDA) has issued a Complete Response Letter (CRL) regarding the Biologics License Application (BLA) for RP1 (vusolimogene oderparepvec) in combination with nivolumab for the treatment of advanced melanoma.

The CRL indicates that the FDA is unable to approve the application in its present form. The FDA has indicated that the IGNYTE trial is not considered to be an adequate and well-controlled clinical investigation that provides substantial evidence of effectiveness. Furthermore, the FDA said the trial cannot be adequately interpreted due to the heterogeneity of the patient population. The CRL also states that there are items related to the confirmatory trial study design which need to be addressed, including contribution of components. Importantly, no safety issues were raised.

The Company will request a Type A meeting and expects it will be granted within 30 days. Replimune plans to urgently interact with the FDA to find a path forward for the timely accelerated approval of RP1 without which the development of RP1 for advanced cancer patients with limited options will not be viable.

"We are surprised by this FDA decision and disappointed for advanced melanoma patients who have limited treatment options as highlighted by the granting of breakthrough status at the time we provided the IGNYTE primary data," said Sushil Patel, Ph.D., Chief Executive Officer, Replimune. "The issues highlighted in the CRL were not raised by the agency during the mid- and late-cycle reviews. Additionally, we had also aligned on the design of the confirmatory study. We strongly believe that RP1 in combination with nivolumab can bring substantial benefit to advanced melanoma patients."

**About RP1**

RP1 (vusolimogene oderparepvec) is Replimune's lead product candidate and is based on a proprietary strain of herpes simplex virus engineered and genetically armed with a fusogenic protein (GALV-GP R-) and GM-CSF, intended to maximize tumor killing potency, the immunogenicity of tumor cell death, and the activation of a systemic anti-tumor immune response.

**About Replimune**

Replimune Group, Inc., headquartered in Woburn, MA, was founded in 2015 with the mission to transform cancer treatment by pioneering the development of novel oncolytic immunotherapies. Replimune's proprietary RPx platform is based on a potent HSV-1 backbone intended to maximize immunogenic cell death and the induction of a systemic anti-tumor immune response. The RPx platform is designed to have a unique dual local and systemic activity consisting of direct selective virus-mediated killing of the tumor resulting in the release of tumor derived antigens and altering of the tumor microenvironment to ignite a strong and durable systemic response. The RPx product candidates are expected to be synergistic with most established and experimental cancer treatment modalities, leading to the versatility to be developed alone or combined with a variety of other treatment options.
