WOBURN, Mass., May 22, 2025 (GLOBE NEWSWIRE) -- Replimune Group, Inc. (Nasdaq: REPL), a clinical stage biotechnology company pioneering the development of novel oncolytic immunotherapies, today announced financial results for the fiscal fourth quarter and year ended March 31, 2025 and provided a business update.

“As we near our PDUFA date, our commercial organization is now fully hired and ready to execute our first launch in advanced melanoma,” said Sushil Patel, Ph.D., CEO of Replimune. “We have a deep understanding of the market landscape, prescriber adoption and referral patterns, and a launch plan optimized for intra-tumoral delivery across all customer segments. We believe the opportunity for RP1 to help improve the lives of patients with advanced melanoma is significant. We estimate approximately 13,000 patients progress on or after PD-1 treatment annually in the U.S. with approximately 80% of these patients eligible for treatment with RP1. Importantly, these treatments will take place in the outpatient setting and not require hospitalization. We look forward to further discussing our commercial plans for RP1 and pipeline development for RP1 and RP2 at an investor day on June 24th.”

Program Highlights & Milestones

RP1 (vusolimogene oderparepvec)

• RP1 combined with Opdivo^® (nivolumab) in anti-PD1 failed melanoma
  • The FDA recently completed their late-cycle review and manufacturing inspections for the biologics license application, which remains on schedule ahead of a July 22, 2025 PDUFA date.
  • The FDA has indicated no advisory committee is planned.
  • The Company completed the build out of its commercial infrastructure, including the hiring and training of customer-facing teams. Distribution channels have been established and are ready to receive product, pending approval, and key state licensing is in place.
  • Enrollment is ongoing in the confirmatory Phase 3 trial, IGNYTE-3, with over 100 sites planned globally. This trial is expected to enroll 400 patients and is assessing RP1 in combination with nivolumab in patients with advanced melanoma who have progressed on anti-PD-1 and anti-CTLA-4 therapies or are ineligible for anti-CTLA-4 treatment. The primary endpoint of this trial is overall survival and key secondary endpoints are progression free survival and overall response rate.
    
    

RP2

• RP2 in uveal melanoma
  • The registration-directed REVEAL trial of RP2 in metastatic uveal melanoma is currently enrolling. The clinical trial is expected to enroll approximately 280 patients with metastatic uveal melanoma who are immune checkpoint inhibitor-naïve and evaluate RP2 in combination with nivolumab versus ipilimumab in combination with nivolumab. The primary endpoints of the trial are overall survival and progression free survival, and key secondary endpoints are overall response rate and disease control rate.
• RP2 in hepatocellular carcinoma (HCC)
  • The Phase 2 clinical trial of RP2 combined with atezolizumab and bevacizumab in anti-PD1/PD-L1 progressed HCC is currently enrolling. The clinical trial will evaluate RP2 combined with the second-line therapy of atezolizumab and bevacizumab and is expected to enroll 30 patients. The trial is being conducted under a collaboration and supply agreement with Roche.

Upcoming Events

• American Society of Clinical Oncology (ASCO) 2025 Annual Meeting being held May 30-June 3, 2025:

  • Poster: Biosafety analysis from the skin cancer cohorts in the IGNYTE clinical trial of RP1
  • Poster: A randomized, controlled, multicenter, phase 3 study of vusolimogene oderparepvec combined with nivolumab vs. treatment of physician’s choice in patients with advanced melanoma that has progressed on anti-PD-1 and anti-CTLA-4 therapy (IGNYTE-3)
  • Poster: A randomized, phase 2/3 clinical trial investigating RP2 plus nivolumab vs. ipilimumab plus nivolumab in immune checkpoint inhibitor-naïve patients with metastatic uveal melanoma
  • Additional poster from an investigator sponsored trial: A phase 1/2 study of vusolimogene oderparepvec (RP1) in primary melanoma (mel) to reduce the risk of sentinel lymph node (SLN) metastasis.

Financial Highlights

• Cash Position: As of March 31, 2025, cash, cash equivalents and short-term investments were $483.8 million, as compared to $420.7 million as of fiscal year ended March 31, 2024. The increase in cash balance was a result of the public offering in November 2024, somewhat offset by cash utilized in operating activities in advancing the Company’s clinical development plans.
  
  
  
  Based on the current operating plan, the Company believes that existing cash, cash equivalents and short-term investments, as of March 31, 2025 will enable the Company to fund operations into the fourth quarter of 2026 which includes scale up for the potential commercialization of RP1 in skin cancers and for working capital and general corporate purposes and excludes any potential revenue.

• R&D Expenses: Research and development expenses were $54.0 million for the fiscal fourth quarter and $189.4 million for the fiscal year ended March 31, 2025, as compared to $42.6 million for the fiscal fourth quarter and $175.0 million for the fiscal year ended March 31, 2024. This increase was primarily due to an increase in personnel-related costs as we scaled operations in preparation for commercial launch of RP1, as well as consulting and facility-related costs. Research and development expenses included $4.5 million in stock-based compensation expenses for the fiscal fourth quarter and $18.4 million for the fiscal year ended March 31, 2025.
  
  
• S,G&A Expenses: Selling, general and administrative expenses were $25.4 million for the fiscal fourth quarter and $72.2 million for the fiscal year ended March 31, 2025, as compared to $16.2 million for the fiscal fourth quarter and $59.8 million for the fiscal year ended March 31, 2024.

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 RP2

RP2 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. RP2 additionally expresses an anti-CTLA-4 antibody-like molecule, as well as GALV-GP R- and GM-CSF. RP2 is intended to provide targeted and potent delivery of these proteins to the sites of immune response initiation in the tumor and draining lymph nodes, with the goal of focusing systemic-immune-based efficacy on tumors and limiting off-target toxicity.

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.
