Release Details

WOBURN, Mass., Aug. 07, 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 first quarter ended June 30, 2025 and provided a business update.

The Company announced on July 22, 2025 that the U.S. Food and Drug Administration (FDA) had issued a Complete Response Letter (CRL) for the RP1 BLA in advanced melanoma.

“Based on the compelling clinical data and safety profile generated to date with RP1 in the IGNYTE study, the melanoma community, including clinical experts and patients, strongly believe RP1 should be made available to patients that have few remaining treatment options as soon as possible. We are committed to finding an expeditious path forward with the FDA,” said Sushil Patel, Ph.D., CEO of Replimune.

Program Highlights & Milestones

RP1 (vusolimogene oderparepvec)

• The global Phase 3 trial, IGNYTE-3 assessing RP1 in combination with nivolumab is ongoing. The trial is expected to enroll approximately 400 patients across 100 sites globally 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. Following the CRL, the Company anticipates discussing the design of this trial with the FDA.
  
  

RP1 (vusolimogene oderparepvec)

• RP1 + nivolumab in non-melanoma skin cancers
  • The Company continues to evaluate the potential of RP1 in merkel cell carcinoma, basal cell carcinoma and angiosarcoma, and locally advanced cutaneous squamous cell carcinoma, including anti-PD1-failed patients, in the ongoing IGNYTE trial cohort.
• RP1 in skin cancer organ transplant patients
  • The Company continues to evaluate RP1 as monotherapy in cutaneous squamous cell carcinoma patients with organ transplants in its Phase 2 ARTACUS trial. Data to-date has shown RP1 to be well tolerated with no cases of RP1-related allograft rejection observed. The overall response rate was 34.6% with a duration of response of 24 months in 61% of patients in the intent-to-treat population. ARTACUS continues to enroll patients.

RP2

• RP2 in uveal melanoma
  • The registration-directed Phase 2/3 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 with data anticipated in the first half of 2026. This 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.
• RP2 in biliary tract cancer (BTC)
  • As previously reported, the Company expects to dose its first patient in the second half of 2025 in a cohort evaluating RP2 in patients with biliary tract cancer. This trial will evaluate RP2 combined with durvalumab and is expected to enroll 30 patients.

Financial Highlights

• Cash Position: As of June 30, 2025, cash, cash equivalents and short-term investments were $403.3 million, as compared to $483.8 million as of fiscal year ended March 31, 2025. The decrease in cash balance was a result of cash burn related to 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 June 30, 2025 will enable the Company to fund operations into the fourth quarter of 2026 which includes 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 $57.8 million for the fiscal first quarter and $43.0 million for the fiscal first quarter ended June 30, 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 medical affairs and consulting costs. Research and development expenses included $4.7 million in stock-based compensation expenses for the fiscal first quarter ended June 30, 2025.
  

• S,G&A Expenses: Selling, general and administrative expenses were $32.6 million for the fiscal first quarter ended June 30, 2025, as compared to $14.4 million for the fiscal first quarter ended June 30, 2024. Selling, general and administrative expenses included $4.1 million in stock-based compensation expenses for the fiscal first quarter ended June 30, 2025.
  
• Net Loss: Net loss was $86.7 million for the fiscal first quarter ended June 30, 2025 and $53.8 million for the fiscal first quarter ended June 30, 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 intended to ignite local 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 then activate 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.
