WOBURN, Mass., May 16, 2024 (GLOBE NEWSWIRE) -- Replimune Group, Inc. (Nasdaq: REPL), a clinical stage biotechnology company pioneering the development of a novel class of oncolytic immunotherapies, today announced financial results for the fiscal fourth quarter and year ended March 31, 2024 and provided a business update.

“We have exciting milestones in the coming months, including sharing the investigator-assessed 12-month IGNYTE data at ASCO and then the official primary analysis by independent central review later in the second quarter,” said Sushil Patel, Ph.D., CEO of Replimune. “Importantly, the design of our Phase 3 confirmatory IGNYTE-3 clinical trial has been agreed with the FDA, with patient enrollment planned to initiate in the second half of the year prior to the submission of our BLA for RP1. We also completed a successful Type C meeting with the FDA to align on our CMC plans ahead of the intended BLA. These are all critical steps as we plan for our next phase as a commercial stage company and, pending FDA approval, prepare to bring our first oncolytic immunotherapy to patients with advanced skin cancer.”

Program Highlights & Milestones

RP1

• RP1 combined with Opdivo^® (nivolumab) in anti-PD1 failed melanoma
  • The Company presented positive six-month follow up data by investigator assessment (N=140) from the anti-PD1 failed melanoma cohort of the IGNYTE clinical trial late last year. The Company is on track to present the 12-month primary analysis by independent central review in Q2 2024.
  • The Company plans to enroll its first patient in the Phase 3 confirmatory IGNYTE-3 trial prior to submitting the RP1 BLA. The Phase 3 trial design has been agreed to with the FDA and will be a 2-arm randomized trial with a defined list of physician’s choice treatment options as the comparator arm in advanced melanoma patients who progressed on anti-PD1 and anti-CTLA-4 therapy or are ineligible for anti-CTLA-4 treatment.
    
    
• RP1 in solid organ transplant recipients with skin cancers
  
  • The Company presented data from the ARTACUS clinical trial of RP1 monotherapy in solid organ transplant recipients with skin cancers at the American Association of Cancer Research (AACR) 2024 Annual Meeting in April 2024. The data included 23 evaluable patients with CSCC (n=20) and MCC (n=3).
  • The data demonstrated an overall response rate (ORR) of 34.8% (8 of 23 evaluable patients, including 5 complete responses and 3 partial responses).
  • RP1 monotherapy was well tolerated, and the safety profile was similar to non-immunocompromised patients with advanced skin cancers (i.e. from the IGNYTE study). No immune-mediated adverse events or evidence of allograft rejection were observed.
  • The ARTACUS clinical trial continues to enroll patients.

• RP1 in combination with Libtayo^® (cemiplimab-rwlc) in CSCC
  
  • The CERPASS trial continues as planned to assess the time-based endpoints of duration of response, progression free survival and overall survival with greater maturity.

RP2

• RP2 in Uveal Melanoma
  • The protocol for the registration-directed clinical trial of RP2 combined with nivolumab in advanced uveal melanoma is near final following input from the FDA.

• RP2 in Hepatocellular Carcinoma (HCC)
  • The Phase 2 clinical trial with RP2 in anti-PD1/PD-L1 progressed HCC of RP2 combined with atezolizumab and bevacizumab is expected to initiate in 2H 2024.

Financial Highlights

• Cash Position: As of March 31, 2024, cash, cash equivalents and short-term investments were $420.7 million, as compared to $583.4 million as of fiscal year March 31, 2023. The decrease was primarily related to 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, 2024 will enable the Company to fund operations into the second half of 2026.

• Debt: As of March 31, 2024, the debt (net of discount) balance was $44.8 million, as compared to $28.6 million as of March 31, 2023. The increase was primarily related to the draw down of $15 million in December 2023, at the time of the closing of the second amendment to the loan and security agreement with Hercules.

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 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 a novel portfolio of 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.
