Completed enrollment in the CERPASS registration-directed clinical trial evaluating RP1 in cutaneous squamous cell carcinoma (CSCC); primary analysis data expected to be released in H1 2023

Six-month follow-up data from the first 75 patients enrolled in the IGNYTE clinical trial cohort of RP1 combined with Opdivo^® (nivolumab) in anti-PD1 failed melanoma expected by year end

An update on the RP2/3 development program remains on track to be provided by year end

Completed $200 million term-loan that extended cash runway into 2025

WOBURN, Mass., Nov. 03, 2022 (GLOBE NEWSWIRE) -- Replimune Group, Inc. (NASDAQ: REPL), a clinical stage biotechnology company pioneering the development of a novel class of tumor-directed oncolytic immunotherapies, today announced financial results for the fiscal second quarter ended September 30, 2022 and provided a business update.

“We continue working towards establishing our oncolytic immunotherapies as the cornerstone treatment for a variety of solid tumor indications,” said Philip Astley-Sparke CEO of Replimune. “We plan to establish a major skin cancer franchise with our lead program, RP1 and are on track to announce primary data from the CERPASS clinical trial in CSCC in the first half of 2023. Additionally, we look forward to announcing initial data from the IGNYTE clinical trial cohort evaluating RP1 combined with Opdivo in anti-PD1 failed melanoma later this year. As we continue advancing the rest of our pipeline, we are pleased to report that we also remain on track to provide an update on the RP2/3 program, targeted at treating a number of difficult-to-treat cancers, later this year. With a strong financial position enhanced by our recently announced term loan, we have extended our cash runway into 2025 to fund key value-driving catalysts, including the costs of funding commercial infrastructure and running a confirmatory clinical trial to support potentially filing for FDA approval in anti-PD1 failed melanoma under the accelerated approval pathway.”

Corporate Updates

• Extended cash runway into 2025. The Company completed a $200 million non-dilutive debt financing with Hercules Capital, Inc. The financing extends the Company’s cash runway into 2025 ahead of key catalysts from its registration-directed CERPASS and IGNYTE clinical trials in cutaneous squamous cell carcinoma (CSCC) and anti-PD1 failed melanoma, inclusive of the costs of funding commercial infrastructure and running a confirmatory clinical trial to support a potential filing for FDA approval in anti-PD1 failed melanoma under the accelerated approval pathway.

Financial Highlights

• Cash Position:  As of September 30, 2022, cash, cash equivalents and short-term investments were $371.8 million, as compared to $395.7 million as of fiscal year end March 31, 2022. Cash utilized in operating activities in advancing the Company’s expanded clinical development plan was offset by $37.5 million year-to-date in net proceeds generated from the sale of common stock under the Company’s at-the-market facility.
  
  
  
  Based on the current operating plan, the Company believes that existing cash, cash equivalents and short-term investments, as of September 30, 2022, together with unrestricted proceeds available to be drawn under the Hercules debt facility, will enable us to fund our operations into calendar 2025, inclusive of the costs of funding commercial infrastructure and running a confirmatory clinical trial to support a potential filing for FDA approval in anti-PD1 failed melanoma under the accelerated approval pathway.

• R&D Expenses: Research and development expenses were $28.8 million for the second quarter ended September 30, 2022, as compared to $19.9 million for the second quarter ended September 30, 2021. This increase was primarily due to increased clinical and manufacturing expenses driven by the Company’s lead programs and increased personnel expenses. Research and development expenses included $2.5 million in stock-based compensation expenses for the second quarter ended September 30, 2022.

• S,G&A Expenses: Selling, general and administrative expenses were $12.7 million for the second quarter ended September 30, 2022, as compared to $9.3 million for the second quarter ended September 30, 2021.

About CERPASS

CERPASS is Replimune’s registration-directed randomized, global Phase 2 clinical study to compare the effects of Libtayo^® (cemiplimab-rwlc) alone versus a combination of Libtayo and Replimune’s investigational oncolytic immunotherapy RP1. The clinical trial recently completed enrollment and enrolled 211 patients with locally advanced or metastatic cutaneous squamous cell carcinoma (CSCC) who are naïve to anti-PD-1 therapy. The clinical trial will evaluate complete response (CR) rate and overall response rate (ORR) as its two independent primary efficacy endpoints as assessed by independent review, as well as secondary endpoints including duration of response, progression-free survival (PFS), and overall survival (OS). The study is being conducted under a clinical trial collaboration agreement with Regeneron and full commercial rights retained by Replimune. Libtayo is being jointly developed by Regeneron and Sanofi. Libtayo is a registered trademark of Regeneron.

About IGNYTE

IGNYTE is Replimune’s multi-cohort Phase 1/2 trial of RP1 plus Opdivo^® (nivolumab). There are 4 tumor specific cohorts currently enrolling in this clinical trial including a 125-patient cohort in anti-PD-1 failed cutaneous melanoma with registrational intent. This cohort was initiated after completing enrollment in a prior Phase 2 cohort in the same clinical trial of approximately 30 patients with melanoma. The additional cohorts are in non-melanoma skin cancers which includes both naïve and anti-PD-1 failed CSCC, in anti-PD1 failed microsatellite instability high, or MSI-H/dMMR tumors and anti-PD(L)-1 failed non-small cell lung cancer, or NSCLC. This trial is being conducted under a collaboration and supply agreement with Bristol-Myers Squibb Company. Opdivo is a registered trademark of Bristol-Myers Squibb Company.

About RP1

RP1 is Replimune’s lead product candidate and is based on a proprietary new strain of herpes simplex virus engineered and genetically armed to maximize tumor killing potency, the immunogenicity of tumor cell death, and the activation of a systemic anti-tumor immune response.

About RP2 & RP3

RP2 and RP3 are derivatives of RP1 that express additional immune-activating proteins. RP2 expresses an anti-CTLA-4 antibody-like molecule and RP3 additionally expresses the immune co-stimulatory pathway activating proteins CD40L and 4-1BBL. RP2 and RP3 are 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 tumor-directed oncolytic immunotherapies. Replimune’s proprietary RPx platform is based on a potent HSV-1 backbone with payloads added to maximize immunogenic cell death and the induction of a systemic anti-tumor immune response. The RPx platform has a unique dual local and systemic mechanism of action (MOA) consisting of direct selective virus-mediated killing of the tumor resulting in the release of tumor derived antigens and altering of the tumor microenvironment (TME) to ignite a strong and durable systemic response. This MOA is expected to be synergistic with most established and experimental cancer treatment modalities, and, with an attractive safety profile the RPx platform has the versatility to be developed alone or combined with a variety of other treatment options.
