- RP1 in solid organ transplant recipients with skin cancers (ARTACUS): The Company continues to enroll patients into its ARTACUS clinical trial of RP1 monotherapy in solid organ transplant recipients with skin cancers and expects to provide a data update in H1 2023.
- Development of RP1 for the neoadjuvant treatment of CSCC: Protocol development is underway for the testing of RP1 alone and combined with anti-PD1 therapy for the neoadjuvant treatment of CSCC, with clinical trial initiation expected in H1 2023.
RP2 and RP3 Update
- RP2 alone and in combination with Opdivo in difficult-to-treat cancers: The Company continues to enroll patients in the expansion cohorts of the Phase 1 clinical trial evaluating RP2 in patients with tumor types of particular interest (gastro-intestinal [GI] cancers, breast cancer, lung cancer, head and neck cancer and uveal melanoma). The Company had previously fully enrolled the cohorts evaluating RP2 monotherapy (n=9) and RP2 in combination with Opdivo (n=30) (data presented in Nov 2020 and Nov 2021). Initial data from the RP2 expansion cohorts is expected around the end of this year.
- RP3 alone and in combination with Opdivo in difficult-to-treat cancers: The Company completed enrollment in the initial part of its Phase 1 clinical trial with RP3 alone. Following determination of the recommended Phase 2 dose (RP2D), the Company is enrolling patients in the cohort evaluating RP3 combined with Opdivo, with focus on patients with GI cancers, breast cancer, lung cancer and head and neck cancer. Initial data for this RP3 combination cohort is expected around the end of this year. Additional monotherapy patients will also be enrolled.
- Phase 2 development program: The Company remains on track to initiate its Phase 2 development program with RP2/3 in the first quarter of 2023. As previously announced, this program is intended to include Phase 2 clinical trials in squamous cell carcinoma of the head and neck (SCCHN; locally advanced and recurrent/metastatic), hepatocellular carcinoma (HCC; first line and second line) and colorectal cancer (CRC; third line), combined with current standard of care where appropriate.
Financial Highlights
- Cash Position: As of June 30, 2022, cash, cash equivalents and short-term investments were $395.1 million, as compared to $395.7 million as of March 31, 2022. Cash utilized in operating activities in advancing the Company’s expanded clinical development plan was offset by $31.0 million in net proceeds generated from the sale of common stock under the Company’s at-the-market facility.
Based on the current operating plan, Replimune believes that existing cash, cash equivalents and short-term investments will fund operating expenses and capital expenditure requirements into the second half of 2024, excluding any confirmatory trial required by the FDA or other regulatory body.
- R&D Expenses: Research and development expenses were $29.5 million for the first quarter ended June 30, 2022, as compared to $18.6 million for the first quarter ended June 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 $2.6 million in stock-based compensation expenses for the first quarter ended June 30, 2022.
- S,G&A Expenses: Selling, general and administrative expenses were $11.4 million for the first quarter ended June 30, 2022, as compared to $8.8 million for the first quarter ended June 30, 2021. The increase was primarily driven by personnel related costs, including sales and marketing personnel associated with pre-launch planning and build of the Company’s commercial infrastructure. Selling, general and administrative expenses included $4.6 million in stock-based compensation expenses for the first quarter ended June 30, 2022.
- Net Loss: Net loss was $42.3 million for the first quarter ended June 30, 2022, as compared to a net loss of $27.3 million for the first quarter ended June 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 comprises approximately 180 evaluable 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 in which the costs of the trial are shared 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.
