Program Highlights & Milestones
RP1
- CERPASS clinical trial of RP1 combined with Libtayo® (cemiplimab-rwlc) in CSCC
- The trigger for the primary analysis from the registration-directed CERPASS clinical trial occurred in late June and data collection activities are now complete. The independent review process is expected to complete shortly, triggering a defined process timeline to disclosure in early December.
- Assuming positive data demonstrating overall clinical benefit, the Company plans to submit a Biologics License Application (BLA) for RP1 in Q2 2024.
- RP1 combined with Opdivo® (nivolumab) in anti-PD1 failed melanoma
- The Company will present initial snapshot data for all patients on its conference call in early December by which point all patients will have had at least 6 months follow up. The Company also plans to provide a regulatory update including the design of the intended confirmatory clinical trial to support a potential approval under the accelerated pathway. Planning for the confirmatory study is underway to ensure it has commenced ahead of any BLA submission. The per protocol primary analysis will take place 12 months post the last patient enrolled. Accordingly, the Company plans to submit the BLA in Q3 2024.
- RP1 combined with Opdivo in anti-PD1 failed non-melanoma skin cancers (NMSC)
- Recruitment remains ongoing into the cohort of patients with anti-PD1 failed NMSC, including CSCC. The Company plans to provide a data update of the first 30 patients with at least 6 months follow up on its conference call in early December.

About CERPASS
CERPASS is Replimune's registration-directed randomized, global Phase 2 clinical trial to compare the effects of Libtayo® (cemiplimab-rwlc) alone versus a combination of Libtayo and Replimune's investigational oncolytic immunotherapy RP1. The clinical trial enrolled 211 patients with locally advanced or metastatic cutaneous squamous cell carcinoma who are naïve to anti-PD-1 therapy. The clinical trial will evaluate complete response rate and overall response rate as its two independent primary efficacy endpoints as assessed by independent review, as well as secondary endpoints including duration of response, progression-free survival, and overall survival. The clinical trial is being conducted under a clinical trial collaboration agreement with Regeneron and full commercial rights retained by Replimune. Libtayo is a registered trademark of Regeneron.
About IGNYTE
IGNYTE is Replimune's multi-cohort Phase 1/2 clinical trial of RP1 in combination with Opdivo® (nivolumab). There are 3 tumor specific cohorts in this clinical trial including a cohort in anti-PD1 failed melanoma with registrational intent that has completed enrollment with 140 patients enrolled. 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 currently enrolling and are in non-melanoma skin cancers which includes both naïve and anti-PD1 failed CSCC, and in anti-PD1 failed microsatellite instability high, or MSI-H/dMMR tumors. This trial is being conducted under a collaboration and supply agreement with Bristol-Myers Squibb. Opdivo is a registered trademark of Bristol-Myers Squibb.
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 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 & 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, but does not express GM-CSF. 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 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 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 to ignite a strong and durable systemic response. This MOA is 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.
