Recent FDA Approvals Year Basis of Approval Relevance to RP1 Relatlimab + Nivolumab (OPDUALAG) 2022 • Randomized controlled trial • First-line treatment-naive patients • Now included in NCCN guidelines1 for second line (ORR 9-12%)2 • Approved post IGNYTE • >95% selected option for IGNYTE-3 control arm Lifileucel (AMTAGVI) + IL-2 regimen 2024 • Single arm • Previously treated with anti-PD-1 • ORR (31.5%, n=73); combination regimen with 7.5% mortality (n=160)3 • Precedent in similar setting (PD-1 failed melanoma) with single arm dataCC-13 Ongoing Collaboration with FDA through 2025 2021 2022 2023 2024 2025 Key alignments with FDA: • Potential flexibility on single trial, pending compelling evidence (2021) • Enroll real-world population (2021) • RECIST 1.1 (2023) • Analysis of all injected and non-injected lesions (2023) • Literature to support contribution of effect (2023) • IGNYTE-3 design (2023) • SAP and Independent review charter for response assessment (2024) Key alignments with FDA: Type B Meeting - IGNYTE: Study design (March) Type C Meeting - IGNYTE: Preliminary results & IGNYTE-3 design (September) Pre BLA Meeting (September) Breakthrough therapy designation (November) Productive review cycle >50 information requests and near final label (Jan-July) Priority review designation (January)CC-14 Initial FDA Clinical Review: Basis for Approval FDA BLA Clinical Review and Evaluation, July 15 2025 (obtained by Replimune through Freedom of Information Act) “…The reviewers acknowledge that the clinical benefit of VO in combination with nivolumab is based on results from a single arm trial with inherited biases including potential patient selection bias, like all single arm trials. However, with over 30 clinical information requests including 27 efficacy related clinical information requests with over 136 questions, the reviewers did not find any study conduct or data integrity issues. The IGNYTE trial (RPL-001-16) Phase 2 portion is an adequate and well-controlled trial which provides substantial evidence of effectiveness…”CC-15 Initial FDA Clinical Review: Recommended RP1 for Approval FDA BLA Clinical Review and Evaluation, July 15 2025 (obtained by Replimune through Freedom of Information Act) “…Based on the IGNYTE trial results, a comprehensive literature review, the life-threatening condition of the intended patient population, the absence of treatment with proven clinical benefit in the standard of care setting, and the precedent cases using durable ORR to support drug approvals in this population, the reviewers conclude that the efficacy and safety results from the IGNYTE trial have demonstrated substantial evidence of effectiveness of VO. The benefits of VO, used in combination with nivolumab, outweigh risks, representing an improvement over standard of care. The benefit over risk profile of VO in combination with nivolumab is superior to lifileucel treatment which is a multi-component regimen (preconditioning chemotherapy with cyclophosphamide and fludarabine followed by infusions of lifileucel and up to 6 doses of high dose IL-2) that is associated with high risks. Therefore, the reviewers recommend for accelerated approval of VO, used in combinations with nivolumab, for adult patients with confirmed disease progression on anti-PD-1 based therapy…”CC-16 Regulatory TopicsCC-17 Relevance of MOA to Response Assessment LOCAL IMMUNE EFFECT SYSTEMIC IMMUNE EFFECT • Direct oncolytic virus-mediated tumor lysis attracts antigen-presenting cells • Antigen-presenting cells internalize tumor antigens, leading to T cell activation • Activated T cells traffic systemically, driving long-term durable responses in both injected and non-injected tumorsCC-18 RECIST 1.1: Replimune vs. FDA Response Rate Analysis *If corrected for denominator = 25% (FDA sensitivity analysis) FDA ANALYSIS N=22 N=0 ORR 15.7%*, n/N=22/140 REPLIMUNE ANALYSIS N=22 N=25 ORR 33.6%, n/N=47/140 NON-INJECTED TARGET LESION ALL TARGET LESIONS INJECTED Patients with all target lesions injected should be includedCC-19 Replimune Position: Response Assessment FDA Issues from briefing document FDA Issue Replimune Position Application of RECIST 1.1 confounds interpretation of efficacy results “RECIST 1.1 specifies that tumor lesions subjected to loco-regional therapies are generally not considered measurable for response assessment…” • IGNYTE study - injected lesions should not be excluded because the intervention is pre-specified in the protocol – Protocol details the conditions under which such lesions would be considered measurable (Eisenhauer 2009) • RP1 has a dual mechanism of action that stimulates a systemic T cell response to destroy injected and non-injected lesionsCC-20 Replimune Position: Response Assessment 1.

NCCN, SITC, Ribas FDA Issue Replimune Position “Objective response data from the single-arm IGNYTE study is not of sufficient magnitude to overcome concerns about the contribution of effect, particularly in the absence of a reliable historical control…" • ORR of 33.6% (CR 16.4%) in IGNYTE is nearly 5x expected response for nivolumab alone and supports contribution of effect • FDA previously agreed to the use of literature to provide historical controls • Existing literature and expert opinions indicate patients who have definitively progressed on a prior anti-PD-1 are unlikely to respond to further anti-PD-1 monotherapy - yielding a 5-7% response rate1 • FDA patient-by-patient analysis (July 2025) concluded prior anti-PD-1 exhaustionCC-22 What You Will Hear Today Dual mechanism of action Kevin Harrington, MD, PhD, FRCP, FRCR, FRSB Professor of Biological Cancer Therapies Institute of Cancer Research Mechanism of Action Michael Wong, MD, PhD, FRCPc Clinician, IGNYTE Study Advisory Board Former Physician in Chief, Roswell Park Cancer Center Unmet Need Fills an unmet need Treats a serious, life-threatening condition Kostas Xynos, MD, PhD, MBA Chief Medical Officer, Replimune, Inc.
