Some of the key facts of the Oncolytic Virus Therapies Market Report:

• Although IMLYGIC was the first therapy of its kind, its sales and revenue have been restricted due to its narrow patient eligibility (only about 10% of patients unable to undergo surgery) and its comparatively lower effectiveness versus other melanoma immunotherapies. As a result, it is expected to maintain only a modest market share in the 7MM over the forecast period.
• Key Oncolytic Virus Therapies Companies: CG Oncology, Imugene, Amgen, Daiichi Sankyo, Genelux, Replimune, Binhui Biopharmaceutical, Zhejiang Cancer Hospital, and others
• Key Oncolytic Virus Therapies Therapies: Cretostimogene grenadenorepvec, CF33, IMLYGIC (T-VEC), DELYTACT (G47Δ), Olvi-Vec, RP1, OH2 injection, H101, Camrelizumab, and others
• The Oncolytic Virus Therapies market is expected to surge due to the disease's increasing prevalence and awareness during the forecast period. Furthermore, launching various multiple-stage Oncolytic Virus Therapies pipeline products will significantly revolutionize the Oncolytic Virus Therapies market dynamics.

Oncolytic Virus Therapies Overview

Oncolytic virus therapies are a type of cancer treatment that use specially engineered or naturally occurring viruses to infect and destroy cancer cells while sparing healthy cells. Once inside the tumor, these viruses replicate, causing cancer cells to burst and die. They also stimulate the body’s immune system to recognize and attack cancer more effectively. This dual action direct tumor destruction and immune activation makes oncolytic viruses a promising and emerging area in oncology.

Recent Developments In The Oncolytic Virus Treatment Landscape:

• In November 2025, November has already brought several noteworthy advancements across the oncology landscape. In just the first two weeks, the FDA has granted multiple approvals and regulatory updates for treatments in breast cancer, leukemia, and gynecologic cancers. Moreover, data presented at the 2025 Society for Immunotherapy of Cancer Annual Meeting highlighted emerging therapeutic approaches that may offer benefits across a range of clinical settings.
• In October 2025, In October 2025, the U.S. FDA accepted Replimune’s resubmitted Biologics License Application (BLA) for RP1 in combination with nivolumab (Opdivo®) for patients with advanced, PD-1–refractory melanoma, with a final regulatory decision anticipated by April 2026. Oncolytic viral immunotherapies are an emerging category of cancer treatments that work by directly destroying tumor cells while simultaneously activating the immune system. RP1 (vusolimogene oderparepvec), created by Replimune Inc., is a genetically modified herpes simplex virus type 1 (HSV-1) engineered to selectively replicate within tumors, trigger immunogenic cell death, and boost systemic antitumor immune responses.
• In October 2025, Replimune Group reported that the US FDA has accepted its resubmitted biologics license application (BLA) for RP1 (vusolimogene oderparepvec) combined with nivolumab for treating advanced melanoma in patients who have progressed on prior anti–PD-1 therapy. The FDA has set a Prescription Drug User Fee Act (PDUFA) date of April 10, 2026, reflecting a Class II resubmission review schedule.
