Market Overview and Growth Snapshot
The Oncolytic Virus Immunotherapy Market Size was valued at 3,610 USD Million in 2024. The Oncolytic Virus Immunotherapy Market is expected to grow from 4,300 USD Million in 2025 to 25 USD Billion by 2035. The Oncolytic Virus Immunotherapy Market CAGR (growth rate) is expected to be around 19.2% during the forecast period (2025 – 2035).
Market Overview
Oncolytic virus immunotherapy involves the use of genetically modified or naturally occurring viruses that selectively infect and destroy cancer cells while stimulating the patient’s immune system to attack tumors. These therapies offer dual benefits—direct tumor lysis and long-term immune activation—making them a promising alternative to conventional cancer treatments such as chemotherapy and radiation.
Growing success in treating solid tumors, including melanoma, glioblastoma, and lung cancer, is significantly strengthening market momentum.
Key Drivers and Market Dynamics
The market is primarily driven by the rising global cancer burden and the limitations of traditional oncology treatments. Increasing clinical trial success rates for viral-based immunotherapies and advancements in genetic engineering are further accelerating adoption. Strong funding support from governments, biotechnology firms, and research institutions is also contributing to rapid innovation.
Additionally, growing interest in combination therapies—where oncolytic viruses are used alongside immune checkpoint inhibitors—is expanding therapeutic potential and improving patient outcomes.
