The global oncology landscape is undergoing a major transformation as in vivo CAR-T therapy emerges as one of the most promising innovations in cancer immunotherapy. Unlike conventional ex vivo CAR-T treatments that require extraction and engineering of immune cells outside the patient’s body, in vivo CAR-T therapy directly reprograms T cells internally using advanced gene delivery technologies.
The global in vivo CAR-T therapy market was valued at USD 650 million in 2025 and is projected to grow from USD 861.25 million in 2026 to approximately USD 10,841.07 million by 2035, expanding at an extraordinary CAGR of 32.50% from 2026 to 2035. The market is being driven by the increasing prevalence of cancer, rising clinical trial activity, advancements in gene-editing technologies, and growing investment in next-generation immunotherapies.
As healthcare systems seek faster, scalable, and cost-efficient alternatives to traditional CAR-T manufacturing processes, in vivo CAR-T platforms are rapidly attracting attention from pharmaceutical companies, research institutions, and investors worldwide.
