Using tumor-targeting viruses to boost CAR T cell treatment for solid tumors

Re-purposing Oncolytic Virotherapy to Re-invigorate CAR T Cell Therapy for Solid Tumors.

NIH-funded research Mayo Clinic Rochester · NIH-11237992

This work aims to help CAR T cell therapy work better for people with solid tumors by combining CAR T cells with cancer-killing viruses that ramp up the immune response.

What this research studies

Researchers take CAR T cells and load them with oncolytic (cancer-targeting) viruses outside the body, then deliver them systemically to create a more inflammatory tumor environment and improve CAR T trafficking and function. In mouse models this produced dual-specific, memory-like CAR T cells that persisted longer and had stronger anti-tumor activity than CAR T or virus alone. The project will refine how the virus is paired with CAR T cells, optimize dosing and delivery, and work toward approaches that could be translated into human trials. The goal is a safe regimen that makes CAR T therapy more effective for a wider range of solid tumors.

Who could benefit from this research

Good fit: Ideal candidates would be people with solid cancers who are eligible for CAR T–based clinical trials or for experimental combination therapies at a specialized center.

Not a fit: People with blood cancers already well served by existing CAR T products or those with severe immune suppression or contraindications to viral therapies may not benefit from this approach.

Why it matters

Potential benefit: If successful, this approach could make CAR T treatment more effective and longer-lasting for patients with solid tumors that currently respond poorly.

How similar studies have performed: Similar combinations of oncolytic viruses and cellular immunotherapies have shown promising results in animal studies, but human data remain limited.
