What this research studies

You would receive an injection of a specially designed oncolytic virus that delivers a CD40 ligand (MEM40) and type I interferon directly into the tumor. The project tests the approach in mice and in people by collecting tumor biopsies and blood samples to track CD8 T cells and changes in the tumor microenvironment. Investigators will measure whether the treatment increases the number and activity of tumor-reactive T cells and changes immune signals in and around tumors. If safe and promising, the work is intended to inform new intratumoral treatments that could be combined with existing immunotherapies.

Who could benefit from this research

Good fit: Ideal candidates are people with accessible solid tumors who can undergo intratumoral injection, tumor biopsies, and serial blood draws, such as patients treated at an academic cancer center.

Not a fit: Patients with hematologic (blood) cancers, those who are severely immunocompromised, or those whose tumors cannot be safely injected or biopsied are unlikely to benefit from this intratumoral approach.

Why it matters

Potential benefit: If successful, this approach could increase tumor-specific T cells and improve responses to immunotherapies for some patients with solid tumors.

How similar studies have performed: Earlier oncolytic viruses and CD40-targeting therapies have shown encouraging immune effects in some trials, but combining in situ CD40L expression with type I interferon delivery is a relatively novel approach.
