Improving immune treatments for cancers that have spread to the brain

Official title: Optimizing systemic immunotherapy for personalized brain metastasis treatment

Funded at Stanford University · NIH-11174237 · Data updated 2026-11-12

Researchers will try blocking a molecule called TGF-β in lymph nodes to help immune therapies work better for people whose cancer has spread to the brain.

Who could benefit from this research

Could help

Adults whose cancer has spread to the brain, especially those being considered for immunotherapy or willing to provide tissue or blood samples, would be most relevant.

Less likely to help

Patients with cancers that have not spread to the brain, those in poor overall health who cannot receive immunotherapy, or those whose tumors do not rely on TGF-β–driven immunosuppression may not benefit directly from this work.

What this research studies

This project focuses on brain metastases, where cancer spreads to the brain and weakens the body's immune response. Researchers will study tumor-associated macrophages (TAMs) that produce TGF-β and track how these cells move between brain tumors and the tumor-draining lymph nodes. Using lab models and patient-derived samples, they will block TGF-β at the lymph nodes to see if that restores T cell priming and improves responses to checkpoint inhibitors or vaccine approaches like iPSC-based vaccines. Results could guide new combination therapies to make existing immunotherapies more effective for people with brain metastases.

Why it matters

Potential benefit: If successful, this work could make immunotherapies more effective against brain metastases and help patients live longer or have better disease control.

How similar studies have gone: Previous preclinical and early clinical work suggests TGF-β blockade can boost immunotherapy in some cancers, but applying this approach specifically to brain metastases is relatively new and still exploratory.
