Changing the glioblastoma tumor environment to boost immune therapy

Reprogramming the tumormicroenvironment to improve immunotherapy of glioblastoma

['FUNDING_R01'] · MASSACHUSETTS GENERAL HOSPITAL · NIH-11294306

This project tests whether blocking Wnt signaling together with PD‑1 immunotherapy can help people with glioblastoma by reducing immune‑suppressing cells and increasing tumor‑fighting immune cells.

What this research studies

Researchers are combining a drug that blocks Wnt signaling (a porcupine inhibitor) with anti‑PD‑1 immunotherapy to reshape the immune environment inside glioblastoma tumors. They will study how this combination changes key immune cells such as dendritic cells and myeloid‑derived suppressor cells using lab models and human tumor samples. The team will compare tumors that respond versus those that resist the treatment to identify mechanisms of resistance and potential biomarkers. Findings aim to guide future clinical trials that could personalize immunotherapy for glioblastoma patients.

Who could benefit from this research

Good fit: Patients with glioblastoma (newly diagnosed or recurrent) who might be eligible for trials combining Wnt pathway inhibitors with PD‑1 blockers would be the ideal candidates.

Not a fit: Patients without glioblastoma, or whose tumors lack Wnt pathway activity or who cannot tolerate immunotherapy or Wnt inhibitors, may not benefit from this approach.

Why it matters

Potential benefit: If successful, this approach could make immunotherapy work for more glioblastoma patients and potentially extend survival.

How similar studies have performed: Immune checkpoint blockers alone have failed in phase III glioblastoma trials, but early preclinical mouse and lab studies combining a Wnt inhibitor with anti‑PD‑1 showed promising survival and immune changes, so this approach is novel with encouraging preclinical support.
