Combining radiation with drugs that block TGF‑beta and PD‑L1 for recurrent head and neck cancer

Treating recurrent HNSCC with radiation and dual TGF-Beta/PD-L1.

NIH-funded research University of Colorado Denver · NIH-11180120

This tests whether adding two immune‑targeting drugs that block TGF‑beta and PD‑L1 to radiation helps people whose head and neck cancer has come back respond better.

What this research studies

If your head and neck squamous cell carcinoma has recurred, doctors will give radiation as usual and add two drugs that aim to lift immune suppression by blocking TGF‑beta and PD‑L1. The team will collect tumor biopsies and blood samples to measure immune cells and levels of TGF‑beta and PD‑L1 before and after treatment. Researchers hope the combination will boost the radiation‑triggered anti‑tumor immune response and reduce treatment resistance. The approach was promising in mouse models and will be tested in patients at the study site.

Who could benefit from this research

Good fit: People with locally recurrent head and neck squamous cell carcinoma who are candidates for radiation and willing to provide biopsies and blood samples are the best fit.

Not a fit: Patients who are not eligible for radiation, have uncontrolled autoimmune disease, or whose tumors lack the relevant immune markers may not benefit.

Why it matters

Potential benefit: If successful, this could improve tumor control after radiation and lower the chance of radiation resistance or spread.

How similar studies have performed: PD‑1/PD‑L1 drugs are FDA‑approved for recurrent HNSCC but have low response rates, and combining TGF‑beta blockade with PD‑L1 has shown promise in preclinical models but is not yet proven in patients.
