Improving radiation for cervical cancer by targeting glutamine use

Optimizing radiation therapy through the manipulation of glutamine metabolism

NIH-funded research Washington University · NIH-11162381

This project aims to see whether blocking cancer cells' use of glutamine helps radiation control cervical cancer better.

What this research studies

The team will run laboratory studies and an investigator-initiated clinical trial combining a glutaminase inhibitor (CB-839) with standard chemoradiation for cervical cancer. In lab models they will examine how blocking glutamine affects both tumor cells and immune cells in the tumor environment, including shifting macrophages toward a more tumor-fighting state. Because radiation can stimulate anti-tumor immunity, the researchers expect the drug and radiation may work together to improve long-term tumor control. If promising, patients with locally advanced or radiation-resistant cervical cancer will be enrolled at Washington University to test safety and early signs of benefit.

Who could benefit from this research

Good fit: Adults with locally advanced or radiation-resistant cervical cancer who can receive chemoradiation and enroll in an early-phase clinical trial are the most likely candidates.

Not a fit: People with cancers other than cervical cancer, those who cannot tolerate chemoradiation, or tumors that are not glutamine-dependent are less likely to benefit.

Why it matters

Potential benefit: If successful, this approach could make radiation more effective, reduce recurrence, and improve outcomes for people with radiation-resistant cervical cancer.

How similar studies have performed: Preclinical studies and early-phase trials in other cancers suggest glutaminase inhibition can slow tumors and enhance immunity, but combining CB-839 with radiation for cervical cancer is largely novel.
