What this research studies

Researchers used a computational platform to find a drug target and a small molecule that could protect mouth lining from radiation damage. They gave the compound by mouth in a well-established hamster model of radiation-induced oral mucositis and saw shorter ulcer duration and, in some animals, complete prevention of ulcers. The compound targets a family of BET bromodomain proteins and the team identified a specific domain that appears safest for this effect. This program is in preclinical development at a San Diego biotech company to prepare for possible human testing.

Who could benefit from this research

Good fit: People receiving radiation therapy to the head or neck who are at risk for developing oral mucositis would be the likely candidates for this therapy in future trials.

Not a fit: People not undergoing head or neck radiation or whose mouth sores are caused by unrelated conditions are unlikely to benefit from this treatment.

Why it matters

Potential benefit: If successful, the drug could reduce or prevent painful mouth sores and speed recovery for patients receiving head and neck radiotherapy.

How similar studies have performed: BET-family inhibitors have been given to cancer patients with an established safety profile, but using them specifically to prevent radiation mouth sores is a novel approach with promising animal data.
