New lozenge aims to ease radiation mouth sores for hours

NCT ID NCT07672236

First seen Jun 27, 2026 · Last updated Jul 14, 2026 · Updated 4 times

Summary

This phase 3 trial tests whether a lozenge called BupiZenge, which contains the long-acting painkiller bupivacaine, can relieve mouth pain from radiation therapy better than the standard lidocaine rinse. About 150 adults with head and neck cancer will be randomly assigned to one of the two treatments. The main goal is to measure pain reduction over three hours after taking the medicine on the last day of radiation.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
bupivacaine lozenge (BupiZenge)
What this could lead to
If it works, this could provide longer-lasting pain relief for mouth sores caused by radiation, reducing the need for strong opioids.
What could go wrong
This is still a trial, so results may not show a clear benefit over lidocaine. Pain relief varies per person, and side effects are possible.
