Summary

This study tests whether a spray made from spirulina (a type of algae) can prevent or reduce severe mouth sores in people receiving radiation for head and neck cancer. About 70 patients will use either the spirulina spray or a placebo spray during their radiotherapy. The goal is to see if the spray lowers the chance of developing painful sores that make eating difficult.

What this could mean

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

Active substance: spirulina-derived oral spray
What this could lead to: If it works, this could provide a natural, low-cost option to reduce severe mouth pain during radiotherapy, helping patients eat and maintain quality of life.
What could go wrong: This is a small Phase 2 trial with only 70 participants, so results may not apply broadly. The spray may not outperform placebo, and allergic reactions to spirulina are possible.
