What this trial studies

This clinical trial evaluates the safety, tolerance, and efficacy of hydroxychloroquine sulfate tablets in preventing and treating oral mucositis and dysgeusia in patients undergoing radiotherapy for non-metastatic head and neck malignant tumors. Participants will be randomly assigned to receive either hydroxychloroquine or a placebo. The study aims to determine whether hydroxychloroquine can effectively reduce the incidence and severity of oral mucositis associated with radiation treatment.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-80 with non-metastatic head and neck cancers who are scheduled to receive radiotherapy.

Not a fit: Patients with a history of head and neck radiotherapy or those with severe underlying health conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve the quality of life for patients undergoing radiotherapy by reducing painful oral mucositis.

How similar studies have performed: While there have been studies on the use of hydroxychloroquine for various conditions, this specific application for radiation-induced oral mucositis is novel and has not been extensively tested.
