Topical gel and mouthwash to prevent severe oral mucositis in people receiving head and neck radiation

Effect of a Novel Topical Composition on the Incidence of Severe Oral Mucositis in Head & Neck Cancer Radiated Patients and Quality of Life Assessed by PROMs. A Two Phases Study, Part of STOP OM PROJECT. Phase 2, Single Arm, Interventional, Longitudinal, Clinical Trial.

Not applicable Interventional Mucosa Innovations, S.L. · NCT05635929

This will test whether a topical gel and mouthwash (XCM-OM118) can reduce severe oral mucositis and improve quality of life for adults having radiation for head and neck cancer.

What this trial studies

The intervention uses a novel topical composition (XCM-OM118: olive oil, betaine, xylitol and other components) delivered as a non-rinsing gel and a mouthwash applied multiple times daily during radiotherapy and in a separate chronic phase. Phase 1 follows patients through the first six weeks of radiotherapy (with or without chemotherapy) to record incidence and severity of oral mucositis using the WHO scale plus structured patient-reported symptom questionnaires. Phase 2 enrolls patients at least six months after completing radiotherapy to record baseline quality of life using the University of Washington PROMs, then gives the oral regimen for one month and repeats the PROMs. Mucosa management is standardized across participants and outcomes focus on mucositis severity, pain, swallowing/speech effects, and PROMs-measured quality of life.

Who should consider this trial

Good fit: Ideal candidates are adults (18+) with head and neck cancer who are starting radiotherapy (with or without chemotherapy) for the acute phase or adults who completed radiotherapy at least six months ago for the chronic quality-of-life phase, and who can use the products and complete questionnaires.

Not a fit: Patients unlikely to benefit include those unable to properly use the products, those being treated for a different cancer, and chronic-phase patients taking xerostomia drugs such as pilocarpine or cevimeline who are excluded from the protocol.

Why it matters

Potential benefit: If successful, the product could lower rates of severe mucositis, reduce pain and treatment interruptions, and improve swallowing, speech, and overall post-treatment quality of life.

How similar studies have performed: Moisturizing and barrier-type topical approaches have shown symptom relief in small prior studies, but the specific XCM-OM118 composition is novel and not yet widely tested in larger trials.
