NCT07538934

Brief Summary

This is a prospective, open-label, randomized, controlled, multicenter phase II study evaluating the efficacy and safety of Kangfu Spray for the prevention of radiation-induced oral mucositis in patients with histologically confirmed oral malignancies receiving intensity-modulated radiotherapy (IMRT), with or without concurrent platinum-based chemotherapy. Eligible participants will undergo definitive or postoperative adjuvant IMRT according to multidisciplinary team recommendations. Participants in the experimental group will receive Kangfu Spray prophylactically from the first day of radiotherapy until completion of radiotherapy, in addition to standard oral care. The primary endpoint is the incidence of severe radiation-induced oral mucositis, defined as World Health Organization (WHO) grade 3 or higher. Secondary endpoints include time to onset and duration of severe oral mucositis, incidence and duration of any oral mucositis, oral ulcer and pain scores, radiotherapy interruption, opioid analgesic use, nutritional indicators, quality of life, and safety. Exploratory analyses will evaluate lymphocytes, inflammatory factors, and microbiota in blood and saliva.

    Incidence of severe oral mucositis defined as World Health Organization (WHO) grade 3 or higher.

    From the start of radiotherapy to 1 month after completion of radiotherapy

Study Arms (2)

Kangfu Spray plus Standard Oral Care

EXPERIMENTAL

Participants receive Kangfu Spray prophylaxis in addition to standard oral care, oral hygiene education, and supportive care during intensity-modulated radiotherapy (IMRT), with or without concurrent platinum-based chemotherapy.

Device: Kangfu Spray

Standard Oral Care

ACTIVE COMPARATOR

Participants receive standard oral care, including oral hygiene education, routine oral care, and symptom-directed supportive treatment as needed during IMRT, with or without concurrent platinum-based chemotherapy.

Other: Standard Oral Care

Interventions

Standard oral care includes oral hygiene education, routine oral care, and symptom-directed supportive treatment as needed.

Kangfu Spray plus Standard Oral Care

Standard oral care includes oral hygiene education, routine oral care, and symptom-directed supportive treatment as needed during IMRT.
