Modified Dakin's Solution in Reducing Radiation-Induced Dermatitis in Patients With Head and Neck Cancer Undergoing Radiation Therapy

Overview

This randomized phase 3 trial studies how well modified Dakin's solution works in reducing radiation-induced dermatitis, a common skin reaction to radiation therapy, in patients with head and neck cancer undergoing radiation therapy. Modified Dakin's solution may reduce inflammation in the body, which may prevent or reduce dermatitis after radiation therapy. Radiation therapy in this study is regulatory medical care based on the patient's needs and the radiation oncologist's judgment. It is not possible nor necessary to explicitly define the dose or duration of treatment.

PRIMARY OBJECTIVES: I. To determine the proportion of patients who develop grade 3 radiation dermatitis (as defined by the Stanford Radiation Dermatitis Scoring System) as an adverse effect of radiation therapy or chemoradiation therapy for a head and neck cancer when initiating the use of prophylactic hypochlorite (HOCl) (modified Dakin's solution) at the start of therapy (experimental arm) compared to placebo (control arm). OUTLINE: Patients are randomized to 1 of 2 arms. ARM I (EXPERIMENTAL): Participants apply modified Dakin's solution (0.005% to 0.010%) topically to the skin of the arm up to 3 hours in advance of each radiation treatment. ARM II (CONTROL): Participants apply placebo solution (saline) topically to the skin of the arm up to 3 hours in advance of each radiation treatment. At the time that Stanford Radiation Dermatitis Scoring System (SRDSS) Grade E radiation dermatitis develops, the participant will transition to standard management for radiation dermatitis. SRDSS, by grade, is as follows. * A. No skin change * B. Faint, barely detectable erythema * C. Follicular rash, hyperpigmentation, evolving erythema * D. Dry desquamation, brisk erythema * E. Moist desquamation * F. Bleeding, ulceration, and/or infection SRDSS Grade E is roughly equivalent to the Common Terminology Criteria for Adverse Events (CTCAE) Version 4.03 Grade 3 radiation dermatitis, "Moist desquamation in areas other than skin folds and creases; bleeding induced by minor trauma or abrasion." After completion of study, patients are followed up at 6 to 10 weeks.
