StrataXRT in Preventing Radiation Dermatitis in Pediatric Patients Undergoing Radiation Therapy to the Brain or Spinal Cord

This phase I trial studies the side effects of a silicone topical wound dressing (StrataXRT) and to see how well it works in preventing radiation dermatitis (skin burns and side effects caused by radiation) in pediatric patients undergoing radiation therapy. StrataXRT may help prevent or decrease severe skin rash, pain, itching, skin peeling, and dry skin in pediatric patients undergoing radiation therapy to the brain or spinal cord.

PRIMARY OBJECTIVES: I. To estimate the safety (defined using the Common Terminology Criteria for Adverse Events \[CTCAE\], version 5.0) of StrataXRT and placebo by assessing gel-associated toxicities among pediatric patients, aged 2-17 undergoing proton cerebrospinal irradiation (CSI) for central nervous system (CNS) tumors. II. To estimate the efficacy of StrataXRT as a preventative agent for radiation-associated dermatitis among pediatric patients, aged 2-17 undergoing proton CSI for CNS tumors. SECONDARY OBJECTIVES: I. To explore the relationship between dosing and the efficacy of StrataXRT. II. To explore the relationship between the use of StrataXRT and parent-reported symptom experience, as measured by the Radiation-Induced Skin Reaction Assessment Scale (RISRAS). III. To explore compliance with the application of treatment as documented in a study log by participants. OUTLINE: Beginning first day of CSI proton radiation therapy, caregivers apply StrataXRT gel to half of the patient's forehead and one ear and placebo to the other half of the forehead and the other ear twice daily (BID) until the last day of radiation therapy.
