Topical Periplaneta Americana-Derived Meilian Fuxin Liquid for Radiation Dermatitis

A Single-Center, Two-Arm, Prospective Clinical Study Evaluating the Efficacy and Safety of a Topical Periplaneta Americana-Derived Regenerative Solution (Meilian Fuxin Liquid) for the Treatment of Radiation Dermatitis

To evaluate the efficacy and safety of topical Periplaneta americana-derived Meilian Fuxin Solution for the prevention of radiation dermatitis in patients undergoing radiotherapy.

The clinical trial aims to evaluate the efficacy and safety of topical Periplaneta americana-derived Meilian Fuxin Solution in preventing and reducing radiation dermatitis in patients undergoing radiotherapy. Participants will be assigned to receive either topical Meilian Fuxin Solution or a placebo formulation, applied twice daily to the irradiated skin area from the start of radiotherapy through completion of treatment. The placebo will be administered using an identical application regimen. Radiation dermatitis will be assessed at baseline and at regular intervals during and after radiotherapy using the Radiation Therapy Oncology Group (RTOG) criteria, and safety will be evaluated by monitoring local and systemic adverse events throughout the study period.
