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.

| Incidence of Grade 2 or Higher Acute Radiation Dermatitis (RTOG Criteria) | Acute radiation dermatitis is assessed by trained radiation oncologists according to the Radiation Therapy Oncology Group (RTOG) acute radiation morbidity scoring criteria. The RTOG grading system categorizes acute radiation dermatitis into grades 0 to 4, with higher grades indicating more severe skin reactions. Grade 0 indicates no visible skin changes; Grade 1 indicates faint erythema or dry desquamation; Grade 2 indicates moderate to brisk erythema or patchy moist desquamation, mainly confined to skin folds; Grade 3 indicates confluent moist desquamation outside of skin folds or bleeding induced by minor trauma; and Grade 4 indicates skin necrosis or ulceration of full-thickness dermis, or spontaneous bleeding. The incidence of Grade 2 or higher acute radiation dermatitis is defined as the proportion of participants who develop Grade 2, Grade 3, or Grade 4 dermatitis at any time during radiotherapy or within the post-radiotherapy follow-up period. | The evaluation period is approximately 14 weeks to 14.5 weeks. |

| Overall Health Status and Core Dimensions of Quality of Life | European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) This instrument is a 30-item patient-reported outcome (PRO) measure designed to evaluate core aspects of health-related quality of life in cancer patients, including 5 functional scales (physical, role, cognitive, emotional, social), 3 symptom scales (fatigue, pain, nausea and vomiting), one global health status/quality of life scale, and 6 single-item symptom measures. Scores are linearly transformed to a range of 0-100. For the functional scales and the global health status scale, higher scores indicate better functional levels or quality of life; for the symptom scales/items, higher scores indicate greater symptom burden. |

| Topical application of placebo | Other | The placebo topical formulation will be composed of inactive ingredients and will be matched in appearance, texture, and administration regimen to the active Periplaneta americana-derived Meilian Fuxin Solution, and participants will also receive standard skin care for radiation dermatitis according to institutional clinical practice guidelines. |
|
| Radiotherapy | Radiation | One of the inclusion criteria for the study was that patients with squamous carcinoma of the head and neck (including nasopharyngeal carcinoma) needed to receive either radiotherapy alone or simultaneous radiotherapy and chemotherapy. |
|
The time from the start of radiotherapy to the first documented occurrence of Grade 3 or Grade 4 radiation dermatitis, as assessed according to the Radiation Therapy Oncology Group (RTOG) acute radiation morbidity scoring criteria. |
| The evaluation period is approximately 14 weeks to 14.5 weeks. |
| The duration of any-grade Radiation Dermatitis | The first determination of radiation dermatitis to the first instance of non-radiation dermatitis, without a subsequent instance of radiation dermatitis. | The evaluation period is approximately 14 weeks and 14.5 weeks. |
| Change in Radiation Dermatitis Severity Score using the RISRAS Scale | The change in radiation dermatitis severity, as measured by the Radiation-Induced Skin Reaction Assessment Scale (RISRAS), which ranges from 0 to 24, with higher scores indicating more severe skin reactions. Scores will be assessed at baseline (before the first day of radiotherapy), weekly during radiotherapy, and at follow-up visits up to 8 weeks after completion of radiotherapy. | The evaluation period is approximately 14 weeks and 14.5 weeks. |
| Change in Patient Quality of Life using the Skindex-16 | The change in patient-reported quality of life related to skin symptoms, as measured by the Skindex-16 Dermatology Life Quality Instrument, which ranges from 0 to 100, with higher scores indicating worse quality of life. Scores will be assessed at baseline (before the first day of radiotherapy), weekly during radiotherapy, and at follow-up visits up to 8 weeks after completion of radiotherapy. | The evaluation period is approximately 14 weeks and 14.5 weeks. |
| Radiotherapy Interruption due to Radiation Dermatitis | The occurrence of any temporary interruption, delay, or discontinuation of radiotherapy attributable to radiation dermatitis, as documented in the medical record. The reason for interruption will be confirmed by the treating radiation oncologist. | The time period is the period from the start of radiotherapy to the completion of radiotherapy.The evaluation period is approximately 6 weeks and 6.5 weeks. |
| Adverse events | Common Terminology Criteria for Adverse Events (CTCAE) 5.0 version | The evaluation period is approximately 14 weeks and 14.5 weeks. |
| The total evaluation period is approximately 14 to 14.5 weeks. |
| Head and Neck Cancer-Specific Symptoms | The EORTC QLQ-H&N35 is a patient-reported outcome (PRO) instrument specifically designed to assess disease-related symptoms and treatment-related side effects in patients with head and neck cancer. It comprises 35 items, organized into seven multi-item subscales (pain, swallowing, senses, speech, social eating, social contact, and sexuality) and eleven single-item measures (such as dental problems, problems opening mouth, sticky saliva, coughing, etc.). All subscale and single-item scores are linearly transformed to a 0-100 scale using a standardized scoring algorithm. Interpretation of Scores: For all subscales and single items, higher scores represent more severe symptoms or greater symptom burden. | The total evaluation period is approximately 14 to 14.5 weeks. |
| The number of patients who missed five or more consecutive radiation fractions | The number of patients who missed five or more consecutive radiations and the reasons for this are recorded during radiotherapy. | The evaluation period is approximately 6 weeks and 6.5 weeks. |
