Detaljeret beskrivelse

Radiotherapy (RT) is a cornerstone treatment for patients with head and neck cancer and may be administered as definitive, adjuvant, or concurrent therapy with chemotherapy depending on disease stage and clinical indication. Despite its therapeutic benefits, RT is frequently associated with a range of acute toxicities, among which radiation dermatitis is one of the most common and clinically relevant adverse effects. Radiation-induced skin injury may present during or shortly after the course of radiotherapy and can significantly impact patient comfort, treatment adherence, and overall quality of life. Severe cases may lead to treatment interruption or dose modification, potentially compromising oncologic outcomes. The incidence of acute radiation dermatitis in patients with head and neck cancer has been reported to be high, with a substantial proportion of patients developing at least moderate-grade skin reactions during the course of radiotherapy. However, current preventive and therapeutic strategies remain limited, and no universally accepted standard of care has been established. Existing supportive measures are primarily empirical and have shown variable efficacy in reducing the severity or progression of skin toxicity. Superoxide dismutase (SOD) is an endogenous antioxidant enzyme with the ability to catalyze the dismutation of superoxide radicals into oxygen and hydrogen peroxide, thereby reducing oxidative stress-induced cellular damage. Given that oxidative stress is a key mechanism underlying radiation-induced skin injury, topical application of SOD-based formulations may provide a biologically plausible approach for mitigating radiation dermatitis. Based on this rationale, the present clinical trial is designed to investigate the efficacy and safety of a topical SOD skin spray in preventing and reducing acute radiation dermatitis in patients with head and neck cancer undergoing radiotherapy.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Placebo komparator: Placebo excipient spray
A placebo spray consisting of the excipient formulation without superoxide dismutase, which is the same as the experimental group in appearance.
Andet: Placebo Spray
Patients are instructed to apply a placebo excipient spray without superoxide dismutase evenly to the entire radiotherapy-treated skin area, approximately 3 sprays per application, five times daily, following the same schedule as the experimental group. Treatment is initiated at the start of radiotherapy and continued until the occurrence of grade ≥2 radiation dermatitis or up to one week after completion of radiotherapy, whichever occurs first. Patients are instructed to keep the irradiated skin clean and dry and to avoid the use of other topical agents in the treatment area.
Eksperimentel: Superoxide dismutase containing skin spray
A topical skin spray containing superoxide dismutase
Medicin: A topical superoxide dismutase skin spray
Patients are instructed to apply a topical superoxide dismutase-containing spray evenly to the entire radiotherapy-treated skin area, approximately 3 sprays per application, five times daily. Treatment is initiated at the start of radiotherapy and continued until the occurrence of grade ≥2 radiation dermatitis or up to one week after completion of radiotherapy, whichever occurs first. Patients are instructed to keep the irradiated skin clean and dry and to avoid the use of other topical agents in the treatment area.

Tidsramme
Incidence of grade ≥ 2 ARD
Tidsramme: From the start of radiotherapy to 4 weeks after completion of radiotherapy
Patients are assessed weekly for radiation dermatitis by an experienced radiation oncology nurse according to the Radiation Therapy Oncology Group (RTOG) scale. The RTOG scale categorizes acute skin toxicity into grades 0-4, with the higher the grade the more severe the patient's acute radiation dermatitis. Grade 0 means no change over baseline. Grade 1 means follicular, faint, or dull erythema; epilation, dry desquamation, or decrease in sweating. Grade 2 means tender, bright erythema; patchy, moist desquamation or moderate edema. Grade 3 means confluent, moist desquamation other than skin folds; pitting edema. Grade 4 means ulceration, hemorrhage, necrosis.
From the start of radiotherapy to 4 weeks after completion of radiotherapy

Tidsramme
Generel Helbredsstatus og Kerneaspekter af Livskvalitet
Tidsramme: Den samlede evalueringsperiode er cirka 14 til 14,5 uger.
European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) Dette instrument er et patientrapporteret resultatmål (PRO) med 30 emner, designet til at evaluere kerneaspekter af sundhedsrelateret livskvalitet hos kræftpatienter, herunder 5 funktionelle skalaer (fysisk, rolle, kognitiv, følelsesmæssig, social), 3 symptomskalaer (træthed, smerte, kvalme og opkastning), en global sundhedsstatus/livskvalitets skala, og 6 enkelt-emne symptommålinger. Scorerne lineært transformeres til en rækkevidde på 0-100. For de funktionelle skalaer og den globale sundhedsstatus skala indikerer højere scorer bedre funktionsniveauer eller livskvalitet; for symptomskalaer/emner indikerer højere scorer større symptombelastning.
Den samlede evalueringsperiode er cirka 14 til 14,5 uger.
Symptomer specifikke for hoved- og halskræft
Tidsramme: Den samlede evalueringsperiode er cirka 14 til 14,5 uger.
EORTC QLQ-H&N35 er et patientrapporteret resultatinstrument (PRO), der er specifikt designet til at vurdere sygdomsrelaterede symptomer og behandlingsrelaterede bivirkninger hos patienter med hoved- og halskræft. Det består af 35 punkter, organiseret i syv flerpunktsskalaer (smerter, synkning, sanser, tale, social spisning, social kontakt og seksualitet) og elleve enkeltpunktsmålinger (såsom tandproblemer, problemer med at åbne munden, klæbrig spyt, hoste osv.). Alle skala- og enkeltpunktsscores omregnes lineært til en 0-100 skala ved hjælp af en standardiseret scoring-algoritme. Scorefortolkning: For alle skalaer og enkeltpunkter repræsenterer højere scores mere alvorlige symptomer eller større symptombelastning.
Den samlede evalueringsperiode er cirka 14 til 14,5 uger.
Radiotherapy interruption rate
Tidsramme: Up to 8 weeks (from initiation to completion of radiotherapy)
Radiotherapy interruption is defined as an unplanned prolongation of the radiotherapy schedule resulting in a delay of ≥5 days compared with the planned treatment schedule, excluding scheduled breaks.

Patient-reported skin symptoms from the Skindex-16
Tidsramme: From 1 week before radiotherapy to 4 weeks after completion of radiotherapy.
The Skindex-16 is a commonly used tool to measure the effect of skin diseases on the skin-related QoL of patients. Skindex-16 consists of domain scores that assess how symptoms, emotions, and functioning from the skin issue affect the QOL of patients with acne. The overall score averages the 3 domain scores, all of which are normalized to a 0 to 100 scale, where 0 indicates that their skin condition has no impact on QOL and 100 represents maximal impact on QOL for the worse.
From 1 week before radiotherapy to 4 weeks after completion of radiotherapy.
