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.
|
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.

Foranstaltningsbeskrivelse |
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

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.
|
Up to 8 weeks (from initiation to completion of radiotherapy)
|
|
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.
|
|
Skin microbiome composition and diversity
Tidsramme: Baseline and end of radiotherapy (approximately 8 weeks after radiotherapy initiation)
|
Skin microbiome composition and diversity will be assessed as an exploratory endpoint using 16S rRNA gene sequencing.
Skin swab samples will be collected from the irradiated skin area at baseline (before radiotherapy initiation) and at completion of radiotherapy.
|
Baseline and end of radiotherapy (approximately 8 weeks after radiotherapy initiation)
|
|
Number of participants with treatment-related adverse events as assessed by CTCAE v5.0
Tidsramme: From 1 week before radiotherapy to 4 weeks after completion of radiotherapy.
|
Common Terminology Criteria for Adverse Events (CTCAE) 5.0 version.
