Clinical Trial Summary

The main purpose of this trial is to investigate what happens to the trial drug in the body and to confirm that it is safe to use and effective for treating atopic dermatitis (AD) in children.

The trial will last up to maximum of approximately 194 weeks, and there will be up to 59 visits. The visits will be held approximately every second week for the first 68 weeks, then the visits will be held every six weeks for the rest of the treatment period. From week 26, every second visit will be held by phone and every second visit will be held on site.

The first part of the trial is called a screening period and will last between 2 and 6 weeks. After the screening period, the trial drug will be administered to the child by subcutaneous (SC) injection. The treatment period with tralokinumab is divided in 3 parts: 1.) initial treatment period for 16 weeks, 2.) open-label treatment period for 52 weeks and 3.) long-term extension treatment period for up to 106 weeks followed by a 14-week safety follow-up period.

All children will use an emollient twice daily (or more) for at least 14 days prior to start of treatment and will continue this treatment throughout the trial. If medically necessary, rescue treatment for AD is allowed at the discretion of the trial doctor.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Ctrough (trough concentration)		at Week 16
Primary	Cmax (maximum serum concentration)		between Week 12-Week 14 for Q2W (Week 12-Week 16 for Q4W)
Primary	AUC (area under the curve)		between Week 12-Week 14 for Q2W (Week 12-Week 16 for Q4W)
Primary	Tmax (time to maximum serum concentration)		between Week 12-Week 14 for Q2W (Week 12-Week 16 for Q4W)
Secondary	Number of treatment-emergent adverse events in the initial treatment period	An Adverse Event (AE) is defined as any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. An event will be considered treatment-emergent if started after the first use of IMP or if started before the first use of IMP and worsened in severity after first dose of IMP.	Week 0-Week 16
Secondary	Anti-drug antibodies (status) in the initial treatment period		Week 0-Week 16
Secondary	Number of treatment-emergent adverse events in the open-label treatment period	An AE is defined as any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. An event will be considered treatment-emergent if started after the first use of IMP or if started before the first use of IMP and worsened in severity after first dose of IMP.	Week 16-Week 68
Secondary	Anti-drug antibodies (status) in the open-label treatment period		Week 16-Week 68
Secondary	Change in Scoring Atopic Dermatitis (SCORAD)	The SCORAD is a validated tool to evaluate the extent and severity of atopic dermatitis (AD) lesions, along with subjective symptoms. The maximum total score is 103, with higher values indicating more severe disease.	from Week 0-Week 68
Secondary	Change in Patient-Oriented Eczema Measure (POEM)	The POEM is a validated questionnaire used to assess disease symptoms in atopic eczema patients in both clinical practice and clinical trials (30, 31). The tool consists of 7 items each addressing a specific symptom (itching, sleep, bleeding, weeping, cracking, flaking, and dryness). POEM for proxy completion is used, where the caregiver will report their perception of how often the subject has experienced each symptom over the previous week on a 5-point categorical response scale (0 = 'no days'; 1 = '1 to 2 days'; 2 = '3 to 4 days'; 3 = '5 to 6 days'; 4 = 'every day'). The total score is the sum of the 7 items (range 0 to 28) and reflects disease-related morbidity; a high score is indicative of a worse disease severity.	from Week 0-Week 68
Secondary	Change in Eczema Area and Severity Index (EASI)	The EASI is a validated measure used in clinical practice and clinical trials to assess the severity and extent of AD. The EASI is a composite index with scores ranging from 0 to 72, with higher values indicating more severe or more extensive condition.	from Week 0-Week 68
