Clinical Trial Summary

The purpose of this trial is to test if delgocitinib cream is effective at treating chronic hand eczema (CHE) and what side effects it may have, in children aged 12-17. There will be a range of assessments that rate the severity and extent of CHE symptoms, general health and quality of life.

Delgocitinib is a cream that suppresses specific processes in the body's response to diseases like CHE, such as inflammation.

The trial will last up to 22 weeks and has a 1-4 week screening period, a 16 week treatment period and a 2 week follow up period. During the treatment period each child will use either delgocitinib cream or a cream vehicle twice a day. Which cream each child receives is chosen randomly by a computer. The cream vehicle is made of the same ingredients as the delgocitinib cream except for the active medical ingredient. There will be 8 visits with the trial doctor.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	IGA-CHE treatment success at Week 16	The Investigator's Global Assessment for chronic hand eczema© (IGA-CHE) is a 5 point scale used in clinical trials to rate the severity of the subject's CHE from 0 (clear) to 4 (severe). Treatment success means a score of 0 (clear) or 1 (almost clear) with a =2 step improvement from baseline.	Week 16
Secondary	HECSI-90 at Week 16	The Hand Eczema Severity Index (HECSI) is a scoring system to rate the severity of hand eczema. It gives a score from 0 (none) to 3 (severe) to 6 clinical signs of hand eczema: erythema, infiltration/papulation, vesicles, fissures, scaling, and oedema over 5 regions of the hand - fingertips, fingers [except fingertips], palm of hands, back of hands, and wrists. Each region is then assigned an area score from 0 (0%) to 4 (>75%) depending on how much is covered by lesions. For each region a region score is calculated by adding up the severity scores for the 6 clinical signs and multiplying with the area score. The HESCI score equals the sum of the 5 region scores and ranges from 0 to 360. HECSI-90 is at least 90% improvement in HECSI score from baseline	Week 16
Secondary	Reduction of HESD itch score (weekly average) of =4 points from baseline at Week 16	The Hand Eczema Symptom Diary© (HESD) is an eDiary which patients use everyday to score the worst severity of 6 individual signs and symptoms of CHE over the past 24 hours from 0 (none) to 10 (severe). This endpoint will only assess the 'itch' component for participants with a baseline HESD itch score (weekly average) of =4 points.	Week 16
Secondary	Reduction of HESD pain score (weekly average) of =4 points from baseline at Week 16	The Hand Eczema Symptom Diary© (HESD) is an eDiary which patients use everyday to score the worst severity of 6 individual signs and symptoms of CHE over the past 24 hours from 0 (none) to 10 (severe). This endpoint will only assess the 'pain' component for participants with a baseline HESD pain score (weekly average) of =4 points.	Week 16
Secondary	Reduction of HESD score (weekly average) of =4 points from baseline at Week 16	The Hand Eczema Symptom Diary© (HESD) is an eDiary which patients use everyday to score the worst severity of 6 individual signs and symptoms of CHE over the past 24 hours from 0 (none) to 10 (severe). The final HESD score is an average of these 6 individual scores. This endpoint will only assess the score for participants with a baseline HESD itch score (weekly average) of =4 points.	Week 16
Secondary	IGA-CHE treatment success at Week 2	The Investigator's Global Assessment for chronic hand eczema© (IGA-CHE) is a 5 point scale used in clinical trials to rate the severity of the subject's CHE from 0 (clear) to 4 (severe). Treatment success means a score of 0 (clear) or 1 (almost clear) with a =2 step improvement from baseline.	Week 2
Secondary	IGA-CHE treatment success at Week 4	The Investigator's Global Assessment for chronic hand eczema© (IGA-CHE) is a 5 point scale used in clinical trials to rate the severity of the subject's CHE from 0 (clear) to 4 (severe). Treatment success means a score of 0 (clear) or 1 (almost clear) with a =2 step improvement from baseline.	Week 4
Secondary	IGA-CHE treatment success at Week 8	The Investigator's Global Assessment for chronic hand eczema© (IGA-CHE) is a 5 point scale used in clinical trials to rate the severity of the subject's CHE from 0 (clear) to 4 (severe). Treatment success means a score of 0 (clear) or 1 (almost clear) with a =2 step improvement from baseline.	Week 8
Secondary	IGA-CHE treatment success at Week 12	The Investigator's Global Assessment for chronic hand eczema© (IGA-CHE) is a 5 point scale used in clinical trials to rate the severity of the subject's CHE from 0 (clear) to 4 (severe). Treatment success means a score of 0 (clear) or 1 (almost clear) with a =2 step improvement from baseline.	Week 12
Secondary	Change in cDLQI score from baseline to Week 16	The children's Dermatology Life Quality Index (cDLQI) is a validated questionnaire consisting of 10 items addressing the participant's perception of the impact of their skin disease on different aspects of their quality of life over the last week. Each question is scored from 0 (no impact) to 3 (high impact). The cDLQI score is the sum of the 10 items (score ranging from 0 to 30).	Week 16
Secondary	Number of treatment emergent AEs from baseline up to Week 18	An adverse event (AE) will be considered treatment emergent if started after the first application of treatment, or started before the first application of treatment and worsened in severity after treatment.	Week 18
