Outcomes
Primary Outcome Measures
Number of treatment-emergent adverse events from baseline up to Week 38
Secondary Outcome Measures
IGA-CHE score at each scheduled visit from baseline up to Week 36
The Investigator's Global Assessment for chronic hand eczema (IGA-CHE) is an instrument used in clinical trials to rate the severity of the participant's chronic hand eczema (CHE) and is based on a 5-point scale ranging from 0 (clear) to 4 (severe).
IGA-CHE score of 0 (clear) or 1 (almost clear) at each scheduled visit from baseline up to Week 36.
The Investigator's Global Assessment for chronic hand eczema (IGA-CHE) is an instrument used in clinical trials to rate the severity of the participant's chronic hand eczema (CHE) and is based on a 5-point scale ranging from 0 (clear) to 4 (severe).
HECSI score at each scheduled visit from baseline up to Week 36
The Hand Eczema Severity Index (HECSI) is an instrument used in clinical trials to rate the severity of 6 clinical signs (erythema, infiltration/papulation, vesicles, fissures, scaling, and oedema) and the extent of the lesions in each of the 5 hand regions (fingertips, fingers [except fingertips], palm of hands, back of hands, and wrists) by use of standard scales. The HECSI score will range from 0 (lowest possible score) to 360 (highest possible score).
HECSI-75 at each scheduled visit from baseline up to Week 36
The Hand Eczema Severity Index (HECSI) is an instrument used in clinical trials to rate the severity of 6 clinical signs (erythema, infiltration/papulation, vesicles, fissures, scaling, and oedema) and the extent of the lesions in each of the 5 hand regions (fingertips, fingers [except fingertips], palm of hands, back of hands, and wrists) by use of standard scales. The HECSI score will range from 0 (lowest possible score) to 360 (highest possible score). HECSI-75 is defined as at least 75% improvement in HECSI score from parent trial baseline.
HECSI-90 at each scheduled visit from baseline up to Week 36
The Hand Eczema Severity Index (HECSI) is an instrument used in clinical trials to rate the severity of 6 clinical signs (erythema, infiltration/papulation, vesicles, fissures, scaling, and oedema) and the extent of the lesions in each of the 5 hand regions (fingertips, fingers [except fingertips], palm of hands, back of hands, and wrists) by use of standard scales. The HECSI score will range from 0 (lowest possible score) to 360 (highest possible score). HECSI-90 is defined as at least 90% improvement in HECSI score from parent trial baseline.

5. Study Description
Brief Summary
The purpose of this extension trial is to evaluate the long-term safety of delgocitinib.
Subjects will visit the clinic every 4 week to assess the safety and efficacy of the treatment, until Week 36. A final follow-up phone call is planned on Week 38.
Detailed Description
Subject who completed 16 weeks of treatment with delgocitinib cream 20 mg/g or vehicle cream twice daily in trials DELTA 1 or DELTA 2 will be offered to roll-over to this extension trial.
Subjects will be treated with delgocitinib cream 20 mg/g twice daily only if they need it to control their chronic hand eczema. In the periods when the disease is controlled, no treatment will be administered.
Clinic visits every 4 weeks are planned (with the possibility of unscheduled visits) to investigate safety and efficacy of treatment, as well as its effect on patient-reported outcomes (PROs).
