Clinical Trial 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.

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).

Eligibility

Inclusion Criteria:

• Participants must have met eligibility criteria at screening and baseline in the parent trial (DELTA 1 or DELTA 2).

Primary	Number of treatment-emergent adverse events from baseline up to Week 38		From baseline to Week 38
Secondary	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).	From baseline to Week 36
Secondary	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).	From baseline to Week 36
Secondary	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).	From baseline to Week 36
Secondary	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.	From baseline to Week 36
