A 24 Week Trial to Compare the Efficacy and Safety of Delgocitinib Cream 20 mg/g Twice-daily With Alitretinoin Capsules Once-daily in Adult Participants With Severe Chronic Hand Eczema

Phase 3

Completed

Conditions: Chronic Hand Eczema

Interventions: Drug: Delgocitinib
Drug: Toctino

Registration Number: NCT05259722

Lead Sponsor: LEO Pharma

Brief Summary: This is a 24-week study in adult participants with severe chronic hand eczema (CHE) and with a documented inadequate response to treatment with topical corticosteroids (TCS) or for whom TCS are documented to be otherwise medically inadvisable. Eligible participants will be randomised to receive topical administration of delgocitinib cream 20 mg/g, twice-daily, or oral administration of alitretinoin capsules 30 mg (with an option to reduce to 10 mg during trial conduct), once-daily. The participants will visit the clinic regularly to have the study doctor assess their CHE and to answer questions about itch, pain, CHE symptoms, and quality of life.

The purpose of this trial is to compare the efficacy, health-related quality of life, and safety of delgocitinib cream and alitretinoin capsules.

Arm && Interventions

Group	Intervention	Description

Alitretinoin capsules 30 mg per capsule	Toctino	1 capsule per day for up to 24 weeks

Primary Outcome Measures

Name	Time	Method
Change in HECSI Score From Baseline to Week 12	12 weeks	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) with a higher score indicating greater severity.

Secondary Outcome Measures

Name	Time	Method
HECSI-90 at Week 12	12 weeks	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), with a higher score indicating greater severity. HECSI-90 is defined as at least 90% improvement in HECSI score from baseline.
IGA-CHE TS at Week 12.	12 weeks	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 global chronic hand eczema (CHE) and is based on a 5-point scale ranging from 0 (clear) to 4 (severe). IGA-CHE treatment success (IGA-CHE TS) is defined as an IGA-CHE score of 0 (clear) or 1 (almost clear) with a ≥2-step improvement from baseline.
Change in HESD Itch Score (Weekly Average) From Baseline to Week 12	12 weeks	The Hand Eczema Symptom Diary (HESD) is an eDiary in which participants will assess the worst severity of 6 individual signs and symptoms of CHE over the past 24 hours using an 11-point numeric rating scale with anchors of 0 ='no (symptom)' and 10 ='severe (symptom)' throughout the trial on a daily basis. This endpoint will only assess the 'itch' component.
Change in HESD Pain Score (Weekly Average) From Baseline to Week 12.	12 weeks	The Hand Eczema Symptom Diary (HESD) is an eDiary in which participants will assess the worst severity of 6 individual signs and symptoms of CHE over the past 24 hours using an 11-point numeric rating scale with anchors of 0 ='no (symptom)' and 10 ='severe (symptom)' throughout the trial on a daily basis. This endpoint will only assess the 'pain' component.
AUC of HECSI-90 From Baseline up to Week 24	24 weeks	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) with a higher score indicating greater severity. HECSI-90 is defined as at least 90% improvement in HECSI score from baseline. The area under the curve (AUC) at participant level will be determined as follows: 1 will be assigned when response is observed and 0 otherwise. The AUC is interpreted as number of days with 90% reduction in HECSI score until Week 24.
AUC of Change From Baseline in DLQI Score up to Week 24	24 weeks	The Dermatology Life Quality Index (DLQI) 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. The DLQI score is the sum of the 10 items (score ranging from 0 to 30); a high score is indicative of a poor quality of life. The area under the curve (AUC) at patient level will be determined from the change from baseline in DLQI score estimated as a piecewise linear function from Week 0 to Week 24. Differences will be analyzed with opposite sign to interpret positive area as improvement in scores and negative area as worsening.
Change in HECSI Score From Baseline to Week 24	24 weeks	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) with a higher score indicating greater severity.
Number of Treatment-emergent AEs From Baseline up to Week 26	26 weeks	An adverse event (AE) will be considered treatment emergent if started after the first application of investigational medicinal product (IMP), or if started before the first application of IMP and worsened in severity after first dose of IMP.
Number of Treatment-emergent SAEs From Baseline up to Week 26	26 weeks	A serious adverse event (SAE) will be considered treatment emergent if started after the first application of investigational medicinal product (IMP), or if started before the first application of IMP and worsened in severity after first dose of IMP.
Number of AEs Leading to IMP Discontinuation up to Week 24	24 weeks	The investigational medicinal product (IMP) will be discontinued permanently in case of an AE that, in the opinion of the investigator or sponsor's medical expert, contraindicates further dosing. The investigator will assess the relationship between investigational medicinal product (IMP) and the adverse event (AE).
