Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change from baseline in hand modified Total Lesion Symptom Score (mTLSS)	The mTLSS is an assessment of the severity of each of the following: erythema, scaling, lichenification/hyperkeratosis, vesicles, oedema, fissures, and pruritus/pain. Each of these are rated using a 4-point severity scale.These ratings are then added to create a total mTLSS calculated as the sum of assigned individual scores with a maximum value of 21 (most severe disease) and a minimum of 0 (no disease).	Week 16
Secondary	Change from baseline in hand modified Total Lesion Symptom Score (mTLSS)	The mTLSS is an assessment of the severity of each of the following: erythema, scaling, lichenification/hyperkeratosis, vesicles, oedema, fissures, and pruritus/pain. Each of these are rated using a 4-point severity scale.These ratings are then added to create a total mTLSS calculated as the sum of assigned individual scores with a maximum value of 21 (most severe disease) and a minimum of 0 (no disease).	Weeks 2, 4 and 12
Secondary	Reduction from baseline in hand Physician's Global Assessment (PGA)	The PGA is a global assessment of the current state of the disease and will be completed specific to the hands. It is a 5-point scale of overall disease severity by rating the particular signs and symptoms of chronic hand eczema (erythema, scaling, hyperkeratosis/lichenification, vesiculation, oedema, fissures and pruritus/pain).	Weeks 2, 4, 12 and 16
Secondary	Change from baseline in Hand Eczema Severity Index (HECSI)	The HECSI scoring system incorporates both the extent and the intensity of the disease. The total sum called the HECSI score will be calculated, varying from 0 to a maximum severity score of 360 points.	Weeks 2, 4, 12 and 16
Secondary	Change from baseline in Extent of Disease affected with moderate to severe chronic hand eczema (CHE)	The Extent of Disease will be estimated by the physician as the percentage of hand area (palmar and dorsal) affected by eczema, both hands (both surface) cumulating 100%.	Weeks 2, 4, 12 and 16
Secondary	Patient Global Assessment (PaGA) measurements	Using the PaGA chart, subjects will be asked by the investigator to grade their overall change from baseline in their CHE by selecting the description which best matches their perception of treatment effect.	Weeks 2, 4, 12 and 16
Secondary	Change from baseline in hand Dermatology Life Quality Index (DLQI)	The DLQI is a simple 10-question validated questionnaire that has been used in more than 40 different skin conditions.	Weeks 2, 4, 12 and 16
Secondary	Change from baseline in Quality of Life in Hand Eczema Questionnaire (QOLHEQ)	The QOLHEQ is a disease specific instrument, thereby only assessing impairments caused by hand eczema. The QOLHEQ total-score ranges from 0-127 points.	Weeks 2, 4, 12 and 16
Secondary	Change from baseline in pain Numerical Rating Scale (NRS)	The intensity of pain related to CHE will be recorded using a NRS. Pain intensity will be evaluated by asking subjects to assign a numerical score representing of the worst intensity over the last 24 hours of their symptoms on a scale from 0 to 10, with 0 indicating no symptoms and 10 indicating the worst imaginable symptoms.	Weeks 2, 4, 12 and 16
Secondary	Change from baseline in itch Numerical Rating Scale (NRS)	The intensity of pruritus associated with CHE will be recorded using an NRS. This will be evaluated by asking subjects to assign a numerical score between 0 and 10 corresponding to their worst itching over the past 24 hours, with 0 indicating no itch and 10 indicating worst imaginable itch.	Weeks 2, 4, 12 and 16
