| Change from baseline in Dermatology Life Quality Index (DLQI) score | Up to Week 32 | The DLQI is a simple, 10 question (Q) validated quality-of-life questionnaire to measure how much the skin problem has affected the participant. It covers 6 domains including symptoms and feelings (Q1 and Q2), daily activities (Q3 and Q4), leisure (Q5 and Q6), work and school (Q7), personal relationships (Q8 and Q9), and treatment(Q10). The recall Period of this scale is over the last week. Response categories include 0-not at all, 1-a little, 2-a lot, and 3-very much, and unanswered or not relevant responses scored as 0. Scores range from 0 (no impact on participant's life) to 30 (extremely large effect on participant's life), and a 4-point change from Baseline is considered as the minimal clinically important difference threshold. A negative change from Baseline indicates less impact of the skin problem on participant's life. |
| Change from baseline in EQ-5D-5L score | Up to Week 32 | EQ-5D-5L is a is a validated, self-administered, generic, utility questionnaire wherein participants will rate their current health state based on the following criteria: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. |

The QOLHEQ is a disease specific instrument, thereby only assessing impairments caused by hand eczema. It consists out of 30 items which can be summarized according to four domains of HRQOL: Impairments because of (1) symptoms, (2) emotions, (3) limitations in functioning or (4) because of treatment and prevention. |
| Change from baseline in Working Limitations Questionnaire (WLQ) score | Up to Week 32 | The Work Limitations Questionnaire (WLQ) is a patient self-rated scale designed to assess on the-job impact of chronic health problems and/or treatment. The WLQ consists of 25 items in 4 dimensions: limitations handling time (5 items), physical work demands (6 items), mental interpersonal work demands (9 items), and output demands (5 items). Each item is rated on a 5- point scale from All of the Time (score 5) to None of the Time (score 0), or Does Not Apply to My Job. The WLQ Productivity Loss Score is derived from the Global Productivity Index, which is calculated as a weighed sum of the 4 dimensions. Reduction in WLQ Productivity Loss score indicates less work limitation and represents the estimated percentage of productivity loss in the past two weeks due to presenteeism relative to a healthy benchmark sample. WLQ Productivity Loss Score ranges from 0% to 24.9%. Higher percent productivity loss reflects more severe work limitations. |
| Change from baseline in Work Productivity and Activity Impairment Questionnaire Specific Health Problem v2.0 in Chronic Hand Eczema (WPAI-SHP-CHE) | Up to week 32, followed by 30 days follow-up. | The WPAI:SHP questionnaire assesses both work productivity through absenteeism (i.e., work time missed), presenteeism (i.e., impairment at work or reduced on-the-job effectiveness), and work productivity loss, as well as daily activity impairment (e.g., work around the house, shopping, exercising, childcare, studying) attributable to excess weight. Results of WPAI are expressed as a percentage of impairment from 0 to 100, with higher percentages indicating greater impairment and less productivity. Negative numbers indicate improvement from baseline. |
| Number of Participants with Treatment Emergent Adverse Events (TEAE) | Up to 40 weeks | Defined as any adverse event either reported for the first time or worsening of a pre-existing event after first dose of study drug. |
| Percentage of participants with HECSI-90 | Weeks 2, 8, 16, 32 | 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. |
