Efficacy and Safety of a Retinoid in the Treatment of Severe Chronic Hand Eczema

Percentage Change From Baseline in Extent of Disease at End-of-treatment

The extent of disease was estimated as the percentage of hand area (with 100% defined as the palmar and dorsal aspects) affected by eczema at Baseline, and at the end of treatment). Extent of disease was estimated separately for the left and right hands, and the overall extent of disease for both hands was calculated as (Left+Right)/2. Baseline was defined at Week 0. Change from Baseline was calculated by subtracting the Baseline value from the individual post-baseline values. Percentage change from Baseline = (change from Baseline / Baseline value) \* 100.

Time frame: Baseline (Week 0) and Week 24 (end-of-treatment)

Response Duration for Responding Participants at the End-of-therapy

Response Duration was defined as time from the end-of-therapy to the first diagnosis of mild, moderate, or severe CHE. Median and inter-quartile range has been presented.

Time frame: Up to 72 Weeks (including 24 weeks of treatment and 48 weeks of follow-up)

Time to Relapse for Responding Participants at the End-of-therapy

Time to relapse was defined as the time from end-of-therapy to the first diagnosis of severe CHE. Median and inter-quartile range has been presented. The median was based on the very last participant having a follow-up period longer than expected, those explaining the high median.

Time frame: Up to 72 Weeks (including 24 weeks of treatment and 48 weeks of follow-up)

Time to Response for Responding Participants at End-of-therapy

Time to response was defined as time from start of treatment to first PGA assessment of "clear" or "almost clear". Median and inter-quartile range has been presented.

Time frame: Up to 72 Weeks (including 24 weeks of treatment and 48 weeks of follow-up)

Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs) During the Treatment Period

An AE was defined as any adverse change from the participant's Baseline (pretreatment) clinical condition, including intercurrent illness, which occurred during the course of the clinical study after written informed consent had been given, whether considered related to treatment or not. A treatment-emergent AE was defined as any adverse change that occurred after treatment started and up to 7 days after last treatment. An SAE was any experience that suggested a significant hazard, contradiction, side effect or precaution. It was any adverse event that at any dose resulted in death, was life-threatening, required in-patient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity or was a congenital anomaly/birth defect.

Time frame: Up to Week 24 (end-of-treatment)

Number of Participants Referred or Not Referred to a Psychiatrist as Per Brief Summary Inventory (BSI) 53 Questionnaire up to 24 Weeks

The BSI is a 53 item self-report scale used to measure nine primary symptom dimensions (somatization, obsessive-compulsive behavior, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation, and psychoticism). Respondents rank each feeling item (e.g., "your feelings being easily hurt") on a 5-point scale where, 0=not at all, 1=a little bit, 2=moderately, 3=quite a bit, 4=extremely (0 indicates best outcome and 4 indicates worst outcome). The total score ranged from 0 (best outcome) to 212 (worse outcome). Participants with an increase above Baseline of 25% or more on any domain subscore in BSI-53, or with an increase above Baseline of \>=2 points or a score \>=3 on any BSI-53 item that reflects depression, suicidality, psychotic symptoms, and hostility/aggression, were to be referred to a psychiatrist within 2 weeks.

Time frame: Up to Week 24

Change From Baseline in Patient Health Questionnaire (PHQ-9) Score Over 28 Weeks

The PHQ-9 was a standardized tests of mood/depression. This was a nine item measure with a response for each item between 0-3 where, 0=not at all, 1= several days, 2= more than half the days, 3= nearly every day. Total scores on this measure range from 0-27, with 0 being a minimum indicating no depressive symptoms, and 27 being the maximum number and severity of depressive symptoms. Baseline was defined at Week 0. Change from Baseline was calculated by subtracting the Baseline value from the individual post-baseline values.

Time frame: Baseline (Week 0) and Week 4, 8, 12, 16, 20, 24, 28

Number of Participants Meeting the Referral Criteria of Psychiatric Evaluation Over 28 Weeks

Participants meeting any of the following criteria were to be referred for specialist psychiatric evaluation within 2 weeks: PHQ-9 Score \>=15, Two Subsequent Scores of \>=10 and PHQ-9 Question 9 \>=1. The PHQ -9 was a standardized tests of mood/depression. This was a nine item measure with a response for each item between 0-3 where, 0=not at all, 1= several days, 2= more than half the days, 3= nearly everyday. Total scores on this measure range from 0-27, with 0 being a minimum indicating no depressive symptoms, and 27 being the maximum number and severity of depressive symptoms. Only categories with data available at the indicated time points have been presented. Categories with null values for all the arms have not been presented.

Percent Change From Baseline in Bone Mineral Density (BMD) by Dual Energy X-ray Absorptiometry (DXA) Over 72 Weeks

Bone mineral density scans of the left proximal femur (total hip) and anterior-posterior lumbar spine were obtained by use of DXA, at Baseline, at end of therapy, and 1 year (48 weeks) after end of therapy. In case of abnormality or surgery of the left hip, the right hip was to be used. If both hips were affected, the participant was not eligible for DXA. Vertebrae L1 to L4 had to be completely scanned. At least 3 vertebrae had to be free of any abnormalities potentially interfering with DXA analysis (eg, fractures, large osteophytes), otherwise the participant was not eligible for DXA. Baseline was defined at Week 0. Change from Baseline was calculated by subtracting the Baseline value from the individual post-baseline values. Percentage change from Baseline = (change from Baseline / Baseline value) \* 100. Least square means and 95% confidence interval has been presented.

Time frame: Baseline (Week 0) and Week 72
