End point description |
The Investigator’s Global Assessment for chronic hand eczema© (IGA-CHE) is a 5 point scale used in clinical trials to rate the severity of the subject’s CHE from 0 (clear) to 4 (severe). Treatment success means a score of 0 (clear) or 1 (almost clear) with a ≥2 step improvement from baseline.

HECSI-90 at Week 16 | |||||||||
End point description |
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 statistical analysis used was the Bayesian method with neither a p-value nor a confidence interval to report.

End point description |
The Hand Eczema Symptom Diary© (HESD) is an instrument designed to assess severity of CHE signs and symptoms. The participants will assess the worst severity of 6 individual signs and symptoms of CHE from 0 (none) to 10 (severe) over the past 24 hours. The participants will complete the HESD on a daily basis in an eDiary.' This endpoint will only assess the 'itch' component for participants with a baseline HESD itch score (weekly average) of ≥4 points.
