Positive topline results were announced from a second phase 3 study evaluating delgocitinib cream in adult patients with moderate to severe chronic hand eczema. 

The phase 3 DELTA 2 study (ClinicalTrials.gov Identifier: NCT04872101) compared delgocitinib cream, a topical pan-Janus kinase (JAK) inhibitor, to vehicle in patients with moderate to severe chronic hand eczema. The primary endpoint was the Investigator’s Global Assessment for chronic hand eczema (IGA-CHE) treatment success at week 16. Treatment success was defined as an IGA-CHE score of 0 (clear) or 1 (almost clear) with at least a 2-step improvement from baseline.

Compared with vehicle cream, treatment with delgocitinib cream was associated with a statistically significant improvement in chronic hand eczema at week 16. Additionally, a significantly larger proportion of patients treated with delgocitinib cream had early symptom relief compared with those treated with vehicle cream.
