Novel JAK Inhibitor Improves QOL in Chronic Hand Eczema

TOPLINE:

Treatment with delgocitinib cream, a topical pan-Janus kinase inhibitor, resulted in a significant improvement in health-related quality of life in patients with moderate to severe chronic hand eczema (CHE), with those receiving delgocitinib cream 2src mg/g showed greater improvements in quality-of-life measures than those receiving vehicle cream over 16 weeks.

METHODOLOGY:

• This phase 2b, randomised, double-blind, five-arm, cream vehicle-controlled clinical trial evaluated the efficacy and safety of topical delgocitinib cream in 3src5 participants from November 2src18 through April 2src2src.
• Participants with mild to severe CHE and an inadequate response to topical corticosteroids, or for whom topical corticosteroids were medically inadvisable, received delgocitinib cream or vehicle cream for 16 weeks.
• The primary endpoint was the Investigator’s Global Assessment for CHE treatment success. This study evaluated patient-reported outcomes (PROs) in patients with mild and moderate to severe CHE at screening and the impact of delgocitinib on PROs in patients with moderate to severe CHE.
• PROs were collected using the Dermatology Life Quality Index (DLQI), EuroQOL-5 Dimensions-5 Levels (EQ-5D-5L), and Hand Eczema Impact Scale (HEIS) at screening, baseline, and weeks 1, 4, 8, 12, and 16.

TAKEAWAY:

• Mean DLQI, EQ-5D-5L, and HEIS scores were 8.1, src.788, and 1.7, respectively, for participants with mild CHE (n =93) and 12.1, src.689, and 2.3, respectively, for those with moderate to severe CHE (n=2src2).
• Participants with moderate to severe CHE who received delgocitinib cream 2src mg/g (n=41) showed a greater improvement in DLQI scores than those who received vehicle cream (n=38) (least squares mean difference [LSMD], −2.5; P <.src5).
• A superior improvement in EQ-5D-5L index scores was observed with delgocitinib vs vehicle cream (LSMD, src.132; P <.src1).
• Similarly, HEIS total scores were higher with delgocitinib cream than with vehicle cream (LSMD, −src.7; P <.src1).

IN PRACTICE:

“The findings of the present study demonstrate that CHE is associated with a high patient burden, particularly for those patients with moderate to severe CHE. Furthermore, the results suggest that delgocitinib cream can potentially provide a new treatment option in a disease where there is a high unmet patient need,” the authors wrote.

LIMITATIONS:

Participants included at screening may not be representative of patients under standard care in clinical practice. The analysis of delgocitinib cream included only a limited number of participants with moderate to severe CHE. Additionally, as this was a multinational study, cultural and country-specific differences may have affected patient responses, with samples being too small to investigate potential differences between countries.
