The pan-JAK inhibitor delgocitinib in a cream formulation demonstrates dose response in chronic hand eczema in a 16-week randomized phase IIb trial.

BACKGROUND: Chronic hand eczema (CHE) is a burdensome disease, and new well-documented, safe and efficacious treatments are warranted. In a recent CHE phase IIa trial, the pan-Janus kinase (JAK) inhibitor delgocitinib in an ointment formulation was found to be efficacious and well tolerated. OBJECTIVES: This trial assessed the dose response, efficacy and safety of delgocitinib cream in CHE. METHODS: In this double-blind, phase IIb dose-ranging trial, adults with CHE and a recent history of inadequate response or contraindication to topical corticosteroids were randomized to delgocitinib cream 1, 3, 8, 20 mg g-1 or vehicle treatment twice daily for 16 weeks. The primary endpoint was the Investigator's Global Assessment for CHE (IGA-CHE) treatment success [0 (clear) or 1 (almost clear) with a ≥ two-point improvement from baseline to week 16]. Secondary endpoints were the time to IGA-CHE treatment success and changes in Hand Eczema Severity Index (HECSI); other endpoints were itch and pain numerical rating scale (NRS) scores, and Patient's Global Assessment (PaGA) at week 16. RESULTS: Patients (n = 258) were randomized 1 : 1 : 1 : 1 : 1 to delgocitinib cream 1, 3, 8, 20 mg g-1 or vehicle. A significant dose-response relationship was established for IGA-CHE (P < 0.025). IGA-CHE treatment success at week 16 was achieved in 21.2% (1 mg g-1 ), 7.8% (3 mg g-1 ), 36.5% (8 mg g-1 ), 37.7% (20 mg g-1 ) and 8.0% (vehicle) of patients. Delgocitinib 8 and 20 mg g-1 showed a treatment effect against vehicle (P < 0.001). Similarly, there were improvements in HECSI, itch and pain NRS scores, and PaGA. Delgocitinib cream was well tolerated with the majority of adverse events being mild or moderate and considered unrelated to treatment. The most frequently reported adverse events were nasopharyngitis (17.3-29.4% in delgocitinib groups vs. 40% in vehicle group), eczema (5.8-11.3% in delgocitinib groups vs. 16.0% in vehicle group) and headache (3.8-11.5% in delgocitinib groups vs. 4.0% in vehicle group). CONCLUSIONS: In this trial, delgocitinib cream showed a dose-response relationship in terms of efficacy and was well tolerated.

Risk of Cardiovascular Outcomes among Psoriasis Patients Treated with Biologics and Other Systemic Agents.

BACKGROUND: The risk for cardiovascular events associated with systemic therapies for psoriasis, including biologics, is unclear. METHODS: We used administrative data from Medicare 2006 through 2011 to identify psoriasis patients who initiated systemic treatments. We estimated incidence rates of hospitalized myocardial infarction, stroke, and a composite cardiovascular disease outcome, adjusting for potentially confounding factors. RESULTS: There were 28,878 initiations of psoriasis treatments. Rates of myocardial infarction were highest for methotrexate (10.32/1000 patient-years, 95%CI 8.55-12.46) and numerically lower for biologics. Patterns were similar for stroke and the composite cardiovascular disease outcome. After multivariable adjustment, there were no significant differences between systemic therapies for any of the outcomes studied. CONCLUSIONS: In this cohort of predominantly older psoriasis patients, there was no elevated nor protective risk of cardiovascular or stroke events associated with systemic therapies for psoriasis compared to conventional treatments.
