BACKGROUND: Baricitinib, a selective Janus kinase 1/Janus kinase 2 inhibitor, is indicated in the European Union and Japan for the treatment of moderate-to-severe atopic dermatitis (AD) in adults who are candidates for systemic therapy.
OBJECTIVE: The objective of this study was to evaluate the safety of baricitinib 2 mg in the AD clinical program.
METHODS: Six double-blind, randomized, placebo-controlled studies, and two long-term extension studies were summarized in two datasets. Placebo comparison was based on six 16-week studies with baricitinib 2 mg. All-bari-2-mg-AD included patients who received baricitinib 2 mg at any time during the eight studies.
RESULTS: In total, 1598 patients received once-daily baricitinib 2 mg for 1434.2 patient-years of exposure (median 330 days/maximum 2.4 years). Treatment-emergent adverse events were higher for baricitinib 2 mg (57.9%) vs placebo (51.6%). Serious adverse events, serious infections, and opportunistic infections were low in frequency and similar between baricitinib 2 mg and placebo. There were no malignancies, gastrointestinal perforations, or major adverse cardiovascular events with baricitinib 2 mg in the placebo-controlled period. Herpes simplex (cluster) was higher for baricitinib 2 mg (3.8%) vs placebo (2.8%); rates decreased with extended 2 mg exposure. In All-bari-2-mg-AD, there were five malignancies other than non-melanoma skin cancer, two major adverse cardiovascular events, one peripheral venous thrombosis, one arterial thrombosis, and no pulmonary embolisms, deep vein thromboses, or deaths.
CONCLUSIONS: This integrated analysis in patients with moderate-to-severe AD confirms the established safety profile of baricitinib 2 mg. Longer exposure to treatment is required to evaluate risks of malignancies and major adverse cardiovascular events.
