Popis: Background Baricitinib, a selective Janus kinase (JAK)1/JAK2 inhibitor, is approved for treatment of moderate-to-severe atopic dermatitis (AD) in adults. Objectives We report integrated baricitinib safety data in patients with up to 3.9-years exposure. Methods Three datasets from the integrated AD clinical trial program were analyzed: placebo-controlled, 2-mg–4-mg extended, and All-bari. Data cutoffs were up to 21-December-2021 for long-term extension studies. Proportions of patients with events and incidence rates (IR)/100 patient years (PY) at risk were calculated. Results 2636 patients received baricitinib for 4628.4 PY. Discontinuation due to adverse events was low (IR = 3.4). IRs in All-bari were: serious adverse events, 5.2; infection, 67.2 (any infection), 6.7 (herpes simplex), 2.8 (herpes zoster), and 0.3 (opportunistic infections). Adverse events of special interest in All-bari included seven patients with positively adjudicated major adverse cardiovascular events (MACE) (IR = 0.15), three pulmonary emboli (PE) (IR = 0.06), 14 malignancies excluding nonmelanoma skin cancer (IR = 0.3), one gastrointestinal perforation (IR = 0.02), and four deaths (IR = 0.1). No deep vein thromboses (DVT) or tuberculosis were reported. Conclusion In this analysis, baricitinib maintained a similar safety profile to earlier analyses with no new safety signals. Rates of MACE, DVT/PE, malignancies, and serious infections were within ranges of background rates in patients with AD.
