PG - 944-950 LID - 10.1136/annrheumdis-2021-222027 [doi] AB - OBJECTIVES: Ixekizumab, a high-affinity monoclonal antibody that selectively targets interleukin 17A (IL-17A), has shown significant efficacy in the treatment of psoriatic arthritis (PsA) and sustained long-term clinical response without unexpected new safety outcome for an IL-17A inhibitor. Here, we report the updated safety profile of ixekizumab up to 3 years in patients with PsA. METHODS: This is an integrated safety analysis from four clinical trials in patients with PsA who received at least one dose of ixekizumab. Treatment-emergent adverse events (TEAEs) and selected adverse events (AEs) exposure-adjusted incidence rates (EAIRs) per 100 patient-years up to 3 years of exposure are reported. RESULTS: A total of 1401 patients with a cumulative ixekizumab exposure of 2247.7 patient-years were included in this analysis. The EAIR of patients with >/=1 TEAE was 50.3 per 100 patient-years and most TEAEs were mild to moderate in severity. Serious AEs were reported by 134 patients (EAIR=6.0). The most reported TEAEs were nasopharyngitis (EAIR=9.0) and upper respiratory tract infection (EAIR=8.3). Infections in general and injection site reactions were the most common TEAEs; the incidence rates of serious cases were low (EAIR
