Abstract

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 ≤1.2). The EAIRs of malignancies (EAIR=0.7), inflammatory bowel disease (EAIR=0.1) including ulcerative colitis and Crohn's disease, depression (EAIR=1.6), and major adverse cerebro-cardiovascular events (EAIR=0.5) were low. As assessed, based on year of exposure, incidence rates were decreasing or constant over time. Conclusions In this analysis, the overall safety profile and tolerability of ixekizumab are consistent with the known safety profile in patients with PsA. No new or unexpected safety events were detected. Trial registration number NCT01695239, NCT02349295, NCT02584855, NCT03151551.
