Abstract
BACKGROUND: Psoriasis in many patients is a chronic and recalcitrant disease that requires long-term treatment, reinforcing the importance of long-term safety data. Ixekizumab, a high-affinity monoclonal antibody that selectively targets interleukin (IL)-17A, is approved for treating patients with moderate-to-severe plaque psoriasis. OBJECTIVE: To determine long-term safety of ixekizumab in psoriasis. METHODS: Integrated safety data are presented from 12-week induction period, 12-60-week maintenance period, and from all ixekizumab-treated patients from 11 clinical studies. Exposure-adjusted incidence rates (IRs) per 100 patient-years are reported. RESULTS: Overall, 5689 patients accounted for 12 061.5 patient-years of ixekizumab exposure from 11 studies. Over 156 weeks, a total of 83.9% (n = 4775) of patients reported treatment-emergent adverse events (AEs). Most opportunistic infections (IR [95% confidence interval; CI] 1.8 [1.6, 2.1]) reported were mucocutaneous candidiasis. The IR (95% CI) for oral Candida infection was 0.9 (0.8, 1.1). There was no trend of increase in IR of AEs of special interest. Serious AEs were reported in 11.8% of patients; death occurred in 0.4% (n = 23) of patients. CONCLUSION: The 3-year, long-term maintenance treatment with ixekizumab did not show any new safety signals in patients with moderate-to-severe plaque psoriasis.
