AB1097 MALIGNANCIES WITH LONG-TERM USE OF IXEKIZUMAB IN ADULTS WITH PSORIASIS, PSORIATIC ARTHRITIS, OR AXIAL SPONDYLOARTHRITIS: A POST-HOC ANALYSIS OF DATA FROM 25 RANDOMIZED CLINICAL TRIALS

Background This integrated analysis examines long-term incidence rates (IRs) of malignancies in adults with psoriasis (PsO), psoriatic arthritis (PsA), or axial spondyloarthritis (axSpA) who received ≥1 dose of ixekizumab (IXE) up to 5 years (PsO) or 3 years (PsA, axSpA) in clinical trials. Objectives: Methods IRs of malignancies were assessed across 25 randomized IXE clinical trials (17 PsO, 4 PsA, 4 axSpA). Malignancy rates were analyzed for pooled studies by years of therapy, through March 2022. Exposure-adjusted IRs per 100 patient-years (PY) are reported. Results 6892 patients with PsO, 1401 patients with PsA, and 932 patients with axSpA, with a cumulative IXE exposure of 18025.7 PY for PsO, 2247.7 PY for PsA, and 2097.7 PY for axSpA were included in this analysis. The IRs of malignancies at 1-year intervals up to 5 years for patients with PsO, and up to 3 years for patients with PsA and axSpA, remained low (≤1.2/100 PY) and constant. Malignancies occurred in 141/6892 patients with PsO (IR=0.8), 15/1410 patients with PsA (IR=0.7), and 9/932 patients with axSpA (IR=0.4). Of these cases, non-melanoma skin cancer (NMSC) was reported among 55 patients with PsO (IR=0.3) and 9 patients with PsA (IR=0.4). No incidences of NMSC were reported among patients with axSpA. Conclusion IRs of treatment-emergent malignancies were low and stable among adult patients with PsO, PsA or axSpA receiving IXE treatment in clinical trials over the time periods examined.
