Background/Aims 
Pooled safety data have been reported with secukinumab in patients with psoriatic arthritis (PsA), ankylosing spondylitis (AS) and psoriasis (PsO). Here we report longterm safety data for secukinumab in patients with PsA, AS or PsO up to 5 years.
Methods 
The integrated clinical trial safety dataset included data pooled from 28 randomised controlled clinical trials of secukinumab 300, 150 or 75 mg in PsO (11 Phase 3 and 8 Phase 4 trials), PsA (5 Phase 3 trials) and AS (4 Phase 3 trials), along with post-marketing safety surveillance data starting 26 December 2014, with a cut-off date of 25 December 2018. Adverse events were reported as exposure-adjusted incident rates (EAIRs) per 100 patient-years. Analyses included all patients who received ≥1 dose of secukinumab.
Results 
A total of 12,637 patients (8,819, 2,678 and 1,140 patients with PsO, PsA and AS, with an exposure of 15,063.1, 5,984.6 and 3,527.2 patient-years, respectively) were included. The most frequent adverse event was upper respiratory tract infection and the EAIR per 100 patient-years for inflammatory bowel disease (IBD), malignancies and major adverse cardiac events (MACE) remained low. The EAIR per 100 patient-years for adverse events of special interest are reported in Table 1. The cumulative post-marketing exposure to secukinumab was estimated to be ∼285,811 patient-years across the approved indications. Post-marketing safety data showed cumulative reporting rates of 1.4, 0.3, 0.2 and 0.2 patienttreatment years for serious infections, malignancy, total IBD and MACE, respectively.
Conclusion 
Secukinumab was well tolerated in this long-term analysis of patients with PsO, PsA and AS across clinical trials and post-marketing surveillance, with a safety profile consistent with previous reports (Deodhar, 2019).
