OBJECTIVE: To assess the risk of adverse events of special interest (AEoSIs) with ustekinumab and other psoriasis treatments in a real-world setting using 2014 Psoriasis Longitudinal Assessment and Registry (PSOLAR) data. AEoSIs included malignancy (excluding nonmelanoma skin cancer), major adverse cardiovascular events (MACE), serious infection, and all-cause mortality.
METHODS: Cumulative rates of AEoSIs/100 patient-years (PY) are reported for ustekinumab, infliximab, other biologics (mostly adalimumab/etanercept), and non-biologics based on pre-specified analyses using attribution rules biased against ustekinumab. Risk factors for AEoSIs, including treatments, were determined using multivariate statistical analysis.
RESULTS: A total of 12,093 patients (40,388 PY) were enrolled in PSOLAR. Overall incidence rates were 0.68/100PY for malignancy, 0.33/100PY for MACE, 1.60/100PY for serious infection, and 0.46/100PY for mortality. Unadjusted rates of serious infection for infliximab (2.91/100PY) and other biologics (1.91/100PY) were numerically higher compared with ustekinumab (0.93/100PY). Exposure to the combined group of biologics other than ustekinumab was significantly associated with serious infection (hazard ratio=1.96, P<.001). None of the biologics was associated with increased risk of malignancy, MACE, or mortality.
LIMITATIONS: Observational data have inherent biases.
CONCLUSION: Analysis of 2014 PSOLAR data identified no increased risk of malignancy, MACE, serious infection, or mortality with ustekinumab.
