Background: Adalimumab (Humira ® , AbbVie Inc., North Chicago, IL, U.S.A.) is a fully human monoclonal antibody specific for tumour necrosis factor-α that is approved to treat adults with moderate-to-severe chronic plaque psoriasis. Objectives: To assess long-term safety for patients with psoriasis receiving adalimumab in clinical studies. Methods: Adalimumab safety data from adults with psoriasis who received at least one adalimumab dose in 18 clinical trials were evaluated. Adalimumab was delivered subcutaneously in all treatment regimens. Treatment-emergent adverse events (AEs) were collected from the first dose to 70 days after the last dose or cut-off date (31 December 2015). AE incidence rates were expressed as events per 100 patient-years (E/100 PYs) of adalimumab exposure. Standardized incidence ratios (SIRs) for malignancies and standardized mortality ratios (SMRs) were calculated. Results: Cumulative exposure was 5429·7 PYs in 3727 patients. Overall, there were 16 536 AEs (304·6 E/100 PYs). The most common AEs were nasopharyngitis, upper respiratory infection and headache (23·7, 12·9 and 7·9 E/100 PYs, respectively). Incidence rates for serious infections, tuberculosis and opportunistic infections were 1·8, 0·3 and 0·02 E/100 PYs, respectively. Incidence of malignancy excluding nonmelanoma skin cancer (NMSC) was 0·8 E/100 PYs [SIR 0·86, 95% confidence interval (CI) 0·58–1·23]. Incidences of NMSC and melanoma were 0·6 and 0·2 E/100 PYs, respectively. The SIR was 1·55 (95% CI 1·10–2·13) for NMSC and 3·04 (95% CI 1·11–6·62) for melanoma. The SMR was 0·34 (95% CI 0·16–0·65). Conclusions: AE rates remained stable in this analysis of patients with psoriasis receiving adalimumab; no new safety signals were identified compared with earlier analyses.
