Systematic review of the real‐world evidence of adalimumab safety in psoriasis registries

: Long-term safety of adalimumab in psoriasis clinical studies has been established. The objective of this research was to review real-world evidence of adalimumab safety from registries of adult patients with psoriasis treated in clinical practice. Databases (BIOSIS Previews, Current Contents Search, Derwent Drug File, EMBASE, EMBASE Alert, EMCare, MEDLINE, SciSearch) were searched for psoriasis registries with adalimumab safety data. Eligible papers were English language manuscripts (conference abstracts excluded) from psoriasis registries presenting safety data for adult patients with psoriasis receiving adalimumab. The incidence and rate (events/100 patient-years [PY]) of adverse events (AEs), serious AEs (SAEs) and AEs of special interest are reported. Abstracts of 425 publications were screened, and 401 publications excluded (208 conference abstracts; 193 papers). Remaining manuscripts were fully screened; 14 were excluded (no adalimumab data, n = 10; no safety data, n = 2; no on-treatment data, n = 1; not English, n = 1), and 10 selected. Overall rates of AEs (4273 [22.2/100PY]) and SAEs (827 [4.3/100PY]) were reported in the ESPRIT registry (N = 6059). Rates of infections (7.7-14.7/100PY) and serious infections (<0.6-2.0/100PY) were reported in four studies. Cardiovascular-related events were reported in three studies: ≤0.1/100PY per major cardiac event in ESPRIT, <0.5/100PY major cardiac events in PsoBest and serious cardiovascular events in two patients (<1%) in DERMBIO. Malignancies were reported in three studies (any malignancy, 0.9/100PY; malignancies excluding non-melanoma skin cancer [NMSC], <0.6/100PY; NMSC, 0.6-<0.5/100PY). These findings suggest that real-world safety of adalimumab is consistent across different psoriasis registries, which supports the existing long-term safety profile of adalimumab from clinical studies.
