Abstract

Background The long-term safety of anti-tumor necrosis factor (TNF) drugs is particularly important in pediatric patients (pts) who may require prolonged treatment of their inflammatory disease.

Objectives To evaluate long-term rates of serious adverse events (AE) and anti-TNF AEs of special interest in adalimumab (ADA) clinical trials in pediatric pts with polyarticular or polyarticular course juvenile idiopathic arthritis (pJIA) or enthesitis-related arthritis (ERA).

Methods Safety data from pts treated with ADA, either dosed 24 mg/m2 BSA every other week (eow) or 20 mg eow (<30 kg) to 40 mg eow (≥30 kg), in 4 clinical trials in pJIA and ERA were analyzed. Three studies in pJIA enrolled pts aged 2–17 years (yrs) treated with ADA for up to 8.5 yrs. One study enrolled pts with ERA aged 6–17 yrs who were treated with ADA for up to 52 wks in this analysis. AEs of special interest included malignancy, serious infections, tuberculosis (TB) and other opportunistic infections, and death. Events per 100 patient-years (PY) were calculated using AEs reported after first ADA dose through 70 days after last dose.

Results ADA was administered to 274 pts, representing 769.0 PY of exposure. Infections, the most common AE, occurred in ≥10% of pts. Serious infection was the most frequently reported SAE (table). One case of latent TB was reported. No malignancies, opportunistic infections, or deaths were reported. 8.4% of pts (23/274) discontinued study due to AE (range, 5.1% in age <5 yr to 9.6% in ages 5 - <12 yrs). Other than uveitis, liver events, and injection site-related AEs, no differences in AE rates were observed between age groups.(table)

Conclusions These data provide support for the long-term safety of ADA in pediatric pts aged 2–17 yrs with pJIA or ERA and demonstrate a safety profile consistent with ADA in adult pts and known information about the anti-TNF class.
