Abstract

Background: The efficacy of adalimumab in inducing and maintaining remission in children with moderately to severely active Crohn's disease was shown in the IMAgINE 1 trial (NCT00409682). As per protocol, nonresponders or patients experiencing flare(s) on every other week (EOW) maintenance dosing could escalate to weekly dosing; we aimed to determine the therapeutic benefits of weekly dose escalation in this subpopulation. Methods: Week 52 remission and response rates were assessed in patients who escalated to weekly dosing from their previous EOW schedule, which was according to randomized treatment dose (higher dose [HD] adalimumab [≥40 kg, 40 mg EOW; <40 kg, 20 mg EOW] or lower dose [LD; ≥40 kg, 20 mg EOW; <40 kg, 10 mg EOW]). Adverse events were reported for patients remaining on EOW dosing and patients receiving weekly dosing. Results: Escalation to weekly dosing occurred in 48/95 (50.5%) patients randomized to LD and 35/93 (37.6%) patients randomized to HD adalimumab (P 0.076). Week 52 remission and response rates were 18.8% and 47.9% for patients receiving LD adalimumab weekly and 31.4% and 57.1% for patients receiving HD adalimumab weekly, respectively (LD versus HD, P 0.19 for remission; P 0.41 for response). Adverse event rates were similar for patients receiving EOW and weekly adalimumab. Conclusions: Weekly adalimumab dosing was clinically beneficial for children with Crohn's disease who experienced nonresponse or flare on EOW dosing. No increased safety risks were observed with weekly dosing.
