ABSTRACT
BACKGROUND:
Tofacitinib has recently been approved for treatment of moderate-to-severe ulcerative colitis (UC) in adults, yet pediatric data are limited. This international multicenter study describes the effectiveness and safety of tofacitinib in pediatric UC.METHODS:
This is a retrospective review of children diagnosed with UC treated with tofacitinib from 16 pediatric centers internationally. The primary outcome was week 8 corticosteroid-free clinical remission (Pediatric Ulcerative Colitis Activity Index <10). Secondary outcomes were clinical response (≥20-point decrease in Pediatric Ulcerative Colitis Activity Index) at week 8, corticosteroid-free clinical remission at week 24, and colectomy rate and adverse safety events through to last follow-up. The primary outcome was calculated by the intention-to-treat principle.RESULTS:
We included 101 children with a mean age at diagnosis of 12.8â ±â 2.8 years and a median disease duration of 20 months (interquartile range [IQR], 10-39 months). All had treatment failure with at least 1 biologic agent, and 36 (36%) had treatment failure with 3 agents. Median follow-up was 24 weeks (IQR, 16-54 weeks). Sixteen (16%) children achieved corticosteroid-free clinical remission at week 8, and an additional 30 (30%) demonstrated clinical response. Twenty (23%) of 88 children achieved corticosteroid-free clinical remission at week 24. A total of 25 (25%) children underwent colectomy by median 86 days (IQR, 36-130 days). No serious drug-related adverse events were reported; there was 1 case of herpes zoster and 2 cases of minor blood test perturbations.CONCLUSIONS:
In this largest real-life pediatric cohort to date, tofacitinib was effective in at least 16% of patients with highly refractory UC by week 8. Adverse events were minor and largely consistent with adult data.
Tofacitinib, widely reported in adult ulcerative colitis, has very limited pediatric data. This international collaboration is the largest pediatric study on the efficacy and safety of tofacitinib to date, providing important supportive data to clinicians and regulators.
