Tofacitinib for induction and maintenance therapy of Crohn's disease: results of two phase IIb randomised placebo-controlled trials

Julian Panés et al. Gut. 2017 Jun.

Abstract

Objective: Tofacitinib is an oral, small-molecule Janus kinase inhibitor that is being investigated for IBD. We evaluated the efficacy and safety of tofacitinib for induction and maintenance treatment in patients with moderate-to-severe Crohn's disease (CD).

Design: We conducted two randomised, double-blind, placebo-controlled, multicentre phase IIb studies. Adult patients with moderate-to-severe CD were randomised to receive induction treatment with placebo, tofacitinib 5 or 10 mg twice daily for 8 weeks. Those achieving clinical response-100 or remission were re-randomised to maintenance treatment with placebo, tofacitinib 5 or 10 mg twice daily for 26 weeks. Primary endpoints were clinical remission at the end of the induction study, and clinical response-100 or remission at the end of the maintenance study.

Results: 180/280 patients randomised in the induction study were enrolled in the maintenance study. At week 8 of induction, the proportion of patients with clinical remission was 43.5% and 43.0% with 5 and 10 mg twice daily, respectively, compared with 36.7% in the placebo group (p=0.325 and 0.392 for 5 and 10 mg twice daily vs placebo). At week 26 of maintenance, the proportion of patients with clinical response-100 or remission was 55.8% with tofacitinib 10 mg twice daily compared with 39.5% with tofacitinib 5 mg twice daily and 38.1% with placebo (p=0.130 for 10 mg twice daily vs placebo). Compared with placebo, the change in C-reactive protein from baseline was statistically significant (p<0.0001) with 10 mg twice daily after both induction and maintenance treatments.

Conclusions: Primary efficacy endpoints were not significantly different from placebo, although there was evidence of a minor treatment effect. No new safety signals were observed for tofacitinib.

Trial registration numbers: NCT01393626 and NCT01393899.

Study design. Patients who completed the 8-week induction study and achieved clinical response-100 (decrease in Crohn's disease activity index (CDAI) score at week 8 of at least 100 points from baseline) and/or clinical remission (CDAI <150) and met eligibility criteria, were potentially eligible to enter the 26-week maintenance study. Patients were followed up for 4 weeks after completion or early withdrawal of the induction or maintenance study. *Patients were initially randomised (3:2:2:4) to receive placebo, tofacitinib 5, 10 or 15 mg twice daily. A protocol amendment was implemented to stop enrolment in the tofacitinib 15 mg twice daily dose group after 16 patients were enrolled. BID, twice daily.
