Efficacy and safety of tofacitinib in ulcerative colitis based on prior tumor necrosis factor inhibitor failure status
Background and aims: Tofacitinib is an oral, small-molecule Janus kinase inhibitor for the treatment of ulcerative colitis. The authors summarize the efficacy and safety data of tofacitinib 5 or 10 mg twice daily in the ulcerative colitis clinical program, stratified by prior tumor necrosis factor inhibitor (TNFi) failure status.
Methods: Efficacy was assessed in the pooled phase 3 OCTAVE Induction 1 and 2 studies (n = 1139), the phase 3 OCTAVE Sustain maintenance study (n = 593), and the dose-escalation subpopulation of the open-label, long-term extension OCTAVE Open study (n = 59). Safety was assessed in OCTAVE Sustain, the dose-escalation subpopulation, and the Overall Cohort, which included patients from OCTAVE Induction 1 and 2, OCTAVE Sustain, and OCTAVE Open (n = 1124; no prior TNFi failure, n = 541; prior TNFi failure, n = 583; phase 2 data were excluded when stratified by prior TNFi failure status). The dose-escalation subpopulation received tofacitinib 10 mg twice daily in OCTAVE Induction 1 and 2, tofacitinib 5 mg twice daily in OCTAVE Sustain, and tofacitinib 10 mg twice daily in OCTAVE Open.
Results: Tofacitinib had greater efficacy than placebo, regardless of prior TNFi failure status. In OCTAVE Sustain and the Overall Cohort, herpes zoster (non-serious and serious) rates were numerically higher in tofacitinib-treated patients with versus without prior TNFi failure. Dose escalation to tofacitinib 10 mg twice daily generally recaptured clinical response for most patients. Herpes zoster (non-serious and serious) rates were numerically higher in the dose-escalation subpopulation versus the Overall Cohort.
Conclusions: Tofacitinib was efficacious in patients with ulcerative colitis regardless of prior tumor necrosis factor inhibitor (TNFi) failure status. Herpes zoster (non-serious and serious) rates were numerically higher in patients who had previously failed TNFi.
