BackgroundTofacitinib, a novel, oral Janus kinase inhibitor, demonstrated a dose-dependent efficacy for induction of clinical response and remission in patients with active ulcerative colitis (UC). The objective of the current study was to determine the effect of tofacitinib on patient-reported outcomes (PROs).MethodsEligible patients (¿18 years of age) with a diagnosis of active UC (total Mayo score of 6-12 points and moderately-to-severely active disease on sigmoidoscopy) were randomized in a 2:2:2:3:3 ratio to receive oral tofacitinib 0.5 mg, 3 mg, 10 mg, or 15 mg, or placebo twice daily (BID) for 8 weeks. PROs were assessed by the Inflammatory Bowel Disease Questionnaire (IBDQ) and the Inflammatory Bowel Disease Patient-Reported Treatment Impact (IBD PRTI) survey.ResultsAt Week 8, mean IBDQ total scores had improved relative to baseline across all five treatment groups (baseline range 123.2-134.5; Week 8 range 149.6-175.4). Improvement from baseline was significantly greater (P¿=¿0.001) for tofacitinib 15 mg BID versus placebo. For tofacitinib 15 mg BID, most patients reported satisfaction or extreme satisfaction, definite preference for tofacitinib, and definite willingness to use tofacitinib again on the IBD PRTI at week 8. Patients achieving endoscopic remission (Mayo endoscopy score of 0) had significantly higher IBDQ scores and favorable PRTI scores than those not achieving endoscopic remission.ConclusionsShort-term treatment with tofacitinib BID was associated with dose-dependent improvement in health-related quality of life and patient preferences for tofacitinib. The results complement previously reported efficacy and safety data for the Phase II study. (NCT 00787202, November 6, 2008).
