Clinical Long-Term Outcomes of Patient-Reported Outcomes in the Prospective Real-World Tofacitinib Response in Ulcerative Colitis Registry

Abstract

Introduction: We previously reported the results of tofacitinib induction therapy in the prospective multi-site US real-world TOUR registry. We now assessed patient-reported outcomes (PRO’s) and predictors of success during tofacitinib maintenance therapy. Methods: TOUR included 103 patients with refractory ulcerative colitis (UC); 67% had failed ≥ 2 biologics. Patients reported the simple clinical colitis activity index (SCCAI), PRO Measurement Information Systems measures (PROMIS) for anxiety, depression, social satisfaction, and adverse events between weeks 8 and 52 using a web-based system. Paired t-tests and p for trend were utilized to compare changes in PRO measures over time. Bivariate analyses and logistic regression models were used to determine factors associated with response (SCCAI<5) or remission (SCCAI<2) at week 52. Results: Of 103 patients, 82.5% entered the maintenance phase and 43.7% remained on tofacitinib at week 52. Tofacitinib de-escalation to 5 mg BID occurred in 15% of patients. At week 52, 42.7% and 31.1% of all patients reported an SCCAI<5 and SCCAI≤2, respectively. Normalization of bowel frequency, rectal bleeding, and urgency occurred in 79%, 61%, and 48% of patients remaining on maintenance therapy. Social satisfaction improved significantly (p<0.001), while anxiety and depression scores only numerically improved. No consistent predictors for tofacitinib long-term treatment efficacy were identified, and safety findings were consistent with the known safety profile of tofacitinib. Discussion: Tofacitinib is an effective maintenance therapy in refractory UC patients. Dose reductions infrequently occurred during maintenance. Unmet needs in UC maintenance include improvement of urgency and psychosocial factors. (NCT03772145)
