Background Tofacitinib is an oral, small-molecule JAK inhibitor for the treatment of ulcerative colitis (UC). Using a novel electronic reporting tool, we aimed to prospectively describe the onset of tofacitinib efficacy during induction therapy in a real-world study.
Methods Patient-reported outcome data (PROs) including the simple clinical colitis activity index (SCCAI), PRO Measurement Identification Systems (PROMIS) measures, and adverse events were collected daily for the first 14 days and at day 28 and 56. Paired t tests and P for trend were utilized to compare changes in SCCAI over time. Bivariate analyses and logistic regression models were performed to describe response (SCCAI <5) and remission (SCCAI ≤2) by clinical factors.
Results Of all included patients (n = 96), 67% had failed ≥2 biologics, and 61.5% were on concomitant steroids. Starting at day 3, PROs showed significant and persistent decline of the mean SCCAI (−1.1, P < 000.1) including significantly lower SCCAI subscores for stool frequency (−0.3; P < .003), bleeding (−0.3; P < .0002) and urgency (−0.2; P < .001). Steroid-free remission at day 14, 28, and 56 was achieved in 25%, 30.2%, and 29.2% of patients, respectively. Neither prior biologics nor endoscopic severity were independently predictive of response or remission in multivariate models. Numeric improvements in all PROMIS measures (anxiety, depression, social satisfaction) were seen through day 56. Rates of discontinuation due to adverse events were low.
In this prospective real-world study, tofacitinib resulted in a rapid and persistent improvement in UC disease activity PROs. The safety findings were consistent with the established safety profile of tofacitinib.
