Study Stopped
Study was terminated due to difficulty in enrolling targeted number of participants. There were no safety and/or efficacy concerns in the decision to stop enrollment.
Generate Real World Data On Tofacitinib Induction Therapy and Changes In Clinical and Patient Reported Outcomes.
KIC-START
A LOW-INTERVENTIONAL, PROSPECTIVE, MULTI-CENTER STUDY TO EVALUATE REAL-WORLD CLINICAL, BIOCHEMICAL AND PATIENT-REPORTED RESPONSES TO TOFACITINIB INDUCTION THERAPY IN PATIENTS WITH MODERATELY TO SEVERELY ACTIVE ULCERATIVE COLITIS IN SWITZERLAND

Brief Summary
This study is expected to contribute to the body of real-world data of tofacitinib's safety and efficacy profile in ulcerative colitis. Conventional clinical outcomes will give a better understanding of response and remission rates in a representative, post-marketing population. Regular patient questionnaires and measurement of a biomarker of gut inflammation will provide detail on how patients experience induction treatment and contextualise the efficacy data.

Outcome Measures
Primary Outcomes (1)
Percentage of Participants Who Achieved Clinical Response at Week 8
Clinical response was defined as a reduction in the partial Mayo score (PMS) from baseline of \>=2 points or achieving clinical remission. Clinical remission was defined as PMS of \<= 2 with no subscore \>1. PMS consisted of 3 components: rectal bleeding, stool frequency, and physician global assessment of disease activity. Each sub score ranged from 0 (normal) to 3 (extreme severity). These sub scores were summed up to give a total score range of 0 (normal) to 9 (extreme severity), where higher scores indicated more disease severity.
