Generate Real World Data On Tofacitinib Induction Therapy and Changes In Clinical and Patient Reported Outcomes.

Terminated

• Conditions: Ulcerative Colitis
• Interventions: Other: Stool sample collection

• Registration Number: NCT05069259
• Lead Sponsor: Pfizer

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.

Detailed Description

This is a low-interventional study in which the intervention under study is home fecal calprotectin testing which falls outside of normal standard of care in ulcerative colitis. Tofacitinib is prescribed and administered as per the Swiss prescribing information. Accordingly, this study is registered on ClinicalTrials.gov as an interventional study. Under Swiss law, this study is considered and approved as a non-interventional study (Category A, Human Research Ordinance, Swiss Confederation).

The total Inflammatory Bowel Disease Questionnaire score ranges from 32 to 224. For the total score and each domain, a higher score indicates better quality of life.
Proportion of participants achieving Inflammatory Bowel Disease Questionnaire response	Week 8, Week 16	Inflammatory Bowel Disease Questionnaire response is defined as an Inflammatory Bowel Disease Questionnaire score ≥16 points higher than Inflammatory Bowel Disease Questionnaire baseline score.
