Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This is a prospective cohort study enrolling ulcerative colitis patients who initiate tofacitinib therapy. Investigators will collect clinical data, blood and stool samples prior to initiation of tofacitinib and, at minimum, monthly after the start of therapy. They will collect tissue from colonoscopies prior to initiation of therapy and within 6 months on therapy. Clinical characteristics and response to treatment will then be associated with genotype, blood immune profiles, stool microbiota, and cellular and molecular profiles of the biopsies to generate a treatment response model. Using predictors identified in our model, we will then attempt to validate the model and findings with the OCTAVE (Pfizer), SPARC (CCF), and RISK (CCF) data.
