Inclusion criteria

Inclusion criteria: 1. Provided written informed consent. 2. >18 years of age 3. Confirmed diagnosis of ulcerative colitis according to international guidelines (ECCO). 4. Patients with moderately-to-severely active disease, as defined as a Mayo score of 6-12, with a rectal bleeding subscore of 1 to 3. 5. Endoscopic Mayo subscore of 2-3. 6. Patients who had failure or intolerant to at least one of the following agents: oral or intravenous glucocorticoids, azathioprine, 6-mercaptopurine, infliximab, golimumab or adalimumab. 7. Because the effects of Tofacitinib on pregnancy are not fully understood, women in childbearing age have to avoid pregnancy. Therefore the above cited patients have to use a suitable contraceptive method such as diaphragm, spiral or contraceptive pill before entering the study, for its entire duration and for 15 weeks after the suspension of the aforementioned drug Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range 45 F.1.3 Elderly (>=65 years) yes F.1.3.1 Number of subjects for this age range 15
