As required for new medications approved by the Ministry of Food and Drug Safety, safety and efficacy information should be provided for a minimum of 90 patients treated in the setting of routine practice during 4 years following approval (until 19 September 2022). Out of all the enrolled patients, at least 18 cases (20%) will be followed up until the 52nd week to see the long term safety of Xeljanz.
This is an open-label, non-comparative, non-interventional, prospective, and multi-center study conducted in Korean health care centers by accredited physicians (ie, investigators). The study population will be adult patients with moderately to severely active UC who have had an inadequate response or intolerance to the basic treatments or biological agents. Clinical Severity of Ulcerative Colitis is classified as mild, moderate, or severe based on the Mayo score or partial Mayo score. Xeljanz will be administered according to the "Dosage and Administration" of the approved labeling. There is no visit or activity mandated by this study. The investigator will collect patient data and record the information on each patient's case report form (CRF).

Percentage of Participants With Adverse Events, Adverse Drug Reactions, Serious Adverse Events and Serious Adverse Drug Reactions
An adverse event (AE) was any untoward medical occurrence in a participant administered a medicinal product which need not necessarily have causal relationship with product treatment or usage. Serious adverse event was any adverse event that resulted in any of the following outcomes or deemed significant for any other reason: death; life-threatening; initial or prolonged inpatient hospitalization; persistent or significant disability/incapacity; congenital anomaly. Adverse drug reaction (ADR) was any untoward medical occurrence attributed to Xeljanz. Serious ADR: any ADR resulting in any of following outcomes or deemed significant for any other reason: death; life-threatening; initial or prolonged inpatient hospitalization; persistent or significant disability/incapacity; congenital anomaly. 95% confidence interval (CI) was based on Clopper-Pearson method.
