Cohorts and Interventions

Group / Cohort	Intervention / Treatment
All Participants; Korean participants who are prescribed with Jyseleca (Filgotinib Maleate) tablet 100 mg and 200 mg per approved prescribing information of Filgotinib Maleate in the post marketing setting will be enrolled and observed for up to 24 weeks or until discontinuation of treatment due to AEs or any other reason, whichever occurs first.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Participants With Serious Adverse Events (SAEs)	A SAE is defined as any undesirable medical occurrence: resulting in death; life threatening; requiring hospitalization or extension of hospitalization; resulting in persistent or significant disability or functional impairment; resulting in congenital malformation or abnormality or other medically significant events than above mentioned criteria.	From the date of enrollment up to 24 weeks
Number of Participants With Adverse Drug Reactions (ADRs)	An ADR is defined as harmful and unintended reaction to the proper administration/use of drugs, in which a causal relationship with the drug in question cannot be ruled out. Adverse events (AEs) with unknown causality to the drug among those voluntarily reported will be also considered ADRs.	From the date of enrollment up to 24 weeks
Number of Participants With Unexpected AEs	An unexpected AE is an AE with a difference in nature, severity, specificity, or outcome, which have not been mentioned in the product licensure/safety notification of the drug.	From the date of enrollment up to 24 weeks
Number of Participants With Unexpected ADRs	Unexpected ADR is also an unexpected AE, where unexpected AE is an AE with a difference in nature, severity, specificity, or outcome, which have not been mentioned in the product licensure/safety notification of the drug.	From the date of enrollment up to 24 weeks
Number of Participants With Known ADRs	Known AEs are those listed in product licensure/notification of the drug and are also considered as known ADRs.	From the date of enrollment up to 24 weeks
Number of Participants With Non-serious AEs	Non-serious AEs are other than SAE among AEs. An AE is defined as any undesirable and unintended signs (example, abnormalities in laboratory test) or symptoms/diseases occurring during administration/use of drugs, which do not need causal relationship with relevant study drug.	From the date of enrollment up to 24 weeks
Number of Participants With Non-serious ADRs	Non-serious ADRs are other than SAE among ADR. An ADR is defined as harmful and unintended reaction to the proper administration/use of drugs, in which a causal relationship with the drug in question cannot be ruled out.	From the date of enrollment up to 24 weeks
Change From Baseline in Disease Activity Score 28 Based on C-Reactive Protein (DAS28-CRP) at Week 12 and Week 24	The DAS28 index for rheumatoid arthritis participants was a composite score of weighted components including tender joint counts of 28, swollen joint counts of 28, participant global assessment of disease activity score, and CRP value. A DAS28-CRP score of 5.1 or above =high disease activity, a value between greater than (>) 3.2 and 5.1 =moderate disease activity and value between 2.6 and 3.2 =low disease activity, value less than (<) 2.6 =disease remission.	Baseline, Week 12 and Week 24
Change From Baseline in the Mayo Clinic Score (MCS) at Week 12 and Week 24	The Mayo Clinic Score for ulcerative colitis participants is comprised of 4 parts: stool frequency, rectal bleeding, endoscopic findings, and physician's global assessment, each scored from 0 to 3, where 0=normal, 3=severe. The total score ranges from 0 to 12, with higher scores indicating increased severity of disease.	Baseline, Week 12 and Week 24
