Brief Summary
This is a non-interventional, retrospective study of adult participants with IBD. IBD consists of either ulcerative colitis (UC) or Crohn's disease (CD). The study will review the clinical data previously collected during February 2007 to March 2020 of approximately 724 participants who have had treatment with adalimumab, infliximab, golimumab, or vedolizumab in Taiwan.

Outcome Measures
Primary Outcomes (9)
Percentage of Participants Who Had IBD Relapse
IBD Relapse includes re-treatment with biologics, steroid use, IBD-related hospitalization record, IBD-related ER visits, IBD-related surgery, increase in disease index. The occurrence of any of the above records will be regarded as an IBD relapse.
Up to approximately 13 years
Time to Relapse After Biologics Discontinuation
Time to relapse is defined as the time interval from end of treatment (EOT) to the first IBD relapse.
Up to approximately 13 years
Correlation Between the Clinical Variables and Relapse Post Biologics Discontinuation
The identifying predictors of relapse, survival distributions will be studied using the log-rank test for the univariate analysis and then using time dependent Cox regression models for the multivariate analysis. The potential confounders of relapse including demographics, disease status, IBD-related treatment, symptom control treatment, lab and complication will be assessed. Two predictive models will be built in the study, one is "on biologics treatment", and other is "off biologics treatment".
Up to approximately 13 years
Percentage of Participants Achieving Clinical Response
Clinical Response for CD is defined as Crohn's disease active index (CDAI) greater than or equal to (\>=) 70 points reduction from the index date. For UC, Mayo score \>=3 points reduction and \>=30 percent (%) decrease from the index date with an accompanying rectal bleeding subscore \>=1 points reduction or with absolute rectal bleeding subscore less than or equal to (\<=) 1 and as \>=2 point reduction in partial Mayo score. Index date: date when the first dose of the biologic was prescribed in each treatment cycle.
Up to approximately 13 years
Percentage of Participants Achieving Clinical Remission
Clinical Remission for CD is defined as CDAI \<=150 point.CDAI assesses CD based on clinical signs such as number of liquid stools,intensity of abdominal pain,general wellbeing,presence of comorbid conditions,antidiarrheal use,physical examination and laboratory findings.Total score ranges from 0 to 600 points.Clinical Remission for UC is defined as Mayo score \<=2 and no individual subscore \>1 and partial Mayo score \<=1.Mayo score measure disease activity of UC.Mayo score consists of 4 sub-scores: stool pattern,most severe rectal bleeding of the day,endoscopic findings,global assessment by physician,each graded from 0 to 3 with higher scores indicating more severe disease.Scores are summed to give a total score range of 0 to 12.Partial Mayo score consists of 3 sub-scores:stool pattern,most severe rectal bleeding of the day, global assessment by physician, each graded from 0 to 3 with higher scores indicating more severe disease.Scores are summed to give a total score range of 0 to 9.
Up to approximately 13 years
Percentage of Participants Achieving Steroid-free Remission
Steroid-free remission for CD is defined as CDAI \<=150 point. CDAI assesses CD based on clinical signs such as number of liquid stools, intensity of abdominal pain, general wellbeing, presence of comorbid conditions, antidiarrheal use, physical examination and laboratory findings. Total score ranges from 0 to 600 points. Steroid-free remission for UC is defined as absence of steroid treatment (within 1 week before and after the date of potential clinical remission achieved) among participants on steroids at baseline (index date). Index date: date when the first dose of the biologic was prescribed in each treatment cycle.
Up to approximately 13 years
Percentage of Participants Achieving Mucosal Healing
Mucosal healing is defined as absence of any symptom finding of ulcer or spontaneous bleeding on endoscopic assessment or Crohn's Disease Endoscopic Index of Severity (CDEIS) less than (\<) 4 for CD participants and as Mayo endoscopic subscore \<=1 for UC participants.
Up to approximately 13 years
Correlation Between the Clinical Variables and Treatment Effectiveness
The relationship between clinical variables and treatment effectiveness will be assessed. The impact of potential bias from the baseline/demographic variables, baseline matching will be performed using propensity score 1:1 matching by each treatment cycle and different types of biologic treatments before performing the comparative analysis for effectiveness outcome. The matching condition will be determined according to the data collection. IBD participants with clinical response, clinical remission, steroid-free remission, and mucosal healing will be analyzed. The difference in effectiveness between IBD participants receiving different types of biologic treatment will be compared using Chi-square test.
Up to approximately 13 years
Percentage of Participants Experiencing Infection
Participants experiencing opportunistic infections, hepatic viral infections, gastrointestinal (GI) infections, respiratory infections, respiratory failure, or sepsis or septic shock among participants receiving vedolizumab versus those receiving anti-TNF-α will be assessed.
Up to approximately 13 years
Study Arms (2)
Cohort 1: Participants With Biologics Discontinuation
Participants with IBD (UC or CD) who had received biologic treatments for at least 6 months after the initial confirmed diagnosis of IBD, and with at least 3 months follow-up period after biologics discontinuation will be observed retrospectively.
Cohort 2: Participants Treated With Biologics
Participants with IBD (UC or CD) who had any dose of biologic for IBD treatment after the initial confirmed diagnosis of IBD will be observed retrospectively.
Eligibility Criteria
Newly diagnosed IBD participants treated with biologics including vedolizumab, adalimumab, infliximab, or golimumab will be included in this study.
You may qualify if:
- Diagnosed during February 2008 to March 2020 (or per local institutional review board \[IRB\] permitted date).
- CD (International Classification of Diseases, Ninth Revision, Clinical Modification \[ICD-9-CM\]: 555.X or International Classification of Diseases, Tenth Revision, Clinical Modification \[ICD-10-CM\]: K50.XX, K50.XXX)
- UC (ICD-9-CM: 556.X or ICD-10-CM: K51.XX, K51.XXX).
- Had received any dose of biologics for IBD treatment, including vedolizumab adalimumab, infliximab or golimumab, from February 2008 to March 2020 (or per local IRB permitted date).
You may not qualify if:
- \. Participants with any suspected diagnosis of CD or UC within one year before the initial date of confirmed IBD diagnosis will be excluded.
