Outcome Measures

Primary Outcomes (1)

  • TDM Cohort: Correlation Between Week 6 Vedolizumab TDM and Week 30 Faecal Calprotectin (FCP)

    The relationship between vedolizumab TDM at Week 6 and FCP levels at Week 30 were studied using univariate and multivariate logistic regression models. Multivariate analyses were performed to control for possible confounding factors such as age, sex, disease type (CD/UC), duration, prior immunomodulator/biologic therapy, vedolizumab start and end dates, vedolizumab dose, vedolizumab frequency, and albumin. FCP was used as a surrogate marker for disease severity, and by extension drug efficacy. The FCP level was detected in participant's stool 30 weeks after the participant's first dose of vedolizumab. FCP was treated as a continuous variable for correlation analysis to determine Spearman's correlation coefficient. This outcome measure was planned to be analyzed only in participants enrolled in the TDM Cohort.

    After the first dose of vedolizumab (at Week 30)

Secondary Outcomes (6)

  • TDM Cohort: C-reactive Protein (CRP) Level at Week 30

    After the first dose of vedolizumab (at Week 30)

  • TDM Cohort: Disease Score for Crohn's Disease (CD) Participants Based on Harvey-Bradshaw Index (HBI) at Week 30

    After the first dose of vedolizumab (at Week 30)

  • TDM Cohort: Disease Score for Ulcerative Colitis (UC) Participants Based on Partial Mayo Score at Week 30

    After the first dose of vedolizumab (at Week 30)

  • Number of Participants Categorized Based on Dose Escalation

    Baseline (Week 0) up to Week 30 (after first dose of vedolizumab)

  • TDM Cohort: Number of Participants Categorized Based on Treatment Persistence at the End of the TDM Study at Week 30

    After the first dose of vedolizumab (at Week 30)

  • +1 more secondary outcomes

Study Arms (2)

TDM Cohort

Participants diagnosed with inflammatory bowel disease (IBD) (UC or CD) within Takeda Canada Patient Support Program (PSP) group who received treatment with vedolizumab 300 milligram (mg), infusion, intravenously, at Weeks 0, 2, and 6, and every 8 weeks thereafter as per product Health Canada Product Monograph, or every 4 or 6 weeks thereafter as per standard clinical practice between the year 2015 to 2020 along with the biomarker testing and TDM at pre-specified intervals during their treatment were observed retrospectively.

Other: No Intervention

Historical Cohort

Participants diagnosed with IBD (UC or CD) within Takeda Canada PSP group who received treatment with vedolizumab 300 mg, infusion, intravenously, at Weeks 0, 2, and 6, and every 8 weeks thereafter as per product Health Canada Product Monograph, or every 4 or 6 weeks thereafter as per standard clinical practice between the year 2015 to 2020 but did not undergo biomarker testing or TDM during their treatment were observed retrospectively.

Other: No Intervention

Interventions

As this was an observational study, no intervention was administered.
