Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a non-interventional, retrospective, and longitudinal study of participants with IBD (UC or CD) receiving vedolizumab between years 2015 and 2020. The study will determine the real-world evidence of vedolizumab, its relationship with TDM, biomarkers of inflammation, and its effect on clinical outcomes in a real-world setting.

This study will enroll approximately 5,500 participants. Participants will be enrolled in 2 cohorts: TDM Cohort and Historical Cohort. The study will have a retrospective data collection of the participants from PSP between the years 2015 and 2020. The study will include longitudinal analysis of data collected in a subset of Takeda Canada PSP, specifically for those participants on vedolizumab, some of which received biomarker testing and TDM at pre-specified intervals during their treatment.

This multi-center trial will be conducted in Canada. The overall time for data collection in the study will be approximately 5 years.

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

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
TDM Cohort: Correlation Between Week 6 Vedolizumab TDM and Week 30 Faecal Calprotectin (FCP)
Time Frame: After the first dose of vedolizumab (at Week 30)
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 Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
TDM Cohort: C-reactive Protein (CRP) Level at Week 30
Time Frame: After the first dose of vedolizumab (at Week 30)
The CRP level were detected in participant's blood 30 weeks after the participant's first dose of vedolizumab. CRP was used as a surrogate marker for disease severity, and by extension drug efficacy. This outcome measure was planned to be analyzed separately in participants with UC and CD who were collectively a part of the TDM Cohort.
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
Time Frame: After the first dose of vedolizumab (at Week 30)
Disease activity scores of CD participants were based on HBI. It consists of clinical parameters: general well-being (0 = very well to 4 = terrible), abdominal pain (0 = none to 3 = severe), number of liquid or soft stools per day, abdominal mass (0 = none to 3 = definite and tender), and complications (8 items; 1 score per item). The total score is sum of sub scores, where score <5 = remission, 5 to 7 = mild disease activity, 8 to 16 = moderate disease activity and >16 = severe disease activity. This outcome measure was planned to be analyzed only in participants with CD.
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
Time Frame: After the first dose of vedolizumab (at Week 30)
Disease activity scores of UC participants were based on Partial Mayo score. It consists of 3 sub-scores: stool pattern, most severe rectal bleeding of the day, and global assessment by physician, each graded from 0 to 3 with higher scores indicating more severe disease. These scores are summed to give a total score range of 0 to 9. Here, higher scores indicate more severe disease. This outcome measure was planned to be analyzed only in participants with UC.
After the first dose of vedolizumab (at Week 30)
Number of Participants Categorized Based on Dose Escalation
Time Frame: Baseline (Week 0) up to Week 30 (after first dose of vedolizumab)
Dose escalation was defined as a change from doses every 8 weeks to every 4 weeks.
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
Time Frame: After the first dose of vedolizumab (at Week 30)
Treatment persistence was defined as whether the participant was still on the treatment at the end of the TDM study. 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)
Treatment Duration
Time Frame: From treatment initiation up to discontinuation of treatment or up to data extraction date Oct 2020), whichever occurs first (maximum up to approximately 5 years)
Treatment duration was defined as the length of time a participant remains on treatment (i.e., from the year 2015 to 2020).
From treatment initiation up to discontinuation of treatment or up to data extraction date Oct 2020), whichever occurs first (maximum up to approximately 5 years)
