A Study to Observe the Safety and Efficacy of Vedolizumab in Biologically Naive Participants With Ulcerative Colitis (UC) or Crohn´s Disease (CD) (CHRONOS)

CHRONOS - A Multicenter, Non - Interventional Study to Observe the Safety and Efficacy of Vedolizumab (Entyvio) in Patients With Ulcerative Colitis or Crohn´s Disease That Are Biologic naïve, Observed in Daily Practice in Austria

The purpose of this non-interventional study (NIS) study is to assess further knowledge on the routine use of Entyvio in inflammatory bowel disease therapy, particularly the use in participants with CD and UC naive to biologics.

Study Overview

• Status: Completed
• Conditions: Inflammatory Bowel Diseases; Crohn Disease; Colitis, Ulcerative

Detailed Description

The drug being tested in this prospective, observational study is called vedolizumab. Vedolizumab (Entyvio) is being used to treat people who have CD or UC. This study will look in the routine use of vedolizumab in inflammatory bowel disease therapy in participants with CD or UC who did not receive a biologic treatment before. The study will enroll approximately 150 participants. All participants enrolled in this will belong to one observational group: Vedolizumab.

Participants taking vedolizumab as per physician's prescription in routine clinical practice will be observed.

This multi-centre trial will be conducted in Austria. The overall time to participate in this study is 2 years. Participant taking vedolizumab in routine clinical practice will make multiple visits to the clinic at Baseline, Week 20 and 52. Once a participant is switched to subsequent biologic treatment upon failing treatment with vedolizumab, the switching date will be considered as new baseline followed by visits at Week 20 and 52.

Cohorts and Interventions

Group / Cohort
Vedolizumab; Bio-naïve participants with UC or CD will be treated with vedolizumab as per local prescriptions from physician in routine medical practice for up to 52 Week. Participants who fail on vedolizumab may be switched during the study to another biologic treatment as prescribed by the physician during routine medical practice for up to 52 Weeks.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Percentage of Participants With UC Achieving Clinical Response Based on Partial Mayo Score	Clinical response is defined as a decrease in the partial Mayo Score of at least 2 points and >=25% from baseline, with an accompanying decrease in rectal bleeding subscore of >=1 point from baseline or absolute rectal bleeding subscore of <=1 point. Mayo score is an instrument designed to measure disease activity of UC. It consists of 3 subscores: stool frequency, rectal bleeding, and physician rating of disease activity, 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; where higher scores indicating more severe disease. Outcome measure is planned to be assessed in bio-naive participants who receive vedolizumab treatment.	Baseline up to 52 Weeks
Percentage of Participants With CD Achieving Clinical Response Based on Harvey-Bradshaw Index (HBI)	Clinical response is defined as a decrease in HBI score of >=3 points from baseline. HBI score is used to measure the disease activity of CD. It consists of clinical parameters: general well-being (0-4, where higher score means lower well being), abdominal pain (0-3, higher score means more severe pain), number of liquid stools per day, abdominal mass (0-3, where higher score means presence of swelling in the abdomen), and complications (score 1 per item). Total score is the sum of individual parameters. The score ranges from a minimum score of 0 to no pre-specified maximum score as it depends on the number of liquid stools, where higher scores indicating more severe disease.	Baseline up to 52 Weeks
Number of Bio-naïve Participants Reporting One or More Treatment-emergent Adverse Events		Baseline up to 52 Weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Percentage of Participants With UC Achieving Clinical Remission Based on Partial Mayo Score	Clinical remission is defined as a partial Mayo score of <=2 with no individual subscore >1. Mayo score is an instrument designed to measure disease activity of UC. It consists of 3 subscores: stool frequency, rectal bleeding, and physician rating of disease activity, 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; where higher scores indicating more severe disease. Outcome measure is planned to be assessed in participants who failed on vedolizumab during the first 52 weeks and will switch to another biological therapy up to 52 weeks.	up to 52 weeks from start of another biological therapy
Percentage of Participants With CD Achieving Clinical Remission Based on Harvey-Bradshaw Index (HBI)	Clinical remission is defined as total HBI score of <=4 points. HBI score is used to measure the disease activity of CD. It consists of clinical parameters: general well-being (0-4, where higher score means lower well being), abdominal pain (0-3, higher score means more severe pain), number of liquid stools per day, abdominal mass (0-3, where higher score means presence of swelling in the abdomen), and complications (score 1 per item). Total score is the sum of individual parameters. The score ranges from a minimum score of 0 to no pre-specified maximum score as it depends on the number of liquid stools, where higher scores indicating more severe disease. Outcome measure is planned to be assessed in participants who failed on vedolizumab during the first 52 weeks and will switch to another biological therapy up to 52 weeks.	up to 52 weeks from start of another biological therapy
Percentage of Participants With UC Achieving Durable Clinical Response Based on Partial Mayo Score	Durable clinical response is defined as clinical response at Week 104, where clinical response is defined as a decrease in the partial Mayo Score of at least 2 points and >=25% from baseline, with an accompanying decrease in rectal bleeding subscore of >=1 point from baseline or absolute rectal bleeding subscore of <=1 point. Mayo score is an instrument designed to measure disease activity of UC. It consists of 3 subscores: stool frequency, rectal bleeding, and physician rating of disease activity, 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; where higher scores indicating more severe disease. Outcome measure is planned to be assessed in participants who failed on vedolizumab during the first 52 weeks and will switch to another biological therapy up to 52 weeks.	up to 52 weeks from start of another biological therapy
Percentage of Participants With CD Achieving Durable Clinical Response Based on Harvey-Bradshaw Index (HBI)	Durable clinical response is defined as clinical response at Week 104, where clinical response is defined as a decrease in HBI score of >=3 points from baseline. HBI score is used to measure the disease activity of CD. It consists of clinical parameters: general well-being (0-4, where higher score means lower well being), abdominal pain (0-3, higher score means more severe pain), number of liquid stools per day, abdominal mass (0-3, where higher score means presence of swelling in the abdomen), and complications (score 1 per item). Total score is the sum of individual parameters. The score ranges from a minimum score of 0 to no pre-specified maximum score as it depends on the number of liquid stools, where higher scores indicating more severe disease. Outcome measure is planned to be assessed in participants who failed on vedolizumab during the first 52 weeks and will switch to another biological therapy up to 52 weeks.	up to 52 weeks from start of another biological therapy
Number of Participants who Failed Vedolizumab Therapy Reporting One or More Treatment-emergent Adverse Events		up to 52 weeks from start of another biological therapy
