About this study
Official title: Prospective, Non-interventional, Observational Study in Patients With IBD Receiving IV or SC Vedolizumab Therapy to Observe Route of Administration Choices and Outcomes (VARIETY-Switzerland)
Vedolizumab is a medicine that helps to reduce sensitivity and pain in the digestive system for participants with UC or CD.
In this study, adults with UC or CD will be treated with vedolizumab according to their clinic's standard practice. Participants will receive vedolizumab as either an infusion or an injection just under the skin (subcutaneous). The main aim of the study is to observe real-world treatment patterns in participants treated with vedolizumab.
The study sponsor will not be involved in how participants are treated but will provide instructions on how the clinics will record what happens during the study.
Read the detailed description
This is a non-interventional, prospective study of participants with moderately to severely active IBD (UC or CD) who are initiating or currently ongoing induction or maintenance treatment with vedolizumab in the real world setting.
The study will enroll approximately 100 participants. The data will be collected prospectively at the study sites and will be recorded into electronic case report forms (e-CRFs). All the participants will be assigned to a single observational cohort:
- Participants with IBD
This multi-center study will be conducted in Switzerland at specialized gastroenterology centers. The overall duration of the study will be 24 months (104 weeks). Data will be collected at baseline, at 3 months (12 weeks) after induction, and every 6 months (24 weeks) after that, and at the time of switch, discontinuation and/or at routine follow-up visits up to 12 months (48 weeks).
