This study focuses on patients with Inflammatory Bowel Disease, a condition that causes inflammation in the digestive tract. The study will examine whether adjusting the dose of vedolizumab, a medication that helps control inflammation, can be done more efficiently by monitoring drug levels in the blood while maintaining the same treatment benefits.
The research involves patients who have either Crohn’s Disease or Ulcerative Colitis (two types of inflammatory bowel disease) whose condition is currently stable. The medication used in this study, Entyvio, is given as an injection under the skin (subcutaneous injection). The study will compare two different approaches to giving the medication: the standard way of giving fixed doses versus adjusting the dose based on measuring drug levels in the blood.
The study will last for 48 weeks, during which participants will receive injections of the medication. The main goal is to determine if adjusting the medication dose based on blood levels can be more cost-effective than the standard dosing approach while maintaining the same treatment benefits for patients.
