Immunomodulator Strategy for Inflammatory Bowel Disease
(QUOTIENT Trial)
Trial Summary
What is the purpose of this trial?
The purpose of this study is to compare the effectiveness and safety of a strategy of switching to an alternative targeted immunomodulator (TIM) therapy to treat to a target of endoscopic remission, versus continuing index TIM in patients with inflammatory bowel disease (IBD) (Crohn's disease or ulcerative colitis \[UC\]) in symptomatic remission with moderate to severe endoscopic inflammation despite optimization of index TIM in a real-world setting.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications, but it requires that your current treatment with a targeted immunomodulator (TIM) is stable for at least 3 months before certain procedures. You may need to switch to a different TIM if you qualify for the study.
What data supports the effectiveness of the drug Vedolizumab (Entyvio) for treating inflammatory bowel disease?
Vedolizumab has been shown to be effective and safe for treating moderate to severe Crohn's disease and ulcerative colitis, with clinical trials indicating higher rates of clinical response and remission compared to placebo. It works by blocking specific immune cells from reaching the gut, reducing inflammation.12345
Is vedolizumab safe for humans?
How is the drug vedolizumab different from other treatments for inflammatory bowel disease?
Vedolizumab is unique because it specifically targets the α4β7 integrin, which helps control the movement of immune cells into the gut, reducing inflammation. Unlike other treatments that block tumor necrosis factor (TNF), vedolizumab is gut-specific, which may lower the risk of certain side effects, such as progressive multifocal leukoencephalopathy, seen with less selective treatments.23567
