Etrasimod for Ulcerative Colitis
(ENDEAVOUR-UC Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial examines the effectiveness of etrasimod for adults with moderate to severe ulcerative colitis. Researchers aim to observe changes in patients' symptoms after starting this treatment, which is already part of their standard care. Participants will use a mobile device to complete health questionnaires about their symptoms. The trial is open to those diagnosed with ulcerative colitis who have not previously used etrasimod and for whom their doctor recommends it. As a Phase 2 trial, this research measures the treatment's effectiveness in an initial, smaller group, offering participants a chance to contribute to important findings.
Do I have to stop taking my current medications for the trial?
Yes, you will need to stop taking certain medications. You cannot take methotrexate, thiopurines, biologics, JAK inhibitors, or other S1P receptor modulators while participating in this trial.
What is the safety track record for etrasimod?
Research has shown that etrasimod has been tested for safety in treating ulcerative colitis. In a large study, 577 participants compared etrasimod to a placebo, a pill with no active medicine. The results indicated that 25% of those taking etrasimod experienced infections, compared to 22% of those taking the placebo.
Long-term studies have also found etrasimod to be generally safe for patients. Most side effects were mild, and patients continued to respond well over time. Overall, etrasimod was well-tolerated in these studies, with no major safety concerns reported.12345Why are researchers excited about this trial?
Etrasimod is unique because it works by selectively modulating the sphingosine 1-phosphate (S1P) receptor, which is different from the typical approach of using anti-inflammatory drugs or biologics that target immune system pathways more broadly. This targeted mechanism can potentially offer a more precise way to manage moderate to severe ulcerative colitis, possibly reducing inflammation with fewer side effects. Researchers are excited because etrasimod could offer a new option for patients who don't respond well to current treatments like corticosteroids or TNF inhibitors, by providing a novel pathway to control disease symptoms.
What evidence suggests that etrasimod might be an effective treatment for ulcerative colitis?
Research has shown that etrasimod, which participants in this trial will receive, can help treat moderate to severe ulcerative colitis. In one study, 44% of patients experienced almost complete symptom relief after 52 weeks, and 56% reported significant overall improvement. Another study found that 64% of patients had nearly gone symptoms by week 12, though this number dropped to 18% by week 26. Etrasimod helps reduce symptoms like urgency and stomach pain, even when other treatments have failed. These findings suggest that etrasimod can effectively help manage ulcerative colitis symptoms.678910
