Sphingosine 1-phosphate receptor modulator

Etrasimod for Ulcerative Colitis (GLADIATOR UC Trial)

Phase 2
Waitlist Available
Research Sponsored by Arena Pharmaceuticals
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial
Must have
Moderately active UC defined as a modified Mayo score of 4 to 6 and an endoscopic score ≥ 2 and rectal bleeding score ≥ 1
Be older than 18 years old
Must not have
Diagnosis of microscopic colitis, ischemic colitis, or infectious colitis
Diagnosis of Crohn's disease or indeterminate colitis or the presence or history of a fistula consistent with Crohn's disease
Timeline
Screening 3 weeks
Treatment Varies
Follow Up up to approximately 56 weeks (52-week treatment period and 4-week follow-up period)

Summary

This trial is testing whether a medication called etrasimod, taken by mouth, is safe and effective for adults with moderately active ulcerative colitis. Ulcerative colitis is a condition where the colon becomes inflamed. Etrasimod works by helping to reduce this inflammation through its effects on the immune system.

Who is the study for?
Adults with moderately active ulcerative colitis, confirmed by recent endoscopy, can join this trial. They should have a history of UC for at least 3 months and not be hospitalized for severe UC recently. People with other types of colitis or Crohn's disease cannot participate.
What is being tested?
The study is testing if etrasimod, taken orally, helps adults with moderate ulcerative colitis compared to a placebo (a pill without the drug). Participants won't know which one they're getting as it's chosen randomly.
What are the potential side effects?
Etrasimod may cause side effects like headaches, nausea, respiratory infections and high blood pressure. Since it affects the immune system, there might also be an increased risk of infections.

Other Research
The most common treatments for Ulcerative Colitis (UC) include 5-aminosalicylates (5-ASA), glucocorticoids, immunomodulators, and biologics. 5-ASA agents, such as mesalamine, work by reducing inflammation directly in the colon. Glucocorticoids, like prednisone, suppress the overall immune response to decrease inflammation but are not suitable for long-term use due to side effects. Immunomodulators, such as azathioprine, alter the immune system to prevent ongoing inflammation. Biologics, including anti-TNF agents like infliximab, target specific components of the immune system to reduce inflammation. Etrasimod, an S1P receptor modulator, works by preventing lymphocytes from exiting lymph nodes, thereby reducing their presence in the colon and decreasing inflammation. Understanding these mechanisms helps UC patients and their doctors choose the most effective treatment tailored to their specific condition and response to therapy.
