Summary

This trial tests vitamin B12 and a fatty acid to reduce gut inflammation in patients with ulcerative colitis. It aims to see if these treatments can lower a specific inflammation marker in the stool.

Who is the study for?
Adults aged 18-75 with confirmed ulcerative colitis (UC) for over 3 months, having significant colon involvement and active disease as shown by calprotectin levels. They must be able to consent and can take certain UC medications like mesalamine. Excluded are those with kidney stones, imminent colectomy, C. difficile or other colitis types, recent use of specific drugs including steroids and immune modulators, uncontrolled hypertension, severe liver or kidney issues, pregnancy/breastfeeding, cancer history within 5 years, immunodeficiencies or participation in another trial recently.
What is being tested?
The study tests if hydroxocobalamin combined with butyrate can lower calprotectin levels in UC patients compared to a placebo combined with butyrate. It's a short-term pilot study where participants are randomly assigned to either the treatment or placebo group without knowing which one they receive.
What are the potential side effects?
While not specified here, potential side effects may include allergic reactions to hydroxocobalamin or gastrointestinal discomfort from butyrate. As it is a trial assessing safety too, close monitoring will occur for any unexpected adverse effects.

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
Common treatments for Ulcerative Colitis (UC) work by targeting inflammation and supporting gut health. Hydroxocobalamin, a form of Vitamin B12, may reduce inflammation by modulating the immune response and decreasing oxidative stress. Butyrate, a short-chain fatty acid, has anti-inflammatory properties and supports gut health by nourishing colonocytes and maintaining the gut barrier. These mechanisms are crucial for UC patients as they address the core issues of inflammation and gut integrity. Other treatments like aminosalicylates, corticosteroids, immunomodulators, and biologics also aim to reduce inflammation and modulate the immune system, providing comprehensive management of the disease.
