Ulcerative Colitis clinical trials at UCLA

Hyperbaric Oxygen Therapy for Ulcerative Colitis
open to eligible people ages 18-85
Chronic intestinal hypoxia and accompanying mucosal inflammation is a hallmark of ulcerative colitis (UC). Hyperbaric oxygen therapy (HBOT) involves breathing 100% oxygen under increased atmospheric pressure to increase tissue oxygenation. Two small prospective randomized controlled trials have demonstrated that the delivery of HBOT to UC patients hospitalized for acute moderate to severe flares results in improved remission rates and avoidance of in-hospital progression to biologics, small molecules, or colectomy. In this larger trial the study aims to confirm the treatment benefits of HBOT for hospitalized UC patients and study the immune-microbe mechanisms underpinning treatment response.

Prebiotics in Ulcerative Colitis
open to eligible people ages 18-85
The cause of inflammatory bowel disease (IBD) is currently unknown, although partly attributed to interactions among genetic risk polymorphisms, environmental factors, gut microbiome, and host immunity. Diet, particularly those with plant-based products, have been shown in prior research to improve gut microbial composition, which has been linked to different IBD-related outcomes. This study is interested in evaluating the impact of prebiotics on gut microbiome composition and gut health in patients with IBD. Dietary composition will be assessed at baseline and over the course of 16 weeks. Participants will be randomized to either consume an 8-week course of prebiotic supplementation beginning at week 0 or week 8. Stool samples will be collected at weeks 0 and 8. The stool will be analyzed for cross-sectional and longitudinal fecal microbial changes associated with different prebiotic and diet consumption patterns in the context of heterogeneous disease characteristics.
