Treatment of UC With Novel Therapeutics

Treatment of Ulcerative Colitis With Novel Therapeutics

Treatment of UC With Novel Therapeutics (NCT06420375) is a Phase 2 interventional studying Ulcerative Colitis Mild and Ulcerative Colitis, sponsored by Brigham and Women's Hospital. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.

About This Trial

This study is a clinical trial being done to investigate the efficacy of drug BRS201 as a treatment in patients with active mild ulcerative colitis. Participation in this study will take 12 weeks long and the study is structured as a crossover study in which participants will take the study drug for 4 weeks and a placebo drug for 4 weeks in a randomized order in the form of an oral medication. Participation may also involve receiving an IV dose of the medication. The study will require participants to attend 7 study visits, all of which will be conducted at a study site. Participation will involve taking an oral medication twice daily, tracking the medication in a log, and getting blood drawn and giving a stool and urine sample for a few lab tests throughout the study.

What Stage of Research Is This?

Phase 2 trials evaluate whether a treatment actually works against Ulcerative Colitis Mild and continue monitoring side effects. Phase 2 enrolls larger groups (typically 100–300 patients) and produces the first real efficacy signal. A successful Phase 2 readout is what unlocks the much larger Phase 3 confirmatory trials needed for FDA approval.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

With a target enrollment of 20 participants, this is a small study — typical of early-phase research, rare-disease trials, or pilot studies designed to generate preliminary signal before a larger study is launched.
