In plain English
What this trial is testing
This study is testing Phentermine-Topiramate (a drug) as a possible treatment. Condition(s) listed: Colitis, Ulcerative and Obesity.
Participants are assigned to groups by chance (randomized).
Some participants receive a placebo or sham for comparison.
It is blinded: participants and the study team do not know who receives what.
Phase 2 studies test whether a treatment shows signs of working, and keep checking safety, in a larger group of people with the condition.
Who can join
- Ages 18 to 80
- Any sex
Some of the main requirements, copied from the record:
- adults aged 18-80y
- BMI ≥30kg/m^2
- established diagnosis of UC based on clinical and endoscopy evidence corroborated by histopathology report
Plus 4 more requirement(s). There are also 13 reasons someone might not be able to join (exclusion criteria). Only the trial team can confirm whether you qualify.
What's involved
- About 40 participants are expected to take part.
- Start date: 2020-12-18.
- Main results expected around 2024-06-30 (estimate from the record).
- 1 study site listed (1 marked recruiting) in United States.
Main thing being measured
- Weight loss - 5% (22 weeks)
In the researchers’ words
Approximately 20-40% of patients with ulcerative colitis (UC) are obese. The investigators have demonstrated that obesity adversely impacts disease course in patients with UC, leading to higher risk of persistently active disease, surgery, hospitalization, and treatment failure, particularly in biologic-treated patients.

Questions to ask your doctor and the trial team
- Am I likely to qualify, given my health history?
- What would I have to do, and how often would I need to visit?
- Could I get a placebo? What happens to my current treatment?
- What are the possible risks and benefits?
- Are travel or other costs covered?
- What happens after the trial ends?

Interventions
- Phentermine-Topiramate (Drug)
Patients will be randomized to either once-daily, oral phentermine-topiramate 15-92mg or placebo, in a 1:1 fashion, for 22 weeks, with clinic visits with an obesity medicine specialist, for intensive counseling for diet and lifestyle intervention. All patients will be dose-titrated within the first 4 weeks, starting at phentermine-topiramate 3.75-23mg, or placebo. Dose titration will be performed … - Placebo (Drug)
Matching placebo, titrated as active intervention
