Pharmacologic Weight Loss as Adjunct Therapy for Ulcerative Colitis in Obese Patients

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 as follows 3.75-23mg x 1 week --\> 7.5-46mg x 1 week --\> 11.25-69mg x 1 week --\> 15-92mg. Patients who experience side effects would undergo slower titration, and dose would be down-titrated and capped at highest tolerated dose.

Matching placebo, titrated as active intervention
