Efficacy and Safety of Budesonide Foam for Participants With Active Mild to Moderate Ulcerative Proctitis or Proctosigmoiditis

The purpose of this study is to establish the efficacy profile of rectally administered budesonide foam, as compared to an equivalent volume of rectally administered placebo foam over the same dosing schedule, in participants who present with a diagnosis of active, mild to moderate, ulcerative proctitis (UP) or ulcerative proctosigmoiditis (UPS). During the study, eligible participants will be allowed to maintain previously established oral 5-aminosalicylic acid (5-ASA) treatment at doses up to 4.8 grams/day (g/day).
