Summary:

      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).
