Clinical Trial 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).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of Participants Who Achieved Remission	Remission was a combined assessment of clinical and endoscopic variables, defined as an endoscopy score of less than or equal to (<=) 1, a rectal bleeding score of 0, and an improvement or no change from baseline in stool frequency subscales of the Modified Mayo Disease Activity Index (MMDAI) at the end of 6 weeks of treatment. MMDAI was used to assess the overall disease activity for each participant. MMDAI evaluated 4 indices: stool frequency, rectal bleeding, physician's global assessment (PGA) and endoscopy findings each on a scale of 0 to 3 with a maximum total score of 12. Stool frequency MMDAI subscore ranged from 0-3, where 0 indicated normal number of stools per day and 3 indicated 5 or more stools than normal. Rectal bleeding MMDAI subscore ranged from 0-3, where 0 indicated no blood seen and 3 indicated blood alone passed. Endoscopy MMDAI subscore ranged from 0-3, where 0 indicated normal or inactive disease and 3 indicated severe disease (spontaneous bleeding, ulceration).	Week 6
Secondary	Percentage of Participants Who Achieved a Rectal Bleeding MMDAI Subscale Score of 0 at End of Week 6	The MMDAI was used to assess the overall disease activity for each participant. The MMDAI evaluated 4 indices:stool frequency, rectal bleeding, physician's global assessment and endoscopy findings each on a scale of 0 to 3 with a maximum total score of 12. Rectal bleeding MMDAI subscore ranged from 0-3, where 0 indicated no blood seen and 3 indicated blood alone passed. Missing data was imputed using LOCF method.	Week 6
Secondary	Number of Scheduled Assessments With Rectal Bleeding Responder Classification	The MMDAI was used to assess the overall disease activity for each participant. The MMDAI evaluated 4 indices: stool frequency, rectal bleeding, PGA and endoscopy findings each on a scale of 0 to 3 with a maximum total score of 12. Rectal bleeding MMDAI subscore ranged from 0-3, where 0 indicated no blood seen and 3 indicated blood alone passed. Percentage of participants who were rectal bleeding responder at scheduled assessments were reported. Rectal bleeding responders were defined as those participants who achieved a rectal bleeding MMDAI subscale score of 0 during the treatment period. Missing data was imputed using LOCF method.	Weeks 1, 2, 4, and 6
Secondary	Percentage of Participants Who Achieved an Endoscopy MMDAI Subscale Score of 0 or 1 at End of Week 6	The MMDAI was used to assess the overall disease activity for each participant. The MMDAI evaluated 4 indices: stool frequency, rectal bleeding, physician's global assessment and endoscopy findings each on a scale of 0 to 3 with a maximum total score of 12. Endoscopy subscale ranged from 0-3, where 0 = normal or inactive disease, 1 = mild disease, 2 = moderate disease and 3 = severe disease (spontaneous bleeding, ulceration). Percentage of participants with normal or mild disease have been presented in this outcome measure. Missing data was imputed using LOCF method.	Week 6
Secondary	Percentage of Participants Who Achieved a Score of 0 for Rectal Bleeding Subscale and a Combined Score of <=2 for Bowel Frequency (BF) and Physician's Global Assessment (PGA) in the MMDAI Subscales at End of Week 6	The MMDAI was used to assess the overall disease activity for each participant. The MMDAI evaluated 4 indices: stool frequency, rectal bleeding, PGA and endoscopy findings each on a scale of 0 to 3 with a maximum total score of 12. Rectal bleeding subscore ranged from 0-3, where 0 indicated no blood seen and 3 indicated blood alone passed. BF subscore ranged from 0-3, where 0 indicated normal number of stools per day and 3 indicated 5 or more stools than normal. PGA subscore ranged from 0-3, where 0 indicated normal disease and 3 indicated severe disease. Missing data was imputed using LOCF method.	Week 6
Secondary	Percentage of Participants Who Achieved an MMDAI Total Score of <= 3 With Greater Than or Equal to (>=2) Points of Improvement From Baseline at the End of Week 6	The MMDAI was used to assess the overall disease activity for each participant. The MMDAI evaluated 4 indices: stool frequency, rectal bleeding, PGA and endoscopy findings each on a scale of 0 to 3 with a maximum total score of 12. Rectal bleeding subscore ranged from 0-3, where 0 indicated no blood seen and 3 indicated blood alone passed. BF subscore ranged from 0-3, where 0 indicated normal number of stools per day and 3 indicated 5 or more stools than normal.
