Patients with an ileal pouch-anal anastomosis(IPAA; pouch) due to refractory inflammatory bowel disease and increased bowel frequency in the absence of significant pouch inflammation will be randomized to liraglutide or placebo in a prospective cross over study.
Randomized, double-blind, 2-period, placebo- controlled, crossover proof of concept study. Ten patients with increased bowel frequency defined as bowel frequency \> 8 bowel movements in 24 hours on at least 4 of 7 days/week and presence of high bowel frequency \> 4 weeks despite adequate therapy for acute pouchitis or Crohn's like disease of the pouch will be randomized to either liraglutide or placebo treatment for 6 weeks (Period 1). Subjects will be randomized 1:1 to 1 of 2 treatment sequences, liraglutide-placebo or placebo-liraglutide, and receive either liraglutide or volume-matched placebo. After a wash-out period of at least 5 days (the half-life of liraglutide is 11-12 hours, thus the minimal washout period of 5 days is equal to 10 half-life's) patients will be crossed over to the other treatment arm (Period 2). Since high bowel frequency can result in significant malaise and dehydration, patients not responding to the respective therapies in period 1 may be crossed over after 4 weeks of therapy or in period 2 can be terminated early at week 4. The rationale behind the early termination is based on 2 open-label cohorts reporting the efficacy of liraglutide or exenatide in patients with high output ileostomies (the patient group the most comparable to the pouch patient population). Glucagon-like peptide- 1 (GLP-1) receptor agonist therapy even at the lowest dose showed an almost immediate effect reducing the ostomy output after 1-3 days in most patients.Thus, patients not responding to a 4-week therapy with a GLP-1receptor agonist are highly unlikely to respond if the therapy would be continued.

Treatment will be initiated at 0.6 mg per day for one week. The patient will be instructed to increase the dose to 1.2/day and 1.8 mg /day in week 2 and in week 3, respectively. From week 3 after the start of the drug until week 6 the patient will apply 1.8 mg/day liraglutide. In case of intolerance (e.g. occurrence of refractory nausea) at a higher dose (e.g. 1.8 mg daily, the highest dose in this trial) liraglutide can be reduced to the previous level.

Mean % Reduction of Bowel Frequency in Percent of the Mean 7-day Bowel Frequency After 4 Weeks of Therapy on Liraglutide vs Placebo Compared to Baseline .
Mean percentage reduction of 7-day bowel frequency after 4 weeks of therapy on Liraglutide vs placebo compared to baseline (baseline is defined as the mean 7-day bowel frequency in a 7-day period during the screening period before week 0). Due to the cross-over design, the outcome is reported depending on randomization in treatment period 1 at week 4 and treatment period 2 at week 10 vs baseline.
Time frame: Baseline, Week 4 (treatment period 1) and week 10 (treatment period 2)
Change in the 7 Day Mean Number of Day and Night Bowel Frequency at Week 4 and 6 vs Baseline on Liraglutide vs Placebo
Bowel frequency during the day and night was recorded on a daily basis. The 7-day mean number of bowel movements during the day (from getting up until bedtime) and during the night (during sleep) at baseline and at weeks 4 and 6 on liraglutide or placebo therapy is depicted. Baseline, week 4 and week 6 (treatment period 1) and week 10 and week 12 (treatment period 2)
Time frame: Baseline, Week 4 and week 6 (treatment period 1) and week 10 and week 12 (treatment period 2)
Discontinuation of Therapy in Each Treatment Arm
Number of patients discontinuing Liraglutide therapy in treatment or placebo arm due to intolerance in treatment period 1 before week 6 or treatment period 2 before week 12
Time frame: treatment period 1 before week 6 or treatment period 2 before week 12
Mean % Reduction of Bowel Frequency in Percent of the Mean 7-day Bowel Frequency After 6 Weeks of Therapy on Liraglutide vs Placebo Compared to Baseline.
Mean percentage reduction of 7-day bowel frequency after 6 weeks of therapy on Liraglutide vs placebo compared to baseline (baseline is defined as the mean 7-day bowel frequency in a 7-day period during the screening period before week 0). Due to the cross-over design, the outcome is reported depending on randomization in treatment period 1 at week 6 or treatment period 2 at week 12 vs baseline.
