Primary Outcome Measures:
  • Rate of clinical remission (<= 3 stools per day) after 8 weeks [ Time Frame: 8 weeks ]

Secondary Outcome Measures:
  • Rate of clinical remission (<= 3 stools per day) after 2 weeks [ Time Frame: 2 weeks ]
  • Time to remission
  • Impact on stool consistency (watery/soft/solid) [ Time Frame: 8 weeks ]
  • Impact on abdominal pain [ Time Frame: 8 weeks ]
  • Impact on patient's general well-being [ Time Frame: 8 weeks ]
  • Effect on histopathology [ Time Frame: 8 weeks ]
  • Severity of diarrhea [ Time Frame: 8 weeks ]
  • QoL [ Time Frame: 8 weeks ]

Enrollment: 92
Study Start Date: March 2007
Study Completion Date: August 2011
Primary Completion Date: June 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: A Drug: Budesonide
9 mg per day
Experimental: B Drug: Mesalazine
3 g per day
Placebo Comparator: C Drug: Placebo
0 g per day

Detailed Description:
This study will check the reproducibility of the results reported in trials with budesonide in patients with collagenous colitis. Efficacy of mesalazine was never tested in collagenous colitis by placebo-controlled trials. This trial will check the superiority of mesalazine over placebo using the common clinical symptom of collagenous colitis, which is chronic or recurrent non-bloody, watery diarrhea.

Ages Eligible for Study:   18 Years to 80 Years   (Adult, Senior)
Sexes Eligible for Study:   All

  • Complete colonoscopy within the last 12 weeks before baseline
  • Histologically confirmed diagnosis of collagenous colitis

Exclusion Criteria:

  • Evidence of infectious diarrhea
