Clinical Trial Summary

The purpose of this research study is to compare how well two formulations of budesonide (budesonide MMX [Cortiment] and budesonide CR [Entocort]) work for treating patients with microscopic colitis.

Description:

After being informed of the study and potential risks, patients with symptomatically active microscopic colitis who provide written informed consent will undergo a 4-week screening period to determine their eligibility for the study. At week 0, eligible patients will be randomized in a single blind manner (patients will be aware, while investigators will be blinded) in a 1:1 ratio to budesonide MMX (9mg once daily) or budesonide CR (3mg three times daily). The total treatment duration will be for 8 weeks. The primary outcome will be clinical remission, defined by the Hjortswang criteria (daily average <3 loose/watery bowel movements per 24 hours in the week preceding the final assessment (loose/watery stool consistency will be measured using the Bristol Stool Chart (types 6 and 7)).

Recruitment information / eligibility

• Enrollment: 80
• Est. completion date: December 31, 2026
• Est. primary completion date: September 1, 2026
• Accepts healthy volunteers: No
• Gender: All
• Age group: 18 Years to 80 Years

Eligibility

Inclusion Criteria:

• Male or non-pregnant, non-lactating females, 18-80 years old years of age
• Females of childbearing potential must be taking adequate contraceptive precautions (i.e., implants, injectables, hormonal intrauterine devices, combined hormonal contraceptives, having a vasectomized partner or total abstinence from heterosexual relations with no plans of becoming pregnant through insemination or in vitro fertilization) and have a negative urine pregnancy test prior to randomization.
• Active symptoms of MC defined by non-bloody, watery diarrhea or loose bowel movements for at least 12 weeks (for patients with newly diagnosed MC) or a history of clinical relapse for at least one week before randomization in patients with previously established MC, and with >=28 stools within 7 days preceding randomization, of which >=20 were watery/soft stools
• Colonoscopy or flexible sigmoidoscopy with histologically confirmed MC, defined by

signs of inflammation of the lamina propria and either:

• lymphocytic colitis: =20 IELs/100 surface epithelial cells
• collagenous colitis: subepithelial collagen band >10 micrometers in diameter
• Ability of subject to participate fully in all aspects of this clinical trial
• Written informed consent must be obtained and documented

Exclusion Criteria:

• Evidence of infectious diarrhea (proved by stool culture or colonic biopsy), diarrhea due to other organic diseases of the gastrointestinal tract including Crohn's disease, ulcerative colitis, ischemic colitis, Celiac disease (ruled out by either duodenal biopsy or serum antibodies), radiation colitis, or polyps >2cm, suspicion of drug-induced MC
• History of partial or total colonic resection
• Previous exposure to >7 days of any budesonide formulation for treatment of MC
• Unwillingness to withhold protocol-proscribed medications during the trial
• Received any of: aminosalicylates, corticosteroids (other than budesonide), immunosuppressants (including thiopurines and methotrexate), bismuth subsalicylate, cholestyramine, biological treatments, or antibiotics (except for up to a 7-day course for conditions unrelated to microscopic colitis) within 8 weeks of randomization
• Use of loperamide or diphenoxylate/atropine as an anti-diarrheal agent is not permitted during the screening period
• Serious underlying disease other than MC which in the opinion of the investigator may interfere with the subject's ability to participate fully in the study, including a

history of:

• Severe anaemia (haemoglobin < 90 g/L) or leukopenia (white blood cell count < 2.5 x 109 cells/L)
• Known infection with hepatitis B, hepatitis C, or human immunodeficiency virus not on effective anti-viral therapy
• Active malignancy
• Cirrhosis or significant hepatic or renal insufficiency
• Poorly controlled type 1 or type 2 diabetes
• Glaucoma
• History of alcohol or drug abuse which in the opinion of the investigator may interfere with the subject's ability to comply with the study procedures.
• Pregnant or lactating women
• Hypersensitivity to the active ingredient of budesonide MMX® or budesonide CR and excipients

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Clinical remission	Hjortswang criteria defines clinical remission as a daily average <3 loose/watery bowel movements per 24 hours in the week preceding the final assessment (loose/watery stool consistency will be measured using the Bristol Stool Chart (types 6 and 7)	Week 8
Secondary	Histologic remission	<20 IELs/100 surface epithelial cells and subepithelial collagen band <10 micrometers in biopsy samples and a reduction in lamina propria inflammation	Week 8
Secondary	Histologic response	50% reduction in IEL count or subepithelial collagen band thickness compared to baseline and/or a reduction in lamina propria inflammation	Week 8
Secondary	Clinical response	50% reduction in average daily stool frequency for the week prior to final assessment compared to baseline	Week 8
Secondary	Patient-reported symptom improvement	Change in the European Microscopic Colitis Activity Index (E-MCAI) and its component items, including stool frequency and consistency (stools per day, solid vs. loose stools, stools of each Bristol Stool chart consistency), stools at night, feeling of a need to pass more stools shortly after a bowel movement, urgency of defecation, leakage, and abdominal pain	Week 8
