E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Microscopic colitis Bile acid diarrhea |
Mikroskopisk colitis Galdesyrediarré |
|
E.1.1.1 | Medical condition in easily understood language |
Microscopic colitis is a chronic type of diarrhea with inflammation of the large colon, only seen microscopically. The causes of inflammation is unknown, but bile acids seem to play a role. |
Mikroskopisk colitis er en kronisk form for diarré med betændelse af tyktarmen, som kun kan ses ved mikroskopi. Årsagerne til betændelsen er ukendte, men galdesyre ser ud til at spille en rolle. |

E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To investigate the prevalence of bile acid diarrhea (BAD) in patients with active microscopic colitis (MC). The apperance of BAD is defined by watery stools and a raised level of 7alpha-hydroxy-4-cholesten-3-on (C4). |
|
E.2.2 | Secondary objectives of the trial |
To investigate the effect of budesonide on the bile acid homeostasis assessed by changes in C4 and FGF19 |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Suspected activity in MC, defined by Hjortswang criteria: 3 stools daily OR one watery (Bristol type 6or7) stools daily, as a mean over the last 6-7 days. Proven microscopic colitis (collagenous, lymphocytic or incomplete) in biopsies from the last 6 years |
|
E.4 | Principal exclusion criteria |
Age < 18 years Stoma Pregnancy Intestinal resection other than appendectomy cholecystectomy Other chronic intestinal disease with diarrhoea Use of other constipation agent than loperamide Systemic treatment with steroid within 2 weeks of the start of treatment Suspected or proven gastrointestinal infection Allergy to budesonide Lack of compliance or understanding of the trial If taking statin or fibrate therapy: unwilling to pause medical treatment against hypercholesterolaemia |

E.5 End points |
E.5.1 | Primary end point(s) |
Prevalence of BAD defined by fasting C4 levels > 46 ng/mL in patients with active MC |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Analysis of the biobank blood samples after LSLV. Expected aprox. medio 2022 |
|
E.5.2 | Secondary end point(s) |
Prevalence of BAD defined by total bile acids > 16 mikromol/g Effect of budesonide on Bile acid diarrhoea as defined above; comparison of prevalence of BAD week 1 and 6. Changes from week 1 (baseline), week 6 (during tratment) and week10 (after treatment) analysed with randomised mixed model: 1. Changes in biomarkers C4, FGF19, total bile acids in spot faecal sample, fractin of primary bile acids in spot faecal sample. 2. Differences between groups MC +BAD and MC - BAD in (a) total bowel movement (week 1,6,10), (b) treatment effect according to modified Hjrotswang criteria, (c) rate of relapse week 6 and 10, (d) changes in HRQol from week 1 to 6: SHS question 1 and 2 and total SHS respectively, (e) GIQLI sum of diarrhoea related questions (item 30,31,36), (f) estimated prevalence of BAD in MC calculated from the sensitivity of C4 as compared with SeHCAT. Prevalence of BAD defined by fasting FGF19 levels < 60 pg/mL in patients with active MC Prevalence of BAD in each of the MC subtypes defined by fasting C4 levels > 30 ng/mL in patients with active MC Difference in levels of C4 in week 0, 6, and 10 Difference in levels of FGF19 in week 0, 6, and 10 Correlation between difference in C4 and difference in activity Difference in groups with MC with and without BAD with regards to numbers of stools, treatment effects and quality of life index Changes in fractions of primary bile acids in stools (week 0, 6, and 10) |
