Main objective

Scope: Therapy

The current study aims to investigate whether atorvastatin treatment lowers the synthesis of bile acids, measured via the well-known bile acid synthesis marker C4, in a dose-response manner in patients with moderate-severe bile acid diarrhoea.

Secondary objectives 1

  1. Additionally, we will investigate the effect of atorvastatin treatment in patients with moderate-severe BAD on symptoms, hepatobiliary markers, metabolic markers, glycaemic control markers, stool samples and safety.

Conditions and MedDRA coding

Bile acid diarrhoea

Eligibility criteria

Principal inclusion / exclusion criteria as submitted by sponsor

Inclusion criteria 1

  1. Confirmed moderate-severe bile acid diarrhoea with a SeHCAT test result of ≤ 10 %

Exclusion criteria 1

  1. History of/present hepatobiliary disorder (except for simple metabolic dysfunction-associated fatty liver disease) and/or alanine aminotransferase and/or serum aspartate aminotransferase ≥ 3 times upper limit of normal

Endpoints

Primary and secondary outcome measures (English text)

Primary endpoints 1

  1. Ratio of geometric mean concentration of 7alpha-Hydroxy-4-cholesten-3-on (C4) at the end of the 80 mg atorvastatin treatment period compared to the end of the placebo treatment period.

Secondary endpoints 3

  1. Difference in mean concentration of 7alpha-Hydroxy-4-cholesten-3-on (C4) in µg/L at the end of the 80 mg atorvastatin treatment period compared to the end of the placebo treatment period.
  2. Difference in mean daily stools during the last week of the 80 mg atorvastatin treatment period compared to the last week of the placebo treatment period as assessed by a 7-day stool diary.
  3. Difference in mean daily watery stools during the last week of the 80 mg atorvastatin treatment period compared to the last week of the placebo treatment period as assessed by the total watery (6 or 7 on the Bristol Stool Chart) stools in a 7-day stool diary
