Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Exploratory primary outcome: The prevalence and long-term variability of pruritus over 48 weeks in patients with primary sclerosing cholangitis. Pruritus is measured using the numerical rating scale (NRS), 5d itch scale and the Simple Cholestatic Complaints Score at baseline, 12, 24, 36 and 48 weeks. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. The variability and intensity of pruritus in PSC, compared with pruritus in non-cholestatic liver diseases, IBD alone and healthy participants. Pruritus is measured using the NRS and 5d itch tool at baseline, 12, 24, 36 and 48 weeks for PSC and measured at baseline and 48 weeks for non-cholestatic liver disease, and measured at baseline only for those with IBD alone and healthy participants. 2. Severity and extent of the liver disease, collected from medical records at baseline and up until 48 weeks 3. Routinely collected laboratory blood tests (full blood count, renal function, liver function tests, HbA1C and INR test results) collected during routine clinic visits from baseline up until 48 weeks 4. Exploratory biomarkers (serum bile acid levels and autotaxin activity results) collected during routine clinic visits from baseline and up until 48 weeks 5. Current use of anti-pruritic therapies and their effectiveness, collected from medical records at baseline up until 48 weeks 6. Quality of life measures measured using the Chronic Liver Disease Questionnaire CLDQ and the EQ-5D-5L tools, taken at baseline, 12, 24, 36 and 48 weeks for those with PSC, baseline and 48 weeks for those with non-cholestatic liver disease, and at baseline for those with IBD alone and healthy controls. | — |
