Description
Inclusion Criteria:
Diagnosis of primary sclerosing cholangitis (PSC) established by all of the following criteria:
- Alkaline phosphatase >1.5x upper limit of normal for at least 6 months prior to study enrollment
- Cholangiography demonstrating intrahepatic and/or extrahepatic biliary dilation, beading, and/or strictures consistent with PSC
- Liver histology (if available for review) consistent with or diagnostic of PSC
- Women of child-bearing potential willing to use birth control for the duration of the study.
Exclusion Criteria:
- Treatment with any investigational agents within three months prior to or during the study
- Treatment with systemic antibiotics, azulfidine, systemic corticosteroids, colchicine, methotrexate, azathioprine, cyclosporine, chlorambucil, budesonide, pentoxifylline, tacrolimus, or vitamin E within three months prior to or during the study.
- Concomitant treatment with NSAIDS, antiplatelet agents, antihyperlipidemics, and anticoagulant warfarin.
- Anticipated need for liver transplant within one year as determined by Mayo PSC risk score (<80% one-year survival without transplant)
- Active drug or alcohol use
- Findings suggestive of liver disease of an alternative or concomitant etiology, such as chronic alcoholic liver disease, chronic hepatitis B or C infection, hemochromatosis, Wilson's disease, α1-antitrypsin deficiency, non-alcoholic steatohepatitis, primary biliary cirrhosis, or secondary sclerosing cholangitis (e.g., post-liver transplantation biliary stricture)
- Pregnancy or lactation
- Any condition that, in the opinion of the investigator, would interfere with the patient's ability to complete the study safely or successfully.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in Serum Alkaline Phosphatase (SAP)
Time Frame: baseline, 12 weeks
|
Number of subjects who experience a reduction of Serum Alkaline Phosphatase (SAP) to less than 1.5 x Upper Limit of Normal or a 40% reduction between baseline and week 12.
|
baseline, 12 weeks
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in Serum Aspartate Aminotransferase (AST)
Time Frame: Baseline, 12 weeks
|
AST is an enzyme found in high amounts in liver, heart, and muscle cells.
This test is mainly done along with other tests such as alkaline phosphatase and bilirubin to diagnose and monitor liver disease.
This test evaluates hepatocyte integrity, as serum levels of this enzyme rise in response to a variety of forms of injury to hepatic cells.
The normal range is 10 to 40 Unit/Liter (U/L)
|
Baseline, 12 weeks
|
Change in Total Bilirubin
Time Frame: Baseline, 12 weeks
|
Bilirubin is a yellowish pigment found in bile, a fluid made by the liver.
A small amount of older red blood cells are replaced by new blood cells every day.
Bilirubin is left after these older blood cells are removed.
The liver helps break down bilirubin so that it can be removed from the body in the stool.
The normal range for total bilirubin is 0.3 to 1.9 milligrams/deciliter (mg/dL)
|
Baseline, 12 weeks
|
Change in C-Reactive Protein (CRP)
Time Frame: Baseline, 12 weeks
|
C-reactive protein is a substance produced by the liver in response to inflammation.
Normal CRP levels are below 3.0 milligrams/Liter (mg/L)
|
Baseline, 12 weeks
|
Change in Mayo Primary Sclerosing Cholangitis (PSC) Risk Score
Time Frame: Baseline, 12 weeks
|
The Mayo Risk Score (R) = (0.0295 * (age in years)) + (0.5373 * natural logarithm(total bilirubin in mg/dL)) - (0.8389 * (serum albumin in g/dL)) + (0.5380 * natural logarithm(AST in IU/L) + (1.2426 * (points for variceal bleeding)) where: AST = serum aspartate aminotransferase level, Points for variceal bleeding: 0 if none, 1 if present. Each unit increase in the Mayo Risk Score (R) is associated with a 2.5-fold increase in the risk of death. Most references to the score round the coefficients to 2 decimal places. The score shows very slight upward slope over time in stable patients, but during the terminal phase it shows an acceleration in progression. |
Baseline, 12 weeks
|
Change in Fatigue Severity
Time Frame: Baseline, 12 weeks
|
Fatigue will be measured by a Modified Fatigue Impact Scale (MFIS).
This instrument provides an assessment of the effects of fatigue in terms of physical, cognitive, and psychosocial functioning.
The full-length MFIS consists of 21 items.
Subjects rate on a 5-point scale with 0 = never to 4 = almost always.
The total score for the MFIS is the sum of the scores for the 21 items ranging from score of 0-84.
Higher numbers indicate greater fatigue.
|
Baseline, 12 weeks
|
Change in Pruritus
Time Frame: Baseline, 12 weeks
|
Pruritus will be measured by the 5-D itch Scale.
The 5-D itch scale was developed as a brief but multidimensional questionnaire designed to be useful as an outcome measure in clinical trials."
The five dimensions are degree, duration, direction, disability and distribution.
The duration, degree and direction domains each include one item, while the disability domain has four items.
All items of the first four domains were measured on a five-point Likert scale (1 = Not present/resolved/never, 5 = Unbearable/getting worse/always).The distribution domain included 16 potential locations of itch, including 15 body part items and one point of contact with clothing or bandages.The scores of each of the five domains are achieved separately and then summed together to obtain a total 5-D score.
5-D scores can potentially range between 5 (no pruritus) and 25 (most severe pruritus)
