Criteria

Inclusion Criteria:

• Primary biliary cirrhosis will be defined as present when 2 of 3 of the following criteria are met:

• Chronic cholestatic liver disease for greater than 6 months with alkaline phosphatase levels greater than 1.5 times the upper limit of normal prior to UDCA treatment.

• Positive AMA titer greater or equal to 1:40 or AMA greater than 0.1U. Liver histology in the past with features consistent with or diagnostic of PBC.

• A previous ultrasound, computed tomography (CT), or cholangiography of the biliary tree excludes biliary obstruction.

• Verbal report of fatigue for greater than 6 months.

Exclusion Criteria:

• Patients with other serious coexistent conditions such as pre-existing advanced malignancy or severe cardiopulmonary disease which would be expected to limit their expectancy to less than three years.

• Findings highly suggestive of liver disease of other etiology such as chronic alcoholic liver disease, chronic hepatitis B or C infection, hemochromatosis, Wilson's disease, 1-antitrypsin deficiency, non-alcoholic steatohepatitis or sclerosing cholangitis.

• Treatment of underlying PBC has been modified in the preceding six months.

• Anticipated need for transplantation in one year (Mayo survival model <80% one-year survival without transplant) or MELD above 15.

• Recurrent variceal bleeding, presence of diuretic-resistant ascites, or spontaneous encephalopathy.

• Active drug or alcohol use.

• History of drug and/or stimulant (e.g. methylphenidate, amphetamine, or cocaine) abuse.

• Serum bilirubin >4 mg/dl.

• Serum creatinine over 1.4 mg/dl.

• Pregnancy.

• Breast-feeding.

• Inability or unwillingness to practice contraceptive measures for the prevention of pregnancy if appropriate.

• Other fatigue related diagnoses such as anemia, thyroid disease, renal failure, use of beta-blockers and untreated depression.

• Known hypersensitivity to modafinil.

• Uncontrolled hypertension.

• Patients with hypertension and left ventricular hypertrophy documented on ECG in the last 2 years.

• Recent (<6 months) history of myocardial infarction or unstable angina.

• Patients with history of psychosis.

• Patients receiving cyclosporine, warfarin, tricyclic agents, carbamazepine, phenobarbital, rifampin, ketoconazole or itraconazole in the last 3 months.
