10-15 mg/kg body weight/day taken orally.
A Phase III, open label, single arm, nonrandomized, non-comparative, compassionate treatment study of cholic acid in the treatment of defects of bile acid metabolism.
The study was begun with a single study site at Cincinnati Children's Hospital Medical Center (CCHMC), but in 2005 was expanded so that compassionate treatment could be provided to additional patients who had been identified with inborn errors of bile metabolism through the center's screening/diagnostic program.
Patients who were screened were contacted and evaluated with respect to the inclusion/exclusion criteria. Signed informed consent by the patient and/or parents/legal guardian was obtained as soon as it is confirmed that the patient met inclusion/exclusion criteria and the parents/guardian would agree for the child to participate in the study.
The primary interventions for the study were:
- Administration of study drug.
- Collection of baseline physical exam, vital signs, blood and urine samples for laboratory tests.
- Collection of periodic physical exam, vital signs, blood and urine samples for laboratory tests during the period of administration of the study drug.
- Collection of any adverse event information.
Time and Events Schedule:
- Confirm eligibility
- Obtain written informed consent from patient and/or parents/legal guardian
Collect demographic data and disease and medication history, including family history
Baseline and Ongoing:
- Obtain body weight
- Record adverse events
- Obtain blood and urine samples for laboratory tests
- Initiate study drug therapy & monitor study drug therapy and adjust dose as needed
