E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the therapeutic efficacy of commercial cholic acid capsules, hard. |
|
E.2.2 | Secondary objectives of the trial |
To assess the safety and tolerability of cholic acid |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Patients completing protocol CAC-001-01 or transitioned from protocol 91-10-10 or children with newly diagnosed inborn errors of bile acid synthesis.
Any new, additional infants, children, and adolescents presenting for evaluation of cholestasis defined as a conjugated bilirubin > 2mg/dl or evaluation chronic liver disease, fat and fat soluble vitamin deficiency, growth failure or other signs or symptoms consistent with intestinal intraluminal bile acid deficiency. Patients will have undergone thorough evaluation to define the etiology of cholestasis using conventional screening studies (urine culture α-1-antitrypsin pheno¬type, endocrine studies, STORCH titers, thyroid function tests, liver ultrasound, liver "function" tests and percutaneous liver biopsy).
Older patients of any age with chronic liver disease if urine screens indicate that they have inborn errors of bile acid metabolism.

E.5 End points |
E.5.1 | Primary end point(s) |
Therapeutic effect of commercial cholic acid capsules on:
- serum transaminases and
-suppresson of bile acid synthesis of atypical bile acids, as measured in urine and serum bile acid analysis using mass spectrometry.
- |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Liver biochemistries (serum total/direct bilirubin, ALT, AST, total protein, albumin, alkaline phosphatase, GGT and prothrombin time with INR (optional) as a part of standard of care by the attending physician and serum and urine for bile acid analysis by GC-MS, LC-MS and LSIMS will be performed every one month for the first three months, and then every 3-6 months based upon clinical condition of the patient for the next-12 months after starting therapy.
Thereafter, adjustments in cholic acid dose will be made based upon urinary FAB analysis and frequency of repeat urine FAB-MS analysis will be performed as needed at least annually.
Liver biochemistries and urine LSIMS will be performed at least annually as part of standard of care for patients with chronic liver disease.
|
|
E.5.2 | Secondary end point(s) |
Safety and tolerability of TBM cholic acid capsules, as assessed by vital signs, physical examination findings, clinical laboratory results and the incidence and severity of adverse events, compared with baseline data.
Assessment of malabsorption: height/weight gain, normalisation of steatorrhoea, measurements of vitamin A,E and D and prothrombin time. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Every one month for the first 3 months and then 3-6 months based on the clinical condition of the patient for the next 12 months after starting therapy. Thereafter perfomed at least annually. |
