Brief Summary:
This is a prospective, observational, non-interventional patient registry designed to document long term safety and clinical outcomes for 10 years in patients treated with Cholbam/Kolbam, including those who have been using Cholbam/Kolbam and those who start Cholbam/Kolbam treatment at enrollment.

Condition or disease
Bile Acid Synthesis Disorders

Detailed Description:
No experimental intervention is involved; patients in the Registry undergo clinical assessments and receive care as determined by the patient's treating physician.

Study Type : Observational [Patient Registry]
Estimated Enrollment : 110 participants
Observational Model: Cohort
Time Perspective: Prospective
Target Follow-Up Duration: 10 Years
Official Title: A Prospective, Observational, Non-Interventional, Post-Marketing, Patient Registry to Collect Data on Routine Clinical Care in Patients Treated With Cholbam®/Kolbam® (Cholic Acid)
Actual Study Start Date : July 10, 2017
Estimated Primary Completion Date : July 2030
Estimated Study Completion Date : August 2030

Primary Outcome Measures :
  1. Number of Participants with New-Onset or Worsening Cholestasis [ Time Frame: 10 Years ]
    Safety and effectiveness will be measured by new-onset or worsening cholestasis. Worsening cholestasis will be identified by measuring direct total bilirubin concentration, and will be defined as a 25% increase from previous measurement if the total bilirubin is >1mg/dL. New-onset cholestasis will be identified by detecting abnormal direct bilirubin concentration >1mg/dL or direct bilirubin greater than 20% of the total bilirubin if total bilirubin is >5mg/dL.

  2. Number of Participants with Steatorrhea Leading to Poor Growth [ Time Frame: 10 Years ]
    Safety and effectiveness will be measured by steatorrhea leading to poor growth in children, which will be defined as a decrease in percentiles from the original percentile at enrollment to the registry study.

  3. Number of Participants changes in Serum Levels of Fat Soluble Vitamins [ Time Frame: 10 Years ]
    Safety and effectiveness will be measured changes in serum levels of fat soluble vitamins measured by deficiencies identified by comparing results from serum assays (Vitamin A: Retinol, Vitamin D: 250HD2 + 250HD3, Vitamin K: Serum Vitamin K, Vitamin E: Serum Vitamin E) for each vitamin with standard ranges.

  4. Number of Participants with Growth Failure [ Time Frame: 10 Years ]
    Safety and effectiveness will be measured by growth failure will be defined as a decrease in percentiles from the original percentile at entry point into the registry study.

  5. Number of Participants with Treated Related Adverse Events [ Time Frame: 10 years ]
    Number of participants with treatment-related adverse events as assessed by CTCAE v4.0
