Cholestasis Drug: Ursodiol Drug: placebo Phase 2 Phase 3

Study Type: Interventional

Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)

Further study details as provided by Ibrahim Mohamed, St. Justine's Hospital:

Primary Outcome Measures:
  • Length of parenteral nutrition associated cholestasis (in days) [ Time Frame: at the end of cholestasis (when conjugated bilirubin < 34 mmol/L) average of 4 weeks. ]

Secondary Outcome Measures:
  • Peak value of biomarkers associated with cholestasis (Gamma-glutamyl transpeptidase, Alkaline phosphatase, conjugated bilirubin) [ Time Frame: at least once a week, during cholestasis ]
  • 1- Other hepatic marker (Aspartate transaminase, alanine transaminase, albumin blood level) [ Time Frame: at least once a week, during cholestasis ]
  • Length required to minimal enteral feeding (120mL/kg/day) measured in days. [ Time Frame: From birth to outcome (usually less than 21 days) ]
  • Weight gain (in g/kg/day) [ Time Frame: From birth to resolution of cholestasis (very varuiable but usually less than 3 months) ]
  • Adverse effects linked to ursodiol [ Time Frame: From beginning to the end of the medication (average 4 weeks) ]

Enrollment: 26
Study Start Date: October 2008
Study Completion Date: March 2013
Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Ursodiol
Participants assigned in this arm receive an ursodiol suspension at 20mg/ml.
Drug: Ursodiol

Ursodiol is given by mouth, three times a day from second value of elevated conjugated bilirubin (>33mmol/L) to the resolution of cholestasis (conjugated bilirubin <34mmol/L) If Nil per os, 3,3mg/kg/dose is given. If Nil per os is required (e.g. pre-surgery, or necrotizing enterocolitis), none is given.

If enteral feeding is under 100mL/kg/day, 6,7 mg/kg/day is given. If enteral feeding exceeds 100mL/kg/day, 10 mg/kg/day is given.

Other Names:
  • Urso
  • ursodeoxycholic acid
Placebo Comparator: placebo
A placebo suspension that looks like the ursodiol suspension used.
Drug: placebo
Placebo given in the same amount that ursodiol would be given, depending on enteral feeding and weight. It is also given three times a day, until cholestasis resolution.

Detailed Description:

This is the first randomised controlled study that address the question of the role of ursodiol as treatment of cases of PNAC.

It includes all neonates with stratification of less than and equal to 32 weeks or more than 32 weeks of gestation.
