Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 5 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Prospective, Open Label, Multicenter, Efficacy and Safety Study of Several Infusions of HepaStem in Urea Cycle Disorders Paediatric Patients
Actual Study Start Date : October 2014
Actual Primary Completion Date : March 2017
Actual Study Completion Date : March 2017

Arm Intervention/treatment
Experimental: HepaStem
Target total dose 50x10E6 cells/kg
Biological: HepaStem
HepaStem will be administered in maximum 4 infusion days, spread over an 8-week period with an interval of 2 to 3 weeks between infusion days. The target total dose of cells will be 50x10E6 cells/kg body weight

Primary Outcome Measures :
  1. Efficacy as determined by de novo ureagenesis (C13 tracer method) [ Time Frame: at 6m post-first infusion day ]

Secondary Outcome Measures :
  1. Efficacy as determined by de novo ureagenesis (C13 tracer method) [ Time Frame: at 3, 9 and 12 months post-first infusion day ]
  2. Efficacy as determined by Ammonia (NH3) values [ Time Frame: up to 12 months post-first infusion day ]
  3. Efficacy as determined by amino acids in plasma [ Time Frame: up to 12 months post-first infusion day ]
  4. Efficacy as determined by report of metabolic decompensations [ Time Frame: up to 12 months post-first infusion day ]
  5. Efficacy as determined by report on actual supportive treatment, adjustment of protein restriction and amino acids supplements [ Time Frame: up to 12 months post-first infusion day ]
  6. Efficacy as determined report on behavior, cognitive skills and health-related quality-of-life indicators [ Time Frame: up to 12 months post-first infusion day ]
  7. To evaluate the safety during the year following HepaStem infusions (composite) [ Time Frame: up to 12 months post-first infusion day ]
    Safety evaluation in terms of (1) clinical status, (2) portal vein hemodynamics, (3) morphology of the liver, bile ducts and portal system, (4) laboratory tests, (5) De novo detection of donor-specific circulating anti-human leukocyte antigen (HLA) antibodies, and/or other immune-related markers, (6) serious adverse events and clinically significant adverse events related to HepaStem, technical intervention, and concomitant treatments.

Ages Eligible for Study:   up to 12 Years   (Child)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Main Inclusion Criteria:

  • Paediatric patients < 12 years prior to infusion
  • Patient presents with UCD
  • Patient shows patency of the portal vein and branches, with normal flow velocity as confirmed by Doppler US and accessibility of the portal vein and /or affluants.

Main Exclusion Criteria:

  • Patient has mild disease severity, easily controlled under standard of care therapy, with no recurrent metabolic crises.
  • Patient is registered on a liver transplant waiting list or is scheduled for living donor liver transplantation before the end of the study.
  • Patient presents acute liver failure.
  • Patient presents clinical or radiological evidence of liver cirrhosis.
  • Patient presents or has a history of hepatic or extrahepatic malignancy.
  • Patient has a known clinically significant cardiac malformation.
  • Patient has a personal history of venous thrombosis, or has a clinically significant abnormal value for protein S, protein C, anti-thrombin III, and /or activated Protein C Resistance (aPCR) at screening. In case of known family history, a complete coagulation work-up should be performed. In all above described cases, results need to be discussed with PB before enrolling the patient in the study.
  • Patient had or has a renal insufficiency treated by dialysis.
