Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

  • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).


    The EU Clinical Trials Register currently displays   43865   clinical trials with a EudraCT protocol, of which   7286   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    General information about the trial
    Main objective of the trial
    To investigate the safety and efficacy of multiple HHLivC infusions in children with ornithine transcarbamylase deficiency (OTCD), carbamoylphosphate synthetase I deficiency (CPS1D), or argininosuccinate synthetase deficiency (ASSD or citrullinemia).
    Protection of trial subjects
    This study was conducted in accordance with "Good Clinical Practice" (GCP) and all applicable regulatory requirements, including the Declaration of Helsinki or with the laws and regulations of the country in which the research was conducted. The protocol, the ICF, and all other required documents were approved by the IRB/IEC prior to the initiation of the study at each institution.

    End point timeframe
    Safety was evaluated from (first atempt of ) the catheter placement, during the HHLivC cell infusion and during the follow-up until either orthotopic liver transplantation, or the end of the study period
    Notes
    [1] - No statistical analyses have been specified for this primary end point. It is expected there is at least one statistical analysis for each primary end point.
    Justification: In view of the exploratory nature of the study and the limited number of patients, all safety analyses were performed with descriptive statistics only.

    Adverse events

    Close Top of page
    Adverse events information
    Timeframe for reporting adverse events
    there are 3 reporting groups, with the same 12 subjects but subdivided over 3 periods -before first catheter placement (attempt) -between catheter placement and (first) OLT (OLT not included) - after (first ) OLT
    Adverse event reporting additional description
    there were 10 subjects, and every single event in every patient was reported, thus the frequency threshold is 10%

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    19 May 2011
    • Added additional time points of blood sampling following administration of 13C Sodium Acetate of 30, 40, and 50 minutes • Added clarifying language to inclusion criteria #2 allowing those subjects without DNA confirmation but who were diagnosed prenatally or via newborn screen to be reviewed for enrollment if the peak ammonia level at first crisis did not reach 500 µmol/L • Added diabetes and cholesterol screen at V2 • Added additional ultrasound at V0 • Added additional immunosuppression trough at V0 • Added clarification of safety parameters needed prior to catheter placement • Added analysis for all routine laboratory screening to search for trends • Generalized text to allow centers to use own standardized procedures (eg, antibiotic prophylaxis, biopsy, infectious disease screening/prophylaxis) • Added clarifying language and literature references concerning 13C assay • Added exploration analysis of SOC samples • Clarified exclusion criteria #6 regarding coagulopathy • Added stipulation that catheter may only be inserted if the total plasma ammonia is ≤ 250 μmol/L
    26 Jun 2012
    • Introduced anti-HLA-assessments prior to and after cell infusion in order to assess a possible immune reaction of the subject against the liver cells • Added time windows for study visits • Reduced visits between V14-V20 from 7 to 3 visits • Defined study termination more precisely • Corrected FU visit schedule • Specified safety reporting period • Added instructions for handling of portal vein catheter dislocation • Adapted time points and volumes in 13C assay
    21 Jun 2013
    • Added exclusion criteria of portal vein thrombosis and veno-occlusive diseases • Increased window on follow-up visits from +/- 5/6 days to +/-14 days • Reduced selected clinical laboratory parameters sampling time points (unless clinically indicated) to reduce the volume of blood required • Reworded language to match pediatric investigational plan language • Updated study contact information • Added interim analysis
    06 Oct 2013
    • Changed study reference/control group: Removed group-match, control group to be replaced with efficacy and safety comparison with current standard of care to be completed in separate project • Increased total number of subjects from 20 to 21 • Added long-term safety data surveillance • Removed secondary efficacy variable of comparison of enzyme active before and after HHLivC infusion • Updated timing and data analysis of interim analysis; removed matched historic controls • Deleted detailed language defining clinical significance of ureagenesis • Added measures and documentation in case of overdose • Updated statistical methods accordingly; including adding time points for 13C urea evaluation, added parameter to monitor protein intake, updated MedDRA version
    26 Mar 2015
    • Added between-visit parental safety check telephone calls to review AEs, concomitant medications, hospitalization, and other important subject information • Added time points for analysis of anti-HLA antibody formation • Included post-OLT questionnaire to capture complications of OLT due to previous liver cell therapy • Modified safety reporting information for harmonization with other CCD05 study documents • Clarified management of premature discontinuation of treatment/ early study discontinuation, especially subjects who did not receive all infusions • Removed promotional language from benefits summary • Added risks of study measures and LCT previously only described in IB • Expanded study to regions outside the US • Clarified listed cell dosage was targeted cell dosage, allowing deviations up to 15% • Added section describing traceability of cell preparation and administration • Updated study background with current trial data and recent literature • Expanded window between consent and first study visit to 28 days
