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   43871   clinical trials with a EudraCT protocol, of which   7290   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.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    To assess the long-term safety of HepaStem therapy post administration in patients who have been infused with at least one dose of HepaStem in a previous interventional clinical study conducted by Promethera Therapeutics.
    E.2.2Secondary objectives of the trial
    not applicable
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. Patients who have received at least one infusion of HepaStem during a previous interventional clinical study conducted by Promethera Therapeutics
    Note: Patients currently participating in ongoing double-blinded controlled interventional studies during which HepaStem is administered will be invited to enter the PROLONGSTEM study. Once this double-blinded controlled interventional study is complete and/or treatment is unblinded, the patients will be informed about the treatment they received. HepaStem-recipients will remain in the PROLONGSTEM study, and the participation of control-recipients in the PROLONGSTEM study will be terminated.
    2. Patients who are able to understand and give written informed consent
    For children (as defined according to national regulations), an informed consent shall be sought from the parents or legal representative on behalf of the child. If the child is capable of understanding the purpose of the study, he/she should provide an informed assent and sign an assent form. Minor patients at the time of inclusion who become adult (according to national regulations) during the course of the PROLONGSTEM study should provide an informed consent (and sign the adul ICF) as soon as they reach adulthood.
    For adult patients who are legally incapable of providing informed consent at the time of inclusion (due to an incapacitating condition such as brain disease or hepatic encephalopathy), a legal representative should provide a signed informed consent before enrollment. After improvement of the incapacitating condition, and as soon as the investigator considers that the patients have become capable to consent by themselves, the patients must sign the ICF.
    E.4Principal exclusion criteria
    1. Patients who received an orthotopic liver transplantation and who completed the 6-month follow-up Organ Transplantation Questionnaire prior to the start of the PROLONGSTEM study.
    Note: Patients who received an orthotopic liver transplantation and who did not complete the 6-month follow-up Organ Transplantation Questionnaire prior to the start of the PROLONGSTEM study may be included in the PROLONGSTEM study. These patients will remain in the PROLONGSTEM study until the completion of the 6-month follow-up Organ Transplantation Questionnaire. Data from the last visit of the previous clinical study conducted by the Sponsor (i.e., the start of the PROLONGSTEM study) up to the date of completion of the 6-month follow-up Organ Transplantation Questionnaire will be collected.
    2. Patients who received mature liver cells or stem cells other than HepaStem prior to the start of the PROLONGSTEM study.
    Note: Patients who received mature liver cells or stem cells other than HepaStem after the last visit of the previous clinical study conducted by the Sponsor (i.e., the start of the PROLONGSTEM study) may be included in the PROLONGSTEM study. Only retrospective data (between the last visit of the previous study and before the administration of such cells) will be collected from those patients.
    E.5 End points
    E.5.1Primary end point(s)
    To document the occurrence of adverse events of special interest (AESIs) as defined below:
    • Event with fatal outcome (death)
    • Organ transplantation and outcome
    • Development of malignancy or unwanted tissue formation in different organs (tumor development malignant or not)
    • Disease linked to transmission of adventitious agents or reactivation of latent pathogens
    • Any adverse event (AE) judged to have a plausible causal relationship to HepaStem
    These AESIs should be reported according to the reporting rules set for serious adverse events (SAEs).
    E.5.1.1Timepoint(s) of evaluation of this end point
    The planned follow-up of each patient in the PROLONGSTEM study is up to 60 months (5 years) after the patient’s last visit in the previous clinical study conducted by the Sponsor.
