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
    The primary objectives of the study are: • To evaluate the safety profile of rhLAMAN (Lamazym) • To determine the PK profile of rhLAMAN (Lamazym) in patients with alpha-mannosidosis as measured by rhLAMAN levels in plasma
    Protection of trial subjects
    The study was conducted in accordance with the declaration of Helsinki, good clinical practice (GCP) guidelines and local law requirements. Other than routine care, no specific measures for protection of trial subjects were implemented. Although an Independent Data Monitoring Committee was not formally established , a Safety Committee (SC) did exist for this study.

    Lamazym 6.25 U/kg - Group 1
    Arm description
    A fixed dose regimen was chosen (6.25, 12.5, 25, 50 or 100 U/kg). The dose was determined after an evaluation at baseline and on the basis of which group the patient was stratified to (from 1-5). Each patient was to receive an infusion once a week. The number of infusions was dependant on the group number the patient was stratified to hence the onset of the first infusion for each patient. Infusions were administered weekly commencing with group 1, where patients received their first dose at Day 0 (Visit 3). One week later (7 days ± 2 days) group 2 received their first infusion (Visit 3) whereas group 1 received their second dose (Visit 4) and so on until group 5 who would have only one infusion before entering phase IIa. Group 1 was expected to receive a total of 5 doses, group 2, 4 doses and so on until group 5, which was expected to receive only 1 dose.

    Reporting group title
    Lamazym 6.25 U/kg - Group 1
    Reporting group description
    A fixed dose regimen was chosen (6.25, 12.5, 25, 50 or 100 U/kg). The dose was determined after an evaluation at baseline and on the basis of which group the patient was stratified to (from 1-5). Each patient was to receive an infusion once a week. The number of infusions was dependant on the group number the patient was stratified to hence the onset of the first infusion for each patient. Infusions were administered weekly commencing with group 1, where patients received their first dose at Day 0 (Visit 3). One week later (7 days ± 2 days) group 2 received their first infusion (Visit 3) whereas group 1 received their second dose (Visit 4) and so on until group 5 who would have only one fusion before entering phase IIa. Group 1 was expected to receive a total of 5 doses, group 2, 4 doses and so on until group 5, which was expected to receive only 1 dose.
