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.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    • To assess the central nervous system (CNS), cerebrospinal fluid (CSF) penetration and binding to GCase of ambroxol by the parameters outline (modulation of GCase activity & ambroxol level) at 5 intra-participant dose escalations from day 1 to day 186 at 60 mg TID (day 1-7), 120 mg TID (day 8-14), 180 mg TID (day 15-21), 300 mg TID (day 22-28) and 420 mg TID (day 29-186).

    • To measure the pharmacodynamic effects of ambroxol on GCase activity in blood and CSF following ambroxol oral administration at 5 intra-participant dose escalations from day 1 to 186.
    • To quantify the effect of ambroxol on biomarkers of Parkinson and neurodegeneration at 5 intra-participant dose escalations from day 1 to 186.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. Male or female;

    5. Capable of complying with all study procedures, including fasting lumbar puncture;
    6. Willing to provide a blood sample for screening genomic for Parkinson Disease related DNA analysis and/or consent to Investigators obtaining and using participants previous DNA results if applicable;
    7. Willing and able to self-administer oral ambroxol medication, from day 1 to 186 (at 60 mg TID (day 1-7), 120 mg TID (day 8-14), 180 mg TID (day 15-21), 300 mg TID (day 22-28) and 420 mg TID (day 29-186));
    8. Able to travel to the participating study site;
    9. A female participant is eligible to participate if she is of:
    • Non-childbearing potential defined as pre-menopausal females with a
    documented tubal ligation or hysterectomy; or postmenopausal defined as 12
    consecutive months of spontaneous amenorrhea, at least 6 weeks post-surgical
    bilateral oophorectomy (with or without hysterectomy) or post tubal
    ligation. In questionable cases, menopausal status will be confirmed by
    demonstrating levels of follicle stimulating hormone (FSH) 25.8 – 134.8 IU/L
    and oestradiol < 201 pmol/l at entry.
    • Women of child-bearing potential must use accepted contraceptive methods
    (listed below), and must have a negative serum at screening visit 1 and
    urine pregnancy tests at subsequent visits if applicable. An additional
    pregnancy test will be performed, and results obtained, prior to
    administration of the first dose of ambroxol.

    Accepted contraception methods:
    • True abstinence: When this is in line with the preferred and usual lifestyle of the participant. [Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception).

    Contraceptive Methods with a Failure Rate of < 1%:
    • Oral contraceptive, either combined or progestogen alone;
    • Injectable progestogen;
    • Implants of levonorgestrel;
    • Estrogenic vaginal ring;
    • Percutaneous contraceptive patches; -
    • Intrauterine device (IUD) or intrauterine system (IUS) that meets the <1% failure rate as stated in the product label;
    Please note:
    - All male and female participants of child bearing potential must agree with their partners to use double-barrier birth control or abstinence while participating in the study and for 2 weeks following the last dose of the study drug.
    - Participants may continue to take PD medications including glutamate antagonists, anticholinergics, dopamine agonists, Levodopa (L-DOPA and decarboxylase (DDC) inhibitor), Monoamine oxidase B (MAO-B) inhibitors catechol-O-methyltransferase (COMT) inhibitors, beta blockers, selective serotonin uptake inhibitors (SSRIS), tricyclic antidepressants (TCAs) and indomethacin.
    E.4Principal exclusion criteria
    Participants are excluded from participating in this study if 1 or more of the following criteria are met:
    1. Current treatment with anticoagulants (e.g. warfarin) that might preclude safe completion of the lumbar puncture and in the opinion of the Investigator;
    2. Current use of investigational medicinal product or participation in another interventional clinical trial or who have done so within 30 days prior to the first dose in the current study;
    3. Exposure to more than three investigational medicinal products within 12 months prior to the first dose in the current study;
    4. Confirmed dysphagia that would preclude self-administration of ambroxol up to 7 tablets TID for the duration of day 1 to day 186);
    5. Significant known lower spinal malformations or other spinal abnormalities that would preclude lumbar puncture;
    6. History of known sensitivity to the study medication,ambroxol or its excipients (lactose monohydrate, granulated microcrystalline cellulose, copovidone and magnesium stearate) in the opinion of the investigator that contraindicates their participation;
    7. History of known rare hereditary disorders of galactose intolerance, Lapp lactase deficiency or glucose-galactose malabsorption;
    8. Evidence or history of hypersensitivity to lidocaine or its derivatives;
    9. History of drug abuse or alcoholism in the opinion of the Investigator that would preclude participation in the study;
    10. Donation of blood (one unit or 350 ml) within three months prior to receiving the first dose of the study drug;
    11. Pregnant or breastfeeding;
    12. All participants of child bearing potential in the opinion of the Investigator that would preclude participation in the study and who do not agree to use double-barrier birth control or abstinence while participating in the study and for two weeks following the last dose of study drug;
    13. Any clinically significant or unstable medical or surgical condition that in the opinion of the PI or PI-delegated clinician may put the participant at risk when participating in the study or may influence the results of the study or affect the participant’s ability to take part in the study, as determined by medical history, physical examinations, electrocardiogram (ECG), or laboratory tests. Such conditions may include:
    a) Impaired renal function
    b) Moderate/Severe hepatic impairment
    c) A major cardiovascular event (e.g. myocardial infarction, acute coronary syndrome, decompensated congestive heart failure, pulmonary embolism, coronary revascularisation that occurred within 6 months prior to the screening visit.
