Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.

    The EU Clinical Trials Register currently displays   37527   clinical trials with a EudraCT protocol, of which   6154   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).
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.3Principal inclusion criteria
    1. Subject will sign and date an informed consent form (ICF)

    2. Willing and able to comply with scheduled visits, treatment plan, study restrictions, laboratory tests, contraceptive guidelines, and other study procedures

    3. Subjects (male and female) will be between the ages of 18 and 80 years, inclusive.

    4. Body mass index (BMI) of ≥18.0 kg/m2

    5. Diagnosis of small fiber neuropathy, as per European Federation Neurological Societies (EFNS)/American Academy of Neurology (AAN) guidelines, with pain for at least 3 months prior to screening

    6. Reduction below the 5th percentile of sex and age-adjusted normal values in epidermal nerve fiber density on punch skin biopsy at the distal site of the leg performed at or within 6 months of screening

    7. Presence of sural nerve responses

    8. Average NRS score between ≥4 and ≤9 reported in the daily diary on Days -7 through -1
    E.4Principal exclusion criteria
    1. History in the past 10 years of malignancy except for squamous cell skin cancer, basal cell skin cancer, and Stage 0 cervical carcinoma in situ (all 3 with no recurrence for the last 5 years)

    2. Exposure to neurotoxic drugs (i.e., chemotherapy) since diagnosis of small fiber neuropathy. Untreated or uncontrolled connective tissue disorders, sarcoidosis, Sjögren’s syndrome, amyloidosis, Fabry’s disease, celiac disease, Lyme disease, autoimmune disorders (i.e., as assessed by anti-nuclear antibodies, rheumatoid factor, sedimentation rate, and/or lupus anticoagulant)
    including myasthenia gravis and Guillain-Barre syndrome, which in the opinion of the investigator makes the subject unsuitable for inclusion in this study.

    3. A known or clinically suspected infection with human immunodeficiency virus or hepatitis B or C viruses

    4. Current clinically significant liver or kidney dysfunction

    5. Current uncontrolled thyroid dysfunction

    6. Subjects with a diagnosis of diabetes who have any 1 of the following criteria:
     - HbA1c ≥11% at screening
    - are not stabilized on oral hypoglycemics and/or subcutaneous insulin or diet, in the opinion of the investigator
     - evidence of ulcers or severe nephropathy resulting from their diabetes
     - advanced retinopathy, defined as greater than State 3 (moderate non-proliferative diabetic retinopathy)
     - history of a clinical atherosclerotic event, such as myocardial infarction or stroke

    7. History of cardiac dysrhythmias requiring anti-arrhythmia treatment(s); or history or evidence of abnormal ECGs that in the opinion of the investigator or medical monitor would preclude the subject's participation in the study

    8. Standard 12-lead ECG demonstrating QTc >450 msec at screening. If QTc exceeds 450 msec, the ECG will be repeated 2 more times, and the average of the 3 QTc values will be used to determine the subject’s eligibility.

    9. Concomitant severe pain conditions (i.e., low back pain, radiculopathy, severe bone and musculoskeletal disorders) which may impair self-assessment of pain due to small fiber neuropathy

    10. Abnormal laboratory results indicative of any significant medical disease that, in the opinion of the investigator, would preclude the subject's participation in the study

    11. Other serious, acute, or chronic medical or psychiatric illness that, in the judgment of the investigator, could compromise subject safety, limit the subject’s ability to complete the study and/or compromise the objectives of the study

    12. Female subjects who are pregnant, nursing, or planning to become pregnant during the study or within 90 days after the last study drug dose

    13. Male subjects with a female partner who is pregnant, nursing, or planning to become pregnant during the study or within 90 days after the last study drug dose

    14. Use of restricted medication or food within the specified duration before the first dose of study drug

    • A positive drug screen for a known concomitant medication that is not otherwise exclusionary (e.g., benzodiazepines) will not disqualify subjects; however, marijuana and marijuana derivatives will not be allowed

    16. Subject, or close relative of the subject, is the investigator or a subinvestigator, research assistant, pharmacist, study coordinator, or other staff directly involved with the conduct of the study at that site
