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   44334   clinical trials with a EudraCT protocol, of which   7366   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.3Principal inclusion criteria
    1. Healthy male and female subjects, 18 to 45 years of age, inclusive. Healthy status is defined by absence of evidence of any active or chronic disease following a detailed medical and surgical history, a complete physical examination including vital signs, 12-lead ECG, hematology, blood chemistry, blood serology and urinalysis. In the case of uncertain or questionable results, tests performed during screening may be repeated before randomization to confirm eligibility or judged to be clinically irrelevant for healthy subjects;
    2. Body mass index (BMI) between 18 and 30 kg/m2 and a minimum weight of 50 kg, inclusive;
    3. Fitzpatrick skin type I-III (Caucasian);
    4. Female subjects of childbearing potential must use effective contraception for the duration of the study;
    5. Able and willing to give written informed consent and to comply with the study restrictions.
    E.4Principal exclusion criteria
    Eligible subjects must meet none of the following exclusion criteria at screening:
    1. History of pathological scar formation (keloid, hypertrophic scar) or keloids or surgical scars in the target treatment area that in the opinion of the investigator, would limit or interfere with dosing and/or measurement in the trial;
    2. Diagnosed with psoriasis or family history of psoriasis
    3. History of skin cancer (basal cell carcinoma, squamous cell carcinoma, melanoma);
    4. Have any current and / or recurrent clinically significant skin condition at the treatment area (e.g. atopic dermatitis); including tattoos;
    5. Using immunosuppressive or immunomodulatory medication within 30 days prior to enrolment or planned to use during the course of the study;
    6. Use of topical medication (prescription or over-the-counter [OTC]) within 30 days of study drug administration, or less than 5 half-lives (whichever is longer) in local treatment area;
    7. Participation in an investigational drug or device study within 3 months prior to screening or more than 4 times a year;
    8. Loss or donation of blood over 500 mL within three months prior to screening or donation of plasma within 14 days of screening;
    9. Any (medical) condition that would, in the opinion of the investigator, potentially compromise the safety or compliance of the patient or may preclude the patient’s successful completion of the clinical trial;
    10. Any vaccination within 30 days prior to initial IMQ dosing or planned during the course of the study with exception of vaccination for SARS-CoV-2;
    11. Vaccination for SARS-CoV-2 within 14 days prior to initial IMQ dosing, or planned during the course of the study;
    12. Chronic infection with HIV, hepatitis B (HBV) or hepatitis C (HCV). A positive HBV surface antigen (HBsAg) test at screening excludes a subject;
    13. A history of ongoing, chronic or recurrent infectious disease;

    17. Volunteers with clinically relevant infections
    18. Hypersensitivity for dermatological marker at screening
