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.

    2. Female or male subjects aged 18 years or older.
    3. For women of childbearing potential: negative pregnancy tests at Screening Visit (Visit 1), the Randomization Visit (Visit 2), and prior to each reapplication of the IMP, and must have agreed to practice medically acceptable methods of birth control.

    Confirmation of diagnosis of chronic moderate to severe PSNP (see also Protocol Table 1)
    4. Documented diagnosis of PSNP by the following criteria:
    a. A history of post-surgical pain with a duration of at least 6 months to maximally 36 months that is plausibly related to the surgical intervention as documented on a body map.
    b. DN4i of at least 3 out of 7 points at Visit 1.
    c. The pain must extend beyond the scar area to neuroanatomically adjacent skin areas and be related to the site of the surgery.
    5. Documented diagnosis of probable or definite PSNP according to the following criteria:
    a. The pain must be associated with sensory signs in the same neuroanatomically plausible distribution. The area of sensory changes may extend beyond, be within, or overlap with the area of pain (criterion for probable neuropathic pain), or
    b. In addition to 5a : Direct surgical evidence (e.g., surgeon´s clear verification of an intraoperative nerve lesion) (criterion for definite neuropathic pain).
    6. The subject has moderate to severe pain with a baseline value for 24-hr average pain intensity of at least 4 points on the NPRS. The baseline value is calculated as the average of the 24-hr average pain intensity ratings of the Baseline Phase (Day -7 to Day -1). At least 5 (out of 7) pain ratings should be available during the Baseline Phase. If less than 5 pain ratings are available, the subject may be rescheduled for Visit 2 (1 time only) after having received appropriate re-training in the use of the e-diary to ensure compliance.

    Suitability for treatment with IMP
    7. The size of the affected painful intact skin area is not larger than the size of 4 standard Qutenza topical systems (1120 cm2).
    8. The skin in the area where the IMP will be applied, and that may also contain the scar tissue, is intact, dry, and non-irritated (i.e., there are no signs and symptoms of skin disease, skin irritation, inflammation or injury, such as active herpes zoster lesions, atopic dermatitis, ulceration, wounds).
    Eligibility with regard to protocol adherence, to allowed pre-treatments and concomitant treatments
    9. The subject is willing to adhere to the restricted use of concomitant treatments (see concomitant treatments in Section 1.4.2).
    10. The subject experiencing pain is:
