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   43857   clinical trials with a EudraCT protocol, of which   7284   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.

    5. Subjects considered by the investigator to be at serious risk for suicide or aggressive behavior
    6. Mental condition, including mental retardation, rendering the individual unable to understand the nature, scope, and possible consequences of the study and/or constituting evidence of an uncooperative attitude
    7. Other DSM-IV Axis-I or Axis III (medical) diagnoses that the investigator judges to be the primary source of anxiety for the subject
    8. A history of a seizure disorder, except febrile seizures of childhood
    9. Current diagnosis of neuropathic pain
    10. Any serious or uncontrolled medical illness, in the opinion of the investigator, which will render the subject unsuitable for the study
    11. A urine toxicology screen at screening and/or baseline visit/s positive for any of the following substances or classes of compounds: alcohol, benzodiazepines, amphetamines, barbiturates, opiates, methadone, cocaine, phencyclidine (PCP), cannabinoids
    12. Known sensitivity to pregabalin, other drugs structurally related to the neurotransmitter GABA, alprazolam, or other benzodiazepines
    13. Presence or history of narrow angle glaucoma
    14. History of non-response to alprazolam, other benzodiazepines, gabapentin or pregabalin given for the treatment of anxiety

Antidepressant, anxiolytic, antipsychotic, sedative (other than zopiclone or zolpidem for insomnia), hypnotic or psychoactive drug use (including pregabalin and gabapentin) within 2 weeks (5 weeks for fluoxetine) prior to baseline visit. If medication is required for the treatment of insomnia in the week prior to baseline visit, zopiclone (3.75 mg per night) or zolpidem (5 mg per night) may be taken intermittently (prn) on two or fewer nights until 3 days before baseline visit
    16. Sedating antihistamine use within 24 hours prior to the Baseline visit.
    17. Daily and/or regular use (longer than two months) of benzodiazepines at any dose within the past two years and/or subjects who may have developed a tolerance to alprazolam.
    18. Depot neuroleptics administered within the previous 6 months of baseline visit
    19. All herbal psychoactive treatments within 14 days of baseline visit
    20. Electroconvulsive therapy (ECT) within six (6) months prior to study entry
    21. Subjects who began non-medication interventional therapy for anxiety within 2 months of the study: biofeedback, hypnosis, cognitive behavior therapy eg.
    22. Participation in any other studies involving investigational or marketed products, concomitantly or within 3 months prior to entry in the study
    23. In the judgment of the investigator the subject is unable or unlikely to follow the protocol, or otherwise might not be suitable for the study
    24. Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with trial participation or investigational product administration or may interfere with the interpretation of trial results and, in the judgment of the investigator, would make the subject inappropriate for entry into this trial
    E.5 End points
    E.5.1Primary end point(s)
    A Visual Analogue Scale (VAS) (Appendix 17.2 of the protocol) will be administered to capture onset of action measuring reduction in anxiety symptoms at Screening, Baseline, and at 2, 2.5, 3, 3.5, and 4 hours post-dose.
