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   41225   clinical trials with a EudraCT protocol, of which   6755   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 in adults and that are not part of an agreed PIP are not public in the EU CTR (refer to European Guidance 2008/C 168/02   Art. 3 par. 2 and   Commission Guideline 2012/C 302/03,   Art. 5) .
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The Primary Efficacy Objective of this trial is to evaluate the efficacy of the preladenant doses 2 mg twice daily and 5 mg twice daily compared with placebo in
    subjects with moderate to severe PD experiencing motor fluctuations and receiving a stable dose of L-dopa, as measured by “off” time.
    E.2.2Secondary objectives of the trial
    The Key Secondary Efficacy Objectives for this trial are to evaluate the efficacy of the preladenant doses 2 mg twice daily and 5 mg twice daily compared with placebo in subjects with moderate to severe PD experiencing motor fluctuations and receiving a stable dose of L-dopa, as measured by the proportion of Responders and by “on” time without troublesome dyskinesia.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. Each subject must have a diagnosis of idiopathic PD based on the United Kingdom Parkinson’s Disease Society Brain Bank Criteria (see Appendix 1) and the inclusion/exclusion criteria for this protocol. Each subject should have bradykinesia and at least one of the following
    i. Muscular rigidity
    ii. Resting tremor (4 to 6 Hz; Please note that for the purposes of this
    study, a diagnosis based solely on bradykinesia and postural
    instability is insufficient for diagnosis of idiopathic Parkinson's
    Disease, and subjects diagnosed in this manner cannot be enrolled
    in the study).

    2. Each subject must have received prior therapy with L-dopa for approximately 1 or more years immediately before Screening and must continue to have a beneficial clinical response to L-dopa at Screening.

    3. Each subject must have been on a stable, optimal dopaminergic treatment regimen, defined as maximum therapeutic effect achieved with available anti-parkinsonian treatment, for at least the 5 weeks immediately before Randomization.

    4. Subjects receiving the adjunct PD medications listed in Table 1 [Amantadine, Anticholinergics, Dopa decarboxylase inhibitors, Dopamine agonists, Entacapone, L-dopa] are permitted to enroll in this trial. Each subject who is receiving one or more of the adjunct PD medications listed in Table 1 must have been on a stable regimen of treatment for at least the 5 weeks immediately before Randomization.

    5. Each subject’s Hoehn and Yahr stage must be >=2.5 and ≤4 in the optimum “on” state at Screening

    6. Each subject must be experiencing motor fluctuations with or without dyskinesia following optimum titration of treatment medications and within the 5 weeks immediately before Screening.

    7. Each subject must be experiencing a minimum of 2 hours/day of “off” time as estimated by the investigator and supported by the 3-day symptom diary (Daily Diary) at Randomization.

    8. Each subject, with or without the help of a caregiver, must be capable of maintaining an accurate and complete symptom diary (Daily Diary) as assessed at the Diary Training Visit.
    E.4Principal exclusion criteria
    1. A subject must not have a form of drug-induced or atypical parkinsonism, cognitive impairment (ie, MoCA score <22), bipolar disorder, schizophrenia, or other psychotic disorder.

    2. A subject must not have a history of any of the following:
    • repeated strokes; • with stepwise progression of Parkinsonian features; • repeated head injury; • definitive encephalitis; • oculogyric crises; • neuroleptic treatment at onset of symptoms; • more than one first degree relative affected; • sustained remission; • strictly unilateral features after 3 years; • supranuclear gaze palsy; • cerebellar signs; • early severe autonomic involvement; • severe symptomatic autonomic involvement unrelated to medications; • early severe dementia with disturbances of memory, language, and; praxis; • Babinski sign with clear, clinically significant pyramidal tract involvement; • presence of cerebral tumor or communicating hydrocephalus on; neuroimaging (by history); • negative response to large doses of L-dopa (if malabsorption excluded); • MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine) or known neurotoxin; exposure; • hallucinations unrelated to medications; • stroke within 6 months of Screening or persistent neurological deficit that may; interfere with study assessments; • surgery for PD

    3. A subject must not have an untreated major depressive disorder meeting Diagnostic and Statistical Manual of Mental Disorders IV Text Revision (DSM-IV-TR) criteria or Beck Depression Inventory II] {BDI II} score ≥19. A subject who is successfully treated [Beck Depression Inventory-II] {BDI-II} score < 19) with stable doses of allowed antidepressant medications for at least the 45 weeks immediately before Screening is eligible to enroll in the trial.

    4. A subject must not be at imminent risk of self-harm or harm to others, in the investigator’s opinion based on clinical interview and responses provided on the Columbia Suicide Severity Rating Scale (CSSRS). Subjects must be excluded if they report suicidal ideation of Type 4 or 5 in the past 2 months or suicidal behavior in the past 6 months as measured by the CSSRS during Screening or Randomization Visits.

    5. In the judgment of the investigator, a subject must not have sleep attacks or compulsive behavior that would interfere with the integrity of the trial or would pose a risk to the subject in participating in the trial.
