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   42882   clinical trials with a EudraCT protocol, of which   7063   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) .

    Clinical Trials marked as "Trial now transitioned" were transitioned to the Clinical Trial Regulation 536/2014 and can be further followed in the Clinical Trial Information System  
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    To study the efficay of gabapentin versus placebo in the disorder of impulse control in the Parkinson´s disease, using for its evaluation the Questionnaire for Impulsive-Compulsive Disorder in Parkinson´s Disease.
    Estudiar la eficacia de la gabapentina versus placebo en el Trastorno de control de impulso (TCI) de la enfermedad de Parkinson (EP), mediante la evaluación de su gravedad usando el cuestionario Score in the Questionnaire for Impulsive-Compulsive Disorders in Parkinson's Disease - Rating Scale (QUIP-RS).
    E.2.2Secondary objectives of the trial
    1.To verify if the treatment with gabapentin leads to changes in the Parkinson´s motor state.
    2.To evaluate if gabapentin modifies the anxiety and depression associated to the disorder of impulse control in the Parkinson´s disease.
    3.To analyze if gabapentin has any other effect on the motor aspects related to the Parkinson´s Disease.
    4.To study if the treatment with gabapentin associates to apathy.
    5.To determine the effect of gabapentin versus placebo in the patient´s quality of life.
    6.To verify the security and tolerability of gabapentin, evaluated by the presence of secondary effects.

    1. Comprobar si el tratamiento con gabapentina induce cambios en el estado motor parkinsoniano.
    2. Estudiar si la gabapentina modifica la ansiedad y depresión, que frecuentemente se asocian con el TCI en la EP.
    3. Analizar si la administración de gabapentina tiene efecto sobre otros aspectos no motores relacionados con la EP.
    4. Estudiar si el tratamiento con gabapentina se asocia con apatía (como rasgo de conducta opuesto a la impulsividad)
    5. Determinar el efecto de gabapentina versus placebo en la calidad de vida de los pacientes con TCI.
    6. Comprobar el grado de seguridad y tolerabilidad de la gabapentina, evaluada por la presencia de efectos secundarios, en esta población de pacientes.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1.Subjects with Parkinson´s disease treated with dopaminergic drugs.
    2.Subjects that present disorder of impulse control according to the validated diagnostic criteria (parkinson´s Disease Impulsive-compulsive Disorders diagnostic interview; Weintraub et al, Mov Disror 2009;30:1461-7) who after the gradual reduction of the dopaminergic treatment continue presenting disrorder of the impulse control.
    3.Older than 18 years old.
    4.Signed informed content.
    5.Women of childbearing age should get a negative pregnancy test in serum or urine at the screening visit, and accept the use of adequate contraception for at least 14 days before the first dose of study drug to the 14 days after the last.
