NCT02655315

Brief Summary

This study evaluates the effect of iron chelation as a therapeutic strategy to slow the progression of Parkinson's disease. Half of participants will receive the deferiprone to 15 mg / kg twice daily morning and evening (30mg / kg per day), while the other half will receive a placebo. The treatment lasts nine months.

Outcome Measures

Primary Outcomes (1)

  • Global effect (symptomatic and disease modifying effects) on motor and non motor handicap

    the change in the total Movement Disorders Society-Unified Parkinson Disease Rating Scale score between baseline and 36 weeks (i.e. the end of the placebo-controlled phase for analysis of both disease-modifying and symptomatic effects)

    at 36 weeks

Secondary Outcomes (12)

  • Disease-modifying effect on motor and non motor handicap

    baseline, at 40 weeks

  • Effect of the motor symptoms

    baseline, at 12, 36 and 40 weeks

  • Quality of life and autonomy by PDQ-39 score

    baseline, at 36 and 40 weeks

  • Quality of life and autonomy by Clinical Global Impression score

    baseline, at 36 and 40 weeks

  • Health economics assessment

    baseline, at 36 and 40 weeks

  • +7 more secondary outcomes

Eligibility Criteria

AgeUp to 80 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Adult patients
  • Parkinson's disease diagnosed according United Kingdom Parkinson's disease Society Brain Bank Clinical Diagnostic Criteria and based on the presence of at least two of the three cardinal features of the disease (rest tremor, bradykinesia and rigidity). If rest tremor is not present, subjects must have unilateral onset of symptoms.
  • Treatment-naïve, i.e. the best population for assessing a disease-modifying effect without the interaction of dopaminergic treatment (no dopaminergic agonists, L-dopa, anticholinergics, monoamine oxidase B inhibitors (e.g. rasagiline) or deep brain stimulation).
  • Patients covered by a Health Insurance System in countries where required by law
  • Written informed consent dated and signed prior to the beginning of any procedures related to the clinical trial

You may not qualify if:

  • Disease duration greater than 18 months.
  • Patients with high frequency of comorbidity or vital risks that may reasonably impair life expectancy
  • Hoehn and Yahr stage 3 or more.
  • Significant cognitive impairment (a Mini Mental State Examination score \<24 or an equivalent impairment on a similar scale) or dementia diagnosed in accordance with the Movement Disorders Society criteria (Emre et al., 2007).
  • Atypical or secondary parkinsonism (supranuclear palsy, multisystem atrophy, etc.) or anomalies on MRI suggestive of vascular involvement or significant cortical or subcortical atrophy (i.e. atypical for Parkinson's Disease).
  • Progressing axis I psychiatric disorders (psychosis, hallucinations, substance addiction, bipolar disorder, or severe depression), in accordance with the Diagnostic and Statistical Manual of Mental Disorders.
  • Subjects undergoing brain stimulation.
  • Positive Human Immunodepression Virus serology.
  • Hypersensitivity to deferiprone.
  • Patients with agranulocytosis or with a history of agranulocytosis.
  • Patients taking a treatment at risk of agranulocytosis (clozapine, Closaril®/Leponex®).
  • Pregnant or breastfeeding women or women of childbearing potential not taking highly effective contraception.
  • Kidney or liver failure.
  • Other serious diseases.
  • Inability to provide informed consent.
  • +9 more criteria
