Clinical Trial Summary

Traditionally amantadine is used at the beginning of Parkinson Disease (PD) treatment in the early stages of the disease, as a modest antiparkinsonian symptomatic treatment. This treatment is usually maintained for no more than the first few months of management, before resorting to drugs deemed more effective as dopamine agonists and lévo-DOPA (L-DOPA). A more modern use of the drug is at a more advanced stage of PD when dyskinesia are already established and become disabling for the patients. There is no data between these two extremes of life stages of Parkinsonism. However, the mechanisms of action of amantadine and the pathophysiology of the motor complications induced by L-DOPA, in particular dyskinesia suggest that the early and prolonged use of amantadine in the early years of management, before L-DOPA-induced dyskinesia have already emerged, should have a positive impact on long-term occurrence and fate of these symptoms, possibly through a glutamatergic mechanism of brain plasticity-of the "disease modification" type.

Description:

Traditionally amantadine is used at the beginning of Parkinson Disease (PD) treatment in the early stages of the disease, as a modest antiparkinsonian symptomatic treatment. This treatment is usually maintained for no more than the first few months of management, before resorting to drugs deemed more effective as dopamine agonists and lévo-DOPA (L-DOPA). A more modern use of the drug is at a more advanced stage of PD when dyskinesia are already established and become disabling for the patients. There is no data between these two extremes of life stages of Parkinsonism. However, the mechanisms of action of amantadine and the pathophysiology of the motor complications induced by L-DOPA, in particular dyskinesia suggest that the early and prolonged use of amantadine in the early years of management, before L-DOPA-induced dyskinesia have already emerged, should have a positive impact on long-term occurrence and fate of these symptoms, possibly through a glutamatergic mechanism of brain plasticity-of the "disease modification" type.

The primary purpose of this study is to demonstrate that early introduction of treatment with amantadine (200 mg / d) in the early years of therapeutic care, that is to say during the "honeymoon" of levodopa (early phase of disease <3 years of diagnosis <1 year of L-dopa and lack of complications of levodopa therapy) decreases the rate of subjects with abnormal involuntary dyskinetic movements after 18 months of follow-up.

Eligibility

Inclusion Criteria:

• Age over 35 years,

• Patients having signed an informed consent before any specific study procedures,

• Patients having a health Insurance Coverage (according to local regulatory requirements),

• Patients suffering from idiopathic Parkinson's disease meeting the definition criteria of the UKPD Brain Bank (Gibb and Lees, 1988),

• Parkinson's disease diagnosed for <3 years,

• Patients receiving treatment with L-DOPA from <1year,

• Lack of complications of levodopa therapy

• Patients receiving a stable antiparkinsonian treatment that may involve, in addition to L-DOPA, a dopamine agonist, a monoamine oxidase-B (MAO-B) or a catecholamine O-methyl transferase (COMT) inhibitor, an anti-cholinergic for at least 2 months before enrollment and in whom we presume it will be possible to maintain this treatment unchanged during the study period (except the dose of L-dopa which can be adjusted during the study after the third month of Phase 1).
