This study has been completed.

This is a French national trial, conducted using a double-blind, placebo-controlled, randomised design involving 15 centers and 88 patients of both sexes.

The primary objective of the trial is to evaluate the effect of a selective inhibitor of serotonin reuptake, the Fluoxétine, at a higher dose (40 mg/day) than usually recommended for depressed patients, after three months in patients suffering from an atypical Parkinson's disease called Multiple System Atrophy, compared to the placebo effect.

Secondary objectives of the trial are the evaluation of the effects of Fluoxétine after six weeks at the dose of 20 mg/day, after six months at the dose of 40mg/day, and assess the effects on mortality, quality of life, autonomic disorders, particularly orthostatic hypotension, mood and others symptoms such as sleep, apathy, pain and fatigue.

Primary Outcome Measures:
  • primary efficacy endpoint [ Time Frame: 3 months ]
    The primary efficacy endpoint is the comparison of scores in Parts I and II of the UMSARS scale between the visit V0 and V2 (i.e. after 3 months of treatment at the dose of 40mg/day).

Secondary Outcome Measures:
  • secondary efficacy endpoints [ Time Frame: 6 weeks, 3 months or 6 months ]
    • comparison of scores in Parts I and II of the UMSARS scale between the visit V0 and V3, i.e. after 6 months of treatment at the dose of 40mg/d
    • comparison of scores in Parts I and II of the UMSARS scale between the visit V0 and V1, i.e. after 6 weeks of treatment at the dose of 20mg/d
    • rate of mortality
    • score of SCOPA AUT scale - assessment of symptomes related to the dysautonomic affect
    • score of Part III of UMSARS scale - assessment of orthostatic hypotension
    • score of Beck scale - assessment of depression
    • score of Schrag scale - assessment of health-related quality of life

Enrollment: 87

Study Completion Date: September 2011
Primary Completion Date: June 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: the fluoxetine group
Multiple System Atrophy's patients with fluoxétine
20mg/d, oral administration for 6 weeks, then 40mg/d for 4 months.
Other Name: PROZAC®
Placebo Comparator: the placebo group
Multiple System Atrophy's patients with placebo
20mg/d, oral administration for 6 weeks, then 40mg/d for 4 months.
Other Name: PROZAC®

Detailed Description:
Fluoxetine is first introduced in dose of 20 mg/day and after six weeks the dose is increased to 40 mg/day. If patients have side effects at the dose of 40 mg/day, the dose may be reduced at 20 mg/day. Assessment visits will be conducted at 6 weeks, 3 months, and 6 months of treatment. After 6 months, trial's treatment with fluoxetine is discontinued gradually. A new assessment will be conducted one month after the end of treatment. The expected results are the demonstration of improved scores of the scale UMSARS after 3 and 6 months in the fluoxetine group compared to the placebo group.

Ages Eligible for Study:   30 Years to 80 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Female or Male Patient with Multiple System Atrophy's disease diagnosed according to international consensus criteria (Gilman's criteria)
  • Patient between 30 and 80 years of age
  • Patient not presenting a cognitive problem that could impair the comprehension of the patient and his participation in the protocol
  • Patient receiving an anti-parkinsonian treatment (if applicable) at a stable dose for at least 2 months before entering the study, and with the expectation that the treatment will remain unchanged throughout the course of the patients participation in the trial
  • Patient receiving a symptomatic treatment of autonomic disorders (if applicable) at a stable dose for at least 2 months before entering the study, and with the expectation that the treatment will remain unchanged throughout the course of the patient participation in the trial
  • Signed informed consent obtained
  • Patient eligible for social security (specific requirement under French law)

Exclusion Criteria:

  • Patient presenting major swallowing problems as he will not take capsule
  • Patient already receiving a selective inhibitor of serotonin reuptake or other antidepressant, or patient having received one in the 3 months preceding the start of the study
