Brief Summary

Progressive supranuclear palsy (PSP) is a rare neurodegenerative disease from the parkinsonian syndrome group. It represents 5 to 10% of all parkinsonian syndromes and affects 3,000 to 10,000 persons in France. PSP is characterised by a doparesistant parkinsonism with axial signs such as early gait instability and falls, oculomotor signs such as a vertical gaze palsy, dysphagia and dysarthria, and both cognitive and behavioural disturbances. The latter predominantly manifest as psycho-motor slowness, apathy and frontal executive deficits. Swallowing impairments and falls may lead to life-threatening situations and death occurs 6-9 years after disease onset. Apart from L-dopa which may transiently and inconsistently improve motor symptoms no effective symptomatic, disease-modifying or neuroprotective therapy is presently available to reduce disability in any way. Therefore these patients often receive mostly non-medical care such as physiotherapy and speech therapy. In addition to dopaminergic degeneration there is evidence of cholinergic deficits in PSP correlated with gait and balance impairments . This stands in contrast with the limited number of studies of cholinergic augmentation strategies in PSP. Trials of cholinesterase inhibitors in PSP have produced rather conflicting results: donepezil improves cognition but deteriorates some motor functions whereas a case series of 5 PSP patients treated with rivastigmine found an improvement in several cognitive aspects and no deterioration of motor functions .On the other hand in Parkinson's disease there is convincing evidence of a positive effect of rivastigmine on cognition , apathy and falls Investigators' hypothesis is that rivastigmine (an acetyl- and butyryl-cholinesterase inhibitor) may reduce gait and postural impairment in PSP and may therefore limit the number of falls and their consequences both in terms of injuries sustained (fractures etc...) and on the patients' autonomy. In addition investigators hypothesise that rivastigmine may also reduce the cognitive and behavioural impairment associated with PSP. Taken together these improvements are likely to produce a significant effect on the patients' quality of life and their caregiver burden.

Outcome Measures

Primary Outcomes (1)

  • Efficacy will be assessed at 4 months as the change from baseline of the number of falls and near falls over the past 2 week

    Efficacy will be assessed at 4 months as the change from baseline of the number of falls and near falls over the past 2 weeks using fall postcards sent weekly and filled daily by the subject and caregiver. The number of falls and near-falls will be expressed both as the total number of occurrences over that period and as the number of occurrence adjusted to the distance and number of hours walked (assessed using continuous accelerometer recordings)

    baseline, 2 weeks, 4 months

Secondary Outcomes (9)

  • Change from baseline at 4 months measured by the global ans sub scores of the PSPRS scale (Progressive Supranuclear Palsy Rating Scale)

    Baseline and 4 months

  • Change from baseline at 4 months measured by the Clinical Global Impression scale (patient and caregiver)

    Baseline and 4 months

  • Apathy assessed using the Lille Apathy Rating Scale (LARS) both subject and caregiver versions

    Baseline and 4 months

  • Assessment of the Quality of life of patient using the PSP-Quality of Life Scale (PSP-QoL)

    Baseline and 4 months

  • Assessment of the Quality of life of patient using the EQ-5D

    Baseline and 4 months

  • +4 more secondary outcomes

Study Arms (2)

Rivastigmine

ACTIVE COMPARATOR

Subject will receive a treatment of Rivastigmine twice daily during 24 weeks of treatment. Study drug will be administered orally. Sufficient test drug will be dispensed to subjects or their caregivers at each study visit to allow twice daily dosing until the next scheduled study visit

Drug: Rivastigmine

Placebo

PLACEBO COMPARATOR

Subject will receive a placebo twice daily during 24 weeks of treatment. Study drug will be administered orally. Sufficient test drug will be dispensed to subjects or their caregivers at each study visit to allow twice daily dosing until the next scheduled study visit

Drug: Placebo

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Aged 41 to 80 years at the time of screening
  • Judged by site investigator to be able to comply with gait/balance and neuropsychological evaluations at baseline and throughout the study
  • Able to ambulate independently or with assistance (cane)
  • Score ≥ 20 on the mini-mental state examination (MMSE) at screening
  • A reliable caregiver - defined as a person having frequent contact with subject (≥ 3 hours per day) and willing to fill the fall diaries and monitor study medication compliance and the subject's health and concomitant medication throughout the study - must accompany the subject to all visits.
  • A fall or near fall rate ≥ 2/week in average (estimated through interview at screening and confirmed during a 2-week period between screening and baseline using fall postcards).
  • Any parkinsonian medication taken by the subject must be stable in dose for 4 weeks prior to screening and must remain stable for the duration of the study
  • Stable on all other chronic medications for 4 weeks prior to screening
