Primary Completion Date: February 2005 (Final data collection date for primary outcome measure)
Detailed Description:

This is a randomized, double-blind, placebo-controlled, five parallel groups efficacy and safety exploratory of tesofensine versus placebo in levodopa treated Parkinson patients with motor fluctuations.

Patients will be treated either with one of the 4 doses of tesofensine (0.125mg, 0.25mg, 0.50 mg or 1.0 mg) or with placebo, once daily, over 14 weeks.

The two co-primary efficacy endpoints are the change in off-time and the change in the Unified Parkinson Disease Rating Scale (UPDRS) II+III total score

Study Hypothesis:

The null hypothesis is that there is no difference between placebo and tesofensine.

The alternative hypothesis is that treatment with tesofensine is superior to treatment with placebo.


For the primary comparison between tesofensine and placebo, change in percentage off-time during waking hours will be based on reports from patient's diary (completed at day -3 and day-2 prior to the study visits) and change in the UPDRS II+III will be based on UPDRS II averaged for on and off periods and UPDRS III evaluated at on periods during the study visits.


Ages Eligible for Study:   42 Years to 80 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Main inclusion criteria:

  • Male or female patient with idiopathic Parkinson Disease (PD) diagnosed for at least 2 years.
  • Patient aged 40 years or over at time of diagnosis of PD and not older than 80 years at screening visit.
  • Modified Hoehn and Yahr stage of II to III at "on" time.
  • Treatment with Levodopa at an optimised dose, 4 to 8 times per day, this dose being stable for at least 4 weeks prior to screening visit.
  • Motor fluctuations, with 2.0 to 6.0 cumulative hours of "off" time every day during waking hours, documented from patient's diary completed for 2 consecutive days before baseline visit.

Main exclusion criteria:

  • Neuropsychiatric exclusions: Non-idiopathic PD, dementia (Mini Mental State Exam <26), history of psychosis, history or current Axis I or Axis II mental disorder according to DSM-IV, etc
  • Other medical exclusions, like ECG abnormalities, hypotension and/or symptomatic orthostatic hypotension, some abnormal laboratory parameters (e.g. severe renal impairment), etc
  • Pharmacological exclusions, e.g. selegiline within 8 weeks prior to screening visit, regular use of anti-depressant drugs, any medication with central dopaminergic antagonist activity, etc
