|Condition or disease||Intervention/treatment||Phase|
|Parkinson Disease||Drug: 1. Tesofensine (NS 2330)||Phase 2|
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
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.
