E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary efficacy objective of this study is to demonstrate the efficacy of nabilone concerning non-motor symptoms of patients with Parkinson´s disease, based on the change from baseline to Week 4/Termination visit in the MDS-UPDRS Part I. |
|
E.2.2 | Secondary objectives of the trial |
to evaluate the effect of nabilone on motor symptoms of PD and on different domains of NMS by means of the change from baseline to Week 4 in the following assessments:
MDS – Unified Parkinson´s Disease Rating Scale
Non Motor Symptoms Scale
mood/anxiety domain of MDS-UPDRS Part I (items 1.3 and 1.4)
different other domains of NMSS & MDS-UPDRS part I
Hospital anxiety and depression scale
Parkinson´s Disease Questionnaire – 39
Montreal Cognitive Assessment
Epworth Sleepiness Scale
Fatigue Severity Scale
Visual Analog Scale of Pain
King's Parkinson's disease pain scale
Questionnaire for Impulsive-Compulsive Disorders in Parkinson’s Disease–Rating Scale
Clinical Global Impression – Global Improvement scale at Termination Visit
Safety and Tolerability objectives on the Overall course of the study
Exploratory Objective: Eye-tracking evaluation in PD patients taking nabilone or placebo at the Screening and the Termination visit |
