Design outcomes

Primary

MeasureTime frameDescription
Motor symptoms as assessed by the Movement Disorder Society's Unified Parkinson's Disease Rating Scale (MDS-UPDRS)18 monthsChange from baseline in the MDS-UPDRS. The MDS-UPDRS contains 4 subscales: Part I, non-motor aspects of experiences of daily living (13 items); Part II, motor aspects of experiences of daily living (13 items); Part III, motor examination (33 scores based on 18 items); Part IV, motor complications (6 items). The rating for each item, or sub-item, is from 0 (normal) to 4 (severe). The total score for each Part is obtained from the sum of the corresponding item scores.
MSA symptoms/signs as assessed by the Unified Multiple System Atrophy Rating Scale (UMSARS)18 MonthsChange from baseline in the Unified Multiple System Atrophy Rating Scale (UMSARS) and compared to placebo. UMSARS total scores range from 0-104 points with higher scores indicating greater severity of impairment.

Secondary

MeasureTime frameDescription
Change in the quality of life as measured by Parkinson's Disease Questionnaire (PDQ-39)18 monthsChange from baseline in the Parkinson's Disease Questionnaire (PDQ-39). PDQ-39 is a self-reported 39-item questionnaire designed to measure health related quality of life in Parkinson's Disease patients. It provides scores in 8 domains: mobility, activities of daily living, emotions, stigma, social support, cognitive function, bodily discomfort and communication, as well as a summary index score for quality of life.
Change in the quality of life as measured by Multiple System Atrophy Quality of Life (MSA-QoL)18 monthsChange from baseline in the Multiple System Atrophy Quality of Life (MSA-QoL) scale. MSA-QoL is a self-reported questionnaire that measures MSA impact in day to day activities. Scale consists of 40 items with a five response option format (0 - no problem to 4 extreme problem) and a "not applicable" response option.
