- Primary Outcome Measures
Name Time Method The incidence of Treatment-Emergent Adverse Events (TEAE) and Serious Adverse Events (SAE) assessed clinically by physical and neurological examinations 3 years Number of TEAE and SAE's reported post-treatment.
- Secondary Outcome Measures
Name Time Method MSA symptoms/signs as assessed by the Unified Multiple System Atrophy Rating Scale (UMSARS) 12 months Change 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.
Change in the quality of life as measured by Multiple System Atrophy Quality of Life (MSA-QoL) 12 months Change from baseline and compared to placebo 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.
Change in striatal dopamine transporter binding as measured by [123-I] Ioflupane 12 months Percent and absolute change in ratio of specific to non-specific binding of 123I FP-CIT to DaT from baseline and compared to placebo by Single Photon Emission Computed Tomography (SPECT) dopamine transporter (DaT) imaging
