Primary Outcome Measures:
  • Safety as assessed by drug related AEs [ Time Frame: 3 months ]
    Safety as assessed by drug related adverse events

Secondary Outcome Measures:
  • Biomarker assessments as measured in cerebrospinal fluid, blood and urine [ Time Frame: 3 Months ]
  • Clinical Disease State as assessed by the Movement Disorder Society-sponsored revision of the Unified Parkinson's Disease Rating Scale (MDS-UPDRS) [ Time Frame: 3 Months ]
  • Disease morbidity as assessed by composites scales including Non-motor Symptoms Scale (NMSS), PDQ-39 and EQ-5D [ Time Frame: 3 Months ]
  • Cognitive function as assessed by composite scales including MoCA and DRS-2 scales [ Time Frame: 3 Months ]
  • Mood as assessed by composite scales including the BDI and MADRS scales [ Time Frame: 3 Months ]
  • To evaluate changes in pharmacokinetics parameters (cmax) for all treated subjects pre and 3 months post treatment with EPI-589 [ Time Frame: 3 Months ]
  • Safety as evidenced by development of drug related adverse events after treament with EPI-589 [ Time Frame: 3 Months ]

Estimated Enrollment: 40
Study Start Date: March 2016
Estimated Study Completion Date: July 2018
Estimated Primary Completion Date: April 2018 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: EPI-589 500 mg bid
All enrolled subjects will receive treatment with EPI-589
Drug: EPI-589
EPI-589 is a redox active molecule and will be provided in a 250 mg tablet formulation.
Other Name: (R)-Troloxamide quinone

Detailed Description:
This is a within-subject, controlled open-label study seeking to determine if EPI-589 can alter the biochemical signature of PD as assessed by peripheral blood and brain imaging biomarkers. Data will also be collected on disease-relevant clinical measures will be collected.
