Eligibility Criteria

Age40 Years - 75 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Males and females, 40 to 75 years of age (inclusive)
  • Diagnosis of PD, consistent with United Kingdom Brain Bank Criteria
  • Motor responsiveness to dopaminergic therapy, demonstrated by improvement in Movement Disorder Society - Unified Parkinson's Disease Rating Scale (MDS-UPDRS III score)
  • Disease duration from diagnosis of ≥4 years
  • An average of ≥3 hours of OFF time (that is, periods of insufficient control of motor PD symptoms) per day over 3 consecutive days as confirmed by the PD Diary
  • A stable, optimal regimen of Parkinson's medications including levodopa for at least weeks prior to screening evaluation. Participants must have a minimum duration of levodopa treatment of ≥1 year
  • In the judgment of the Investigator, stable Parkinson's features and symptoms for at least 4 weeks prior to screening evaluation
  • Agrees to defer any elective neurological surgery, including deep brain stimulation or ablation procedure for PD, levodopa or apomorphine infusion, or the addition of new dopaminergic formulations until after the study is completed, if medically appropriate
  • Ability to travel to study visits

You may not qualify if:

  • Atypical or secondary parkinsonism, including but not limited to symptoms believed to be due to trauma, brain tumor, infection, cerebrovascular disease, other neurological disease, or to drugs, chemicals, or toxins, as determined by the Investigator
  • Montreal Cognitive Assessment (MoCA) score \<26
  • New or unstable psychiatric conditions (psychosis, depression) within 1 year of screening
  • Brain imaging abnormalities in the striatum or other regions that would substantially increase risk of surgery
  • Contraindication to magnetic resonance imaging (MRI) and/or gadolinium-based contrast agents
  • Prior brain surgery, infusion therapies or planned treatments that could complicate the study procedure or negatively impact study evaluations as determined from participant interview, screening MRI, or medical records
  • History of malignancy other than treated carcinoma in situ within 3 years of screening evaluation
  • Prior gene transfer, current treatment with any investigational agent (drug or device) within 2 months of screening evaluation, or participation or plans to participate in another research study
  • Severe, biphasic and/or uncontrolled dyskinesia
  • Disabling or uncontrolled impulse control disorders
