Outcome Measures
Primary Outcomes (5)
Grading of adverse Events/Serious Adverse Events (AE's/SAE's)
Grading will be assessed using NCI CTCAE, version 4.03.
Baseline to 3 Years After Gene Transfer
Magnetic Resonance Imaging (MRI)
Safety of VY-AADC01 will be assessed by any clinically significant abnormalities on MRI scans as compared to Baseline.
Baseline to 3 Years After Gene Transfer
Routine physical examinations
Safety of VY-AADC01 will be assessed by routine physical examinations.
Baseline to 3 Years After Gene Transfer
Routine clinical laboratory analysis
Safety of VY-AADC01 will be assessed by routine clinical laboratory analysis.
Baseline to 3 Years After Gene Transfer
Change in Columbia-Suicide Severity Rating Scale (C-SSRS) results
C-SSRS is a standardized suicidal rating system.
Baseline to 3 Years After Gene Transfer
Secondary Outcomes (16)
Change in Parkinson's medications
Baseline to 3 Years After Gene Transfer
Change in motor function using Parkinson Disease Diaries
Baseline to 3 Years After Gene Transfer
Change in motor function using a Stand-Walk-Sit Test
Baseline to 3 Years After Gene Transfer
Change in motor function using Modified Hoehn and Yahr Scale
Baseline to 3 Years After Gene Transfer
Change in motor function using Unified Parkinson's Disease Rating Scale (UPDRS)
Baseline to 3 Years After Gene Transfer

Eligibility Criteria
You may qualify if:
- Diagnosed with idiopathic PD.
- Adequate duration of levodopa therapy.
- Disease duration of at least 5 years or more.
- Modified Hoehn \& Yahr Staging with at least 2.5 hours or more in the OFF state.
- Candidate for surgical intervention because of disabling motor complications.
- UPDRS Part III (total score) of at least 25 in the OFF state.
- Unequivocal responsiveness to dopaminergic therapy.
- Stable Parkinson's symptoms and medications for at least 4 weeks prior to screening evaluation.
- Ability to comprehend and sign the informed consent.
- Normal laboratory values prior to surgery.
- Medically and mentally capable of undergoing and complying with the surgical procedure and protocol requirements.
- Ability to travel to study visits alone or able to designate a caregiver.
- Subject agrees to defer any neurological surgery, including deep brain stimulation, until after completing the 12 month study visit (unless recommended by study neurologist).
- Approved by the Eligibility Review Committee.
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.
- Presence of dementia as defined by a Mattis Dementia Rating Scale - Second Edition (MDRS-2) score of less than 130 at screening.
- Presence or history of psychosis, with the exception of mild, benign hallucinations believed in the judgment of the Investigator to be related to Parkinson's medications.
- Presence of severe depression, as indicated by a BDI-II score greater than 28, or a history of a major affective disorder within 5 years of screening evaluation.
- Active suicidal ideation or suicide attempt within 5 years of screening evaluation.
- History of substance abuse within 2 years of screening evaluation.
- Brain imaging abnormalities in the striatum or other regions that would substantially increase risk of surgery.
- Contraindication to MRI and/or gadoteridol.
- Coagulopathy or inability to temporarily stop any anticoagulation or antiplatelet therapy prior to surgery.
- Prior brain surgery including lesioning procedures, deep brain stimulation, infusion therapies or any other brain surgery.
- Prior gene transfer.
- History of stroke, poorly controlled or significant cardiovascular disease, diabetes, or any other acute or chronic medical condition.
- History of malignancy other than treated carcinoma in situ within 3 years of screening evaluation.
- Clinically apparent or laboratory-detected infection.
- Prior or current treatment with any investigational agent within 2 months of screening evaluation.
