Exclusion Criteria:

• Subjects who cannot tolerate a venipuncture and/or have adequate venous access.
• Inability to ambulate 100 feet independently with or without an assistive device.
• Subjects who have a history of allergy, hypersensitivity, or intolerance to any medications, components, or excipients of the investigational product or procedures, and which cannot be resolved by the staff conducting the study.

• Subjects with a known diagnosis of Atypical Parkinsonian Syndrome e.g.:

  1. Dementia with Lewy Bodies;
  2. Progressive Supranuclear Palsy;
  3. Corticobasal Degeneration;
  4. Multiple System Atrophy;
  5. Other Neurodengerative Conditions.
• Head trauma related to the onset of bradykinesia symptoms.
• History of repeated head injury, hydrocephalus, encephalitis, or cerebral tumors.
• Choreoathetosis
• Any documented abnormality in the brain by CT or MRI, which might contribute to the motor function, e.g., stroke, tumor, or other space-occupying lesions, hydrocephalus, or encephalomalacia.
• Known history of serum or plasma progranulin level < 110.9 ng/mL.
• Disease associated mutation in TDP-34, PGRN, CHMPB2, or VCP genes or any other FTLD Causative genes.
• Intracranial operation, e.g., pallidotomy, thalamotomy, and/or deep brain stiumulation surgery.
• Other known neurodegenerative diseases not underlying the bradykinesia, e.g., Spinocerellar Atropy (SCA), Wilson's Disease, or Amyotrphic Lateral Sclerosis (ALS).
• History of other significant neurological or physciatric disorders including, but not limited to, Alzheimer's disease, Lewy Body Dementia, Prior Disease, stroke, or seizure disorder.
• Psychiatric illness that is unrelated to the Bradykinesia, e.g., severe bipolar or unipolar depression.
• History of neurotoxin exposure.
• History of REM behavior disorder.
• Patients with Hepatocellular Carcinoma (HCC).
• Acute liver failure or episode of hepatic encephalopthy.
• Systolic blood pressure greater than 180 or less than 90 mmHg.
• Diastolic blood pressure greater than 105 or less than 50 mmHg.
• Presence of QTcprolongation or ECG abnormal at screening and judged to be clinically significate by the site investigator.
• Clinically significant cardiovascular disease, e.g., cardiac surgery or myocardial infarction within the last 6 months, unstable angina, congestive heart failure, significant cardaic arrthymia; or cogenitial heart disease.
• Early, symptomatic autonomic dysfunction.
• Any malignancy (other than non-metasticic basal cell carcinoma of the skin) with 5 years of screening.
• Clinically significant lab abnormalities at screening, including creatinine ≥ 2.5 mg/dL, vitam B12 below laboratory normal reference range, or TSH above laboratory normal reference range.
• Current clinically significant hematological, endocrine, cardiovascular, renal, heapatic, gastrointestinal, or neurological disease. For the non-cancerconditions, if the condition has been stable for at least the past year and is judged by the site investigator not to interfere with the patient's participation in the study, the patient may be included.
• A history of alcohol or substance abuse within 1 year prior to screening and deemed to be clinically significant by the site investigator.
• An employee or relative of an employee.
• Subjects who have donated plasma or platelets or had a significant loss of whole blood (480 ml or more) within 30 days.
• Subjects who have received blood or blood products within 30 days prior to screening.
• Treatment with any investigational drugs or device or participation in an investigational drug study within 60 days of screening.
• Women of childbearing potential who are not using at least two forms of medically recognized contraception.
• Female subjects who are pregnant, expecting to become pregnant, or lactating/nursing.
• Any subjects who have a clinically significant abnormal laboratory value.
• Subjects who have been treated with another research product 30 days prior to the screening assessment, or plant to participate in another clinical trial, while in this study. If more than 30 days have passed since participation in another clinical trial, the study staff must ensure that the subject has recovered from any adverse events associated with the research product used.
• Subjects who have a history of any other clinically significant disease or disorder that in the opinion of the Principal Investigator, may place the subject at risk due to participation in the study, or may influence the results of the study.
