Signed and dated informed consent form, which meets all current regulatory criteria. 4. No evidence of proliferative retinopathy or significant non-proliferative retinopathy. 5. Subjects can be on a stable medical therapy for their Parkinson's disease prior to entering the study, as documented by their medical history. Other medications that are acceptable will be at the discretion of the Principal Investigator. At screening it will be stressed that, if possible, subjects should not add, switch or increase doses of any Parkinson's disease medications during the duration of the study. 6. Test drug administration and administration of questionnaires to measure motor function and mental status will be performed in the "on" state. 7.

Females who are pregnant at screening or of child-bearing potential and not using an acceptable form of birth control. 2. History of allergy or sensitivity to heparin. 3. Significant history or current evidence of chronic infectious disease or other medical conditions that, in the opinion of the Investigator, would compromise the safety of the subject or the study. 4. Subjects with malignancies or a history of malignancies (with the exception of basal cell carcinoma or squamous cell carcinoma of the skin) will be excluded from the study. 5. Clinically significant ECG abnormalities that in the opinion of the PI could potentially put the patient at risk. 6. Subjects with an HbA1C of \>7.5% 7. Uncontrolled hypertension with systolic blood pressure \>165 mmHg or diastolic blood pressure \>100 mmHg despite diet, exercise or a stable dose of an appropriate antihypertensive therapy for at least 3 months 8. Significant hypotension with systolic blood pressure \<85 mmHg or diastolic blood pressure \<55 mmHg. 9. Total fasting serum cholesterol \>220 mg/dL. 10.
