Intranasal Human FGF-1 for Subjects With Parkinson's Disease

1. Males and females 40-80 years of age, inclusive, with a diagnosis of Parkinson's disease. At screening, a further confirmation of the diagnosis of Parkinson's disease will be made by the PI in accordance with accepted medical practices.
2. Female subjects of non-childbearing potential or if of child-bearing potential, on birth control deemed acceptable to the Principal Investigator (PI).
3. 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. Ability to complete the study in compliance with the protocol in the opinion of the Principal Investigator.
