First, the investigators will determine the safety of a 36 month regimen of Leukine administered as a weight-based dose at 3 µg/kg/day for 5 days (week), followed by a 2-day holiday (weekend). This 36 month (n=10) pilot study will extend the prior 2 month observation tests towards the goal of assessing the safety of Leukine for treatment of Parkinson's disease (PD). Clinical signs and symptoms will be measured by personal well-being, physical, and neurological examinations (UPDRS Parts I, II, III, and IV assessments) and blood tests (CBC with differential, total T cell count, and a comprehensive metabolic sera panel). Second, we will assess regimen tolerability administered in a dose reduction, from 6 µg/kg/day without interruption, to 3 µg/kg/day with 2 day drug holidays. The investigators will examine over a time of 36 months, effects of treatment on defined adaptive immune deficits in PD as measured by analysis of peripheral blood mononuclear cells collected before, during, and after cessation of Leukine administration. Individual T cell parameters will be assessed and will include links between T cell function and subset analyses and clinical neurological signs and symptoms. In addition, the functional stability of the immune deficits will be assess in PD by examining T cell subsets in PD patients in this study against prior results. The investigators will also determine whether the immune deficits of PD are consistent during baseline data collection, and the potential Leukine-induced motor control and mobility improvements will be determined by UPDRS part I, II, III, and IV scores off treatment and on treatment.

Not pregnant, not breastfeeding, and not planning on becoming pregnant during the study; 2. Not of childbearing potential, defined as one who has been postmenopausal for at least 1 year and with follicle stimulating hormone (FSH) levels in the laboratory defined postmenopausal range, or has been surgically sterilized, or has had a hysterectomy at least 3 months prior to the start of this trial; or 3.

Effective methods of avoiding pregnancy are contraceptive methods used consistently and correctly (including implantable contraceptives, injectable contraceptives, oral contraceptives, transdermal contraceptives, intrauterine devices, diaphragm with spermicide, male or female condoms with spermicide, or cervical cap), abstinence, or a sterile sexual partner. 7. Must be stage 4 or less according to the Hoehn and Yahr scale Exclusion Criteria: - 1. Atypical features indicative of a Parkinson-Plus disorder (Progressive Supranuclear Palsy (PSP), Multiple System Atrophy (MSA), Corticobasal Degeneration (CBD)) including cerebellar signs, supranuclear gaze palsy, apraxia and other cortical signs, or prominent autonomic failure 2. Neuroleptic treatment at time of onset of parkinsonism 3. Active treatment with a neuroleptic at time of study entry 4. History of repeated strokes with stepwise progression of parkinsonism 5. History of repeated head injury 6. History of definite encephalitis 7. More than one blood relative diagnosed with PD 8. Prominent gait imbalance early in the course (< 5 years) 9. Mini-mental state examination score <26 10. Hematological malignancy or coagulopathy 11. Abnormal blood analyses: hematocrit <30; WBC>11.5; clinically significant laboratory data (e.g. alanine aminotransferase [ALT] or aspartate aminotransferase [AST] 3x the upper limit of normal [ULN]), or any abnormal laboratory value that could interfere with the assessment of safety in the judgment of the investigator; significant abnormalities on the clinical examination, vital signs, and clinical chemistry or hematology results (excluding findings of Parkinson's disease), that may interfere with the study or present a safety risk for the subject as judged by the clinical investigator charged in the care of study participants 12. Serious medical illness or co-morbidity that may interfere with participation in the study 13. Brain surgery for parkinsonism (DBS, cell implantation, gene therapy) 14. History of an autoimmune disorder or systemic inflammatory disorder deemed significant by physician 15. Immunostimulatory or immunosuppressive treatment (including amphet-amines or systemic corticosteroids) within 90 days 16. Exclusively unilateral parkinsonism for longer than 3 years 17. Known hypersensitivity to GM-CSF, yeast-derived products 18. Current lithium treatment 19. Individuals with current diagnoses of alcohol or substance abuse/dependence 20. Anyone who is not appropriate for participation in this research protocol as deemed by the principal or co-investigator 21. Anyone who has previously been treated with GM-CSF as an immunomodulatory therapy 22. Anyone with poor venous access |

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Incidence of Treatment-Associated Adverse Events | The safety of Leukine administration in PD will be examined by documenting abnormal results from CBC with differential, total T cell count, or comprehensive metabolic panel analyses; abnormal physical and or neurological exam findings; abnormal levels of antibodies to GM-CSF; clinically increasing Unified Parkinson's disease Rating Scale (UPDRS) part I, II, III, and IV scores as determined by the examining physician; and other adverse events. These safety assessments will be made every four weeks. | monthly during the course of treatment, up to 36 months, followed by 1 month drug cessation | |
Secondary | Determination of Immune Cell Phenotype | Measurements will include change in CD45RO+ or FAS+ frequencies in CD4+ T cells; change in CD31+ frequencies in CD4+ T cells, Teff or Treg subsets; change in ItgB7+ frequencies in CD4+ T cells or the Teff subset; change in ItgB4B7+ frequencies in CD4+ T cells or the Treg subset; change in CD27+ frequencies in CD4+ T cells, Teff or Treg subsets, change in CCR7+ frequencies in CD4+ T cells, Teff or Treg subsets; change in FoxP3+ frequencies in CD4+ T cells, Teff or Treg subsets; change in CD34, CD117, or CD135 levels; change in DNA methylation status. The measurements will be combined to determine overall changes in immune cell frequency and T cell subset phenotype both on and off treatment. | 36 months of treatment, followed by 1 month drug cessation | |
Secondary | Determination of Immune Cell Number | Measurements will include changes in levels of lymphocytes or CD4+ T cells, as well as T cell, B cell, and bone marrow progenitor subsets. | 36 months of treatment, followed by 1 month drug cessation | |
Secondary | Determination of Immune Cell Function | Measurements will include changes in T cell function via proliferation and suppression assays and/or changes in B cell function via antibody production assessments. | 36 months of treatment, followed by 1 month drug cessation |
