Primary Outcome Measures:

To evaluate the effect of SB-509 on progression of the disease in subjects with ALS, as measured by the ALS Functional Rating Scale -Revised (ALSFRS-R). [ Time Frame: 11 months ]

Secondary Outcome Measures:

To evaluate a) the effect of SB-509 on Forced Vital Capacity, Neurophysiologic Index, Manual Muscle Test, and survival. b) safety and tolerability of SB-509 in ALS. c) stem cell mobilization in subjects with ALS receiving SB-509. [ Time Frame: 11 months ]

Arms	Assigned Interventions
Active Comparator: Cohort 1 SB-509 drug administration via IM injection of neck, arms, and legs	Drug: SB-509 Intramuscular injection of 60 mg of SB-509. Two doses on Day 0 and Day 90.
Active Comparator: Cohort 2 SB-509 drug administration via IM injection of legs	Drug: SB-509 Intramuscular injection of 60 mg of SB-509. Two doses on Day 0 and Day 90.

Detailed Description:

SB-509 contains the gene (DNA—a kind of biological "blueprint") for a protein. When a study doctor injects SB-509 into the muscles of your neck, arms and/or legs, the drug enters the muscle and nerve cells around the injection sites and causes these cells to make a protein. This protein causes your cells to increase production of one of your own protein called vascular endothelial growth factor(VEGF-A), which may improve the structure and function of nerves and muscles. In addition, there are changes in the levels of 28 additional proteins in your cells. These proteins function to promote the growth of cells, are structures in cells, help synthesize products, and affect immune cells, and some have unknown functions. This increase in your own VEGF proteins may protect and repair the damaged nerves and muscles caused by ALS.

Eligibility


Ages Eligible for Study:	18 Years to 85 Years (Adult, Senior)
Sexes Eligible for Study:	All
Accepts Healthy Volunteers:	No

Criteria

Inclusion Criteria:

Male or female between the ages of 18 and 85 with clinical diagnosis of ALS
Forced Vital Capacity (FVC) > 60% of predicted
Less than 3 years of ALS since the onset of the first symptom with clinical evidence of limb muscle atrophy and weakness.
Subjects taking Riluzole must have been at a stable dose for at least 30 days with no evidence of toxicity
Female of childbearing potential and male of child-creating potential must agree to use a medically acceptable physical barrier (condom, diaphragm, and cervical cap) through the treatment phase and for at least 30 days after the last study treatment.

Exclusion Criteria:

Women who are pregnant or currently breast-feeding
Dependent upon invasive or non-invasive artificial ventilation
Patients with bulbar onset ALS or with other active neuromuscular/ neurodegenerative diseases.
Type 1 or Type 2 diabetes.
Evidence of chronic or active heart, liver, kidney, or lung diseases, or Age-related macular degeneration.
Current or history of known immune or immunodeficiency disorders
Patients with cognitive impairment with significant decision making incapacity, or major depression, or schizophrenia, or dementia (e.g. Alzheimer's disease).
Malignancy or history of malignancy, except it has been in complete remission for at least 5 years
Pre-cancerous conditions (e.g. Barrett's Esophagus, dysplasias) or benign tumors which have the potential for significant growth due to VEGF stimulation.
