- Incidence of acute adverse events [ Time Frame: up to 4 weeks post treatment ]An adverse event is defined any untoward or undesirable medical occurrence in the form of signs, symptoms, abnormal findings, or diseases that emerge or worsen relative to baseline (i.e., if present upon study entry) during the study regardless of causal relationship to the study drug
- Incidence of delayed adverse events [ Time Frame: 48 weeks post treatment ]An adverse event is defined any untoward or undesirable medical occurrence in the form of signs, symptoms, abnormal findings, or diseases that emerge or worsen relative to baseline (i.e., if present upon study entry) during the study regardless of causal relationship to the study drug.
- Severity of adverse events [ Time Frame: 4 weeks post-treatment ]The severity of adverse events will be graded into the following categories: mild, moderate, and severe.
- Relationship of adverse events to study drug [ Time Frame: 4 weeks post-treatment ]The relationship of adverse events to study drug will be graded into the following categories: probable, possible, unlikely, unrelated.
- Incidence of serious adverse events (SAE) [ Time Frame: 48 weeks post-treatment ]SAE is defined as adverse events that result in death, life threatening adverse experiences, hospitalization, new or prolonged disability/incapacity.
- Change in sensory and motor function following completion of treatment as measured by the American Spinal Injury Association (ASIA) Impairment Scale (AIS) [ Time Frame: baseline, 96 weeks ]The ASIA Impairment Scale describes a person's functional impairment (both motor and sensory) as a result of their spinal cord injury. The scale has 5 levels, ranging from A (complete) to E (normal).
- Change in sensory and motor function following completion of treatment as measured by motor evoked potentials (MEP) [ Time Frame: baseline, 96 weeks post-treatment ]Motor Evoked Potentials (MEP) are electrical responses recorded either from muscles, or from axons of the descending motor tract, in response to electrical or magnetic stimulation of nervous system structures that govern movement. While there are many different methods for stimulation and recording, the most common approach involves transcranial electrical stimulation of the motor pathway, using subdermal needle electrodes positioned in the scalp above primary motor cortex.
- Change in sensory and motor function following completion of treatment as measured by Somatosensory Evoked Potentials (SSEPs) [ Time Frame: baseline, 96 weeks post-treatment ]Somatosensory Evoked Potentials (SSEPs) are electrical responses recorded from the nervous system following electrical stimulation of a peripheral nerve. For example, stimulation of the median nerve at the wrist produces electrical activity that travels along the sensory pathway on its way to the brain. This activity can be recorded with electrodes positioned along that pathway.
- Number of subjects who develop a new pathologic mass at the spinal cord area of injection or anywhere along the spinal cord. [ Time Frame: approximately 96 weeks post-treatment ]Patients will undergo Magnetic Resonance Imaging of the spine and the spinal cord with and without contrast.
- Change in number of red blood cells following treatment [ Time Frame: baseline, 4 weeks post-treatment ]Blood will be drawn in order to monitor for markers of systemic inflammation. The normal range of red blood cells varies slightly between laboratories but is generally between 4.2 - 5.9 million cells/cmm. This can also be referred to as the erythrocyte count and can be expressed in international units as 4.2 - 5.9 x 10^12 cells per liter.
- Change in white blood cells with differential following treatment [ Time Frame: baseline, 4 weeks post-treatment ]Serological test - Automated white cell differential. A machine generated percentage of the different types of white blood cells, usually split into granulocytes, lymphocytes, monocytes, eosinophils, and basophils.
- Change in number of platelets following treatment [ Time Frame: baseline, 4 weeks post-treatment ]Serological test: Platelets are not complete cells, but actually fragments of cytoplasm from a cell found in the bone marrow called a megakaryocyte. Platelets play a vital role in blood clotting. Normal range varies slightly between laboratories but is in the range of 150,000 - 400,000/ cmm (150 - 400 x 10^9/liter).
- Change in Serum C-Reactive Protein (CRP) [ Time Frame: baseline, 4 weeks post-treatment ]Serological test: C-reactive protein (CRP) is produced by the liver. The level of CRP rises when there is inflammation throughout the body. It is one of a group of proteins called acute phase reactants that go up in response to inflammation. C-reactive protein is measured in milligrams of CRP per liter of blood (mg/L). Normal CRP levels are below 3.0 mg/dL.
- Change in Erythrocyte Sedimentation Rate (ESR) [ Time Frame: baseline, 4 weeks post-treatment ]Serological test. The erythrocyte sedimentation rate (ESR) is the rate at which red blood cells sediment in a period of one hour. It is a common hematology test, and is a non-specific measure of inflammation. The normal range is 0-22 mm/hr for men and 0-29 mm/hr for women.
- Change in Blood Urea Nitrogen (BUN) [ Time Frame: baseline, 4 weeks post-treatment ]Serological test - basic metabolic panel. A blood urea nitrogen (BUN) test measures the amount of nitrogen in the blood that comes from the waste product urea. Urea is made when protein is broken down in the body. Urea is made in the liver and passed out of the body in the urine. A BUN test is done to see how well the kidneys are working. Results of the blood urea nitrogen test are measured in milligrams per deciliter (mg/dL).
- Change in Creatinine [ Time Frame: baseline, 4 weeks post-treatment ]Serological test - basic metabolic panel. Creatinine is a waste product produced by muscles from the breakdown of a compound called creatine. Almost all creatinine is filtered from the blood by the kidneys and released into the urine, so blood levels are usually a good indicator of how well the kidneys are working. Results are reported in mg/dL.
- Change in Sodium [ Time Frame: baseline, 4 weeks post-treatment ]Serological test - basic metabolic panel. A sodium blood test allows the doctor to see how much sodium is in the subject's blood. It helps maintain normal blood pressure, supports the work of your nerves and muscles, and regulates your body's fluid balance. A normal sodium level is between 135 and 145 milliequivalents per liter (mEq/L) of sodium.
- Change in Potassium [ Time Frame: baseline, 4 weeks post-treatment ]Serological test - basic metabolic panel. The normal potassium level in the blood is 3.5-5.0 milliEquivalents per liter (mEq/L).
- Change in Chloride [ Time Frame: baseline, 4 weeks post-treatment ]Serological test - basic metabolic panel. The normal blood reference range of chloride for adults in most labs is 96 to 106 milliequivalents (mEq) per liter.
- Change in Aspartate Aminotransferase (AST) [ Time Frame: baseline, 4 weeks post-treatment ]Serological test - basic metabolic panel. Inflamed or injured liver cells leak higher than normal amounts of certain chemicals, including liver enzymes, into the bloodstream, which can result in elevated liver enzymes on blood tests. The reference range for aspartate aminotransferase (AST) is as follows: Males: 6-34 IU/L, Females: 8-40 IU/L.
- Change in Glucose [ Time Frame: baseline, 4 weeks post-treatment ]Serological test - basic metabolic panel. For a subject without diabetes, a fasting blood sugar on awakening should be under 100 mg/dl.
- Change in Carbon Dioxide [ Time Frame: baseline, 4 weeks post-treatment ]Serological test - basic metabolic panel. The normal range for carbon dioxide is 23 to 29 mEq/L (milliequivalent units per liter of blood).
