Brief Summary

Researchers are conducting this study to learn more about the side effects of bone marrow-derived stem cells when injected into the facet joints for the treatment of painful lumbar facet joint arthropathies.

Detailed Description

Phase I prospective study to determine the safety and feasibility of allogeneic, culture-expanded BM-MSCs in subjects with painful facet-mediated low back pain. Target accrual is 10 subjects with diagnosis of painful lumbar facet joint arthropathy. Eligible subjects will receive a single set of intra-articular bilateral injections of allogeneic, culture-expanded BM-MSCs human, allogeneic, culture expanded, bone-marrow-derived mesenchymal stem cells. Subjects will be evaluated at baseline, treatment day 0, post-operative day 1, post-operative days 3-5, week 2, and months 3, 6, 12, 18 and 24 months post-treatment.

BM-MSC injections for low back pain	Single bilateral intra-articular injection of allogeneic BM-MSCs for lumbar facet joint arthropathy	Single bilateral intra-articular injections of allogeneic BM-MSCs for lumbar facet joint arthropathy

Primary Outcome Measures

Name	Time	Method
Clinical assessment of nature, incidence, and severity of adverse events (AEs)	24 months	Clinical examination face-to-face during follow-up visits
Study personnel assessment of nature, incidence, and severity of AEs	24 months	Subject interview by study personnel
Self-reported assessment of nature, incidence, and severity of AEs	24 months	Spontaneous subject reports

Secondary Outcome Measures

Name	Time	Method
Changes from Baseline evaluated by MRI	24 months	Imaging evaluation by 2 independent radiographic interpretations to determine presence of effusions, bone marrow lesions/peri-articular edema, osteophytes, or any degree of facet synovitis
Oswestry Disability Index (ODI)	24 months	Self-reported index to quantify disability for low back pain. Scores vary from 0 (no back pain) to 5 (worst back pain) in 10 sections (pain intensity, personal care, lifting, walking, sitting, standing, sleeping, sex life, social life, and traveling). ODI Index is calculate.
Narcotic Use Questionnaire	24 months	Self-reported questionnaire to assess narcotic intake. Four questions to record narcotic drug usage (yes or no), frequency and length.
Global Health Scale (GHS)	24 months	Self-reported questionnaire to assess an individual's physical, mental, and social health. Standardized response scores ranges vary from1 to 5 (e.g., 1= None to 5=Very severe) or reversed (5=None to 1=Very severe) to ensure that higher scores for responses always indicate better health.
Visual Analog Scale (VAS) - back and leg pain	24 months	Subjective self-reported scale (1-10) to measure acute and chronic pain. (0= no pain; 10= worst pain possible).
Patient Health Questionnaire-4 (PHQ-4)	24 months	Self-reported brief questionnaire to screen for anxiety and depression. Four questions scoring 0 (not at all) to 3 (nearly every day).
Work Status Questionnaire	24 months	Self-reported short questionnaire to assess work status at present. Simple 3 questions to record ability to work and to attend to work.
PROMIS-CAT	24 months	Patient-Reported Outcomes Measurement Information System to evaluate and monitor physical, mental, and social health. Standardized response scores ranges vary from1 to 5 (e.g., 1= None to 5=Very severe) or reversed (5=None to 1=Very severe) to ensure that higher scores for responses always indicate better health.
Change in number of red blood cells following treatment	24 months	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	24 months	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	24 months	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 Aspartate Aminotransferase (AST)	24 months	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 Serum C-Reactive Protein (CRP)	24 months	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)	24 months	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)	24 months	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	24 months	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	24 months	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	24 months	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	24 months	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 Glucose	24 months	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	24 months	Serological test - basic metabolic panel. The normal range for carbon dioxide is 23 to 29 mEq/L (milliequivalent units per liter of blood).
