Brief summary: The purpose of this study is to see if the use of Alocyte (cord blood plasma plus mononucleic cells) will be safe, well tolerated, and whether it causes any side effects. The study will also examine if the use of the Investigational Product (IP) is able to reduce local inflammation or alleviate Facetogenic back pain

Detailed description: Ghormley, in 1933, was the first to perform oblique spine radiographs to view the zygapophysial or facet joints and coin the term "facet syndrome" to refer to LBP with "sciatica" originating from the facet joints. The facet joint may be affected by systemic disease, such as rheumatoid arthritis and ankylosing spondylitis, or be site of micro traumatic fractures, such as osteoarthritis, meniscoid entrapment, synovial impingement, joint subluxation, synovial inflammation, loss of cartilage, and mechanical injury. Facetogenic pain is the result of repetitive stress and/or cumulative low-level trauma, leading to inflammation and stretching of the joint capsule.

Current treatment options for this disease are limited to symptomatic treatment, including analgesics, physiotherapy, and minimally invasive or surgical treatment (spinal fusion or non-fusion), but none of the methods addresses the underlying problem. The pathological process of intervertebral disc degeneration cannot be prevented by these therapies.

Alocyte is a cellular, minimally manipulated product derived from umbilical cord blood. Alocyte's manufacturing methodology is designed to enrich human umbilical cord plasma and human umbilical cord blood-derived mononuclear cells (hematopoietic lineage cells such as lymphocytes, monocytes, stem and progenitor cells, as well as mesenchymal stem cells) present in full-term cord blood. The final product is composed of a heterogenous population of cellular products, mainly the exosomes, cytokines, and nucleated cells.

Cytokine expression of Alocyte was fully evaluated. Alocyte showed a robust expression of RANTES, Osteopontin, and Angiostatin where the first two are stem cell repair cytokines and the latter is pro-angiogenic cytokine. Other cytokine showed moderate levels are IL-8, PDGF-BB, TIMP-1, TIMP-2, Angiopoietin-1, Angiogenin, MMP-9, Tie-2, uPAR, BDNF, TGF-ß2, GRO, IGFBP-1, IGFBP-2, IL-8, IL-12-p40, MIF, and NAP-2. Alocyte contained a variety of pro-angiogenic, immune-modulatory, anti-inflammatory, pro-metabolism, and tissue repair growth factors.

Therefore, a regenerative approach for treating Facetogenic pain will be beneficial by promoting changes in the pathogenic mechanism triggered by the cellular therapeutic product Alocyte.

Eligibility criteria: Inclusion Criteria:

* In order to be eligible to participate in this study, all individuals must meet all of the following criteria:

  1. Subjects age \> 18 years at the time of signing the Informed Consent Form.
  2. Male or Female.
  3. Ability of participant to understand and the willingness to sign a written informed consent document.
  4. Facetogenic back pain diagnosed using the following diagnostic criteria Subjects who have chronic low back pain based on clinical evaluation. Pain onset at dorsal extension and release at flexion is often considered suggestive for facet pain, even if non-specific, such as maximal tenderness upon deep palpation of posterior elements.
  5. Patient with up to 5 diseased facet joints
  6. Chronic Facetogenic pain (≥ 6 months) in patients that have failed conservative management
  7. Subjects must be reasonably able to return for multiple follow-up visits.
  8. For Women of Child-Bearing Potential (WOCBP) only, willingness to use FDA-recommended birth control until 6 months post treatment.
  9. Any male subject must agree to use contraceptives and not donate sperm during the study.

Exclusion Criteria:

1. Previous surgical intervention for back pain
2. Previous stem cell injection(s) within the last year
3. Use of anticoagulation or NSAIDs within 5 days of the injection
4. MRI finding of severe high-grade lumbar stenosis
5. Leg pain exceeding back pain
6. Pain worse with flexion maneuvers
7. Fracture of lumbar vertebrae
8. Inability to perform any of the assessments required for endpoint analysis.
9. Clinically significant abnormal screening laboratory or clinical assessment values
10. Use of medications during the early phase of treatment such as chronic narcotic use, systemic corticosteroid administration, local corticosteroid injection at facets anticoagulant therapy and viscosupplementation into facets, any investigational drug used within 3 months prior to screening or during study and surgery in the facets
11. Subjects with serious co-morbidities are excluded.
12. Evidence of inflammatory arthritis (example, rheumatoid arthritis and ankylosing spondylitis) or traumatic fractures, osteoarthritis, meniscoid entrapment, synovial impingement, joint subluxation, synovial inflammation, loss of cartilage, and mechanical injury.
13. Have a clinical history of malignancy within 5 years (i.e., subjects with prior malignancy must be disease free for 5 years), except curatively treated basal cell carcinoma, squamous cell carcinoma, melanoma in situ or cervical carcinoma, if recurrence occurs.
14. Be currently participating (or participated within the previous 6 months) in an investigational therapeutic or device trial.
15. Exhibiting signs of moderate or severe chronic respiratory disease (such as COPD, asthma, or pulmonary fibrosis).
16. Patient with rheumatologic disorders.
17. History of chronic liver disease or patient showing signs of clinical jaundice at the time of screening.

25. Subject has or had an active infection requiring systemic antibiotics within 12 weeks of enrollment in the study
