๐ฌIn plain words
What the trial is, and whether it could suit you
This is a double-blind, controlled, randomized study with blinded assessments using a single dose. Subjects that have a current diagnosis of chronic lumbar disc disease and meet eligibility criteria will be enrolled. Chronic lumbar disc disease is defined as back and/or radicular pain with degeneration of the disc confirmed by patient history, physical examination, and radiographic measures such as computed tomography (CT), magnetic resonance imaging (MRI), plain film, myelography, discography, or other acceptable means.

๐ Eligibility rules (as published)
Subject Inclusion Criteria:
A subject is eligible for inclusion if all the following criteria are met:
1. A high index of suspicion for discogenic pain, (i.e., painful degenerative disc(s) with or without protrusions less than or equal to 5 mm)
1. Chronic Lower Back Pain for at least 6 months
2. Pain commonly provoked by prolonged sitting, forward bending, lifting, twisting, coughing, sneezing, or Valsalva maneuvers
3. Failure of at least 6 months of conservative back pain care (can include any or all of the following: rest, anti-inflammatory medication, analgesics, narcotics, epidural injections or selective nerve root injections at the target level, facet joint injections, muscle relaxers, massage, acupuncture, chiropractic care)
4. Failure of supervised therapy (such as physical therapy)
5. Screening of โฅ 40 mm and โค 80 mm on low back pain visual analog scales (VAS) (average pain in the last week)
6. Screening Oswestry Disability Index (ODI) score โฅ 30 and \< 90 on a 100-point scale
7. No localized and significant pain below beltline (i.e., potential sacroiliac joint pain) without lumbar pain component
8. Thigh or Leg pain, if present, is non prevailing and of nonradicular origin, i.e., not due to stimulation of nerve roots or dorsal root ganglion of a spinal nerve by compressive forces
9. Diagnostic medial branch block or facet joint injection (bilateral unless the symptoms are purely unilateral in nature) in the last 12 months prior to the informed consent date indicates no prevailing facet joint involvement
2. Has degenerative disc disease (DDD) as defined by the following:
1. Changes from normal disc morphology of the affected disc as defined by radiographic evaluation
2. Modified Pfirrmann score of 2 to 7 on MRI, may contain a contained protrusion and/or annular tear on MRI
3. Modified Pfirrmann score of 1 must contain a contained protrusion and/or annular tear on MRI
4. Modic Grade I or II changes or no change on MRI
5. Maintained intervertebral disc heights of at least 50% on MRI.
6. Discography, if not performed within the last 6 months prior to informed consent date, has to be performed if more than one degenerative disc is identified by MRI, and the symptomatic disc cannot be otherwise reasonably determined
7. If more than one degenerative disc is identified by MRI, no disc shall demonstrate greater degenerative change than the symptomatic disc or contain a protrusion greater than 5mm
3. Aged โฅ18 years of age at the time of consent
4. Willing and able to provide written informed consent
5. No evidence of contraindications to the procedure such as pregnancy, active infection, bleeding disorder, or metastatic cancer
Subject Exclusion Criteria:
A subject is not eligible to participate if any of the following criteria are met:
1. Spinal Deformity (Scoliosis greater than or equal to 20 degrees, spondylolysis, clinically or radiographically significant retrolisthesis or spondylolisthesis) detected on MRI or plain film radiographic assessment
2. Disc extrusions, sequestered fragments, facet cysts, or greater than moderate spinal stenosis on MRI.
3. Presence of a Grade V annular fissure observed within the index disc level during discography in a subject for whom provocation discography has been performed
4. Intervertebral disc with radiographic evidence of Modified Pfirrmann Grade 8 or greater
5. Any bleeding disorder, intrinsic or extrinsic
6. Required anticoagulation (with either antiplatelet agents or antithrombotics) that cannot be interrupted for harvest and injection procedures
7. Platelet count less than or equal to 100,000
8. International Normalized Ratio (INR) greater than or equal to 1.5
9. Extreme obesity, as defined by NIH Clinical Guidelines Body Mass Index (BMI greater than or equal to 40)
10. Clinically relevant instability on flexion-extension as determined by the investigator by overlaying films (flexion \& extension films)
11. Has undergone any previous lumbosacral spine surgery (e.g. discectomy, laminectomy, foraminotomy, fusion, intradiscal electrothermal therapy, intradiscal radiofrequency thermocoagulation.), ablation of lumbar basiverterbral nerve or therapeutic percutaneous disc intervention
12. Have any acute or chronic lumbosacral spine fracture
13. Have a history of lumbosacral epidural steroid injections within 1 month prior to informed consent date.
14. Planned/expected use of systemic nonsteroidal anti-inflammatory drugs (NSAIDs) within 72 hours prior to study treatment.
15. Have a known history of hypersensitivity or anaphylactic reaction to dimethyl sulfoxide (DMSO)
16. Active significant non lumbosacral spinal orthopedic pain generators including, not limited to arthritic hip and/or knee, cervical disc disease
17. More widespread and ill-defined myofascial pain
18. Have had treatment with any cellular or biological investigational therapy or device within 6 months of informed consent date and/or plans to participate in any other autologous or allogeneic stem cell/progenitor cell therapy trial during the 2 year follow-up period
19. Have been a recipient of any lumbosacral intervertebral disc injection for therapeutic purposes
20. Are transient or has been treated in the last 6 months before enrollment for alcohol and/or drug abuse in an inpatient substance abuse program
