Eligibility Criteria
Inclusion
- Male and females aged ≥ 19 years and \< 70 years
- Have low back or hip pain that has lasted ≥ 6 months at the time of screening and do not respond to conservative therapy\* given for ≥ 3 months
- \* Conservative therapy: Rest at an early stage, drug treatment (e.g., anti-inflammatory drugs, analgesics, anesthetics, narcotic analgesics, muscle relaxants), massage, acupuncture, chiropractic treatment, posture correction, home lumbar exercise programs, etc.
- The Oswestry Disability Index (ODI) of 30% or greater and below 90% at screening
- The Visual Analogue Scale (VAS) score for pain in the lumbar spine of ≥ 40 mm and ≤ 90 mm in the last 3 months prior to screening
- The magnetic resonance imaging (MRI) grade 3 to 6 between lumbar vertebra 1 and sacral vertebra 1 according to the modified Pfirrmann classification method at screening
- One pain-causing degenerative lumbar disc identified at screening. However, degenerative lumbar discs causing pain are identified by discography.
- Those who provide written consent to comply with the precautions after they or their representatives voluntarily decide to participate subsequent to listening to a detailed explanation of this clinical study and understanding it completely
Exclusion

- Those with severe osteoporosis
- \* An average T score of -2.5 or less in the lumbar bone density test (DEXA, Dual-Energy X-ray Absorptiometry)
- Those who have undergone procedures (electrocoagulation of the intervertebral disc, etc.) and surgery such as discectomy on the disc to be administered with the investigational product However, in the case of electrocoagulation, enrollment is allowed if the procedure was performed 3 months prior to the administration of the investigational product on the annulus fibrosus, not on the nucleus pulposus.
- Those who took at least 75 mg/day of morphine equivalent dose (MED) during the screening period
- Those who have full-thickness annular tears (modified Dallas diagram scale grade 5) at index level when a contrast medium is administered to annulus fibrosus (AF)
- Those with clinically significant neuralgia (e.g., chronic radiculopathy) or neuropathy
- Those with clinically significant sacroiliac joint pain
- Those who have compressive pathology due to stenosis or disc extrusion confirmed by MRI, and have clinical symptoms of leg pain with VAS of 40 mm or more, or a neurological deficit confirmed in a neurological examination
- Those with intermittent neurogenic claudication due to central vertebral canal stenosis
- Those with lumbar spondylitis or ankylosing spondylitis caused by autoimmune diseases, etc.
- Those with facet joint pain confirmed through a diagnostic medical branch block
- Those who have received an injection of a drug containing steroids into the disc, except for the following drugs, within 3 weeks of the administration of the investigational product (1) Contrast medium (discography or other diagnostic injection) (2) Non-steroidal anti-inflammatory drugs (NSAIDs) (3) Nerve-blocking local anesthetics: e.g., lidocaine, bupivacaine (4) Antibiotics (5) Normal saline (saline)

- Those with a history of allergy to protein products (bovine serum), antibiotics (gentamicin), DMSO, and hyaluronic acid (HA) required for the manufacture of cell-therapeutic drugs
- Those who have a psychiatric history or are being treated, and the investigator determines that it is difficult to proceed with the clinical study
- Those who exceed 30 points on the Beck Depression Inventory (BDI)
