Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  1. Male or female subjects 18 years of age and older

    • Persons of childbearing potential must be non-nursing and have a negative serum pregnancy test prior to receiving the study drug and will agree to use adequate contraception (hormonal or barrier method or abstinence) from the time of screening to a period of 24 months following completion of the drug treatment cycle. Persons of childbearing potential are defined as premenopausal and not surgically sterilized, or post-menopausal for fewer than 2 years. A urine pregnancy test will be performed prior to the administration of the study drug to confirm negative results. If the urine pregnancy test is positive, the study drug will not be administered and the result will be confirmed by a serum pregnancy test. Serum pregnancy tests will be performed at a central clinical laboratory, whereas urine pregnancy tests will be performed by qualified personnel using a kit.
    • Persons becoming pregnant during the study will continue to be monitored for the duration of the study or completion of the pregnancy, whichever is longer. Monitoring will include perinatal and neonatal outcome. Any serious adverse events (SAEs) associated with pregnancy will be recorded. The requirement for radiation (X-ray, MRI) will be removed.
  2. Moderate radiographic degeneration of an Intervertebral Disc (IVD) from L1 to S1, with a disc suspected of causing chronic low back pain. Chronic low back pain is defined as the following:

    • Low back pain for at least 6 months
    • Failed at least 3 months of conservative back pain care. Conservative treatment regimens may include any or all of the following: initial rest, medications e.g., anti-inflammatory, analgesics, narcotics/opioids, muscle relaxants, massage, acupuncture, osteopathic or chiropractic manipulations, activity modification, home-directed lumbar exercise program, and non-invasive pain control treatments or procedures

5. Study Description

Brief Summary
To determine the safety and feasibility of autologous, culture-expanded adipose-derived (AD) mesenchymal stromal cells (MSCs) in subjects with painful degenerative disc disease (DDD).
Detailed Description
This study is a prospective, phase I dose-escalation study evaluating the safety and feasibility of intradiscally injected AD-MSCs in the treatment of painful degenerative disc disease. The investigators propose a blended open enrollment protocol of four cohorts, each comprised of 3 subjects, to allow for interim analysis following the completion of each cohort to review safety data prior to commencing treatment of the next cohort. A total of 12 subjects will be enrolled. Subjects will be screened at outpatient clinic visit appointments and interested qualified subjects will be consented and offered participation in this trial. Once consent has been obtained baseline values will be established and subjects will begin treatment and follow-up for the next 24 months. Baseline data will include physical examination of the axial skeleton and sacroiliac region, neurologic examination, clinical assessment of low back pain and function using validated Patient Reported Outcome Measures (PROMs), radiographs, peripheral blood analysis, and MRI imaging. Abdominal fat will be harvested through a small incision and processed by the Mayo Clinic IMPACT laboratory using current Good Manufacturing Practices (cGMPs) and previously established standard operating procedures (SOPs) to produce clinical grade, autologous, culture-expanded AD-MSCs for subsequent intradiscal injection. All injections will be performed using fluoroscopic guidance and all patients will be clinically evaluated immediately after procedure and at week 2 and 4 post-treatment to assess for acute adverse events (AEs). Following completion of their respective treatment cycle, each subject will be followed for study endpoints using a predetermined protocol, including clinical evaluation, radiography, MRI, and peripheral blood analysis. A final visit for evaluation and imaging will be conducted at the end of the study.
