Phase 2 |
Detailed Description
This study is a prospective, double blinded, randomized, cross over phase II study evaluating efficacy and safety of intra-articularly injected BM-MSCs in the treatment of painful facet joint arthropathy. Patients with mild to severe facet OA will be considered for this study. A total of 40 patients with diagnosis evidence of chronic low back pain associated with FJOA and positive outcome of a MBB will be recruited.After confirming eligibility, patients will be randomized to Arm A: Treatment or Arm B: DMSO. After 12 months, patients randomized to Arm B: DMSO will be unblinded and cross-over to Arm A: treatment then be followed for 12 months.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Active Comparator: Arm A Treatment Participants in Arm A will be scheduled for a single set of intra-articular injections of allogeneic, culture-expanded BM-MSCs at the dose 10 x106 in 1 ml per facet joint, for a total of 2 joints to be injected. BM-MSC injections will be performed using fluoroscopic guidance. |
Drug: BM-MSC injection
BM-MSCs at the dose 10 x 106 in 1 ml per facet joint for a total of 2 joints
|
| Placebo Comparator: Arm B: DMSO Crossover Participants in Arm B will receive a DMSO injection. Following the BM-MSC or DMSO injection, each subject will be followed for study endpoints using a predetermined protocol. A final visit for evaluation and imaging will be conducted at the end of the study. |
Drug: DSMO Injection
After 12 months, patients randomized to Arm B: DMSO will be unblinded and re-assigned to Arm A: treatment then be followed for 12 months.

Outcome Measures
Primary Outcome Measures
- Clinical assessment of nature, incidence, and severity of adverse events (AEs) [24 months]
Clinical examination face-to-face during follow-up visits
- Self-reported assessment of nature, incidence, and severity of AEs [24 months]
Spontaneous subject reports
- Study personnel assessment of nature, incidence, and severity of AEs [24 months]
Subject interview by study personnel
- 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.
- 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.
Secondary Outcome Measures
- Changes from baseline evaluated by MRI [24 months]
Facet anatomical structures with focus on effusion, bone marrow lesions and peri-articular edema, osteophytes and degree of facet synovitis will be assessed
Eligibility Criteria
Criteria
Inclusion Criteria:
-
Persons of childbearing potential must be non-nursing and have a negative serum pregnancy test to be included in the trial and will agree to use adequate contraception (hormonal or barrier method or abstinence) from the time of screening to a period of up to 18 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 outcomes. Any SAEs associated with pregnancy will be recorded. The requirement for radiation (X-ray) will be removed.

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;
-
