About

Researchers are conducting this study to learn more about the side effects of bone marrow-derived stem cells when injected into the facet joints for the treatment of painful lumbar facet joint arthropathies.

Full description

Phase I prospective study to determine the safety and feasibility of allogeneic, culture-expanded BM-MSCs in subjects with painful facet-mediated low back pain. Target accrual is 10 subjects with diagnosis of painful lumbar facet joint arthropathy. Eligible subjects will receive a single set of intra-articular bilateral injections of allogeneic, culture-expanded BM-MSCs human, allogeneic, culture expanded, bone-marrow-derived mesenchymal stem cells. Subjects will be evaluated at baseline, treatment day 0, post-operative day 1, post-operative days 3-5, week 2, and months 3, 6, 12, 18 and 24 months post-treatment.

Exclusion criteria

Any lumbar facet intra-articular injection including steroids at the index facet level prior to treatment injection in the past 3 months
Subjects that have undergone a procedure affecting the structure/biomechanics of the index facet joint or a spinal fusion adjacent to the symptomatic level.
Have undergone any procedure using biological treatment for any condition such as bone marrow aspirate concentrate, PRP, bone marrow-derived MSCs, adipose-derived MSCs, SVF, micro fragmented fat, embryonic membrane product etc.
Clinically relevant instability on flexion-extension as determined by the primary investigator by overlaying films.
Have an acute fracture of the spine at the time of enrollment in the study or clinically compromised vertebral bodies at the affected level due to current or past trauma.

Epidural steroid injections within 4 weeks prior to treatment injection.
Active malignancy or tumor as a source of symptoms or history of malignancy within the 5 years prior to enrollment in the study, except history of basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or squamous cell carcinoma of the cervix if fully excised and with clear margins.
An elevated average baseline morphine equivalent dose, as determined by the investigator during screening consultation.
