Clinical Trial Summary
Investigate the potential of tissue grafting that includes human mesenchymal stem cells in
the repair and potential stabilization of the degenerative Lumbar disk and facet joint
denovo and at the time of surgical reconstruction. Our hypothesis proposes that
stabilization will help restore normal structure and function in the degenerative lumbar
spine may decrease chronic low back pain associated with the biomechanical demise of the
degenerative disk or facet and may improve the natural history of adjacent segment disease
found after spinal surgery.
Description:
This study is a prospective cohort clinical study, of tissue grafts containing nucleated
adult derived autologous or allograft mesenchymal stem cells delivered via intra-discal or
intra-facet injections in subjects with chronic low back pain due to either lumbar
degenerative disk disease or degenerative facet disease at one to five lumbar levels from L1
to S1 in patients who have been unresponsive to conservative therapy. A second cohort
evaluating the development of adjacent segment disease in the lumbar disk and facet joints
after nucleated adult mesenchymal stem cells are delivered via intra-discal or intra-facet
injections during surgical treatment of adjacent levels for degenerative pathology in the
spine. Traditionally, treatment of degenerative spinal conditions has focused on the
reconstruction of damaged tissues within the motion segments of the spine. However, biologic
treatment of degenerated spinal components should address the etiology of the disease
process as opposed to reacting to symptomatology. Strategies to induce a reparative response
within the disk and facet joint focus on rebuilding the chondrocyte population and inducing
their production of healthy biomechanical extracellular matrix.. Current models to induce a
reparative response include; injection of proteins to stimulate proteoglycan production or
inhibit the inflammatory response; transfer of genetic material to cells within the dammed
structures; engineering of newly formed tissues ex-vivo for implantation; and finally
repopulation of the damaged tissues with cells that can repair the injured structures.
Subjects who meet strict inclusion/exclusion criteria will be enrolled in the study for
injection of allograft or autologous tissue grafting that includes mesenchymal stem cells
into their degenerative lumbar spine and followed for a minimum of 2 years for efficacy and
adverse events. This is a prospective clinical study cohort comparing allograft to autograft
cellular tissue graft injections in subjects with chronic low back pain due to either lumbar
degenerative disk disease or degenerative facet disease at one to five lumbar levels from L1
to S1 in patients who have been unresponsive to conservative therapy for at least 3
months.Pre-treatment imaging criteria including Pfirmann Lumbar disk Scores and/or Fujiwara
Facet Joint Scores will be noted during the screening visits. After the screening and
treatment visits, each subject will be evaluated at 2 weeks, 6 weeks, and again at 3, 6, 12,
24 months after injection.
MRI scanning will be performed at the 6 month post-procedure visit and Pfirmann or Fujiwara
Scores will be calculated along with notation of adjacent level disease, epidural pathology
(i.e. new disk herniations), or new imaging findings. Patients will be given informed
consent to participate the individual treatment they are to receive. This informed consent
will follow US FDA guidelines detailed in ICH E6 Section 4.8 of the US Department of Health
and Human Services Center for Drug/Biologics Evaluation and Research. At completion of
enrollment patients will have surgical sterile preparation and draping. All JCAHO Surgical
Care Improvement Project protocols including pre-operative antibiotics will be adhered to.
The disk or facet joint of interest will be verified by fluoroscopy and will be sterilely
cannulated with an 21 to 11G needle based on anatomic requirements. At this point injection
of FDA approved allograft or autograft mesenchymal stem cells within a demineralized bone
matrix or hyalouronic acid carrier respectively will be injected in to the facet joint or
disk space. Needle will be removed and sterile dressing will be placed. Patients will be
placed in a post operative brace for stabilization of the index level to aid in healing.
Patients will be discharged home once standard outpatient discharge criteria are met per
JCAHO guidelines. Follow up periods will be adhered to as noted above. Patient safety will
be strictly monitored in the pre-procedure, peri-procedure, and post-procedure periods for a
minimum of 2 years. All patients will be assigned to a follow up surgeon at specific follow
up periods and no patients will be denied any care during that period. Physical examination
will be documented at each visit. Additionally, scheduled imaging studies will be performed
throughout the study period to follow safety. Patients will be followed by their surgical
investigator, who will be responsible for diagnosis and management of any complications or
adverse events. Development of additional non-spinal disease processes will also be
documented to follow any trends that occur including any new related or un-related diseases.
Safety of patient confidentiality is an additional study related risk, which will be
optimized to the fullest by adhering to the US Health Insurance Portability and
Accountability Act of 1996 (HIPAA). Any Serious Adverse Events (SAE) as defined by the US
FDA will be reported immediately to the IRB for evaluation. A SAE is classified as an
adverse event that results in hospital admission or hospital stay, or alteration of the body
in a permanent way. Surgeon investigators will provide pre-operative, peri-operative, and
post-operative care for all subjects.
Pre-operative, peri-operative, and post operative data will be collected. Patients will be
followed for a minimum of 2 years within the US or Canada with a study investigator for data
collection at 2 weeks (±1 wk), 6 weeks (±2 wks), and 3 months (±2 wks), 6 months (±1 mo), 9
months (± 1.5 months), 12 months (±2 mos), and 24 months (±2 mos). Data may be entered as at
additional time points as needed. Re-admission, re-injection, and additional
hospital/outpatient events will be collected including possible additional surgical
procedures. Data will be managed by the investigator or their designee in a computerized
database accessible only by research staff with original information kept with the patient
medical record in the hospital or follow up sub-investigator office. Comparative statistical
analysis will be performed prior to any publication to validate data and conclusions. Study
staff and the Principle Investigator (PI) agree to conduct the study(ies) in accordance with
the relevant, current protocol(s) and will only make changes in a protocol after notifying
the sponsor, except when necessary to protect the safety, rights, or welfare of subjects.
The PI agrees to personally conduct or supervise the described investigation(s). The PI
agrees to inform any patients, or any persons used as controls, when drugs or devices are
being used for investigational purposes and the PI will ensure that the requirements
relating to obtaining informed consent in US 21 CFR Part 50 and institutional review board
(IRB) review and approval in US 21 CFR Part 56 are met. The PI agrees to report to the
sponsor adverse experiences that occur in the course of the investigation(s) in accordance
with US 21 CFR 312.64. The PI understands the potential risks and side effects of all
treatments, investigational and standard of care. The PI agrees to ensure that all
associates, colleagues, and employees assisting in the conduct of the study(ies) are
informed about their obligations in meeting the above commitments. The PI agrees to maintain
adequate and accurate records in accordance with US 21 CFR 312.62 and to make those records
available for inspection in accordance with US 21 CFR 312.68 if the study is applied and
accepted for US FDA review. The PI will ensure that the IRB complies with the requirements
of US 21 CFR Part 56 will be responsible for the initial and continuing review and approval
of the clinical investigation. The PI also agrees to promptly report to the IRB all changes
in the research activity and all unanticipated problems involving risks to human subjects or
others. Additionally, the PI will not make any changes in the research without IRB approval,
except where necessary to eliminate apparent immediate hazards to human subjects. The PI
agrees to comply with all other requirements regarding the obligations of clinical
investigators and all other pertinent requirements in US 21 CFR Part 312. Medical Ethics are
of primary importance during a study of that exposes humans to a new treatment. The
scientific merit of the study protocol, potential social value of the research, skill and
experience of the investigators, and potential financial exploitation of the study subjects
are all of paramount concern. Thus, in addition to abiding by the US FDA Quality Assurance
Policy (Form 1572), the World Health Organization's "Declaration of Helsinki" involving the
Ethical Principles for Medical Research Involving Human Subjects will be abided by
throughout the trial. Finally, as this study involves subjects that reside within the United
States, the investigators in this trial will also abide by Title 45 Part 46 of the Code of
[US] Federal Regulations, Protection of Human Subjects (45 CFR 46).
