Adipose Stem Cells for Traumatic Spinal Cord Injury

Overview

  • Study type

    Interventional
  • Study phase

    I
  • Study IDs

  • Describes the nature of a clinical study. Types include:

    • Observational study — observes people and measures outcomes without affecting results.
    • Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
    • Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.
  • During the early phases (phases 1 and 2), researchers assess safety, side effects, optimal dosages and risks/benefits. In the later phase (phase 3), researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid. There are also less common very early (phase 0) and later (phase 4) phases. Phase 0 trials are small trials that help researchers decide if a new agent should be tested in a phase 1 trial. Phase 4 trials look at long-term safety and effectiveness, after a new treatment has been approved and is on the market.

About this study

The purpose of this study is to determine if mesenchymal stem cells (MSC) derived from the fat tissue can be safely administered into the cerebrospinal fluid (CSF) of patients with spinal cord injury. Adipose-derived mesenchymal stem cells (AD-MSCs) have been used in previous research studies at the Mayo Clinic. All subjects enrolled in this study will receive AD-MSC treatment, which is still experimental and is not approved by the U.S. Food and Drug Administration (FDA) for large scale use. However, the FDA has allowed the use of this agent in this research study.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.

Inclusion Criteria:

  1. Male or female aged 18 years and older
    1. Females of childbearing potential must have a negative pregnancy test prior to receiving the study drug and will agree to use adequate contraception (hormonal/barrier method or abstinence) from the time of screening to a period of 1 year following completion of the drug treatment cycle. Females of childbearing potential are defined as premenopausal and not surgically sterilized, or post-menopausal for fewer than 2 years. 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 kit.
    2. Females 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 SAEs associated with pregnancy will be recorded.
  2. AIS grade A or B of SCI
  3. SCI must be traumatic, blunt/non-penetrating in nature and not degenerative
  4. SCI must be within two weeks and up to 1 year after the event
  5. Full understanding of the requirements of the study and willingness to comply with the treatment plan, including fat harvesting, laboratory tests, diagnostic imaging, complete physical and neurologic examination and follow-up visits and assessments
  6. Once the nature of the study is fully explained and prior to any study-related procedure is initiated the subject is willing to provide written, informed consent and complete HIPAA documentation

Exclusion Criteria:

  1. Pregnant or nursing, or planning on becoming pregnant during the study period
  2. AIS grade of SCI other than A or B
  3. History of intra-spinal infection
  4. History of superficial infection in the index spinal level within 6 months of study
  5. Evidence of current superficial infection affecting the index spinal level at the time of enrollment
  6. On chronic, immunosuppressive transplant therapy or having a chronic, immunosuppressive state, including use of systemic steroids/corticosteroids
  7. Taking anti-rheumatic disease medication (including methotrexate or other antimetabolites) within 3 months prior to study enrollment
  8. Ongoing infectious disease, including but not limited to tuberculosis, HIV, hepatitis, and syphilis
  9. Fever, defined as temperature above 100.4 F/38.0 Celsius, or mental confusion at baseline
  10. Significant improvement between the time of adipose tissue harvest and the time of injection, defined as improvement from AIS grade A or B to AIS grade C or greater.
  11. Clinically significant cardiovascular (e.g. history of myocardial infarction, congestive heart failure or uncontrolled hypertension > 90 mmHg diastolic and/or 180 mmHg systolic), neurological (e.g. stroke, TIA) renal, hepatic or endocrine disease (e.g. diabetes, osteoporosis).
  12. History of malignancy including melanoma with the exception of localized skin cancers (with no evidence of metastasis, significant invasion, or re-occurrence within three years of baseline). Any other malignancy will not be allowed.
  13. History of blood dyscrasia, including but not limited to anemia, thrombocytopenia, and monoclonal gammopathy
  14. Participation in a study of an experimental drug or medical device within 3 months of study enrollment
  15. Known allergy to local anesthetics of other components of the study drug
  16. Any contraindication to MRI scan according to MRI guidelines, or unwillingness to undergo MRI procedures
  17. History of or current evidence of alcohol or drug abuse or dependence, recreational use of illicit drug or prescription medications, or use of medical marijuana within 30 days of study entry
  18. Patients with baseline depression, diagnosed by the Beck Depression Inventory Assessment
