Clinical Trial Summary

Patients scheduled for major extremity lower amputation to receive bone marrow cells (cBMA) injected IM in the leg proximal to the amputation in the index limb to prevent ischemic wound complications after surgery.

Description:

Patients scheduled for amputation will receive bone marrow cells concentrated via the MarrowStim device (cBMA) injected IM at 25 sites in the leg proximal to the amputation in the index limb to prevent ischemic wound complications after surgery. cBMA will be injected into the anterior tibialis muscle below the point of amputation in an area approximately 3cm^2 x 2cm^2 for analytical purposes. Patients will be scheduled for amputation at Days 7, 14, or 21 post injection. Safety will be evaluated by review of treatment related adverse events (AE) during the 52-week follow-up period. The investigator will compare rates of wound complications and amputation revisions to historical controls at the institution to assess trends in therapeutic efficacy.

Patients will undergo amputation and injection sites will be harvested at that time. Immunohistochemical staining (IHC) will determine capillary density and local host immune responses. Angiogenic and inflammatory cytokines will be quantified using a multiplex array system and quantitative polymerase chain reaction (PCR).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of participants with treatment-related adverse events occurring during the enrollment period as assessed by the Investigator using the CTCAE 4.0 scale.	Safety will be evaluated by review of treatment related AEs during the 12-month follow-up period. The study will be terminated in the event of a Grade 4-5 unexpected event based on the Common Terminology Criteria for Adverse Events (CTCAE), version 4.0. Treatment-related AEs will be categorized overlapping systems and severities. Three categories of systems are cardiovascular, respiratory, or infectious. Two categories of severity will be serious adverse (SAE) and major adverse cardiac events (MACE). Binomial confidence Intervals at the 95% confidence level and p-values for these 3 groups will be calculated. Since previous trials have not reported AEs with cBMA treatment, confidence intervals will be generated by the method of the Wilson Score Interval.	Primary follow up in a 12 month period
Secondary	Time period of retention of allogeneic MSCs in harvested human skeletal muscle tissue post-MSC implantation as measured by immunohistochemical staining and number of MSCs per section of skeletal muscle at each time point .	Sections of skeletal muscle collected from each injection site will be stained with specific antibodies for MSC specific markers and the number of MSCs will be counted in each field under a microscope.	Primary follow up in a 12 month period
Secondary	The role of MSCs injected in human skeletal muscle at the time of below knee amputation as evidenced by recruitment of proangiogenic hematopoietic cells into sites of ischemia.	Continuous confidence intervals at the 95% level will be constructed to explore differences among the time-tiered administration of MSC for the quantity of capillary density in muscle fibers, examine changes in morphology, and the recruitment of HIF-1a/SDF-1/CXCR4 to ischemic muscle.	Primary follow up in a 12 month period
