Clinical Trial Summary

The investigator's goal is to determine the effectiveness of stromal vascular fraction (SVF) cell injection to treat small rotator cuff tears without surgery.

Description:

Small rotator cuff tendon tears are a hard task in shoulder care. They are often not operated on because research has not shown any increased benefit of surgery over physical therapy. The most common way to treat these tears is through physical therapy or steroid injections. However, the relief doesn't last very long. Recent studies have shown a lot of tears get worse over time. This happens because the physical therapy options can treat the pain and symptoms, but do not heal the actual tear. Another non-surgical option for treating small tears is through adipose-derived stem cells. Adipose-derived stem cells are cells that are found in the fat in our bodies. The cells have shown promise in fixing tissues and may provide help to treat small rotator cuff tears. The investigators are studying a part of these fat cells known as the stromal vascular fraction (SVF). The SVF contains a number of cells that are able to become a variety of different cells. This is important because they may be able to turn into cells that may help heal the damaged rotator cuff tendons. These cells have been shown to improve results after rotator cuff surgery, but no research has used these cells to help small tears without surgery. The use of SVF is investigational. "Investigational" means that the drug being tested has not been approved for routine clinical use or for the use described in this study by the United States Food and Drug Administration (FDA). The FDA is allowing the use of this drug for research. The investigators goal is to determine the effectiveness of SVF cell injection to treat small rotator cuff tears without surgery.

Intervention

Drug:
• Tisseel Injectable Product
Fibrin glue will provide an inert, biocompatible, viscous substance able to remain within the Rotator Cuff (RC) defect rather than injecting SVF cells in saline.

Biological:
• Stromal Vascular Fraction Cells
Stromal Vascular Fraction cells are autologously harvested, processed and reinjected into the affected shoulder.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Primary Efficacy - MRI-measured healing rate in the rotator cuff tear	Healing rates between the treatment with stromal vascular fraction (SVF) cells and exercise program (EP) group will be compared to the sham and EP group.	24 months
Primary	Primary Safety - Incidence/Rates of adverse events (AEs) involving the affected joint	Both study-related AE assessments and the clinical record will be interrogated to determine if the subjects had any adverse events involving the affected joint. Incidence and rates of AEs between the treatment with stromal vascular fraction (SVF) cells and exercise program (EP) group will be compared to the sham and EP group.	24 months
Secondary	Patient-reported measures Western Ontario Rotator Cuff (WORC) Index	WORC score - Compare clinical outcomes between treatment with stromal vascular fraction (SVF) cells and EP and sham injection and EP. The investigators expect the SVF-treated patients to improve by over 12% on the WORC at the final 2-yr follow-up.	24 months
Secondary	Patient-reported measures Patient Reported Outcomes Measurement Information System (PROMIS)	PROMIS score - Compare clinical outcomes between treatment with stromal vascular fraction (SVF) cells and EP and sham injection and EP.expect the SVF-treated patients to improve by 10 points on the PROMIS at the final 2-yr follow-up.	24 months
Secondary	Patient-reported measures Visual Analog Scale (VAS)	Pain VAS score - Compare clinical outcomes between treatment with stromal vascular fraction (SVF) cells and EP and sham injection and EP. expect the SVF-treated patients to improve by over 12% on the WORC, by 10 points on the PROMIS, and by 20% on the pain VAS by the final 2-yr follow-up. expect the SVF-treated patients to improve by 20% on the pain VAS at the final 2-yr follow-up.	24 months
