简要总结
The purpose of this study is to determine the effectiveness of Autologous Bone Marrow-Derived Mesenchymal Stem Cells (MSCs) in the treatment of non-healing wounds.
详细描述
Sixty-six (66) subjects are planned to be enrolled into the trial. each subject's duration of participation will be 24 weeks on therapy with a 4 week post-treatment visit. A run-in phase of 2 weeks will be required prior to randomization/enrollment.
All subjects will receive appropriate and standard care for chronic wounds, including dressings, bandages, and off-loading, if required. All subjects will receive either saline, fibrin or MSCs in fibrin using an identical double-barreled syringe to keep the blind. Therefore, subjects will then be randomized to one of three groups:
- conventional standard therapy and control saline spray
- conventional standard therapy and fibrin spray
- conventional standard therapy and MSCs (autologous bone marrow-derived mesenchymal stem cell)in fibrin spray
Screening Visit:
All inclusion and exclusion information will be reviewed to make sure that the subject is eligible for entry into the study. The following procedures will be performed during this two week period:
