Using TropoCells(R) Autologous Platelet-Rich Fibrin (PRF) to Treat Chronic Non-Healing Wounds

Chronic wounds are wounds that fail to progress through a normal healing process in a timely fashion. Typically the wounds remain in a pro-inflammatory state. The activation of platelets reacting to tissue damage initiates most healing sequences. The use of activated platelets in the form or platelet-rich plasma (PRP) and/or platelet-rich fibrin (PRF) applied to a clean wound base has been associated with improved wound healing outcomes for bony and soft tissues, especially when associated with standard of care (SOC), including supporting underlying medical conditions, improved perfusion and oxygenation, edema control, removing recurrent insults for trauma, treating infection, and preventing ongoing inflammatory triggers. Activated platelets in the form of Tropocells(R) autologous platelet-rich fibrin (PRF) made from "blood drawn from peripheral veins, and centrifuged into a gel, topically applied to exuding cutaneous wounds such as leg ulcers, pressure ulcers and diabetic ulcers, and mechanically or surgically-debrided wounds." Sixteen (16) Subjects will be enrolled to evaluate the efficacy and safety when used to treat chronic noninfected, nonhealing, mild to moderately ischemic wounds.
