- Brief Summary
This study will examine differences in the process of wound-healing in patients treated with platelet rich plasma (a concentration of proteins derived from a patients own blood) applied to the wound as a gel; injected into the wound or surrounding tissue; or both; compared to patients treated with usual medical treatment . This study seeks to enroll patients who are 18 or older with a non-healing skin wound that is at least 30 days old. Only patients with Diabetic Foot Ulcers, Venous Ulcers, or Pressure Ulcers will be included in the study.
- Detailed Description
The proposed investigation is designed to solicit a large number of patients (N=1,500) with non-healing wounds (Diabetic Foot Ulcers, Venous Ulcers, or Pressure Ulcers) that have not responded to standard wound care in the previous 30 days or more. A prospective, interventional, single-blinded, controlled, registry trial will be used. Data will be analyzed to compare patients who received PRP therapy (PRP gel application, PRP injection, or both) and standard wound care (usual customary care) with patients who received standard wound care (usual customary care), only. Wound size, rate of healing, quality of life, and recurrence of wound will be measured during the 16-week period at usual office visits.
Hypotheses to be tested:
1. Treatment of a chronic wound with standard of care and autologous platelet rich plasma (PRP) will increase the velocity of healing (rate of wound closure) over a twenty week period as compared to patients receiving standard wound care only (Control Group), which results in the patient's ability to return to previous function and resumption of normal activities.
2. Treatment of a chronic wound with standard of care and autologous platelet rich plasma (PRP) will result in complete wound healing within twenty weeks, whereas complete wound healing will not be observed within twenty weeks in patients receiving standard wound care only (Control Group).

Group Intervention Description Autologous PRP Gel Standard Wound Care The method of application for PRP treatment will be decided by the clinician in accordance with the appearance of the wound bed. The application of topical PRP gel may be used in chronic wounds possessing an open, moist wound bed according to following treatment schedule: Baseline/Week 0, Week 1, Week 2, Week 3, Week 7, and Week 11. The Arteriocyte Magellan® System (510(k) cleared) will be used to prepare the autologous PRP gel. For data analysis, the data from these patients will be classified as PRP Treatment Group (Topical application) data. Autologous PRP Injections Standard Wound Care The method of application for PRP treatment will be decided by the clinician in accordance with the appearance of the wound bed. Autologous PRP Injections may be used where chronic wounds possess a raised, hyperproliferative wound margin and/or plaque, according to following treatment schedule: Baseline/Week 0, Week 1, Week 2, Week 3, Week 7, and Week 11. The Arteriocyte Magellan® System (510(k) cleared) will be used to prepare Autologous PRP for injections. For data analysis, the data from these patients will be classified as PRP Treatment Group (Direct Injection) data.
