What the trial is, and whether it could suit you
The goal of this investigational study is to evaluate the safety and clinical performance of Tropocells Autologous Platelet-rich Fibrin (PRF) for wound care for both males and females, ages 18-80 years old, with Grade 1 and 2, mild to moderate, neuroischemic diabetic chronic foot ulcers in subjects with Type 1 and Type 2 Diabetes Mellitus. The main question\[s\] it aims to answer \[is/are\]:
Measure 1: Wound Closure with Tropocells Autologous PRF System for DFU Measure 2: Safety of Tropocells Autologous PRF System for DFU Researchers will enroll to acquire approximately 30 evaluable subjects with no comparison group.
Run-In Phase (2 weeks): participants with chronic diabetic foot wounds will undergo a 2-week run in phase presenting to the clinic for weekly visits, for standard of care.
Active Treatment Phase (12 weeks): participants that do not show a reduction of at least 20% may be
