Tropocells® Autologous Platelet-Rich Fibrin (PRF) is being used to treat chronic, non-healing wounds, of a variety of types. This will help determine the safety and effective use of PRF in the treatment of soft tissue defects.', 'detailedDescription': '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.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '80 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* 1\\.

If the wound is in an ulcer cluster the dominant ulcer will be selected, with at least 2.0 cm2 between the index wound and other wounds.\n\n 6\\. The study wound will be present for at least thirty (30) days and the subject will have undergone standard of care assessment and intervention, according to the wound type being evaluated, where SOC may include, but not be limited to, proper cleansing and debridement, off-loading, compression, bioburden reduction, moisture management, infection control, optimized perfusion, venous ablation, nutrition supplementation, smoking cessation counseling and medical therapy, and access to wound and underlying disease education and training.\n\n 7\\. Neurovascular assessment, conducted according to the assessment typically performed for the wound type will be performed during Screening (Study Visit 1), and repeated at the level normally conducted at the follow-up visits. Perfusion should be adequate to sustain a healing process. Neurological examinations will be performed to document the presence of neuropathy and/or nerve injury.\n\n 8\\. Documented 40% or less wound closure during thirty (30) days of standard of care (SOC).\n\n 9\\. No clinical signs of infection at the wound site or the affected limb. 10.

HbA1C ≤ 12%. 14. Chronic renal failure (CRF) and dialysis patients may be enrolled. 15. PT/aPTT/INR should be within normal limits unless the subject is on coumadin, then maintain range of INR 2 to 3.\n\n 16\\. Prealbumin ≥ 15 mg/dL. 17. Adequate off-loading of the wound site for wheelchair bound, bed bound, and ambulatory subjects.\n\n 18\\. Multi-layered compression dressings for venous related wounds. 19.

Life expectancy is less than twelve (12) months.\n 2. Participation in another clinical trial involving an investigational device or drug within thirty (30) days prior to enrollment.\n 3. Sepsis within two (2) weeks prior to enrollment.\n 4. Soft tissue infection affecting the wound within two (2) weeks prior to enrollment.\n 5. Known osteomyelitis or occult osteomyelitis documented with inflammatory markers ESR ≥ 60 and/or CRP ≥7.9 mg/dL.\n 6. Religious constraints to using blood products, including autologous blood.\n 7. Alcohol or substance abuse (other than tobacco) within 2 months prior.\n 8. Severe lymphedema at Stage 3b or greater (lymphostatic elephantiasis).\n 9. The inability to use compression therapy for venous insufficiency or lymphedema.\n 10. Subjects who are cognitively impaired, unable to understand the informed consent, or have a health care proxy.\n 11. Hemophilia, sickle cell anemia, thrombocytopenia, and leukemia or blood dyscrasia.\n 12. History of problems with coagulation, abnormal thrombocytes (platelets), or receiving heparin, intravenously. However, subjects taking coumadin, aspirin, clopidogrel, or other oral anti-coagulants are not excluded.\n 13. Cytostatic therapy within the past 12 months.\n 14. The subject has inadequate venous access for repeated blood draw.\n 15. Known HBV, HCV, or HIV.\n 16. Blood-borne or communicable disease that would likely prevent full participation in the trial (HIV, AIDS, COVID-19).\n 17. Subjects with known sensitivity to blood components of the PRF Kit (e.g., rubber stopper, vacutainer tubing).\n 18.
