A Cohort Trial Comparing AutoloGel Therapy to Usual and Customary Care in Venous Leg Ulcers

Inclusion Criteria: 1. Medicare/Medicaid eligible 2. ≥18 years of age 3. Proven venous disease 4. The largest non-healing wound, if multiple wounds are present, or the single wound to be treated (Index Ulcer) that is located between and including the knee and the ankle 5. For subjects with potentially multiple eligible VLUs, the largest ulcer will be selected. There must be at least 4 cm between the Index Ulcer and other ulcers; if all ulcers are closer than 4 cm, the subject should not be enrolled (screen failure) 6. Debrided ulcer size between 2 cm2 and 200 cm2 7. Demonstrated adequate compression regimen 8. Duration ≥ 1 month at first visit 9. Subject must be willing to comply with the Protocol, which will be assessed by enrolling clinician. Exclusion Criteria: 1. Subjects known to be sensitive to AutoloGel components (calcium chloride, thrombin, ascorbic acid) and/or materials of bovine origin 2. Presence of another wound that is concurrently treated and might interfere with treatment of index wound by AutoloGel 3. Ulcer not of VLU pathophysiology (e.g., pure diabetic, vasculitic, radiation, rheumatoid, collagen vascular disease, pressure, or arterial etiology) 4. Any malignancy other than non-melanoma skin cancer 5. Subjects who are cognitively impaired and do not have a healthcare proxy 6. Serum albumin of less than 2.5 g/dL 7. Plasma Platelet count of less than 100 x 109/L 8. Hemoglobin of less than 10.5 g/dL 9. Subject has inadequate venous access for repeated blood draw required for AutoloGel Administration
