A Study to Evaluate the Efficacy of a Purified Native Type 1 Collagen Extracellular Matrix With Polyhexamethylene Biguanide Antimicrobial (PCMP) and Standard of Care Versus Standard of Care Alone in the Management of Nonhealing Diabetic Foot Ulcers

Korábbi kezelés

• The potential subject is receiving immunosuppressants or cytotoxic chemotherapy or is taking medications that the PI believes will interfere with wound healing.
• The potential subject with a previous partial amputation on the affected foot that results in a deformity that impedes proper offloading of the target ulcer.
• Participation in a clinical trial involving treatment with an investigational product within the previous 30 days.
• The potential subject was treated with hyperbaric oxygen therapy (HBOT) or a Cellular, Acellular, Matrix-like Product (CAMP) in the 30 days prior to the initial screening visit.

Más betegség

• The target ulcer is infected or there is cellulitis in the surrounding skin.
• The target ulcer exposes tendon or bone.
• There is an infection in the target ulcer or in a remote location that requires systemic antibiotic therapy.
• The potential subject has applied topical steroids to the ulcer surface within one month of initial screening.
• The potential subject has an acute Charcot foot, or an inactive Charcot foot, which impedes proper offloading of the target ulcer.
• The potential subject has end stage renal disease requiring dialysis.
• A potential subject who, in the opinion of the investigator, has a medical or psychological condition that may interfere with study assessments.

Laborértékek

• The potential subject has a controlled glycated hemoglobin (HbA1c) within 3 months of the initial screening visit.
