You are invited to take part in this research study because you have diabetes, are between the ages of eighteen (18) and eighty-nine (89) years old and have a diabetic foot ulcer (wound) for thirty (30) days or more. Your wound care provider has determined that you need treatment for this wound. This research is studying a powder wound dressing called Altrazeal® Transforming Powder (Altrazeal®) for treatment of diabetic foot ulcers. Altrazeal® is a powder that is sprinkled directly onto your foot ulcer, after your wound has been cleaned and is ready for a dressing. Altrazeal® is made from a substance (polymer) used to make soft contact lenses. The powder covers and protects the wound. It is designed to stay in place for up to 30 days. Altrazeal® is a Class-I medical device manufactured in the United States (U.S.) by a company that is registered with the United States Food and Drug Administration (FDA). It is currently being used at a number of U.S. and international health care facilities. Altrazeal® has been used on many types of wounds, including diabetic foot ulcers.
