Protocol and procedures: All randomized subjects will continue to receive standard of care treatment appropriate for their wound for the duration of their study treatment regardless of their assigned treatment group. Subjects will continue to receive assigned study treatment as long as their wound continues to show improvement, as determined by the investigator. Study treatment will continue until wound closure, or for up to 6 weeks without wound closure. A baseline evaluation will include a medical history assessment, VAS pain score, wound history and evaluation including: wound dimension measurements, overall wound assessment, digital photography, and appropriate sharp debridement, if necessary. Weekly wound assessments will include a wound evaluation, digital photography and VAS pain score. Prospective data will also be collected on specific wound care supplies and interventions provided. These data will be tracked as interventions occur while the wound continues to be treated with the assigned study treatment. Economic data will include type, quantity, duration, associated frequency, and professional time requirements.
