Must have
Subjects must be at least 18 years of age or older

Follow Up 6 and 12 weeks
Awards & highlights


This trial will compare two different treatments for Diabetic Foot Wounds in multiple medical centers to see which one works better.

Who is the study for?
Adults over 18 with type 1 or 2 diabetes and a foot ulcer not probing to bone can join. The ulcer must be on the foot, present for 4-52 weeks, sized between 1.0-20.0 cm² after debridement, and offloaded for at least two weeks if plantar. Good blood flow to the foot is required; severe kidney disease, recent investigational drug use, pregnancy plans within six months, high HbA1c levels (>12%), or certain treatments like hyperbaric oxygen in the past month are disqualifiers.Check my eligibility
What is being tested?
The trial compares two standard-of-care wound treatments: Fibracol and Mirragen Wound Matrix for diabetic foot ulcers. It's a prospective study where patients are randomly assigned to either treatment group across multiple centers.See study design
What are the potential side effects?
While specific side effects aren't listed here, typical risks may include irritation at the application site, allergic reactions to materials used in dressings or matrices, infection risk due to open wounds especially if not properly managed according to protocol.

Treatment Details

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
Percentage of index ulcers healed at 12 weeks
Secondary outcome measures
Change in pain levels during trial, using the NPRS pain scale which measure pain on a range of 0-10, zero being no pain and 10 being the most severe pain
Changes in peripheral neuropathy using Semmes Weinstein Monofilament "10" point discrimination test
Changes in wound quality of life using Wound-Q
+3 more
Other outcome measures
Difference in cellulitis and/or infection
Use of near-infrared tissue oxygenation imaging
