New Study Shows Diabetic Foot Ulcers Treated with OASIS® Ultra Tri-Layer Matrix Demonstrated Significantly Better and More Rapid Wound Closure Compared to Standard Care

Smith & Nephew (LSE: SN; NYSE: SNN), the global medical technology business, today announces that a new study published today in Advances in Wound Care has found that diabetic foot ulcers, a common and serious complication of diabetes, treated with OASIS Ultra Tri-Layer Matrix, an advanced wound management product, resulted in superior wound closure compared to standard of care treatments. The study demonstrated that weekly treatment with OASIS Ultra Tri-Layer Matrix over 12 weeks resulted in significantly more wound closures (54 percent versus 32 percent), greater reduction in wound size and achieved wound closure two weeks earlier than standard care.1 These data are also being presented on Friday, May 1 at the 2015 Symposium on Advanced Wound Care (SAWC) Annual Meeting in San Antonio, TX.

The randomized, controlled and open-label multicenter study enrolled 82 patients with type 1 or type 2 diabetes and compared wound management over 12 weeks plus an additional four-week follow up with OASIS Ultra Tri-Layer Matrix to standard of care methods for wound care, as selected by the study investigator, including silver dressings, hydrogel, wet-to-dry wound dressings and triple antibiotic dressings.  It is the first randomized, controlled and open-label study to evaluate OASIS Ultra Tri-Layer Matrix in the study population.

“Diabetic foot ulcers have a significant impact on a patient’s quality of life and place patients at higher risk for lower limb amputations,” said lead investigator Shawn M. Cazzell, DPM, Valley Vascular Surgery Associates, St. Agnes Medical Center in Fresno, CA. “In some cases, diabetic foot ulcers can be fatal if they fail to make healing progress and become infected. As such, it is critically important to identify effective treatments that promote rapid and complete wound closure. The results of the OASIS Ultra Tri-Layer Matrix study were quite powerful and underscore the need for a shift in the way doctors approach the management of foot ulcers in patients with diabetes.”

Additional Study Details:

“The results of this study are extremely encouraging and provide well validated evidence for the clinical value of OASIS Ultra Tri-Layer Matrix in the management of diabetic foot ulcers, consistent with prior trials of OASIS Wound Matrix,” said Bert Slade, MD, Chief Medical and Scientific Officer, Smith & Nephew Advanced Wound Management.

About Diabetic Foot Ulcers

Diabetes is among the most common chronic medical conditions, affecting 29.1 million people in the United States.2 Up to 25 percent of people with diabetes are at lifetime risk for diabetic foot ulcers, which are an enormous disease burden.3 They are frequently difficult to treat, costly, and can impact an individual’s quality of life, physical functioning and productivity.2 Diabetic foot ulcers often fail to heal due to poor blood glucose control, necrotic tissue, infection, chronic inflammation and inadequate perfusion. They are a leading cause of lower limb amputations and the most common reason for hospital admissions among people with diabetes.3

About OASIS Ultra Tri-Layer Matrix

The three-dimensional architecture of OASIS Ultra Tri-Layer Matrix is cleared to effectively manage wounds. The OASIS product’s naturally derived biomaterial—collagen, proteoglycans and glycoproteins—closely mimics normal skin ECM function, replacing key structural components that are missing or failing in wounds. In many patients, replacing these components can help restart the body’s own healing process.

OASIS Ultra Tri-Layer Matrix is indicated for the management of wounds including: partial and full-thickness wounds, pressure ulcers, venous ulcers, chronic vascular ulcers, tunneled/undermined wounds, diabetic ulcers, trauma wounds (abrasions, lacerations, second-degree burns, skin tears), draining wounds, surgical wounds (donor sites/grafts, post-Mohs’ surgery, post-laser surgery, podiatric, wound dehiscence).

OASIS Ultra Tri-Layer Matrix is derived from a porcine source and should not be used in patients with known sensitivity to porcine material. This product is not indicated for use in third-degree burns.
