Final Study Results Show V.A.C.(R) Therapy to be More Efficacious Than Advanced Moist Wound Therapy in Treating Diabetic Foot Ulcers

Results to be Published in ADA Journal "Diabetes Care"

SAN ANTONIO--(HSMN NewsFeed)--Kinetic Concepts, Inc. (NYSE:KCI ) today announced the final efficacy results of a randomized controlled clinical trial (RCT) on the clinical efficacy of KCI’s V.A.C.® System negative pressure wound therapy (NPWT) compared to advanced moist wound therapy (AMWT) to treat diabetic patients with foot ulcers. The study, which showed that V.A.C. Therapy is more efficacious than AMWT in the treatment of Diabetic Foot Ulcers, will be published in the April 2008 issue of Diabetes Care, the peer-reviewed journal of the American Diabetes Association. A pre-print version of the article is currently available online at

Highlights of the multi-center, RCT trial include:

  • A greater proportion of foot ulcers achieved complete ulcer closure with V.A.C. Therapy versus AMWT;
  • Time to wound closure was less with V.A.C. Therapy than with AMWT;
  • Patients on V.A.C. Therapy experienced significantly fewer amputations.

“Chronic Diabetic Foot Ulcers present a significant challenge to treating physicians,” said Dr. Peter A. Blume, North American Center for Limb Preservation and principal investigator for the study. “As observed in this clinical trial, the use of V.A.C. Therapy in concurrence with debridement of the wound increased the number of Diabetic Foot Ulcers healed, and decreased the number of amputations as compared to AMWT.”

The study is the largest RCT to date comparing V.A.C. Therapy with AMWT in the treatment of this wound type. It involved 342 patients with complex, hard-to-heal Diabetic Foot Ulcers with 90% of therapy days occurring in the home care setting. In the study, for patients on V.A.C. Therapy, complete ulcer closure was significantly greater than for those patients on AMWT (43.2% vs. 28.9%, p=0.007). Patients treated with V.A.C. Therapy healed significantly (p=0.001) faster (Kaplan-Meier median estimate time to 100% ulcer closure = 96 days) compared to AMWT (time to 100% ulcer closure not determinable). In addition, significantly fewer amputations were observed in V.A.C. Therapy patients compared to AMWT (4.1% vs. 10.2%, p=0.035). In assessing safety, the study showed that no significant difference between the groups was observed.

“This study further confirms results of a similar study of amputated diabetic foot wounds published in The Lancet on November 12, 2005,” said Dr. Dan Ciaburri, KCI’s Chief Medical Officer. “It also adds to KCI’s significant body of clinical data that clearly shows that our V.A.C. Therapy system, including its unique foam dressing, provides clinical advantage for treatment of Diabetic Foot Ulcers.”
