Prevention of Infection Using a Topical Gentamicin-Collagen Sponge in Diabetic Patients With An Uninfected Foot Ulcer

2014-07-24 14:18:05 | BioPortfolio


The purpose of this study is to determine the safety and efficacy of the Collatamp G topical gentamicin collagen sponge (gentamicin sponge) combined with standard of care (daily wound care, off-loading, diabetic control and debridement by a physician or podiatrist), compared with placebo sponge combined with standard of care, in preventing infection of diabetic lower extremity skin ulcers.


Infected skin ulcers with diabetes can be very debilitating because they are difficult to heal. Diabetic ulcers are responsible for frequent health care visits, and are a major predictor of amputation. Diabetic ulcers can be caused by a patient's inability to sense pain or warmth as well as peripheral vascular disease, which causes diminished blood flow to the foot. Early aggressive treatment is necessary to prevent infection and ultimately prevent the need for amputation.

Gentamicin is an antibiotic that is effective in treating certain kinds of infection. Collagen is a protein that is found in all mammals. The gentamicin-collagen sponge is a thin flat sponge made out of collagen that comes from cow tendons and containing gentamicin. When applied to an open ulcer, the collagen breaks down and the gentamicin is released into the ulcer, but very little is absorbed into the blood stream. The high levels of gentamicin in the open infected ulcer may help treat the infection.

In this study, all subjects will be given the necessary supplies and taught how to take care their foot ulcer. Subjects will be randomly assigned to receive either the gentamicin-collagen sponge or a plain collagen sponge. The sponge will be applied into the ulcer twice a week during the treatment period.

Medical and Biotech [MESH] Definitions

Sterile, gelatin-base surgical sponge applied topically as an adjunct to hemostasis when the control of bleeding by conventional procedures is ineffective to reduce capillary ooze or is impractical. (From AMA Drug Evaluations Annual, 1994, p797)

A fibrillar collagen found widely distributed as a minor component in tissues that contain COLLAGEN TYPE I and COLLAGEN TYPE III. It is a heterotrimeric molecule composed of alpha1(V), alpha2(V) and alpha3(V) subunits. Several forms of collagen type V exist depending upon the composition of the subunits that form the trimer.

A fibril-associated collagen usually found crosslinked to the surface of COLLAGEN TYPE II fibrils. It is a heterotrimer containing alpha1(IX), alpha2(IX) and alpha3(IX) subunits.

A fibrillar collagen found primarily in interstitial CARTILAGE. Collagen type XI is heterotrimer containing alpha1(XI), alpha2(XI) and alpha3(XI) subunits.

A non-fibrillar collagen that forms a network of MICROFIBRILS within the EXTRACELLULAR MATRIX of CONNECTIVE TISSUE. The alpha subunits of collagen type VI assemble into antiparallel, overlapping dimers which then align to form tetramers.
