Safety and Efficacy of an Antibiotic Implant in Cardiac Surgical Subjects at Higher Risk for Sternal Wound Infection

Cardiac Surgery Clinical Trial

Official title: A Randomized, Controlled, Phase 3 Study of Gentamicin-Collagen Sponge in Cardiac Surgical Subjects at Higher Risk for Sternal Wound Infection

Status Completed

Clinical Trial Summary

The purpose of this study is to determine whether the gentamicin-collagen sponge is safe and effective in preventing sternal wound infections in patients undergoing cardiac surgery who are at a greater risk of developing sternal wound infections.

Clinical Trial Description

Sternal wound infection (SWI) is a significant problem in cardiac surgical subjects,in particular in those with risk factors such as diabetes and obesity. There is a long unmet need for an intervention that can reduce the incidence and severity of SWIs in high-risk subjects.

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 inserted into a surgical site, the collagen breaks down and the gentamicin is released at the site but very little is absorbed into the blood stream. The high levels of antibiotic at the surgical site may prevent an infection at the surgical site.

Outside of the United States more than 3,500 subjects have received treatment in clinical studies with the gentamicin-collagen sponge, primarily for orthopedic, intraabdominal, and cardiothoracic surgeries or wound infections following surgical procedures or traumatic events.

In this study, all subjects will be given treatment that is normally given to prevent surgical infections. For subjects randomly assigned to the gentamicin-collagen sponge treatment group, 2 sponges will be placed between the sternal halves during surgery. IMMEDIATELY before insertion of the sponge the surgeon should wet the sponge with saline as shown in the training/certification document. This wet sponge SHOULD BE INSERTED INTO THE STERNUM WITHIN APPROXIMATELY 15 SECONDS (AFTER THIS TIME IT MAY BECOME MORE DIFFICULT TO HANDLE). All subjects will be followed for 90 days after surgery to determine whether they develop a sternal wound infection. ;
