Study of Omiganan 1% Gel in Preventing Catheter Infections/Colonization in Patients With Central Venous Catheters
- Registration Number
- NCT00231153
- Lead Sponsor
- Cadence Pharmaceuticals
- Brief Summary
The purpose of this study is to determine whether treatment with topical omiganan is more effective than treatment with topical povidone-iodine in preventing local catheter site infections and catheter colonization in patients who have central venous catheters.
- Detailed Description
Study design:
This is a phase 3, multi-center, randomized, Evaluation Committee-blinded study in patients undergoing noncuffed central venous catheterization using either a single lumen or multi-lumen catheter, and for whom the catheter is expected to be in place for at least 48 hours and for no longer than 28 days. Patients will be randomized within 4 hours of the insertion of the first study CVC.
The first study catheter for all patients must be a noncuffed (nontunneled) central venous catheter (CVC). Additionally, only catheters inserted using povidone iodine to prepare the insertion site are eligible to become study catheters. CVCs will be inserted either into the axillary, jugular, subclavian, or femoral vein. Following the first study CVC insertion, additional CVCs, as well as arterial catheters and PICC lines will be allowed as study catheters. Only catheters that have not been impregnated with an antimicrobial substance (e.g. bonded catheters, antimicrobial impregnated, silver tipped, etc) may be used as study catheters. Study catheters must have a skin/catheter interface; for example, introducers will be allowed as study catheters but any catheter, including a CVC, inserted through the introducer will be deemed a non-study catheter. Once a patient has been randomized to either treatment, all study catheters will receive the same treatment.
NIH (NCID) and/or local hospital guidelines will be followed for maximal sterile barrier precautions. The catheter site will be disinfected using 10% povidone iodine for a minimum of 2 minutes per established CDC guidelines prior to catheter insertion. Patients randomized to the omiganan 1% gel group will receive an application of omiganan 1% gel around the catheter insertion site following catheter insertion. Patients randomized to the povidone iodine group will receive no further antisepsis treatment other than cleansing the site with povidone iodine at dressing changes. For patients in both groups, the catheterization site will be covered with a semitransparent dressing provided by the sponsor.
Every 3 days the dressing will be changed. Skin irritation, erythema and edema will be assessed as well as the presence of purulence, moisture, ecchymosis, abnormally warm tissue temperature and/or site pain/tenderness.
Patients will be discharged from the study following the removal of the final study catheter or on study day 28, whichever is sooner. Patients or their legal representatives will be contacted at least 28 days after study discharge/withdrawal for safety follow-up purposes.

- Primary Outcome Measures
Name Time Method Local Catheter Site Infection (LCSI) study completion LCSI was defined as a study catheter showing any 2 of the following criteria: erythema \>= 2; edema \>= 2; presence of purulence, pain, or abnormal study catheter site warmth. In addition, an action must have been taken that indicated a LCSI was present.
- Secondary Outcome Measures
Name Time Method Microbiologically-confirmed LCSI study completion MCLCSI is a subset of EC-adjudicated LCSI for any catheter where there is (1) growth of a recognized pathogen from a culture or any purulence or exudate from the same insertion site, or (2) a positive culture of the subcutaneous segment of the catheter meeting criteria for significant colonization.
Catheter Colonization (CC) study completion CC was defined as a positive culture of any catheter segment \>= 15 CFU (roll-plate method) or \>999 CFU/ml (sonication method) or a positive blood culture drawn via the catheter where the time-to-positivity difference of catheter line vs. peripheral blood \>120 minutes (catheter positive first).
