研究概览
简要总结
The purpose of this research study is to determine if omiganan 1% gel (the investigational medication in this research study) is effective and safe when compared to chlorhexidine 2% (an FDA approved medication) for killing bacteria (germs) that live on the surface of the skin. Both of the study medications are applied topically (on the surface of the skin).
详细描述
The study is comprised of 2 parts with approximately 20 subjects participating in each part.
Subjects eligible for Part 1 will have omiganan 1 % gel applied to 6 sites across the chest and/or abdomen and chlorhexidine 2% solution will be applied to 6 matching sites on the contralateral side.
Subjects eligible for Part 2 will each have omiganan 1% gel applied to 6 sites across the upper chest or abdomen.In addition,subjects in Part 2 will have 2 peripheral catheters inserted, one in each arm.One catheter insertion site will be treated with omiganan 1% gel (following treatment with isopropyl alcohol) and the other site will be treated with chlorhexidine 2%/isopropyl alcohol.

入选标准
- •Male and female subjects18-70 years of age
- •No evidence of dermatosis, dermatitis, inflammation, scarring, or acute injuries to the drug application sites on the chest or abdomen
- •Subjects must have screening samples from the skin on the right and left side of the chest or abdomen containing at least 2.5 log10 colony forming units per square centimeter (CFU/cm2 )organisms (from the average of 2 samples obtained during screening)
- •Willing to provide written informed consent.
排除标准
- •Allergies or sensitivities to alcohol, adhesive tape, bandages, latex, chlorhexidine gluconate, or any of the ingredients of omiganan 1% gel
- •Prior treatment with any systemic antibiotic, or any other product known to affect the normal microbial flora of the skin within 7 days of the screening examination
- •Requirement for topical antibiotic use on or within 10 cm of any study test site
- •Subjects who have been treated with any investigational drug (other than omiganan) within the previous 30 days, or who are participating in an investigational drug study at any time during the course of this study
- •Subjects who have been previously treated with omiganan and experienced a possibly related adverse event during the study Note: a wash out period of one week is required prior to participation in Part 2 of the study
- •A medical condition that the Investigator believes may interfere with the safety of the subject or the intent and conduct of the study Note: this includes conditions such as: severe eczema, psoriasis and/or dermal infections, old scars, insulin dependent diabetes mellitus, severe immunocompromising conditions, HIV infection, or use of medications that would interfere with assessment of study endpoints
- •A current or recent history of illicit drug or alcohol abuse
- •Subjects not willing or able to fulfill protocol requirements
- •Pregnancy. Women of childbearing potential who have a positive or equivocal result on a urine and/or blood pregnancy test before study enrollment will not be included
研究组 & 干预措施
omiganan 1% gel
Omiganan has a rapid bactericidal and fungicidal effect which is under development for the prevention of infections arising from short-term central venous catheters, as well as for the prevention of surgical wound infections in contaminated wounds.
干预措施: omiganan 1% gel (Drug)
chlorhexidine 2%
干预措施: chlorhexidine 2% solution (Drug)
结局指标
主要结局
Change in Mean Number of Skin Bacterial Counts From Baseline to 72 Hours
时间窗: Prior to first application (0 hours) to 72 hours post application
Change in the mean number of skin bacterial counts (CFU/cm2) which was calculated by subtracting log10 CFU/cm2 at 72 hours (single sample per subject per timepoint) from the log10 CFU/cm2 at 0 hours (baseline) in Part 2.Baseline was calculated by 'pooling' samples from 6 sites adjacent to each timepoint.
Change in Mean Number of Skin Bacterial Counts From Baseline to 7 Days
时间窗: Prior to first application (0 hours) to 7 days post application.
Change in the mean number of skin bacterial counts (log 10 CFU/cm2)which was calculated by subtracting log10 CFU/cm2 at 7 days (one sample per site per subject per timepoint) from log10CFU/cm2 at 0 hours in Part 2.Baseline was calculated by 'pooling' samples from 6 sites adjacent to each timepoint.
Number of Subjects With Significantly Colonized Catheters, Defined as > or = to 15 Colony Forming Units- CFUs)
时间窗: Each sampling point and the rate of catheter colonization for each treatment 72 hours to 7 days.
Roll plate cultures (quantitative) measured CFU on catheter tips after removal up to 7 days after insertion.
