The goal of this clinical research study is to learn if giving a larger than normal "loading dose" of the antibiotic vancomycin before starting standard vancomycin dosing can help patients reach and maintain the needed blood-level of the antibiotic during treatment.

Primary Outcome Measures:
  • Percent of Participants Attaining Target Trough of 15-20 mg/L Following 30 mg/kg Loading Dose [ Time Frame: Up to 5 days ] [ Designated as safety issue: No ]
    Peak level (PK blood samples) drawn 4 hours after the completion of loading dose. Sequential trough levels drawn 30 minutes before each standard vancomycin dose for the next 4 doses. PK testing measures the amount of study drug in the body at different time points, with trough testing following 5 doses (1 dose every 8 to 12 hours).

Enrollment: 1
Study Start Date: June 2010
Study Completion Date: January 2012
Primary Completion Date: January 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Vancomycin Loading
Loading dose 30 mg/kg via central or peripheral intravenous infusion. Subsequent doses of vancomycin (15 mg/kg) are considered standard of care.
Drug: Vancomycin
Loading dose 30 mg/kg via central or peripheral intravenous infusion. Subsequent doses of vancomycin (15 mg/kg) are considered standard of care.

Detailed Description:

The Study Drug:

Vancomycin is an antibiotic used to treat serious, life-threatening infections caused by bacteria. Researchers want to find the best and most effective dose and blood-level of the drug that may have the best effect against bacteria.

Study Drug Administration:

If your doctor believes you are eligible, and you agree to take part in this study, you will be given a "loading dose" of vancomycin that is about twice as large as the standard dose. The dose amounts will be based on your body weight. Doses can be given every 8-12 hours, depending on your level of kidney function.

Study Procedures:

Blood (about 1 teaspoon each time) will be drawn for pharmacokinetic (PK) testing and to check your kidney function. PK testing measures the amount of study drug in the body at different time points. PK blood samples will be drawn just after the loading dose, and then just before each standard dose of vancomycin (up to 5 samples total). When possible, the PK sample may be drawn through a central venous catheter or line you already have placed, to avoid extra "needle sticks."

The study staff will collect information about your health and any side effects you may be having for 7 days.

Length of Study:

Treatment with vancomycin may be stopped early if you experience intolerable side effects or the doctor thinks you can stop taking the drug early.

This is an investigational study. Vancomycin is FDA approved and commercially available for use in treating bacterial infection. The use of a loading dose for vancomycin is investigational.

Up to 10 patients will take part in this study. All will be enrolled at M. D. Anderson.
