E-101 solution is a first-in-class myeloperoxidase-mediated antimicrobial developed for topical application. It is composed of porcine myeloperoxidase (pMPO), glucose oxidase (GO), glucose, sodium chloride, and specific amino acids in an aqueous solution.

ABSTRACTThis study summarizes the topical E-101 solution susceptibility testing results for 760 Gram-positive and Gram-negative target pathogens collected from 75 U.S. sites between 2008 and 2012 and 103 ESKAPE pathogens. E-101 solution maintained potent activity against all bacterial species studied for each year tested, with MICs ranging from <0.008 to 0.25 μg porcine myeloperoxidase (pMPO)/ml. These results confirm that E-101 solution retains its potent broad-spectrum activity against U.S. clinical isolates and organisms with challenging resistance phenotypes.

ABSTRACT
We evaluated the
in vitro
and
in vivo
activity of a novel topical myeloperoxidase-mediated antimicrobial, E-101 solution, against 5 multidrug-resistant
Acinetobacter baumannii
isolates recovered from wounded American soldiers. Time-kill studies demonstrated rapid bactericidal activity against all
A. baumannii
strains tested in the presence of 3% blood. The
in vitro
bactericidal activity of E-101 solution against
A. baumannii
strains was confirmed in a full-thickness excision rat model. Additional
in vivo
studies appear warranted.
