Brief Summary
-----------------
224 adults with diabetic foot ulcers will be randomized to either magainin peptide (MSI-78) or ofloxacin (FLOXIN, Ortho-McNeil Pharmaceutical Corporation) an oral fluoroquinolone antibiotic.

Detailed Description
-----------------
Approximately 224 adults will be enrolled in an outpatient Phase III study to compare the safety and efficacy of topically applied magainin peptide (MSI-78) to that of ofloxacin (FLOXIN, Ortho-McNeil Pharmaceutical Corporation) an oral fluoroquinolone antibiotic, in the treatment of infected diabetic foot ulcers. This is a randomized, controlled, double-blind trial that will involve twenty or more clinical centers.
