Study of Single Doses of IV Aerucin in Healthy Adults

This Phase I trial will be conducted as an open label trial in 15 healthy adults. All
subjects will receive a specific intravenous dose of Aerucin. There are three study groups,
each with a specific dose of Aerucin. Study Group 1 will receive 2.0 mg/ kg of Aerucin .
Study Group 2 will receive 8.0 mg/kg of Aerucin . Study Group 3 will receive 20 mg/kg of
Aerucin . The dose levels of Aerucin are selected for this study based on animal studies
showing protection in an animal model and absence of adverse effects in toxicological
studies. Groups will be enrolled sequentially.
