First Time in Human Study of Protexia
Summary
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics and immunogenicity of Protexia, an experimental drug being developed to protect soldiers against the effects of nerve agents. Volunteers will be entered into one of five groups. Four of the groups will receive a single intramuscular dose of Protexia or saline placebo on Study Day 1 and will participate in the study for approximately 71 days. One of the groups will receive two intramuscular doses of Protexia or saline placebo - one dose on Study Day 1 and the second dose on Study Day 72. This group will participate in the study for approximately 142 days. All volunteers will remain at the study site as an inpatient for three days after they are dosed and will be monitored closely by the study doctors and staff. After that, volunteers will return to the study site as outpatients at predetermined intervals. Groups 1, 2, 4, 5 will have a total of 6 follow-up visits and Group 3 will have a total of 12 follow-up visits. It is expected that this study will provide important information on the safety and tolerabiity of Protexia at one and two doses.
