• Participant gender: All

Summary

This is a Phase 1, first time in human study enrolling approximately 33 healthy adult subjects (18-65 yrs) from one study site. The purpose of this study is to evaluate the safety, tolerability and PK of MEDI4893 in healthy adult volunteers administered as a single IV dose compared with placebo, across 4 cohorts. The 4 dose cohorts will enroll sequentially. Subjects will be followed for safety from the time of Informed Consent through 360 days post dose.
