Overview
Brief Summary
The purpose of this study is to evaluate the safety and pharmacokinetics of MEDI8852 compared to placebo when administered to healthy adult subjects.
Detailed Description
This is a phase 1, single-dose, double-blind, placebo-controlled, dose-escalation study to evaluate the safety and pharmacokinetics of MEDI8852 compared to placebo when administered to healthy adult subjects. Approximately 40 subjects will be entered to receive treatment across 4 fixed dose cohorts at 1 site. Investigational product will be delivered intravenously (IV). A total of 4 different dose levels of investigational product will be evaluated across the cohorts. Subjects will be followed for approximately 100 days.
