Trial Outcomes & Findings for A Phase 2a Study to Evaluate the Safety and Tolerability of Benralizumab (MEDI-563) in Adults With Asthma (NCT NCT00783289)

NCT ID: NCT00783289

Last Updated: 2019-12-27

Results Overview

An adverse event (AE) was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. A serious adverse event (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent were events between first dose of study drug and up to Day 161 that were absent before treatment or that worsened relative to pre-treatment state.
