Change from Baseline in Diastolic blood pressure (DBP) and systolic blood pressure (SBP) | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
End point description |
SBP and DBP were measured in supine position after 5 minutes rest. Baseline values for each assessment was the latest available assessment prior to receiving the single dose of mepolizumab. Change from Baseline was defined as difference between the post-Baseline visit value and the Baseline value. Only those participants available at the specified time points (represented by n=X in the category titles) were analyzed.

End point description |
Single measurements of 12-lead ECGs were obtained after 5 minutes of rest in a supine position for the participant. ECG was performed on Day 1 and Day 85 using an automated ECG machine. Baseline values for each assessment was the latest available assessment prior to receiving the single dose of mepolizumab. Change from Baseline was defined as difference between the post-Baseline visit value and the Baseline value. Participants with abnormal ECG findings that are clinically not significant and clinically significant data has been presented here. The data of worst case post-Baseline is presented here. Only those participants available at the specified time points were analyzed.

End point title |
Number of participants with positive anti-mepolizumab binding antibodies | ||||||||||||||||||||
End point description |
Blood samples were collected for the determination of anti-mepolizumab antibodies. A binding anti-drug antibody (ADA) assay was performed. There were three tiered analysis: screening, confirmation and titration. The results of binding ADA were categorized as negative, transient positive (defined as a single confirmatory positive immunogenic response that does not occur at the final study assessment) or persistent positive (defined as a confirmatory positive immunogenic response for at least 2 consecutive assessments excluding the Screening visit, or a single result at the final study assessment). A participant was considered positive if they had at least one positive post-Baseline ADA result. Number of participants with positive anti-mepolizumab antibodies at any time post-Baseline are presented here. Only those participants available at the specified time points were analyzed.

Blood samples were collected for the determination of positive neutralizing antibodies. A neutralizing antibody assay was performed. Neutralizing antibody test was only carried out for participants who have had a positive confirmatory binding antibody test result at visit. A participant was considered positive if they had at least one positive post-Baseline neutralizing antibody result. Number of participants with positive neutralizing antibodies at any time post-Baseline are presented here. Only those participants available at the specified time points were analyzed.
