A Multicenter, Randomized, Open-Label, Parallel Group Phase 1 Pharmacokinetic Comparability Study of Benralizumab Administrated Using Accessorized Pre-Filled Syringe (APFS) or Autoinjector (AI) in Healthy Volunteers.

An open-label, single dose Pharmacokinetic (PK) comparability study to demonstrate comparable drug exposure following Subcutaneous benralizumab administration by using accessorized pre-filled syringe (APFS) or autoinjector (AI) devices.

Study Overview

• Status: Completed
• Conditions: Chronic Obstructive Pulmonary Disease; Asthma
• Intervention / Treatment: Biological: Benralizumab

Detailed Description

A study of descriptive comparison of benralizumab PK by weight and injection site.

This study will be a multicenter, randomized, open-label, parallel group Phase 1 study designed to compare benralizumab PK exposure in healthy subjects following single subcutaneous (SC) administration of fixed 30 mg dose of benralizumab by using APFS and single-use AI. Eligible subjects will be healthy subjects aged 18 to 55 years, with a body weight of 55 to 100 kg and a body mass index of 18 to 29.9 kg/m2 . A total of 180 subjects will be randomized. Randomization will be stratified by weight group (55 to 69.9 kg, 70 to 84.9 kg and 85 to 100 kg), and within each of the 3 weight groups, subjects will be randomized 1:1:1:1:1:1 to 1 of the 6 combinations of treatment (APFS or AI) with injection site (upper arm, abdomen or thigh), presented in Table 1. This study will be performed at 2 study centers.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: Benralizumab by Accessorized Pre-Filled Syringe; Drug administration by Accessorized Pre-Filled Syringe. A total of 180 subjects will be randomized and will be stratified by weight group (55 to 69.9 kg, 70 to 84.9 kg and 85 to 100 kg). Within each of the 3 weight groups, subjects will be randomized 1:1:1:1:1:1 to 1 of the 6 combinations of treatment (APFS) with injection site (upper arm, abdomen or thigh)	Biological: Benralizumab; A humanized, afucosylated, monoclonal antibody (mAb) that binds specifically to the human IL-5 receptor alpha subunit (IL-5Rα) on the target cell.
Other: Benralizumab by Autoinjector; Drug administration by Autoinjector A total of 180 subjects will be randomized and will be stratified by weight group (55 to 69.9 kg, 70 to 84.9 kg and 85 to 100 kg). Within each of the 3 weight groups, subjects will be randomized 1:1:1:1:1:1 to 1 of the 6 combinations of treatment (APFS) with injection site (upper arm, abdomen or thigh)	Biological: Benralizumab; A humanized, afucosylated, monoclonal antibody (mAb) that binds specifically to the human IL-5 receptor alpha subunit (IL-5Rα) on the target cell.
