Official title
An Open Label, Randomised, Three Arm, Single Dose, Multicentre, Parallel Group Study in Healthy Subjects to Compare the Pharmacokinetics of Subcutaneous Mepolizumab When Delivered as a Liquid Drug Product in a Safety Syringe or an Auto Injector With a Reconstituted Lyophilised Drug Product From a Vial
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Mepolizumab (SB-240563) is a humanized monoclonal antibody (Immunoglobulin G1, kappa, mAb) that blocks human interleukin-5 (hIL-5) from binding to the interleukin (IL)-5 receptor complex expressed on the eosinophil cell surface and thus inhibits signaling. This study will compare the pharmacokinetics and safety of mepolizumab administered as a liquid drug product in two different devices with the reconstituted lyophilized drug product in healthy subjects. Subjects will receive a single administration of 100 milligram (mg) mepolizumab as a single injection. The randomization will be stratified by body weight (\<70 kilogram (kg), 70 \<80 kg and \>=80 kg) and the site of injection will be randomized 1:1:1 to the upper arm, abdomen or thigh. Approximately 243 healthy subjects will be randomized so that at least 9 subjects are randomized to each mepolizumab treatment within each weight strata and 3 subjects within each mepolizumab treatment, weight strata and injection site. Each subject will participate in the study for up to approximately 16 weeks (up to 85 days after drug administration), and will have a screening visit, a single dose treatment period, and a follow-up visit.
