Summary

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.

Conditions

Interventions

BIOLOGICAL

Lyophilized mepolizumab

Mepolizumab will be provided as white, uniform, lyophilized cake in vials with unit dose strength of 100 mg/vial for reconstitution in 1.2 mL sterile water for injection (SWFI). Following reconstitution it forms a clear to opalescent, colorless to pale yellow solution for SC injection.

BIOLOGICAL

Liquid mepolizumab

Mepolizumab will be provided as a clear to opalescent, colorless to pale yellow sterile solution for SC injection, supplied in a single-use, prefilled autoinjector or safety syringe containing 100 mg/mL mepolizumab with sodium phosphate, citric acid, sucrose ethylenediaminetetraacetic acid and polysorbate 80.

DEVICE

Prefilled autoinjector

Single use, disposable autoinjector will be assembled with the prefilled syringe containing the drug product. It will enable automatic delivery of the drug product under the power of a spring mechanism following activation of the device. Start and end of injection clicks will inform the user of correct use. A plastic needle will cover shield the needle before and after injection to minimize the potential for needle stick injuries.

DEVICE

Prefilled Safety Syringe

Single use, disposable safety syringe with a retracting needle guard and locking system.
