Brief summary
This is a randomized, 2-part, 2-arm, open-label, parallel-group, multi-center study to compare the PK of etrolizumab administered subcutaneously by an AI (test device) or a PFS-NSD (reference device) in healthy participants. The study will comprise a pilot cohort (Part 1) to estimate the geometric mean ratio (GMR) and variability of the maximum observed concentration (Cmax) and area under the concentration-time curve (AUC) to confirm or determine the sample size for the pivotal cohort (Part 2). The pivotal cohort will demonstrate exposure comparability of Cmax, AUC from Hour 0 to the last measurable concentration (AUClast), and AUC from Hour 0 to extrapolated infinite time (AUC0-inf), values for a single dose of etrolizumab administered subcutaneously either by the AI or the PFS-NSD.
Interventions
Etrolizumab will be administered at a dose of 105 milligrams (mg).
The pre-filled AI will be used to administer etrolizumab.
The PFS-NSD will be used to administer etrolizumab.
