A Study of Tralokinumab When Delivered Subcutaneously at Different Flow Rates to Healthy Volunteers

A Phase 1 Study to Evaluate the Pharmacokinetics and Tolerability of a Single Subcutaneous Dose of Tralokinumab When Delivered as a 2 mL Injection at Different Flow Rates to Healthy Volunteers

The primary objective of this study is to evaluate the pharmacokinetics (PK) and tolerability of tralokinumab when delivered subcutaneously at different flow rates to healthy volunteers.

This is a Phase 1, open-label, assessor-blind, parallel-group study to evaluate the PK and tolerability of a single subcutaneous dose of 300 milligram (mg) tralokinumab when delivered as a 2 milliliters (mL) injection at different flow rates to healthy adult volunteers.
