Interleukin-13 (IL-13) is a pleiotropic cytokine that promotes inflammation, airways hyper-responsiveness (directly and through recruitment and activation of inflammatory cells), mucus hypersecretion, airway remodeling via fibrosis, increased immunoglobulin E (IgE) synthesis and mast cell activation.Tralokinumab (CAT-354) is a human immunoglobulin G4 (IgG4) anti-IL-13 monoclonal antibody that has been shown to potently and specifically neutralize IL-13 in preclinical models.This study will evaluate the PK profile of a single dose of tralokinumab administered subcutaneously at a dose of 300 mg in adolescent subjects with asthma to be compared with the PK data from completed studies in adults.
