Principal Investigator



This randomized, multicenter, double-blind, placebo-controlled, parallel-group study will evaluate the efficacy and safety of lebrikizumab as monotherapy in the absence of background idiopathic pulmonary fibrosis (IPF) therapy or as combination therapy with pirfenidone background therapy in participants with idiopathic pulmonary fibrosis. Participants will be randomized to receive either lebrikizumab or placebo subcutaneously (SC) every 4 weeks.

Official Title

A Phase II, Randomized, Double-Blind, Placebo-Controlled, Study to Assess the Efficacy and Safety of Lebrikizumab in Patients With Idiopathic Pulmonary Fibrosis


Idiopathic Pulmonary Fibrosis Pirfenidone Antibodies, Monoclonal
