A Study of Lebrikizumab in Participants With Idiopathic Pulmonary Fibrosis (IPF)

CompletedPhase 2

Sponsor: Hoffmann-La Roche

Conditions: Idiopathic Pulmonary Fibrosis

Interventions: Lebrikizumab, Pirfenidone, Placebo

Countries: United States, Australia, Belgium, Canada, France, Germany, Italy, Japan

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 IPF therapy and as combination therapy with pirfenidone background therapy in participants with IPF. Participants will be randomized to receive either lebrikizumab or placebo subcutaneously every 4 weeks.

Eligibility overview

Sex: ALL

Age: 40 Years to —

Healthy volunteers: No

Study type: INTERVENTIONAL

Eligibility criteria

Inclusion Criteria:

* Have a diagnosis of IPF within the previous 5 years from time of screening and confirmed at baseline
