Safety and Efficacy of QAX576 in Patients With Idiopathic Pulmonary Fibrosis (IPF)

Randomized, Double-blind, Placebo-controlled, Multiple-dose, Exploratory Proof of Concept Study to Assess the Safety, Tolerability, Efficacy, Pharmacodynamic (PD) and Pharmacokinetics of QAX576 in Patients With Rapidly Progressive IPF

This study is designed to evaluate the safety, tolerability, pharmacokinetics and efficacy of QAX576 in patients with idiopathic pulmonary fibrosis.

Inclusion criteria

• Diagnosis of Idiopathic Pulmonary Fibrosis (IPF), based on an appropriate clinical definition of IPF as detailed in the ATS/ERS/JRS/ALAT Statement: Idiopathic Pulmonary Fibrosis: Evidence-based Guidelines for Diagnosis and Management Diagnosis must be confirmed by a diagnostic HRCT or surgical lung biopsy.
• A 6-minute walk test (6MWT) distance ≥50 meters at Screening (use of supplemental oxygen allowed).

Exclusion criteria

• Smokers (use of tobacco products in the previous 3 months). Urine cotinine levels will be measured during screening for all subjects. Smokers will be defined as any subject who reports tobacco use or has a urine cotinine levels in the range defined as 'smokers' per the local lab.
• Lung residual volume > 120% predicted at Screening.
