Effect of AIN457 on Ozone-induced Airway Neutrophilia Compared to Placebo and Corticosteroid in Healthy Subjects

Double Blind, Placebo Controlled, Parallel Group Study With an Open Label Reference Arm to Assess the Effects of Intravenously Administered AIN457 on Ozone Induced Neutrophilia Compared to Placebo & Oral Corticosteroid in Healthy Volunteers

This study will assess the ability of AIN457 to attenuate the increase in airway neutrophils that is seen following ozone exposure. Healthy subjects will be treated with AIN457, placebo, or oral corticosteroid and the response to a subsequent ozone exposure will be evaluated.

Inclusion criteria:

• Healthy subjects
• Normal sputum neutrophil levels at screening
• Ozone responsive

Exclusion criteria:

• Smokers
• Prior treatment with antibody treatment or immunosuppressive agent
• Presence or history of a major chronic inflammatory autoimmune disease
• History of severe hypersensitivity to any biological agents (antibody or soluble receptor), a history of serious allergic reaction, collagen disease, neurological disease (including demyelinating disease).

Other protocol-defined inclusion/exclusion criteria may apply
