• Prior to randomization, subject must be a responder to ozone (also Part 2).

Part 2

• Subject with a diagnosis of COPD for at least 1 year and FEV1 ≥65% of predicted value post bronchodilation (measurement 30 minutes after 400 mcg salbutamol administration) and FEV1/FVC of <70%.

• Subject of either sex and of any race between the age of 40 and 65 years, with a BMI between 19 and 32.
