A Randomised, Double-blind, Active-controlled Study to Evaluate the Impact of Stepwise Withdrawal of Inhaled Corticosteroid Treatment in Patients With Severe to Very Severe Chronic Obstructive Pulmonary Disease (COPD) on Optimized Bronchodilator Therapy

This is a randomised study to be conducted in patients with severe to very severe Chronic Obstructive Pulmonary Disease (COPD) to establish whether there is a need for these patients to be continuously treated with an inhaled corticosteroid on top of two potent long-acting bronchodilators. The study also aims to identify the type of patients who are likely to benefit from inhaled corticosteroid maintenance therapy.
