Efficacy, Safety, Tolerability, and Pharmacokinetics of Indacaterol Maleate Via Concept1 or Simoon Devices

This study was double-blind with regards to the Concept1, where placebo for the lactose-blended indacaterol was available. However, with regards to the Simoon, neither the subject nor the investigator was blinded due to lack of a placebo to the PulmoSphere formulation. Hence, the overall designation of the study was partially-blind.
