The purpose of this study is to determine whether indacaterol maleate 300 micrograms (mcg) is effective in the acute treatment of COPD and in particular on reducing lung hyperinflation and dynamic volumes.

Condition Intervention Phase
COPD Lung Diseases Dyspnea Hypoxemia Tachycardia Drug: Indacaterol maleate Drug: Placebo Phase 4

Further study details as provided by Pierachille Santus, University of Milan:

Primary Outcome Measures:
  • Intra Thoracic Gas Volume (ITGV) [ Time Frame: 60 minutes after drug inhalation ]
    A complete body plethysmografic test will be performed after indacaterol inhalation

Secondary Outcome Measures:
  • Forced Expired Volume in the first second (FEV1) [ Time Frame: 60 minutes after drug inhalation ]
    Will be performed: spirometry, Arterial blood sample, measurement of blood pressure and cardiac frequency. All these parameters will be tested 60 minutes after inhalation of Indacaterol 300 micrograms (mcg).

  • Partial pressure of arterial oxygen (PaO2) [ Time Frame: 60 minutes after drug inhalation ]
    Arterial gas analysis will be performed evaluating all arterial gases

Enrollment: 60
Study Start Date: May 2011
Study Completion Date: September 2011
Primary Completion Date: August 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Bronchodilator
Indacaterol maleate 300 mcg will be administered by a third independent investigator following a randomization list.
Drug: Indacaterol maleate
Dry powered, 300 mcg, only one inhalation with 24 hours duration
Other Name: Onbrez, Hirobriz, Onbrize, Oslif Breezehaler, Arcapta
Placebo Comparator: Placebo
Will be administered with the same device by a third independent investigator
Drug: Placebo
Dry powered, same to study drug, only one inhalation

Detailed Description:

Enrolled patients: COPD of any disease severity in stable conditions. 48 hours of inhalatory drugs wash out.

Evaluation: Plethysmographic test, blood gas analysis, blood pressure, cardiac frequency and Borg scale evaluation in basal condition and after 60 minutes of indacaterol maleate 300 mcg inhalation.
