What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Indacaterol 150 μgDrug
Indacaterol was supplied in powder filled capsules together with a single-dose dry-powder inhaler (SDDPI) device.
Placebo to indacaterolDrug
Placebo to indacaterol was supplied in powder filled capsules together with a single-dose dry-powder inhaler (SDDPI) device.
| Study group | Role | What they receive |
|---|---|---|
| Indacaterol 150 μg | Experimental | Patients inhaled indacaterol 150 μg once daily in the morning between 8:00 AM and 11:00 AM via a single-dose dry-powder inhaler (SDDPI) for 12 weeks. Daily inhaled corticosteroid treatment (if applicable) was to remain stable throughout the study. The short-acting β2-agonist salbutamol/albuterol was available for rescue use throughout the study. Receives: Drug: Indacaterol 150 μg |
| Placebo to indacaterol | Placebo comparator | Patients inhaled placebo to indacaterol once daily in the morning between 8:00 AM and 11:00 AM via a single-dose dry-powder inhaler (SDDPI) for 12 weeks. Daily inhaled corticosteroid treatment (if applicable) was to remain stable throughout the study. The short-acting β2-agonist salbutamol/albuterol was available for rescue use throughout the study.

What is being measured
The primary outcome is the main question the study is designed to answer.
Trough Forced Expiratory Volume in 1 Second (FEV1) 24 Hours Post-dose at the End of the Study (Week 12 + 1 Day, Day 85)
FEV1 was measured with spirometry conducted according to internationally accepted standards. Trough FEV1 was defined as the average of measurements made 23 hours 10 minutes and 23 hours 45 minutes post-dose at the end of treatment. The analysis included baseline FEV1, FEV1 pre-dose and 30 minutes post-dose of salbutamol during screening, and FEV1 pre-dose and 1 hour post-dose of ipratropium during screening as covariates.
Measured: 24 hours post-dose at the end of the study (Week 12 + 1 day, Day 85)
Secondary outcomes (1)
Trough Forced Expiratory Volume in 1 Second (FEV1) 24 Hours Post-dose on Day 2
FEV1 was measured with spirometry conducted according to internationally accepted standards. Trough FEV1 was defined as the average of measurements made 23 hours 10 minutes and 23 hours 45 minutes post-dose at the end of treatment. The analysis included baseline FEV1, FEV1 pre-dose and 30 minutes post-dose of salbutamol during screening, and FEV1 pre-dose and 1 hour post-dose of ipratropium during screening as covariates.
Measured: 24 hours post-dose on Day 2

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Indacaterol 150 μg in people with Chronic Obstructive Pulmonary Disease, run by Novartis at 120 sites in 3 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 18 Aug 2011. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 120 sites in United States, Belgium, New Zealand. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 18 Aug 2011). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Trough Forced Expiratory Volume in 1 Second (FEV1) 24 Hours Post-dose at the End of the Study (Week 12 + 1 Day, Day 85) (time frame: 24 hours post-dose at the end of the study (Week 12 + 1 day, Day 85)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00624286, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Aug 2011.
