Brief summary
The purpose of this study was to determine whether a fixed dose combination of indacaterol and glycopyrronium (QVA149) has an impact on night-time blood oxygen levels in Chronic Obstructive Pulmonary Disease.

Eligibility
Inclusion criteria
* Clinical diagnosis of COPD (according to GOLD guidelines, updated 2014) with a post-bronchodilator FEV1/FVC \<0.70 * Patients with a post-bronchodilator FEV1 ≥30% and \<60% of the predicted normal value * Resting daytime oxygen saturation levels measured by pulse oximetry of ≤95% SpO2 * Smoking history of at least 10 pack years (Ten pack-years are defined as 20 cigarettes a day for 10 years, or 10 cigarettes a day for 20 years)
Exclusion criteria
* An exacerbation of COPD (treatment with oral or parenteral antibiotics and/or glucocorticosteroids and/or hospitalization related to COPD) within 4 weeks prior to screening or during the run-in period * Diagnosed asthma * Patients receiving regular long term oxygen therapy (LTOT) * Ongoing / planned rehabilitation during the study period * Three or more awakenings during the night leading to toilet visit or other reasons for exiting the bed during the last week prior to the screening visit due to non-COPD reasons Other protocol-defined inclusion/
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Mean Night-time Blood Oxygenation | Post 4 weeks administration of QVA149, post 4 weeks administration of placebo | The mean night-time blood oxygenation following 4 weeks administration of QVA149 compared to placebo was assessed. Night time oxygenation (SpO2) was measured using polygraphy. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Percent of Time Spent During the Night Below 90 % in Blood Oxygen Saturation | Post 4 weeks administration of QVA149, post 4 weeks administration of placebo | The time during the night spent below 90 % in blood oxygen saturation following 4 weeks administration of QVA149 compared to placebo was assessed. Night time oxygenation (SpO2) was measured using polygraphy. |

Outcome results
Mean Night-time Blood Oxygenation
The mean night-time blood oxygenation following 4 weeks administration of QVA149 compared to placebo was assessed. Night time oxygenation (SpO2) was measured using polygraphy.
Time frame: Post 4 weeks administration of QVA149, post 4 weeks administration of placebo
Population: Only randomized participants with data from both treatments were analyzed.
| Arm | Measure | Value (LEAST_SQUARES_MEAN) | Dispersion |
|---|---|---|---|
| QVA149 (Indacaterol/Glycopyrronium) | Mean Night-time Blood Oxygenation | 89.59 Percent Oxygenation | Standard Error 0.3 |
| Placebo | Mean Night-time Blood Oxygenation | 90.04 Percent Oxygenation | Standard Error 0.28 |
Percent of Time Spent During the Night Below 90 % in Blood Oxygen Saturation
The time during the night spent below 90 % in blood oxygen saturation following 4 weeks administration of QVA149 compared to placebo was assessed. Night time oxygenation (SpO2) was measured using polygraphy.
Time frame: Post 4 weeks administration of QVA149, post 4 weeks administration of placebo
Population: Only randomized participants with data from both treatments were analyzed.
| Arm | Measure | Value (LEAST_SQUARES_MEAN) | Dispersion |
|---|---|---|---|
| QVA149 (Indacaterol/Glycopyrronium) | Percent of Time Spent During the Night Below 90 % in Blood Oxygen Saturation | 44.37 Percent | Standard Error 5.09 |
| Placebo | Percent of Time Spent During the Night Below 90 % in Blood Oxygen Saturation | 36.58 Percent | Standard Error 4.84 |
