Group 2 names the comparator: usual care.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | FF/VI 100 mcg/25 mcg | Participants were prescribed one inhalation of fluticasone furoate /vilanterol (FF/VI) 100 mcg/25 mcg via dry powder inhaler (DPI) once daily in the morning for 12 months in lieu of existing maintenance therapy. Participants on previous triple therapy received LAMA therapy additionally. | 94 | 1,396 | OG001 |
| Group 2 | Usual Care | Participants continued their existing maintenance therapy that included one of the following: an inhaled corticosteroid (ICS) alone or Long Acting Beta Agonist (LABA) alone or Long Acting Muscarinic Antagonist (LAMA) alone or combination of any two (ICS+LABA/ ICS+LAMA/ LABA+LAMA) or triple therapy (ICS+LABA+LAMA) at the appropriate dosing schedule, for 12 months | 83 | 1,403 | OG000 |

Outcome
- Type
- SECONDARY
- Title
- Number of Participants With Serious Adverse Events (SAEs) of Pneumonia During the Study
- Description
Incidence of SAE of pneumonia was defined for each randomized treatment group as the proportion (number) of participants in that group who experienced at least one SAE of pneumonia in the Pneumonia Adverse Event of Special Interest subgroup during the treatment period (from start date of exposure to stop date of exposure + 28 days). Non-inferiority is demonstrated if the upper limit of the two-sided 95% confidence interval for the incidence ratio is less than 2. Serious Adverse Events of pneumonia are defined by the Pneumonia Special Interest Group, which for SAEs of pneumonia collected for these subjects includes the following preferred terms: Pneumonia, Pneumonia aspiration, Aspergillus infection, Empyema, Pneumonia streptococcal, Pneumonitis, Pulmonary tuberculosis.
- Time frame
- Up to 58 weeks
- Population
- The Intent-to-Treat (ITT) Population: Defined as all participants who were randomised and received at least one prescription of study medication
