Group 2 names the comparator: placebo.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Omalizumab | Participants received omalizumab as a subcutaneous injection once every 2 weeks (q2w) or once every 4 weeks (q4w). The dose (from 75 mg up to 600 mg) and dosing frequency (q2w or q4w) was determined by serum total IgE level and body weight using the study-drug dosing table. All participants were also treated during the entire study with intranasal corticosteroids (mometasone nasal spray) as background therapy. | 20 | 42 | OG001 |
| Group 2 | Placebo | Participants received matching placebo as a subcutaneous injection once every 2 weeks or once every 4 weeks. The dose and dosing frequency was determined by serum total IgE level and body weight using the study-drug dosing table. All participants were also treated during the entire study with intranasal corticosteroids (mometasone nasal spray) as background therapy. | 9 | 32 | OG000 |

Outcome
- Type
- SECONDARY
- Title
- Number of Participants With a Change From Baseline at Week 24 in Asthma Quality of Life Questionnaire (AQLQ) of ≥0.5 in Participants With Comorbid Asthma Only
- Description
The AQLQ is a 32-item participant-reported measure of asthma-related quality of life (QoL) with a total score (the mean of all 32 responses) ranging from 1 (severely impaired) to 7 (not impaired at all); a higher score indicates a better QoL. An increase of at least 0.5 points in the AQLQ score was considered the minimal important difference for improvement in QoL.
- Time frame
- Baseline, Week 24
- Population
- Analysis was conducted only in the subgroup of participants with comorbid asthma at screening and AQLQ assessments at Baseline and Week 24.
