|---|---|---|---|
| Primary | Occurrence of One or More Asthma Exacerbations (All Treatment Steps [Steps 2-5]) | 90 Day outcome period | Asthma exacerbation defined as a prescribed course of systemic steroids by a clinician or initiation of a course of systemic steroids by a participant or a hospitalization during the fall outcome period (90 day period beginning on the first day of the participant's school year) to prevent a serious asthma outcome. If a participant initiates and completes a course of systemic steroids without clinician involvement, this course will be counted only if it meets the following minimum dosage: prednisone, prednisolone, or methylprednisolone at ≥ 20mg per day for 3 of any 5 consecutive days; or dexamethasone at ≥10mg per day for ≥1 day. Odds ratio comparing Placebo and Omalizumab arms across all treatment steps (Steps 2-5). |
| Primary | Occurrence of One or More Asthma Exacerbations (Treatment Steps 2-4) | 90 Day outcome period | Asthma exacerbation defined as a prescription of a course of systemic steroids by a clinician or initiation of a course of systemic steroids by a participant or a hospitalization during the fall outcome period (90 day period beginning on the first day of the participant's school year) to prevent a serious asthma outcome. If a participant initiates and completes a course of systemic steroids without clinician involvement, this course will be counted only if it meets the following minimum dosage: prednisone, prednisolone, or methylprednisolone at ≥20mg per day for 3 of any 5 consecutive days; or dexamethasone at ≥10mg per day for ≥1 day. Odds ratio comparing Inhaled corticosteroid boost therapy (ICS) and Omalizumab arms at Treatment Steps 2-4. |
| Secondary | Virus-induced Exacerbations as Measured by an Exacerbation That is Associated With a Virus Detected Using the Nasal Mucus Samples | 90 Day outcome period | Asthma exacerbation:defined by a prescribed course of systemic steroids by a clinician or initiation of a course of systemic steroids by a participant or a hospitalization during the fall outcome period (90 day period beginning on the 1st day of the participant's school year) to prevent a serious asthma outcome. If a participant initiates and completes a course of systemic steroids without clinician involvement, this course will be counted only if it meets the following minimum dosage: prednisone, prednisolone, or methylprednisolone at ≥ 20mg per day for 3 of any 5 consecutive days; or dexamethasone at ≥ 10mg per day for ≥1 day. Exacerbations were then associated with viral respiratory infections based on nasal mucus samples collected monthly. Nasal mucus samples were categorized as having exacerbations or not having exacerbations. Participants could potentially be counted in each group, as participants could have samples with exacerbations and samples without exacerbations. |
| Secondary | Severity of Asthma Symptoms Associated With a Viral Infection:Omalizumab vs. Placebo | 90 Day outcome period | Severity asthma symptoms is defined as the highest value among the following 3 variables: number of days with wheezing, tightness in the chest, or cough; number of nights with disturbed sleep as a result of asthma; and number of days on which a participant had to slow down or discontinue play/physical activities over a two week period associated with a viral infection. This outcome looks at the effect by group on number of days with asthma symptoms and infections. The hypothesis behind this outcome measure is that omalizumab will change virology; thus, the the intent of this measure was to assess the comparator group of placebo against omalizumab |
| Secondary | Number of Exacerbations Evaluated Monthly With Viral Respiratory Infections: Omalizumab vs. Placebo | 90 Day outcome period | Asthma exacerbation is defined as a prescribed course of systemic steroids by a clinician or initiation of a course of systemic steroids by a participant or a hospitalization during the fall outcome period (90 day period beginning on the first day of the participant's school year) to prevent a serious asthma outcome. If a participant initiates and completes a course of systemic steroids without clinician involvement, this course will be counted only if it meets the following minimum dosage: prednisone, prednisolone, or methylprednisolone at ≥20mg per day for 3 of any 5 consecutive days; or dexamethasone at ≥10mg per day for ≥1 day. The hypothesis behind this outcome measure is that omalizumab will change virology; thus, the intent of this measure was to assess the comparator group of placebo against omalizumab. |
| Secondary | Composite Asthma Severity Index (CASI), Treatment Steps 2-5: Omalizumab vs. Placebo | 90 Day outcome period | CASI scores include 5 domains: day symptoms and albuterol use, night symptoms and albuterol use, controller treatment, lung function measures, and exacerbations. To calculate CASI, the 5 domain scores are summed to determine a final score, which can range from 0 to 20, with 0 being no severity of asthma and 20 being extremely severe asthma. |
| Secondary | Composite Asthma Severity Index (CASI), Treatment Steps 2-4: Omalizumab vs. ICS | 90 Day outcome period | CASI scores include 5 domains: day symptoms and albuterol use, night symptoms and albuterol use, controller treatment, lung function measures, and exacerbations. To calculate CASI, the 5 domain scores are summed to determine a final score, which can range from 0 to 20, with 0 being no severity of asthma and 20 being extremely severe asthma. |
| Secondary | Spirometry Measurements: Forced Expiratory Volume in 1 Second (FEV1) % Predicted, Treatment Steps 2-5:Omalizumab vs. Placebo | 90 Day outcome period | FEV1 is air volume exhaled in 1 second during spirometry. Asthma severity classification for trial: mild--pre-bronchodilator FEV1 ≥ 80% predicted requiring no/ low-moderate dose of inhaled glucocorticoids; moderate--pre-bronchodilator FEV1 \<80% predicted requiring no/ low-moderate dose of inhaled glucocorticoids; severe--requiring high-dose inhaled glucocorticoids with/without continuous/near continuous oral glucocorticoids, or uncontrolled despite treatment. FEV1 percent of predicted value is FEV1 converted to a percentage of normal, based on height, weight, and race. |
| Secondary | Spirometry Measurements: Forced Expiratory Volume in 1 Second (FEV1) % Predicted , Treatment Steps 2-4: Omalizumab vs. ICS | 90 Day outcome period | FEV1 is air volume exhaled in 1 second during spirometry. Asthma severity classification for trial: mild--pre-bronchodilator FEV1 ≥ 80% predicted requiring no/ low-moderate dose of inhaled glucocorticoids; moderate--pre-bronchodilator FEV1 \<80% predicted requiring no/ low-moderate dose of inhaled glucocorticoids; severe--requiring high-dose inhaled glucocorticoids with/without continuous/near continuous oral glucocorticoids, or uncontrolled despite treatment. FEV1 percent of predicted value is FEV1 converted to a percentage of normal, based on height, weight, and race. |
| Secondary | Spirometry Measurements: FEV1:FVCx100, Treatment Steps 2-5: Omalizumab vs. Placebo | 90 Day outcome period | The FEV1 (forced expiratory volume 1))/ FVC (forced vital capacity) ratio is used to evaluate airways obstructions since pure restrictive ventilatory defects cause an equal reduction in the FEV1 and the FVC. An FEV1/FVC ratio below 80% indicates airflow obstruction. Normal FEV1/FVC: 8 - 19 years of age=85%. |

| Secondary | Asthma Control Test Scores: Asthma Control Test (ACT), Treatment Steps 2-5: Omalizumab vs. Placebo | 90 Day outcome period | Outcome measure description: The Asthma Control Test (ACT) is a validated tool to assess asthma control (over the last 4 weeks) in patients ≥12 yrs old. It is comprised of 5 questions assessing symptoms, use of rescue medications, and the impact of asthma on everyday functioning. All questions are scored on a 5-point Likert scale (higher score indicating better control). Total scores can range from 5-25. A score of ≤19 is indicative of not well-controlled asthma. The minimally important difference is 3 points. |
