Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Time to First Composite Asthma Exacerbations (CompEX) Event	CompEX is defined as time from randomization to first asthma exacerbation or diary worsening during the treatment period.; Asthma exacerbation was defined as new or increased asthma symptoms (wheezing, coughing, dyspnea, chest tightness, and/or nighttime awakenings due to these symptoms) that resulted in one or both of the following: Hospitalization or emergency department visit with administration of systemic corticosteroid treatment; Treatment with systemic corticosteroids for at least 3 days, or a long-acting depot corticosteroid preparation with a therapeutic effectiveness of at least 3 days. Diary worsening is based on the occurrence of prespecified changes in the following six parameters: morning peak expiratory flow rate (PEFR), evening PEFR, morning symptom score, evening symptom score, morning short-acting rescue therapy use, and evening short-acting rescue therapy use. Hazard ratio was used for the analysis.	Randomization [Week 2] to end of treatment (EOT) [Week 50]
Secondary	Rate of Asthma Exacerbations	The number of asthma exacerbations per year was reported for this outcome measure. Asthma exacerbation was defined as new or increased asthma symptoms (wheezing, coughing, dyspnea, chest tightness, and/or nighttime awakenings due to these symptoms) that resulted in one or both of the following: Hospitalization or emergency department visit with administration of systemic corticosteroid treatment; Treatment with systemic corticosteroids for at least 3 days, or a long-acting depot corticosteroid preparation with a therapeutic effectiveness of at least 3 days. Poisson regression was used for the analysis.	Randomization [Week 2] to Week 50
Secondary	Time to First Asthma Exacerbation	The time from randomization to first asthma exacerbation was measured. Asthma exacerbation was defined as new or increased asthma symptoms (wheezing, coughing, dyspnea, chest tightness, and/or nighttime awakenings due to these symptoms) that resulted in one or both of the following: Hospitalization or emergency department visit with administration of systemic corticosteroid treatment; Treatment with systemic corticosteroids for at least 3 days, or a long-acting depot corticosteroid preparation with a therapeutic effectiveness of at least 3 days. Cox regression was used for the analysis.	Randomization [Week 2] to Week 50
Secondary	Absolute Change From Randomization in Pre-Bronchodilator Forced Expiratory Volume in 1 Second (FEV1) at Week 50	FEV1 is calculated as the volume of air forcibly exhaled in one second as measured by a spirometer. Estimates are based on a mixed model for repeated measures (MMRM) analysis with an unstructured covariance matrix. The model used the absolute change pre-bronchodilator FEV1 as the response variable and included terms for treatment arm, study visit, treatment arm by study visit interaction, baseline FEV1 as well as its interaction with study visit, in addition to the stratification factors: blood eosinophil level at visit 1 (<150, >=150 to <=300, >300 cells/microliter (uL)), number of asthma exacerbations requiring the use of systemic corticosteroids within the 12 months prior to the study entry (1 or >=2 events), and geographic region.	Randomization [Week 2] to Week 50
Secondary	Relative Percent Change From Randomization in Pre-Bronchodilator FEV1 at Week 50	FEV1 was the volume of air exhaled in the first second of a forced exhalation as measured by spirometer. Measurements were performed before use of bronchodilator. Estimates are based on a mixed model for repeated measures (MMRM) analysis with an unstructured covariance matrix. The model used the relative change pre-bronchodilator FEV1 as the response variable and included terms for treatment arm, study visit, treatment arm by study visit interaction, baseline FEV1 as well as its interaction with study visit, in addition to the stratification factors: blood eosinophil level at visit 1 (<150, >=150 to <=300, >300 cells/uL), number of asthma exacerbations requiring the use of systemic corticosteroids within the 12 months prior to the study entry (1 or >=2 events), and geographic region. Relative change (%) in FEV1 = (absolute change in FEV1 / baseline FEV1) x 100.	Randomization [Week 2] to Week 50
Secondary	Absolute Change From Randomization in Fractional Exhaled Nitric Oxide (FeNO) at Week 50	FeNO is a volatile marker of airway inflammation that decreases with inhaled corticosteroid treatment. The measurements recorded were according to standardized procedures by the American Thoracic Society. Estimates are based on a mixed model for repeated measures (MMRM) analysis with an unstructured covariance matrix. The model used the absolute change pre-bronchodilator FeNO as the response variable and included terms for treatment arm, study visit, treatment arm by study visit interaction, baseline FeNO as well as its interaction with study visit, in addition to the stratification factors: blood eosinophil level at visit 1 (<150, >=150 to <=300, >300 cells/uL), number of asthma exacerbations requiring the use of systemic corticosteroids within the 12 months prior to the study entry (1 or >=2 events), and geographic region.	Randomization [Week 2] to Week 50
Secondary	Relative Percent Change From Randomization in FeNO at Week 50	FeNO is a volatile marker of airway inflammation that decreases with inhaled corticosteroid treatment. The measurements recorded were according to standardized procedures by the American Thoracic Society. Relative change (%) in FeNO = (absolute change in FeNO / baseline FeNO) x 100. Estimates are based on a mixed model for repeated measures (MMRM) analysis with an unstructured covariance matrix. The model used the absolute change pre-bronchodilator FeNO as the response variable and included terms for treatment arm, study visit, treatment arm by study visit interaction, baseline FeNO as well as its interaction with study visit, in addition to the stratification factors: blood eosinophil level at visit 1 (<150, >=150 to <=300, >300 cells/uL), number of asthma exacerbations requiring the use of systemic corticosteroids within the 12 months prior to the study entry (1 or >=2 events), and geographic region.	Randomization [Week 2] to Week 50
Secondary	Percentage of Participants With Adverse Events	An adverse event (AE) is any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not considered related to the medicinal (investigational) product.	Up to approximately Week 58
Secondary	Area Under Concentration-Time Curve for the First Dosing Interval (AUClast) of MTPS9579A		Randomization [Week 2] to Week 6
Secondary	Maximum Serum Concentration (Cmax) for the First Dosing Interval of MTPS9579A		2-hour post-dose on Week 2
Secondary	Steady State Cmax of MTPS9579A		2-hour post-dose on Week 14
Secondary	Maximum Time to Serum Concentration (Tmax) of MTPS9579A		Pre-dose and 2-hour post-dose on Week 2
Secondary	Trough Serum Concentration (Ctrough) Accumulation Ratio of MTPS9579A	The accumulation ratio is calculated by taking the individual ratio of the Ctrough at Week 14 to the Ctrough at Week 6.	Predose on Weeks 6 and 14
Secondary	Steady State Ctrough of MTPS9579A		Pre-dose on Week 14
Secondary	Percentage of Participants With Anti-Drug Antibodies (ADA) to MTPS9579A	Treatment Emergent ADA is (a) negative or missing baseline ADA result(s) and at least one positive post-baseline ADA result, OR (b) positive ADA result at baseline and one or more post-baseline titer results that are at least 0.60 titer unit (t.u.) greater than the baseline titer result.	Pre-dose Week 54
