Reduction in Rate of Asthma Exacerbations
Query!
Assessment method [1]
0
0
Asthma exacerbation was defined as new or increased asthma symptoms (wheezing, coughing, dyspnea, chest tightness, and/or nighttime awakenings due to these symptoms) that result 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.
Adjusted rates for the overall mITT population (all participants that received at least one dose of study drug) were estimated using Poisson regression and adjusted for blood eosinophil level at the first visit, the number of asthma exacerbations requiring systemic corticosteroids in the 12 months prior to study entry, the total daily ICS dose at the first visit, and geographic region, with patient time at risk used as an offset term.

Achievement in Improvement in Standardized Asthma Quality-of-Life Questionnaire (AQLQ(S)) Score
Query!
Assessment method [3]
0
0
The AQLQ measures the functional problems (physical, emotional, social, and occupational) most troublesome to adults (17-70 years) with asthma. There are 32 questions in 4 domains - symptoms, activity limitation, emotional function, and environmental stimuli - scored on a 7 point scale, with 7= no impairment and 1= severely impaired. For this study, improvement achievement was defined as an increase of at least 0.5 points from baseline to week 54.
Adjusted rates are reported.

Absolute Change in Patient-Reported Daytime Asthma Symptom Severity as Measured by the Asthma Daily Symptom Diary (ADSD)

Assessment method [6]
0
0
The ADSD is a 6-item daily measure of asthma symptom severity that assesses three core categories of asthma symptoms: breathing symptoms, chest symptoms, and cough. Symptoms are rated at their worst using an 11-point numeric rating scale ranging from 0 (no symptoms) to 10 (the worst symptoms imaginable).
Adjusted means are reported.

Percentage of Participants With Adverse Events
Query!
Assessment method [7]
0
0
An adverse event is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events.

Summary
Brief summary
This is a Phase IIb, randomized, placebo-controlled, double-blind, multicenter, multi-arm study which will evaluate efficacy, safety, and pharmacokinetic of MSTT1041A compared with placebo as add-on therapy in participants with severe, uncontrolled asthma who are receiving medium- or high-dose inhaled corticosteroid (ICS) therapy and at least one of the following additional controller medications: long-acting beta-agonists (LABA), leukotriene modifier (LTM), long-acting muscarinic antagonist (LAMA), or long-acting theophylline preparation. The total duration of this study for each participant is approximately 70 weeks including screening, run-in, treatment, and follow-up.
