About this trial
The main aim of the study to describe the characteristics of participants with asthma across the spectrum of disease severity, including sociodemographic and clinical characteristics, treatment and disease burden, biomarkers, and both disease-specific and generic health-related quality of life.
The study consists of two parts: a cross-sectional study, and a prospective follow-up evaluate changes in disease trajectories in participants with asthma.

Primary outcomes
Part 1: Descriptive Characterization of Participants With Asthma Across the Spectrum of Severities
Descriptive Statistical Analyses may include sociodemographic and clinical characteristics, comorbidities, exacerbation history, medication burden, biomarkers and lung function.
Part 1: ACQ-5 Scores to Evaluate Characteristics of Participants With Asthma
ACQ-5 is a 5-question survey. The five ACQ-5 questions are scored on a 6-point scale (0 = good control, 6 = poor control), and the overall score is the mean of the five responses. Participant's scores are then classified into three prescribed groups as having well-controlled asthma (score ≤ 0.75); partially controlled asthma (score 0.75-1.5), or not well controlled asthma (score \>1.5). A change in ACQ-5 score of 0.5 is considered the minimal clinically important difference (MCID)
Part 1: Mini-Asthma Quality of Life Questionnaire (Mini-AQLQ) Scores to Evaluate Characteristics of Participants With Asthma
The Asthma Quality of Life Questionnaire (AQLQ) includes 32 items, The mini-AQLQ is a reduced version of the AQLQ which includes 15 items. The questions correspond to 4 dimensions of health: symptoms (5 items), limitation of usual activities (4 items), emotional function (3 items) and environmental stimuli (3 items). The response options for each item are on an equidistant scale of 7 points, where 1 corresponds to the maximum disability and 7 to the absence of disability. Higher scores indicating better quality of life (less impairment) and lower scores indicating worse quality of life (greater impairment).
Part 1: Physician Global Assessment of Asthma Severity and Symptom Control
Asthma severity, asthma control, and comorbidity will be assessed using three global impression of severity items: Physician Global Impression of Severity (PhGIS) - asthma severity. PhGIS - asthma control, and PhGIS - comorbidity.
Secondary outcomes
Part 1: Physician-Reported Outcomes to Characterize Physician Perspectives
The treatment preferences for participant profiles, an assessment of perceived disease burden on participants, an evaluation of barriers to optimal treatment, and treatment adherence and persistence will be collected from the main treating physician.
