Observational Study on Clinical and Demographic Characteristics of Adults With Uncontrolled Severe Asthma Across Russia Not Receiving Biological Therapy

What this Trial Is About

Researchers are conducting an observational multicenter cross-sectional study involving 5,000 adult patients in Russia with uncontrolled severe asthma SA who are receiving standard care treatments except biologics. The study aims to describe the characteristics of these patients across about 50 outpatient centers in 50 regions of Russia, addressing the lack of unified data on severe asthma epidemiology, complications, comorbidities, and treatment patterns in the country. Participants will have a single study visit where demographic and clinical data will be collected without any additional interventions or changes to their routine care. The study will gather information on treatment patterns, including the use of oral corticosteroids and various medication classes, and analyze clinical and demographic features such as age at diagnosis, gender distribution, body mass index, lifestyle factors, and presence of comorbidities. During the study, researchers will review medical records and follow-up data from the prior 52 weeks to assess treatment changes, exacerbations, healthcare resource use, and lung function parameters. No extra diagnostic or therapeutic procedures will be performed beyond standard practice. The study will run from June 2024 to June 2027, aiming to provide detailed epidemiological insights into uncontrolled severe asthma in the Russian adult population.
