An Ambispective Observational Multicenter Registry of Patients With Uncontrolled Asthma in Russia

What this Trial Is About

Researchers are studying uncontrolled asthma in adults across Russia to better understand its characteristics and treatment patterns. This large-scale observational registry will include 9,000 patients from 70 outpatient centers in about 50 regions, focusing on those not receiving biologic therapy. The study aims to describe demographic and clinical features, capture complications and comorbidities, and evaluate routine therapies used in real practice. The study has an ambispective design with two main visits. At the first visit, physicians will collect baseline data from the past 52 weeks using medical records and patient interviews. The second visit, conducted 12 weeks later, will gather follow-up information on treatment changes and clinical outcomes. A subgroup of 500 patients using fixed-dose combination budesonide/salbutamol will have an additional third visit 12 weeks after the second to collect further data. Participants will undergo routine clinical assessments during 2 to 3 visits following standard practice. Researchers will examine demographic and clinical data, blood and sputum eosinophil counts, total IgE levels, asthma control status, lung function tests, exacerbation rates, and healthcare resource use. Safety monitoring aligns with routine care, and the study does not involve any experimental treatments or procedures. Total participation spans approximately 24 weeks for those in the extended follow-up group.
