Clinical& Demographic Profiles of patIents With unControllEd Asthma in Russia: Multi-center oBsErvational ReGistry Study

This study is a multi-centre, non-interventional, observational, ambispective registry. Planned study population consists of 10 000 adult patients with uncontrolled asthma receiving treatment according to standard of care (except biologics). Planned number of study site is 70 outpatient centers with experience of uncontrolled asthma treatment in about 50 regions of Russia (in order to describe characteristics of patients with uncontrolled asthma in different regions in the most comprehensive way).

There are limited epidemiological data of the patients with uncontrolled asthma in Russia. The systematic information about complications and comorbidities, about the treatment approaches and their effectiveness in the Russian population is also absent.

The observational registry is really important to describe the epidemiological characteristics of the disease and to analyse the clinical characteristics of the various subgroups of patients. This is an excellent starting point to be able to investigate the characteristics of the disease in detail.

The Russian Federation consists of 85 regions with a total population of more than 145 million people. The regions differ in ethnic composition, age, gender, climate, ecology, economic level, prevalence of asthma in general and uncontrolled asthma in particular.

Thus, there is a need to perform a large-scale observational registry in regions of the country with a sufficient size of population to obtain information on uncontrolled asthma epidemiology, clinical and demographic characteristics, to describe main clinical outcomes and evaluate existing associations between observed treatment patterns and clinical outcomes in real clinical practice in patients with uncontrolled asthma not receiving biologic therapy.

Trial will have ambispective design and will include 2 visits for obtaining the patient's demographic and clinical data. To allow wide data coverage the study will involve at least 50 regions of Russian Federation; in each region 200 patients will be recruited. The total size of study population will be 10 000 patients.

All data will be collected during 2 visits carried out according to routine clinical practice for observation and treatment of patients with uncontrolled asthma. At visit 1, baseline data of 52 weeks prior to inclusion will be collected by physician based on the patient's medical records and interview during the visit. Visit 2 (final visit) will be conducted after 3 months in order to collect follow-up data which coincides with the recommended dates. Information on changes in the treatment of uncontrolled asthma and on clinical outcomes will be collected.

This non-interventional study does not imply any intervention into a routine clinical practice, and does not provide for any diagnostic and therapeutic procedures other than those used in routine practice.
