NCT06472310 | RECRUITING | Severe Asthma

Clinical and demOgRaphic Features of Patients With Uncontrolled Severe Asthma in Russia (CORSAR)
Sponsor:

AstraZeneca

Brief Summary:

This study is an observational multicenter cross-sectional study. Planned study population consists of 5 000 adult patients with uncontrolled SA receiving treatment according to standard of care (except biologics). Planned number of study site is 50 outpatient centers with experience of uncontrolled SA treatment in about 50 regions of Russia (in order to describe characteristics of patients with uncontrolled SA in different regions in the most comprehensive way). 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.

Condition or disease

Severe Asthma

Detailed Description:

There are limited epidemiological data of the patients with uncontrolled severe asthma in Russia since there is no unified system for regular monitoring of patients with severe asthma in the country. 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 severe asthma in particular. Previously reported observational registries are International Severe Asthma Registry (ISAR) and Russian Severe Asthma Registry (RSAR), both studies included patients regardless of whether patients received biological agents or not. The percentage of patients receiving biologics in these studies was 25.4% and 10.6% respectively. 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 SA 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 SA not receiving biologic therapy. Trial will have cross-sectional design and will include 1 visit 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 100 patients will be recruited. The total size of study population will be 5 000 patients.

Accepts Healthy Volunteers:
Criteria
Inclusion Criteria
  • 1. Age ≥ 18 years at the time of inclusion;
  • 2. Signed and dated written informed consent in accordance with ICH GCP and local law prior to inclusion in the study;
  • 3. Patients with diagnosis of uncontrolled SA (Asthma Control Questionnaire-5 (ACQ-5) score \> 1,5) established no less than 52 weeks prior to inclusion; Severe asthma is defined as asthma, that is controlled due to treatment with ICS in medium or high doses plus LABA and/or ALP, and/or LAMA, and/or systemic corticosteroids (sCS), and/or immunobiological therapy, while attempts to reduce the volume of therapy lead to a loss of symptom control, or asthma remains uncontrolled despite this treatment. Such therapy should be carried out at least 3 months before inclusion.
  • Uncontrolled asthma is defined as ACQ-5\>1.5.
  • 4. Patients with the availability of at least 52 weeks of follow-up data (prior to inclusion) in the medical records.
Exclusion Criteria
  • 1. Patients receiving any biological therapy currently or within 52 weeks prior to inclusion;
  • 2. Presence of chronic obstructive pulmonary disease (COPD) or idiopathic pulmonary fibrosis (ILF) currently or in the anamnesis;
  • 3. The participation in any clinical study currently or within 52 weeks prior to inclusion;
  • 4. An acute or chronic disease that, as deemed by Investigator, limits the ability of patients to participate in this study or could influence the interpretation of the results.
