MultIceNtre Non-intERVentional Study for Efficacy,Safety Evaluation of BREZTRI in Pts With COPD in RussiA

Completed

• Conditions: Chronic Obstructive Pulmonary Disease

• Registration Number: NCT06422676
• Lead Sponsor: AstraZeneca

Brief Summary

This is a retrospective-prospective, non-interventional, multi-centre study that will be conducted in routine clinical settings in Russia. Eligible patients with moderate to severe COPD routinely treated with BREZTRI will be observed according to routine clinical practice for up to 24 weeks.

Detailed Description

Chronic obstructive pulmonary disease (COPD) is a disease characterized by persistent airflow limitation that is usually progresses and is a consequence of a chronic inflammatory response of the respiratory pathways and lung tissue to the effects of inhaled harmful particles or gases. Exacerbations and comorbid conditions are an integral part of the disease and contribute significantly to the clinical picture and prognosis \[1\].

Patient-reported outcomes (both symptom-based and health-related quality of life-specific) are essential to evaluate symptoms, impact of symptoms on activities of daily living, and treatment response in COPD patients \[12\].

There is a need to evaluate the patient-reported outcomes during a triple therapy with budesonide + glycopyrronium bromide + formoterol (Breztri) in a real-life clinical practice. The aim of the study is to evaluate clinical and patient-reported outcomes of treatment with BREZTRI through effectiveness measures assessed pre- and post-treatment initiation and safety monitoring. The study results will be interpreted in the context of an open label, single arm study design where multiple factors, in addition to the new treatment, may contribute to the treatment effect.

Study & Design

• Study Type: OBSERVATIONAL
• Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
Change in COPD Assessment Test (CAT) score	24 weeks	Change from baseline to 24 weeks in the CAT score. Minimum value - "0", maximum value - "5". Higher scores mean worse outcome.

Secondary Outcome Measures

Name	Time	Method
Change in COPD Assessment Test (CAT) score	12 weeks	Change from baseline to 12 weeks in the CAT score. Minimum value - "0", maximum value - "5". Higher scores mean worse outcome.
Change in the Treatment Satisfaction Questionnaire for Medication (TSQM) score	24 weeks	Change from baseline to 24 weeks in the TSQM score. Minimum score - "1", maximum score - "7". Higher scores mean better outcome.
PGI-C - any improvement	24 weeks of treatment	Percent of patients with response (any category better than "no change") at the PGI-C after 24 weeks of treatment
Change in FEV1	24 weeks	Change from baseline to 24 weeks in FEV1
MCID >= 2	24 weeks of treatment	• Percent of responders using the CAT who achieved MCID (minimal clinically important difference) = 2 or more points after 24 weeks of treatment
>= 20 points at MARS	24 weeks	Percent of patients who are high adherent to therapy (who received 20 or more points at MARS) during 24 weeks;
To describe treatment safety by AE (adverse events) monitoring	AEs will be collected from the day when the informed consent has been signed (Visit 0) until the time last visit (Visit 2- 24 (+2) weeks after index date) has occurred	to monitor AE frequency
PGI-S - change from baseline	after 24 weeks of treatment	• Percent of patients with change from baseline (before Breztri treatment start) in the severity of general COPD symptoms at the PGI-S after 24 weeks of treatment
Treatment safety by AE monitoring	AEs will be collected from the day when the informed consent has been signed (Visit 0) until the time last visit (Visit 2- 24 (+2) weeks after index date) has occurred	to collect information on treatment discontinuation due to AE
