Real-world, 52-week Prospective Study to Capture the Reasons for Switch to Triple Combination Therapy, Assess the Clinical and Patient Reported Outcomes in Adults With Moderate to Severe Chronic Obstructive Pulmonary Disease (COPD) Treated With Trixeo Aerosphere™ in Routine Care Settings in Greece

Chronic obstructive pulmonary disease (COPD) is a debilitating and progressive respiratory condition characterized by irreversible airflow limitation. The overall 5-year survival for COPD patients is 56-92%, depending on disease severity. Considering the recent introduction of the Budesonide, Glycopyrronium bromide and Formoterol fumarate Metered-Dose Inhaler (BGF MDI) in COPD therapeutic arsenal as well as the increasingly important role of real-world (RW) data in health care decisions, as it bridges gaps not addressed by randomized clinical trials, there is a need for RW evidence studies that can serve as inputs for Health Technology Assessment (HTA) submissions. In view of this need, this study is designed to generate RW evidence on the clinical and patient-reported outcomes of treatment with BGF MDI over a 52-week treatment period in routine care settings in Greece as well as to shed light on the reasons for switching from dual to triple therapy with BGF MDI, aiming at further characterizing the multifactorial aspects of inadequate COPD management that lead physicians to step-up treatment. The study is mainly descriptive in nature and is not planned to reject or affirm any formal statistical hypothesis. This is a single-country, non-interventional, multicenter, 52-week prospective cohort study, mainly based on primary data collection, which will include adult patients with moderate to severe COPD newly prescribed maintenance treatment with BGF MDI in routine care settings of Greece. This study design has been selected on the basis that such studies essentially, through collecting data generated in the course of routine clinical care about management practices and their outcomes from both the physician and patient perspective, help to bridge the knowledge gap between clinical research in controlled randomized settings and daily clinical practice. In line with the purely observational and non-interventional nature of the study, no changes to the current standard of care will be required and all aspects of treatment and clinical management of patients will be in accordance with local clinical practice and at the discretion of the participating physicians. The conduct of this study will adhere to the applicable national regulatory requirements governing the conduct of such type of clinical research. In addition, the study has been designed and will be conducted and reported in accordance with the ethical principles laid down in the Declaration of Helsinki, the Guidelines for Good Pharmacoepidemiology Practice (GPP) of the International Society for Pharmacoepidemiology, the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines where applicable, the European Union (EU) General Data Protection Regulation (GDPR), and the local rules and regulations. Patients will have been prescribed BGF MDI (Trixeo Aerosphere™) prior to informed consent (IC) obtainment and will be treated according to the local prescribing information (Summary of Product Characteristics \[SmPC\]) of the study medication and routine medical practice in terms of visit frequency and type of assessments performed. The assignment of the patient to this therapeutic strategy is not decided in advance by the study protocol but falls within current practice and the prescription of BGF MDI is clearly separated from the physician's decision to include the patient in the current study. In addition, every medical decision including the course of treatment will reflect exclusively the decision of the treating physician in a routine clinical situation according to the product's SmPC. Follow-up visit frequency will be determined by the treating physician, however study-related data will be collected at study enrollment and at 12, 24, 36, and 52-week data collection timepoints post-index (i.e., after BGF MDI treatment initiation) with an allowable time window of ±2 weeks for each data collection timepoint. Data collection at the aforementioned timepoints will be performed in the context of on-site routine visits at the private practices/hospital clinics. In addition, a telephone contact will take place at 4 (±1) weeks post-index for the sole purpose of administering COPD Assessment Test (CAT) by phone interview with the patient. Any visits/contacts occurring at other times not pre-planned in the context of the study will not be captured for the purposes of this study, except for safety-related information, exacerbation data, information on BGF MDI and concomitant COPD-related treatments, that will be collected on a continuous basis. Data collection at all indicated timepoints will be performed in the context of on-site routine visits at the private practices/hospital clinics. There are no dose regimens or diagnostic procedures pre-defined within this study plan. Participation in this observational, real-life study and its documentation procedure will not affect the routine treatment situation in any way.


Eligibility Criteria:
Inclusion Criteria:

* Male or female outpatients aged 40 to 80 years (inclusive) at the time of BGF MDI initiation.
* COPD diagnosis for at least 12 months before BGF MDI initiation in accordance with the definition by the Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2022 Report, as assessed per physician's routine practice or as documented in the patient's chart.
* Patients who have been prescribed but not yet initiated treatment with Budesonide Glycopyrronium bromide Formoterol fumarate pressurized Metered Dose Inhaler (BGF MDI) according to the Summary of Product Characteristics (SmPC) and local market reimbursement criteria. Prescription of BGF MDI must have occurred prior to signed Informed Consent (IC) and the decision to prescribe this therapy must by clearly separated from the physician's decision to include the patient in the current study.
* Spirometry-determined moderate to severe disease defined as post-bronchodilator (post-BD) Forced Expiratory Volume in 1 Second (FEV1)/Forced vital capacity (FVC) ratio \<0.70 and FEV1 \<80% predicted normal value based on most recent spirometry performed within the 3-month period prior to BGF MDI initiation.
* Current or former conventional cigarette smokers with a history of at least 10 pack-years of smoking.
* Patients must be able and willing to read and to comprehend written instructions, and to comprehend and complete the questionnaires required by the protocol.
* Patients must provide a written IC prior to inclusion to the study.

Exclusion Criteria:

* COPD due to documented α-1 antitrypsin deficiency.
* Subjects with current diagnosis of active tuberculosis, lung cancer or lung metastasis, significant bronchiectasis, sarcoidosis, pulmonary fibrosis, pulmonary hypertension, interstitial lung diseases or other active clinically significant pulmonary diseases.
* Subjects with other uncontrolled disease.
* Recent (≤3 months) major cardiac or pulmonary event (for example myocardial infarction, pulmonary embolism).
* Respiratory tract infection \[including, among others, Coronavirus Disease 2019 (COVID-19)\] that has not resolved ≤30 days prior to BGF MDI initiation.
* Requirement of long term (at least 15 hours daily) oxygen therapy.
* Current or recent (≤4 weeks prior to BGF MDI initiation) long-term chronic maintenance use of systemic corticosteroids or antibiotic treatment for any reason other than COPD.
* Current or recent (≤4 weeks prior to BGF MDI initiation) participation in the acute phase of a Pulmonary Rehabilitation Program.
* Currently pregnant (or intention to become pregnant), breastfeeding or lactating women.
