Chronic Obstructive Pulmonary Disease is a leading cause of global morbidity and mortality, especially in low- and middle-income countries. Exacerbations accelerate disease progression and increase the risk of death. Recent recommendations from the GOLD report emphasize the diagnosis of COPD and treatment planning based on a combination of lung function metrics, exacerbation history, and patient-reported symptoms. It is recommending the use of triple combination therapy (ICS+LABA+LAMA) such as BREZTRI/TRIXEO as one of the options in Group E patients. While BGF has demonstrated efficacy in controlled clinical trials, real-world evidence is needed to assess its impact on daily patient outcomes and quality of life.
The iCHOROS study is a real-world, international, multicenter, observational study aiming to evaluate changes in clinical and patient-reported outcomes in adults with moderate to severe COPD treated with BGF for 12 months in routine care settings across Latin America, Asia, and the Middle East \& Africa. The study will provide valuable insights into the effectiveness and patient experience of BGF therapy in diverse, real-world populations

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
. Patients with recent (≤3 months) major cardiac or pulmonary events that required hospitalization (e.g., myocardial infarction, pulmonary embolism).
. Patients previously treated with triple fixed-dose combination therapies 12 months before the screening visit or treated with Multiple Inhaled Triple Therapy (MITT) within the last 3 months before the screening visit.
. Patients hospitalized due to COPD exacerbations within the last 30 days prior to enrolment.
. Currently pregnant (or intending to become pregnant), breastfeeding, or lactating women.
. Patients with a current diagnosis of asthma, active tuberculosis, lung cancer or lung metastasis, significant bronchiectasis, sarcoidosis, pulmonary fibrosis, pulmonary hypertension, interstitial lung diseases, or other active clinically significant pulmonary diseases.
. Patients currently participating in a non-interventional observational trial that might, in the investigator's opinion, influence the assessment for the current study or participation in any interventional trial in the last 30 days prior to enrolment.
. Patients with respiratory tract infection (including COVID-19 infection) ) that has not resolved ≤30 days prior to BGF MDI initiation and those exhibiting persistent long-COVID symptoms are excluded from the study.
