Triple Therapy in Chronic Obstructive Pulmonary Disease (COPD) Participants
- Conditions
- Pulmonary Disease, Chronic Obstructive
- Interventions
- Other: prospective observational cohort study
- Registration Number
- NCT04657211
- Lead Sponsor
- GlaxoSmithKline
- Brief Summary
TETRIS is a multi-center, prospective observational cohort study. It will include participants with COPD who are on an existing combined treatment of long-acting muscarinic antagonist (LAMA), long-acting beta 2 agonists (LABA) and inhaled corticosteroids (ICS).
- Detailed Description
COPD is a disabling respiratory disease characterized by airflow obstruction and associated symptoms, including breathing difficulties caused by shortness of breath and wheezing, airway hyperactivity, chronic cough, sputum production, exercise intolerance, and poor quality of life. In accordance with the GOLD (Global Initiative for Chronic Obstructive Lung Disease) recommendations, it is important to assess the characteristics and treatment patterns of participants prior to triple therapy initiation, in order to determine adherence to these guidelines and understand how participants progress to triple therapy. Despite a clearly defined guidance from GOLD treatment recommendations for the initiation and maintenance of triple therapy, treatment changes in Germany, including de-escalation, are often seen in treatment reality. This study is intended to gain a better understanding of what influences the treatment decision of German physicians in primary and secondary care under real life conditions, to elicit the reasons for treatment changes and to describe long-term outcomes with participants initiated on triple therapy over a period of two years. This study will also describe the temporal dynamics of treatment pattern and to unravel potentially complex participant's journeys in different German regions and also to identify and follow-up a variety of 'treatable traits' in COPD participants, which when modified may lead to improved health outcomes.

- Target Recruitment
- 1213
- Participant is at least 18 years of age at the time of signing the informed consent.
- Participant is on a SITT or MITT for treatment of an obstructive respiratory disease for a period of 6 to 18 weeks prior enrolment with a combination of inhaled LAMA, LABA and ICS either on a triple maintenance treatment or an intermediate triple therapy regime (ICS "on/off" or LAMA "on/off").
- Inclusion criteria for Group A- (treatment by settled general practitioners): Participants are treated according to a physicians diagnosis of COPD.
- Inclusion criteria for Group B and C- (treatment by settled pulmonologists or treatment by outpatient lung centers): Participants have a confirmed physician's diagnosis (diagnosis based on spirometry or body plethysmography) of COPD.
- Participants need to give and be capable of giving signed informed consent form (ICF).
- Participant has a diagnosis of pure asthma, without clinical features of COPD.
- Participant has a current diagnosis of lung cancer or lung metastasis.
- Participant has a current primary diagnosis of diffuse pan-bronchiolitis, or a primary diagnosis of bronchiectasis or pulmonary fibrosis or cystic fibrosis or other significant respiratory disorders.
- Participant is currently enrolled or has participated in a study within the last 90 days before signing of consent involving investigational study treatment intervention. If, while enrolled in the present study, the participant enrolls in another study involving investigational study treatment intervention, he/she will be withdrawn from the present study.
- Recent (<= months) major cardiac or pulmonary event (for example myocardial infarction, pulmonary embolism).

- Arm && Interventions
Group Intervention Description Group A prospective observational cohort study Participants will receive treatment from settled general practitioners (GPs) (GPs, primary care, practitioner/registered doctor). Group B prospective observational cohort study Participants will receive treatment from settled pulmonologists (specialists, primary or secondary care). Group C prospective observational cohort study Participants will receive treatment at outpatient lung centers (clinics, ambulances, acute care centers).
- Primary Outcome Measures
Name Time Method Percentage of participants with COPD who continuously receive triple therapy Up to 24 months Participants with COPD who continuously receive triple therapy will be evaluated.
The participant should be on a single inhaler triple therapy (SITT) or multiple inhaler triple therapy (MITT) for treatment of an obstructive respiratory disease for a period of 6 to 18 weeks prior enrolment with a combination of inhaled LAMA, LABA and ICS either on a triple maintenance treatment or an intermediate triple therapy regime (ICS "on/off" or LAMA "on/off").
- Secondary Outcome Measures
Name Time Method Percentage of COPD participants with different profiles who are on triple therapy (LAMA/LABA/ICS) Visit 1 at Day 1 Percentage of participants with different profiles will be summarized which will include asthma at the age of less than (\<) 40 years, peripheral blood eosinophils (EOS) of \<100 cells per microliter (/µl), 100-200 cells/µl, 200-300 cells/µl and more than (\>) 300 cells/µl, physician's diagnosis of COPD by site localization and physician´s group, participants who meet GOLD definition of COPD, and medications received by COPD participants (including Oral Corticosteroids \[OCS\]), split by physician group and site localization.
Number of participants who initiated on triple therapy by different clinical outcomes Up to 24 months Clinical outcomes will include mean annual rate of moderate and/or severe exacerbations, mean annual rate of hospitalizations due to severe exacerbations, change of lung function parameters, change of COPD symptoms, change in health-related quality of life (HRQoL), clinically important deterioration, time to first event, time to first moderate or severe exacerbation, time to first hospitalization/intensive care unit admission, and time to death.
Number of participants who initiated triple therapy as per decision of German physicians Up to 24 months Participants who initiated triple therapy as per decision of German physicians with pre-specified reason to initiate triple therapy will be summarized.
Percentage of COPD participants with combined treatable traits Up to 24 months Percentage of participants with combined treatable traits will be summarized which will include smoking and non-smoking history when initiating triple therapy; forced expiratory volume in 1 second (FEV1)/ forced vital capacity (FVC) ratio \<0.7; at least one event of unstable COPD, cold requiring antibiotics or exacerbation; COPD Assessment Test(CAT) score less than or equal to (\>=)10; peripheral blood EOS count \>=100 cells/µl; emphysematous versus chronic bronchitis phenotype; and physical activity level in participants over a 24 months observation period.
Number of COPD participants by healthcare resource utilization and the ongoing sequence of care events Up to 24 months Participant's journey will be summarized which will include the ongoing sequence of care events which a participant follows from the point of access into the health system, continuing towards diagnosis and care and ending in outpatient care.
Number of participants with pneumonia and cardiovascular events as measure of safety Up to 24 months Number of participants with pneumonia and cardiovascular events will be evaluated along with benefit-harm profiles for the triple therapy.
Percentage of participants with at least one switch from triple therapy to LAMA/LABA or to ICS/LABA Up to 24 months Participants with at least one switch from triple therapy to LAMA/LABA or to ICS/LABA will be evaluated.
