About this study
Official title: Clinical Implementation and Outcomes Evaluation of Blood-Based Biomarkers for Chronic Obstructive Pulmonary Disease Management
Chronic Obstructive Pulmonary Disease (COPD) is a progressive disease that is characterized by loss of lung function, leading to breathlessness, poor quality of life, loss in productivity, and increased mortality. The World Health Organization estimates that COPD will be the third leading cause of death worldwide by 2020, accounting for more than 7 million deaths annually. COPD patients frequently experience 'lung attacks', during which breathlessness, coughing, and sputum production dramatically increase, leading to urgent office visits, emergency admissions and hospitalizations. Lung attacks reduce patient quality of life and cost the Canadian health care system nearly $4 billion dollars each year in direct and indirect costs. Lung attacks can be effectively managed if they are identified and treated early, but symptoms of a lung attack often overlap with those of other common conditions such as heart failure, pneumonia and even influenza. Because there are no tests that can separate lung attacks from these conditions, doctors struggle to accurately diagnose lung attacks at an early stage when drugs are most effective. This can lead to a delayed or even incorrect diagnosis and inappropriate treatment. This research will address this critical need. Our goal is to improve COPD patient care by developing new blood tests that will help identify patients who are in the early stages of a lung attack. Doctors will be able to use these tests to treat lung attacks at earlier stages than is currently possible. These blood tests will enable doctors to personalize management of COPD to meet the needs of the individual patient.
Hypothesis: New biomarker blood tests can be used to better identify and manage patients with COPD.
Read the detailed description
An acute exacerbation of COPD (AECOPD) is defined as an acute event characterized by a worsening of the patient's respiratory symptoms that is beyond normal day-to-day variations and leads to a change in medication (in most cases to antibiotics and/or oral corticosteroids). In most cases of AECOPD, patients experience a gradual crescendo-like increase in shortness of breath, cough and purulent sputum production over days to weeks. At their peak, patients may experience extreme shortness of breath (sometimes described as "breathless paralysis") and uncontrollable paroxysms of cough and purulent sputum production. AECOPDs are complex physiological events. In 70-80% of cases, AECOPDs are precipitated by bacterial or viral respiratory tract infections. However, most patients who develop acute symptoms (e.g., runny nose, cough or fever) do not progress to AECOPDs and experience spontaneous resolution of their symptoms. Furthermore, many patients with COPD who do harbour pathogenic organisms in their airways do not develop AECOPD symptoms. Thus, other factors, including the host inflammatory response, likely play a role in the pathogenesis of AECOPDs. Prompt recognition and treatment of AECOPD during this prodromal period can abrogate full blown attacks. Thus by identifying and treating AECOPDs early on (in physicians' offices), emergency visits, hospitalizations, and even deaths can be significantly reduced. However, this is not easy as symptoms of AECOPD (especially early in their course) are non-specific and can easily be confused with other ailments such as heart failure, allergies, or even upper respiratory tract infections. Since there are no biochemical tests that clinicians can order to objectively confirm AECOPD, AECOPD can be missed entirely or misdiagnosed, leading to delayed treatments or in some cases to the wrong treatment, which may result in devastating consequences including respiratory failure, hospitalizations or even death. Once patients are in the full blown attack stage of AECOPD, treatments are only modestly helpful in relieving symptoms and hospitalization is often required to resolve them. The median duration of hospitalization for AECOPD in Canada is 10 days, followed by an average of 3 months of convalescence. Unfortunately, in most cases, full recovery is never achieved and patients continue to experience rapid decline in lung and physical function (compared to patients not hospitalized for AECOPD). The 3 year mortality rate following hospitalization is 50%, and hospitalizations and emergency visits are avoidable with earlier detection, diagnosis and treatment of AECOPD. Indeed, COPD is the leading cause of preventable hospitalization in Canada. However, without a simple blood test that primary care physicians (PCPs) can order in their offices, earlier diagnosis will not be feasible.
The primary objective of this study is to identify blood biomarkers that can diagnose AECOPD.
Following informed consent, blood samples will be collected from patients who are admitted for an exacerbation at day 1, 3 and 7 of their hospitalization and then at 30 days and 90 days post-hospitalization. Sputum samples will also be collected on the day of admission for AECOPD etiologic phenotyping. All patients receive standard anti-exacerbation care in hospital, including systemic corticosteroids and antibiotics and are followed both in and out of hospital by a transition team consisting of a nurse, physiotherapist and respiratory therapist with special expertise in COPD care.
Following informed consent of non-exacerbating patients, a blood sample will be collected which will be used as a comparison to the exacerbating patient samples.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Exacerbation | Patients experiencing acute exacerbation of COPD. | |
| Non-Exacerbation | COPD patients not experiencing acute exacerbation of COPD. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Exacerbation
Hospitalized and non-hospitalized exacerbations occurring within 1 year of hospital discharge from index hospitalization will be recorded. Non-hospitalized exacerbations will be defined by treatment with prednisone plus/minus antibiotics. Hospitalized exacerbations will be defined as a diagnosis of acute exacerbation of COPD at admission or at presentation to emergency.
Measured: Within 1 year

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Chronic Obstructive Pulmonary Disease (COPD) is a progressive disease that is characterized by loss of lung function, leading to breathlessness, poor quality of life, loss in productivity, and increased mortality. The World Health Organization estimates that COPD will be the third leading cause of death worldwide by 2020, accounting for more than 7 million deaths annually. COPD patients frequently experience 'lung attacks', during which breathlessness, coughing, and sputum production dramatically increase, leading to urgent office visits, emergency admissions and hospitalizations.

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Exacerbation (time frame: Within 1 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02050022, which also lists 17 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Apr 2021.
