What is a Clinical Trial?
A clinical trial is a health-related research study in human beings that follows a pre-defined protocol. Interventional studies aim to answer specific questions about new therapies or new ways of using known treatments, while observational studies are those in which patients are observed and their outcomes are measured by the investigators. Carefully conducted clinical trials are the safest and most efficient way to identify treatments that are effective and safe.
There are several benefits to participating in a clinical trial. Participants have the opportunity to play an active role in their own health care, gain access to new investigational treatments before they are made widely available, and help others by contributing to the advancement of medical science through research.
The welfare of participants in clinical trials is carefully protected by the IRB (Institutional Review Board) and the Ethics Committee, each of which reviews all aspects of a clinical trial both before the investigator is able to enroll participants and throughout the trial.
We are asking you to participate in a research study to determine if we can detect changes in enzymes in the blood that may influence lung function decline in COPD (Chronic Obstructive Pulmonary Disease), in particular after COPD exacerbations. The procedures of the study include: pulmonary function test (breathing test), a short questionnaire, blood and urine sample. The duration of the study is 2 years: First visit and Second visit 2 years later.
We are asking you to participate in a research study to determine if we can detect minor lung injury that we cannot currently measure with available tests. This injury can occur when somebody is smoking for a long time or when somebody has COPD (Chronic Obstructive Pulmonary Disease). We want to compare the results of people who have never smoked, people who are current smokers and people who have known COPD. The procedures of the study include: lung imaging (SPECT/CT), pulmonary function test (breathing test), blood and urine sample.
