A Comparison of Sputum Between People with COPD and Healthy Controls

What we are studying

The purpose of this study is to see the amount of MMP9 present in subjects with COPD (chronic obstructive pulmonary disease) and subjects that do not have COPD. The results will help to determine the approach for future studies involving the MMP9 and the drug GS-5745, an MMP9 inhibitor. This is a translational study. Translational study means that we will be collecting information from procedures and tests. Being in this study does not require you to take any experimental medication. For the Visit 1 this visit can last up to 2 days and can require you to visit the clinic 1 or 2 times. If you participate in the Optional Visit 2, you will be required to return to the clinic 4 to 14 days after your first visit. The Optional visit can last up to 2 days and can require you to visit the clinic 1 or 2 times.
