Brief Summary
The purpose of this study is to examine the role of a well-known and well-tolerated antibiotic, doxycycline, in the treatment of cystic fibrosis patients who are hospitalized. This antibiotic does not effectively treat the bacteria in airways of cystic fibrosis patients, but may reduce the activity of inflammatory molecules in the disease.

Limitations and Caveats
Although the study has a relatively large number of subjects, this was a single center trial. In addition, it is possible that the protein readouts are mediated by modulating the dysregulated protease activity in the airway.
