Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to characterize bacterial diversity and richness in the sputum of cystic fibrosis patients treated with every-other-month TOBIâ„¢ Podhalerâ„¢ and continuous alternating therapy with TOBIâ„¢ Podhaler and colistimethate (Colistin).
