Now what

Savara shared a clinical update with investors a few days ago that was very upbeat. The company stated that two patients who have a specific bacterial infection associated with cystic fibrosis used its inhalable granulocyte-macrophage colony stimulating factor (GM-CSF) and showed meaningful clinical improvement. In fact, a pulmonologist from the Mayo Clinic even went so far as to call the results "remarkable" and noted that the two patients showed "meaningful improvements in weight gain and lung function." 

Savara is currently enrolling patients in a phase 2 study and expects to have topline results in the first half of 2019.

Overall, the vote of confidence from Wall Street and upbeat clinical results make Savara an intriguing clinical-stage biotech to watch.
