Primary Efficacy:

On hundred subjects with CF age >/= 6 years old with chronic Burkholderia infection were randomized to receive 24 weeks of AZLI (ztreonam for inhalation solution) 75 mg or placebo followed by 24 weeks of open label AZLI. Eighty-four subjects continued into the open label phase.
There was no difference between subjects treated with AZLI or placebo in % change in FEV1% predicted (measured by the time-adjusted area under the curve) in the 24-week randomized phase.

Continuous AZLI treatment was safe in CF subjects with Burkholderia. Total adverse event rates were similar in both groups.
