(QPIT) or homozygosity for ΔF508 genetic mutation or heterozygosity for two well characterized mutations.

- Ability to perform pulmonary function tests.

- FEV1 ≥ 40% predicted at Visit 1 (Screening).

Exclusion Criteria:

(Screening) and within 6 half-lives of the investigational drug.

two years.

- Current daily continuous oxygen supplementation or requirement for more than 2 L/min

at night.

- Known local or systemic hypersensitivity to monobactam antibiotics.

- History of lung transplantation.

- A chest radiograph at Visit 1 (Screening) or within the previous 90 days of

Screening, with abnormalities indicating a significant acute finding (eg, lobar infiltrate and atelectasis, pneumothorax, or pleural effusion).

- Abnormal renal or hepatic function or serum chemistry at Visit 1 (Screening):

- AST, ALT > 2. 5 times upper limit of normal range.

- Creatinine > 1. 5 times upper limit of normal range.
