Who can join

Age: 6 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Males or females aged 6 years and older
• Subjects with CF as diagnosed by one of the following: documented sweat chloride >= 60 mEq/L by quantitative pilocarpine iontophoresis test, or documented sweat sodium >= 60 mmol/L, or 2 well characterized genetic mutations in the Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) gene, or abnormal nasal potential difference with accompanying symptoms characteristic of CF
• Documented PA in an expectorated sputum or throat swab culture within 3 months prior to Visit 1 or at Visit 1
• Subjects must be able to provide written informed consent/assent prior to any study related procedures; parent/guardian must be able to give written informed consent as necessary prior to any study related procedure
• Subjects must have received previous treatment with aerosolized antibiotics without demonstration of drug intolerance
• FEV1 <= 75% predicted at Visit 1
• Ability to perform reproducible pulmonary function tests
• Chest radiograph at Visit 1 without significant acute findings (eg, infiltrates [lobar or diffuse interstitial], pleural effusion, pneumothorax); or chest radiograph or magnetic resonance image (MRI) obtained within the 180 days prior to Visit 1 without acute findings and no significant intercurrent illness; chronic, stable findings (eg, chronic scarring or atelectasis) are allowed

You may not qualify if…

• Current use of oral corticosteroids in doses exceeding the equivalent of 10 mg prednisone a day or 20 mg prednisone every other day
• History of sputum or throat swab culture yielding B. cepacia in the previous 2 years
• Current requirement for daily continuous oxygen supplementation or requirement for more than 2 L/minute at night
• Administration of any investigational drug or device within 28 days of Visit 1 or within 6 half-lives of the investigational drug (whichever is longer)
• Known local or systemic hypersensitivity to monobactam antibiotics
• Known allergies/intolerance to tobramycin
• Inability to tolerate inhalation of a short acting beta agonist
• Changes in or initiation of chronic azithromycin treatment within 28 days prior to Visit 1
• Administration of antipseudomonal antibiotics by inhalation, intravenous or oral routes within the 14 days prior to Randomization/Visit 2
• Changes in antimicrobial, bronchodilator (BD), dornase alfa, or corticosteroid medications within 7 days prior to Visit 1
• Changes in physiotherapy technique or schedule within 7 days prior to Visit 1
• History of lung transplantation
• Abnormal renal or hepatic function or serum chemistry at Visit 1, defined as aspartate aminotransferase (AST), alanine aminotransferase (ALT) > 5 times upper limit of normal range (ULN) or creatinine > 2 times ULN
• Positive pregnancy test at Visit 1; all women of childbearing potential will be tested
• Female of childbearing potential who is lactating or is not (in the opinion of the investigator) practicing an acceptable method of birth control; female subjects who utilize hormonal contraceptives as one of their birth control methods must have used the same method for at least 3 months before study dosing
• Any serious or active medical or psychiatric illness, which in the opinion of the investigator, would interfere with patient treatment, assessment, or compliance with the protocol
