Beskrivelse
Inclusion Criteria:
- Age 18 years or older.
- Documentation of CF diagnosis.
- Have a pre-bronchodilator FEV1 ≥ 40% of predicted at Visit 1 and have a Visit 2 pre-investigational product FEV1 that is ≥ 40% of predicted and within ± 15% of the Visit 1 result.
- Deemed by the Investigator to be a suitable candidate for serial collection of expectorated sputum.
Exclusion Criteria:
- Had a pulmonary exacerbation during the 4 weeks before screening (Visit 1) which required the initiation of new antibiotic treatment
- Have a pulmonary exacerbation during the screening period (between Visit 1 and Visit 2) which requires the initiation of new antibiotic treatment
- FEV1 < 0.59 liters at the screening visit
- Respiratory insufficiency with continuous supplemental oxygen therapy, or carbon dioxide retention
- Elevated aspartate transaminase (AST) or alanine aminotransferase (ALT) that is ≥ 3 times the upper limit of normal for age and gender
- Smoking during the past 6 months
- Lung surgery during the past 2 years
- Positive culture for Burkholderia cepacia or mycobacterium during the past two years.
- Active allergic bronchopulmonary aspergillosis
- Pre-treatment sputum collection at Visit 1 or Visit 2 (Randomization) characterized by problems such as inadequate sputum volume or quality.
- Known selective Immunoglobulin A (IgA) deficiency with known antibody against IgA (anti-IgA antibody).
- History of anaphylaxis or severe systemic response to any plasma-derived alpha1-proteinase inhibitor preparation or other blood product(s), or to polysorbates.
- Use of chronic oral steroids during the study. Note: Inhaled corticosteroids that had been administered for at least 4 weeks prior to Visit 1 were permissible during the study.
- Use of chronic, high dose ibuprofen therapy within 3 weeks of screening and at anytime during the study.
- Chronic maintenance therapy with systemic antibiotics within 3 weeks of screening and through last dose of investigational product.
- Use of leukotriene synthesis inhibitor (zileuton) or leukotriene receptor antagonists (montelukast, zafirlukast) within 3 weeks of screening and at anytime during the study.
- Use of roflumilast within 3 weeks of screening and at any time during the study.
- Initiation of a new chronic medication or dosage change of a chronic medication for treatment of cystic fibrosis (example: Kalydeco™ [ivacaftor]) within 3 weeks of screening (Visit 1).
