E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To estimate the proportion of subjects free from any strain of P. aeruginosa assessed by sputum / swab culture at Day 29, i.e. after completion of a 28-day treatment period with either TOBI or placebo solution inhaled twice daily. |
|
E.2.2 | Secondary objectives of the trial |
• To assess the safety profile of TOBI inhaled twice daily or placebo throughout the treatment period in subjects in this age group.
• To estimate the proportion of subjects free from any strain of P. aeruginosa assessed by sputum / swab culture 28 days after termination of the 2nd treatment cycle (day 91) with either TOBI inhaled twice daily for 28 days or placebo.
• To estimate the proportion of subjects free from any strain of P. aeruginosa assessed by sputum / swab culture 28 days after termination of treatment with either TOBI inhaled twice daily for 28 days or placebo.
• To assess the pharmacokinetics of TOBI in this age group
• To assess lung function in the subset of subjects able to reliably perform spirometry

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Written informed consent given by the parent/legal guardian on behalf of the subject.
2. Diagnosis of CF by one or more clinical features of CF:
• a documented sweat chloride test of > 60 mEq/L by quantitative pilocarpine iontophoresis
• genotype with two identifiable CF-causing mutations
• a positive newborn screening for CF
3. Male and female subjects aged 3 months to less than 7 years of age at the time of screening.
4. Early lower respiratory tract infection with P. aeruginosa, defined by either of the following:
a. The first time P. aeruginosa isolated
b. P. aeruginosa isolated after at least 1 year of negative cultures (documented with at least two negative cultures during the latter 1-year period, with no positive culture during that period)
5. Positive P. aeruginosa culture isolated from sputum, deep throat swab or nasopharyngeal aspiration specimens collected and tested from routine clinical culture performed at local site laboratory within 1 months prior to randomization
6. Able to comply with all protocol requirements (except spirometry where not applicable)
Clinically stable in the opinion of the investigator
|
|
E.4 | Principal exclusion criteria |
1. Any oral or iv anti-pseudomonal antibiotic treatment within 1 year prior to randomization
2. Serum creatinine above the upper limit of the normal range for age documented from at least one analysis performed at site laboratory within 6 month prior to randomization
3. Known local or systemic hypersensitivity to aminoglycosides or inhaled antibiotics.
4. Signs and symptoms of acute pulmonary disease, e.g., pneumonia, pneumothorax.
5. Administration of any investigational drug within 30 days or 5 half-lives prior to enrollment, whichever is longer.
6. Administration of loop diuretics within 7 days prior to study drug administration.
7. Personal/family history of abnormal hearing
8. Current (continuing, present at screening) or persisting abnormal result from audiology testing (defined as either a unilateral pure-tone audiometry test showing a threshold elevation > 20 dB at any frequency across the frequency range 0.25 kHz to 8 kHz or the absence of emission at the evoked otoacoustic emission test).
9. History of sputum culture, throat swab, or lower respiratory specimen culture yielding Burkholderia cepacia (B. cepacia) within 2 years prior to screening and/or sputum culture yielding B. cepacia at screening.
10. Hemoptysis which is clinically significant based on the subjects age and clinical status within 30 days prior to study drug administration.
11. History of malignancy of any organ system treated or untreated, regardless of whether there is evidence of local recurrence or metastases,
12. Subjects with clinically significant laboratory abnormalities including congenital diseases other than CF (not associated with the study indication) documented from at least one laboratory chemistry and haematology analysis performed within 1 year prior to randomization
13. Subjects with other clinically significant conditions (not associated with the study indication) at screening which might interfere with the assessment of this study
14. Subjects or caregivers with a history of noncompliance to medical regimens and subjects or caregivers who are considered potentially unreliable.
