What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change From Baseline to End of the Treatment Period of Forced Expiratory Volume in 1 Second (FEV1), Expressed as Percentage of Predicted Normal
Time Frame: Day 0 (baseline), Week 4
|
Pulmonary function measurements were performed by using a self-calibrated computer-operated pneumotochographic spirometer at all clinic visits.
Because this study included both adults and children and lung volume is an age-dependent variable, reference normal FEV1 values for children were different than the reference normal values used with adult participants.
Three measurements were collected and the greatest FEV1 value was recorded.
|
Day 0 (baseline), Week 4
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change From Baseline to End of Weeks 2, 4, and 8 of Forced Expiratory Volume in 1 Second (FEV1), Expressed as Percentage of Predicted Normal
Time Frame: Day 0 (baseline), Week 2, Week 4, Week 8
|
Pulmonary function measurements were performed by using a self-calibrated computer-operated pneumotochographic spirometer at all clinic visits.
Because this study included both adults and children and lung volume is an age-dependent variable, reference normal FEV1 values for children were different than the reference normal values used with adult participants.
Three measurements were collected and the greatest FEV1 value was recorded.
Observed values are summarized (without last observation carry forward).
|
Day 0 (baseline), Week 2, Week 4, Week 8
|
Change From Baseline to End of Weeks 2, 4, and 8 of Absolute Forced Expiratory Volume in 1 Second (FEV1)
Time Frame: Day 0 (baseline), Week 2, Week 4, Week 8
|
Pulmonary function measurements were performed by using a self-calibrated computer-operated pneumotochographic spirometer at all clinic visits.
Three measurements were collected and the greatest FEV1 value was recorded.
Observed values are summarized (without last observation carry forward).
|
Day 0 (baseline), Week 2, Week 4, Week 8
|
Change From Baseline at End of Weeks 2, 4, and 8 of Forced Vital Capacity (FVC) Expressed as Percentage of Predicted Normal
Time Frame: Day 0 (baseline), Week 2, Week 4, Week 8
|
FVC is the amount of air which can be forcibly exhaled from the lungs after taking the deepest breath possible.
It is measured via spirometry.
Because this study included both adults and children and lung volume is an age-dependent variable, reference normal FVC values for children were different than the reference normal values used with adult participants.
|
Day 0 (baseline), Week 2, Week 4, Week 8
|
Change From Baseline to End of Weeks 2, 4, and 8 of Absolute Forced Vital Capacity (FVC)
Time Frame: Day 0 (baseline), Week 2, Week 4, Week 8
|
FVC is the amount of air which can be forcibly exhaled from the lungs after taking the deepest breath possible.
It is measured via spirometry.
|
Day 0 (baseline), Week 2, Week 4, Week 8
|
Change From Baseline to End of Weeks 2, 4, and 8 of Forced Expiratory Flow at 25-75% of Vital Capacity (FEF 25-75%), Expressed as Percentage of Predicted Normal
Time Frame: Day 0 (baseline), Week 2, Week 4, Week 8
|
Difference in the forced expiratory flow rate in mid-exhalation as a percent of predicted to standard values measured from baseline to weeks 2 (treated), 4 (treated), and 8 (untreated).
Because this study included both adults and children and lung volume is an age-dependent variable, reference normal FEF 25-75% values for children were different than the reference normal values used with adult participants.
|
Day 0 (baseline), Week 2, Week 4, Week 8
|
Change From Baseline to End of Weeks 2, 4, and 8 of Forced Expiratory Flow at 25-75% of Vital Capacity (FEF 25-75%)

|
Difference in the forced expiratory flow rate in mid-exhalation measured from baseline to weeks 2 (treated), 4 (treated), and 8 (untreated).
|
Day 0 (baseline), Week 2, Week 4, Week 8
|
Change From Baseline to End of Weeks 4 and 8 in Pseudomonas Aeruginosa Log10 Bacterial Load in Sputum
Time Frame: Day -10 to -1 (baseline), Week 4, Week 8
|
If a participant had more than one Pseudomonas aeruginosa (PA) morphotype at a given visit, and therefore more than one bacterial load value, then the bacterial load value corresponding to the highest tobramycin minimal inhibitory concentration (MIC) value regardless of the PA morphotype was used.
If the tobramycin MIC value was the same for different PA morphotypes, then the bacterial load value corresponding to morphotype 1 (mucoid colony) was used.
If morphotype 1 was not available, bacterial load value corresponding to morphotype 2 (dry colony) was used.
|
Day -10 to -1 (baseline), Week 4, Week 8
|
Minimal Inhibitory Concentration Inhibiting Growth of 50% (MIC50) of Pseudomonas Aeruginosa
Time Frame: Week 4, Week 8
|
MIC50 is the concentration of tobramycin required to inhibit 50% of Pseudomonas aeruginosa. MIC values were calculated for three different Pseudomonas aeruginosa (PA) strains:
Overall MIC50 values are reported. If a participant has more than one PA morphotype at a given visit, then the highest tobramycin MIC value was used, regardless of PA morphotype. If a participant has more than one available result for each morphotype then the highest tobramycin MIC value was used. If the tobramycin MIC values are equal then the MIC value for the isolate with the highest bacterial load value was used. |
Week 4, Week 8
|
Minimal Inhibitory Concentration Inhibiting Growth of 90% (MIC90) of Pseudomonas Aeruginosa
Time Frame: Week 4, Week 8
|
MIC90 is the concentration of tobramycin required to inhibit 90% of Pseudomonas aeruginosa. MIC values were calculated for three different Pseudomonas aeruginosa (PA) strains:
Overall MIC90 values are reported. If a participant has more than one PA morphotype at a given visit, then the highest tobramycin MIC value was used, regardless of PA morphotype. If a participant has more than one available result for each morphotype then the highest tobramycin MIC value was used. If the tobramycin MIC values are equal then the MIC value for the isolate with the highest bacterial load value was used. |
Week 4, Week 8
|
Microbiological Outcome Summary by Visit
Time Frame: Day -10 to -1 (screening), Weeks 4 and 8
|
Microbiological outcomes are derived considering all P. aeruginosa (PA) morphotypes together. Week 4 and Week 8 microbiological outcomes:
Superinfection supersedes eradication. Persistence for P. aeruginosa supersedes superinfection. Re-infection for P. aeruginosa supersedes superinfection. |
Day -10 to -1 (screening), Weeks 4 and 8
|
Change From Baseline to End of Weeks 2, 4 and 8 in Body Weight
Time Frame: Day 0 (baseline), Weeks 2, 4 and 8
|
Body weight was measured at all study visits as part of the physical examination.
|
Day 0 (baseline), Weeks 2, 4 and 8
|
Change From Baseline to End of Weeks 2, 4 and 8 in Body Mass Index (BMI)
Time Frame: Day 0 (baseline), Weeks 2, 4 and 8

Count of Participants With Treatment-Emergent Adverse Events (TEAEs)
Time Frame: Day 0 to Week 8
|
Treatment-Emergent Adverse Events defined as adverse events occurring after the first intake of study treatment (or the same day). The investigator assessed relation to study treatment as a binary question: Reasonable possibility of relatedness or no reasonable possibility of relatedness. The expression "reasonable possibility of relatedness" is meant to convey in general that there are facts (evidence) or arguments meant to suggest a causal relationship. A serious AE results in death, is life-threatening, requires hospitalization or prolongation of existing inpatient hospitalization, results in persistent or significant disability or incapacity, is a congenital anomaly/birth defect or an important medical event. The investigator rates the severity of the AE based on a three point scale: mild, moderate or severe. A severe event prevents any usual routine activity of the participant and causes severe discomfort. |
Day 0 to Week 8
|
Participants With a Hearing Threshold >20 Decibel in at Least One Ear
Time Frame: Day -10 to -1 (screening), Weeks 4 and 8
|
The potential ototoxic effects (hearing loss) of tobramycin were investigated by performing audiometric tests.
Participants with a loss of auditory acuity greater than the 20 decibels auditory threshold are reported.
