* Number of Subjects with Grade 3 or Higher Abnormalities in Clinical Laboratory Values * Number of Subjects with Grade 3 or Higher Hematology Laboratory Value Abnormalities * Number of Subjects with Grade 3 or Higher Chemistry Laboratory Value Abnormalities

Number of Subjects with a \>15% in Decline in Forced Expiratory Volume in 1 Second (FEV1) From Predose to Postdose

Respiratory rate was recorded at every visit as per standard practice at each investigational site.

Pulse rate (after at least 5-minute rest) was recorded at every visit as per standard practice at each investigational site.

Sitting blood pressure was recorded at every visit as per standard practice at each investigational site.

Sitting blood pressure was recorded at every visit as per standard practice at each investigational site.

Body temperature was recorded at every visit as per standard practice at each investigational site.

Change in oxygen saturation as measured with pulse oximetry was performed via finger probes placed on the extremity opposite arterial lines and noninvasive blood pressure monitoring devices so that pulsatile flow was not interrupted.

Sputum was cultured for quantitative microbiological evaluation of Pa and Burkholderia species in designated regional central microbiology laboratories. A standard microbiology protocol was used for Pa culture and identification for each morphologically distinct Pa phenotype. Although planned in the Statistical Analysis Plan (SAP), MICs of amikacin Burkholderia species were not determined due to the small number of isolates with Burkholderia. In addition, susceptibility testing of isolates of Pa and Burkholderia species against a panel of commonly used antipseudomonal antibiotics was planned but was not performed. The results of the following analyses for Pa isolates are presented. * Frequency of MIC of Amikacin * Frequency of MIC of Tobramycin MIC50: lowest concentration of the antibiotic at which 50 % of the isolates were inhibited.

Hearing was evaluated using air conduction \[AC\]. Bone conduction was required if the AC testing demonstrated a decrease of \>20 decibels \[dB\]. Hearing loss was categorized using Common Terminology Criteria for Adverse Events as follows: GRADE 1 (best): Adults \[A\] on a Monitoring Program \[MP\]: Threshold shift of 15-25 dB; Pediatric \[P\]: Threshold shift \>20 dB at 8 kilohertz (kHz). GRADE 2: \[A\] on a MP: Threshold shift of \>25 dB; \[A\] not enrolled in MP: hearing loss; hearing aid/intervention not indicated; \[P\]: Threshold shift \>20 dB at 4 kHz and above. GRADE 3: \[A\] enrolled in MP: Threshold shift of \>25 dB; therapeutic intervention indicated; \[A\]: Not enrolled in MP: hearing aid/intervention; \[P\]: therapeutic intervention, including hearing aids: Threshold shift \>20 dB at 3 kHz and above; additional speech-language related services. GRADE 4 (worst): \[A\]: Profound bilateral hearing loss; non-serviceable hearing; \[P\]: cochlear implant \& additional speech-language related services.

* Common Terminology Criteria for Adverse Events (CTCAE) Grade 1: \> ULN-1.5 × ULN * CTCAE Grade 2: \> 1.5 × ULN to 3.0 x ULN

The endpoint used the 7-step semi-quantitative scale (SQS) for mycobacterial culture reporting in both solid and liquid growth media, with step 1 = culture negative in both solid and liquid media, step 2 = growth in liquid medium only, 3 = solid medium positive, 4 = 50 to 100 colonies in solid medium \& growth in liquid, 5 = \>100 to 200 colonies in solid medium \& growth in liquid, 6 = \>200 to 500 colonies in solid medium \& growth in liquid, 7 = \>500 colonies in solid medium \& growth in liquid. Full scale range is 1 (best score) to 7 (worst score). The change in step measures the growth at Day 84 compared to the growth at Baseline. The negative values represent reduction in colony growth.
