Detailed Description
This was a long-term, open-label, multi-cycle extension study for patients in the Phase 3 study TR02-108 and TR02-109 who had successfully completed the 168-day study period and met study safety criteria. As this was a safety and tolerability long-term extension study, no sample size calculations were performed. All patients who completed TR02-108, were compliant with the study protocol, and did not meet any of the criteria listed for study discontinuation (safety reasons or non-compliance) were able to participate in this open-label study.
The end of study visit for TR02-108 was to serve as the baseline study visit (Day 1) for TR02-110 if the patient had signed the informed consent at least 4 days prior to the end of study visit and met all safety criteria for TR02-110. If the end of study visit was not used as the baseline visit, a separate baseline visit (Day 1) was to be performed within 14 days of completing TR02-108.
Patients were to receive a delivered dose of 590 mg LAI QD via a PARI Investigational eFlow® Nebulizer System (eFlow®) for 28 days followed by a 28-day off-treatment period. This cycle (28 days on treatment, 28 days off treatment) was to be repeated for up to 12 cycles. The study was implemented as 2 consecutive extension periods, each consisting of 48 weeks (approximately 12 months). Patients were re-consented for the second extension period at the completion of the first extension period. The total study period was up to 96 weeks (approximately 2 years).
During the first 28 days of treatment, patients were evaluated at the study site bi-weekly for safety, tolerability and efficacy. Thereafter, for the duration of the study, patients were evaluated at the study site on the first and last days of dosing during the on-treatment periods. During the study, starting with the off-treatment period of Cycle 1, patients were contacted by telephone once during every 28-day period to assess safety. A final site visit occurred 28 days after last dose of LAI. Arikace™, Arikayce™,Liposomal Amikacin for Inhalation (LAI), and Amikacin Liposome Inhalation Suspension (ALIS) may be used interchangeably throughout this study and other studies evaluating amikacin liposome inhalation suspension.

Time Frame: Day 1, Day 169, Day 337, Day 505 and Day 672
|
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.
MIC50: lowest concentration of the antibiotic at which 50 % of the isolates were inhibited. |

Hearing was evaluated using air conduction [AC].

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.
