2 DOSAGE AND ADMINISTRATION For oral inhalation use only. ( 2.1 ) Use ARIKAYCE vials only with the Lamira Nebulizer System. ( 2.1 ) Pre-treatment with inhaled bronchodilator should be considered in patients with a history of hyperreactive airway disease. ( 2.1 ) The recommended dosage in adults is once daily oral inhalation of the contents of one 590 mg/8.4 mL ARIKAYCE vial. ( 2.2 ) 2.1 Important Administration Instructions ARIKAYCE is for oral inhalation use only. Administer by nebulization only with the Lamira ® Nebulizer System. Refer to the Instructions for Use for full administration information on use of ARIKAYCE with the Lamira Nebulizer System. Instruct patients using a bronchodilator ('reliever') to first use the bronchodilator following the bronchodilator leaflet for use information before using ARIKAYCE. Pre-treatment with short-acting selective beta-2 agonists should be considered for patients with known hyperreactive airway disease, chronic obstructive pulmonary disease, asthma, or bronchospasm [see Warnings and Precautions (5.3) ] . 2.2 Recommended Dosage The recommended dosage of ARIKAYCE in adults is once daily inhalation of the contents of one 590 mg/8.4 mL ARIKAYCE vial (590 mg of amikacin) using the Lamira Nebulizer System [see Clinical Studies (14) ] . Administer ARIKAYCE with the Lamira Nebulizer System only. ARIKAYCE should be at room temperature before use. Prior to opening, shake the ARIKAYCE vial well for at least 10 to 15 seconds until the contents appear uniform and well mixed. The ARIKAYCE vial is opened by flipping up the plastic top of the vial then pulling downward to loosen the metal ring. The metal ring and the rubber stopper should be removed carefully. The contents of the ARIKAYCE vial can then be poured into the medication reservoir of the nebulizer handset. If a daily dose of ARIKAYCE is missed, administer the next dose the next day. Do NOT double the dose to make up for the missed dose.

6 ADVERSE REACTIONS The following clinically significant adverse reactions are described in greater detail in other sections of labeling: Hypersensitivity pneumonitis [see Boxed Warning and Warnings and Precautions (5.1) ] Hemoptysis [see Boxed Warning and Warnings and Precautions (5.2) ] Bronchospasm [see Boxed Warning and Warnings and Precautions (5.3) ] Exacerbation of Underlying Pulmonary Disease [see Boxed Warning and Warnings and Precautions (5.4) ] Anaphylaxis and Hypersensitivity Reactions [see Warnings and Precautions (5.5) ] Ototoxicity [see Warnings and Precautions (5.6) ] Nephrotoxicity [see Warnings and Precautions (5.7) ] Neuromuscular Blockade [see Warnings and Precautions (5.8) ] Most common adverse reactions (incidence ≥10% and higher than control) in the patients with refractory MAC lung disease were: dysphonia, cough, bronchospasm, hemoptysis, musculoskeletal pain, upper airway irritation, ototoxicity, fatigue/asthenia, exacerbation of underlying pulmonary disease, diarrhea, nausea, and headache.

Overview of Clinical Trials for Safety Evaluation Within the refractory NTM clinical program, 404 patients that participated in three clinical trials were treated with ARIKAYCE at the dose of 590 mg/day (median duration of exposure to ARIKAYCE was 236.5 days). Trial 1 (NCT#02344004) was an open-label, randomized (2:1), multi-center Phase 3 trial in patients with refractory Mycobacterium avium complex (MAC) lung disease. Patients were randomized to either 8 months of ARIKAYCE plus a background regimen (n=223) or background regimen alone (n=112). Trial 2 (NCT#02628600) was a single-arm extension of Trial 1 for refractory MAC lung disease patients that failed to achieve negative sputum cultures after 6 months of treatment or had a relapse or recurrence by Month 6 from either study arm of Trial 1. A total of 163 patients (n=90 from the prior background regimen alone arm of Trial 1, and n=73 from the prior ARIKAYCE plus background regimen arm in Trial 1) participated in the trial. Trial 3 (NCT#01315236) was a double-blind, randomized, placebo-controlled Phase 2 study in patients with refractory nontuberculous mycobacterial (NTM) lung disease caused by MAC and Mycobacterium abscessus . Patients were randomized to either ARIKAYCE plus background regimen (N=44) or an inhaled diluted empty liposome placebo plus background regimen (N=45) for 84 days. Across all clinical trials of patients with and without refractory NTM lung infection, 818 patients were exposed to multiple doses of ARIKAYCE. Adverse Reactions Leading to Treatment Discontinuation In the three NTM studies, there was a higher incidence of premature discontinuation of ARIKAYCE. In Trial 1, 34.5% discontinued ARIKAYCE prematurely; most were due to adverse reactions (18.8%) and withdrawal by subject (9.9%). In the comparator arm, 10.7% of subjects discontinued their background regimen, with 0.9% due to adverse reactions and 5.4% due to withdrawal by subject. In Trial 2 (the single-arm extension of Trial 1), 37.8% of patients starting on ARIKAYCE discontinued prematurely with 24.4% discontinuing due to adverse reactions. In Trial 3, all 9 (20.5%) premature discontinuations occurred in the ARIKAYCE plus background regimen-treated patients and there were no premature discontinuations in the placebo plus background regimen arm. Serious Adverse Reactions in Trials 1 and 3 In Trial 1, 19.7% of patients treated with ARIKAYCE plus background regimen reported SAR as compared to 16.1% of patients treated with background regimen alone. In addition, in Trial 1 [2 to 1 randomization, ARIKAYCE plus background regimen versus background regimen alone], there were 80 hospitalizations in 41 patients (18.4%) treated with ARIKAYCE plus background regimen compared to 29 hospitalizations in 15 patients (13.4%) treated with background regimen alone. The most common SARs and reasons for hospitalization in the ARIKAYCE plus background regimen arm were related to exacerbation of underlying pulmonary disease and lower respiratory tract infections, such as pneumonia. In Trial 3, 18.2% of patients treated with ARIKAYCE plus background regimen reported SARs compared to 8.9% of patients treated with background regimen plus inhaled placebo. Common Adverse Reactions The incidence of adverse reactions in Trial 1 are displayed in Table 1. Only those adverse reactions with a rate of at least 5% in the ARIKAYCE plus background regimen group and greater than the background regimen alone group, are shown.

Because these adverse reactions are reported voluntarily from a population of unknown size, precise estimates of frequency cannot be made and a causal relationship to drug exposure cannot be established. Gastrointestinal disorders: dysphagia, glossitis, glossodynia, salivary hypersecretion, stomatitis, abdominal pain, abdominal distension Immune system disorders: hypersensitivity, anaphylaxis, pharyngeal swelling [see Warnings and Precautions (5.5) ] Respiratory, thoracic, and mediastinal disorders: nasal dryness, rhinorrhea, sneezing, nasal congestion

12.3 Pharmacokinetics Sputum Concentrations Following once daily inhalation of 590 mg ARIKAYCE in Mycobacterium avium complex (MAC) patients, sputum concentrations at 1 to 4 hours post-inhalation were 1720, 884, and 1300 mcg/g at 1, 3, and 6 months, respectively. High variability in amikacin concentrations were observed (CV% >100%). After 48 to 72 hours post-inhalation, amikacin sputum concentrations decreased to approximately 5% of those at 1 to 4 hours post-inhalation. Serum Concentrations Following 3 months of once daily inhalation of 590 mg ARIKAYCE in MAC patients, the mean serum AUC 0-24 was 23.5 mcg*hr/mL (range: 8.0 to 46.5 mcg*hr/mL; n=12) and the mean serum C max was 2.8 mcg/mL (range: 1.0 to 4.4 µg/mL; n=12). The maximum C max and AUC 0-24 were below the mean C max of approximately 76 mcg/mL and AUC 0-24 of 154 mcg*hr/mL observed for intravenous administration of amikacin sulfate for injection at the approved dosage of 15 mg/kg once daily in healthy adults. Absorption The bioavailability of ARIKAYCE is expected to vary primarily from individual differences in nebulizer efficiency and airway pathology. Distribution The protein binding of amikacin in serum is ≤ 10%. Elimination Following inhalation of ARIKAYCE in MAC patients, the apparent serum half-life of amikacin ranged from approximately 5.9 to 19.5 hrs. Metabolism Amikacin does not undergo appreciable metabolism. Excretion Systemically absorbed amikacin following ARIKAYCE administration is eliminated principally via glomerular filtration. On average, 7.42% (ranging from 0.72 to 22.60%; n=14) of the total ARIKAYCE dose was excreted in urine as unchanged drug compared to 94% following intravenous administration of amikacin sulfate for injection. Unabsorbed amikacin, following ARIKAYCE inhalation, is probably eliminated primarily by cellular turnover and expectoration. Drug Interaction Studies No clinical drug interaction studies have been conducted with ARIKAYCE [see Drug Interactions (7) ].
