Description

11 DESCRIPTION The active ingredient in ARIKAYCE (amikacin liposome inhalation suspension) is amikacin sulfate USP, an aminoglycoside antibacterial. Its chemical name is D-Streptamine, O -3-amino-3-deoxy-α-D-glucopyranosyl-(1→6)- O -[6-amino-6-deoxy-α-D-glucopyranosyl-(1→4)]- N 1 -(4-amino-2-hydroxy-1-oxobutyl)-2-deoxy-, ( S )-, sulfate (1:2) salt with a chemical formula of C 22 H 43 N 5 O 13 ∙2H 2 SO 4 with a molecular weight of 781.76. Its structural formula is: ARIKAYCE is a white milky suspension consisting of amikacin sulfate encapsulated in liposomes and is supplied in a unit-dose 10 mL clear glass vial containing amikacin 590 mg/8.4 mL (equivalent to amikacin sulfate 788 mg/8.4 mL) as a sterile aqueous liposomal suspension for oral inhalation. ARIKAYCE consists of amikacin sulfate encapsulated in liposomes at a targeted concentration of 70 mg amikacin/mL with the pH range of 6.1 to 7.1 and lipid to amikacin weight ratio in the range of 0.60 to 0.79. The inactive ingredients are cholesterol, dipalmitoylphosphatidylcholine (DPPC), sodium chloride, sodium hydroxide (for pH adjustment), and water for injection. ARIKAYCE is administered only using a Lamira Nebulizer System [see Dosage and Administration (2.1) ]. Like all other nebulized treatments, the amount delivered to the lungs will depend upon patient factors. Under standardized in vitro testing per USP<1601> adult breathing pattern (500 mL tidal volume, 15 breaths per minute, and inhalation: exhalation ratio of 1:1), the mean delivered dose from the mouthpiece was approximately 312 mg of amikacin sulfate (53% of label claim). The mass median aerodynamic diameter (MMAD) of the nebulized aerosol droplets is about 4.7 µm (4.1 – 5.3 µm) as determined using the Next Generation Impactor (NGI) method. A percentage of the amikacin in the liposome is released by the nebulization process, thus nebulized ARIKAYCE delivers a combination of free and liposomal amikacin. Chemical Structure

Dosage and Administration

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.

Side Effects (Adverse Reactions)

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. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Insmed Incorporated at 1-844-4-INSMED or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. 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...

Pregnancy and Breastfeeding

8.1 Pregnancy Risk Summary There are no data on ARIKAYCE use in pregnant women to evaluate for any drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. Although systemic absorption of amikacin following oral inhalation is expected to be low [see Clinical Pharmacology (12.3) ], systemic exposure to aminoglycoside antibacterial drugs, including ARIKAYCE, may be associated with total, irreversible, bilateral congenital deafness when administered to pregnant women [see Warnings and Precautions (5.9) ] . Advise pregnant women of the potential risk to a fetus. Animal reproductive toxicology studies have not been conducted with inhaled amikacin. Subcutaneous administration of amikacin to pregnant rats (up to 100 mg/kg/day) and mice (up to 400 mg/kg/day) during organogenesis was not associated with fetal malformations. Ototoxicity was not adequately evaluated in offspring in animal studies. The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. Data Animal Data No animal reproductive toxicology studies have been conducted with ARIKAYCE or non-liposomal amikacin administered by inhalation. Amikacin was subcutaneously administered to pregnant rats (Gestation Days 8-14) and mice (Gestation Days 7-13) at doses of 25, 100, or 400 mg/kg to assess developmental toxicity. These doses did not cause fetal visceral or skeletal malformations in mice. The high dose was excessively maternally toxic in rats (nephrotoxicity and mortality were observed), precluding the evaluation of offspring at this dose. Fetal malformations were not observed at the low or mid dose in rats. Postnatal development of the rats and mice exposed to these...

Overdosage

10 OVERDOSAGE Adverse reactions specifically associated with overdose of ARIKAYCE have not been identified. Acute toxicity should be treated with immediate withdrawal of ARIKAYCE, and baseline tests of renal function should be undertaken. Hemodialysis may be helpful in removing amikacin from the body. In all cases of suspected overdosage, physicians should contact the Regional Poison Control Center for information about effective treatment. In the case of any overdosage, the possibility of drug interactions with alterations in drug disposition should be considered.
