AIRSUPRA

1 INDICATIONS AND USAGE AIRSUPRA is indicated for the as-needed treatment or prevention of bronchoconstriction and to reduce the risk of exacerbations in patients with asthma 18 years of age and older. AIRSUPRA is a combination of albuterol, a beta 2 -adrenergic agonist and budesonide, a corticosteroid, indicated for the as-needed treatment or prevention of bronchoconstriction and to reduce the risk of exacerbations in patients with asthma 18 years of age and older.

2 DOSAGE AND ADMINISTRATION • Recommended Dosage: AIRSUPRA 180 mcg/160 mcg (administered as 2 actuations of albuterol/budesonide 90 mcg/80 mcg) by oral inhalation as needed for asthma symptoms. ( 2.1 ) • Do not take more than 6 doses (12 inhalations) in a 24-hour period. ( 2.1 ) • Prime inhaler prior to first use. Re-prime when inhaler has not been used for more than 7 days, is dropped, or after cleaning. ( 2.2 ) • Discard when the dose counter displays 0. ( 2.3 ) 2.1 Recommended Dosage and Administration The recommended dosage of AIRSUPRA is albuterol 180 mcg and budesonide 160 mcg (administered as 2 actuations of AIRSUPRA [albuterol/budesonide 90 mcg/80 mcg]) as needed for asthma symptoms by oral inhalation. Do not take more than 6 doses (12 inhalations) in a 24-hour period [see Warnings and Precautions (5.4) ] . 2.2 Priming Before Use • Priming AIRSUPRA is essential to ensure appropriate drug content in each actuation. Prime AIRSUPRA before using for the first time. To prime AIRSUPRA, release 4 sprays into the air away from the face, shaking well before each spray. • AIRSUPRA must be re-primed when the inhaler has not been used for more than 7 days, is dropped, or after cleaning. To re-prime AIRSUPRA, release 2 sprays into the air away from the face, shaking well before each spray. 2.3 Dose Counter The canister has an attached dose indicator (also known as puff indicator) which indicates how many inhalations (puffs) remain. The dose indicator pointer will move after every actuation. The pointer will show the number of inhalations remaining in the canister. When nearing the end of the usable inhalations, the color behind the number in the dose indicator display window changes to yellow. AIRSUPRA should be discarded when the pointer reaches zero.

5 WARNINGS AND PRECAUTIONS • If symptoms continue after using AIRSUPRA, this may be a marker of destabilization of asthma and requires reevaluation of treatment. ( 5.1 ) • If paradoxical bronchospasm occurs, discontinue AIRSUPRA immediately and institute alternative therapy. ( 5.2 ) • Cardiovascular effects may occur. Use with caution in patients sensitive to sympathomimetic drugs and patients with cardiovascular disorders. ( 5.3 ) • Excessive use may be fatal. Do not exceed maximum recommended dosage. ( 5.4 ) • Hypersensitivity reactions may occur. Discontinue AIRSUPRA immediately. ( 5.5 ) • Use with caution in patients with convulsive disorders, hyperthyroidism, diabetes mellitus, and ketoacidosis. ( 5.6 ) • Hypokalemia may occur. ( 5.7 ) • Potential worsening of infections (e.g., existing tuberculosis; fungal, bacterial, viral, or parasitic infections; or ocular herpes simplex). Use with caution in patients with these infections. More serious or even fatal course of chickenpox or measles can occur in susceptible patients. ( 5.8 ) • Oropharyngeal candidiasis may occur. Advise patients to rinse mouth with water, if available, without swallowing after use. Monitor patients periodically. ( 5.9 ) • Hypercorticism and adrenal suppression may occur with very high dosages in susceptible individuals. If such changes occur, consider appropriate therapy. ( 5.10 ) • Monitor patients with major risk factors for decreased bone mineral content. ( 5.11 ) • Glaucoma and cataracts may occur. Consider referral to an ophthalmologist in patients who develop ocular symptoms. ( 5.12 ) 5.1 Deterioration of Asthma Asthma may deteriorate acutely over a period of hours or chronically over several days or longer. If the patient continues to experience symptoms after using AIRSUPRA or requires more doses of AIRSUPRA than usual, this may be a marker of destabilization of asthma and requires evaluation of the patient and their treatment regimen. 5.2 Paradoxical Bronchospasm AIRSUPRA can produce paradoxical bronchospasm, which may be life threatening. If paradoxical bronchospasm occurs following dosing with AIRSUPRA, it should be discontinued immediately, and alternative therapy should be instituted. It should be recognized that paradoxical bronchospasm, when associated with inhaled formulations, frequently occurs with the first use of a new canister. 5.3 Cardiovascular Effects AIRSUPRA, like other drugs containing beta 2 -adrenergic agonists, can produce clinically significant cardiovascular effects in some patients as measured by increases in pulse rate, blood pressure, and/or other symptoms. If such effects occur, AIRSUPRA may need to be discontinued. In addition, beta-agonists have been reported to produce electrocardiogram (ECG) changes, such as flattening of the T wave, prolongation of the QTc interval, and ST-segment depression. The clinical significance of these findings is unknown. Therefore, AIRSUPRA, like all sympathomimetic amines, should be used with caution in patients with cardiovascular disorders, especially coronary insufficiency, cardiac arrhythmias, and hypertension. 5.4 Do Not Exceed Recommended Dosage As with other inhaled drugs containing beta-adrenergic agents, AIRSUPRA should not be used more than the maximum daily dose [see Dosage and Administration (2.1) ] , as an overdose may result. Clinically significant cardiovascular effects and fatalities have been reported in association with excessive use of inhaled sympathomimetic drugs. 5.5 Hypersensitivity Reactions, Including Anaphylaxis Hypersensitivity reactions can occur after administration of albuterol sulfate and budesonide, components of AIRSUPRA, as demonstrated by cases of anaphylaxis, angioedema, bronchospasm, oropharyngeal edema, rash, and urticaria. Discontinue AIRSUPRA if such reactions occur [see Contraindications (4) ] . 5.6 Risk of Sympathomimetic Amines with Certain Coexisting Conditions AIRSUPRA, like all therapies containing sympathomimetic amines, should be used wi…

4 CONTRAINDICATIONS AIRSUPRA is contraindicated in patients with a history of hypersensitivity to albuterol, budesonide, or any of the excipients [see Warnings and Precautions (5.5) , Description (11) ] . Hypersensitivity to albuterol, budesonide, or to any of the excipients. ( 4 )

7 DRUG INTERACTIONS No formal drug interaction studies have been performed with AIRSUPRA. • Strong cytochrome P450 3A4 inhibitors (e.g. ritonavir): Use with caution. May cause systemic corticosteroid effects. ( 7.1 ) • Other short-acting bronchodilators: Use judiciously with other short-acting beta agonists. ( 7.2 ) • Beta blockers: May decrease effectiveness of AIRSUPRA and produce severe bronchospasm. When there are no acceptable alternatives to the use of beta-adrenergic-blocking agents, consider cardioselective beta-blockers and use with caution. ( 7.3 ) • Diuretics, or non-potassium-sparing diuretics: May potentiate hypokalemia or ECG changes. Consider monitoring potassium levels with concomitant use. ( 7.4 ) • Digoxin: May decrease serum digoxin levels. Carefully evaluate digoxin levels with concomitant use. ( 7.5 ) • Monoamine oxidase inhibitors (MAOI) and tricyclic antidepressants: Use AIRSUPRA with extreme caution with concomitant use. ( 7.6 ) 7.1 Inhibitors of Cytochrome P450 3A4 The main route of metabolism of corticosteroids, including budesonide, a component of AIRSUPRA, is via cytochrome P450 (CYP) isoenzyme 3A4 (CYP3A4). After oral administration of ketoconazole, a strong inhibitor of CYP3A4, the mean plasma concentration of orally administered budesonide increased. Concomitant administration of a CYP3A4 inhibitor may inhibit the metabolism of, and increase the systemic exposure to, budesonide. Caution should be exercised when considering the co-administration of AIRSUPRA with long-term ketoconazole and other known strong CYP3A4 inhibitors (e.g., ritonavir, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, saquinavir, telithromycin) [see Warnings and Precautions (5.11) ] . 7.2 Use with Other Short-Acting Bronchodilators AIRSUPRA contains the short-acting beta-agonist, albuterol. Therefore, concomitant use of additional beta-agonists with AIRSUPRA should be used judiciously to prevent beta-agonist overdose. 7.3 Beta-Blockers Beta-adrenergic receptor blocking agents not only block the pulmonary effect of beta-agonists, such as albuterol, a component of AIRSUPRA, but may also produce severe bronchospasm in patients with asthma. Therefore, patients with asthma should not normally be treated with beta-blockers. However, under certain circumstances, e.g., as prophylaxis after myocardial infarction, there may be no acceptable alternatives to the use of beta-adrenergic-blocking agents in these patients. In this setting, consider cardioselective beta-blockers, although they should be administered with caution. 7.4 Diuretics The ECG changes and/or hypokalemia which may result from the administration of non-potassium-sparing diuretics (such as loop or thiazide diuretics) can be acutely worsened by beta-agonists, especially when the recommended dose of the beta-agonist is exceeded. Although the clinical significance of these effects is not known, caution is advised in the coadministration of AIRSUPRA with non-potassium-sparing diuretics. Consider monitoring potassium levels. 7.5 Digoxin Mean decreases of 16% and 22% in serum digoxin levels were demonstrated after single-dose intravenous and oral administration of albuterol, respectively, to normal volunteers who had received digoxin for 10 days. The clinical significance of these findings for patients with obstructive airway disease who are receiving albuterol and digoxin on a chronic basis is unclear. Nevertheless, it would be prudent to carefully evaluate the serum digoxin levels in patients who are currently receiving digoxin and AIRSUPRA. 7.6 Monoamine Oxidase Inhibitors or Tricyclic Antidepressants AIRSUPRA should be administered with extreme caution to patients being treated with monoamine oxidase inhibitors or tricyclic antidepressants, or within 2 weeks of discontinuation of such agents, because the action of albuterol on the cardiovascular system may be potentiated.

8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to asthma medications during pregnancy. For more information, contact the MotherToBaby Pregnancy Studies conducted by the Organization of Teratology Information Specialists at 1-877-311-8972 or visit http://mothertobaby.org/pregnancy-studies/ . Risk Summary Available data from published case series, epidemiological studies and reviews with budesonide use in pregnant women have not identified a drug-related risk of major birth defects, miscarriage or other adverse maternal or fetal outcomes. Available data from epidemiological studies and postmarketing case reports of pregnancy outcomes following inhaled albuterol use do not consistently demonstrate a risk of major birth defects or miscarriage. The available epidemiological studies have methodologic limitations, including inconsistent comparator groups, definitions of outcomes, and assessment of disease impact. There are risks to the mother and fetus associated with asthma in pregnancy (see Clinical Considerations) . Animal reproduction studies have not been conducted with AIRSUPRA, however, animal studies are available with its individual components, albuterol and budesonide. Administration of albuterol to mice and rabbits during the period of organogenesis revealed evidence of adverse developmental outcomes (cleft palate in mice, delayed ossification in rabbits) at less than maximum recommended human daily inhalation dose (MRHDID) (see Data) . In animal reproduction studies, budesonide, administered by the subcutaneous route, caused structural abnormalities, was embryocidal, and reduced fetal weights in rats and rabbits at less than the MRHDID in adults, but these effects were not seen in rats that received inhaled doses approximately 2.5 times the MRHDID in adults (see Data) . Experience with oral corticosteroids suggests that rodents are more prone to structural abnormalities from corticosteroid exposure than humans. The background risk of major birth defects and miscarriage of 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% to 4% and 15% to 20%, respectively. Clinical Considerations Disease-Associated Maternal and/or Embryo/Fetal risk In women with poorly or moderately controlled asthma, there is an increased risk of several perinatal adverse outcomes such as preeclampsia in the mother and prematurity, low birth weight, and small for gestational age in the neonate. Pregnant women with asthma should be closely monitored and medication adjusted as necessary to maintain optimal asthma control. Labor or Delivery Because of the potential for beta-agonist interference with uterine contractility, use of AIRSUPRA during labor should be restricted to those patients in whom the benefits clearly outweigh the risk. AIRSUPRA has not been approved for the management of pre-term labor. Serious adverse reactions, including pulmonary edema, have been reported during or following treatment of premature labor with beta 2 -agonists, including albuterol. Data Animal Data Albuterol In a study in pregnant mice, subcutaneously administered albuterol sulfate produced cleft palate formation in 5 of 111 (4.5%) fetuses at an exposure less than the MRHDID in adults (on a mg/m 2 basis at a maternal dose of 0.25 mg/kg) and in 10 of 108 (9.3%) fetuses at approximately 9 times the MRHDID in adults (on a mg/m 2 basis at a maternal dose of 2.5 mg/kg). Cleft palate also occurred in 22 of 72 (30.5%) fetuses from females treated subcutaneously with isoproterenol, another beta 2 -agonist. In a study in pregnant rabbits, orally administered albuterol sulfate produced cranioschisis in 7 of 19 fetuses (37%) at approximately 750 times the MRHDID in adults (on a mg/m 2…

The safety of AIRSUPRA is based on data from 3 trials: MANDALA, DENALI and BATURA [see Clinical Studies (14) ] . All reported safety data is based on patients who received AIRSUPRA 180 mcg/160 mcg. While patients 12 to 17 years of age were included in these trials, AIRSUPRA is not approved in this age group [see Use in Specific Populations (8.4) ] . In MANDALA, AIRSUPRA 180 mcg/160 mcg was administered as needed in patients with asthma who were receiving medium to high dose ICS or low to high dose ICS/LABA, with or without another controller medicine as maintenance therapy. A total of 1015 patients 12 to 84 years of age (mean age: 51 years) received at least one dose of AIRSUPRA and participated in the study for a mean duration of 310 days. Of these, 905 patients were exposed for at least 24 weeks and 323 patients had exposure for at least 1 year. The mean daily use was 2.6 actuations. On the majority of study days, patients used 2 or less actuations; more than 8 actuations were used on less than 2% of study days. The incidence of common adverse reactions in MANDALA is described in Table 1. Table 1 Summary of Adverse Reactions with AIRSUPRA Reported in ≥ 1% of Patients (MANDALA) Adverse Reaction AIRSUPRA 180 mcg/160 mcg N = 1015 (%) AS MDI 1 180 mcg N = 1015 (%) Headache 44 (4.3) 50 (4.9) Oral candidiasis 2 13 (1.3) 5 (0.5) Cough 10 (1.0) 11 (1.1) 1 Albuterol Metered Dose Inhaler = AS MDI 2 Oral candidiasis also includes those reactions reported under the preferred term oropharyngeal candidiasis. The safety profile of AIRSUPRA in MANDALA was similar to that observed with AS MDI, irrespective of background ICS dose. In DENALI, AIRSUPRA 180 mcg/160 mcg was administered 4 times a day for 12 weeks in patients with asthma who were previously treated with as-needed short-acting beta 2 -agonists (SABA) alone or with low-dose ICS maintenance therapy plus as-needed SABA. A total of 197 patients 13 to 81 years of age (mean age: 50 years) received at least one dose of AIRSUPRA. The adverse reactions profile was similar to MANDALA except for the following adverse reactions for AIRSUPRA with an incidence ≥ 1.0% that exceeded the incidence in MANDALA: headache (5.1%), dysphonia (2.0%), and oral/oropharyngeal candidiasis (1.5%), compared to headache (7.1%), dysphonia (0%), and oral/oropharyngeal candidiasis (0%) in the placebo arm. In BATURA, AIRSUPRA 180 mcg/160 mcg was administered as needed for 12 to 52 weeks in patients with asthma who were previously treated with as-needed SABA alone, or as-needed SABA plus background maintenance of either low-…
