In ETHOS and KRONOS, a total of 2783 subjects have received at least 1 dose of BREZTRI AEROSPHERE 320 mcg/18 mcg/9.6 mcg [see Clinical Studies (14.1) ]. In ETHOS and KRONOS, subjects received one of the following treatments: BREZTRI AEROSPHERE 320 mcg/18 mcg/9.6 mcg, glycopyrrolate and formoterol fumarate (GFF MDI 18 mcg/9.6 mcg), or budesonide and formoterol fumarate (BFF MDI 320 mcg/9.6 mcg). Each treatment was administered twice daily. In ETHOS, a 52-week, randomized, double-blind clinical trial, a total of 2144 subjects with COPD received at least 1 dose of BREZTRI AEROSPHERE 320 mcg/18 mcg/9.6 mcg (mean age: 64.7 years, 84.9% Caucasian, 59.7% male across all treatments) [see Clinical Studies (14.1) ] . In KRONOS, a 24-week, randomized, double-blind clinical trial, with a 28-week long-term safety extension resulting in up to 52 weeks of treatment, a total of 639 subjects received at least 1 dose of BREZTRI AEROSPHERE 320 mcg/18 mcg/9.6 mcg (mean age: 65.2 years, 50.1% Caucasian, 71.2% male across all treatments) [see Clinical Studies (14.1) ] . The incidence of adverse reactions from the 52-week trial (ETHOS) is presented in Table 2 for subjects treated with BREZTRI AEROSPHERE 320 mcg/18 mcg/9.6 mcg, GFF MDI 18 mcg/9.6 mcg, or BFF MDI 320 mcg/9.6 mcg.

7 DRUG INTERACTIONS No formal drug interaction studies have been performed with BREZTRI AEROSPHERE. • Strong cytochrome P450 3A4 inhibitors (e.g. ritonavir): Use with caution. May cause systemic corticosteroid effects. ( 7.1 ) • Other adrenergic drugs may potentiate effect: Use with caution. ( 7.2 ) • Diuretics, xanthine derivatives or steroids may potentiate hypokalemia or ECG changes. Use with caution. ( 7.3 , 7.4 ) • Monoamine oxidase inhibitors and tricyclic antidepressants: Use with extreme caution. May potentiate effect of formoterol fumarate on cardiovascular system. ( 7.5 ) • Beta-blockers: Use with caution. May block bronchodilatory effects of beta-agonists and produce severe bronchospasm. ( 7.6 ) • Anticholinergics: May interact additively with concomitantly used anticholinergic medications. Avoid administration of BREZTRI AEROSPHERE with other anticholinergic-containing drugs. ( 7.7 ) 7.1 Inhibitors of Cytochrome P450 3A4 The main route of metabolism of corticosteroids, including budesonide, a component of BREZTRI AEROSPHERE, is via cytochrome P450 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 coadministration of BREZTRI AEROSPHERE 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 (5.9) ] . 7.2 Adrenergic Drugs If additional adrenergic drugs are to be administered by any route, they should be used with caution because the sympathetic effects of formoterol, a component of BREZTRI AEROSPHERE, may be potentiated [see Warnings and Precautions (5.3) ] . 7.3 Xanthine Derivatives, Steroids, or Diuretics Concomitant treatment with xanthine derivatives, steroids, or diuretics may potentiate the hypokalemic effect of beta 2 -adrenergic agonists such as formoterol, a component of BREZTRI AEROSPHERE. 7.4 Non-Potassium Sparing Diuretics The hypokalemia and/or ECG changes that may result from the administration of non-potassium sparing diuretics (such as loop or thiazide diuretics) can be acutely worsened by beta 2 -agonists, especially when the recommended dose of the beta 2 -agonist is exceeded. 7.5 Monoamine Oxidase Inhibitors, Tricyclic Antidepressants, QTc Prolonging Drugs BREZTRI AEROSPHERE, as with other beta 2 -agonists, should be administered with extreme caution to patients being treated with monoamine oxidase inhibitors or tricyclic antidepressants or other drugs known to prolong the QTc interval because the action of adrenergic agonists on the cardiovascular system may be potentiated by these agents. Drugs that are known to prolong the QTc interval may be associated with an increased risk of ventricular arrhythmias. 7.6 Beta-adrenergic Receptor Blocking Agents Beta-adrenergic receptor antagonists (beta-blockers) and BREZTRI AEROSPHERE may interfere with the effect of each other when administered concurrently. Beta-blockers not only block the therapeutic effects of beta 2 -agonists, but may produce severe bronchospasm in COPD and asthma patients. Therefore, patients with COPD or 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-blockers in patients with COPD or asthma. In this setting, cardioselective beta-blockers could be considered, although they should be administered with caution. 7.7 Anticholinergics There is a potential for an additive interaction with concomitantly used anticholinergic medications. Therefore, avoid coadministration of BREZTRI AEROSPHERE with other anticholinergic-containing …

8 USE IN SPECIFIC POPULATIONS Hepatic impairment: Budesonide and formoterol fumarate systemic exposure may increase in patients with severe hepatic impairment. Monitor patients for signs of increased drug exposure. ( 8.6 , 12.3 ) Renal impairment: In patients with severe renal impairment, use should be considered only if the potential benefit of the treatment outweighs the risk ( 8.7 ). 8.1 Pregnancy Risk Summary There are no adequate and well-controlled studies with BREZTRI AEROSPHERE or with two of its individual components, glycopyrrolate or formoterol fumarate, in pregnant women to inform a drug-associated risk; however, studies are available for the other component, budesonide. In animal reproduction studies, budesonide alone, administered by the subcutaneous route, caused structural abnormalities, was embryocidal, and reduced fetal weights in rats and rabbits at 0.3 and 0.75 times maximum recommended human daily inhaled dose (MRHDID), respectively, but these effects were not seen in rats that received inhaled doses up to 4 times the MRHDID. Studies of pregnant women who received inhaled budesonide alone during pregnancy have not shown increased risk of abnormalities. Experience with oral corticosteroids suggests that rodents are more prone to teratogenic effects from corticosteroid exposure than humans. Formoterol fumarate alone, administered by the oral route in rats and rabbits, caused structural abnormalities at 1500 and 61,000 times the MRHDID, respectively. Formoterol fumarate was also embryocidal, increased pup loss at birth and during lactation, and decreased pup weight in rats at 110 times the MRHDID. These adverse effects generally occurred at large multiples of the MRHDID when formoterol fumarate was administered by the oral route to achieve high systemic exposures. No structural abnormalities, embryocidal, or developmental effects were seen in rats that received inhalation doses up to 350 times the MRHDID. Glycopyrrolate alone, administered by the subcutaneous route in rats and rabbits, did not cause structural abnormalities or affect fetal survival at exposures approximately 1350 and 2700 times from MRHDID, respectively. Glycopyrrolate had no effects on the physical, functional, and behavioral development of rat pups with exposures up to 1350 times the MRHDID. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. 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. 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: There are no well-controlled human trials that have investigated the effects of BREZTRI AEROSPHERE on preterm labor or labor at term. Because of the potential for beta-agonist interference with uterine contractility, use of BREZTRI AEROSPHERE during labor should be restricted to those patients in whom the benefits clearly outweigh the risks. Data Human Data Studies of pregnant women have not shown that inhaled budesonide increases the risk of abnormalities when administered during pregnancy. The results from a large population-based prospective cohort epidemiological study reviewing data from three Swedish registries covering approximately 99% of the pregnancies from 1995-1997 (i.e., Swedish Medical Birth Registry; Registry of Congenital Malformations; Child Cardiology Registry) indicate no increased risk for congenital malformations from the use of inhaled budesonide during early pregnancy. Congenital malformations were stud …

12.1 Mechanism of Action BREZTRI AEROSPHERE BREZTRI AEROSPHERE contains budesonide, glycopyrrolate, and formoterol fumarate. The mechanism of action described below for the individual components applies to BREZTRI AEROSPHERE. These drugs represent three different classes of medications (a synthetic corticosteroid, an anticholinergic, and a long-acting selective beta 2 -adrenoceptor agonist) that have different effects on clinical physiology and inflammatory indices of COPD and asthma. Budesonide Budesonide is an anti-inflammatory corticosteroid that exhibits potent glucocorticoid activity and weak mineralocorticoid activity. In standard in vitro and animal models, budesonide has approximately a 200-fold higher affinity for the glucocorticoid receptor and a 1000-fold higher topical anti-inflammatory potency than cortisol (rat croton oil ear edema assay). As a measure of systemic activity, budesonide is 40 times more potent than cortisol when administered subcutaneously and 25 times more potent when administered orally in the rat thymus involution assay. In glucocorticoid receptor affinity studies, the 22R epimer of budesonide was two times as active as the 22S epimer. In vitro studies indicated that the two forms of budesonide do not interconvert. Inflammation is an important component in the pathogenesis of COPD and asthma. Corticosteroids have a wide range of inhibitory activities against multiple cell types (e.g., mast cells, eosinophils, neutrophils, macrophages, and lymphocytes) and mediators (e.g., histamine, eicosanoids, leukotrienes, and cytokines) involved in allergic and non-allergic-mediated inflammation. These anti-inflammatory actions of corticosteroids may contribute to their efficacy. Glycopyrrolate Glycopyrrolate is a long-acting antimuscarinic agent which is often referred to as an anticholinergic. It has similar affinity to the subtypes of muscarinic receptors M1 to M5. In the airways, it exhibits pharmacological effects through inhibition of the M3 receptor at the smooth muscle leading to bronchodilation. The competitive and reversible nature of antagonism was shown with human and animal origin receptors and isolated organ preparations. In preclinical in vitro as well as in vivo studies, prevention of methylcholine and acetylcholine-induced bronchoconstrictive effects was dose-dependent and lasted more than 12 hours. The clinical relevance of these findings is unknown. The bronchodilation following inhalation of glycopyrrolate is predominantly a site-specific effect. Formoterol Fumarate Formoterol fumarate is a long-acting selective beta 2 -adrenergic agonist (beta 2 -agonist) with a rapid onset of action. Inhaled formoterol fumarate acts locally in the lung as a bronchodilator. In vitro studies have shown that formoterol has more than 200-fold greater agonist activity at beta 2 -receptors than at beta 1 -receptors. The in vitro binding selectivity to beta 2 - over beta 1 -adrenoceptors is higher for formoterol than for albuterol (5 times), whereas salmeterol has a higher (3 times) beta 2 -selectivity ratio than formoterol. Although beta 2 -receptors are the predominant adrenergic receptors in bronchial smooth muscle and beta 1 -receptors are the predominant receptors in the heart, there are also beta 2 -receptors in the human heart comprising 10% to 50% of the total beta-adrenergic receptors. The precise function of these receptors has not been established, but they raise the possibility that even highly selective beta 2 -agonists may have cardiac effects. The pharmacologic effects of beta 2 -adrenoceptor agonist drugs, including formoterol fumarate, are at least in part attributable to stimulation of intracellular adenyl cyclase, the enzyme that catalyzes the conversion of adenosine triphosphate (ATP) to cyclic-3',5'-adenosine monophosphate (cyclic AMP). Increased cyclic AMP levels cause relaxation of bronchial smooth muscle and inhibition of release of mediators of immediate hypersensitivity from cells, es …

Budesonide is a corticosteroid with the following chemical name: (RS)-11β, 16α, 17,21-Tetrahydroxypregna-1,4-diene-3,20-dione cyclic 16,17-acetal with butyraldehyde. Budesonide is a white to off-white, powder which is practically insoluble in water. The molecular formula is C 25 H 34 O 6 and the molecular weight is 430.54. The structural formula is as follows: Budesonide contains nine chiral centers and is a mixture of the two epimers (22R and 22S). Glycopyrrolate is a quaternary ammonium salt with the following chemical name: (RS)-[3-(SR)-Hydroxy-1,1-dimethylpyrrolidinium bromide] α-cyclopentylmandelate. Glycopyrrolate is a powder that is freely soluble in water. The molecular formula is C 19 H 28 BrNO 3 , and the molecular weight is 398.33 g/mol. The structural formula is as follows: Glycopyrrolate contains two chiral centers and is a racemate of a 1:1 mixture of the R,S and S,R diastereomers. The active moiety, glycopyrronium, is the positively charged ion of glycopyrrolate. Formoterol fumarate has the chemical name N-[2-Hydroxy-5-[(1RS)-1-hydroxy-2-[[(1RS)-2-(4-methoxyphenyl)-1-methylethyl]-amino] ethyl]phenyl] formamide, (E)-2-butenedioate dihydrate. Formoterol fumarate is a powder that is slightly soluble in water. The molecular formula is (C 19 H 24 N 2 O 4 ) 2 ·C 4 H 4 O 4 ·2H 2 O and the molecular weight is 840.91 g/mol. The structural formula is as follows: Formoterol fumarate contains two chiral centers and consists of a single enantiomeric pair (a racemate of R,R and S,S). BREZTRI AEROSPHERE is formulated as a hydrofluoroalkane (HFA 134a) propelled pressurized metered dose inhaler containing 28 or 120 inhalations. The canister has an attached dose indicator and is supplied with a yellow plastic actuator and white mouthpiece with a grey dust cap. After priming, each actuation of the inhaler meters 170 mcg of budesonide, 9.6 or 19.1 mcg of glycopyrrolate (equivalent to 7.7 or 15.3 mcg of glycopyrronium), and 5.1 mcg of formoterol fumarate (equivalent to 4.4 mcg of formoterol) from the valve which delivers 160 mcg of budesonide, 9.0 or 18 mcg of glycopyrrolate (equivalent to 7.2 or 14.4 mcg of glycopyrronium), and 4.8 mcg of formoterol fumarate (equivalent to 4.1 mcg of formoterol) from the actuator. The actual amount of drug delivered to the lung may depend on patient factors, such as the coordination between actuation of the device and inspiration through the delivery system. BREZTRI AEROSPHERE also contains porous particles that form a co-suspension with the drug crystals. The porous particles are comprised of the phospholipid, 1,2-distearoyl- sn -glycero-3-phosphocholine (DSPC), and calcium chloride. Porous particles and HFA 134a are excipients in the formulation.

10 OVERDOSAGE BREZTRI AEROSPHERE contains budesonide, glycopyrrolate, and formoterol fumarate; therefore, the risks associated with overdosage for the individual components described below apply to BREZTRI AEROSPHERE. Treatment of overdosage consists of discontinuation of BREZTRI AEROSPHERE together with institution of appropriate symptomatic and/or supportive therapy. The judicious use of a cardioselective beta-receptor blocker may be considered, bearing in mind that such medication can produce bronchospasm. Cardiac monitoring is recommended in case of overdosage. Budesonide If used at excessive doses for prolonged periods, systemic corticosteroid effects, such as hypercorticism may occur [see Warnings and Precautions (5.8) ] . Glycopyrrolate High doses of glycopyrrolate, a component of BREZTRI AEROSPHERE, may lead to anticholinergic signs and symptoms such as nausea, vomiting, dizziness, lightheadedness, blurred vision, increased intraocular pressure (causing pain, vision disturbances or reddening of the eye), obstipation, or difficulties in voiding. Formoterol Fumarate An overdose of formoterol fumarate would likely lead to an exaggeration of effects that are typical for beta 2 -agonists: seizures, angina, hypertension, hypotension, tachycardia, atrial and ventricular tachyarrhythmias, nervousness, headache, tremor, palpitations, muscle cramps, nausea, dizziness, sleep disturbances, metabolic acidosis, hyperglycemia, hypokalemia. As with all sympathomimetic medications, cardiac arrest, and even death may be associated with overdosage of formoterol fumarate.
