2 DOSAGE AND ADMINISTRATION • For oral inhalation only. ( 2 ) • Prime BREZTRI AEROSPHERE before first time use and re-prime if not used for more than 7 days. ( 2.1 ) • Maintenance treatment of COPD: 2 inhalations of BREZTRI AEROSPHERE 160 mcg/9 mcg/4.8 mcg twice daily administered by oral inhalation. ( 2.2 ) • Maintenance treatment of asthma: 2 inhalations of BREZTRI AEROSPHERE 160 mcg/18 mcg/4.8 mcg twice daily administered by oral inhalation. ( 2.3 ) 2.1 Preparation and Administration Information BREZTRI AEROSPHERE should be administered as 2 inhalations twice daily, in the morning and in the evening, by oral inhalation. Do not take more than two inhalations twice daily. After inhalation, rinse mouth with water without swallowing [see Warnings and Precautions (5.4) ] . Priming Before Use Priming BREZTRI AEROSPHERE is essential to ensure appropriate drug content in each actuation. Prime BREZTRI AEROSPHERE before using for the first time. Prime BREZTRI AEROSPHERE by releasing 4 sprays into the air away from the face, shaking well before each spray. Re-prime BREZTRI AEROSPHERE if the inhaler has not been used for more than 7 days, is dropped, or after weekly rinsing. Prime BREZTRI AEROSPHERE by releasing 2 sprays into the air away from the face, shaking well before each spray. Dose counter BREZTRI AEROSPHERE canister has an attached dose indicator (also known as puff indicator), which indicates how many inhalations (puffs) remain. The dose indicator display has a pointer which will move after every actuation. When nearing the end of the usable inhalations, the pointer is in the yellow zone. BREZTRI AEROSPHERE should be discarded when the pointer is at zero in the red zone of the dose indicator. 2.2 Recommended Dosage for Maintenance Treatment of Chronic Obstructive Pulmonary Disease The recommended dosage of BREZTRI AEROSPHERE for treatment of COPD is budesonide 320 mcg, glycopyrrolate 18 mcg, and formoterol fumarate 9.6 mcg (administered as 2 inhalations of BREZTRI AEROSPHERE 160 mcg/9 mcg/4.8 mcg [budesonide 160 mcg, glycopyrrolate 9 mcg, and formoterol fumarate 4.8 mcg]) twice daily, in the morning and in the evening, by oral inhalation. 2.3 Recommended Dosage for Maintenance Treatment of Asthma The recommended dosage of BREZTRI AEROSPHERE for maintenance treatment of asthma is budesonide 320 mcg, glycopyrrolate 36 mcg, and formoterol fumarate 9.6 mcg (administered as 2 inhalations of BREZTRI AEROSPHERE 160 mcg/18 mcg/4.8 mcg [budesonide 160 mcg, glycopyrrolate 18 mcg, and formoterol fumarate 4.8 mcg]) twice daily, in the morning and in the evening, by oral inhalation. 2.1 Preparation and Administration Information BREZTRI AEROSPHERE should be administered as 2 inhalations twice daily, in the morning and in the evening, by oral inhalation.

5 WARNINGS AND PRECAUTIONS • LABA as monotherapy (without an inhaled-corticosteroid) is associated with an increased risk of serious asthma-related events. ( 5.1 ) • Do not initiate in acutely deteriorating COPD or asthma. Do not use to relieve acute symptoms. ( 5.2 ) • Do not use in combination with an additional therapy containing a LABA because of the risk of overdose. ( 5.3 ) • Candida albicans infection of the mouth and pharynx may occur. Monitor patients periodically. Advise the patient to rinse his/her mouth with water without swallowing after inhalation to help reduce the risk. ( 5.4 ) • Increased risk of pneumonia in patients with COPD. Monitor patients for signs and symptoms of pneumonia. ( 5.5 ) • Potential worsening of infections (e.g., existing tuberculosis; fungal, bacterial, viral, or parasitic infections; 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. ( 5.6 ) • Risk of impaired adrenal function when transferring from systemic corticosteroids. Taper patients slowly from systemic corticosteroids if transferring to BREZTRI AEROSPHERE. ( 5.7 ) • Hypercorticism and adrenal suppression may occur with very high dosages or at the regular dosage in susceptible individuals. If such changes occur, consider appropriate therapy. ( 5.8 ) • If paradoxical bronchospasm occurs, discontinue BREZTRI AEROSPHERE and institute alternative therapy. ( 5.10 ) • Use with caution in patients with cardiovascular disorders because of beta-adrenergic stimulation. ( 5.12 ) • Assess for decrease in bone mineral density initially and periodically thereafter. ( 5.13 ) • Monitor growth in pediatric patients. ( 5.14 ) • Glaucoma and cataracts may occur with long-term use of ICS. Worsening of narrow-angle glaucoma may occur. Use with caution in patients with narrow-angle glaucoma and instruct patients to contact a healthcare provider immediately if symptoms occur. Consider referral to an ophthalmologist in patients who develop ocular symptoms or use BREZTRI AEROSPHERE long term. ( 5.15 ) • Worsening of urinary retention may occur. Use with caution in patients with prostatic hyperplasia or bladder-neck obstruction and instruct patients to contact a healthcare provider immediately if symptoms occur. ( 5.16 ) • Use with caution in patients with convulsive disorders, thyrotoxicosis, diabetes mellitus, and ketoacidosis. ( 5.17 ) • Be alert to hypokalemia and hyperglycemia. ( 5.18 ) 5.1 Serious Asthma-Related Events – Hospitalizations, Intubations, Death Use of long-acting beta 2 -adrenergic agonists (LABA) as monotherapy [without inhaled corticosteroid (ICS)] for asthma is associated with an increased risk of asthma-related death. Available data from controlled clinical trials also suggest that use of LABA as monotherapy increases the risk of asthma-related hospitalization in pediatric and adolescent patients. These findings are considered a class effect of LABA monotherapy. When a LABA is used in fixed‑dose combination with ICS, data from large clinical trials do not show a significant increase in the risk of serious asthma-related events (hospitalizations, intubations, death) compared with ICS alone (see Serious Asthma-Related Events with ICS/LABA) . Available data do not suggest an increased risk of death with use of LABA in patients with COPD. Serious Asthma-Related Events with ICS/LABA Four large, 26-week, randomized, blinded, active-controlled clinical safety trials were conducted to evaluate the risk of serious asthma-related events when LABA were used in fixed-dose combination with ICS compared to ICS alone in patients with asthma. Three trials included adult and adolescent patients aged ≥12 years: one trial compared budesonide/formoterol to budesonide; one trial compared fluticasone propionate/salmeterol inhalation powder to fluticasone propionate inhalation powder; and one trial compared mometasone furoate/formoterol to m…

4 CONTRAINDICATIONS BREZTRI AEROSPHERE is contraindicated in the following conditions: • Primary treatment of status asthmaticus or other acute episodes of COPD or asthma where intensive measures are required [see Warnings and Precautions (5.2) ] . • Hypersensitivity to budesonide, glycopyrrolate, formoterol, or any of the excipients [see Warnings and Precautions (5.11) and Description (11) ] . • Primary treatment of status asthmaticus or other acute episodes of asthma or COPD requiring intensive measures. ( 4 ) • Hypersensitivity to budesonide, glycopyrrolate, formoterol fumarate, or to any of the excipients. ( 4 )

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 …

8.1 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 studied in 2014 infants born to mothers reporting the use of inhaled budesonide for asthma in early pregnancy (usually 10-12 weeks after the last menstrual period), the period when most major organ malformations occur. The rate of recorded congenital malformations was similar compared to the general population rate (3.8% vs. 3.5%, respectively). In addition, after exposure to inhaled budeson…
