Umeclidinium

1 INDICATIONS AND USAGE ANORO ELLIPTA is indicated for the maintenance treatment of patients with chronic obstructive pulmonary disease (COPD). Limitations of Use ANORO ELLIPTA is NOT indicated for the relief of acute bronchospasm or for the treatment of asthma. The safety and effectiveness of ANORO ELLIPTA in asthma have not been established. ANORO ELLIPTA is a combination of umeclidinium, an anticholinergic, and vilanterol, a long-acting beta 2 -adrenergic agonist (LABA), indicated for the maintenance treatment of patients with chronic obstructive pulmonary disease (COPD). ( 1 ) Limitations of Use: Not indicated for relief of acute bronchospasm or for the treatment of asthma. ( 1 , 5.2 )

12.1 Mechanism of Action ANORO ELLIPTA ANORO ELLIPTA contains both umeclidinium and vilanterol. The mechanisms of action described below for the individual components apply to ANORO ELLIPTA. These drugs represent 2 different classes of medications (an anticholinergic and a LABA) each having different effects on clinical and physiological indices. Umeclidinium Umeclidinium is a long-acting muscarinic antagonist, 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 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 methacholine- and acetylcholine-induced bronchoconstrictive effects was dose-dependent and lasted longer than 24 hours. The clinical relevance of these findings is unknown. The bronchodilation following inhalation of umeclidinium is predominantly a site-specific effect. Vilanterol Vilanterol is a LABA. In vitro tests have shown the functional selectivity of vilanterol was similar to salmeterol. The clinical relevance of this in vitro finding is unknown. 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 -adrenergic agonist drugs, including vilanterol, 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, especially from mast cells.

2 DOSAGE AND ADMINISTRATION The recommended dosage of ANORO ELLIPTA for maintenance treatment of COPD is 62.5 mcg umeclidinium and 25 mcg vilanterol (1 actuation of ANORO ELLIPTA 62.5/25 mcg) once daily by oral inhalation. • ANORO ELLIPTA should be used at the same time every day. Do not use ANORO ELLIPTA more than 1 time every 24 hours. • No dosage adjustment is required for geriatric patients, patients with renal impairment, or patients with moderate hepatic impairment [see Clinical Pharmacology ( 12.3 )] . • For oral inhalation only. ( 2 ) • Maintenance treatment of COPD: 1 actuation of ANORO ELLIPTA once daily administered by oral inhalation. ( 2 )

6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in labeling: • Serious asthma-related events–hospitalizations, intubations, death [see Warnings and Precautions ( 5.1 )] • Paradoxical bronchospasm [see Warnings and Precautions ( 5.5 )] • Cardiovascular effects [see Warnings and Precautions ( 5.7 )] • Worsening of narrow-angle glaucoma [see Warnings and Precautions ( 5.9 )] • Worsening of urinary retention [see Warnings and Precautions ( 5.10 )] Most common adverse reactions (incidence ≥1% and more common than placebo) are pharyngitis, sinusitis, lower respiratory tract infection, constipation, diarrhea, pain in extremity, muscle spasms, neck pain, and chest pain.

The clinical program for ANORO ELLIPTA included 8,138 subjects with COPD in four 6‑month lung function trials, one 12-month long-term safety study, and 9 other trials of shorter duration. A total of 1,124 subjects have received at least 1 dose of ANORO ELLIPTA (umeclidinium/vilanterol 62.5/25 mcg), and 1,330 subjects have received a higher dose of umeclidinium/vilanterol (125/25 mcg). The safety data described below are based on the four 6-month and one 12-month trials. Adverse reactions observed in the other trials were similar to those observed in the confirmatory trials. 6-Month Trials The incidence of adverse reactions associated with ANORO ELLIPTA in Table 1 is based on four 6-month trials: 2 placebo-controlled trials (Trial 1 and Trial 2); N = 1,532 and N = 1,489, respectively) and 2 active-controlled trials (Trial 3 and Trial 4); N = 843 and N = 869, respectively). Of the 4,733 subjects, 68% were male and 84% were white. They had a mean age of 63 years and an average smoking history of 45 pack-years, with 50% identified as current smokers. At screening, the mean postbronchodilator percent predicted forced expiratory volume in 1 second (FEV 1 ) was 48% (range: 13% to 76%), the mean postbronchodilator FEV 1 /forced vital capacity (FVC) ratio was 0.47 (range: 0.13 to 0.78), and the mean percent reversibility was 14% (range: -45% to 109%). Subjects received 1 dose once daily of the following: ANORO ELLIPTA, umeclidinium/vilanterol 125/25 mcg, umeclidinium 62.5 mcg, umeclidinium 125 mcg, vilanterol 25 mcg, active control, or placebo.

5 WARNINGS AND PRECAUTIONS • LABA monotherapy (without an inhaled corticosteroid) for asthma increases the risk of serious asthma-related events. ( 5.1 ) • Do not initiate in acutely deteriorating COPD. Do not use to treat acute symptoms. ( 5.2 ) • Do not use in combination with additional therapy containing a LABA because of risk of overdose. ( 5.3 ) • If paradoxical bronchospasm occurs, discontinue ANORO ELLIPTA and institute alternative therapy. ( 5.5 ) • Use with caution in patients with cardiovascular disorders because of beta-adrenergic stimulation. ( 5.7 ) • Use with caution in patients with convulsive disorders, thyrotoxicosis, diabetes mellitus, and ketoacidosis. ( 5.8 ) • 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. ( 5.9 ) • 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. ( 5.10 ) • Be alert to hypokalemia and hyperglycemia. ( 5.11 ) 5.1 Serious Asthma-Related Events – Hospitalizations, Intubations, Death The safety and effectiveness of ANORO ELLIPTA in patients with asthma have not been established. ANORO ELLIPTA is not indicated for the treatment of asthma [see Contraindications ( 4 )] . Use of LABA as monotherapy (without 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 LABA are 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. Salmeterol Multicenter Asthma Research Trial (SMART) A 28-week, placebo-controlled, US trial that compared the safety of another LABA (salmeterol) with placebo, each added to usual asthma therapy, showed an increase in asthma-related deaths in subjects receiving salmeterol (13/13,176 in subjects treated with salmeterol vs. 3/13,179 in subjects treated with placebo; relative risk: 4.37 [95% CI: 1.25, 15.34]). The increased risk of asthma-related death is considered a class effect of LABAs, including vilanterol, one of the active ingredients in ANORO ELLIPTA. No trial adequate to determine whether the rate of asthma-related death is increased in subjects treated with ANORO ELLIPTA has been conducted. Available data do not suggest an increased risk of death with use of LABA in patients with COPD. 5.2 Deterioration of Disease and Acute Episodes ANORO ELLIPTA should not be initiated in patients during rapidly deteriorating or potentially life-threatening episodes of COPD. ANORO ELLIPTA has not been studied in subjects with acutely deteriorating COPD. The initiation of ANORO ELLIPTA in this setting is not appropriate. If ANORO ELLIPTA no longer controls symptoms of bronchoconstriction; the patient’s inhaled, short-acting beta 2 -agonist becomes less effective; or the patient needs more short-acting beta 2 -agonist than usual, these may be markers of deterioration of disease. In this setting, re-evaluate the patient and the COPD treatment regimen at once. The daily dose of ANORO ELLIPTA should not be increased. Increasing use of inhaled, short-acting beta 2 -agonists is a signal of deteriorating disease. In this situation, the patient requires immediate re-evaluation with reassessment of the treatment regimen, giving special consideration to the need for additional therapeutic options. Patients should not use more than 1 inhalation of ANORO ELLIPTA once daily. ANORO ELLIPTA should not be used for the relief of acute symptoms, i.e., as rescue therapy for

4 CONTRAINDICATIONS ANORO ELLIPTA is contraindicated in: • patients with severe hypersensitivity to milk proteins or who have demonstrated hypersensitivity to umeclidinium, vilanterol, or any of the excipients [see Warnings and Precautions (5.6), Description (11)] . • use of a long-acting beta 2 -adrenergic agonist (LABA), including vilanterol, one of the active ingredients in ANORO ELLIPTA, without an inhaled corticosteroid (ICS), in patients with asthma [see Warnings and Precautions (5.1)] . ANORO ELLIPTA is not indicated for the treatment of asthma. • Severe hypersensitivity to milk proteins or any ingredients. ( 4 ) • Use of a LABA, including ANORO ELLIPTA, without an inhaled corticosteroid is contraindicated in patients with asthma. ( 4 )

10 OVERDOSAGE ANORO ELLIPTA contains both umeclidinium and vilanterol; therefore, the risks associated with overdosage for the individual components described below apply to ANORO ELLIPTA. Treatment of overdosage consists of discontinuation of ANORO ELLIPTA 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 medicine can produce bronchospasm. Cardiac monitoring is recommended in cases of overdosage. Umeclidinium High doses of umeclidinium may lead to anticholinergic signs and symptoms. Vilanterol The expected signs and symptoms with overdosage of vilanterol are those of excessive beta-adrenergic stimulation and/or occurrence or exaggeration of any of the signs and symptoms of beta-adrenergic stimulation (e.g., seizures, angina, hypertension or hypotension, tachycardia with rates up to 200 beats/min, arrhythmias, nervousness, headache, tremor, muscle cramps, dry mouth, palpitation, nausea, dizziness, fatigue, malaise, insomnia, hyperglycemia, hypokalemia, metabolic acidosis). As with all inhaled sympathomimetic medicines, cardiac arrest and even death may be associated with an overdose of vilanterol.
