Olodaterol Respimat Inhalation Spray

11 DESCRIPTION The active moiety olodaterol is a selective beta 2 -adrenergic bronchodilator. The drug substance, olodaterol hydrochloride, is chemically described as 2H-1,4-Benzoxazin-3H(4H)-one, 6-hydroxy-8-[(1R)-1-hydroxy-2-[[2-(4-methoxyphenyl)-1,1-dimethylethyl]-amino]ethyl]-, monohydrochloride. Olodaterol hydrochloride is a white to off-white powder that is sparingly-slightly soluble in water and slightly soluble in ethanol. The molecular weight is 422.9 g/mole (salt): 386.5 g/mole (base), and the molecular formula is C 21 H 26 N 2 O 5 × HCl as a hydrochloride. The conversion factor from salt to free base is 1.094. The structural formula is: The drug product, STRIVERDI RESPIMAT, is composed of a sterile, aqueous solution of olodaterol hydrochloride filled into a 4.5 mL plastic container crimped into an aluminum cylinder (STRIVERDI RESPIMAT cartridge) for use with the STRIVERDI RESPIMAT inhaler. Excipients include anhydrous citric acid, benzalkonium chloride, edetate disodium, and water for injection. The STRIVERDI RESPIMAT cartridge is only intended for use with the STRIVERDI RESPIMAT inhaler. The STRIVERDI RESPIMAT inhaler is a hand held, pocket sized oral inhalation device that uses mechanical energy to generate a slow-moving aerosol cloud of medication from a metered volume of the drug solution. The STRIVERDI RESPIMAT inhaler has a yellow-colored cap. When used with the STRIVERDI RESPIMAT inhaler, each cartridge containing a minimum of 4 grams of a sterile aqueous solution delivers the labeled number of metered actuations after preparation for use. Each dose (one dose equals two actuations) from the STRIVERDI RESPIMAT inhaler delivers 5 mcg olodaterol (equivalent to 5.473 mcg olodaterol hydrochloride) in 22.1 mcL of solution from the mouthpiece. As with all inhaled drugs, the actual amount of drug delivered to the lung may depend on patient factors, such as the coordination between the actuation of the inhaler and inspiration through the delivery system. The duration of inspiration should be at least as long as the spray duration (1.5 seconds). Prior to first use, the STRIVERDI RESPIMAT cartridge is inserted into the STRIVERDI RESPIMAT inhaler and the unit is primed. When using for the first time, patients are to actuate the inhaler toward the ground until an aerosol cloud is visible and then repeat the process three more times. The unit is then considered primed and ready for use. If not used for more than 3 days, patients are to actuate the inhaler once to prepare the inhaler for use. If not used for more than 21 days, patients are to actuate the inhaler until an aerosol cloud is visible and then repeat the process three more times to prepare the inhaler for use [see Patient Counseling Information (17) ] . Chemical Structure

5 WARNINGS AND PRECAUTIONS LABA as monotherapy (without an inhaled corticosteroid) for asthma increases the risk of serious asthma-related events. ( 5.1 ) Do not initiate STRIVERDI RESPIMAT in acutely deteriorating COPD patients. ( 5.2 ) Do not use for relief of acute symptoms. Concomitant short-acting beta 2 -agonists can be used as needed for acute relief. ( 5.2 ) Do not exceed the recommended dosage. Excessive use of STRIVERDI RESPIMAT, or use in conjunction with other medications containing LABA can result in clinically significant cardiovascular effects and may be fatal. ( 5.3 ) Life-threatening paradoxical bronchospasm can occur. Discontinue STRIVERDI RESPIMAT immediately. ( 5.4 ) Use with caution in patients with cardiovascular or convulsive disorders, thyrotoxicosis or sensitivity to sympathomimetic drugs. ( 5.5 , 5.6 ) 5.1 Serious Asthma-Related Events – Hospitalizations, Intubations, Death The safety and efficacy of STRIVERDI RESPIMAT in patients with asthma have not been established. STRIVERDI RESPIMAT is not indicated for the treatment of asthma [see Contraindications (4) ] . Use of long-acting beta 2 -adrenergic agonists (LABA) as monotherapy [without inhaled corticosteroids (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. A 28-week, placebo-controlled US study comparing the safety of another LABA (salmeterol) with placebo, each added to usual asthma therapy, showed an increase in asthma-related deaths in patients receiving salmeterol (13/13,176 in patients treated with salmeterol vs. 3/13,179 in patients treated with placebo; RR 4.37, 95% CI 1.25, 15.34). The increased risk of asthma-related death is considered a class effect of LABA, including STRIVERDI RESPIMAT. No study adequate to determine whether the rate of asthma-related death is increased in patients treated with STRIVERDI RESPIMAT 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 STRIVERDI RESPIMAT should not be initiated in patients with acutely deteriorating COPD, which may be a life-threatening condition. STRIVERDI RESPIMAT has not been studied in patients with acutely deteriorating COPD. The use of STRIVERDI RESPIMAT in this setting is inappropriate. STRIVERDI RESPIMAT should not be used for the relief of acute symptoms, i.e., as rescue therapy for the treatment of acute episodes of bronchospasm. STRIVERDI RESPIMAT has not been studied in the relief of acute symptoms and extra doses should not be used for that purpose. Acute symptoms should be treated with an inhaled short-acting beta 2 -agonist. When beginning STRIVERDI RESPIMAT, patients who have been taking inhaled, short-acting beta 2 -agonists on a regular basis (e.g., four times a day) should be instructed to discontinue the regular use of these drugs and use them only for symptomatic relief of acute respiratory symptoms. When prescribing STRIVERDI RESPIMAT, the healthcare provider should also prescribe an inhaled, short-acting beta 2 -agonist and instruct the patient on how it should be used. Increasing inhaled beta 2 -agonist use is a signal of deteriorating disease for which prompt medical attention is indicated. COPD may deteriorate acutely over a period of hours or chronically over several days or longer. If STRIVERDI RESPIMAT no longer controls symptoms of bronchoconstriction, or the patient’s inhaled, short-acting beta 2 -agonist becomes less effective or the patient needs more inhalation of short-acting beta 2 -agonist than usual, these may be markers of deterioration of disease. In this setting, a re-evaluation of the patient and the COPD treatment regimen should be undertaken at once. Increasing the daily dosage of STRIVERDI RESPIMAT beyond the recommended dosage is not appropriate in this situation. 5.3 Excessive Use of STRIVERDI RESPIMAT and Use with Long-Acting Beta 2 -Agonists As with other inhaled drugs containing beta 2 -adrenergic agents, STRIVERDI RESPIMAT should not be used more often than recommended, at higher doses than recommended, or in conjunction with other medications containing long-acting beta 2 -agonists, as an overdose may result. Clinically significant cardiovascular effects and fatalities have been reported in association with excessive use of inhaled sympathomimetic drugs. 5.4 Paradoxical Bronchospasm As with other inhaled beta 2 -agonists, STRIVERDI RESPIMAT may produce paradoxical bronchospasm that may be life-threatening. If paradoxical bronchospasm occurs, STRIVERDI RESPIMAT should be discontinued immediately and alternative therapy instituted. 5.5 Cardiovascular Effects STRIVERDI RESPIMAT, like other beta 2 -agonists, can produce a clinically significant cardiovascular effect in some patients as measured by increases in pulse rate, systolic or diastolic blood pressure, and/or symptoms. If such effects occur, STRIVERDI RESPIMAT may need to be discontinued. In addition, beta-agonists have been reported to produce 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. Long acting beta 2 -adrenergic agonists should be administered with caution in patients with cardiovascular disorders, especially coronary insufficiency, cardiac arrhythmias, hypertrophic obstructive cardiomyopathy, and hypertension. 5.6 Co-existing Conditions STRIVERDI RESPIMAT, like other sympathomimetic amines, should be used with caution in patients with convulsive disorders or thyrotoxicosis, in patients with known or suspected prolongation of the QT interval, and in patients who are unusually responsive to sympathomimetic amines. Doses of the related beta 2 -agonist albuterol, when administered intravenously, have been reported to aggravate pre-existing diabetes mellitus and ketoacidosis. 5.7 Hypokalemia and Hyperglycemia Beta-adrenergic agonists may produce significant hypokalemia in some patients, which has the potential to produce adverse cardiovascular effects [see Clinical Pharmacology (12.2) ] . The decrease in serum potassium is usually transient, not requiring supplementation. Inhalation of high doses of beta 2 -adrenergic agonists may produce increases in plasma glucose. In patients with severe COPD, hypokalemia may be potentiated by hypoxia and concomitant treatment [see Drug Interactions (7.2) ] , which may increase the susceptibility for cardiac arrhythmias. Clinically notable decreases in serum potassium or changes in blood glucose were infrequent during clinical studies with long-term administration of STRIVERDI RESPIMAT with the rates similar to those for placebo controls. STRIVERDI RESPIMAT has not been investigated in patients whose diabetes mellitus is not well controlled. 5.8 Hypersensitivity Reactions Immediate hypersensitivity reactions, including angioedema, may occur after administration of STRIVERDI RESPIMAT. If such a reaction occurs, therapy with STRIVERDI RESPIMAT should be stopped at once and alternative treatment should be considered.

6 ADVERSE REACTIONS Long-acting beta 2 -adrenergic agonists, such as STRIVERDI RESPIMAT, as monotherapy (without an inhaled corticosteroid) for asthma, increase the risk of asthma-related events. STRIVERDI RESPIMAT is not indicated for the treatment of asthma [see Warnings and Precautions (5.1) ] . Most common adverse reactions (incidence ≥2% and more than placebo) are nasopharyngitis, upper respiratory tract infection, bronchitis, urinary tract infection, cough, dizziness, rash, diarrhea, back pain and arthralgia. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Boehringer Ingelheim Pharmaceuticals, Inc. at 1-800-542-6257 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience in Chronic Obstructive Pulmonary Disease Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug and may not reflect the rates observed in practice. The STRIVERDI RESPIMAT clinical development program included seven dose-ranging trials and eight confirmatory trials. Four of the confirmatory trials were 6-week cross-over trials and four were 48-week parallel group trials. Adverse reactions observed in the dose-ranging trials and four 6-week cross-over trials were consistent with those observed in the 48-week parallel group trials, which formed the primary safety database. The primary safety database consisted of pooled data from the four 48-week double-blind, active and placebo-controlled, parallel group confirmatory clinical trials. These trials included 3,104 adult COPD patients (77% males and 23% females) 40 years of age and older. Of these patients, 876 and 883 patients were treated with STRIVERDI RESPIMAT 5 mcg and 10 mcg once-daily, respectively. The STRIVERDI RESPIMAT groups were composed of mostly Caucasians (66%) with a mean age of 64 years and a mean percent predicted FEV 1 at baseline of 44% for both the 5 mcg and 10 mcg treatment groups. Control arms for comparison included placebo in all four trials plus formoterol 12 mcg in two trials. In these four clinical trials, seventy-two percent (72%) of patients exposed to any dose of STRIVERDI RESPIMAT reported an adverse reaction compared to 71% in the placebo group. The proportion of patients who discontinued due to an adverse reaction was 7.2% for STRIVERDI RESPIMAT treated patients compared to 8.8% for placebo treated patients. The adverse reaction most commonly leading to discontinuation was worsening COPD. The most common serious adverse reactions were COPD exacerbation, pneumonia, and atrial fibrillation. Table 1 shows all adverse drug reactions reported by at least 2% of patients (and higher than placebo) who received STRIVERDI RESPIMAT 5 mcg during the 48-week trials. Table 1 Number and frequency of adverse drug reactions greater than 2% (and higher than placebo) in COPD patients exposed to STRIVERDI RESPIMAT 5 mcg: Pooled data from the four 48-week, double-blind, active- and placebo-controlled clinical trials in COPD patients 40 years of age and older Treatment STRIVERDI 5 mcg once-daily Placebo Body system (adverse drug reaction) n=876 n (%) n=885 n (%) *Rash includes a grouping of similar terms Infections and infestations Nasopharyngitis 99 (11.3) 68 (7.7) Upper Respiratory Tract Infection 72 (8.2) 66 (7.5) Bronchitis 41 (4.7) 32 (3.6) Urinary Tract Infection 22 (2.5) 9 (1.0) Respiratory, thoracic, and mediastinal disorders Cough 37 (4.2) 35 (4.0) Nervous system disorders Dizziness 20 (2.3) 19 (2.1) Skin and subcutaneous tissue disorders Rash* 19 (2.2) 10 (1.1) Gastrointestinal disorders Diarrhea 25 (2.9) 22 (2.5) Musculoskeletal and connective tissue disorders Back Pain 31 (3.5) 24 (2.7) Arthralgia 18 (2.1) 7 (0.8) Additional adverse reactions that occurred in greater than 2% (and higher than placebo) of patients exposed to STRIVERDI RESPIMAT 10 mcg were pneumonia, constipation, and pyrexia. Lung cancers were reported in 6 (0.7%), 3 (0.3%), and 2 (0.2%) patients who received STRIVERDI RESPIMAT 10 mcg, 5 mcg, and placebo, respectively.

7 DRUG INTERACTIONS Other adrenergic drugs may potentiate effect. Use with caution. ( 5.3 , 7.1 ) Xanthine derivatives, steroids, diuretics or non-potassium sparing diuretics may potentiate hypokalemia or ECG changes. Use with caution. ( 7.2 , 7.3 ) MAO inhibitors, tricyclic antidepressants, and drugs that prolong QTc interval may potentiate effect on cardiovascular system. Use with extreme caution. ( 7.4 ) Beta-blockers may decrease effectiveness. Use with caution and only when medically necessary. ( 7.5 ) 7.1 Adrenergic Drugs If additional adrenergic drugs are to be administered by any route, they should be used with caution because the sympathetic effects of STRIVERDI RESPIMAT may be potentiated [see Warnings and Precautions (5.3 , 5.5 , 5.6 , 5.7) ] . 7.2 Xanthine Derivatives, Steroids, or Diuretics Concomitant treatment with xanthine derivatives, steroids, or diuretics may potentiate any hypokalemic effect of STRIVERDI RESPIMAT [see Warnings and Precautions (5.7) ] . 7.3 Non-Potassium Sparing Diuretics The ECG changes and/or hypokalemia that 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 dosage of the beta-agonist is exceeded. Although the clinical significance of these effects is not known, caution is advised in the co-administration of beta-agonists with non-potassium-sparing diuretics. 7.4 Monoamine Oxidase Inhibitors, Tricyclic Antidepressants, QTc Prolonging Drugs STRIVERDI RESPIMAT, 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. 7.5 Beta-Blockers Beta-adrenergic receptor antagonists (beta-blockers) and STRIVERDI RESPIMAT may interfere with the effect of each other when administered concurrently. Beta-blockers not only block the therapeutic effects of beta-agonists, but may produce severe bronchospasm in COPD patients. Therefore, patients with COPD 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. In this setting, cardioselective beta-blockers could be considered, although they should be administered with caution. 7.6 Inhibitors of Cytochrome P450 and P-gp Efflux Transporter In a drug interaction study using the strong dual CYP and P-gp inhibitor ketoconazole, a 1.7-fold increase of maximum plasma concentrations and AUC was observed [see Clinical Pharmacology (12.3) ] . STRIVERDI RESPIMAT was evaluated in clinical trials for up to one year at doses up to twice the recommended therapeutic dosage. No dosage adjustment is necessary.

8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Risk Summary There are no adequate and well-controlled clinical studies with STRIVERDI RESPIMAT in pregnant women to inform of drug-associated risk of adverse pregnancy-related outcomes. There are clinical considerations with the use of STRIVERDI RESPIMAT in pregnant women (see Clinical Considerations ) . Based on animal studies, olodaterol was not teratogenic when administered to pregnant rats or rabbits during organogenesis at inhalation doses of approximately 2,731 or 1,353 times the maximum recommended human daily inhalation dose (MRHDID) (on an AUC basis) in rats or rabbits, respectively (see Data ). The estimated background risk of major birth defects and miscarriage for the indicated population 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 Labor and Delivery There are no adequate and well-controlled human studies that have investigated the effects of STRIVERDI RESPIMAT during labor and delivery. Because of the potential for beta-agonist interference with uterine contractility, use of STRIVERDI RESPIMAT during labor should be restricted to those patients in whom the benefits clearly outweigh the risks. Data Animal Data STRIVERDI RESPIMAT was not teratogenic in rats at inhalation doses approximately 2,731 times the MRHDID (on an AUC basis at a maternal inhalation dose of 1,054 mcg/kg/day). No significant effects occurred in rabbits at inhalation doses approximately 1,353 times the MRHDID in adults (on an AUC basis at a maternal inhalation dose of 974 mcg/kg/day). Placental transfer of olodaterol was observed in pregnant rats. Olodaterol has been shown to be teratogenic in New Zealand rabbits at inhalation doses approximately 7,130 times the MRHDID in adults (on an AUC basis at a maternal inhalation dose of 2,489 mcg/kg/day). STRIVERDI RESPIMAT exhibited the following fetal toxicities: enlarged or small heart atria or ventricles, eye abnormalities, and split or distorted sternum. 8.2 Lactation Risk Summary There are no available data on the presence of olodaterol in human milk, the effects on the breastfed infant, or the effects on milk production. Olodaterol, the active component of STRIVERDI RESPIMAT, and/or its metabolites are present in the milk of lactating rats, however, due to species-specific differences in lactation physiology, the clinical relevance of these data are not clear (see Data ) . The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for STRIVERDI RESPIMAT and any potential adverse effects on the breastfed child from STRIVERDI RESPIMAT or from the underlying maternal condition. Data The distribution of olodaterol into milk was investigated after a single intravenous administration of 0.4 μmol/kg to lactating rats. Olodaterol and/or its metabolites are present in the milk of lactating rats at concentrations above those in plasma. 8.4 Pediatric Use STRIVERDI RESPIMAT is not indicated for use in children. The safety and effectiveness of STRIVERDI RESPIMAT in the pediatric population have not been established. 8.5 Geriatric Use Based on available data, no adjustment of STRIVERDI RESPIMAT dosage in geriatric patients is necessary. Of the 876 patients who received STRIVERDI RESPIMAT at the recommended dose of 5 mcg once-daily in the clinical studies from the pooled 1-year database, 485 were less than or equal to 65 years of age and 391 (44.6%) were greater than 65 years of age. No overall differences in effectiveness were observed, and in the 1-year pooled data, the adverse drug reaction profiles were similar in the older population compared to the patient population overall. 8.6 Hepatic Impairment Subjects with mild and moderate hepatic impairment showed no changes in C max or AUC, nor did protein binding differ between mild and moderate hepatically impaired subjects and their healthy controls. A study in subjects with severe hepatic impairment was not performed. 8.7 Renal Impairment Subjects with severe renal impairment showed no clinically relevant changes in C max or AUC compared to their healthy controls.
