Olodaterol Respimat Inhalation Spray

STRIVERDI RESPIMAT Inhalation Spray is a long-acting beta 2 -adrenergic agonist (LABA) indicated for: The long-term, once-daily maintenance bronchodilator treatment of airflow obstruction in patients with chronic obstructive pulmonary disease (COPD), including chronic bronchitis and/or emphysema. ( 1.1 ) Important limitations: STRIVERDI RESPIMAT is NOT indicated to treat acute deterioration of COPD. ( 1.2 ) STRIVERDI RESPIMAT is NOT indicated to treat asthma. ( 1.2 )

1.1 Maintenance Treatment of COPD STRIVERDI RESPIMAT is a long-acting beta 2 -agonist indicated for long-term, once-daily maintenance bronchodilator treatment of airflow obstruction in patients with chronic obstructive pulmonary disease (COPD), including chronic bronchitis and/or emphysema.

1.2 Important Limitations of Use STRIVERDI RESPIMAT is not indicated to treat acute deteriorations of COPD [see Warnings and Precautions (5.2) ] . STRIVERDI RESPIMAT is not indicated to treat asthma. The safety and effectiveness of STRIVERDI RESPIMAT in asthma have not been established.

The recommended dosage of STRIVERDI RESPIMAT is two inhalations once-daily at the same time of the day. Do not use STRIVERDI RESPIMAT more than two inhalations every 24 hours. Prior to first use, the STRIVERDI RESPIMAT cartridge is inserted into the STRIVERDI RESPIMAT inhaler and the unit is primed. When using the unit 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) ] . No dosage adjustment is required for geriatric patients, patients with mild and moderate hepatic impairment, or renally-impaired patients. There are no data available for use of STRIVERDI RESPIMAT in severe hepatically impaired patients [see Clinical Pharmacology (12.3) ]. For oral inhalation only. Two inhalations of STRIVERDI RESPIMAT once-daily at the same time of day. ( 2 )

STRIVERDI RESPIMAT consists of a STRIVERDI RESPIMAT inhaler and an aluminum cylinder (STRIVERDI RESPIMAT cartridge) containing olodaterol (as the hydrochloride). The STRIVERDI RESPIMAT cartridge is intended for use with the STRIVERDI RESPIMAT inhaler only. Each actuation from the STRIVERDI RESPIMAT inhaler delivers 2.5 mcg olodaterol (equivalent to 2.736 mcg olodaterol hydrochloride) from the mouthpiece. Two actuations equal one dose. Inhalation spray: Each actuation from the mouthpiece delivers 2.5 mcg olodaterol (equivalent to 2.736 mcg olodaterol hydrochloride). Two actuations equal one dose. ( 3 )

Use of a LABA, including STRIVERDI RESPIMAT, without an inhaled corticosteroid is contraindicated in patients with asthma [see Warnings and Precautions (5.1) ] . STRIVERDI RESPIMAT is not indicated for the treatment of asthma. Use of a LABA, including STRIVERDI RESPIMAT, without an inhaled corticosteroid is contraindicated in patients with asthma. ( 4 )

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.

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 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.

The expected signs and symptoms with overdosage of STRIVERDI RESPIMAT are those of excessive beta-adrenergic stimulation and occurrence or exaggeration of any of the signs and symptoms, e.g., myocardial ischemia, angina pectoris, hypertension or hypotension, tachycardia, arrhythmias, palpitations, dizziness, nervousness, insomnia, anxiety, headache, tremor, dry mouth, muscle spasms, nausea, fatigue, malaise, hypokalemia, hyperglycemia, and metabolic acidosis. As with all inhaled sympathomimetic medications, cardiac arrest and even death may be associated with an overdose of STRIVERDI RESPIMAT. Treatment of overdosage consists of discontinuation of STRIVERDI RESPIMAT together with institution of appropriate symptomatic and supportive therapy. The judicious use of a cardioselective beta-receptor blocker may be considered, bearing in mind that such medication can produce bronchospasm. There is insufficient evidence to determine if dialysis is beneficial for overdosage of STRIVERDI RESPIMAT. Cardiac monitoring is recommended in cases of overdosage.

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.

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.

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

Olodaterol is a long-acting beta 2 -adrenergic agonist (LABA). The compound exerts its pharmacological effects by binding and activation of beta 2 -adrenoceptors after topical administration by inhalation. Activation of these receptors in the airways results in a stimulation of intracellular adenyl cyclase, an enzyme that mediates the synthesis of cyclic-3', 5' adenosine monophosphate (cAMP). Elevated levels of cAMP induce bronchodilation by relaxation of airway smooth muscle cells. In vitro studies have shown that olodaterol has 241-fold greater agonist activity at beta 2 -adrenoceptors compared to beta 1 -adrenoceptors and 2,299-fold greater agonist activity compared to beta 3 -adrenoceptors. The clinical significance of these findings is unknown. Beta-adrenoceptors are divided into three subtypes: beta 1 -adrenoceptors predominantly expressed on cardiac smooth muscle, beta 2 -adrenoceptors predominantly expressed on airway smooth muscle, and beta 3 -adrenoceptors predominantly expressed on adipose tissue. Beta 2 -agonists cause bronchodilation. Although the beta 2 -adrenoceptor is the predominant adrenergic receptor in the airway smooth muscle, it is also present on the surface of a variety of other cells, including lung epithelial and endothelial cells and in the heart. The precise function of beta 2 -receptors in the heart is not known, but their presence raises the possibility that even highly selective beta 2 -agonists may have cardiac effects.

Systemic Safety The major adverse effects of inhaled beta 2 -adrenergic agonists occur as a result of excessive activation of systemic beta-adrenergic receptors. The most common adverse effects in adults include skeletal muscle tremor and cramps, insomnia, tachycardia, decreases in serum potassium, and increases in plasma glucose. Changes in serum potassium were evaluated in COPD patients in double-blind phase 3 studies. In pooled data, at the recommended 5 mcg dose there was no clinically relevant change compared to placebo in serum potassium. Cardiac Electrophysiology The effect of STRIVERDI RESPIMAT on the QT/QTc interval of the ECG was investigated in 24 healthy male and female volunteers in a double-blind, randomized, placebo- and active (moxifloxacin)- controlled study at single doses of 10, 20, 30, and 50 mcg. Dose-dependent QTcI (individual subject corrected QT interval) prolongation was observed. The maximum mean (one-sided 95% upper confidence bound) difference in QTcI from placebo after baseline correction was 2.5 (5.6) ms, 6.1 (9.2) ms, 7.5 (10.7) ms and 8.5 (11.6) ms following doses of 10, 20, 30 and 50 mcg, respectively. The effect of 5 mcg and 10 mcg STRIVERDI RESPIMAT on heart rate and rhythm was assessed using continuous 24-hour ECG recording (Holter monitoring) in a subset of 772 patients in the 48-week, placebo-controlled phase 3 trials. There were no dose- or time-related trends or patterns observed for the magnitudes of mean changes in heart rate or premature beats. Shifts from baseline to the end of treatment in premature beats did not indicate meaningful differences between STRIVERDI RESPIMAT 5 mcg, 10 mcg, and placebo.

Olodaterol showed linear pharmacokinetics. On repeated once-daily inhalation steady-state of olodaterol plasma concentrations was achieved after 8 days, and the extent of exposure was increased up to 1.8-fold as compared to a single dose. Absorption Olodaterol reaches maximum plasma concentrations generally within 10 to 20 minutes following drug inhalation. In healthy volunteers, the absolute bioavailability of olodaterol following inhalation was estimated to be approximately 30%, whereas the absolute bioavailability was below 1% when given as an oral solution. Thus, the systemic availability of olodaterol after inhalation is mainly determined by lung absorption, while any swallowed portion of the dose only negligibly contributes to systemic exposure. Distribution Olodaterol exhibits multi-compartmental disposition kinetics after inhalation as well as after intravenous administration. The volume of distribution is high (1,110 L), suggesting extensive distribution into tissue. In vitro binding of [ 14 C] olodaterol to human plasma proteins is independent of concentration and is approximately 60%. Elimination Total clearance of olodaterol in healthy volunteers is 872 mL/min, and renal clearance is 173 mL/min. The terminal half-life following intravenous administration is 22 hours. The terminal half-life following inhalation in contrast is about 45 hours, indicating that the latter is determined by absorption rather than by elimination processes. However, the effective half-life at daily dose of 5 mcg calculated from C max from COPD patients is 7.5 hours. Metabolism Olodaterol is substantially metabolized by direct glucuronidation and by O-demethylation at the methoxy moiety followed by conjugation. Of the six metabolites identified, only the unconjugated demethylation product binds to beta 2 -receptors. This metabolite, however, is not detectable in plasma after chronic inhalation of the recommended therapeutic dose. Cytochrome P450 isozymes CYP2C9 and CYP2C8, with negligible contribution of CYP3A4, are involved in the O-demethylation of olodaterol, while uridine diphosphate glycosyl transferase isoforms UGT2B7, UGT1A1, 1A7, and 1A9 were shown to be involved in the formation of olodaterol glucuronides. Excretion Following intravenous administration of [ 14 C]-labeled olodaterol, 38% of the radioactive dose was recovered in the urine and 53% was recovered in feces. The amount of unchanged olodaterol recovered in the urine after intravenous administration was 19%. Following oral administration, only 9% of olodaterol and/or its metabolites was recovered in urine, while the major portion was recovered in feces (84%). More than 90% of the dose was excreted within 6 and 5 days following intravenous and oral administration, respectively. Following inhalation, excretion of unchanged olodaterol in urine within the dosing interval in healthy volunteers at steady state accounted for 5% to 7% of the dose. Specific Populations A pharmacokinetic meta-analysis showed that no dose adjustment is necessary based on the effect of age, gender, and weight on systemic exposure in COPD patients after inhalation of STRIVERDI RESPIMAT. Patients with Renal Impairment Olodaterol levels were increased by approximately 40% in subjects with severe renal impairment. A study in subjects with mild and moderate renal impairment was not performed. Patients with 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. Drug Interaction Studies Drug interaction studies were carried out using fluconazole as a model inhibitor of CYP 2C9 and ketoconazole as a potent P-gp (and CYP3A4, 2C8, 2C9) inhibitor. Fluconazole: Co-administration of 400 mg fluconazole once a day for 14 days had no relevant effect on systemic exposure to olodaterol. Ketoconazole: Co-administration of 400 mg ketoconazole once a day for 14 days increased olodaterol C max by 66% and AUC 0-1 by 68%. Tiotropium: Co-administration of tiotropium bromide, delivered as fixed-dose combination with olodaterol, for 21 days had no relevant effect on systemic exposure to olodaterol, and vice versa.

, Mutagenesis, Impairment of Fertility Two-year inhalation studies were conducted in rats and mice to assess the carcinogenic potential of olodaterol. Lifetime treatment of female rats induced leiomyomas of the mesovarium at doses of 25.8 and 270 mcg/kg/day (approximately 18- and 198-fold, respectively, the MRHDID on an AUC basis). No tumor findings were observed in male rats at doses up to 270 mcg/kg/day (approximately 230-fold the MRHDID on an AUC basis). Lifetime treatment of female mice induced leiomyomas and leiomyosarcomas of the uterus at doses ≥76.9 mcg/kg/day (approximately 106-fold the MRHDID on an AUC basis). No tumor findings were observed in male mice at doses up to 255 mcg/kg/day (approximately 455-fold the MRHDID on an AUC basis). Increases in leiomyomas and leiomyosarcomas of the female rodent reproductive tract have been similarly demonstrated with other β 2 -adrenergic agonist drugs. The relevance of these findings to human use is unknown. Olodaterol was not mutagenic in the in vitro Ames test or in the in vitro mouse lymphoma assay. Olodaterol produced increased frequency of micronuclei in rats after intravenous doses. The increased frequency of micronuclei was likely related to drug enhanced (compensatory) erythropoiesis. The mechanism for induction of micronuclei formation is likely not relevant at clinical exposures. Olodaterol did not impair male or female fertility in rats at inhalation doses up to 3,068 mcg/kg/day (approximately 2,322 times the MRHDID on an AUC basis).

17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling (Patient Information and Instructions for Use). Serious Asthma-Related Events Inform patients that LABA, such as STRIVERDI RESPIMAT, when used as monotherapy [without an inhaled corticosteroid], increase the risk of serious asthma-related events, including asthma-related death. STRIVERDI RESPIMAT is not indicated for the treatment of asthma. Not for Acute Symptoms STRIVERDI RESPIMAT is not meant to relieve acute asthma symptoms or exacerbations of COPD and extra doses should not be used for that purpose. Acute symptoms should be treated with an inhaled, short-acting beta 2 -agonist such as albuterol. (The healthcare provider should provide the patient with such medication and instruct the patient in how it should be used.) Instruct patients to notify their physician immediately if they experience any of the following: Worsening of symptoms Decreasing effectiveness of inhaled, short-acting beta 2 -agonists Need for more inhalations than usual of inhaled, short-acting beta 2 -agonists Significant decrease in lung function as outlined by the physician Instruct patients not to stop therapy with STRIVERDI RESPIMAT without physician/provider guidance since symptoms may recur after discontinuation. Do Not Use Additional Long-Acting Beta 2 -Agonists Patients who have been taking inhaled, short-acting beta 2 -agonists on a regular basis should be instructed to discontinue the regular use of these products and use them only for the symptomatic relief of acute symptoms. When patients are prescribed STRIVERDI RESPIMAT, other inhaled medications containing long-acting beta 2 -agonists should not be used. Patients should not use more than the recommended once-daily dosage of STRIVERDI RESPIMAT. Excessive use of sympathomimetics may cause significant cardiovascular effects, and may be fatal. Risks Associated with Beta 2 -Agonist Therapy Inform patients of adverse effects associated with beta 2 -agonists, such as palpitations, chest pain, rapid heart rate, tremor, or nervousness. Paradoxical Bronchospasm Inform patients that STRIVERDI RESPIMAT can produce paradoxical bronchospasm. Advise patients that if paradoxical bronchospasm occurs, patients should discontinue STRIVERDI RESPIMAT. Hypersensitivity Reactions Inform patients that immediate hypersensitivity reactions, including angioedema, may occur after administration of STRIVERDI RESPIMAT. Advise patient to immediately discontinue STRIVERDI RESPIMAT and consult a physician. Instructions for Administering STRIVERDI RESPIMAT It is important for patients to understand how to correctly administer STRIVERDI RESPIMAT inhalation spray using the STRIVERDI RESPIMAT inhaler. Instruct patients that STRIVERDI RESPIMAT inhalation spray should only be administered via the STRIVERDI RESPIMAT inhaler and the STRIVERDI RESPIMAT inhaler should not be used for administering other medications. Instruct patients that priming STRIVERDI RESPIMAT is essential to ensure appropriate content of the medication in each actuation. When using the unit for the first time, the STRIVERDI RESPIMAT cartridge is inserted into the STRIVERDI RESPIMAT inhaler and the unit is primed. STRIVERDI RESPIMAT 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.
