In two placebo-controlled, 12-week, clinical studies (Trials 1 and 2) [see Clinical Studies ( 14 )] , a total of 1,364 adolescent and adult patients with persistent symptomatic asthma despite ICS or ICS/LABA therapy were treated twice daily with either placebo; fluticasone propionate MDPI 55 mcg, 113 mcg, 232 mcg; or fluticasone propionate/salmeterol MDPI 55 mcg/14 mcg, 113 mcg/14 mcg, 232 mcg/14 mcg. Sixty percent of patients were female and 80% of patients were white. The average duration of exposure was 82 to 84 days in the fluticasone propionate MDPI and fluticasone propionate/salmeterol MDPI treatment groups compared with 75 days in the placebo group. Table 2 displays the incidence of most common adverse reactions in pooled Trials 1 and 2.

Long Term Safety Study: This was a 26-week, open labeled study of 674 patients previously treated with ICS who were treated twice daily with fluticasone propionate MDPI 113 mcg or 232 mcg; fluticasone propionate/salmeterol MDPI 113 mcg/14 mcg or 232 mcg/14 mcg; fluticasone propionate inhalation aerosol 110 mcg or 220 mcg; fluticasone propionate and salmeterol inhalation powder (250 mcg/50 mcg), or fluticasone propionate and salmeterol inhalation powder (500 mcg/50 mcg). The types of adverse reactions were similar to those reported above in placebo controlled studies. 6.2 Postmarketing Experience In addition to adverse reactions reported from clinical trials, the following adverse reactions have been identified during post approval use of fluticasone propionate and/or salmeterol regardless of indication. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. These events have been chosen for inclusion due to either their seriousness, frequency of reporting, or causal connection to fluticasone propionate and/or salmeterol or a combination of these factors. Cardiac Disorders : Arrhythmias (including atrial fibrillation, extrasystoles, supraventricular tachycardia), ventricular tachycardia. Endocrine Disorders : Cushing’s syndrome, Cushingoid features, growth velocity reduction in children/adolescents, hypercorticism. Eye Disorders : Glaucoma, blurred vision and central serous chorioretinopathy. Gastrointestinal Disorders : Abdominal pain, dyspepsia, xerostomia. Immune System Disorders : Immediate and delayed hypersensitivity reaction (including very rare anaphylactic reaction). Very rare anaphylactic reaction in patients with severe milk protein allergy. Infections and Infestations : Esophageal candidiasis. Metabolic and Nutrition Disorders : Hyperglycemia, weight gain. Musculoskeletal, Connective Tissue, and Bone Disorders : Arthralgia, cramps, myositis, osteoporosis. Nervous System Disorders : Paresthesia, restlessness. Psychiatric Disorders : Agitation, aggression, depression. Behavioral changes, including hyperactivity and irritability, have been reported very rarely and primarily in children. Reproductive System and Breast Disorders : Dysmenorrhea. Respiratory, Thoracic, and Mediastinal Disorders : Chest congestion; chest tightness, dyspnea; facial and oropharyngeal edema, immediate bronchospasm; paradoxical bronchospasm; tracheitis; wheezing; reports of upper respiratory symptoms of laryngeal spasm, irritation, or swelling such as stridor or choking. Skin and Subcutaneous Tissue Disorders : Ecchymoses, photodermatitis. Vascular Disorders : Pallor.

Description

11 DESCRIPTION Fluticasone Propionate/Salmeterol MDPI 55 mcg/14 mcg, 113 mcg/14 mcg and 232 mcg/14 mcg are combinations of fluticasone propionate and salmeterol. Fluticasone Propionate One active component of this product is fluticasone propionate, a corticosteroid having the chemical name S -(fluoromethyl) 6α,9-difluoro-11ß,17-dihydroxy-16α-methyl-3-oxoandrosta-1,4-diene-17ß-carbothioate, 17-propionate, and the following chemical structure: Fluticasone propionate is a white powder with a molecular weight of 500.6, and the empirical formula is C 25 H 31 F 3 O 5 S. It is practically insoluble in water, freely soluble in dimethyl sulfoxide and dimethylformamide, and slightly soluble in methanol and 95% ethanol. Salmeterol Xinafoate The other active component of this product is salmeterol xinafoate, a beta 2 –adrenergic bronchodilator. Salmeterol xinafoate is the racemic form of the 1‑hydroxy‑2‑naphthoic acid salt of salmeterol. It has the chemical name 4-hydroxy-α -[[[6-(4-phenylbutoxy)hexyl]amino]methyl]-1,3-benzenedimethanol, 1-hydroxy-2-naphthalenecarboxylate and the following chemical structure: Salmeterol xinafoate is a white powder with a molecular weight of 603.8, and the empirical formula is C 25 H 37 NO 4 •C 11 H 8 O 3 . It is freely soluble in methanol; slightly soluble in ethanol, chloroform, and isopropanol; and sparingly soluble in water. Fluticasone Propionate/Salmeterol MDPI Fluticasone Propionate/Salmeterol MDPI is a multidose dry powder inhaler (MDPI) for oral inhalation only. It contains fluticasone propionate, salmeterol xinafoate, and lactose monohydrate (which may contain milk proteins). The opening of the mouthpiece cover meters 5.5 mg of the formulation from the device reservoir, which contains 55 mcg, 113 mcg, or 232 mcg of fluticasone propionate, and 14 mcg of salmeterol base (equivalent to 20.3 mcg of salmeterol xinafoate). Patient inhalation through the mouthpiece causes the deagglomeration and aerosolization of the drug particles as the formulation moves through the cyclone component of the device. This is followed by dispersion into the airstream. Under standardized in vitro test conditions, the Fluticasone Propionate/Salmeterol MDPI delivers 49 mcg, 100 mcg, or 202 mcg of fluticasone propionate and 12.75 mcg of salmeterol base (equivalent to 18.5 mcg of salmeterol xinafoate), with lactose from the mouthpiece when tested at a flow rate of 85 L/min for 1.4 seconds. The amount of drug delivered to the lung will depend on patient factors such as inspiratory flow profiles. In adult subjects (N=50, aged 18 to 45 years) with asthma, mean peak inspiratory flow (PIF) through the Fluticasone Propionate/Salmeterol MDPI was 108.28 L/min (range: 70.37 to 129.24 L/min). In adolescent subjects (N=50, aged 12 to 17 years) with asthma, mean peak inspiratory flow (PIF) through the Fluticasone Propionate/Salmeterol MDPI was 106.72 L/min (range: 73.64 to 125.51 L/min).

Dosage And Administration

2 DOSAGE AND ADMINISTRATION For oral inhalation only. ( 2.1 ) Starting dosage is based on prior asthma therapy and disease severity. ( 2.2 ) 1 inhalation of Fluticasone Propionate/Salmeterol 55 mcg/14 mcg, 113 mcg/14 mcg, or 232 mcg/14 mcg twice daily. ( 2.2 ) Do not use with a spacer or volume holding chamber. ( 2.2 ) 2.1 Administration Instructions Fluticasone Propionate/Salmeterol MDPI is for oral inhalation and does not require priming. Do not use Fluticasone Propionate/Salmeterol MDPI with a spacer or volume holding chamber. Do not use more than two times every 24 hours. More frequent administration or a greater number of daily inhalations (more than one inhalation twice daily) is not recommended as some patients are more likely to experience adverse reactions with higher salmeterol dosages. Avoid the concomitant use of other long acting beta 2 -adrenergic agonist (LABAs) [see Warnings and Precautions ( 5.3 , 5.11 )]. If asthma symptoms arise in the period between doses, an inhaled, short-acting beta 2 -agonist should be taken for immediate relief. 2.2 Recommended Dosage Administer 1 inhalation of Fluticasone Propionate/Salmeterol MDPI twice daily by oral inhalation (approximately 12 hours apart at the same time every day). Rinse the mouth with water without swallowing after each inhalation. Dosage Selection The recommended starting dosage for Fluticasone Propionate/Salmeterol MDPI is based on asthma severity and current inhaled corticosteroid use and strength. Patients not taking inhaled corticosteroids (ICS) (with less severe asthma): 1 inhalation of 55 mcg/14 mcg Fluticasone Propionate/Salmeterol MDPI dose strength (55 mcg of fluticasone propionate and 14 mcg of salmeterol), twice daily by oral inhalation. Patients with greater asthma severity, use the higher dose strengths: 1 inhalation of 113 mcg/14 mcg Fluticasone Propionate/Salmeterol MDPI (113 mcg of fluticasone propionate and 14 mcg of salmeterol) twice daily; or 1 inhalation of 232 mcg/14 mcg Fluticasone Propionate/Salmeterol MDPI (232 mcg of fluticasone propionate and 14 mcg of salmeterol) twice daily Patients switching to Fluticasone Propionate/Salmeterol MDPI from another inhaled corticosteroid or combination product: 1 inhalation of low (55 mcg/14 mcg), medium (113 mcg/14 mcg) or high (232 mcg/14 mcg) Fluticasone Propionate/Salmeterol MDPI twice daily by oral inhalation based on the strength of the previous inhaled corticosteroid product, or the strength of the inhaled corticosteroid from a combination product, and disease severity. The maximum recommended dosage of Fluticasone Propionate/Salmeterol MDPI is 232 mcg/14 mcg twice daily. General Dosing Information Improvement in asthma control following Fluticasone Propionate/Salmeterol MDPI administration can occur within 15 minutes of beginning treatment; although maximum benefit may not be achieved for 1 week or longer after starting treatment. Individual patients will experience a variable time to onset and degree of symptom relief. For patients who do not respond adequately to the starting dose of Fluticasone Propionate/Salmeterol MDPI after 2 weeks of therapy, consider increasing the strength (replace with higher strength) to possibly provide additional improvement in asthma control. If a previously effective dosage regimen fails to provide adequate improvement in asthma control, re-evaluate the therapeutic regimen, including patient compliance and inhaler technique, and consider additional therapeutic options (e.g., increasing the dose of Fluticasone Propionate/Salmeterol MDPI with a higher strength, adding additional controller therapies). After asthma stability has been achieved, it is desirable to titrate to the lowest effective dosage to reduce the risk of adverse reactions. 2.3 Storing and Cleaning the Inhaler Keep the inhaler in a cool dry place. Routine maintenance is not required. If the mouthpiece needs cleaning, gently wipe the mouthpiece with a dry cloth or tissue as needed. Never wash or put any part of the inhaler in water. 2.4 Dose Counter The Fluticasone Propionate/Salmeterol MDPI has a dose counter: The number 60 is displayed (prior to use). The dose counter will count down each time the mouthpiece is opened and closed [see Patient Counseling Information ( 17 )].

Indications And Usage

1 INDICATIONS AND USAGE Fluticasone Propionate/Salmeterol Multidose Dry Powder Inhaler (FS MDPI) is indicated for the treatment of asthma in adult and pediatric patients aged 12 years and older. Fluticasone Propionate/Salmeterol MDPI should be used for patients not adequately controlled on a long term asthma control medication such as an inhaled corticosteroid or whose disease warrants initiation of treatment with both an inhaled corticosteroid and long acting beta 2 -adrenergic agonist (LABA). Limitations of Use : Fluticasone Propionate/Salmeterol MDPI is not indicated for the relief of acute bronchospasm. Fluticasone Propionate/Salmeterol Multi-Dose Dry Powder Inhaler (MDPI) is a combination of fluticasone propionate, a corticosteroid, and salmeterol, a long-acting beta 2 -adrenergic agonist (LABA), indicated for treatment of asthma in adult and pediatric patients aged 12 years and older. Fluticasone Propionate/Salmeterol inhalation powder should be used for patients not adequately controlled on a long term asthma control medication such as an inhaled corticosteroid or whose disease warrants initiation of treatment with both an inhaled corticosteroid and long acting beta 2 -adrenergic agonist (LABA). ( 1 ) Limitations of Use : Not indicated for the relief of acute bronchospasm. ( 1 )

Overdosage

10 OVERDOSAGE This product contains both fluticasone propionate and salmeterol; therefore, the risks associated with overdosage for the individual components described below apply to Fluticasone Propionate/Salmeterol MDPI. Treatment of overdosage consists of discontinuation of Fluticasone Propionate/Salmeterol MDPI 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 cases of overdosage. Fluticasone propionate Chronic overdosage of fluticasone propionate may result in signs/symptoms of hypercorticism [see Warnings and Precautions ( 5.7 )] . Salmeterol The expected signs and symptoms with overdosage of salmeterol 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). Overdosage with salmeterol can lead to clinically significant prolongation of the QTc interval, which can produce ventricular arrhythmias. As with all inhaled sympathomimetic medicines, cardiac arrest and even death may be associated with an overdose of salmeterol.

Drug Interactions

7 DRUG INTERACTIONS Fluticasone Propionate/Salmeterol MDPI has been used concomitantly with other drugs, including short‑acting beta 2 ‑agonists, and intranasal corticosteroids, commonly used in patients with asthma without adverse drug reactions [see Clinical Pharmacology ( 12.2 )] . No formal drug interaction trials have been performed with Fluticasone Propionate/Salmeterol MDPI. Avoid strong cytochrome P450 3A4 inhibitors (e.g., ritonavir, ketoconazole): May increase risk of systemic corticosteroid and cardiovascular effects. ( 7.1 ) Monoamine oxidase inhibitors and tricyclic antidepressants: Use with extreme caution. May potentiate effect of salmeterol on vascular system. ( 7.2 ) Beta‑blockers: Use with caution. May block bronchodilatory effects of beta‑agonists and produce severe bronchospasm. ( 7.3 ) Diuretics: Use with caution. Electrocardiographic changes and/or hypokalemia associated with non‑potassium‑sparing diuretics may worsen with concomitant beta‑agonists. ( 7.4 ) 7.1 Inhibitors of Cytochrome P450 3A4 Fluticasone propionate and salmeterol, the individual components of this product, are substrates of CYP3A4. The use of strong CYP3A4 inhibitors (e.g., ritonavir, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, saquinavir, ketoconazole, telithromycin) with Fluticasone Propionate/Salmeterol MDPI is not recommended because increased systemic corticosteroid and increased cardiovascular adverse effects may occur. Ritonavir : Fluticasone Propionate: A drug interaction trial with fluticasone propionate aqueous nasal spray in healthy subjects has shown that ritonavir (a strong CYP3A4 inhibitor) can significantly increase plasma fluticasone propionate exposure, resulting in significantly reduced serum cortisol concentrations [see Clinical Pharmacology (12.3)] . During postmarketing use, there have been reports of clinically significant drug interactions in patients receiving fluticasone propionate and ritonavir, resulting in systemic corticosteroid effects including Cushing’s syndrome and adrenal suppression. Ketoconazole : Fluticasone Propionate: Coadministration of orally inhaled fluticasone propionate (1,000 mcg) and ketoconazole (200 mg once daily) resulted in a 1.9‑fold increase in plasma fluticasone propionate exposure and a 45% decrease in plasma cortisol area under the curve (AUC) but had no effect on urinary excretion of cortisol. Salmeterol: In a drug interaction trial in 20 healthy subjects, coadministration of inhaled salmeterol (50 mcg twice daily) and oral ketoconazole (400 mg once daily) for 7 days resulted in greater systemic exposure to salmeterol (AUC increased 16‑fold and C max increased 1.4‑fold). Three (3) subjects were withdrawn due to beta 2 ‑agonist side effects (2 with prolonged QTc and 1 with palpitations and sinus tachycardia). Although there was no statistical effect on the mean QTc, coadministration of salmeterol and ketoconazole was associated with more frequent increases in QTc duration compared with salmeterol and placebo administration [see Clinical Pharmacology ( 12.3 )] . 7.2 Monoamine Oxidase Inhibitors and Tricyclic Antidepressants Fluticasone Propionate/Salmeterol MDPI should be administered with extreme caution to patients being treated with monoamine oxidase inhibitors or tricyclic antidepressants, or within 2 weeks of discontinuation of such agents, because the action of salmeterol, a component of this product, on the vascular system may be potentiated by these agents. 7.3 Beta-Adrenergic Receptor Blocking Agents Beta‑blockers not only block the pulmonary effect of beta‑agonists, such as salmeterol, a component of this product, but may also produce severe bronchospasm in patients with asthma. Therefore, patients with asthma should not normally be treated with beta‑blockers. However, under certain circumstances, there may be no acceptable alternatives to the use of beta‑adrenergic blocking agents for these patients; cardioselective beta‑blockers could be considered, although they should be administered with caution. 7.4 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, such as salmeterol, a component of this product, especially when the recommended dose of the beta‑agonist is exceeded. Although the clinical significance of these effects is not known, caution is advised in the coadministration of Fluticasone Propionate/Salmeterol MDPI with non-potassium‑sparing diuretics.

Clinical Pharmacology

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action This product contains both fluticasone propionate and salmeterol. The mechanisms of action described below for the individual components apply to this combination product. These drugs represent 2 different classes of medications (a synthetic corticosteroid and a LABA) that have different effects on clinical, physiologic, and inflammatory indices. Fluticasone Propionate : Fluticasone propionate is a synthetic trifluorinated corticosteroid with anti-inflammatory activity. Fluticasone propionate has been shown in vitro to exhibit a binding affinity for the human glucocorticoid receptor that is 18 times that of dexamethasone, almost twice that of beclomethasone-17-monopropionate (BMP), the active metabolite of beclomethasone dipropionate, and over 3 times that of budesonide. Data from the McKenzie vasoconstrictor assay in humans are consistent with these results. The clinical significance of these findings is unknown. Inflammation is an important component in the pathogenesis of asthma. Corticosteroids have been shown to have a wide range of actions on multiple cell types (e.g., mast cells, eosinophils, neutrophils, macrophages, and lymphocytes) and mediators (e.g., histamine, eicosanoids, leukotrienes, and cytokines) involved in inflammation. These anti-inflammatory actions of corticosteroids contribute to their efficacy in the treatment of asthma. Salmeterol : Salmeterol is a selective LABA. In vitro studies show salmeterol to be at least 50 times more selective for beta 2 ‑adrenoceptors than albuterol. Although beta 2 ‑adrenoceptors are the predominant adrenergic receptors in bronchial smooth muscle and beta 1 ‑adrenoceptors are the predominant receptors in the heart, there are also beta 2 ‑adrenoceptors in the human heart comprising 10% to 50% of the total beta‑adrenoceptors. The precise function of these receptors has not been established, but their presence raises the possibility that even selective beta 2 ‑agonists may have cardiac effects. The pharmacologic effects of beta 2 ‑adrenoceptor agonist drugs, including salmeterol, 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. In vitro tests show that salmeterol is a potent and long‑lasting inhibitor of the release of mast cell mediators, such as histamine, leukotrienes, and prostaglandin D 2 , from human lung. Salmeterol inhibits histamine‑induced plasma protein extravasation and inhibits platelet‑activating factor‑induced eosinophil accumulation in the lungs of guinea pigs when administered by the inhaled route. In humans, single doses of salmeterol administered via inhalation aerosol attenuate allergen‑induced bronchial hyperresponsiveness. 12.2 Pharmacodynamics Hypothalamic Pituitary Adrenal Axis Effects (HPA) There are no HPA data from controlled trials of the Fluticasone Propionate/Salmeterol MDPI in healthy subjects or subjects with asthma. Cardiovascular Effects and Effects on Potassium and Glucose Fluticasone Propionate/Salmeterol MDPI in Healthy Subjects There were no clinical trials conducted with Fluticasone Propionate/Salmeterol MDPI that assessed cardiovascular (CV) effects in healthy subjects. Other Fluticasone Propionate and Salmeterol Dry Powder Inhaler (DPI) Products in Healthy Subjects Since systemic pharmacodynamic effects of salmeterol are not normally seen at the maximum approved salmeterol dosage, higher doses were used to produce measurable effects. Four trials were conducted with healthy adult subjects to assess CV effects: Single‑dose crossover trial using 2 inhalations of fluticasone propionate and salmeterol DPI (500 mcg/50 mcg) (two times the maximum approved salmeterol dosage for that DPI per dosing interval), fluticasone propionate DPI 500 mcg and salmeterol DPI 50 mcg given concurrently, or fluticasone propionate DPI 500 mcg given alone, Cumulative dose trial using 50 to 400 mcg of salmeterol DPI (1 time to 8 times the maximum approved salmeterol dosage per dosing interval for that DPI, respectively) given alone, or fluticasone propionate and salmeterol DPI (500 mcg/50 mcg), Repeat‑dose trial for 11 days using 2 inhalations twice daily of fluticasone propionate and salmeterol DPI (250 mcg/50 mcg) (two times the maximum approved salmeterol dosage for that DPI per dosing interval), fluticasone propionate DPI 250 mcg, or salmeterol DPI 50 mcg, and Single-dose trial using 5 inhalations of fluticasone propionate and salmeterol DPI (100 mcg/50 mcg) (five times the maximum approved salmeterol dosage for that DPI per dosing interval), fluticasone propionate DPI 100 mcg alone, or placebo. In these trials, no significant differences were observed in the pharmacodynamic effects of salmeterol (pulse rate, blood pressure, QTc interval, potassium, and glucose) whether the salmeterol was given as fluticasone propionate and salmeterol DPI, concurrently with fluticasone propionate from separate inhalers, or as salmeterol alone. The systemic pharmacodynamic effects of salmeterol were not altered by the presence of fluticasone propionate in the fluticasone propionate and salmeterol DPI product. Other Salmeterol Products in Subjects with Asthma: Inhaled salmeterol, like other beta‑adrenergic agonist drugs, can produce dose‑related CV effects and effects on blood glucose and/or serum potassium [see Warnings and Precautions ( 5.11 , 5.17 )] . The CV effects (heart rate, blood pressure) associated with salmeterol inhalation aerosol occurred with similar frequency, and are of similar type and severity, as those noted following albuterol administration. The effects of rising inhaled doses of salmeterol and standard inhaled doses of albuterol were studied in volunteers and in subjects with asthma. Salmeterol doses up to 84 mcg administered as inhalation aerosol resulted in heart rate increases of 3 to 16 beats/minute, about the same as albuterol dosed at 180 mcg by inhalation aerosol (4 to 10 beats/minute). Adult and adolescent subjects receiving 50 mcg doses of salmeterol MDPI (N=60) underwent continuous electrocardiographic monitoring during two 12‑hour periods after the first dose and after 1 month of therapy, and no clinically significant dysrhythmias were noted. Concomitant Use of Fluticasone Propionate/Salmeterol MDPI With Other Respiratory Medications: Short-Acting Beta 2 ‑Agonists: In clinical trials in subjects with asthma, the mean daily need for albuterol by 166 adult and adolescent subjects aged 12 years and older using another fluticasone propionate/salmeterol DPI product was approximately 1.3 inhalations/day and ranged from 0 to 9 inhalations/day (0 to about 4.5 times the maximum approved salmeterol dosage for that DPI per dosing interval). Five percent (5%) of subjects using another fluticasone propionate/salmeterol DPI product in these trials averaged 6 or more inhalations per day (3 times the maximum approved salmeterol dosage for that DPI per dosing interval) over the course of the 12-week trials. No increase in frequency of CV adverse events was observed among subjects who averaged 6 or more inhalations per day. Methylxanthines: In clinical trials in subjects with asthma, 39 subjects receiving another fluticasone propionate/salmeterol MDPI product, fluticasone propionate 100 mcg and salmeterol 50 mcg, fluticasone propionate 250 mcg and salmeterol 50 mcg, or fluticasone propionate 500 mcg and salmeterol 50 mcg twice daily concurrently with a theophylline product had adverse event rates similar to those in 304 subjects receiving another fluticasone propionate/salmeterol product without theophylline. Similar results were observed in subjects receiving salmeterol 50 mcg plus fluticasone propionate 500 mcg twice daily concurrently with a theophylline product (n = 39) or without theophylline (n = 132). 12.3 Pharmacokinetics Absorption Fluticasone Propionate: Fluticasone Propionate/Salmeterol MDPI acts locally in the lung; therefore, plasma levels may not predict therapeutic effect. Trials using oral dosing of labeled and unlabeled drug have demonstrated that the oral systemic bioavailability of fluticasone propionate was negligible (<1%), primarily due to incomplete absorption and presystemic metabolism in the gut and liver. In contrast, the majority of the fluticasone propionate delivered to the lung was systemically absorbed. After administration of 232 mcg/14 mcg Fluticasone Propionate/Salmeterol MDPI to patients aged 12 years and older with persistent asthma in a clinical trial, the mean C max value of fluticasone propionate was 66 pg/mL with a median t max value of approximately 2 hours. Salmeterol: After administration of 232 mcg/14 mcg Fluticasone Propionate/Salmeterol MDPI to patients aged 12 years and older with persistent asthma, the mean C max values of salmeterol was 60 pg/mL. The median t max was 5 minutes. Distribution Fluticasone Propionate: Following intravenous administration, the initial disposition phase for fluticasone propionate was rapid and consistent with its high lipid solubility and tissue binding. The volume of distribution averaged 4.2 L/kg. The percentage of fluticasone propionate bound to human plasma proteins averages 99%. Fluticasone propionate is weakly and reversibly bound to erythrocytes and is not significantly bound to human transcortin. Salmeterol: Volume of distribution data are not available for salmeterol. The percentage of salmeterol bound to human plasma proteins averages 96% in vitro over the concentration range of 8 to 7,722 ng of salmeterol base per milliliter, much higher concentrations than those achieved following therapeutic doses of salmeterol. Elimination Fluticasone Propionate: Following intravenous dosing, fluticasone propionate showed polyexponential kinetics and had a terminal elimination half-life of approximately 7.8 hours. Terminal half-life estimates of fluticasone propionate following oral inhalation administration of Fluticasone Propionate/Salmeterol MDPI were approximately 10.8 hours. Metabolism The total clearance of fluticasone propionate is high (average, 1,093 mL/minute), with renal clearance accounting for less than 0.02% of the total. The only circulating metabolite detected in humans is the 17β carboxylic acid derivative of fluticasone propionate, which is formed through the CYP3A4 pathway. This metabolite has less affinity (approximately 1/2,000) than the parent drug for the glucocorticoid receptor of human lung cytosol in vitro and negligible pharmacological activity in animal studies. Other metabolites detected in vitro using cultured human hepatoma cells have not been detected in humans. Excretion Less than 5% of a radiolabeled oral dose was excreted in the urine as metabolites, with the remainder excreted in the feces as parent drug and metabolites. Salmeterol : Terminal half-life estimates for salmeterol for Fluticasone Propionate/Salmeterol MDPI were approximately 12.6 hours. The xinafoate moiety has no apparent pharmacologic activity. The xinafoate moiety is highly protein bound (greater than 99%) and has a long elimination half-life of 11 days. Metabolism Salmeterol base is extensively metabolized by hydroxylation. An in vitro study using human liver microsomes showed that salmeterol is extensively metabolized to α hydroxysalmeterol (aliphatic oxidation) by CYP3A4. Ketoconazole, a strong inhibitor of CYP3A4, essentially completely inhibited the formation of α hydroxysalmeterol in vitro. Excretion In 2 healthy adult subjects who received 1 mg of radiolabeled salmeterol (as salmeterol xinafoate) orally, approximately 25% and 60% of the radiolabeled salmeterol was eliminated in urine and feces, respectively, over a period of 7 days. Specific Populations A population pharmacokinetic analysis was performed for fluticasone propionate and salmeterol utilizing data from 9 controlled clinical trials that included 350 subjects with asthma aged 4 to 77 years who received treatment with another fluticasone propionate and salmeterol MDPI product, the combination of HFA‑propelled fluticasone propionate and salmeterol inhalation aerosol, fluticasone propionate MDPI, HFA‑propelled fluticasone propionate inhalation aerosol, or CFC‑propelled fluticasone propionate inhalation aerosol. The population pharmacokinetic analyses for fluticasone propionate and salmeterol showed no clinically relevant effects of age, gender, race, body weight, body mass index, or percent of predicted FEV 1 on apparent clearance and apparent volume of distribution. Fluticasone Propionate/Salmeterol MDPI is not approved in pediatric patients younger than 12 years. Age: No pharmacokinetic studies have been performed with Fluticasone Propionate/Salmeterol MDPI in geriatric patients. Adolescents Aged 12 to 17 Years: A subgroup analysis was conducted to compare patients aged 12 to 17 (n=15) and ≥18 (n=23) years following administration of 232 mcg/14 mcg Fluticasone Propionate/Salmeterol MDPI. No overall differences in fluticasone propionate and salmeterol pharmacokinetics were observed. Male and Female Patients: A subgroup analysis was conducted to compare male (n=21) and female (n=16) adolescent and adult patients following administration of 232 mcg/14 mcg Fluticasone Propionate/Salmeterol MDPI. No overall differences in fluticasone propionate and salmeterol pharmacokinetics were observed. Patients with Renal Impairment : The effect of renal impairment of the pharmacokinetics of Fluticasone Propionate/Salmeterol MDPI has not been evaluated. Patients with Hepatic Impairment : Formal pharmacokinetic studies using Fluticasone Propionate/Salmeterol MDPI have not been conducted in patients with hepatic impairment. However, since both fluticasone propionate and salmeterol are predominantly cleared by hepatic metabolism, impairment of liver function may lead to accumulation of fluticasone propionate and salmeterol in plasma [see Use in Specific Populations ( 8.6 )] . Drug Interaction Studies In a single-dose trial, the presence of salmeterol did not alter fluticasone propionate exposure. No studies have been performed with Fluticasone Propionate/Salmeterol MDPI to investigate the effect of fluticasone propionate on salmeterol pharmacokinetics when given in combination. Drug Interaction Studies with Another Fluticasone Propionate/Salmeterol MDPI Product : The population pharmacokinetic analysis from 9 controlled clinical trials in 350 subjects with asthma showed no significant effects on fluticasone propionate or salmeterol pharmacokinetics following co-administration with beta 2 -agonists, corticosteroids, antihistamines, or theophyllines. Strong CYP3A4 Inhibitors: Fluticasone propionate is a substrate of CYP3A4. Coadministration of fluticasone propionate and ritonavir, a strong CYP3A4 inhibitor, is not recommended based upon a multiple-dose, crossover drug interaction trial in 18 healthy subjects [see Drug Interactions ( 7.1 )] . Plasma fluticasone propionate concentrations following fluticasone propionate aqueous nasal spray alone were undetectable (<10 pg/mL) in most subjects, and when concentrations were detectable, peak levels (C max ) averaged 11.9 pg/mL (range: 10.8 to 14.1 pg/mL) and AUC 0-τ averaged 8.43 pg•h/mL (range: 4.2 to 18.8 pg•h/mL). However, the fluticasone propionate C max and AUC 0-τ increased to 318 pg/mL (range: 110 to 648 pg/mL) and 3,102.6 pg•h/mL (range: 1,207.1 to 5,662.0 pg•h/mL), respectively, after 7 days of coadministration of ritonavir (100 mg twice daily) with fluticasone propionate aqueous nasal spray (200 mcg once daily). This significant increase in plasma fluticasone propionate exposure resulted in a significant decrease (86%) in serum cortisol AUC. Ketoconazole: In a placebo-controlled crossover trial in 8 healthy adult volunteers, coadministration of a single dose of orally inhaled fluticasone propionate (1,000 mcg) with multiple doses of ketoconazole (200 mg) to steady state resulted in increased plasma fluticasone propionate exposure, a reduction in plasma cortisol AUC, and no effect on urinary excretion of cortisol. In a placebo-controlled, crossover drug interaction trial in 20 healthy male and female subjects, coadministration of salmeterol (50 mcg twice daily) and ketoconazole, a strong CYP3A4 inhibitor, (400 mg once daily) for 7 days resulted in a significant increase in plasma salmeterol exposure as determined by a 16-fold increase in AUC (ratio with and without ketoconazole 15.76 [90% CI: 10.66, 23.31]) mainly due to increased bioavailability of the swallowed portion of the dose. Peak plasma salmeterol concentrations were increased by 1.4-fold (90% CI: 1.23, 1.68). Three (3) out of 20 subjects (15%) were withdrawn from salmeterol and ketoconazole coadministration due to beta-agonist-mediated systemic effects (2 with QTc prolongation and 1 with palpitations and sinus tachycardia). Coadministration of salmeterol and ketoconazole did not result in a clinically significant effect on mean heart rate, mean blood potassium, or mean blood glucose. Although there was no statistical effect on the mean QTc, coadministration of salmeterol and ketoconazole was associated with more frequent increases in QTc duration compared with salmeterol administration alone and placebo administration. Erythromycin: In a multiple-dose drug interaction trial, coadministration of orally inhaled fluticasone propionate (500 mcg twice daily) and erythromycin (333 mg 3 times daily) did not affect fluticasone propionate pharmacokinetics. In a repeat-dose trial in 13 healthy subjects, concomitant administration of erythromycin (a moderate CYP3A4 inhibitor) and salmeterol inhalation aerosol resulted in a 40% increase in salmeterol C max at steady state (ratio with and without erythromycin 1.4 [90% CI: 0.96, 2.03], P = 0.12), a 3.6-beat/min increase in heart rate ([95% CI: 0.19, 7.03], P<0.04), a 5.8-msec increase in QTc interval ([95% CI: -6.14, 17.77], P = 0.34), and no change in plasma potassium.

Mechanism Of Action

12.1 Mechanism of Action This product contains both fluticasone propionate and salmeterol. The mechanisms of action described below for the individual components apply to this combination product. These drugs represent 2 different classes of medications (a synthetic corticosteroid and a LABA) that have different effects on clinical, physiologic, and inflammatory indices. Fluticasone Propionate : Fluticasone propionate is a synthetic trifluorinated corticosteroid with anti-inflammatory activity. Fluticasone propionate has been shown in vitro to exhibit a binding affinity for the human glucocorticoid receptor that is 18 times that of dexamethasone, almost twice that of beclomethasone-17-monopropionate (BMP), the active metabolite of beclomethasone dipropionate, and over 3 times that of budesonide. Data from the McKenzie vasoconstrictor assay in humans are consistent with these results. The clinical significance of these findings is unknown. Inflammation is an important component in the pathogenesis of asthma. Corticosteroids have been shown to have a wide range of actions on multiple cell types (e.g., mast cells, eosinophils, neutrophils, macrophages, and lymphocytes) and mediators (e.g., histamine, eicosanoids, leukotrienes, and cytokines) involved in inflammation. These anti-inflammatory actions of corticosteroids contribute to their efficacy in the treatment of asthma. Salmeterol : Salmeterol is a selective LABA. In vitro studies show salmeterol to be at least 50 times more selective for beta 2 ‑adrenoceptors than albuterol. Although beta 2 ‑adrenoceptors are the predominant adrenergic receptors in bronchial smooth muscle and beta 1 ‑adrenoceptors are the predominant receptors in the heart, there are also beta 2 ‑adrenoceptors in the human heart comprising 10% to 50% of the total beta‑adrenoceptors. The precise function of these receptors has not been established, but their presence raises the possibility that even selective beta 2 ‑agonists may have cardiac effects. The pharmacologic effects of beta 2 ‑adrenoceptor agonist drugs, including salmeterol, 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. In vitro tests show that salmeterol is a potent and long‑lasting inhibitor of the release of mast cell mediators, such as histamine, leukotrienes, and prostaglandin D 2 , from human lung. Salmeterol inhibits histamine‑induced plasma protein extravasation and inhibits platelet‑activating factor‑induced eosinophil accumulation in the lungs of guinea pigs when administered by the inhaled route. In humans, single doses of salmeterol administered via inhalation aerosol attenuate allergen‑induced bronchial hyperresponsiveness.

Pharmacodynamics

12.2 Pharmacodynamics Hypothalamic Pituitary Adrenal Axis Effects (HPA) There are no HPA data from controlled trials of the Fluticasone Propionate/Salmeterol MDPI in healthy subjects or subjects with asthma. Cardiovascular Effects and Effects on Potassium and Glucose Fluticasone Propionate/Salmeterol MDPI in Healthy Subjects There were no clinical trials conducted with Fluticasone Propionate/Salmeterol MDPI that assessed cardiovascular (CV) effects in healthy subjects. Other Fluticasone Propionate and Salmeterol Dry Powder Inhaler (DPI) Products in Healthy Subjects Since systemic pharmacodynamic effects of salmeterol are not normally seen at the maximum approved salmeterol dosage, higher doses were used to produce measurable effects. Four trials were conducted with healthy adult subjects to assess CV effects: Single‑dose crossover trial using 2 inhalations of fluticasone propionate and salmeterol DPI (500 mcg/50 mcg) (two times the maximum approved salmeterol dosage for that DPI per dosing interval), fluticasone propionate DPI 500 mcg and salmeterol DPI 50 mcg given concurrently, or fluticasone propionate DPI 500 mcg given alone, Cumulative dose trial using 50 to 400 mcg of salmeterol DPI (1 time to 8 times the maximum approved salmeterol dosage per dosing interval for that DPI, respectively) given alone, or fluticasone propionate and salmeterol DPI (500 mcg/50 mcg), Repeat‑dose trial for 11 days using 2 inhalations twice daily of fluticasone propionate and salmeterol DPI (250 mcg/50 mcg) (two times the maximum approved salmeterol dosage for that DPI per dosing interval), fluticasone propionate DPI 250 mcg, or salmeterol DPI 50 mcg, and Single-dose trial using 5 inhalations of fluticasone propionate and salmeterol DPI (100 mcg/50 mcg) (five times the maximum approved salmeterol dosage for that DPI per dosing interval), fluticasone propionate DPI 100 mcg alone, or placebo. In these trials, no significant differences were observed in the pharmacodynamic effects of salmeterol (pulse rate, blood pressure, QTc interval, potassium, and glucose) whether the salmeterol was given as fluticasone propionate and salmeterol DPI, concurrently with fluticasone propionate from separate inhalers, or as salmeterol alone. The systemic pharmacodynamic effects of salmeterol were not altered by the presence of fluticasone propionate in the fluticasone propionate and salmeterol DPI product. Other Salmeterol Products in Subjects with Asthma: Inhaled salmeterol, like other beta‑adrenergic agonist drugs, can produce dose‑related CV effects and effects on blood glucose and/or serum potassium [see Warnings and Precautions ( 5.11 , 5.17 )] . The CV effects (heart rate, blood pressure) associated with salmeterol inhalation aerosol occurred with similar frequency, and are of similar type and severity, as those noted following albuterol administration. The effects of rising inhaled doses of salmeterol and standard inhaled doses of albuterol were studied in volunteers and in subjects with asthma. Salmeterol doses up to 84 mcg administered as inhalation aerosol resulted in heart rate increases of 3 to 16 beats/minute, about the same as albuterol dosed at 180 mcg by inhalation aerosol (4 to 10 beats/minute). Adult and adolescent subjects receiving 50 mcg doses of salmeterol MDPI (N=60) underwent continuous electrocardiographic monitoring during two 12‑hour periods after the first dose and after 1 month of therapy, and no clinically significant dysrhythmias were noted. Concomitant Use of Fluticasone Propionate/Salmeterol MDPI With Other Respiratory Medications: Short-Acting Beta 2 ‑Agonists: In clinical trials in subjects with asthma, the mean daily need for albuterol by 166 adult and adolescent subjects aged 12 years and older using another fluticasone propionate/salmeterol DPI product was approximately 1.3 inhalations/day and ranged from 0 to 9 inhalations/day (0 to about 4.5 times the maximum approved salmeterol dosage for that DPI per dosing interval). Five percent (5%) of subjects using another fluticasone propionate/salmeterol DPI product in these trials averaged 6 or more inhalations per day (3 times the maximum approved salmeterol dosage for that DPI per dosing interval) over the course of the 12-week trials. No increase in frequency of CV adverse events was observed among subjects who averaged 6 or more inhalations per day. Methylxanthines: In clinical trials in subjects with asthma, 39 subjects receiving another fluticasone propionate/salmeterol MDPI product, fluticasone propionate 100 mcg and salmeterol 50 mcg, fluticasone propionate 250 mcg and salmeterol 50 mcg, or fluticasone propionate 500 mcg and salmeterol 50 mcg twice daily concurrently with a theophylline product had adverse event rates similar to those in 304 subjects receiving another fluticasone propionate/salmeterol product without theophylline. Similar results were observed in subjects receiving salmeterol 50 mcg plus fluticasone propionate 500 mcg twice daily concurrently with a theophylline product (n = 39) or without theophylline (n = 132).

Pharmacokinetics

12.3 Pharmacokinetics Absorption Fluticasone Propionate: Fluticasone Propionate/Salmeterol MDPI acts locally in the lung; therefore, plasma levels may not predict therapeutic effect. Trials using oral dosing of labeled and unlabeled drug have demonstrated that the oral systemic bioavailability of fluticasone propionate was negligible (<1%), primarily due to incomplete absorption and presystemic metabolism in the gut and liver. In contrast, the majority of the fluticasone propionate delivered to the lung was systemically absorbed. After administration of 232 mcg/14 mcg Fluticasone Propionate/Salmeterol MDPI to patients aged 12 years and older with persistent asthma in a clinical trial, the mean C max value of fluticasone propionate was 66 pg/mL with a median t max value of approximately 2 hours. Salmeterol: After administration of 232 mcg/14 mcg Fluticasone Propionate/Salmeterol MDPI to patients aged 12 years and older with persistent asthma, the mean C max values of salmeterol was 60 pg/mL. The median t max was 5 minutes. Distribution Fluticasone Propionate: Following intravenous administration, the initial disposition phase for fluticasone propionate was rapid and consistent with its high lipid solubility and tissue binding. The volume of distribution averaged 4.2 L/kg. The percentage of fluticasone propionate bound to human plasma proteins averages 99%. Fluticasone propionate is weakly and reversibly bound to erythrocytes and is not significantly bound to human transcortin. Salmeterol: Volume of distribution data are not available for salmeterol. The percentage of salmeterol bound to human plasma proteins averages 96% in vitro over the concentration range of 8 to 7,722 ng of salmeterol base per milliliter, much higher concentrations than those achieved following therapeutic doses of salmeterol. Elimination Fluticasone Propionate: Following intravenous dosing, fluticasone propionate showed polyexponential kinetics and had a terminal elimination half-life of approximately 7.8 hours. Terminal half-life estimates of fluticasone propionate following oral inhalation administration of Fluticasone Propionate/Salmeterol MDPI were approximately 10.8 hours. Metabolism The total clearance of fluticasone propionate is high (average, 1,093 mL/minute), with renal clearance accounting for less than 0.02% of the total. The only circulating metabolite detected in humans is the 17β carboxylic acid derivative of fluticasone propionate, which is formed through the CYP3A4 pathway. This metabolite has less affinity (approximately 1/2,000) than the parent drug for the glucocorticoid receptor of human lung cytosol in vitro and negligible pharmacological activity in animal studies. Other metabolites detected in vitro using cultured human hepatoma cells have not been detected in humans. Excretion Less than 5% of a radiolabeled oral dose was excreted in the urine as metabolites, with the remainder excreted in the feces as parent drug and metabolites. Salmeterol : Terminal half-life estimates for salmeterol for Fluticasone Propionate/Salmeterol MDPI were approximately 12.6 hours. The xinafoate moiety has no apparent pharmacologic activity. The xinafoate moiety is highly protein bound (greater than 99%) and has a long elimination half-life of 11 days. Metabolism Salmeterol base is extensively metabolized by hydroxylation. An in vitro study using human liver microsomes showed that salmeterol is extensively metabolized to α hydroxysalmeterol (aliphatic oxidation) by CYP3A4. Ketoconazole, a strong inhibitor of CYP3A4, essentially completely inhibited the formation of α hydroxysalmeterol in vitro. Excretion In 2 healthy adult subjects who received 1 mg of radiolabeled salmeterol (as salmeterol xinafoate) orally, approximately 25% and 60% of the radiolabeled salmeterol was eliminated in urine and feces, respectively, over a period of 7 days. Specific Populations A population pharmacokinetic analysis was performed for fluticasone propionate and salmeterol utilizing data from 9 controlled clinical trials that included 350 subjects with asthma aged 4 to 77 years who received treatment with another fluticasone propionate and salmeterol MDPI product, the combination of HFA‑propelled fluticasone propionate and salmeterol inhalation aerosol, fluticasone propionate MDPI, HFA‑propelled fluticasone propionate inhalation aerosol, or CFC‑propelled fluticasone propionate inhalation aerosol. The population pharmacokinetic analyses for fluticasone propionate and salmeterol showed no clinically relevant effects of age, gender, race, body weight, body mass index, or percent of predicted FEV 1 on apparent clearance and apparent volume of distribution. Fluticasone Propionate/Salmeterol MDPI is not approved in pediatric patients younger than 12 years. Age: No pharmacokinetic studies have been performed with Fluticasone Propionate/Salmeterol MDPI in geriatric patients. Adolescents Aged 12 to 17 Years: A subgroup analysis was conducted to compare patients aged 12 to 17 (n=15) and ≥18 (n=23) years following administration of 232 mcg/14 mcg Fluticasone Propionate/Salmeterol MDPI. No overall differences in fluticasone propionate and salmeterol pharmacokinetics were observed. Male and Female Patients: A subgroup analysis was conducted to compare male (n=21) and female (n=16) adolescent and adult patients following administration of 232 mcg/14 mcg Fluticasone Propionate/Salmeterol MDPI. No overall differences in fluticasone propionate and salmeterol pharmacokinetics were observed. Patients with Renal Impairment : The effect of renal impairment of the pharmacokinetics of Fluticasone Propionate/Salmeterol MDPI has not been evaluated. Patients with Hepatic Impairment : Formal pharmacokinetic studies using Fluticasone Propionate/Salmeterol MDPI have not been conducted in patients with hepatic impairment. However, since both fluticasone propionate and salmeterol are predominantly cleared by hepatic metabolism, impairment of liver function may lead to accumulation of fluticasone propionate and salmeterol in plasma [see Use in Specific Populations ( 8.6 )] . Drug Interaction Studies In a single-dose trial, the presence of salmeterol did not alter fluticasone propionate exposure. No studies have been performed with Fluticasone Propionate/Salmeterol MDPI to investigate the effect of fluticasone propionate on salmeterol pharmacokinetics when given in combination. Drug Interaction Studies with Another Fluticasone Propionate/Salmeterol MDPI Product : The population pharmacokinetic analysis from 9 controlled clinical trials in 350 subjects with asthma showed no significant effects on fluticasone propionate or salmeterol pharmacokinetics following co-administration with beta 2 -agonists, corticosteroids, antihistamines, or theophyllines. Strong CYP3A4 Inhibitors: Fluticasone propionate is a substrate of CYP3A4. Coadministration of fluticasone propionate and ritonavir, a strong CYP3A4 inhibitor, is not recommended based upon a multiple-dose, crossover drug interaction trial in 18 healthy subjects [see Drug Interactions ( 7.1 )] . Plasma fluticasone propionate concentrations following fluticasone propionate aqueous nasal spray alone were undetectable (<10 pg/mL) in most subjects, and when concentrations were detectable, peak levels (C max ) averaged 11.9 pg/mL (range: 10.8 to 14.1 pg/mL) and AUC 0-τ averaged 8.43 pg•h/mL (range: 4.2 to 18.8 pg•h/mL). However, the fluticasone propionate C max and AUC 0-τ increased to 318 pg/mL (range: 110 to 648 pg/mL) and 3,102.6 pg•h/mL (range: 1,207.1 to 5,662.0 pg•h/mL), respectively, after 7 days of coadministration of ritonavir (100 mg twice daily) with fluticasone propionate aqueous nasal spray (200 mcg once daily). This significant increase in plasma fluticasone propionate exposure resulted in a significant decrease (86%) in serum cortisol AUC. Ketoconazole: In a placebo-controlled crossover trial in 8 healthy adult volunteers, coadministration of a single dose of orally inhaled fluticasone propionate (1,000 mcg) with multiple doses of ketoconazole (200 mg) to steady state resulted in increased plasma fluticasone propionate exposure, a reduction in plasma cortisol AUC, and no effect on urinary excretion of cortisol. In a placebo-controlled, crossover drug interaction trial in 20 healthy male and female subjects, coadministration of salmeterol (50 mcg twice daily) and ketoconazole, a strong CYP3A4 inhibitor, (400 mg once daily) for 7 days resulted in a significant increase in plasma salmeterol exposure as determined by a 16-fold increase in AUC (ratio with and without ketoconazole 15.76 [90% CI: 10.66, 23.31]) mainly due to increased bioavailability of the swallowed portion of the dose. Peak plasma salmeterol concentrations were increased by 1.4-fold (90% CI: 1.23, 1.68). Three (3) out of 20 subjects (15%) were withdrawn from salmeterol and ketoconazole coadministration due to beta-agonist-mediated systemic effects (2 with QTc prolongation and 1 with palpitations and sinus tachycardia). Coadministration of salmeterol and ketoconazole did not result in a clinically significant effect on mean heart rate, mean blood potassium, or mean blood glucose. Although there was no statistical effect on the mean QTc, coadministration of salmeterol and ketoconazole was associated with more frequent increases in QTc duration compared with salmeterol administration alone and placebo administration. Erythromycin: In a multiple-dose drug interaction trial, coadministration of orally inhaled fluticasone propionate (500 mcg twice daily) and erythromycin (333 mg 3 times daily) did not affect fluticasone propionate pharmacokinetics. In a repeat-dose trial in 13 healthy subjects, concomitant administration of erythromycin (a moderate CYP3A4 inhibitor) and salmeterol inhalation aerosol resulted in a 40% increase in salmeterol C max at steady state (ratio with and without erythromycin 1.4 [90% CI: 0.96, 2.03], P = 0.12), a 3.6-beat/min increase in heart rate ([95% CI: 0.19, 7.03], P<0.04), a 5.8-msec increase in QTc interval ([95% CI: -6.14, 17.77], P = 0.34), and no change in plasma potassium.

Animal Pharmacology And Or Toxicology

13.2 Animal Toxicology and/or Pharmacology Studies in laboratory animals (minipigs, rodents, and dogs) have demonstrated the occurrence of cardiac arrhythmias and sudden death (with histologic evidence of myocardial necrosis) when beta‑agonists and methylxanthines are administered concurrently. The clinical relevance of these findings is unknown.

Carcinogenesis And Mutagenesis And Impairment Of Fertility

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Fluticasone propionate : Fluticasone propionate demonstrated no tumorigenic potential in mice at oral doses up to 1000 mcg/kg (approximately 10 times the MRHDID for adults on a mcg/m 2 basis) for 78 weeks or in rats at inhalation doses up to 57 mcg/kg (approximately equivalent to the MRHDID for adults on a mcg/m 2 basis) for 104 weeks. Fluticasone propionate did not induce gene mutation in prokaryotic or eukaryotic cells in vitro. No significant clastogenic effect was seen in cultured human peripheral lymphocytes in vitro or in the in vivo mouse micronucleus test. Fertility and reproductive performance were unaffected in male and female rats at subcutaneous doses up to 50 mcg/kg (approximately equivalent to the MRHDID for adults on a mcg/m 2 basis). Salmeterol : In an 18‑month carcinogenicity study in CD‑mice, salmeterol at oral doses of 1400 mcg/kg and above (approximately 240 times the MRHDID on a mcg/m 2 basis) caused a dose‑related increase in the incidence of smooth muscle hyperplasia, cystic glandular hyperplasia, leiomyomas of the uterus, and ovarian cysts. No tumors were seen at 200 mcg/kg (approximately 35 times the MRHDID on a mcg/m 2 basis). In a 24 month oral and inhalation carcinogenicity study in Sprague Dawley rats, salmeterol caused a dose related increase in the incidence of mesovarian leiomyomas and ovarian cysts at doses of 680 mcg/kg and above (approximately 240 times the MRHDID on a mcg/m 2 basis). No tumors were seen at 210 mcg/kg (approximately 75 times the MRHDID on a mcg/m 2 basis). These findings in rodents are similar to those reported previously for other beta adrenergic agonist drugs. The relevance of these findings to human use is unknown. Salmeterol produced no detectable or reproducible increases in microbial and mammalian gene mutation in vitro. No clastogenic activity occurred in vitro in human lymphocytes or in vivo in a rat micronucleus test. Fertility and reproductive performance were unaffected in male and female rats at oral doses up to 2000 mcg/kg (approximately 690 times the MRHDID for adults on a mcg/m 2 basis).

The relevance of these findings to human use is unknown. Salmeterol produced no detectable or reproducible increases in microbial and mammalian gene mutation in vitro. No clastogenic activity occurred in vitro in human lymphocytes or in vivo in a rat micronucleus test. Fertility and reproductive performance were unaffected in male and female rats at oral doses up to 2000 mcg/kg (approximately 690 times the MRHDID for adults on a mcg/m 2 basis). 13.2 Animal Toxicology and/or Pharmacology Studies in laboratory animals (minipigs, rodents, and dogs) have demonstrated the occurrence of cardiac arrhythmias and sudden death (with histologic evidence of myocardial necrosis) when beta‑agonists and methylxanthines are administered concurrently. The clinical relevance of these findings is unknown.

Information For Patients

17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling (Patient Information and Instructions for Use). Patients should be given the following information: Serious Asthma Events Inform patients with asthma that LABA when used alone increases the risk of asthma-related hospitalization and asthma-related death. Available data show that when ICS and LABA are used together, such as with Fluticasone Propionate/Salmeterol MDPI, there is not a significant increase in the risk of these events [see Warnings and Precautions ( 5.1 )] . Not for Acute Symptoms Inform patients that Fluticasone Propionate/Salmeterol MDPI is not meant to relieve acute asthma symptoms and extra doses should not be used for that purpose. Advise patients to treat acute asthma symptoms with an inhaled, short‑acting beta 2 ‑agonist such as albuterol. Provide patients with such medication and instruct them in how it should be used [see Warnings and Precautions ( 5.2 )] . Instruct patients to seek medical attention if they experience any of the following: 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 Tell patients they should not stop therapy with Fluticasone Propionate/Salmeterol without physician/provider guidance since symptoms may recur after discontinuation. Avoid Use Additional Long-Acting Beta 2 ‑Agonists Instruct patients not to use other LABA for asthma [see Warnings and Precautions ( 5.3 )] . Oropharyngeal Candidiasis Inform patients that localized infections with Candida albicans occurred in the mouth and pharynx in some patients. If oropharyngeal candidiasis develops, treat it with appropriate local or systemic (i.e., oral) antifungal therapy while still continuing therapy with Fluticasone Propionate/Salmeterol MDPI, but at times therapy with Fluticasone Propionate/Salmeterol MDPI may need to be temporarily interrupted under close medical supervision. Rinsing the mouth with water without swallowing after inhalation is advised to help reduce the risk of thrush [see Warnings and Precautions ( 5.4 )] . Immunosuppression and Infections Warn patients who are on immunosuppressant doses of corticosteroids to avoid exposure to chickenpox or measles and, if exposed, to consult their physicians without delay. Inform patients of potential worsening of existing tuberculosis, fungal, bacterial, viral, or parasitic infections; or ocular herpes simplex [see Warnings and Precautions ( 5.5 )] . Hypercorticism and Adrenal Suppression Advise patients that Fluticasone Propionate/Salmeterol MDPI may cause systemic corticosteroid effects of hypercorticism and adrenal suppression. Additionally, inform patients that deaths due to adrenal insufficiency have occurred during and after transfer from systemic corticosteroids. Patients should taper slowly from systemic corticosteroids if transferring to Fluticasone Propionate/Salmeterol MDPI [see Warnings and Precautions ( 5.7 )] . Immediate Hypersensitivity Reactions Advise patients that immediate hypersensitivity reactions (e.g., urticaria, angioedema, rash, bronchospasm, hypotension), including anaphylaxis, may occur after administration of Fluticasone Propionate/Salmeterol MDPI. Patients should discontinue Fluticasone Propionate/Salmeterol MDPI if such reactions occur and contact their healthcare provider or get emergency medical help. There have been reports of anaphylactic reactions in patients with severe milk protein allergy after inhalation of powder products containing lactose; therefore, patients with severe milk protein allergy should not take Fluticasone Propionate/Salmeterol MDPI [see Warnings and Precautions ( 5.10 )] . Reduction in Bone Mineral Density Advise patients who are at an increased risk for decreased BMD that the use of corticosteroids may pose an additional risk [see Warnings and Precautions ( 5.12 )] . Reduced Growth Velocity Inform patients that orally inhaled corticosteroids, including fluticasone propionate, may cause a reduction in growth velocity when administered to adolescent patients. Physicians should closely follow the growth of adolescents taking corticosteroids by any route [see Warnings and Precautions ( 5.13 )] . Ocular Effects Long-term use of inhaled corticosteroids may increase the risk of some eye problems (cataracts or glaucoma); consider regular eye examinations [see Warnings and Precautions ( 5.14 )] . Risks Associated with Beta‑Agonist Therapy Inform patients of adverse effects associated with beta 2 ‑agonists, such as palpitations, chest pain, rapid heart rate, tremor, or nervousness [see Warnings and Precautions ( 5.11 )] . Pregnancy Inform patients who are pregnant or nursing that they should contact their physician about the use of Fluticasone Propionate/Salmeterol MDPI [see Use in Specific Populations ( 8.1 )] . Use Daily for Best Effect Patients should use Fluticasone Propionate/Salmeterol MDPI at regular intervals as directed. The daily dosage of Fluticasone Propionate/Salmeterol MDPI should not exceed 1 inhalation twice a day. Advise patients, if they miss a dose, to take their next dose at the same time they normally do and to not take 2 doses at one time. Individual patients will experience a variable time to onset and degree of symptom relief and full benefit may not be achieved until treatment has been administered for 1 to 2 weeks or longer. Patients should not increase the prescribed dosage but should contact their physicians if symptoms do not improve or if the condition worsens. Instruct patients not to stop use of Fluticasone Propionate/Salmeterol MDPI abruptly. Patients should contact their physicians immediately if they discontinue use of Fluticasone Propionate/Salmeterol MDPI. Dose Counter Instruct patients that Fluticasone Propionate/Salmeterol MDPI has a dose counter that displays the number of actuations (inhalations) left in the inhaler. When the patient receives a new inhaler, the number 60 will be displayed. The dose counter will count down each time the mouthpiece is opened and closed. When the dose counter reaches 20, the color of the numbers will change to red to remind the patient to contact their pharmacist or healthcare provider for a refill of their medication. When the dose counter reaches 0, the patient should stop using the inhaler, and dispose of it in accordance with state and local regulations. Caring for and Storing the Inhaler Instruct patients to not open their inhaler unless they are taking a dose. Repeated opening and closing the cover without taking medication will waste medication and may damage the inhaler. Advise patients to keep their inhaler dry and clean at all times. Never wash or put any part of the inhaler in water. Patient should replace inhaler if washed or placed in water. Advise patients to immediately replace inhaler if mouthpiece cover is damaged or broken. Gently wipe the mouthpiece with a dry cloth or tissue as needed. Instruct patients to store the inhaler at room temperature and to avoid exposure to extreme heat, cold, or humidity. Instruct patients to never take the inhaler apart. Inform patients to discard this product when the dose counter displays 0, 30 days after opening the foil pouch or after the expiration date on the product, whichever comes first.

PATIENT INFORMATION

Fluticasone Propionate and Salmeterol inhalation powder 55 mcg/14 mcg Fluticasone Propionate and Salmeterol inhalation powder 113 mcg/14 mcg Fluticasone Propionate and Salmeterol inhalation powder 232 mcg/14 mcg

for oral inhalation use

What is fluticasone propionate/salmeterol inhalation powder?

Fluticasone Propionate/salmeterol inhalation powder combines the inhaled corticosteroid (ICS) medicine fluticasone propionate and the LABA medicine salmeterol.

ICS medicines such as fluticasone propionate help to decrease inflammation in the lungs. Inflammation in the lungs can lead to breathing problems.

● LABA medicines such as salmeterol help the muscles around the airways in your lungs stay relaxed to prevent symptoms, such as wheezing, cough, chest tightness, and shortness of breath. These symptoms can happen when the muscles around the airways tighten. This makes it hard to breathe.

● Fluticasone Propionate/Salmeterol inhalation powder is a prescription medicine used to control symptoms of asthma and to prevent symptoms such as wheezing in people 12 years of age and older.

This product contains salmeterol. LABA medicines such as salmeterol when used alone increase the risk of hospitalizations and death from asthma problems. Fluticasone Propionate/Salmeterol inhalation powder contains an ICS and a LABA. When an ICS and LABA are used together, there is not a significant increased risk in hospitalizations and death from asthma problems.

Fluticasone Propionate/Salmeterol inhalation powder is not for people 12 years of age and older with asthma who are well controlled with an asthma control medicine, such as a low or medium dose of an inhaled corticosteroid medicine. Fluticasone Propionate/Salmeterol inhalation powder is for people 12 years of age and older with asthma who need both an ICS and LABA medicine.

Fluticasone Propionate/Salmeterol inhalation powder is not used to relieve sudden breathing problems and will not replace a rescue inhaler.

It is not known if Fluticasone Propionate/Salmeterol inhalation powder is safe and effective in children younger than 12 years of age.

Do not use Fluticasone Propionate/Salmeterol inhalation powder:

to treat sudden, severe symptoms of asthma.

● if you have a severe allergy to milk proteins. Ask your healthcare provider if you are not sure.

● if you are allergic to fluticasone propionate or any of the inactive ingredients in Fluticasone Propionate/Salmeterol inhalation powder. See the end of this leaflet for a complete list of ingredients in this product.

Tell your healthcare provider about all of your medical conditions, including if you:

● have heart problems.

● have high blood pressure.

● have seizures.

● have thyroid problems.

● have diabetes.

● have liver problems.

● have weak bones (osteoporosis).

● have an immune system problem.

● have eye problems, such as glaucoma or cataracts.

● are allergic to milk proteins.

● have any type of viral, bacterial, fungal, or parasitic infection.

● are exposed to chickenpox or measles.

● are pregnant or plan to become pregnant. It is not known if Fluticasone Propionate/Salmeterol inhalation powder may harm your unborn baby.

● are breastfeeding. It is not known if the medicines in Fluticasone Propionate/Salmeterol inhalation powder pass into your breast milk and if they can harm your baby.

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Fluticasone Propionate/Salmeterol inhalation powder and certain other medicines may interact with each other. This may cause serious side effects. Especially, tell your healthcare provider if you take antifungal or anti-HIV medicines.

    weakened immune system and increased chance of getting infections (immunosuppression).

    reduced adrenal function (adrenal insufficiency). Adrenal insufficiency is a condition where the adrenal glands do not make enough steroid hormones. This can happen when you stop taking oral corticosteroid medicines (such as prednisone) and start taking a medicine containing an inhaled steroid (such as Fluticasone Propionate/Salmeterol inhalation powder). When your body is under stress such as from fever, trauma (such as a car accident), infection, or surgery, adrenal insufficiency can get worse and may cause death.

    Symptoms of adrenal insufficiency include:

    ○ feeling tired ○ nausea and vomiting

    ○ lack of energy ○ low blood pressure

    ○ weakness

    sudden breathing problems immediately after inhaling your medicine. If you have sudden breathing problems immediately after inhaling your medicine, stop using Fluticasone Propionate/Salmeterol inhalation powder and call your healthcare provider right away.

    serious allergic reactions. Stop using Fluticasone Propionate/Salmeterol inhalation powder and call your healthcare provider or get emergency medical help if you get any of the following symptoms of a serious allergic reaction:

    Clinical Studies

    14 CLINICAL STUDIES The safety and efficacy of Fluticasone Propionate/Salmeterol Multidose Dry Powder Inhaler (FS MDPI) were evaluated in 3004 patients with asthma. The development program included 2 confirmatory trials of 12 weeks duration, a 26 week safety trial and three dose-ranging trials. The efficacy of Fluticasone Propionate/Salmeterol MDPI is based primarily on the dose-ranging trials and the confirmatory trials described below. 14.1 Dose-Ranging Studies in Patients with Asthma Six doses of fluticasone propionate ranging from 16 mcg to 434 mcg (expressed as metered doses) administered twice daily via MDPI were evaluated in 2 randomized, double-blind, placebo-controlled 12 week trials in patients with asthma. Trial 201 was conducted in patients whose asthma was uncontrolled at baseline and had been treated by short-acting beta 2 -agonist alone or in combination with non-corticosteroid asthma medication. Low dose inhaled corticosteroids (ICS)-treated patients may have been included after a minimum of 2 weeks washout. This trial contained an open-label active comparator fluticasone propionate inhalation powder 100 mcg administered twice daily. Trial 202 was conducted in patients whose asthma was uncontrolled at baseline and had been treated with high dose ICS with or without a LABA. This study contained an open-label active comparator fluticasone propionate inhalation powder 250 mcg twice daily. The trials were dose-ranging trials of fluticasone propionate MDPI not designed to provide comparative effectiveness data and should not be interpreted as evidence of superiority/inferiority to fluticasone propionate inhalation powder. The metered doses for fluticasone MDPI (16, 28, 59, 118, 225, 434 mcg) used in Trial 201 and Trial 202 (see Figure 1) are slightly different from the metered doses for the comparator products (fluticasone inhalation powder) and the Phase 3 investigational products which are the basis of the proposed commercial labeled claim (55, 113, 232 mcg for fluticasone). The changes in doses between Phase 2 and 3 resulted from optimization of the manufacturing process. Figure 1: Baseline Adjusted Least Square Mean Change in Trough Morning FEV 1 (L) over 12 weeks (FAS) a FAS = full analysis set; a Trials were not designed to provide comparative effectiveness data and should not be interpreted as superiority/inferiority to fluticasone propionate inhalation powder The efficacy and safety of four doses of salmeterol xinafoate were evaluated in a double blind, 6-period crossover study compared with single dose fluticasone propionate MDPI and open label fluticasone propionate/salmeterol 100 mcg/50 mcg dry powder inhaler (DPI) as comparator in patients with persistent asthma. The trials were dose-ranging trials of the salmeterol component of Fluticasone Propionate/Salmeterol MDPI and not designed to provide comparative effectiveness data and should not be interpreted as evidence of superiority/inferiority to fluticasone propionate/salmeterol inhalation powder. The salmeterol doses studied were 6.8 mcg, 13.2 mcg, 26.8 mcg and 57.4 mcg in combination with fluticasone propionate 118 mcg delivered by MDPI (expressed as metered dose). The metered doses for salmeterol (6.8, 13.2, 26.8, 57.4 mcg) used in this study are slightly different from the metered doses for the comparator products (fluticasone/salmeterol inhalation powder) and the Phase 3 investigational products which are the basis of the proposed commercial labeled claim (55, 113, 232 mcg for fluticasone and 14 mcg for salmeterol). The phase 3 and commercial products were optimized to better match the strengths to the comparators. Plasma for pharmacokinetic characterization was obtained at each dosing period. Fluticasone propionate/salmeterol xinafoate MDPI 118 mcg/13.2 mcg had similar clinical efficacy with lower systemic exposure when compared to the 50 mcg of salmeterol in fluticasone propionate/salmeterol 100 mcg/50 mcg dry powder inhaler (Figure 2). Figure 2: Mean Baseline Adjusted FEV 1 (mL) over 12 Hours (FAS) a FS MDPI = fluticasone propionate/salmeterol multidose dry powder inhaler; Fp MDPI = fluticasone propionate multidose dry powder inhaler; FS DPI = fluticasone propionate/salmeterol dry powder inhaler; FAS = full analysis set; FEV 1 = forced expiratory volume in 1 second; a Trial was not designed to provide comparative effectiveness data and should not be interpreted as superiority/inferiority to fluticasone propionate/salmeterol inhalation powder. Figure 1 Figure 2 14.2 Trials in the Treatment of Asthma Adult and Adolescent Patients Aged 12 Years and Older : Two 12-week randomized, double-blind, placebo-controlled, parallel-group, global clinical trials (Trials 1 and 2) were conducted in 1375 adult and adolescent patients (aged 12 years and older, with baseline FEV 1 40% to 85% of predicted normal) with asthma that was not optimally controlled on their current therapy. Patients were randomized to receive 1 inhalation twice a day of Fluticasone Propionate/Salmeterol MDPI, fluticasone propionate MDPI alone, or placebo. Maintenance asthma therapies were discontinued at randomization. Trial 1 : In this trial, adolescents and adult patients with persistent symptomatic asthma despite low-dose or mid-dose inhaled corticosteroid (ICS) or ICS/LABA therapy were included. After completing a run-in period where patients were treated with beclomethasone dipropionate inhalation aerosol 40 mcg twice daily and a single blind placebo MDPI, the patients who met the randomization criteria were randomized to 1 inhalation twice a day of the following treatments: Placebo MDPI (n=130) Fluticasone propionate MDPI 55 mcg (n=129) Fluticasone propionate MDPI 113 mcg (n=130) Fluticasone Propionate/Salmeterol MDPI 55 mcg/14 mcg (n=129), or Fluticasone Propionate/Salmeterol MDPI 113 mcg/14 mcg (n=129) Baseline FEV 1 measurements were similar across treatments: fluticasone propionate MDPI 55 mcg 2.132 L, fluticasone propionate MDPI 113 mcg 2.166 L, Fluticasone Propionate/Salmeterol MDPI 55 mcg/14 mcg 2.302 L, Fluticasone Propionate/Salmeterol MDPI 113 mcg/14 mcg 2.162 L, and placebo 2.188 L. The primary endpoints for this trial were the change from baseline in trough FEV 1 at week 12 for all patients and standardized baseline-adjusted FEV 1 AUEC 0-12h at week 12 analyzed for a subset of 312 patients who performed postdose serial spirometry. Patients in both Fluticasone Propionate/Salmeterol MDPI treatment groups had significantly greater improvements in trough FEV 1 compared with both Fluticasone Propionate MDPI treatment groups and the placebo group. Fluticasone Propionate/Salmeterol MDPI 113 mcg/14 mcg: LS mean change of 0.315 L at 12 weeks Fluticasone Propionate/Salmeterol MDPI 55 mcg/14 mcg: LS mean change of 0.319 L at 12 weeks Fluticasone propionate MDPI 113 mcg: LS mean change of 0.204 L at 12 weeks Fluticasone propionate MDPI 55 mcg: LS mean change of 0.172 L at 12 weeks Placebo: LS mean change of 0.053 L at 12 weeks The estimated mean differences between: Fluticasone Propionate/Salmeterol MDPI 55 mcg/14 mcg and Fluticasone Propionate/Salmeterol MDPI 113 mcg/14 mcg compared to placebo were 0.266 L (95% CI: 0.172, 0.360) and 0.262 L (95% CI: 0.168, 0.356), respectively. Fluticasone propionate MDPI 55 mcg and fluticasone propionate MDPI 113 mcg compared to placebo were 0.119 L (95% CI: 0.025, 0.212) and 0.151 L (95% CI: 0.057, 0.244), respectively. Fluticasone Propionate/Salmeterol MDPI 113 mcg/14 mcg and Fluticasone Propionate MDPI 113 mcg was 0.111 L (95% CI: 0.017, 0.206). Fluticasone Propionate/Salmeterol MDPI 55 mcg/14 mcg and Fluticasone Propionate MDPI 55 mcg was 0.147 L (95% CI: 0.053, 0.242). In addition, the mean FEV 1 results at each visit are displayed in Figure 3. Figure 3: Mean Change from Baseline in Trough FEV 1 at Each Visit by Treatment Group Trial 1 (FAS) FAS = full analysis set; FEV 1 = forced expiratory volume in 1 second; Placebo = placebo MDPI Supportive evidence of efficacy for Fluticasone Propionate/Salmeterol MDPI compared with placebo was derived from secondary endpoints such as the weekly average of daily trough morning peak expiratory flow and total daily use of rescue medication. The Asthma Quality of Life Questionnaire (AQLQ) for patients age ≥ 18 years or the pediatric AQLQ (PAQLQ) for patients aged 12-17 were assessed in Trial 1. The responder rate for both measures was defined as an improvement in score of 0.5 or more as threshold. In Trial 1, the responder rate for patients receiving Fluticasone Propionate/Salmeterol MDPI 55 mcg/14 mcg and Fluticasone Propionate/Salmeterol MDPI 113 mcg/14 mcg was 51% and 57%, respectively, compared to 40% for patients receiving placebo, with an odds ratio of 1.53 (95% CI: 0.93, 2.55) and 2.04 (95% CI: 1.23, 3.41), respectively. Improvements in lung function occurred within 15 minutes of the first dose (15 minutes postdose). Compared to placebo the difference in LS mean change from baseline in FEV 1 for Fluticasone Propionate/Salmeterol MDPI 55 mcg/14 mcg and 113 mcg/14 mcg was 0.216 and 0.164 L, respectively (unadjusted p-value <0.0001 for both dosages compared with placebo). Refer to Figure 4 below. Maximum improvement in FEV 1 generally occurred within 3 hours for Fluticasone Propionate/Salmeterol MDPI 55 mcg/14 mcg and within 6 hours for Fluticasone Propionate/Salmeterol MDPI 113 mcg/14 mcg and improvements were sustained over the 12 hours of testing at weeks 1 and 12 (Figure 4 and Figure 5). Following the initial dose, predose FEV 1 relative to day 1 baseline improved markedly over the first week of treatment and the improvement was sustained over the 12 weeks of treatment in the trial. No diminution in the 12 hour bronchodilator effect was observed with either Fluticasone Propionate/Salmeterol MDPI dose as assessed by FEV 1 following 12 weeks of therapy.

After completing a run-in period where patients were treated with single-blind Fluticasone Propionate MDPI 55 mcg twice daily replacing their current asthma therapy, patients who met the randomization criteria were randomized to 1 inhalation twice a day of the following treatments: Placebo MDPI (n=145) Fluticasone propionate MDPI 113 mcg (n=146) Fluticasone propionate MDPI 232 mcg (n=146) Fluticasone Propionate/Salmeterol MDPI 113 mcg/14 mcg (n=145) Fluticasone Propionate/Salmeterol MDPI 232 mcg/14 mcg (n=146) Baseline FEV 1 measurements were similar across treatments: fluticasone propionate MDPI 113 mcg 2.069 L, fluticasone propionate MDPI 232 mcg 2.075 L, Fluticasone Propionate/Salmeterol MDPI 113 mcg/14 mcg 2.157 L, Fluticasone Propionate/Salmeterol MDPI 232 mcg/14 mcg 2.083 L and placebo 2.141 L. The primary endpoints for this trial were the change from baseline in trough FEV 1 at week 12 for all patients and standardized baseline-adjusted FEV 1 AUEC 0-12h at week 12 analyzed for a subset of 312 patients who performed postdose serial spirometry. Efficacy results in this trial were similar to those observed in Trial 1. Patients in both Fluticasone Propionate/Salmeterol MDPI groups had significantly greater improvements in trough FEV 1 compared with the fluticasone propionate MDPI groups and the placebo group: Fluticasone Propionate/Salmeterol MDPI 113 mcg/14 mcg: LS mean change of 0.271 L at 12 weeks Fluticasone Propionate/Salmeterol MDPI 232 mcg/14 mcg: LS mean change of 0.272 L at 12 weeks Fluticasone propionate MDPI 113 mcg: LS mean change of 0.119 L at 12 weeks Fluticasone propionate MDPI 232 mcg: LS mean change of 0.179 L at 12 weeks, and Placebo: LS mean change of -0.004 L at 12 weeks. Estimated mean differences between: Fluticasone Propionate/Salmeterol MDPI 113 mcg/14 mcg and Fluticasone Propionate/Salmeterol MDPI 232 mcg/14 mcg compared to placebo were 0.274 L (95% CI: 0.189, 0.360) and 0.276 L (95% CI: 0.191, 0.361), respectively. Fluticasone propionate MDPI 113 mcg and fluticasone propionate MDPI 232 mcg compared to placebo were 0.123 L (95% CI: 0.038, 0.208) and 0.183 L (95% CI: 0.098, 0.268), respectively. Fluticasone Propionate/Salmeterol MDPI 232 mcg/14 mcg and fluticasone propionate MDPI 232 mcg was 0.093 L (95% CI: 0.009, 0.178). Fluticasone Propionate/Salmeterol MDPI 113 mcg/14 mcg and fluticasone propionate MDPI 113 mcg was 0.152 L (95% CI: 0.066, 0.237). In addition, the mean FEV 1 results at each visit are displayed in Figure 6. Figure 6: Mean Change from Baseline in Trough FEV 1 at Each Visit by Treatment Group Trial 2 (FAS) FAS = full analysis set; FEV 1 = forced expiratory volume in 1 second; Placebo = placebo MDPI Supportive evidence of efficacy for Fluticasone Propionate/Salmeterol MDPI compared with placebo was derived from secondary endpoints such as the weekly average of daily trough morning peak expiratory flow and total daily use of rescue medication. There were fewer withdrawals due to worsening asthma in patients treated with Fluticasone Propionate/Salmeterol MDPI than with placebo. The AQLQ for patients age ≥ 18 years or the PAQLQ for patients aged 12-17 were assessed in Trial 2. The responder rate for both measures was defined as an improvement in score of 0.5 or more as threshold. In Trial 2, the responder rate for patients receiving Fluticasone Propionate/Salmeterol MDPI 113 mcg/14 mcg and Fluticasone Propionate/Salmeterol MDPI 232 mcg/14 mcg was 48% and 41%, respectively, compared to 27% for patients receiving placebo, with an odds ratio of 2.59 (95% CI: 1.56, 4.31) and 1.94 (95% CI: 1.16, 3.23), respectively. Improvements in lung function occurred within 15 minutes of the first dose (15 minutes postdose). Compared with placebo, for Fluticasone Propionate/Salmeterol MDPI 113 mcg/14 mcg and 232 mcg/14 mcg the difference in LS mean change from baseline in FEV 1 was 0.160 L and 0.187 L, respectively (unadjusted p-value <0.0001 for both doses compared with placebo). Maximum improvement in FEV 1 generally occurred within 3 hours for both Fluticasone Propionate/Salmeterol MDPI dose groups, and improvements were sustained over the 12 hours of testing at weeks 1 and 12 (Figure 7 and Figure 8). Following the initial dose, predose FEV 1 relative to day 1 baseline improved markedly over the first week of treatment and the improvement was sustained over the 12 weeks of treatment in the trial. No diminution in the 12 hour bronchodilator effect was observed with either Fluticasone Propionate/Salmeterol MDPI dose as assessed by FEV 1 following 12 weeks of therapy.

    Geriatric Use

    8.5 Geriatric Use No overall differences in safety or effectiveness were observed in data collected in 54 subjects aged 65 years and older versus younger subjects who were treated with Fluticasone Propionate/Salmeterol MDPI in placebo-controlled Phase 2 and 3 asthma studies.

    Pediatric Use

    8.4 Pediatric Use The safety and effectiveness of Fluticasone Propionate/Salmeterol MDPI have been established for the treatment of asthma in pediatric patients aged 12 years and older whose asthma (1) is inadequately controlled on a long term asthma control medication or (2) warrants initiation of treatment with both an ICS and a LABA. Use of Fluticasone Propionate/Salmeterol MDPI in pediatric patients aged 12 to 17 years for this indication is supported by evidence from two adequate and well-controlled trials in pediatric patients 12 years old and older with persistent symptomatic asthma despite ICS or ICS/LABA therapy (Trials 1 and 2) [see Clinical Studies ( 14 )]. In these trials, 58 adolescents received Fluticasone Propionate/Salmeterol MDPI one inhalation twice daily. The safety and effectiveness of Fluticasone Propionate/Salmeterol MDPI have not been established in pediatric patients younger than 12 years of age for the treatment of asthma. Effectiveness was not demonstrated in one adequate and well-controlled study conducted in 211 patients aged 4 to 11 years with persistent asthma on a stable asthma regimen who were treated with Fluticasone Propionate/Salmeterol MDPI 55 mcg/14 mcg one inhalation twice daily. Effect on Growth Inhaled corticosteroids, including fluticasone propionate, a component of this product, may cause a reduction in growth velocity in adolescents [see Warning and Precautions ( 5.13 )] . The growth of pediatric patients receiving ICS, including Fluticasone Propionate/Salmeterol MDPI, should be monitored. If an adolescent on any corticosteroid appears to have growth suppression, the possibility that he/she is particularly sensitive to this effect of corticosteroids should be considered. In such patients, the potential growth effects of prolonged ICS treatment should be weighed against the clinical benefits obtained. To minimize the systemic effects of ICS, including Fluticasone Propionate/Salmeterol MDPI, each patient should be titrated to the lowest strength that effectively controls his/her asthma [see Dosage and Administration ( 2 )].

    Pregnancy

    8.1 Pregnancy Risk Summary There are no randomized clinical studies of fluticasone propionate/salmeterol MDPI or individual monoproducts, fluticasone propionate and salmeterol, in pregnant women. There are clinical considerations with the use of Fluticasone Propionate/Salmeterol MDPI in pregnant women [see Clinical Considerations] . Animal reproduction studies are available with the combination of fluticasone propionate and salmeterol as well as individual components. In animals, teratogenicity characteristic of corticosteroids, decreased fetal body weight and/or skeletal variations, in rats, mice, and rabbits were observed with subcutaneously administered maternal toxic doses of fluticasone propionate less than the maximum recommended human daily inhaled dose (MRHDID) on a mcg/m 2 basis [see Data] . However, fluticasone propionate administered via inhalation to rats decreased fetal body weight, but did not induce teratogenicity at a maternal toxic dose less than the MRHDID on a mcg/m 2 basis [see Data] . Experience with oral corticosteroids suggests that rodents are more prone to teratogenic effects from corticosteroids than humans. Oral administration of salmeterol to pregnant rabbits caused teratogenicity characteristic of beta-adrenoceptor stimulation at maternal doses approximately 700 times the MRHDID on a mcg/m 2 basis. These adverse effects generally occurred at large multiples of the MRHDID when salmeterol was administered by the oral route to achieve high systemic exposures. No such effects occurred at an oral salmeterol dose approximately 420 times the MRHDID [see Data] . The estimated risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 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. Data Animal Data Fluticasone Propionate and Salmeterol: In an embryo/fetal development study with pregnant rats that received the combination of subcutaneous administration of fluticasone propionate and oral administration of salmeterol at doses of 0/1000, 30/0, 10/100, 30/1000, and 100/10,000 mcg/kg/day (as fluticasone propionate/salmeterol) during the period of organogenesis, findings were generally consistent with the individual monoproducts and there was no exacerbation of expected fetal effects. Omphalocele, increased embryo/fetal deaths, decreased body weight, and skeletal variations were observed in rat fetuses, in the presence of maternal toxicity, when combining fluticasone propionate at a dose approximately 2 times the MRHDID (on a mcg/m 2 basis at a maternal subcutaneous dose of 100 mcg/kg/day) and a dose of salmeterol at approximately 3500 times the MRHDID (on a mcg/m 2 basis at a maternal oral dose of 10,000 mcg/kg/day). The rat no observed adverse effect level (NOAEL) was observed when combining fluticasone propionate at a dose 0.6 times the MRHDID (on a mcg/m 2 basis at a maternal subcutaneous dose of 30 mcg/kg/day) and a dose of salmeterol at approximately 350 times the MRHDID (on a mcg/m 2 basis at a maternal oral dose of 1000 mcg/kg/day). In an embryo/fetal development study with pregnant mice that received the combination of subcutaneous administration of fluticasone propionate and oral administration of salmeterol at doses of 0/1400, 40/0, 10/200, 40/1400, or 150/10,000 mcg/kg/day (as fluticasone propionate/salmeterol) during the period of organogenesis, findings were generally consistent with the individual monoproducts and there was no exacerbation of expected fetal effects. Cleft palate, fetal death, increased implantation loss, and delayed ossification were observed in mouse fetuses when combining fluticasone propionate at a dose approximately 1.4 times the MRHDID (on a mcg/m 2 basis at a maternal subcutaneous dose of 150 mcg/kg/day) and salmeterol at a dose approximately 1470 times the MRHDID (on a mcg/m 2 basis at a maternal oral dose of 10,000 mcg/kg/day). No developmental toxicity was observed at combination doses of fluticasone propionate up to approximately 0.8 times the MRHDID (on a mcg/m 2 basis at a maternal subcutaneous dose of 40 mcg/kg) and doses of salmeterol up to approximately 420 times the MRHDID (on a mcg/m 2 basis at a maternal oral dose of 1400 mcg/kg). Fluticasone Propionate: In embryo/fetal development studies with pregnant rats and mice dosed by the subcutaneous route throughout the period of organogenesis, fluticasone propionate was teratogenic in both species. Omphalocele, decreased body weight, and skeletal variations were observed in rat fetuses, in the presence of maternal toxicity, at a dose approximately 2 times the MRHDID (on a mcg/m 2 basis with a maternal subcutaneous dose of 100 mcg/kg/day). The rat NOAEL was observed at approximately 0.6 times the MRHDID (on a mcg/m 2 basis with a maternal subcutaneous dose of 30 mcg/kg/day). Cleft palate and fetal skeletal variations were observed in mouse fetuses at a dose approximately 0.5 times the MRHDID (on a mcg/m 2 basis with a maternal subcutaneous dose of 45 mcg/kg/day). The mouse NOAEL was observed with a dose approximately 0.16 times the MRHDID (on a mcg/m 2 basis with a maternal subcutaneous dose of 15 mcg/kg/day). In an embryo/fetal development study with pregnant rats dosed by the inhalation route throughout the period of organogenesis, fluticasone propionate produced decreased fetal body weights and skeletal variations, in the presence of maternal toxicity, at a dose approximately 0.5 times the MRHDID (on a mcg/m 2 basis with a maternal inhalation dose of 25.7 mcg/kg/day); however, there was no evidence of teratogenicity. The NOAEL was observed with a dose approximately 0.1 times the MRHDID (on a mcg/m 2 basis with a maternal inhalation dose of 5.5 mcg/kg/day). In an embryo/fetal development study in pregnant rabbits that were dosed by the subcutaneous route throughout organogenesis, fluticasone propionate produced reductions of fetal body weights, in the presence of maternal toxicity at doses approximately 0.02 times the MRHDID and higher (on a mcg/m 2 basis with a maternal subcutaneous dose of 0.57 mcg/kg/day). Teratogenicity was evident based upon a finding of cleft palate for 1 fetus at a dose approximately 0.2 times the MRHDID (on a mcg/m 2 basis with a maternal subcutaneous dose of 4 mcg/kg/day). The NOAEL was observed in rabbit fetuses with a dose approximately 0.004 times the MRHDID (on a mcg/m 2 basis with a maternal subcutaneous dose of 0.08 mcg/kg/day). In a pre- and post-natal development study in pregnant rats dosed by the subcutaneous route from late gestation through delivery and lactation (Gestation Day 17 to Postpartum Day 22), fluticasone propionate was not associated with decreases in pup body weight, and had no effects on developmental landmarks, learning, memory, reflexes, or fertility at doses up to approximate equivalence to the MRHDID (on a mcg/m 2 basis with maternal subcutaneous doses up to 50 mcg/kg/day). Fluticasone propionate crossed the placenta following subcutaneous administration to mice and rats and oral administration to rabbits. Salmeterol: In three embryo/fetal development studies, pregnant rabbits received oral administration of salmeterol at doses ranging from 100 to 10,000 mcg/kg/day during the period of organogenesis. In pregnant Dutch rabbits administered salmeterol doses approximately 700 times the MRHDID (on a mcg/m 2 basis at maternal oral doses of 1000 mcg/kg/day and higher), fetal toxic effects were observed characteristically resulting from beta‑adrenoceptor stimulation. These included precocious eyelid openings, cleft palate, sternebral fusion, limb and paw flexures, and delayed ossification of the frontal cranial bones. No such effects occurred at a salmeterol dose approximately 420 times the MRHDID (on a mcg/m 2 basis at a maternal oral dose of 600 mcg/kg/day). New Zealand White rabbits were less sensitive since only delayed ossification of the frontal cranial bones was seen at a salmeterol dose approximately 7,000 times the MRHDID (on a mcg/m 2 basis at a maternal oral dose of 10,000 mcg/kg/day). In two embryo/fetal development studies, pregnant rats received salmeterol by oral administration at doses ranging from 100 to 10,000 mcg/kg/day during the period of organogenesis. Salmeterol produced no maternal toxicity or embryo/fetal effects at doses up to 3500 times the MRHDID (on a mcg/m 2 basis at maternal oral doses up to 10,000 mcg/kg/day). In a peri-and post-natal development study in pregnant rats dosed by the oral route from late gestation through delivery and lactation, salmeterol at a dose 3500 times the MRHDID (on mcg/m 2 basis with a maternal oral dose of 10,000 mcg/kg/day) was fetotoxic and decreased the fertility of survivors. Salmeterol xinafoate crossed the placenta following oral administration to mice and rats.

In the U.S. general population, the estimated risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 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. Data Animal Data Fluticasone Propionate and Salmeterol: In an embryo/fetal development study with pregnant rats that received the combination of subcutaneous administration of fluticasone propionate and oral administration of salmeterol at doses of 0/1000, 30/0, 10/100, 30/1000, and 100/10,000 mcg/kg/day (as fluticasone propionate/salmeterol) during the period of organogenesis, findings were generally consistent with the individual monoproducts and there was no exacerbation of expected fetal effects. Omphalocele, increased embryo/fetal deaths, decreased body weight, and skeletal variations were observed in rat fetuses, in the presence of maternal toxicity, when combining fluticasone propionate at a dose approximately 2 times the MRHDID (on a mcg/m 2 basis at a maternal subcutaneous dose of 100 mcg/kg/day) and a dose of salmeterol at approximately 3500 times the MRHDID (on a mcg/m 2 basis at a maternal oral dose of 10,000 mcg/kg/day). The rat no observed adverse effect level (NOAEL) was observed when combining fluticasone propionate at a dose 0.6 times the MRHDID (on a mcg/m 2 basis at a maternal subcutaneous dose of 30 mcg/kg/day) and a dose of salmeterol at approximately 350 times the MRHDID (on a mcg/m 2 basis at a maternal oral dose of 1000 mcg/kg/day). In an embryo/fetal development study with pregnant mice that received the combination of subcutaneous administration of fluticasone propionate and oral administration of salmeterol at doses of 0/1400, 40/0, 10/200, 40/1400, or 150/10,000 mcg/kg/day (as fluticasone propionate/salmeterol) during the period of organogenesis, findings were generally consistent with the individual monoproducts and there was no exacerbation of expected fetal effects. Cleft palate, fetal death, increased implantation loss, and delayed ossification were observed in mouse fetuses when combining fluticasone propionate at a dose approximately 1.4 times the MRHDID (on a mcg/m 2 basis at a maternal subcutaneous dose of 150 mcg/kg/day) and salmeterol at a dose approximately 1470 times the MRHDID (on a mcg/m 2 basis at a maternal oral dose of 10,000 mcg/kg/day). No developmental toxicity was observed at combination doses of fluticasone propionate up to approximately 0.8 times the MRHDID (on a mcg/m 2 basis at a maternal subcutaneous dose of 40 mcg/kg) and doses of salmeterol up to approximately 420 times the MRHDID (on a mcg/m 2 basis at a maternal oral dose of 1400 mcg/kg). Fluticasone Propionate: In embryo/fetal development studies with pregnant rats and mice dosed by the subcutaneous route throughout the period of organogenesis, fluticasone propionate was teratogenic in both species. Omphalocele, decreased body weight, and skeletal variations were observed in rat fetuses, in the presence of maternal toxicity, at a dose approximately 2 times the MRHDID (on a mcg/m 2 basis with a maternal subcutaneous dose of 100 mcg/kg/day). The rat NOAEL was observed at approximately 0.6 times the MRHDID (on a mcg/m 2 basis with a maternal subcutaneous dose of 30 mcg/kg/day). Cleft palate and fetal skeletal variations were observed in mouse fetuses at a dose approximately 0.5 times the MRHDID (on a mcg/m 2 basis with a maternal subcutaneous dose of 45 mcg/kg/day). The mouse NOAEL was observed with a dose approximately 0.16 times the MRHDID (on a mcg/m 2 basis with a maternal subcutaneous dose of 15 mcg/kg/day). In an embryo/fetal development study with pregnant rats dosed by the inhalation route throughout the period of organogenesis, fluticasone propionate produced decreased fetal body weights and skeletal variations, in the presence of maternal toxicity, at a dose approximately 0.5 times the MRHDID (on a mcg/m 2 basis with a maternal inhalation dose of 25.7 mcg/kg/day); however, there was no evidence of teratogenicity. The NOAEL was observed with a dose approximately 0.1 times the MRHDID (on a mcg/m 2 basis with a maternal inhalation dose of 5.5 mcg/kg/day). In an embryo/fetal development study in pregnant rabbits that were dosed by the subcutaneous route throughout organogenesis, fluticasone propionate produced reductions of fetal body weights, in the presence of maternal toxicity at doses approximately 0.02 times the MRHDID and higher (on a mcg/m 2 basis with a maternal subcutaneous dose of 0.57 mcg/kg/day). Teratogenicity was evident based upon a finding of cleft palate for 1 fetus at a dose approximately 0.2 times the MRHDID (on a mcg/m 2 basis with a maternal subcutaneous dose of 4 mcg/kg/day). The NOAEL was observed in rabbit fetuses with a dose approximately 0.004 times the MRHDID (on a mcg/m 2 basis with a maternal subcutaneous dose of 0.08 mcg/kg/day). In a pre- and post-natal development study in pregnant rats dosed by the subcutaneous route from late gestation through delivery and lactation (Gestation Day 17 to Postpartum Day 22), fluticasone propionate was not associated with decreases in pup body weight, and had no effects on developmental landmarks, learning, memory, reflexes, or fertility at doses up to approximate equivalence to the MRHDID (on a mcg/m 2 basis with maternal subcutaneous doses up to 50 mcg/kg/day). Fluticasone propionate crossed the placenta following subcutaneous administration to mice and rats and oral administration to rabbits. Salmeterol: In three embryo/fetal development studies, pregnant rabbits received oral administration of salmeterol at doses ranging from 100 to 10,000 mcg/kg/day during the period of organogenesis. In pregnant Dutch rabbits administered salmeterol doses approximately 700 times the MRHDID (on a mcg/m 2 basis at maternal oral doses of 1000 mcg/kg/day and higher), fetal toxic effects were observed characteristically resulting from beta‑adrenoceptor stimulation. These included precocious eyelid openings, cleft palate, sternebral fusion, limb and paw flexures, and delayed ossification of the frontal cranial bones. No such effects occurred at a salmeterol dose approximately 420 times the MRHDID (on a mcg/m 2 basis at a maternal oral dose of 600 mcg/kg/day). New Zealand White rabbits were less sensitive since only delayed ossification of the frontal cranial bones was seen at a salmeterol dose approximately 7,000 times the MRHDID (on a mcg/m 2 basis at a maternal oral dose of 10,000 mcg/kg/day). In two embryo/fetal development studies, pregnant rats received salmeterol by oral administration at doses ranging from 100 to 10,000 mcg/kg/day during the period of organogenesis. Salmeterol produced no maternal toxicity or embryo/fetal effects at doses up to 3500 times the MRHDID (on a mcg/m 2 basis at maternal oral doses up to 10,000 mcg/kg/day). In a peri-and post-natal development study in pregnant rats dosed by the oral route from late gestation through delivery and lactation, salmeterol at a dose 3500 times the MRHDID (on mcg/m 2 basis with a maternal oral dose of 10,000 mcg/kg/day) was fetotoxic and decreased the fertility of survivors. Salmeterol xinafoate crossed the placenta following oral administration to mice and rats. 8.2 Lactation Risk Summary There are no available data on the presence of fluticasone propionate or salmeterol in human milk, the effects on the breastfed child, or the effects on milk production. Other corticosteroids have been detected in human milk. However, fluticasone propionate and salmeterol concentrations in plasma after inhaled therapeutic doses are low and therefore concentrations in human breast milk are likely to be correspondingly low [see Clinical Pharmacology (12.3)] . The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Fluticasone Propionate/Salmeterol MDPI and any potential adverse effects on the breastfed child from Fluticasone Propionate/Salmeterol MDPI or from the underlying maternal condition. Data Animal Data Subcutaneous administration of tritiated fluticasone propionate at a dose in lactating rats approximately 0.2 times the MRHDID for adults (on a mcg/m 2 basis) resulted in measurable levels in milk. Oral administration of salmeterol at a dose in lactating rats approximately 2900 times the MRHDID for adults (on a mcg/m 2 basis) resulted in measurable levels in milk . 8.4 Pediatric Use The safety and effectiveness of Fluticasone Propionate/Salmeterol MDPI have been established for the treatment of asthma in pediatric patients aged 12 years and older whose asthma (1) is inadequately controlled on a long term asthma control medication or (2) warrants initiation of treatment with both an ICS and a LABA. Use of Fluticasone Propionate/Salmeterol MDPI in pediatric patients aged 12 to 17 years for this indication is supported by evidence from two adequate and well-controlled trials in pediatric patients 12 years old and older with persistent symptomatic asthma despite ICS or ICS/LABA therapy (Trials 1 and 2) [see Clinical Studies ( 14 )]. In these trials, 58 adolescents received Fluticasone Propionate/Salmeterol MDPI one inhalation twice daily. The safety and effectiveness of Fluticasone Propionate/Salmeterol MDPI have not been established in pediatric patients younger than 12 years of age for the treatment of asthma. Effectiveness was not demonstrated in one adequate and well-controlled study conducted in 211 patients aged 4 to 11 years with persistent asthma on a stable asthma regimen who were treated with Fluticasone Propionate/Salmeterol MDPI 55 mcg/14 mcg one inhalation twice daily. Effect on Growth Inhaled corticosteroids, including fluticasone propionate, a component of this product, may cause a reduction in growth velocity in adolescents [see Warning and Precautions ( 5.13 )] . The growth of pediatric patients receiving ICS, including Fluticasone Propionate/Salmeterol MDPI, should be monitored. If an adolescent on any corticosteroid appears to have growth suppression, the possibility that he/she is particularly sensitive to this effect of corticosteroids should be considered. In such patients, the potential growth effects of prolonged ICS treatment should be weighed against the clinical benefits obtained. To minimize the systemic effects of ICS, including Fluticasone Propionate/Salmeterol MDPI, each patient should be titrated to the lowest strength that effectively controls his/her asthma [see Dosage and Administration ( 2 )]. 8.5 Geriatric Use No overall differences in safety or effectiveness were observed in data collected in 54 subjects aged 65 years and older versus younger subjects who were treated with Fluticasone Propionate/Salmeterol MDPI in placebo-controlled Phase 2 and 3 asthma studies. 8.6 Hepatic Impairment Formal pharmacokinetic studies using Fluticasone Propionate/Salmeterol MDPI have not been conducted in patients with hepatic impairment. However, since both fluticasone propionate and salmeterol are predominantly cleared by hepatic metabolism [see Clinical Pharmacology ( 12.3 )] , impairment of liver function may lead to accumulation of fluticasone propionate and salmeterol in plasma. Therefore, patients with hepatic impairment should be closely monitored. 8.7 Renal Impairment Formal pharmacokinetic studies using Fluticasone Propionate/Salmeterol MDPI have not been conducted in patients with renal impairment.
