⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Candida albicans infection of the mouth and pharynx. Monitor patients periodically for signs of adverse effects in the mouth and pharynx. After administration, advise patients to rinse mouth with water and spit out contents without swallowing.
( 5.1 ) Deterioration of asthma or acute episodes: ASMANEX TWISTHALER should not be used for relief of acute symptoms. Patients require immediate re-evaluation during rapidly deteriorating asthma. ( 5.2 ) Hypersensitivity reactions including anaphylaxis, angioedema, pruritus, and rash have been reported with the use of ASMANEX TWISTHALER.
Discontinue ASMANEX TWISTHALER if such reactions occur. ( 5.3 ) Potential worsening of existing tuberculosis; fungal, bacterial, viral, or parasitic infection; or ocular herpes simplex. More serious or even fatal course of chickenpox or measles in susceptible patients.
Use caution in patients with the above because of the potential for worsening of these infections. ( 5.4 ) Risk of impaired adrenal function when transferring from oral steroids to inhaled corticosteroids. Taper patients slowly from systemic corticosteroids if transferring to ASMANEX TWISTHALER.
( 5.5 ) Hypercorticism, suppression of hypothalamic-pituitary-adrenal (HPA) function, with very high dosages or at the regular dosage in susceptible individuals. If such changes occur discontinue ASMANEX TWISTHALER slowly. ( 5.6 ) Reduction in bone mineral density with long-term administration.
Monitor patients with major risk factors for decreased bone mineral content. ( 5.7 ) Suppression of growth in children. Monitor growth routinely in pediatric patients receiving ASMANEX TWISTHALER.
( 5.8 ) Glaucoma and cataracts. Consider referral to an ophthalmologist in patients who develop ocular symptoms or use ASMANEX TWISTHALER long term. ( 5.9 ) Paradoxical bronchospasm may occur with ASMANEX TWISTHALER.
Treat bronchospasm immediately with a fast-acting inhaled bronchodilator and discontinue use of ASMANEX TWISTHALER. ( 5.10 ) Strong cytochrome P450 3A4 inhibitors (e.g., ritonavir): Risk of increased systemic corticosteroid effects. Exercise caution when used with ASMANEX TWISTHALER.
( 5.11 )
5.1Oropharyngeal Candidiasis In clinical trials, the development of localized infections of the mouth and pharynx with Candida albicans occurred in 195 of 3007 patients treated with ASMANEX TWISTHALER. If oropharyngeal candidiasis develops, it should be treated with appropriate local or systemic (i.e., oral) antifungal therapy while remaining on treatment with ASMANEX TWISTHALER therapy, but at times therapy with the ASMANEX TWISTHALER may need to be interrupted. After administration, advise patients to rinse the mouth with water and spit out contents without swallowing.
5.2Acute Asthma Episodes ASMANEX TWISTHALER is not a bronchodilator and is not indicated for rapid relief of bronchospasm or other acute episodes of asthma. A short acting beta 2 -agonist, such as albuterol, should be available at all times to treat acute asthma symptoms. Instruct patients to contact their physician immediately if episodes of asthma that are not responsive to bronchodilators occur during the course of treatment with ASMANEX TWISTHALER.
During such episodes, patients may require therapy with oral corticosteroids.
5.3Hypersensitivity Reactions Including Anaphylaxis Hypersensitivity reactions including rash, pruritus, angioedema, and anaphylactic reaction have been reported with use of ASMANEX TWISTHALER. Discontinue ASMANEX TWISTHALER if such reactions occur [see Contraindications (4) and Adverse Reactions (6.2) ]. ASMANEX TWISTHALER contains small amounts of lactose, which contains trace levels of milk proteins.
In postmarketing experience with ASMANEX TWISTHALER, anaphylactic reactions in patients with milk protein allergy have been reported [see Contraindications (4) and Adverse Reactions (6.2) ].

6.1Clinical Studies Experience The safety data described below reflect exposure to ASMANEX TWISTHALER in 2380 patients with asthma exposed for 8 to 12 weeks and 627 patients with asthma exposed for 1 year in a total of 17 clinical trials. In adult and adolescent patients 12 years of age and older, ASMANEX TWISTHALER was studied in 10 placebo-controlled clinical trials of 8 to 12 weeks duration with a total of 1750 patients receiving ASMANEX TWISTHALER. There were also 3 trials with a total of 475 patients receiving ASMANEX TWISTHALER for 1 year.
In the 8- to 12-week clinical trials, the population was 12 to 83 years of age; 38% males and 62% females; and 83% Caucasian, 8% black, 6% Hispanic, and 3% other race/ethnicity. Patients received ASMANEX TWISTHALER 110 mcg twice daily (n=133), 220 mcg once daily in the morning (n=209), 220 mcg once daily in the evening (n=232), 220 mcg twice daily (n=433), 440 mcg once daily in the morning (n=419), 440 mcg once daily in the evening (n=250), or 440 mcg twice daily (n=74). In 3 long-term safety trials (two 9-month extensions of efficacy trials and one 52-week active-controlled safety trial), 475 patients with asthma (12-83 years of age, 44% males, 56% females, 87% Caucasian, 8% black, 4% Hispanic, and 1% other race/ethnicity) received various doses of ASMANEX TWISTHALER for 1 year.
In pediatric patients 4 to 11 years of age, ASMANEX TWISTHALER was studied in 3 placebo-controlled clinical trials of 12 weeks duration with a total of 630 patients receiving ASMANEX TWISTHALER and a 52-week, active-controlled safety trial with a total of 152 patients receiving ASMANEX TWISTHALER. In the 12-week clinical trials, the population was 4 to 11 years of age; 63% males and 37% females; and 67% Caucasian, 13% black, 17% Hispanic, and 3% other race/ethnicity. Patients received ASMANEX TWISTHALER 110 mcg once daily in the evening (n=98), 110 mcg once daily in the morning (n=181), 110 mcg twice daily (n=179), or 220 mcg once daily in the morning (n=172).
In the long-term active-controlled safety trial (n=152), patients with asthma (4 to 11 years of age, 60% males and 40% females, 84% Caucasian, 11% Black, and 5% Hispanic) received ASMANEX TWISTHALER 110 mcg twice daily or 220 mcg once daily in the morning for 52 weeks. Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
Adults and Adolescents 12 Years of Age and Older: The safety results of the 10 trials that were 8 to 12 weeks in duration were pooled because patients with asthma in these studies were previously maintained on bronchodilators and/or inhaled corticosteroids. The safety results of the one 12-week clinical trial in patients with asthma previously treated with oral corticosteroids are presented separately. In the pooled 8- to 12-week clinical trials, adverse reactions were reported in 70% of patients tr… [Excerpted — this section continues on DailyMed.]
🔄 Drug Interactions ▾
7 DRUG INTERACTIONS In clinical studies, the concurrent administration of ASMANEX TWISTHALER and other drugs commonly used in the treatment of asthma was not associated with any unusual adverse reactions. Strong cytochrome P450 3A4 inhibitors (e.g., ritonavir): Use with caution. May cause increased systemic corticosteroid effects. ( 7.1 )
7.1Inhibitors of Cytochrome P450 3A4 Concomitant administration of CYP3A4 inhibitors may inhibit the metabolism of, and increase the systemic exposure to, mometasone furoate and potentially increase the risk for systemic corticosteroid side effects [see Clinical Pharmacology (12.3) ] . Caution should be exercised when considering the coadministration of ASMANEX TWISTHALER with long-term ketoconazole and other known strong CYP3A4 inhibitors (e.g., ritonavir, cobicistat-containing products, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, saquinavir, telithromycin).
Consider the benefit of coadministration versus the potential risk of systemic corticosteroid effects, in which case patients should be monitored for systemic corticosteroid side effects.
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS
8.1Pregnancy Risk Summary There are no adequate and well-controlled studies of ASMANEX TWISTHALER in pregnant women. There are clinical considerations with the use of ASMANEX TWISTHALER in pregnant women [see Clinical Considerations ] . In animal reproduction studies with pregnant mice, rats, or rabbits, mometasone furoate caused increased fetal malformations and decreased fetal survival and growth following administration of doses that produced exposures approximately 1/3 to 8 times the maximum recommended human dose (MRHD) on a mcg/m 2 or AUC basis [see Data ] .
However, experience with oral corticosteroids suggests that rodents are more prone to teratogenic effects from corticosteroid exposure than humans. The estimated background 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 In an embryofetal development study with pregnant mice dosed throughout the period of organogenesis, mometasone furoate produced cleft palate at an exposure approximately 1/3 of the MRHD (on a mcg/m 2 basis with maternal subcutaneous doses of 60 mcg/kg and above) and decreased fetal survival at an exposure approximately equivalent to the MRHD (on a mcg/m 2 basis with a maternal subcutaneous dose of 180 mcg/kg).
No toxicity was observed with a dose that produced an exposure approximately 1/10 of the MRHD (on a mcg/m 2 basis with maternal topical dermal doses of 20 mcg/kg and above). In an embryofetal development study with pregnant rats dosed throughout the period of organogenesis, mometasone furoate produced fetal umbilical hernia at exposures approximately 6 times the MRHD (on a mcg/m 2 basis with maternal topical dermal doses of 600 mcg/kg and above) and delays in fetal ossification at exposures approximately 3 times the MRHD (on a mcg/m 2 basis with maternal topical dermal doses of 300 mcg/kg and above).
In another reproductive toxicity study, pregnant rats were dosed with mometasone furoate throughout pregnancy or late in gestation. Treated animals had prolonged and difficult labor, fewer live births, lower birth weight, and reduced early pup survival at an exposure that was approximately 6 times the MRHD (on an area under the curve (AUC) basis with a maternal subcutaneous dose of 15 mcg/kg). There were no findings with an exposure approximately 3 times the MRHD (on an AUC basis with a maternal subcutaneous dose of 7.5 mcg/kg).
Embryofetal development studies were conducted with pregnant rabbits dosed with mometasone furoate by either the topical dermal route or oral route throughout the period of organogenesis. In the study using the topical dermal route, mometasone furoate caused multiple malformations in fetuses (e.g., flexed front paws, gallbladder agenesis, umbilical hernia, hydrocephaly) at an exposure approximately 3 times the MRHD (on a mcg/m 2 basis with maternal topical dermal doses of 150 mcg/kg and above). In the study using the oral route, mometasone furoate caused increased fetal resorptions and cleft palate and/or head malformations (hydrocephaly and domed head) at an exposure approximately 1/2 of the MRHD (on an AUC basis with a maternal oral dose of 700 mcg/kg).
At an exposure approximately 2 times the MRHD (on an AUC basis with a maternal oral dose of 2800 mcg/kg), most litters were aborted or resorbed. No effects were observed at an exposure approxi… [Excerpted — this section continues on DailyMed.]

8.4Pediatric Use The safety and effectiveness of ASMANEX TWISTHALER for maintenance treatment of asthma as prophylactic therapy have been established in children 4 years of age and older. Use of ASMANEX TWISTHALER in pediatric patients 12 years of age and older is supported by evidence from adequate and well-controlled clinical trials in this patient population [see Clinical Studies (14.1) and Adverse Reactions (6.1) ] . Use of ASMANEX TWISTHALER in pediatric patients 4 to 11 years of age is supported by evidence from adequate and well-controlled clinical trials of 12 weeks duration in 630 patients 4 to 11 years of age receiving ASMANEX TWISTHALER and one 52-week safety trial in 152 patients [see Clinical Studies (14.1) and Adverse Reactions (6.1) ] .
Controlled clinical studies have shown that inhaled corticosteroids may cause a reduction in growth in pediatric patients. In these studies, the mean reduction in growth velocity was approximately 1 cm per year (range: 0.3–1.8 per year) and appears to depend upon dose and duration of exposure. This effect was observed in the absence of laboratory evidence of HPA axis suppression, suggesting that growth velocity is a more sensitive indicator of systemic corticosteroid exposure in pediatric patients than some commonly used tests of HPA axis function.
The long-term effects of this reduction in growth velocity associated with orally inhaled corticosteroids, including the impact on final adult height, are unknown. The potential for "catch-up" growth following discontinuation of treatment with orally inhaled corticosteroids has not been adequately studied. The growth of children and adolescents (4 years of age and older) receiving orally inhaled corticosteroids, including ASMANEX TWISTHALER, should be monitored routinely (e.g., via stadiometry).
A 52-week, placebo-controlled, parallel-group study was conducted to assess the potential growth effects of ASMANEX TWISTHALER in 187 prepubescent children (131 males and 56 females) 4 to 9 years of age with asthma who were previously maintained on an inhaled beta-agonist. Treatment groups included ASMANEX TWISTHALER 110 mcg twice daily (n=44), 220 mcg once daily in the morning (n=50), 110 mcg once daily in the morning (n=48), and placebo (n=45). For each patient, an average growth rate was determined using an individual regression approach.
The mean growth rates, expressed as least-squares mean in cm per year, for ASMANEX TWISTHALER 110 mcg twice daily, 220 mcg once daily in the morning, 110 mcg once daily in the morning, and placebo were 5.34, 5.93, 6.15, and 6.44, respectively. The differences from placebo and the corresponding 2-sided 95% CI of growth rates for ASMANEX TWISTHALER 110 mcg twice daily, 220 mcg once daily in the morning, and 110 mcg once daily in the morning were -1.11 (95% CI: -2.34, 0.12), -0.51 (95% CI: -1.69, 0.67), and -0.30 (95% CI: -1.48, 0.89), respectively.
The potential growth effects of prolonged treatment with orally inhaled corticosteroids should be weighed against clinical benefits obtained and the availability of safe and effective noncorticosteroid treatment alternatives. To minimize the systemic effects of orally inhaled corticosteroids, including ASMANEX TWISTHALER, each patient should be titrated to his/her lowest effective dose.
🧓 Geriatric Use ▾
8.5Geriatric Use A total of 175 patients 65 years of age and over (23 of whom were 75 years of age and older) have been treated with ASMANEX TWISTHALER in controlled clinical trials. No overall differences in safety or effectiveness were observed between these and younger patients, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.
🆘 Overdosage ▾
10 OVERDOSAGE Chronic overdosage may result in signs/symptoms of hypercorticism [see Warnings and Precautions (5.6) ]. Because of low systemic bioavailability and an absence of acute drug-related systemic findings in clinical studies, acute overdose is unlikely to require any treatment other than observation.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Mometasone furoate is a corticosteroid demonstrating potent anti-inflammatory activity. The precise mechanism of corticosteroid action on asthma is not known. Inflammation is an important component in the pathogenesis of asthma.
Corticosteroids have been shown to have a wide range of inhibitory effects 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 and in the asthmatic response. These anti-inflammatory actions of corticosteroids may contribute to their efficacy in asthma. Mometasone furoate has been shown in vitro to exhibit a binding affinity for the human glucocorticoid receptor, which is approximately 12 times that of dexamethasone, 7 times that of triamcinolone acetonide, 5 times that of budesonide, and 1.5 times that of fluticasone.
The clinical significance of these findings is unknown. Though effective for the treatment of asthma, corticosteroids do not affect asthma symptoms immediately. Maximum improvement in symptoms following inhaled administration of mometasone furoate may not be achieved for 1 to 2 weeks or longer after starting treatment.
When corticosteroids are discontinued, asthma stability may persist for several days or longer.
12.2Pharmacodynamics Adrenal Function: The effects of ASMANEX TWISTHALER on adrenal function have been evaluated in 2 clinical studies: 1 in adults 18 years of age and older and 1 in pediatric patients 6 to 11 years of age. Both clinical studies were specifically designed to assess the effect of ASMANEX TWISTHALER on adrenal function. In a 29-day, randomized, double-blind, placebo-controlled study in 64 adult and adolescent patients 18 years of age and older with asthma, ASMANEX TWISTHALER 440 mcg twice daily and 880 mcg twice daily (twice the highest recommended daily dose) were compared to both placebo and prednisone 10 mg once daily as a positive control.
The 30-minute post-Cosyntropin stimulation serum cortisol concentration on Day 29 was 23.2 mcg/dL for the ASMANEX 440 mcg twice daily group (n=16) and 20.8 mcg/dL for the ASMANEX 880 mcg twice daily group (n=16), compared to 14.5 mcg/dL for the oral prednisone 10-mg group (n=16) and 25 mcg/dL for the placebo group (n=16). The difference between ASMANEX 880 mcg twice daily (twice the maximum recommended dose) and placebo was statistically significant. In a 29-day, randomized, double-blind, placebo-controlled, parallel-group clinical trial in 50 pediatric patients 6 to 11 years of age with asthma, ASMANEX TWISTHALER 110 mcg twice daily, 220 mcg twice daily, and 440 mcg twice daily (2-8 times the highest pediatric daily recommended daily dose) were compared to placebo.
HPA-axis function was assessed by 12-hour plasma cortisol AUC and 24-hour urinary-free cortisol concentrations. After 29 days of treatment, the mean changes in plasma cortisol AUC 0–12h from baseline were -0.11, -19.5, -21.3, and -3.47 mcg•hr/dL for the treatment groups of ASMANEX TWISTHALER 110 mcg twice daily (n=12), 220 mcg twice daily (n=12), 440 mcg twice daily (n=11), and placebo (n=7), respectively. The mean differences from placebo in the groups treated with ASMANEX TWISTHALER 110 mcg twice daily, 220 mcg twice daily, and 440 mcg twice daily were 3.4 mcg•hr/dL (95% CI: -14.0, 20.7), -16.0 mcg•hr/dL (95% CI: -33.9, 1.9), and -17.9 mcg•hr/dL (95% CI: -35.8, 0.0), respectively.
For 24-hour urinary-free cortisol, after 29 days of treatment, the mean changes from baseline were -1.53, -1.33, -6.70, and -4.68 mcg/day for the groups treated with ASMANEX TWISTHALER 110 mcg twice daily (n=12), 220 mcg twice daily (n=12), 440 mcg twice daily (n=12), and placebo (n=10), respectively. The mean differences in urinary-free cortisol changes from baseline compared to placebo were 3.1 mcg/day (95% CI: -3.3, 9.6), 3.3 mcg/day (95% CI: -3.0, 9.7), and -2.0 mcg/day (95% CI: -8.6, 4.6)… [Excerpted — this section continues on DailyMed.]

📋 Description ▾
11 DESCRIPTION Mometasone furoate, the active component of the ASMANEX TWISTHALER product, is a corticosteroid with the chemical name 9,21-dichloro-11(Beta),17-dihydroxy-16(alpha)-methylpregna-1,4-diene-3,20-dione 17-(2-furoate) and the following chemical structure: Mometasone furoate is a white powder with an empirical formula of C 27 H 30 Cl 2 O 6 , and molecular weight of 521.44 Daltons. The ASMANEX TWISTHALER 110 mcg and 220 mcg products are cap-activated, inhalation-driven, multidose dry powder inhalers containing mometasone furoate and anhydrous lactose (which contains trace amounts of milk proteins).
Each actuation of the ASMANEX TWISTHALER 110 mcg or 220 mcg inhaler provides a measured dose of approximately 0.75 or 1.5 mg mometasone furoate inhalation powder, containing 110 or 220 mcg of mometasone furoate, respectively. This results in delivery of 100 or 200 mcg mometasone furoate from the mouthpiece, respectively, based on in vitro testing at flow rates of 30 L/min and 60 L/min with constant volume of 2 L. The amount of mometasone furoate emitted from the inhaler in vitro does not differ significantly for flow rates ranging from
28.3L/min to 70 L/min at a constant volume of 2 L. However, the amount of drug delivered to the lung will depend on patient factors such as inspiratory flow and peak inspiratory flow through the device. In adult and adolescent patients (aged ≥12 years) with varied asthma severity, mean peak inspiratory flow rate through the device was 69 L/min (range: 54–77 L/min).
In pediatric patients (aged 5-12 years) diagnosed with asthma, mean peak inspiratory flow rate in the 5- to 8-year-old subgroup was >50 L/min (minimum of 46 L/min) and for the 9- to 12-year-old subgroup was >60 L/min (minimum of 48 L/min). Chemical Structure
💬 Information for Patients ▾
17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling ( Patient Information and Instructions for Use ). Oropharyngeal Candidiasis Patients should be advised that localized infections with Candida albicans occurred in the mouth and pharynx in some patients. If oropharyngeal candidiasis develops, it should be treated with appropriate local or systemic (i.e., oral) antifungal therapy while still continuing with ASMANEX TWISTHALER therapy, but at times therapy with ASMANEX TWISTHALER may need to be temporarily interrupted under close medical supervision.
Rinsing the mouth after inhalation is advised [see Warnings and Precautions (5.1) ] . Acute Asthma Episodes Patients should be advised that ASMANEX TWISTHALER is not a bronchodilator and should not be used to treat status asthmaticus or to relieve acute asthma symptoms. Acute asthma symptoms should be treated with an inhaled, short-acting beta 2 -agonist such as albuterol [see Warnings and Precautions (5.2) ].
Hypersensitivity Reactions Including Anaphylaxis Hypersensitivity reactions including rash, pruritus, angioedema and anaphylactic reaction have been reported with use of ASMANEX TWISTHALER. Discontinue ASMANEX TWISTHALER if such reactions occur [see Contraindications (4) , Warnings and Precautions (5.3) , and Adverse Reactions (6.2) ]. ASMANEX TWISTHALER contains small amounts of lactose, which contains trace levels of milk proteins.
In postmarketing experience with ASMANEX TWISTHALER, anaphylactic reactions in patients with milk protein allergy have been reported [see Contraindications (4) and Adverse Reactions (6.2) ]. Immunosuppression and Risk of Infections Patients who are on immunosuppressant doses of corticosteroids should be warned to avoid exposure to chickenpox or measles and, if exposed, to consult their physician without delay. Patients should be informed of potential worsening of existing tuberculosis; fungal, bacterial, viral, or parasitic infections; or ocular herpes simplex [see Warnings and Precautions (5.4) ] .
Hypercorticism and Adrenal Suppression Patients should be advised that ASMANEX TWISTHALER may cause systemic corticosteroid effects of hypercorticism and adrenal suppression. Additionally, patients should be instructed 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 ASMANEX TWISTHALER [see Warnings and Precautions (5.6) ] .
Reduction in Bone Mineral Density Patients who are at an increased risk for decreased BMD should be advised that the use of corticosteroids may pose an additional risk and should be monitored and, where appropriate, be treated for this condition [see Warnings and Precautions (5.7) ] . Reduced Growth Velocity Patients should be informed that orally inhaled corticosteroids, including mometasone furoate inhalation powder, may cause a reduction in growth velocity when administered to pediatric patients. Physicians should closely follow the growth of children and adolescents taking corticosteroids by any route [see Warnings and Precautions (5.8) ] .
Use Daily for Best Effect Patients should be advised to use ASMANEX TWISTHALER at regular intervals, since its effectiveness depends on regular use. Maximum benefit may not be achieved for 1 to 2 weeks or longer after starting treatment. If symptoms do not improve in that time frame or if the condition worsens, patients should be instructed to contact their physician.
Instructions for Use Patients should be instructed to record the date of pouch opening on the cap label and discard the inhaler 45 days after opening the foil pouch or when the dose counter reads "00" and the final dose has been inhaled, whichever comes first. The inhaler should be held upright while removing the cap. The medication should be taken as directed, breathing rapidly and deeply, and patients should not breathe out through the inhaler.… [Excerpted — this section continues on DailyMed.]
🧬 Pharmacokinetics ▾
12.3Pharmacokinetics Absorption: Following a 1000 mcg inhaled dose of tritiated mometasone furoate inhalation powder to 6 healthy human subjects, plasma concentrations of unchanged mometasone furoate were shown to be very low compared to the total radioactivity in plasma. Following an inhaled single 400 mcg dose of ASMANEX TWISTHALER treatment to 24 healthy subjects, plasma concentrations for most subjects were near or below the lower limit of quantitation for the assay (50 pcg/mL). The mean absolute systemic bioavailability of the above single inhaled 400 mcg dose, compared to an intravenous 400 mcg dose of mometasone furoate, was determined to be less than 1%.
Following administration of the recommended highest inhaled dose (400 mcg twice daily) to 64 patients for 28 days, concentration-time profiles were discernible, but with large intersubject variability. The coefficient of variation for C max and AUC ranged from approximately 50% to 100%. The mean peak plasma concentrations at steady state ranged from approximately 94 to 114 pcg/mL and the mean time to peak levels ranged from approximately 1.0 to 2.5 hours.
Distribution: Based on the study employing a 1000 mcg inhaled dose of tritiated mometasone furoate inhalation powder in humans, no appreciable accumulation of mometasone furoate in the red blood cells was found. Following an intravenous 400 mcg dose of mometasone furoate, the plasma concentrations showed a biphasic decline, with a mean terminal half-life of about 5 hours and the mean steady-state volume of distribution of 152 L. The in vitro protein binding for mometasone furoate was reported to be 98% to 99% (in a concentration range of 5–500 ng/mL).
Elimination: Metabolism: Studies have shown that mometasone furoate is primarily and extensively metabolized in the liver of all species investigated and undergoes extensive metabolism to multiple metabolites. In vitro studies have confirmed the primary role of CYP3A4 in the metabolism of this compound; however, no major metabolites were identified. Excretion: Following an intravenous dosing, the terminal half-life was reported to be about 5 hours.
Following the inhaled dose of tritiated 1000 mcg mometasone furoate, the radioactivity is excreted mainly in the feces (a mean of 74%), and to a small extent in the urine (a mean of 8%) up to 7 days. No radioactivity was associated with unchanged mometasone furoate in the urine. Specific Populations: Pharmacokinetics have not been adequately investigated with ASMANEX TWISTHALER by gender, race or in pediatric patients.
Patients with Hepatic Impairment: Administration of a single inhaled dose of 400 mcg mometasone furoate to subjects with mild (n=4), moderate (n=4), and severe (n=4) hepatic impairment resulted in only 1 or 2 subjects in each group having detectable peak plasma concentrations of mometasone furoate (ranging from 50–105 pcg/mL). The observed peak plasma concentrations appear to increase with severity of hepatic impairment; however, the numbers of detectable levels were few. Patients with Renal Impairment: The effects of renal impairment on mometasone furoate pharmacokinetics have not been adequately investigated.
Drug Interaction Studies : Inhibitors of Cytochrome P450 3A4: In a drug interaction study, an inhaled dose of mometasone furoate 400 mcg was given to 24 healthy subjects twice daily for 9 days and ketoconazole 200 mg (as well as placebo) were given twice daily concomitantly on Days 4 to 9. Mometasone furoate plasma concentrations were <150 pcg/mL on Day 3 prior to coadministration of ketoconazole or placebo. Following concomitant administration of ketoconazole, 4 out of 12 subjects in the ketoconazole treatment group (n=12) had peak plasma concentrations of mometasone furoate >200 pcg/mL on Day 9 (211–324 pcg/mL).
🧬 Pharmacodynamics ▾
12.2Pharmacodynamics Adrenal Function: The effects of ASMANEX TWISTHALER on adrenal function have been evaluated in 2 clinical studies: 1 in adults 18 years of age and older and 1 in pediatric patients 6 to 11 years of age. Both clinical studies were specifically designed to assess the effect of ASMANEX TWISTHALER on adrenal function. In a 29-day, randomized, double-blind, placebo-controlled study in 64 adult and adolescent patients 18 years of age and older with asthma, ASMANEX TWISTHALER 440 mcg twice daily and 880 mcg twice daily (twice the highest recommended daily dose) were compared to both placebo and prednisone 10 mg once daily as a positive control.
The 30-minute post-Cosyntropin stimulation serum cortisol concentration on Day 29 was 23.2 mcg/dL for the ASMANEX 440 mcg twice daily group (n=16) and 20.8 mcg/dL for the ASMANEX 880 mcg twice daily group (n=16), compared to 14.5 mcg/dL for the oral prednisone 10-mg group (n=16) and 25 mcg/dL for the placebo group (n=16). The difference between ASMANEX 880 mcg twice daily (twice the maximum recommended dose) and placebo was statistically significant. In a 29-day, randomized, double-blind, placebo-controlled, parallel-group clinical trial in 50 pediatric patients 6 to 11 years of age with asthma, ASMANEX TWISTHALER 110 mcg twice daily, 220 mcg twice daily, and 440 mcg twice daily (2-8 times the highest pediatric daily recommended daily dose) were compared to placebo.
HPA-axis function was assessed by 12-hour plasma cortisol AUC and 24-hour urinary-free cortisol concentrations. After 29 days of treatment, the mean changes in plasma cortisol AUC 0–12h from baseline were -0.11, -19.5, -21.3, and -3.47 mcg•hr/dL for the treatment groups of ASMANEX TWISTHALER 110 mcg twice daily (n=12), 220 mcg twice daily (n=12), 440 mcg twice daily (n=11), and placebo (n=7), respectively. The mean differences from placebo in the groups treated with ASMANEX TWISTHALER 110 mcg twice daily, 220 mcg twice daily, and 440 mcg twice daily were 3.4 mcg•hr/dL (95% CI: -14.0, 20.7), -16.0 mcg•hr/dL (95% CI: -33.9, 1.9), and -17.9 mcg•hr/dL (95% CI: -35.8, 0.0), respectively.
For 24-hour urinary-free cortisol, after 29 days of treatment, the mean changes from baseline were -1.53, -1.33, -6.70, and -4.68 mcg/day for the groups treated with ASMANEX TWISTHALER 110 mcg twice daily (n=12), 220 mcg twice daily (n=12), 440 mcg twice daily (n=12), and placebo (n=10), respectively. The mean differences in urinary-free cortisol changes from baseline compared to placebo were 3.1 mcg/day (95% CI: -3.3, 9.6), 3.3 mcg/day (95% CI: -3.0, 9.7), and -2.0 mcg/day (95% CI: -8.6, 4.6) for the groups treated with 110 mcg twice daily, 220 mcg twice daily, and 440 mcg twice daily, respectively.
🔬 Clinical Studies ▾
14 CLINICAL STUDIES
14.1Asthma Adults and Adolescents 12 Years of Age and Older: The efficacy of ASMANEX TWISTHALER in patients with asthma 12 years and older was evaluated in ten 8- to 12-week, randomized, double-blind, placebo-controlled, parallel-group clinical trials. These trials included 1750 patients ranging from 12 to 83 years of age; 38% male and 62% female; and 83% Caucasian, 8% black, 6% Hispanic, and 3% other race/ethnicity. Patients received ASMANEX TWISTHALER 110 mcg twice daily (n=133), 220 mcg once daily in the morning (n=209), 220 mcg once daily in the evening (n=232), 220 mcg twice daily (n=433), 440 mcg once daily in the morning (n=419), 440 mcg once daily in the evening (n=250), or 440 mcg twice daily (n=74).
The results of the clinical trials are presented based upon previous asthma therapy. Patients ≥12 Years of Age Previously Maintained on Bronchodilators Alone: ASMANEX TWISTHALER was studied in three 12-week, double-blind trials in 737 patients with mild to moderate asthma (mean baseline FEV 1 ≅2.6 L, 72% of predicted normal) who were maintained on short-acting beta 2 -agonists alone. The first 2 trials evaluated doses of 440 mcg administered as 2 inhalations once daily in the morning and 1 of these studies also evaluated 220 mcg twice daily.
In both trials, morning predose FEV 1 was significantly improved at endpoint (last observation) following treatment with 440 mcg ASMANEX TWISTHALER once daily in the morning as compared to placebo (14% vs. 2.5%, respectively, in 1 trial and 16% vs. 5.5% in the other).
There was also a significant improvement in morning predose FEV 1 at endpoint following treatment with ASMANEX TWISTHALER 220 mcg twice daily. Other measures of lung function (morning and evening PEFR) also showed improvement compared to placebo. Patients receiving ASMANEX TWISTHALER treatment had reduced frequency of beta 2 -agonist rescue medication use compared to those on placebo (mean reductions at endpoint 2.2 and 0.5 puffs per day, respectively, from a baseline of 4.1 puffs/day).
Additionally, fewer patients receiving ASMANEX TWISTHALER 440 mcg once daily experienced asthma worsening than did patients receiving placebo. In the third trial, 195 asthmatic patients were treated with ASMANEX TWISTHALER 220 mcg once daily in the evening or placebo. The morning FEV 1 at endpoint was significantly improved compared to placebo (mean change at endpoint
0.43L or 16.8% vs.
0.16L or 6%, respectively, see Figure 1 ). Evening PEF increased
24.96 L/min (7%) from baseline in the ASMANEX TWISTHALER group compared to
8.67L/min (4%) in placebo. Figure Patients ≥12 Years of Age Previously Maintained on Inhaled Corticosteroids: The efficacy and safety of ASMANEX TWISTHALER in doses ranging from 110 mcg twice daily to 440 mcg twice daily was evaluated in 3 trials in 1072 patients previously maintained on inhaled corticosteroids. In the first 2 trials, asthmatic patients (mean baseline FEV 1 ~2.6 L, 76% predicted) were previously on either beclomethasone dipropionate [84–1200 mcg/day], flunisolide [100–2000 mcg/day], fluticasone propionate [110–880 mcg/day], or triamcinolone acetonide [300–2400 mcg/day].
The first trial included 307 patients who were treated in an open-label fashion with ASMANEX TWISTHALER 220 mcg (110 mcg × 2 inhalations) twice daily for 2 weeks followed by 12 weeks of double-blind treatment with ASMANEX TWISTHALER 440 mcg once daily in the morning or placebo. The second trial involved 365 patients who continued on their previous dose of inhaled corticosteroids during a 2-week screening period before being switched to ASMANEX TWISTHALER 440 mcg twice daily, 220 mcg twice daily, 110 mcg twice daily, beclomethasone dipropionate 168 mcg twice daily, or placebo for 12 weeks.
In the first trial, morning predose FEV 1 was effectively maintained (-1.4% change from baseline to endpoint) over the 12 weeks in the patients who were randomized to ASMANEX TWISTHALER 440 mcg once daily in the morning, while d… [Excerpted — this section continues on DailyMed.]

13 NONCLINICAL TOXICOLOGY
13.1Carcinogenesis, Mutagenesis, Impairment of Fertility In a 2-year carcinogenicity study in Sprague Dawley ® rats, mometasone furoate demonstrated no statistically significant increase in the incidence of tumors at inhalation doses up to 67 mcg/kg (approximately 8 times the maximum recommended daily inhalation dose in adults on an AUC basis and 2 times the maximum recommended daily inhalation dose in pediatric patients based on an mcg/m 2 basis). In a 19-month carcinogenicity study in Swiss CD-1 mice, mometasone furoate demonstrated no statistically significant increase in the incidence of tumors at inhalation doses up to 160 mcg/kg (approximately 10 times the maximum recommended daily inhalation dose in adults on an AUC basis and 2 times the maximum recommended daily inhalation dose in pediatric patients based on an mcg/m 2 basis).
Mometasone furoate increased chromosomal aberrations in an in vitro Chinese hamster ovary cell assay, but did not have this effect in an in vitro Chinese hamster lung cell assay. Mometasone furoate was not mutagenic in the Ames test or mouse lymphoma assay, and was not clastogenic in an in vivo mouse micronucleus assay, a rat bone marrow chromosomal aberration assay, or a mouse male germ-cell chromosomal aberration assay. Mometasone furoate also did not induce unscheduled DNA synthesis in vivo in rat hepatocytes.
In reproductive studies in rats, impairment of fertility was not produced by subcutaneous doses up to 15 mcg/kg (approximately 6 times the maximum recommended daily inhalation dose in adults on an AUC basis).
13.2Animal Toxicology and/or Pharmacology Reproductive Toxicology Studies: In mice, mometasone furoate caused cleft palate at subcutaneous doses of 60 mcg/kg and above (less than the maximum recommended daily inhalation dose in adults on an mcg/m 2 basis). Fetal survival was reduced at 180 mcg/kg (approximately equal to the maximum recommended daily inhalation dose in adults on an mcg/m 2 basis). No toxicity was observed at 20 mcg/kg (less than the maximum recommended daily inhalation dose in adults on an mcg/m 2 basis).
In rats, mometasone furoate produced umbilical hernia at topical dermal doses of 600 mcg/kg and above (approximately 6 times the maximum recommended daily inhalation dose in adults on an mcg/m 2 basis). A dose of 300 mcg/kg (approximately 3 times the maximum recommended daily inhalation dose in adults on an mcg/m 2 basis) produced delays in ossification but no malformations. When rats received subcutaneous doses of mometasone furoate throughout pregnancy or during the later stages of pregnancy, 15 mcg/kg (approximately 6 times the maximum recommended daily inhalation dose in adults on an AUC basis) caused prolonged and difficult labor and reduced the number of live births, birth weight, and early pup survival.
Similar effects were not observed at 7.5 mcg/kg (approximately 3 times the maximum recommended daily inhalation dose in adults on an AUC basis). In rabbits, mometasone furoate caused multiple malformations (e.g., flexed front paws, gallbladder agenesis, umbilical hernia, hydrocephaly) at topical dermal doses of 150 mcg/kg and above (approximately 3 times the maximum recommended daily inhalation dose in adults on an mcg/m 2 basis). In an oral study, mometasone furoate increased resorptions and caused cleft palate and/or head malformations (hydrocephaly and domed head) at 700 mcg/kg (less than the maximum recommended daily inhalation dose in adults on an area under the curve [AUC] basis).
At 2800 mcg/kg (approximately 2 times the maximum recommended daily inhalation dose in adults on an AUC basis) most litters were aborted or resorbed. No toxicity was observed at 140 mcg/kg (less than the maximum recommended daily inhalation dose in adults on an AUC basis).
📄 Carcinogenesis, Mutagenesis, Impairment of Fertility ▾
13.1Carcinogenesis, Mutagenesis, Impairment of Fertility In a 2-year carcinogenicity study in Sprague Dawley ® rats, mometasone furoate demonstrated no statistically significant increase in the incidence of tumors at inhalation doses up to 67 mcg/kg (approximately 8 times the maximum recommended daily inhalation dose in adults on an AUC basis and 2 times the maximum recommended daily inhalation dose in pediatric patients based on an mcg/m 2 basis). In a 19-month carcinogenicity study in Swiss CD-1 mice, mometasone furoate demonstrated no statistically significant increase in the incidence of tumors at inhalation doses up to 160 mcg/kg (approximately 10 times the maximum recommended daily inhalation dose in adults on an AUC basis and 2 times the maximum recommended daily inhalation dose in pediatric patients based on an mcg/m 2 basis).
Mometasone furoate increased chromosomal aberrations in an in vitro Chinese hamster ovary cell assay, but did not have this effect in an in vitro Chinese hamster lung cell assay. Mometasone furoate was not mutagenic in the Ames test or mouse lymphoma assay, and was not clastogenic in an in vivo mouse micronucleus assay, a rat bone marrow chromosomal aberration assay, or a mouse male germ-cell chromosomal aberration assay. Mometasone furoate also did not induce unscheduled DNA synthesis in vivo in rat hepatocytes.
In reproductive studies in rats, impairment of fertility was not produced by subcutaneous doses up to 15 mcg/kg (approximately 6 times the maximum recommended daily inhalation dose in adults on an AUC basis).
