Trelegy Ellipta

Maintenance Treatment of Chronic Obstructive Pulmonary Disease

TRELEGY ELLIPTA is indicated for the maintenance treatment of patients with chronic obstructive pulmonary disease (COPD).

Maintenance Treatment of Asthma

TRELEGY ELLIPTA is indicated for the maintenance treatment of asthma in patients aged 18 years and older.

Limitations of Use

TRELEGY ELLIPTA is NOT indicated for the relief of acute bronchospasm.

Dosage and Administration Overview

•

Administer 1 actuation of TRELEGY ELLIPTA once daily by oral inhalation.

•

After inhalation, rinse the mouth with water without swallowing to help reduce the risk of oropharyngeal candidiasis.

•

TRELEGY ELLIPTA should be used at the same time every day. Do not use TRELEGY ELLIPTA more than 1 time every 24 hours.

•

No dosage adjustment is required for geriatric patients, patients with renal impairment, or patients with moderate hepatic impairment [see Clinical Pharmacology ].

Recommended Dosage for Maintenance Treatment of Chronic Obstructive Pulmonary Disease

The recommended dosage of TRELEGY ELLIPTA for maintenance treatment of COPD is fluticasone furoate 100 mcg, umeclidinium 62.5 mcg, and vilanterol 25 mcg (1 actuation of TRELEGY ELLIPTA 100/62.5/25 mcg) once daily by oral inhalation.

•

TRELEGY ELLIPTA 100/62.5/25 mcg is the only strength indicated for the treatment of COPD.

•

If shortness of breath occurs in the period between doses, an inhaled, short-acting beta2-agonist (rescue medicine, e.g., albuterol) should be used for immediate relief.

Recommended Dosage for Maintenance Treatment of Asthma

The recommended starting dosage of TRELEGY ELLIPTA for maintenance treatment of asthma is fluticasone furoate 100 mcg, umeclidinium 62.5 mcg, and vilanterol 25 mcg (1 actuation of TRELEGY ELLIPTA 100/62.5/25 mcg) or fluticasone furoate 200 mcg, umeclidinium 62.5 mcg, and vilanterol 25 mcg (1 actuation of TRELEGY ELLIPTA 200/62.5/25 mcg) once daily, by oral inhalation.

•

When choosing the starting dosage strength of TRELEGY ELLIPTA, consider the patients’ disease severity; their previous asthma therapy, including the inhaled corticosteroid (ICS) dosage; as well as the patients’ current control of asthma symptoms and risk of future exacerbation.

•

The maximum recommended dosage is 1 inhalation of TRELEGY ELLIPTA 200/62.5/25 mcg once daily.

•

For patients who do not respond adequately to TRELEGY ELLIPTA 100/62.5/25 mcg once daily, increasing the dose to TRELEGY ELLIPTA 200/62.5/25 mcg once daily may provide additional improvement in asthma control. For patients who do not respond adequately to TRELEGY ELLIPTA 200/62.5/25 mcg once daily, re-evaluate and consider other therapeutic regimens and additional therapeutic options.

•

If asthma symptoms arise in the period between doses, an inhaled, short-acting beta2-agonist (rescue medicine, e.g., albuterol) should be used for immediate relief.

Pregnancy

Risk Summary

There are insufficient data on the use of TRELEGY ELLIPTA or its individual components, fluticasone furoate, umeclidinium, and vilanterol, in pregnant women to inform a drug‑associated risk. (See Clinical Considerations.) In an animal reproduction study, fluticasone furoate and vilanterol administered by inhalation alone or in combination to pregnant rats during the period of organogenesis produced no fetal structural abnormalities. The highest fluticasone furoate and vilanterol doses in this study were approximately 4.5 and 40 times the maximum recommended human daily inhalation doses (MRHDID) of 200 and 25 mcg, respectively in adults. (See Data.) Umeclidinium administered via inhalation or subcutaneously to pregnant rats and rabbits was not associated with adverse effect on embryofetal development at exposures approximately 40 and 150 times, respectively, the human exposure at the MRHDID of 62.5 mcg. (See Data.)

The estimated risk of major birth defects and miscarriage for the indicated populations 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 Embryofetal Risk: In women with poorly or moderately controlled asthma, there is an increased risk of several perinatal outcomes such as pre-eclampsia in the mother and prematurity, low birth weight, and small for gestational age in the neonate. Pregnant women should be closely monitored and medication adjusted as necessary to maintain optimal control of asthma.

Labor or Delivery: TRELEGY ELLIPTA should be used during late gestation and labor only if the potential benefit justifies the potential for risks related to beta-agonists interfering with uterine contractility.

Data

Animal Data: The combination of fluticasone furoate, umeclidinium, and vilanterol has not been studied in pregnant animals. Studies in pregnant animals have been conducted with fluticasone furoate and vilanterol in combination and individually with fluticasone furoate, umeclidinium, or vilanterol.

Fluticasone Furoate and Vilanterol: In an embryofetal developmental study, pregnant rats received fluticasone furoate and vilanterol during the period of organogenesis at doses up to approximately 4.5 and 40 times the MRHDID of 200 and 25 mcg, respectively, alone or in combination (on a mcg/m2 basis at inhalation doses up to approximately 95 mcg/kg/day). No evidence of structural abnormalities was observed.

Fluticasone Furoate: In 2 separate embryofetal developmental studies, pregnant rats and rabbits received fluticasone furoate during the period of organogenesis at doses up to approximately 4.5 times and equal to, respectively, the MRHDID of 200 mcg (on a mcg/m2 basis at maternal inhalation doses up to 91 and 8 mcg/kg/day, respectively). No evidence of structural abnormalities in fetuses was observed in either species. In a perinatal and postnatal developmental study in rats, dams received fluticasone furoate during late gestation and lactation periods at doses up to approximately 1.5 times the MRHDID of 200 mcg (on a mcg/m2 basis at maternal inhalation doses up to 27 mcg/kg/day). No evidence of effects on offspring development was observed.

Umeclidinium: In 2 separate embryofetal developmental studies, pregnant rats and rabbits received umeclidinium during the period of organogenesis at doses up to approximately 40 and 150 times, respectively the MRHDID of 62.5 mcg (on an AUC basis at maternal inhalation doses up to 278 mcg/kg/day in rats and at maternal subcutaneous doses up to 180 mcg/kg/day in rabbits). No evidence of teratogenic effects was observed in either species. In a perinatal and postnatal developmental study in rats, dams received umeclidinium during late gestation and lactation periods at doses up to approximately 20 times the MRHDID (on an AUC basis at maternal subcutaneous doses up to 60 mcg/kg/day). No evidence of effects on offspring development was observed.

Vilanterol: In 2 separate embryofetal developmental studies, pregnant rats and rabbits received vilanterol during the period of organogenesis at doses up to approximately 13,000 and 760 times, respectively, the MRHDID (on a mcg/m2 basis at maternal inhalation doses up to 33,700 mcg/kg/day in rats and on an AUC basis at maternal inhaled doses up to 5,740 mcg/kg/day in rabbits). No evidence of structural abnormalities was observed at any dose in rats or in rabbits up to approximately 120 times the MRHDID (on an AUC basis at maternal doses up to 591 mcg/kg/day). However, fetal skeletal variations were observed in rabbits at approximately 760 or 840 times the MRHDID (on an AUC basis at maternal inhaled or subcutaneous doses of 5,740 or 300 mcg/kg/day, respectively). The skeletal variations included decreased or absent ossification in cervical vertebral centrum and metacarpals. In a perinatal and postnatal developmental study in rats, dams received vilanterol during late gestation and the lactation periods at doses up to approximately 3,900 times the MRHDID (on a mcg/m2 basis at maternal oral doses up to 10,000 mcg/kg/day). No evidence of effects in offspring development was observed.

Lactation

Risk Summary

There is no information available on the presence of fluticasone furoate, umeclidinium, or vilanterol in human milk; the effects on the breastfed child; or the effects on milk production. Umeclidinium was detected in the plasma of offspring of lactating rats treated with umeclidinium, suggesting its presence in maternal milk. (See Data.) The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for TRELEGY ELLIPTA and any potential adverse effects on the breastfed child from fluticasone furoate, umeclidinium, or vilanterol or from the underlying maternal condition.

Data

Subcutaneous administration of umeclidinium to lactating rats at greater than or equal to 60 mcg/kg/day resulted in a quantifiable level of umeclidinium in 2 of 54 pups, which may indicate transfer of umeclidinium in rat milk.

Pediatric Use

The safety and effectiveness of TRELEGY ELLIPTA have not been established in pediatric patients (aged 17 years and younger). TRELEGY ELLIPTA is not indicated for use in pediatric patients.

Effects on Growth

Orally inhaled corticosteroids may cause a reduction in growth velocity when administered to children and adolescents.

Controlled clinical trials have shown that ICS may cause a reduction in growth in children. In these trials, the mean reduction in growth velocity was approximately 1 cm/year (range: 0.3 to 1.8 cm/year) and appears to be related to dose and duration of exposure. This effect has been 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 children 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.

A randomized, double-blind, parallel-group, multicenter, 1-year, placebo-controlled trial evaluated the effect of once-daily treatment with 110 mcg of fluticasone furoate in the nasal spray formulation on growth velocity assessed by stadiometry. The subjects were 474 prepubescent children (girls aged 5 to 7.5 years and boys aged 5 to 8.5 years). Mean growth velocity over the 52-week treatment period was lower in the subjects receiving fluticasone furoate nasal spray (5.19 cm/year) compared with placebo (5.46 cm/year). The mean reduction in growth velocity was 0.27 cm/year (95% CI: 0.06, 0.48) [see Warnings and Precautions ].

Geriatric Use

Based on available data, no adjustment of the dosage of TRELEGY ELLIPTA in geriatric patients is necessary, but greater sensitivity in some older individuals cannot be ruled out.

In COPD Trials 1 and 2 (coadministration trials), 189 subjects aged 65 years and older, of which 39 subjects were aged 75 years and older, were administered umeclidinium 62.5 mcg + fluticasone furoate/vilanterol 100/25 mcg. In COPD Trial 3, 2,265 subjects aged 65 years and older, of which 565 subjects were aged 75 years and older, were administered TRELEGY ELLIPTA. In an asthma clinical trial (Trial 4), 159 subjects aged 65 years and older, of which 27 subjects were aged 75 years and older, were administered TRELEGY ELLIPTA 100/62.5/25 mcg or TRELEGY ELLIPTA 200/62.5/25 mcg. No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger subjects.

Hepatic Impairment

TRELEGY ELLIPTA has not been studied in subjects with hepatic impairment. Information on the individual components is provided below.

Fluticasone Furoate/Vilanterol

Fluticasone furoate systemic exposure increased by up to 3-fold in subjects with hepatic impairment compared with healthy subjects. Hepatic impairment had no effect on vilanterol systemic exposure. Use TRELEGY ELLIPTA with caution in patients with moderate or severe hepatic impairment. Monitor patients for corticosteroid-related side effects [see Clinical Pharmacology ].

Umeclidinium

Patients with moderate hepatic impairment (Child-Pugh score of 7-9) showed no relevant increases in Cmax or AUC, nor did protein binding differ between subjects with moderate hepatic impairment and their healthy controls. Studies in subjects with severe hepatic impairment have not been performed [see Clinical Pharmacology ].

Renal Impairment

TRELEGY ELLIPTA has not been studied in subjects with renal impairment. Information on the individual components is provided below.

Fluticasone Furoate/Vilanterol

There were no significant increases in either fluticasone furoate or vilanterol exposure in subjects with severe renal impairment (CrCl <30 mL/min) compared with healthy subjects. No dosage adjustment is required in patients with renal impairment [see Clinical Pharmacology ].

Umeclidinium

Patients with severe renal impairment (CrCl <30 mL/min) showed no relevant increases in Cmax or AUC, nor did protein binding differ between subjects with severe renal impairment and their healthy controls. No dosage adjustment is required in patients with renal impairment [see Clinical Pharmacology ].

Serious Asthma-Related Events – Hospitalizations, Intubations, Death

Use of long-acting beta2-adrenergic agonists (LABA) as monotherapy (without ICS) for asthma is associated with an increased risk of asthma-related death. Available data from controlled clinical trials also suggest that use of LABA as monotherapy increases the risk of asthma-related hospitalization in pediatric and adolescent patients. These findings are considered a class effect of LABA monotherapy. When LABA are used in fixed‑dose combination with ICS, data from large clinical trials do not show a significant increase in the risk of serious asthma-related events (hospitalizations, intubations, death) compared with ICS alone (see Serious Asthma-Related Events with Inhaled Corticosteroid/Long‑acting Beta2-adrenergic Agonists).

Serious Asthma-Related Events with Inhaled Corticosteroid/Long-acting Beta2-adrenergic Agonists

Four (4) large, 26-week, randomized, double-blind, active-controlled clinical safety trials were conducted to evaluate the risk of serious asthma-related events when LABA were used in fixed-dose combination with ICS compared with ICS alone in subjects with asthma. Three (3) trials included adult and adolescent subjects aged 12 years and older: 1 trial compared budesonide/formoterol with budesonide, 1 trial compared fluticasone propionate/salmeterol inhalation powder with fluticasone propionate inhalation powder, and 1 trial compared mometasone furoate/formoterol with mometasone furoate. The fourth trial included pediatric subjects aged 4 to 11 years and compared fluticasone propionate/salmeterol inhalation powder with fluticasone propionate inhalation powder. The primary safety endpoint for all 4 trials was serious asthma-related events (hospitalizations, intubations, death). A blinded adjudication committee determined whether events were asthma related.

The 3 adult and adolescent trials were designed to rule out a risk margin of 2.0, and the pediatric trial was designed to rule out a risk margin of 2.7. Each individual trial met its pre-specified objective and demonstrated non-inferiority of ICS/LABA to ICS alone. A meta-analysis of the 3 adult and adolescent trials did not show a significant increase in risk of a serious asthma-related event with ICS/LABA fixed-dose combination compared with ICS alone . These trials were not designed to rule out all risk for serious asthma-related events with ICS/LABA compared with ICS.

The pediatric safety trial included 6,208 pediatric subjects aged 4 to 11 years who received ICS/LABA (fluticasone propionate/salmeterol inhalation powder) or ICS (fluticasone propionate inhalation powder). In this trial, 27/3,107 (0.9%) subjects randomized to ICS/LABA and 21/3,101 (0.7%) subjects randomized to ICS experienced a serious asthma-related event. There were no asthma-related deaths or intubations. ICS/LABA did not show a significantly increased risk of a serious asthma-related event compared with ICS based on the pre-specified risk margin (2.7), with an estimated hazard ratio of time to first event of 1.29 (95% CI: 0.73, 2.27). TRELEGY ELLIPTA is not indicated for use in pediatric patients aged 17 years and younger.

Salmeterol Multicenter Asthma Research Trial (SMART)

A 28-week, placebo-controlled, U.S. trial that compared the safety of salmeterol with placebo, each added to usual asthma therapy, showed an increase in asthma-related deaths in subjects receiving salmeterol (13/13,176 in subjects treated with salmeterol vs. 3/13,179 in subjects treated with placebo; relative risk: 4.37 [95% CI: 1.25, 15.34]). Use of background ICS was not required in SMART. The increased risk of asthma-related death is considered a class effect of LABA monotherapy.

Deterioration of Disease and Acute Episodes

TRELEGY ELLIPTA should not be initiated in patients during rapidly deteriorating or potentially life-threatening episodes of COPD or asthma. TRELEGY ELLIPTA has not been studied in subjects with acutely deteriorating COPD or asthma. The initiation of TRELEGY ELLIPTA in this setting is not appropriate.

If TRELEGY ELLIPTA 100/62.5/25 mcg no longer controls symptoms of bronchoconstriction; the patient’s inhaled, short-acting beta2-agonist becomes less effective; or the patient needs more short-acting beta2-agonist than usual, these may be markers of deterioration of disease. In this setting, re-evaluate the patient and the COPD treatment regimen at once. For COPD, the daily dose of TRELEGY ELLIPTA 100/62.5/25 mcg should not be increased.

Increasing use of inhaled, short-acting beta2-agonists is a marker of deteriorating asthma. In this situation, the patient requires immediate reevaluation with reassessment of the treatment regimen, giving special consideration to the need for additional therapeutic options. Patients should not use more than 1 inhalation once daily of TRELEGY ELLIPTA.

TRELEGY ELLIPTA should not be used for the relief of acute symptoms, i.e., as rescue therapy for the treatment of acute episodes of bronchospasm. TRELEGY ELLIPTA has not been studied in the relief of acute symptoms and extra doses should not be used for that purpose. Acute symptoms should be treated with an inhaled, short-acting beta2-agonist.

When beginning treatment with TRELEGY ELLIPTA, patients who have been taking oral or inhaled, short-acting beta2-agonists on a regular basis (e.g., 4 times a day) should be instructed to discontinue the regular use of these drugs and to use them only for symptomatic relief of acute respiratory symptoms. When prescribing TRELEGY ELLIPTA, the healthcare provider should also prescribe an inhaled, short-acting beta2-agonist and instruct the patient on how it should be used.

Avoid Excessive Use of TRELEGY ELLIPTA and Avoid Use with Other Long-acting Beta2-agonists

TRELEGY ELLIPTA should not be used more often than recommended, at higher doses than recommended, or in conjunction with other therapies containing LABA, as an overdose may result. Clinically significant cardiovascular effects and fatalities have been reported in association with excessive use of inhaled sympathomimetic drugs. Patients using TRELEGY ELLIPTA should not use another therapy containing a LABA (e.g., salmeterol, formoterol fumarate, arformoterol tartrate, indacaterol) for any reason.

Oropharyngeal Candidiasis

TRELEGY ELLIPTA contains fluticasone furoate, an ICS. Localized infections of the mouth and pharynx with Candida albicans have occurred in subjects treated with orally inhaled drug products containing fluticasone furoate. When such an infection develops, it should be treated with appropriate local or systemic (i.e., oral) antifungal therapy while treatment with TRELEGY ELLIPTA continues. In some cases, therapy with TRELEGY ELLIPTA may need to be interrupted. Advise the patient to rinse his/her mouth with water without swallowing following administration of TRELEGY ELLIPTA to help reduce the risk of oropharyngeal candidiasis.

Pneumonia

Lower respiratory tract infections, including pneumonia, have been reported following the inhaled administration of corticosteroids.

Physicians should remain vigilant for the possible development of pneumonia in patients with COPD as clinical features of pneumonia and exacerbations frequently overlap.

In two 12-week trials of subjects with COPD (N = 824), the incidence of pneumonia was <1% for both treatment arms: umeclidinium 62.5 mcg + fluticasone furoate/vilanterol 100/25 mcg or placebo + fluticasone furoate/vilanterol 100/25 mcg. Fatal pneumonia occurred in 1 subject receiving placebo + fluticasone furoate/vilanterol 100/25 mcg.

In a 52-week trial of subjects with COPD (N = 10,355), the incidence of pneumonia was 8% for TRELEGY ELLIPTA 100/62.5/25 mcg (n = 4,151), 7% for fluticasone furoate/vilanterol 100/25 mcg (n = 4,134), and 5% for umeclidinium/vilanterol 62.5/25 mcg (n = 2,070). Fatal pneumonia occurred in 12 of 4,151 patients (0.35 per 100 patient-years) receiving TRELEGY ELLIPTA 100/62.5/25 mcg; 5 of 4,134 patients (0.17 per 100 patient-years) receiving fluticasone furoate/vilanterol 100/25 mcg; and 5 of 2,070 patients (0.29 per 100 patient-years) receiving umeclidinium/vilanterol 62.5/25 mcg.

In a mortality trial with fluticasone furoate/vilanterol 100/25 mcg with a median treatment duration of 1.5 years in 16,568 subjects with moderate COPD and cardiovascular disease, the annualized incidence rate of pneumonia was 3.4 per 100 patient-years for fluticasone furoate/vilanterol 100/25 mcg, 3.2 for placebo, 3.3 for fluticasone furoate 100 mcg, and 2.3 for vilanterol 25 mcg. Adjudicated, on‑treatment deaths due to pneumonia occurred in 13 subjects receiving fluticasone furoate/vilanterol 100/25 mcg, 9 subjects receiving placebo, 10 subjects receiving fluticasone furoate 100 mcg, and 6 subjects receiving vilanterol 25 mcg (<0.2 per 100 patient-years for each treatment group).

Immunosuppression and Risk of Infections

Persons who are using drugs that suppress the immune system are more susceptible to infections than healthy individuals. Chickenpox and measles can have a more serious or even fatal course in susceptible children or adults using corticosteroids. In such children or adults who have not had these diseases or been properly immunized, particular care should be taken to avoid exposure. How the dose, route, and duration of corticosteroid administration affect the risk of developing a disseminated infection is not known. The safety and effectiveness of TRELEGY have not been established in pediatric patients and TRELEGY is not indicated for use in this population. The contribution of the underlying disease and/or prior corticosteroid treatment to the risk is also not known. If a patient is exposed to chickenpox, prophylaxis with varicella zoster immune globulin (VZIG) may be indicated. If a patient is exposed to measles, prophylaxis with pooled intramuscular immunoglobulin (IG) may be indicated. (See the respective Prescribing Information for VZIG and IG.) If chickenpox develops, treatment with antiviral agents may be considered.

ICS should be used with caution, if at all, in patients with active or quiescent tuberculosis infections of the respiratory tract; systemic fungal, bacterial, viral, or parasitic infections; or ocular herpes simplex.

Transferring Patients from Systemic Corticosteroid Therapy

HPA Suppression/Adrenal Insufficiency

Particular care is needed for patients who have been transferred from systemically active corticosteroids to ICS because deaths due to adrenal insufficiency have occurred in patients during and after transfer from systemic corticosteroids to less systemically available ICS. After withdrawal from systemic corticosteroids, a number of months are required for recovery of hypothalamic-pituitary-adrenal (HPA) function.

Patients who have been previously maintained on 20 mg or more of prednisone (or its equivalent) may be most susceptible, particularly when their systemic corticosteroids have been almost completely withdrawn. During this period of HPA suppression, patients may exhibit signs and symptoms of adrenal insufficiency when exposed to trauma, surgery, or infection (particularly gastroenteritis) or other conditions associated with severe electrolyte loss. Although TRELEGY ELLIPTA may control COPD or asthma symptoms during these episodes, in recommended doses it supplies less than normal physiological amounts of glucocorticoid systemically and does NOT provide the mineralocorticoid activity that is necessary for coping with these emergencies.

During periods of stress, a severe COPD exacerbation, or a severe asthma attack, patients who have been withdrawn from systemic corticosteroids should be instructed to resume oral corticosteroids (in large doses) immediately and to contact their health care practitioner for further instruction. These patients should also be instructed to carry a warning card indicating that they may need supplementary systemic corticosteroids during periods of stress, a severe COPD exacerbation, or a severe asthma attack.

Patients requiring oral corticosteroids should be weaned slowly from systemic corticosteroid use after transferring to TRELEGY ELLIPTA. Prednisone reduction can be accomplished by reducing the daily prednisone dose by 2.5 mg on a weekly basis during therapy with TRELEGY ELLIPTA. Lung function (FEV1), beta-agonist use, and COPD or asthma symptoms should be carefully monitored during withdrawal of oral corticosteroids. In addition, patients should be observed for signs and symptoms of adrenal insufficiency, such as fatigue, lassitude, weakness, nausea and vomiting, and hypotension.

Unmasking of Allergic Conditions Previously Suppressed by Systemic Corticosteroids

Transfer of patients from systemic corticosteroid therapy to TRELEGY ELLIPTA may unmask allergic conditions previously suppressed by the systemic corticosteroid therapy (e.g., rhinitis, conjunctivitis, eczema, arthritis, eosinophilic conditions).

Corticosteroid Withdrawal Symptoms

During withdrawal from oral corticosteroids, some patients may experience symptoms of systemically active corticosteroid withdrawal (e.g., joint and/or muscular pain, lassitude, depression) despite maintenance or even improvement of respiratory function.

Hypercorticism and Adrenal Suppression

Inhaled fluticasone furoate is absorbed into the circulation and can be systemically active. Effects of fluticasone furoate on the HPA axis are not observed with the therapeutic doses of fluticasone furoate in TRELEGY ELLIPTA. However, exceeding the recommended dosage or coadministration with a strong cytochrome P450 3A4 (CYP3A4) inhibitor may result in HPA dysfunction [see Warnings and Precautions , Drug Interactions ].

Because of the possibility of significant systemic absorption of ICS in sensitive patients, patients treated with TRELEGY ELLIPTA should be observed carefully for any evidence of systemic corticosteroid effects. Particular care should be taken in observing patients postoperatively or during periods of stress for evidence of inadequate adrenal response.

It is possible that systemic corticosteroid effects such as hypercorticism and adrenal suppression (including adrenal crisis) may appear in a small number of patients who are sensitive to these effects. If such effects occur, reduce the dose of TRELEGY ELLIPTA slowly, consistent with accepted procedures for reducing systemic corticosteroids, and consider other treatments for management of COPD or asthma symptoms.

Drug Interactions with Strong Cytochrome P450 3A4 Inhibitors

Caution should be exercised when considering the coadministration of TRELEGY ELLIPTA with ketoconazole and other known strong CYP3A4 inhibitors (including, but not limited to, ritonavir, clarithromycin, conivaptan, indinavir, itraconazole, lopinavir, nefazodone, nelfinavir, saquinavir, telithromycin, troleandomycin, voriconazole) because increased systemic corticosteroid and increased cardiovascular adverse effects may occur [see Drug Interactions , Clinical Pharmacology ].

Paradoxical Bronchospasm

As with other inhaled therapies, TRELEGY ELLIPTA can produce paradoxical bronchospasm, which may be life threatening. If paradoxical bronchospasm occurs following dosing with TRELEGY ELLIPTA, it should be treated immediately with an inhaled, short-acting bronchodilator; TRELEGY ELLIPTA should be discontinued immediately; and alternative therapy should be instituted.

Hypersensitivity Reactions, including Anaphylaxis

Hypersensitivity reactions such as anaphylaxis, angioedema, rash, and urticaria may occur after administration of TRELEGY ELLIPTA. Discontinue TRELEGY ELLIPTA if such reactions occur. There have been reports of anaphylactic reactions in patients with severe milk protein allergy after inhalation of other powder medications containing lactose; therefore, patients with severe milk protein allergy should not use TRELEGY ELLIPTA [see Contraindications , Adverse Reactions ].

Cardiovascular Effects

Vilanterol, like other beta2-agonists, can produce a clinically significant cardiovascular effect in some patients as measured by increases in pulse rate, systolic or diastolic blood pressure, and also cardiac arrhythmias, such as supraventricular tachycardia and extrasystoles. If such effects occur, TRELEGY ELLIPTA may need to be discontinued. In addition, beta-agonists have been reported to produce electrocardiographic changes, such as flattening of the T wave, prolongation of the QTc interval, and ST segment depression, although the clinical significance of these findings is unknown [see Clinical Pharmacology ]. Fatalities have been reported in association with excessive use of inhaled sympathomimetic drugs.

TRELEGY ELLIPTA, like other sympathomimetic amines, should be used with caution in patients with cardiovascular disorders, especially coronary insufficiency, cardiac arrhythmias, and hypertension.

In a 52-week trial of subjects with COPD, the exposure-adjusted rates for any on-treatment major adverse cardiac event, including non-fatal central nervous system hemorrhages and cerebrovascular conditions, non-fatal myocardial infarction (MI), non-fatal acute MI, and adjudicated on-treatment death due to cardiovascular events, was 2.2 per 100 patient-years for TRELEGY ELLIPTA (n = 4,151), 1.9 per 100 patient-years for fluticasone furoate/vilanterol 100/25 mcg (n = 4,134), and 2.2 per 100 patient-years for umeclidinium/vilanterol 62.5/25 mcg (n = 2,070). Adjudicated on-treatment deaths due to cardiovascular events occurred in 20 of 4,151 patients (0.54 per 100 patient-years) receiving TRELEGY ELLIPTA; 27 of 4,134 patients (0.78 per 100 patient-years) receiving fluticasone furoate/vilanterol; and 16 of 2,070 patients (0.94 per 100 patient-years) receiving umeclidinium/vilanterol.

In a mortality trial with fluticasone furoate/vilanterol with a median treatment duration of 1.5 years in 16,568 subjects with moderate COPD and cardiovascular disease, the annualized incidence rate of adjudicated cardiovascular events (composite of myocardial infarction, stroke, unstable angina, transient ischemic attack, or on-treatment death due to cardiovascular events) was 2.5 per 100 patient-years for fluticasone furoate/vilanterol 100/25 mcg, 2.7 for placebo, 2.4 for fluticasone furoate 100 mcg, and 2.6 for vilanterol 25 mcg. Adjudicated, on-treatment deaths due to cardiovascular events occurred in 82 subjects receiving fluticasone furoate/vilanterol 100/25 mcg, 86 subjects receiving placebo, 80 subjects receiving fluticasone furoate 100 mcg, and 90 subjects receiving vilanterol 25 mcg (annualized incidence rate ranged from 1.2 to 1.3 per 100 patient-years for the treatment groups).

Reduction in Bone Mineral Density

Decreases in bone mineral density (BMD) have been observed with long-term administration of products containing ICS. The clinical significance of small changes in BMD with regard to long‑term consequences such as fracture is unknown. Patients with major risk factors for decreased bone mineral content, such as prolonged immobilization, family history of osteoporosis, postmenopausal status, tobacco use, advanced age, poor nutrition, or chronic use of drugs that can reduce bone mass (e.g., anticonvulsants, oral corticosteroids) should be monitored and treated with established standards of care. Since patients with COPD often have multiple risk factors for reduced BMD, assessment of BMD is recommended prior to initiating TRELEGY ELLIPTA and periodically thereafter. If significant reductions in BMD are seen and TRELEGY ELLIPTA is still considered medically important for that patient’s COPD therapy, use of therapy to treat or prevent osteoporosis should be strongly considered.

Glaucoma and Cataracts, Worsening of Narrow-Angle Glaucoma

Glaucoma, increased intraocular pressure, and cataracts have been reported in patients with COPD or asthma following the long-term administration of ICS or with use of inhaled anticholinergics. TRELEGY ELLIPTA should be used with caution in patients with narrow-angle glaucoma. Prescribers and patients should also be alert for signs and symptoms of acute narrow‑angle glaucoma (e.g., eye pain or discomfort, blurred vision, visual halos or colored images in association with red eyes from conjunctival congestion and corneal edema). Instruct patients to consult a healthcare provider immediately if any of these signs or symptoms develop. Consider referral to an ophthalmologist in patients who develop ocular symptoms or use TRELEGY ELLIPTA long term.

Worsening of Urinary Retention

TRELEGY ELLIPTA, like all therapies containing an anticholinergic, should be used with caution in patients with urinary retention. Prescribers and patients should be alert for signs and symptoms of urinary retention (e.g., difficulty passing urine, painful urination), especially in patients with prostatic hyperplasia or bladder-neck obstruction. Instruct patients to consult a healthcare provider immediately if any of these signs or symptoms develop.

Coexisting Conditions

TRELEGY ELLIPTA, like all therapies containing sympathomimetic amines, should be used with caution in patients with convulsive disorders or thyrotoxicosis and in those who are unusually responsive to sympathomimetic amines. Doses of the related beta2-adrenoceptor agonist albuterol, when administered intravenously, have been reported to aggravate preexisting diabetes mellitus and ketoacidosis.

Hypokalemia and Hyperglycemia

Beta-adrenergic agonist therapies may produce significant hypokalemia in some patients, possibly through intracellular shunting, which has the potential to produce adverse cardiovascular effects. The decrease in serum potassium is usually transient, not requiring supplementation. Beta-agonist therapies may produce transient hyperglycemia in some patients.

Effect on Growth

Orally inhaled corticosteroids may cause a reduction in growth velocity when administered to children and adolescents. The safety and effectiveness of TRELEGY have not been established in pediatric patients (aged 17 years and younger) and TRELEGY is not indicated for use in this population. [See Use in Specific Populations .]

Clinical Trials Experience in Chronic Obstructive Pulmonary Disease

The safety of TRELEGY ELLIPTA in COPD is based on the safety data from two 12-week treatment trials with coadministration of umeclidinium and the fixed-dose combination of fluticasone furoate/vilanterol and a 52-week long-term trial of TRELEGY ELLIPTA 100/62.5/25 mcg compared with the fixed-dose combinations of fluticasone furoate/vilanterol and umeclidinium/vilanterol [see Clinical Studies ].

Trials 1 and 2

Two 12-week treatment trials (Trial 1 and Trial 2) evaluated the coadministration of umeclidinium + fluticasone furoate/vilanterol, the components of TRELEGY ELLIPTA, compared with placebo + fluticasone furoate/vilanterol. A total of 824 subjects with COPD across two 12-week, randomized, double-blind clinical trials received at least 1 dose of umeclidinium 62.5 mcg + fluticasone furoate/vilanterol 100/25 mcg or placebo + fluticasone furoate/vilanterol 100/25 mcg administered once daily (mean age: 64 years, 92% White, 66% male across all treatments) [see Clinical Studies ]. The incidence of adverse reactions associated with the use of umeclidinium 62.5 mcg + fluticasone furoate/vilanterol 100/25 mcg presented in Table 2 is based on the two 12-week trials.

Trial 3 – Long-term Safety Data

A 52-week trial (Trial 3) evaluated the long-term safety of TRELEGY ELLIPTA 100/62.5/25 mcg compared with the fixed-dose combinations of fluticasone furoate/vilanterol 100/25 mcg and umeclidinium/vilanterol 62.5/25 mcg. A total of 10,355 subjects with COPD with a history of moderate or severe exacerbations within the prior 12 months were randomized (2:2:1) to receive TRELEGY ELLIPTA 100/62.5/25 mcg, fluticasone furoate/vilanterol, or umeclidinium/vilanterol administered once daily in a double‑blind clinical trial (mean age: 65 years, 77% White, 66% male across all treatments) [see Clinical Studies ].

The incidence of adverse reactions in the long-term trial were consistent with those in Trials 1 and 2. However, in addition to the adverse reactions shown in Table 2, adverse reactions occurring in ≥1% of the subjects treated with TRELEGY ELLIPTA 100/62.5/25 mcg (n = 4,151) for up to 52 weeks also included upper respiratory tract infection, pneumonia [see Warnings and Precautions ], bronchitis, oral candidiasis [see Warnings and Precautions ], arthralgia, influenza, sinusitis, pharyngitis, rhinitis, constipation, urinary tract infection, and dysphonia.

Clinical Trials Experience in Asthma

The safety of TRELEGY ELLIPTA in asthma is based on a randomized, double-blind, parallel‑group, active-controlled trial of 24 to 52 weeks’ duration (Trial 4) that enrolled 2,436 adult subjects inadequately controlled on their current treatment of combination therapy (ICS plus a LABA) [see Clinical Studies ]. In the overall population, 62% were female and 80% were White; mean age was 53 years. The incidence of adverse reactions occurring in ≥1% of the subjects treated with TRELEGY ELLIPTA 100/62.5/25 mcg or TRELEGY ELLIPTA 200/62.5/25 mcg is shown in Table 3. Adverse reactions observed for the groups treated with TRELEGY ELLIPTA were similar to those observed for the fluticasone furoate/vilanterol arms.

Postmarketing Experience

In addition to adverse reactions reported from clinical trials, the following adverse reactions have been identified during postapproval use of TRELEGY ELLIPTA. 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 TRELEGY ELLIPTA or a combination of these factors.

Inhibitors of Cytochrome P450 3A4

Fluticasone furoate and vilanterol are substrates of CYP3A4. Concomitant administration of the strong CYP3A4 inhibitor ketoconazole increases the systemic exposure to fluticasone furoate and vilanterol. Caution should be exercised when considering the coadministration of TRELEGY ELLIPTA with ketoconazole and other known strong CYP3A4 inhibitors [see Warnings and Precautions , Clinical Pharmacology ].

Monoamine Oxidase Inhibitors, Tricyclic Antidepressants, and QTc Prolonging Drugs

Vilanterol, like other beta2-agonists, should be administered with extreme caution to patients being treated with monoamine oxidase inhibitors, tricyclic antidepressants, or drugs known to prolong the QTc interval or within 2 weeks of discontinuation of such agents, because the effect of adrenergic agonists on the cardiovascular system may be potentiated by these agents. Drugs that are known to prolong the QTc interval have an increased risk of ventricular arrhythmias.

Beta-adrenergic Receptor Blocking Agents

Beta-blockers not only block the pulmonary effect of beta-agonists, such as vilanterol, but may also produce severe bronchospasm in patients with COPD or asthma. Therefore, patients with COPD or 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.

Non–Potassium-Sparing Diuretics

The electrocardiographic changes and/or hypokalemia that may result from the administration of non–potassium-sparing diuretics (such as loop or thiazide diuretics) can be acutely worsened by beta-agonists, especially when the recommended dose of the beta-agonist is exceeded. Although the clinical significance of these effects is not known, caution is advised in the coadministration of beta-agonists with non–potassium-sparing diuretics.

Anticholinergics

There is potential for an additive interaction with concomitantly used anticholinergic medicines. Therefore, avoid coadministration of TRELEGY ELLIPTA with other anticholinergic-containing drugs as this may lead to an increase in anticholinergic adverse effects [see Warnings and Precautions ].

Mechanism of Action

TRELEGY ELLIPTA

TRELEGY ELLIPTA contains fluticasone furoate, umeclidinium, and vilanterol. The mechanisms of action described below for the individual components apply to TRELEGY ELLIPTA. These drugs represent 3 different classes of medications (an ICS, an anticholinergic, and a LABA), each having different effects on clinical and physiological indices.

Fluticasone Furoate

Fluticasone furoate is a synthetic trifluorinated corticosteroid with anti-inflammatory activity. Fluticasone furoate has been shown in vitro to exhibit a binding affinity for the human glucocorticoid receptor that is approximately 29.9 times that of dexamethasone and 1.7 times that of fluticasone propionate. The clinical relevance of these findings is unknown.

The precise mechanism through which fluticasone furoate affects COPD and asthma symptoms is not known. Inflammation is an important component in the pathogenesis of COPD and asthma. Corticosteroids have been shown to have a wide range of actions on multiple cell types (e.g., mast cells, eosinophils, neutrophils, macrophages, lymphocytes) and mediators (e.g., histamine, eicosanoids, leukotrienes, cytokines) involved in inflammation. Specific effects of fluticasone furoate demonstrated in in vitro and in vivo models included activation of the glucocorticoid response element, inhibition of pro-inflammatory transcription factors such as NFkB, and inhibition of antigen-induced lung eosinophilia in sensitized rats. These anti-inflammatory actions of corticosteroids may contribute to their efficacy.

Umeclidinium

Umeclidinium is a long-acting muscarinic antagonist, which is often referred to as an anticholinergic. It has similar affinity to the subtypes of muscarinic receptors M1 to M5. In the airways, it exhibits pharmacological effects through inhibition of M3 receptor at the smooth muscle leading to bronchodilation. The competitive and reversible nature of antagonism was shown with human and animal origin receptors and isolated organ preparations. In preclinical in vitro as well as in vivo studies, prevention of methacholine- and acetylcholine-induced bronchoconstrictive effects was dose-dependent and lasted longer than 24 hours. The clinical relevance of these findings is unknown. The bronchodilation following inhalation of umeclidinium is predominantly a site-specific effect.

Vilanterol

Vilanterol is a LABA. In vitro tests have shown the functional selectivity of vilanterol was similar to salmeterol. The clinical relevance of this in vitro finding is unknown.

Although beta2-receptors are the predominant adrenergic receptors in bronchial smooth muscle and beta1-receptors are the predominant receptors in the heart, there are also beta2-receptors in the human heart comprising 10% to 50% of the total beta-adrenergic receptors. The precise function of these receptors has not been established, but they raise the possibility that even highly selective beta2-agonists may have cardiac effects.

The pharmacologic effects of beta2-adrenergic agonist drugs, including vilanterol, are at least in part attributable to stimulation of intracellular adenyl cyclase, the enzyme that catalyzes the conversion of adenosine triphosphate (ATP) to cyclic-3ʹ,5ʹ-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.

Pharmacodynamics

Cardiac Electrophysiology

The effect of umeclidinium/vilanterol on cardiac rhythm in subjects diagnosed with COPD was assessed using 24-hour Holter monitoring in 6- and 12-month trials: 53 subjects received umeclidinium/vilanterol 62.5/25 mcg, 281 subjects received umeclidinium/vilanterol 125/25 mcg, and 182 subjects received placebo. No clinically meaningful effects on cardiac rhythm were observed.

The cardiovascular effects from dual combinations of fluticasone furoate/vilanterol and umeclidinium/vilanterol in healthy subjects are presented below.

Fluticasone Furoate/Vilanterol Combination: Healthy Subjects: QTc interval prolongation was studied in a double-blind, multiple-dose, placebo- and positive-controlled crossover study in 85 healthy volunteers. The maximum mean (95% upper confidence bound) difference in QTcF from placebo after baseline correction was 4.9 (7.5) milliseconds and 9.6 (12.2) milliseconds seen 30 minutes after dosing for fluticasone furoate/vilanterol 200/25 mcg and fluticasone furoate/vilanterol 800/100 mcg, respectively.

A dose-dependent increase in heart rate was also observed. The maximum mean (95% upper confidence bound) difference in heart rate from placebo after baseline correction was 7.8 (9.4) beats/min and 17.1 (18.7) beats/min seen 10 minutes after dosing for fluticasone furoate/vilanterol 200/25 mcg and fluticasone furoate/vilanterol 800/100 mcg (8/4 times the recommended dosage), respectively.

Umeclidinium/Vilanterol Combination: Healthy Subjects: QTc interval prolongation was studied in a double-blind, multiple-dose, placebo- and positive-controlled crossover trial in 86 healthy subjects. The maximum mean (95% upper confidence bound) difference in QTcF from placebo after baseline correction was 4.6 (7.1) milliseconds and 8.2 (10.7) milliseconds for umeclidinium/vilanterol 125/25 mcg and umeclidinium/vilanterol 500/100 mcg (8/4 times the recommended dosage), respectively.

A dose-dependent increase in heart rate was also observed. The maximum mean (95% upper confidence bound) difference in heart rate from placebo after baseline correction was 8.8 (10.5) beats/min and 20.5 (22.3) beats/min seen 10 minutes after dosing for umeclidinium/vilanterol 125/25 mcg and umeclidinium/vilanterol 500/100 mcg, respectively.

HPA Axis Effects

Healthy Subjects: Inhaled fluticasone furoate at repeat doses up to 400 mcg was not associated with statistically significant decreases in serum or urinary cortisol in healthy subjects. Decreases in serum and urine cortisol levels were observed at fluticasone furoate exposures several-fold higher than exposures observed at the therapeutic dose.

Subjects with Chronic Obstructive Pulmonary Disease: In a trial with subjects with COPD, treatment with fluticasone furoate (50, 100, or 200 mcg)/vilanterol 25 mcg, vilanterol 25 mcg, or fluticasone furoate (100 or 200 mcg) for 6 months did not affect 24-hour urinary cortisol excretion. A separate trial with subjects with COPD demonstrated no effects on serum cortisol after 28 days of treatment with fluticasone furoate (50, 100, or 200 mcg)/vilanterol 25 mcg.

Subjects with Asthma: A randomized, double-blind, parallel-group trial in 185 subjects with asthma showed no difference between once-daily treatment with fluticasone furoate/vilanterol 100/25 mcg or fluticasone furoate/vilanterol 200/25 mcg compared with placebo on serum cortisol weighted mean (0 to 24 hours), serum cortisol AUC(0-24), and 24-hour urinary cortisol after 6 weeks of treatment, whereas prednisolone 10 mg given once daily for 7 days resulted in significant cortisol suppression.

Pharmacokinetics

Linear pharmacokinetics was observed for fluticasone furoate (200 to 800 mcg), umeclidinium (62.5 to 500 mcg), and vilanterol (25 to 100 mcg). The pharmacokinetics of fluticasone furoate, umeclidinium, and vilanterol from TRELEGY ELLIPTA are comparable to the pharmacokinetics of fluticasone furoate, umeclidinium, and vilanterol when administered as fluticasone furoate/vilanterol or umeclidinium/vilanterol.

Systemic drug levels [steady-state Cmax and AUC(0-24)] of fluticasone furoate, umeclidinium, and vilanterol following administration of TRELEGY ELLIPTA 100/62.5/25 mcg based on a combined pharmacokinetic dataset from 3 studies in subjects with COPD (N = 821) were within the range of those observed following administration of fluticasone furoate/vilanterol plus umeclidinium administered via 2 inhalers, fluticasone furoate/vilanterol and umeclidinium/vilanterol as the dual combinations, and after administration of fluticasone furoate, umeclidinium, and vilanterol as monotherapy.

Systemic drug levels [steady-state Cmax and AUC(0-24)] of fluticasone furoate, umeclidinium, and vilanterol following administration of TRELEGY ELLIPTA (100/62.5/25 or 200/62.5/25 mcg) based on a population pharmacokinetic analysis from subjects with asthma (1,265 subjects for fluticasone furoate; 634 subjects for umeclidinium; 1,263 subjects for vilanterol) were within the range of those observed following administration of fluticasone furoate/vilanterol as the dual combination when compared with fluticasone furoate 100 and 200 mcg, respectively; the systemic exposure of umeclidinium 62.5 mcg following TRELEGY ELLIPTA (100/62.5/25 or 200/62.5/25 mcg) was within the range of those observed following administration of umeclidinium 62.5 mcg as monotherapy.

The pharmacokinetics of the individual components of TRELEGY ELLIPTA are presented as follows. Plasma levels of fluticasone furoate, umeclidinium, and vilanterol may not predict therapeutic effect.

Absorption

Fluticasone Furoate: Following inhaled administration of fluticasone furoate, Cmax occurred within 0.5 to 1 hour. Absolute bioavailability of fluticasone furoate when administered by inhalation was 15.2%, primarily due to absorption of the inhaled portion of the dose delivered to the lung. Oral bioavailability from the swallowed portion of the dose is low (approximately 1.3%) due to extensive first-pass metabolism. Following repeat dosing of inhaled fluticasone furoate, steady state was achieved within 6 days with up to 2.6-fold accumulation.

Umeclidinium: Following inhaled administration of umeclidinium in healthy subjects, Cmax occurred at 5 to 15 minutes. Umeclidinium is mostly absorbed from the lung after inhaled doses with minimum contribution from oral absorption. Following repeat dosing of inhaled umeclidinium, steady state was achieved within 14 days with up to 1.8-fold accumulation.

Vilanterol: Following inhaled administration of vilanterol in healthy subjects, Cmax occurred at 5 to 15 minutes. Vilanterol is mostly absorbed from the lung after inhaled doses with negligible contribution from oral absorption. Following repeat dosing of inhaled vilanterol, steady state was achieved within 14 days with up to 1.7-fold accumulation.

Distribution

Fluticasone Furoate: Following intravenous administration to healthy subjects, the mean volume of distribution at steady state was 661 L. Binding of fluticasone furoate to human plasma proteins was high (>99%).

Umeclidinium: Following intravenous administration to healthy subjects, the mean volume of distribution was 86 L. In vitro plasma protein binding in human plasma was on average 89%.

Vilanterol: Following intravenous administration to healthy subjects, the mean volume of distribution at steady state was 165 L. In vitro plasma protein binding in human plasma was on average 94%.

Elimination

Metabolism: Fluticasone Furoate: Fluticasone furoate is cleared from systemic circulation principally by hepatic metabolism via CYP3A4 to metabolites with significantly reduced corticosteroid activity. There was no in vivo evidence for cleavage of the furoate moiety resulting in the formation of fluticasone.

Umeclidinium: In vitro data showed that umeclidinium is primarily metabolized by the enzyme cytochrome P450 2D6 (CYP2D6) and is a substrate for the P-glycoprotein (P-gp) transporter. The primary metabolic routes for umeclidinium are oxidative (hydroxylation, O-dealkylation) followed by conjugation (e.g., glucuronidation), resulting in a range of metabolites with either reduced pharmacological activity or for which the pharmacological activity has not been established. Systemic exposure to the metabolites is low.

Vilanterol: In vitro data showed that vilanterol is metabolized principally by CYP3A4 and is a substrate for the P-gp transporter. Vilanterol is metabolized to a range of metabolites with significantly reduced β1- and β2-agonist activity.

Excretion: Fluticasone Furoate: The plasma elimination half-life following repeat-dose inhaled administration averaged 24 hours. Following intravenous dosing with radiolabeled fluticasone furoate, mass balance showed 90% of the radiolabel in the feces and 2% in the urine. Following oral dosing, radiolabel recovered in feces was 101% of the total dose and that in urine was approximately 1% of the total dose.

Umeclidinium: The effective half-life after once-daily oral dosing is 11 hours. Following intravenous dosing with radiolabeled umeclidinium, mass balance showed 58% of the radiolabel in the feces and 22% in the urine. The excretion of the drug-related material in the feces following intravenous dosing indicated elimination in the bile. Following oral dosing to healthy male subjects, radiolabel recovered in feces was 92% of the total dose and that in urine was <1% of the total dose, suggesting negligible oral absorption.

Vilanterol: The effective half-life for vilanterol, as determined from inhalation administration of multiple doses, is 11 hours. Following oral administration of radiolabeled vilanterol, mass balance showed 70% of the radiolabel in the urine and 30% in the feces.

Specific Populations

The effects of intrinsic and extrinsic factors on the pharmacokinetics of fluticasone furoate, umeclidinium, and vilanterol are shown in Figures 1, 2, 3, and 4. Based on population pharmacokinetic analyses in COPD and asthma, none of the covariates assessed (i.e., age, race, gender) had a clinically relevant effect on fluticasone furoate, umeclidinium, or vilanterol pharmacokinetics when administered as TRELEGY ELLIPTA.

Figure 4. Impact of Intrinsic Factors and Coadministered Drugs on the Systemic Exposure of Umeclidinium

Racial or Ethnic Groups: Fluticasone Furoate: Systemic exposure [AUC(0-24)] to inhaled fluticasone furoate was approximately 30% higher in subjects with COPD of East Asian heritage (n = 113) compared with White subjects (Figure 1). However, this higher exposure to fluticasone furoate is not expected to have clinically relevant effects on serum or urine cortisol or on efficacy in these racial groups. In East Asian subjects with asthma (Japanese, East Asian, and Southeast Asian heritage) (n = 92), there was no effect of race on pharmacokinetics of fluticasone furoate (Figure 2).

Umeclidinium: There was no effect of race on the pharmacokinetics of umeclidinium in subjects with COPD or asthma (Figures 1 and 2).

Vilanterol: There was no effect of race on the pharmacokinetics of vilanterol in subjects with COPD (Figure 1). In East Asian subjects with asthma (Japanese, East Asian, and Southeast Asian heritage) (n = 92), estimates of vilanterol Cmax at steady state were approximately 3-fold higher than non-East Asian subjects (Figure 2). However, the higher systemic exposure is not expected to have a clinically relevant effect on heart rate.

Patients with Hepatic Impairment: Fluticasone Furoate: Following repeat dosing of fluticasone furoate/vilanterol 200/25 mcg (100/12.5 mcg in the severe impairment group) for 7 days, there was an increase of 34%, 83%, and 75% in fluticasone furoate systemic exposure (AUC) in subjects with mild, moderate, and severe hepatic impairment, respectively, compared with healthy subjects (Figure 3).

In subjects with moderate hepatic impairment receiving fluticasone furoate/vilanterol 200/25 mcg, mean serum cortisol (0 to 24 hours) was reduced by 34% (90% CI: 11%, 51%) compared with healthy subjects. In subjects with severe hepatic impairment receiving fluticasone furoate/vilanterol 100/12.5 mcg, mean serum cortisol (0 to 24 hours) was increased by 14% (90% CI: -16%, 55%) compared with healthy subjects. Patients with moderate to severe hepatic disease should be closely monitored.

Umeclidinium: The impact of hepatic impairment on the pharmacokinetics of umeclidinium has been evaluated in subjects with moderate hepatic impairment (Child-Pugh score of 7-9). There was no evidence of an increase in systemic exposure to umeclidinium (Cmax and AUC) (Figure 4). There was no evidence of altered protein binding in subjects with moderate hepatic impairment compared with healthy subjects. TRELEGY ELLIPTA has not been evaluated in subjects with severe hepatic impairment.

Vilanterol: Hepatic impairment had no effect on vilanterol systemic exposure (Cmax and AUCss on Day 7) following repeat-dose administration of fluticasone furoate/vilanterol 200/25 mcg (100/12.5 mcg in the severe impairment group) for 7 days (Figure 3).

There were no additional clinically relevant effects of the fluticasone furoate/vilanterol combinations on heart rate or serum potassium in subjects with mild or moderate hepatic impairment (vilanterol 25 mcg combination) or with severe hepatic impairment (vilanterol 12.5 mcg combination) compared with healthy subjects.

Patients with Renal Impairment: Fluticasone Furoate: Systemic exposure was not increased in subjects with severe renal impairment compared with healthy subjects (Figure 3). There was no evidence of greater corticosteroid class-related systemic effects (assessed by serum cortisol) in subjects with severe renal impairment compared with healthy subjects.

Umeclidinium: The pharmacokinetics of umeclidinium has been evaluated in subjects with severe renal impairment (CrCl <30 mL/min). There was no evidence of an increase in systemic exposure to umeclidinium (Cmax and AUC) (Figure 4). There was no evidence of altered protein binding in subjects with severe renal impairment compared with healthy subjects.

Vilanterol: Systemic exposure (AUCss) was 56% higher in subjects with severe renal impairment compared with healthy subjects (Figure 3). There was no evidence of greater beta‑agonist class-related systemic effects (assessed by heart rate and serum potassium) in subjects with severe renal impairment compared with healthy subjects.

Drug Interaction Studies

No drug-drug interaction studies have been conducted with TRELEGY ELLIPTA. The information below is from drug-drug interaction studies conducted with umeclidinium, fluticasone furoate/vilanterol, or umeclidinium/vilanterol. The potential for fluticasone furoate, umeclidinium, and vilanterol to inhibit or induce metabolic enzymes and transporter systems is negligible at low inhalation doses.

Inhibitors of Cytochrome P450 3A4: The exposure (AUC) of fluticasone furoate and vilanterol were 36% and 65% higher, respectively, when coadministered with ketoconazole 400 mg compared with placebo (Figure 3). The increase in fluticasone furoate exposure was associated with a 27% reduction in weighted mean serum cortisol (0 to 24 hours). The increase in vilanterol exposure was not associated with an increase in beta-agonist–related systemic effects on heart rate or blood potassium.

Cytochrome P450 2D6: In vitro metabolism of umeclidinium is mediated primarily by CYP2D6. However, no clinically meaningful difference in systemic exposure to umeclidinium (500 mcg) (8 times the approved dose) was observed following repeat daily inhaled dosing to normal (ultra‑rapid, extensive, and intermediate metabolizers) and CYP2D6 poor metabolizer subjects.

Inhibitors of P-glycoprotein: Fluticasone furoate, umeclidinium, and vilanterol are substrates of P‑gp. Coadministration of repeat-dose (240 mg once daily) verapamil (a moderate CYP3A4 inhibitor and a P-gp inhibitor) did not affect the vilanterol Cmax or AUC in healthy subjects (Figure 3). Drug interaction trials with a specific P-gp inhibitor and fluticasone furoate have not been conducted. The effect of the moderate P-gp transporter inhibitor verapamil (240 mg once daily) on the steady-state pharmacokinetics of umeclidinium was assessed in healthy subjects. No effect on umeclidinium Cmax was observed; however, an approximately 1.4-fold increase in umeclidinium AUC was observed (Figure 4).

Carcinogenesis, Mutagenesis, Impairment of Fertility

TRELEGY ELLIPTA

No studies of carcinogenicity, mutagenicity, or impairment of fertility were conducted with TRELEGY ELLIPTA; however, studies are available for the individual components, fluticasone furoate, umeclidinium, and vilanterol, as described below.

Fluticasone Furoate

Fluticasone furoate produced no treatment-related increases in the incidence of tumors in 2-year inhalation studies in rats and mice at inhaled doses up to 9 and 19 mcg/kg/day, respectively (both approximately 0.5 times the MRHDID of 200 mcg for adults on a mcg/m2 basis).

Fluticasone furoate did not induce gene mutation in bacteria or chromosomal damage in a mammalian cell mutation test in mouse lymphoma L5178Y cells in vitro. There was also no evidence of genotoxicity in the in vivo micronucleus test in rats.

No evidence of impairment of fertility was observed in male and female rats at inhaled fluticasone furoate doses up to 29 and 91 mcg/kg/day, respectively (approximately 3 and 8 times, respectively, the MRHDID of 200 mcg for adults on an AUC basis).

Umeclidinium

Umeclidinium produced no treatment-related increases in the incidence of tumors in 2-year inhalation studies in rats and mice at inhaled doses up to 137 and 295/200 mcg/kg/day (male/female), respectively (approximately 17 and 20/20 times, respectively, the MRHDID for adults on an AUC basis).

Umeclidinium tested negative in the following genotoxicity assays: the in vitro Ames assay, in vitro mouse lymphoma assay, and in vivo rat bone marrow micronucleus assay.

No evidence of impairment of fertility was observed in male and female rats at subcutaneous doses up to 180 mcg/kg/day and at inhaled doses up to 294 mcg/kg/day, respectively (approximately 60 and 40 times, respectively, the MRHDID for adults on an AUC basis).

Vilanterol

In a 2-year carcinogenicity study in mice, vilanterol caused a statistically significant increase in ovarian tubulostromal adenomas in females at an inhaled dose of 29,500 mcg/kg/day (approximately 9,920 times the MRHDID for adults on an AUC basis). No increase in tumors was seen at an inhaled dose of 615 mcg/kg/day (approximately 370 times the MRHDID for adults on an AUC basis).

In a 2-year carcinogenicity study in rats, vilanterol caused statistically significant increases in mesovarian leiomyomas in females and shortening of the latency of pituitary tumors at inhaled doses greater than or equal to 84.4 mcg/kg/day (greater than or equal to approximately 25 times the MRHDID for adults on an AUC basis). No tumors were seen at an inhalation dose of 10.5 mcg/kg/day (approximately equal to the MRHDID for adults on an AUC basis).

These tumor 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.

Vilanterol tested negative in the following genotoxicity assays: the in vitro Ames assay, in vivo rat bone marrow micronucleus assay, in vivo rat unscheduled DNA synthesis (UDS) assay, and in vitro Syrian hamster embryo (SHE) cell assay. Vilanterol tested equivocal in the in vitro mouse lymphoma assay.

No evidence of impairment of fertility was observed in male and female rats at inhaled vilanterol doses up to 31,500 and 37,100 mcg/kg/day, respectively (both approximately 4,090 times the MRHDID based on AUC).

Chronic Obstructive Pulmonary Disease

The clinical efficacy of TRELEGY ELLIPTA has been evaluated in 3 clinical trials in subjects with COPD, including chronic bronchitis and/or emphysema: Trial 1 (NCT01957163), Trial 2 (NCT02119286), and Trial 3 (NCT02164513).

Trials 1 and 2 were multicenter, randomized, double-blind, parallel-group, 12-week treatment trials in subjects with COPD. Across both trials, a total of 412 subjects received coadministration of umeclidinium 62.5 mcg + fluticasone furoate/vilanterol 100/25 mcg, the components of TRELEGY ELLIPTA. Comparative in vitro data (drug delivery and aerodynamic particle size distribution) provide support for reliance on coadministration studies with umeclidinium 62.5 mcg + fluticasone furoate/vilanterol 100/25 mcg. These data demonstrated no pharmaceutical interactions and that each drug component (fluticasone furoate, umeclidinium, and vilanterol) was delivered in a comparable manner whether administered via a single ELLIPTA inhaler or from separate inhalers.

The population demographics for Trials 1 and 2 were: mean age of 64 years, 92% White, 66% male, and an average smoking history of 48 pack-years, with 50% identified as current smokers. At screening, the mean postbronchodilator percent predicted FEV1 was 46% (range: 14% to 76%), the mean postbronchodilator FEV1/FVC ratio was 0.48 (range: 0.21 to 0.70), and the mean percent reversibility was 13% (range: -24% to 86%).

Trial 3 was a randomized, multicenter, double-blind, parallel-group, 52-week treatment trial comparing the clinical efficacy of TRELEGY ELLIPTA 100/62.5/25 mcg with the fixed-dose combinations of fluticasone furoate/vilanterol 100/25 mcg and umeclidinium/vilanterol 62.5/25 mcg. A total of 10,355 subjects with COPD with a history of 1 or more moderate or severe exacerbations in the prior 12 months were randomized (2:2:1) to receive TRELEGY ELLIPTA, fluticasone furoate/vilanterol, or umeclidinium/vilanterol administered once daily.

The population demographics across all treatments were: mean age of 65 years, 77% White, 66% male, and an average smoking history of 46.6 pack-years, with 35% identified as current smokers. At study entry, the most common COPD medications were ICS + anticholinergic + LABA (34%), ICS + LABA (26%), anticholinergic + LABA (8%), and anticholinergic (7%); the mean postbronchodilator percent predicted FEV1 was 46% (SD: 15%), the mean postbronchodilator FEV1/FVC ratio was 0.47 (SD: 0.12), and the mean percent reversibility was 10% (range: -59% to 125%).

Lung Function: In Trials 1 and 2, the primary endpoint was change from baseline in trough (predose) FEV1 at Day 85 (defined as the mean of the FEV1 values obtained at 23 and 24 hours after the previous dose on Day 84). For both COPD trials, umeclidinium + fluticasone furoate/vilanterol demonstrated a statistically significant increase relative to placebo + fluticasone furoate/vilanterol (Table 4); similar results were demonstrated for the secondary endpoint of the weighted mean FEV1 (0 to 6 hours postdose) on Day 84 .

Greater least squares (LS) mean changes from baseline in FEV1 over time were demonstrated for the umeclidinium + fluticasone furoate/vilanterol treatment group compared with the placebo + fluticasone furoate/vilanterol treatment group starting at 15 minutes postdose on Day 1. For Trial 1, LS mean changes in FEV1 over time relative to baseline are displayed for Day 1 and Day 84 in Figures 5 and 6, respectively. Similar results were seen in Trial 2.

Figure 6. Least Squares (LS) Mean Change from Baseline in Postdose Serial FEV1 (mL) on Day 84

In Trial 3, treatment with TRELEGY ELLIPTA 100/62.5/25 mcg demonstrated a statistically significant improvement in lung function (mean change from baseline trough FEV1 at Week 52) compared with fluticasone furoate/vilanterol and umeclidinium/vilanterol. The mean change from baseline in trough (predose) FEV1 at Week 52 was 97 mL for TRELEGY ELLIPTA compared with fluticasone furoate/vilanterol (95% CI: 85, 109; P<0.001) and 54 mL for TRELEGY ELLIPTA compared with umeclidinium/vilanterol (95% CI: 39, 69; P<0.001). The effects on lung function (mean change from baseline trough FEV1) of TRELEGY ELLIPTA compared with fluticasone furoate/vilanterol and umeclidinium/vilanterol were observed at all timepoints over the course of the 52-week study (Figure 7).

Exacerbations: In Trial 3, the primary endpoint was annual rate of on-treatment moderate and severe exacerbations in subjects with COPD treated with TRELEGY ELLIPTA 100/62.5/25 mcg compared with fluticasone furoate/vilanterol and umeclidinium/vilanterol. Exacerbations were defined as worsening of 2 or more major symptoms (dyspnea, sputum volume, and sputum purulence) or worsening of any 1 major symptom together with any 1 of the following minor symptoms: sore throat, colds (nasal discharge and/or nasal congestion), fever without other cause, and increased cough or wheeze for at least 2 consecutive days. Exacerbations were considered to be moderate severity if treatment with systemic corticosteroids and/or antibiotics was required and were considered to be severe if resulted in hospitalization or death.

Treatment with TRELEGY ELLIPTA statistically significantly reduced the on-treatment annual rate of moderate/severe exacerbations by 15% compared with fluticasone furoate/vilanterol and by 25% compared with umeclidinium/vilanterol .

Treatment with TRELEGY ELLIPTA statistically significantly decreased the risk of a moderate/severe COPD exacerbation as measured by time to first exacerbation when compared with fluticasone furoate/vilanterol (14.8%; 95% CI: 9.3, 19.9; P<0.001) and umeclidinium/vilanterol (16.0%; 95% CI: 9.4, 22.1; P<0.001).

Treatment with TRELEGY ELLIPTA reduced the on-treatment annual rate of severe COPD exacerbations (i.e., requiring hospitalization or resulting in death) by 13% compared with fluticasone furoate/vilanterol (95% CI: -1, 24; P = 0.064) which was not statistically significant. Treatment with TRELEGY ELLIPTA statistically significantly reduced the on-treatment annual rate of severe COPD exacerbations by 34% compared with umeclidinium/vilanterol (95% CI: 22, 44; P<0.001).

Health-Related Quality of Life: In all 3 trials, health-related quality of life was assessed using the St. George’s Respiratory Questionnaire for COPD patients (SGRQ-C), a disease-specific shorter version derived from the original St. George’s Respiratory Questionnaire (SGRQ). Results were transformed to the SGRQ for reporting purposes. In Trial 1, the on-treatment responder rate at Week 12 (response defined as a decrease in score from baseline of 4 or more) was 40% for umeclidinium +fluticasone furoate/vilanterol vs. 35% for placebo + fluticasone furoate/vilanterol [odds ratio (OR): 1.2; 95% CI: 0.8, 1.8]. In Trial 2, the on-treatment responder rate at Week 12 was 35% for umeclidinium + fluticasone furoate/vilanterol vs. 21% for placebo + fluticasone furoate/vilanterol (OR: 2.0; 95% CI: 1.3, 3.1). In Trial 3, the on-treatment responder rate at Week 52 was statistically significantly greater for subjects treated with TRELEGY ELLIPTA (42%) compared with fluticasone furoate/vilanterol (34%; OR: 1.41; 95% CI: 1.29, 1.55; P<0.001) and compared with umeclidinium/vilanterol (34%; OR: 1.41; 95% CI: 1.26, 1.57; P<0.001).

Other Endpoints: In Trials 1 and 2, subjects treated with umeclidinium + fluticasone furoate/vilanterol on average used less rescue medication compared with subjects treated with placebo + fluticasone furoate/vilanterol over Weeks 1 to 12. In Trial 3, subjects treated with TRELEGY ELLIPTA on average used less rescue medication (mean number of uses per day and percentage of rescue-free 24-hour periods) compared with subjects treated with fluticasone furoate/vilanterol or umeclidinium/vilanterol over the course of the 52-week study.

Asthma

The safety and efficacy of TRELEGY ELLIPTA were evaluated in 2,436 subjects in a randomized, double-blind, parallel-group, active-controlled confirmatory trial of 24 to 52 weeks’ duration in adult subjects with asthma inadequately controlled on their current treatments of combination therapy (ICS plus a LABA) (Trial 4, NCT02924688).

Subjects with an Asthma Control Questionnaire (ACQ-6) score ≥1.5 on their current asthma treatment of ICS (greater than fluticasone propionate 250 mcg/day or equivalent) plus LABA entered a 3-week run-in period of treatment with fluticasone propionate/salmeterol 250/50 mcg twice daily. Subjects who remained inadequately controlled (ACQ-6 ≥1.5) after the run-in period were transferred to fluticasone furoate/vilanterol 100/25 mcg once daily for a 2-week stabilization period. After the 5-week run-in/stabilization period, eligible subjects were randomized to receive once-daily inhalations of TRELEGY ELLIPTA 100/62.5/25 mcg (n = 406), TRELEGY ELLIPTA 200/62.5/25 mcg (n = 408), fluticasone furoate/umeclidinium/vilanterol 100/31.25 mcg/25 mcg (n = 405), fluticasone furoate/umeclidinium/vilanterol 200/31.25 mcg/25 mcg (n = 404), fluticasone furoate/vilanterol 100/25 mcg (n = 407), or fluticasone furoate/vilanterol 200/25 mcg (n = 406).

Across all treatment groups, baseline demographics were similar. The majority of subjects were female (62%), White (80%), and had never smoked (81%), with a mean age of 53 years and mean asthma duration of 21 years (range: 1 to 70). The trial excluded current smokers; past smokers had an average smoking history of 4.3 pack-years. In the prior 12 months, 85% of subjects reported having any exacerbation; approximately 63% of subjects reported having an exacerbation that required oral/systemic corticosteroids and/or hospitalization.

At screening, the mean prebronchodilator percent predicted FEV1 was 58.5% (SD: 12.8%); the mean percent reversibility was 29.9% (SD: 18.1%), with a mean absolute reversibility of 484 mL (SD: 274 mL), and the mean ACQ-6 score was 2.5 (SD: 0.6). During the 5-week run‑in/stabilization period, subjects had improvements in both lung function (trough FEV1 improvement of 287 mL) and asthma control (mean ACQ-6 score decreased by 0.6). At randomization, the majority (93%) remained not well controlled (mean ACQ-6 score of 1.9) and the mean prebronchodilator percent predicted FEV1 was 68.2% (SD: 14.8%).

Lung Function: The primary efficacy endpoint was change from baseline in trough FEV1 at Week 24. Both TRELEGY ELLIPTA 100/62.5/25 mcg and TRELEGY ELLIPTA 200/62.5/25 mcg showed statistically significant improvements in lung function compared with fluticasone furoate/vilanterol 100/25 mcg and fluticasone furoate/vilanterol 200/25 mcg, respectively ( Table 6, Figures 8 and 9).

Figure 9. Least Squares Mean Change from Baseline in Trough FEV1 (mL) with TRELEGY ELLIPTA 200/62.5/25 mcg over 24 Weeks of Treatment

The difference in change from baseline in trough FEV1 at Week 24 for TRELEGY ELLIPTA 100/62.5/25 mcg compared with fluticasone furoate/vilanterol 200/25 mcg was 59 mL (95% CI: 15, 102).

The change from baseline in FEV1 at 3 hours post-dose was supportive of the primary endpoint with improvements for TRELEGY ELLIPTA 100/62.5/25 mcg compared with fluticasone furoate/vilanterol 100/25 mcg (111 mL, 95% CI: 67, 155) and TRELEGY ELLIPTA 200/62.5/25 mcg compared with fluticasone furoate/vilanterol 200/25 mcg (118 mL, 95% CI: 74, 162).

Onset of action was determined in a separate trial conducted with fluticasone furoate/vilanterol; the median time to onset (defined as a 100-mL increase from baseline in mean FEV1) was approximately 15 minutes.

Additional bronchodilator effects of umeclidinium in TRELEGY ELLIPTA compared with fluticasone furoate/vilanterol were present over the 24-hour dosing period as shown by 3 hours post-dose FEV1, PM FEV1, and trough FEV1 endpoints. The bronchodilator effects of TRELEGY ELLIPTA were consistently observed from Week 1 through Week 24.

Exacerbations: Asthma exacerbations were assessed over the 52-week treatment period. Asthma exacerbations were defined as deterioration of asthma requiring the use of systemic corticosteroid (or at least a doubling of maintenance dose) for at least 3 days or an inpatient hospitalization or emergency department visit due to asthma that required systemic corticosteroid.

In a descriptive pooled analysis, the mean annualized rate of exacerbations was 0.31 for TRELEGY ELLIPTA [100/62.5/25 and 200/62.5/25 mcg, 127 of 814 (16%) patients reported exacerbations] and 0.31 for fluticasone furoate/vilanterol [100/25 and 200/25 mcg, 132 of 813 (16%) patients reported exacerbations] (2.6% reduction in rate; 95% CI: -26.2, 24.9).

In descriptive unpooled analyses, the mean annualized rates of exacerbations were 0.41 and 0.23 for TRELEGY ELLIPTA 100/62.5/25 mcg and TRELEGY ELLIPTA 200/62.5/25 mcg, respectively. The mean annualized rates of exacerbations were 0.38 and 0.26 for fluticasone furoate/vilanterol 100/25 mcg and fluticasone furoate/vilanterol 200/25 mcg, respectively.

Health-Related Quality of Life: Additional efficacy measures included Asthma Control Questionnaire (ACQ). The ACQ-7 incorporates 5 questions on symptoms, FEV1, and rescue bronchodilator use and was assessed at Week 24. ACQ-7 (7-items) responder was defined as a decrease in score of ≥0.5.

In a descriptive pooled analysis, the ACQ-7 responder rate was 63% for TRELEGY ELLIPTA (100/62.5/25 and 200/62.5/25 mcg) compared with 55% for fluticasone furoate/vilanterol (100/25 and 200/25 mcg) at Week 24, favoring TRELEGY ELLIPTA (OR: 1.43; 95% CI: 1.16, 1.76).

In an unpooled descriptive analysis, the ACQ-7 responder rate was 62% for TRELEGY ELLIPTA 100/62.5/25 mcg compared with 52% for fluticasone furoate/vilanterol 100/25 mcg (OR: 1.59; 95% CI: 1.18, 2.13) at Week 24, favoring TRELEGY ELLIPTA. The ACQ-7 responder rate was 64% for TRELEGY ELLIPTA 200/62.5/25 mcg compared with 58% for fluticasone furoate/vilanterol 200/25 mcg (OR: 1.28; 95% CI: 0.95, 1.72) at Week 24, favoring TRELEGY ELLIPTA.

The ACQ-5 (comprising the 5 questions on symptoms from ACQ-7) responder rates at Week 24 for pooled and unpooled analyses were similar to the ACQ-7 results.
