FDA Approves AirDuo RespiClick
Teva Announces FDA Approval of AirDuo RespiClick (fluticasone propionate and salmeterol) for Maintenance Treatment of Asthma
JERUSALEM--(BUSINESS WIRE) January 30, 2017 --Teva Pharmaceutical Industries Ltd., (NYSE and TASE: TEVA) today announced that the U.S. Food and Drug Administration (FDA) has approved AirDuo RespiClick (fluticasone propionate and salmeterol inhalation powder) for adolescent and adult patients with asthma. The medication is delivered via Teva’s RespiClick® breath-activated, multi-dose dry powder inhaler (MDPI) which is used with other approved medicines in Teva’s respiratory product portfolio.
AirDuo RespiClick is a fixed dose combination product containing the same active ingredients as Advair. AirDuo RespiClick is a corticosteroid and a long-acting beta2-adrenergic agonist (LABA) indicated for the treatment of asthma in patients aged 12 years and older.
AirDuo RespiClick is expected to become available to patients in the U.S., by prescription, later this year. The product has been approved in three strengths. The approved strengths of AirDuo RespiClick are: 55/14 mcg, 113/14 mcg and 232/14 mcg administered as one inhalation twice daily.
The FDA’s approval of AirDuo RespiClick is supported by data from Teva’s clinical development program, including three Phase III trials which evaluated the efficacy and safety of the treatment in adolescent and adult patients with asthma. In the two double-blind studies, the therapy showed clinically relevant and greater benefit compared with placebo in the improvement of lung function after 12 weeks of treatment as measured by Forced Expiratory Volume in one second (FEV1). In clinical trials for AirDuo RespiClick, the most common adverse reactions (incidence ≥3%) were nasopharyngitis, headache, cough, oral candidiasis and back pain.
About AirDuo RespiClick (Fluticasone Propionate and Salmeterol) Inhalation Powder
AirDuo RespiClick is indicated for the treatment of asthma in patients aged 12 years and older. AirDuo RespiClick is only for patients uncontrolled on an ICS or whose disease severity clearly warrants an ICS/LABA.
Important Limitation of Use: AirDuo RespiClick is NOT indicated for the relief of acute bronchospasm.
IMPORTANT SAFETY INFORMATION
WARNING: ASTHMA-RELATED DEATH
- Long-acting beta2-adrenergic agonists (LABA), such as salmeterol, one of the active ingredients in AirDuo RespiClick, increase the risk of asthma-related death. Data from a large placebo-controlled US trial that compared the safety of salmeterol with placebo added to usual asthma therapy showed an increase in asthma-related deaths in subjects receiving salmeterol (13 deaths out of 13,176 subjects treated for 28 weeks on salmeterol versus 3 deaths out of 13,179 subjects on placebo). Currently available data are inadequate to determine whether concurrent use of inhaled corticosteroids or other long-term asthma control drugs mitigates the increased risk of asthma-related death from LABA. Available data from controlled clinical trials suggest that LABA increase the risk of asthma-related hospitalization in pediatric and adolescent patients
- Therefore, when treating patients with asthma, physicians should only prescribe AirDuo RespiClick for patients not adequately controlled on a long-term asthma control medication, such as an inhaled corticosteroid, or whose disease severity clearly warrants initiation of treatment with both an inhaled corticosteroid and a LABA. Once asthma control is achieved and maintained, assess the patient at regular intervals and step down therapy (e.g., discontinue AirDuo RespiClick) if possible without loss of asthma control and maintain the patient on a long-term asthma control medication, such as an inhaled corticosteroid. Do not use AirDuo RespiClick for patients whose asthma is adequately controlled on low- or medium-dose inhaled corticosteroids
- Contraindications: AirDuo RespiClick is contraindicated in
- Primary treatment of status asthmaticus or other acute episodes of asthma where intensive measures are required
- Patients with known severe hypersensitivity to milk proteins or known hypersensitivity to fluticasone propionate or any of the excipients
- Deterioration of Disease and Acute Episodes: Serious acute respiratory events, including fatalities, have been reported when salmeterol, a component of AirDuo RespiClick, has been initiated in patients with significantly worsening or acutely deteriorating asthma. AirDuo RespiClick should not be initiated in patients during rapidly deteriorating or potentially life-threatening episodes of asthma. AirDuo RespiClick is not indicated for the relief of acute bronchospasm. An inhaled, short-acting beta2-agonist, not AirDuo RespiClick, should be used to relieve acute symptoms such as shortness of breath
- Excessive Use and Use with Other Long acting Beta2-Agonists: AirDuo RespiClick should not be used more often than recommended, at higher doses than recommended, or in conjunction with other medicines 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 AirDuo RespiClick should not use another medicine containing a LABA (e.g., salmeterol, formoterol fumarate, arformoterol tartrate, indacaterol) for any reason
- Local Effects of Inhaled Corticosteroids: Oropharyngeal candidiasis has occurred in patients treated with AirDuo RespiClick. Advise patients to rinse the mouth with water without swallowing following inhalation
- Immunosuppression: Patients who use corticosteroids are at risk for potential worsening of existing tuberculosis; fungal, bacterial, viral, or parasitic infections; or ocular herpes simplex. A more serious or even fatal course of chickenpox or measles may occur in susceptible patients. Use with caution, if at all, in patients with the above because of the potential for worsening of these infections
- Transferring Patients from Systemic Corticosteroid Therapy: Particular care is needed for patients who have been transferred from systemically active corticosteroids to inhaled corticosteroids because deaths due to adrenal insufficiency have occurred in patients with asthma during and after transfer from systemic corticosteroids to less systemically available inhaled corticosteroids. Taper patients slowly from systemic corticosteroids if transferring to AirDuo RespiClick
- Hypercorticism and Adrenal Suppression: Because of the possibility of significant systemic absorption of inhaled corticosteroids, patients treated with AirDuo RespiClick should be observed carefully for any evidence of systemic corticosteroid effects. If such effects occur, the dosage of AirDuo RespiClick should be reduced slowly, consistent with accepted procedures for reducing systemic corticosteroids, and for management of asthma symptoms Drug Interactions with Strong Cytochrome P450 3A4 Inhibitors: The use of strong cytochrome P450 3A4 (CYP3A4) inhibitors (e.g., ritonavir, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, saquinavir, ketoconazole, telithromycin) with AirDuo RespiClick is not recommended because increased systemic corticosteroid and increased cardiovascular adverse effects may occur
- Paradoxical Bronchospasm and Upper Airway Symptoms: AirDuo RespiClick can produce paradoxical bronchospasm, which may be life-threatening. If paradoxical bronchospasm occurs following dosing with inhaled fluticasone propionate/salmeterol medicines, it should be treated immediately with an inhaled, short-acting bronchodilator; inhaled fluticasone propionate/salmeterol medicines should be discontinued immediately; and alternative therapy should be instituted. Upper airway symptoms of laryngeal spasm, irritation, or swelling, such as stridor and choking, have been reported
- Hypersensitivity Reactions, Including Anaphylaxis: Immediate hypersensitivity reactions (e.g., urticaria, angioedema, rash, bronchospasm, hypotension), including anaphylaxis, may occur after administration of AirDuo RespiClick. Discontinue AirDuo RespiClick if such reactions occur Cardiovascular and Central Nervous System Effects: AirDuo RespiClick should be used with caution in patients with cardiovascular disorders, especially coronary insufficiency, cardiac arrhythmias, and hypertension. Salmeterol, a component of AirDuo RespiClick, can produce clinically significant cardiovascular effects in some patients as measured by pulse rate, blood pressure, and/or symptoms. If such effects occur, AirDuo RespiClick may need to be discontinued
- Reduction in Bone Mineral Density (BMD): Decreases in BMD have been observed with long-term administration of products containing inhaled corticosteroids. Patients with major risk factors for decreased bone mineral content, such as prolonged immobilization, family history of osteoporosis, 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 Effect on Growth: Inhaled corticosteroids, including AirDuo RespiClick, may cause a reduction in growth velocity when administered to pediatric patients. Monitor the growth of pediatric patients receiving AirDuo RespiClick routinely (e.g., via stadiometry). Titrate each patient’s dosage to the lowest dosage that effectively controls his/her symptoms
- Glaucoma and Cataracts: Glaucoma, increased intraocular pressure, and cataracts have been reported in patients with asthma following the long-term administration of inhaled corticosteroids, including fluticasone propionate. Therefore, close monitoring is warranted in patients with a change in vision or with a history of increased intraocular pressure, glaucoma, and/or cataracts
- Eosinophilic Conditions and Churg-Strauss Syndrome: Systemic eosinophilic conditions, such as Churg-Strauss syndrome, may occur. These events usually, but not always, have been associated with the reduction and/or withdrawal of oral corticosteroid therapy following the introduction of fluticasone propionate. Be alert to eosinophilia, vasculitic rash, worsening pulmonary symptoms, cardiac complications, and/or neuropathy
- Coexisting Conditions: Use with caution in patients with convulsive disorders, thyrotoxicosis, diabetes mellitus, ketoacidosis, and in patients who are unusually responsive to sympathomimetic amines
- Hypokalemia and Hyperglycemia: Be alert to hypokalemia and hyperglycemia Adverse Reactions: Most common adverse reactions (≥3%) in patients taking AirDuo RespiClick 55/14 mcg twice daily, 113/14 mcg twice daily, 232/14 mcg twice daily, and placebo, respectively, were nasopharyngitis (8.6%, 4.8%, 6.9%, 4.4%), oral candidiasis (1.6%, 2.2%, 3.4%, 0.7%), back pain (3.1%, 0.7%, 0%, 1.8%), headache (5.5%, 4.8%, 2.8%, 4.4%), and cough (2.3%, 3.7%, 0.7%, 2.6%)
- Drug Interactions:
- Inhibitors of Cytochrome P450 3A4: The use of strong CYP3A4 inhibitors (e.g., ritonavir, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, saquinavir, ketoconazole, telithromycin) with AirDuo RespiClick is not recommended because increased systemic corticosteroid and increased cardiovascular adverse effects may occur
- Monoamine Oxidase Inhibitors and Tricyclic Antidepressants: AirDuo RespiClick should be administered with extreme caution to patients being treated with monoamine oxidase inhibitors or tricyclic antidepressants, or within 2 weeks of discontinuation of such agents, because the action of salmeterol, a component of AirDuo RespiClick, on the vascular system may be potentiated by these agents
- Beta-Adrenergic Receptor Blocking Agents: Beta-blockers not only block the pulmonary effect of beta-agonists, such as salmeterol, a component of AirDuo RespiClick, but may also produce severe bronchospasm in patients with asthma. Therefore, patients with asthma should not normally be treated with beta-blockers
- Non-Potassium-Sparing Diuretics: The ECG changes and/or hypokalemia that may result from the administration of non–potassium-sparing diuretics (such as loop or thiazide diuretics) can be acutely worsened by beta-agonists, such as salmeterol, a component of AirDuo RespiClick. Caution is advised in the coadministration of AirDuo RespiClick with non–potassium-sparing diuretics
- Use in Specific Populations: Since both fluticasone propionate and salmeterol are predominantly cleared by hepatic metabolism, impairment of liver function may lead to accumulation of fluticasone propionate and salmeterol in plasma. Therefore, patients with hepatic disease should be closely monitored
Asthma is a chronic (long term) disease usually characterized by airway inflammation and narrowing of the airways, which can vary over time. Asthma may cause recurring periods of wheezing (a whistling sound when you breathe), chest tightness, shortness of breath and coughing that often occurs at night or early in the morning. Without appropriate treatment, asthma symptoms may become more severe and result in an asthma attack, which can lead to hospitalization and even death.
