ALVESCO

The active component of ALVESCO 80 mcg, and ALVESCO 160 mcg is ciclesonide, a non-halogenated glucocorticoid having the chemical name pregna-1,4-diene-3,20-dione, 16,17-[[(R)-cyclohexylmethylene]bis(oxy)]-11-hydroxy-21-(2-methyl-1-oxopropoxy)-,(11β,16α). The empirical formula is C 32 H 44 O 7 and its molecular weight is 540.7. Its structural formula is as follows: Ciclesonide is a white to yellow-white powder. It is soluble in dehydrated alcohol, acetone, dichloromethane, and chloroform. ALVESCO 80 mcg and ALVESCO 160 mcg are pressurized, metered-dose aerosol units fitted with a dose indicator. ALVESCO is intended for oral inhalation only. Each unit contains a solution of ciclesonide in propellant HFA-134a (1,1,1,2 tetrafluoroethane) and ethanol. After priming, ALVESCO 80 mcg delivers 100 mcg from the valve and 80 mcg of ciclesonide from the actuator. ALVESCO 160 mcg delivers 200 mcg from the valve and 160 mcg of ciclesonide from the actuator. This product delivers 50 microliters (59.3 milligrams) of solution as a fine particle mist from the valve with each actuation. The actual amount of drug delivered to the lung may depend on patient factors, such as the coordination between the actuation of the device and inspiration through the delivery system. ALVESCO should be “primed” by actuating 3 times prior to using the first dose from a new canister or when the inhaler has not been used for more than 10 days. Avoid spraying in the eyes or face while priming ALVESCO. Structural Formula

For oral inhalation only. ( 2 ) Prime ALVESCO before first use or when inhaler not used for more than 10 days. ( 2 ) 1 Prednisone should be reduced gradually, no faster than 2.5 mg/day on a weekly basis, beginning after at least 1 week of therapy with ALVESCO. Patients should be carefully monitored for signs of asthma instability, including monitoring of serial objective measures of airflow, and for signs of adrenal insufficiency during steroid taper and following discontinuation of oral corticosteroid therapy [see Warnings and Precautions ( 5.1 )] . Previous Therapy Recommended Starting Dose Highest Recommended Dose Patients ≥ 12 years who received bronchodilators alone 80 mcg twice daily 160 mcg twice daily Patients ≥ 12 years who received inhaled corticosteroids 80 mcg twice daily 320 mcg twice daily Patients ≥ 12 years who received oral corticosteroids 1 320 mcg twice daily 320 mcg twice daily 2.1 Administration Information Administer ALVESCO by the orally inhaled route. After administration, rinse the mouth with water and spit out without swallowing to help reduce the risk of oropharyngeal candidiasis [see Warnings and Precautions ( 5.1 )] . Priming Prime ALVESCO before using for the first time by actuating 3 times prior to using the first dose from a new canister or when the inhaler has not been used for more than 10 days. 2.2 Recommended Dosage The recommended starting dosage and the highest recommended dosage of ALVESCO are listed in Table 1 Table 1: Recommended Dosages for Adults and Pediatric Patients 12 Years and Older 1 Prednisone should be reduced gradually, no faster than 2.5 mg/day on a weekly basis, beginning after at least 1 week of therapy with ALVESCO. Patients should be carefully monitored for signs of asthma instability, including monitoring of serial objective measures of airflow, and for signs of adrenal insufficiency during steroid taper and following discontinuation of oral corticosteroid therapy [see Warnings and Precautions ( 5.1 )] . Previous Therapy Recommended Starting Dosage Highest Recommended Dosage Patients ≥ 12 years who received bronchodilators alone 80 mcg twice daily 160 mcg twice daily Patients ≥ 12 years who received inhaled corticosteroids 80 mcg twice daily 320 mcg twice daily Patients ≥ 12 years who received oral corticosteroids 1 320 mcg twice daily 320 mcg twice daily General Dosing Recommendations Individual patients will experience a variable time to onset and degree of symptom relief. Maximum benefit may not be achieved for four weeks or longer after initiation. After asthma stability has been achieved, it is desirable to titrate to the lowest effective dosage to reduce the possibility of side effects. For patients who do not respond adequately to the starting dose after 4 weeks of therapy, higher doses may provide additional asthma control. Patients should not exceed the highest recommended dosage per day.

ALVESCO is contraindicated in: the primary treatment of status asthmaticus or other acute episodes of asthma where intensive measures are required. patients with known hypersensitivity to ciclesonide or any of the ingredients of ALVESCO. Rare cases of hypersensitivity reactions with manifestations such as angioedema, with swelling of the lips, tongue and pharynx, have been reported. Patients with status asthmaticus or other acute episodes of asthma where intensive measures are required.

Studies with once daily dosing are omitted from the safety database because the doses studied once daily are lower than the highest recommended twice daily doses. The five studies were of 12 to 16 weeks treatment duration, one of which included a safety extension follow-up of one year. In the 12 to 16 week treatment studies, 720 patients (298 males and 422 females) aged 12 years and older were exposed to ALVESCO. In the long-term safety trial, 197 patients (82 males and 115 females) with severe persistent asthma from one of the 12-week trials were re-randomized and treated for up to one year with ALVESCO 320 mcg twice daily. Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Adults and Pediatric Patients 12 Years of Age and Older Four of the five trials included a total of 624 patients ages 12 years and older (359 females and 265 males) with asthma of varying severity who were treated with ALVESCO 80 mcg, 160 mcg, or 320 mcg twice daily for 12 to 16 weeks. These studies included patients previously using either controller therapy (predominantly inhaled corticosteroids) or reliever therapy (bronchodilator therapy alone). In these trials, the mean age was 39.1 years, and the majority of the patients (79.0%) were Caucasian. In these trials, 52.3%, 59.8% and 54.1% of the patients in the ALVESCO 80 mcg, 160 mcg, and 320 mcg treatment groups, respectively, had at least one adverse event compared to 58.0% in the placebo group. Table 2 includes adverse reactions for the recommended doses of ALVESCO that occurred at an incidence of ≥ 3% in any of the ALVESCO groups and which were more frequent with ALVESCO compared to placebo.

Infections and Infestations : Oral candidiasis Respiratory Disorders : Cough Gastrointestinal Disorders : Dry mouth, nausea General Disorders and Administrative Site Conditions : Chest discomfort Respiratory, Thoracic, and Mediastinal Disorders : Dysphonia, dry throat The fifth study was a 12-week clinical trial in asthma patients 12 years of age and older who previously required oral corticosteroids (average daily dose of oral prednisone of 12 mg/day), in which the effects of ALVESCO 320 mcg twice daily (n = 47) and 640 mcg twice daily (n = 49) were compared with placebo (n = 45) for the frequency of reported adverse reactions. The following adverse reactions occurred at an incidence of ≥ 3% in the ALVESCO-treated patients and were more frequent compared to placebo: sinusitis, hoarseness, oral candidiasis, influenza, pneumonia, nasopharyngitis, arthralgia, back pain, musculoskeletal chest pain, headache, urticaria, dizziness, gastroenteritis, face edema, fatigue, and conjunctivitis. Long-Term Clinical Trials Experience A total of 197 patients 12 years of age and older (82 males and 115 females) from one of the 12-week treatment placebo-controlled studies were re-randomized to ciclesonide 320 mcg twice daily and followed for one year. The safety profile from the one-year follow-up was similar to that seen in the 12- and 16-week treatment studies. 6.2 Post-marketing Experience In addition to adverse reactions identified from clinical trials, the following adverse reactions have been identified during worldwide post-marketing use of ciclesonide oral inhalation. 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. Immune System Disorders : Immediate or delayed hypersensitivity reactions such as angioedema with swelling of the lips, tongue and pharynx.

In clinical studies, concurrent administration of ciclesonide and other drugs commonly used in the treatment of asthma (albuterol, formoterol) had no effect on pharmacokinetics of des-ciclesonide [see Clinical Pharmacology ( 12.3 )] . In vitro studies and clinical pharmacology studies suggested that des-ciclesonide has no potential for metabolic drug interactions or protein binding-based drug interactions [see Clinical Pharmacology ( 12.3 )] . In a drug interaction study, co-administration of orally inhaled ciclesonide and oral ketoconazole, a potent inhibitor of cytochrome P450 3A4, increased the exposure (AUC) of des-ciclesonide by approximately 3.6-fold at steady state, while levels of ciclesonide remained unchanged.
