Detailed description: Asthma is a chronic disease that is estimated to affect over 25 million people both in the U. S. and in Europe (i. e. approximately 10% of the total population). Pharmacological therapy is used to treat reversible airway obstruction, inflammation and hyper-reactivity. Medications include preventive treatments in forms of antinflammatory/antiallergic agents (i. e. glucocorticosteroids, leukotriene antagonists, cromolyn sodium) and reliever treatments, in forms of bronchodilators (i. e. β-adrenergic agonists, anticholinergics). In patients treated with inhaled glucocorticosteroids whose asthma is not fully controlled, national and international guidelines recommend a stepwise approach. Recent evidence-based clinical trials show that the addition of a LABA to inhaled glucocorticosteroids is more beneficial in terms of asthma control than increasing the dose of corticosteroids alone. COMPARISONS: CHF 1535 (BECLOMETHASONE DIPROPIONATE 100 µg+ FORMOTEROL 6 µg) pMDI via HFA-134a compared to SYMBICORT (BUDESONIDE 160 µg + FORMOTEROL 4,5 µg).

Eligibility

Minimum age: 18 Years. Maximum age: 65 Years. Gender(s): Both.

Criteria:

Inclusion Criteria:

- Clinical diagnosis of moderate to severe persistent asthma for at least 6 months,

according to GINA revised version 2002 guidelines:

- Forced expiratory volume (FEV1) or peak expiratory flow rate (PEFR) > 50% and <

80% of the predicted normal;

- Asthma not adequately controlled with the current therapies, defined as presence

of daily asthma symptoms > once a week and night-time asthma symptoms > twice a month, and daily use of short-acting β2-agonists. These findings are to be based on recent medical history and are to be confirmed in the 2-week run-in period.

- Treatment with inhaled corticosteroids at a daily dose ≤ 1000 μg of BDP or

equivalent. The daily dose of inhaled corticosteroids taken at visit 1 will be assessed taking into account the following ratios between the doses of the different steroids: fluticasone propionate : BDP CFC = 1 : 2; budesonide : BDP CFC = 4 : 5; flunisolide : BDP CFC = 1 : 1. The ratios between inhaled steroids are irrespective of the formulations (i. e. spray aerosol or powder) used. When BDP is given in the new extra-fine HFA-134a formulation (as QVAR®, 3M Healthcare), the ratio with BDP CFC is set as 2 : 5. Therefore, the maximum allowed daily dose of inhaled corticosteroids at study entry will be: budesonide 800 μg, fluticasone propionate 500 μg, flunisolide 1000 μg, BDP 1000 mcg, BDP HFA extra-fine 400 μg.

- Positive response to the reversibility test in the screening visit, defined

as an increase of at least 12% (or, alternatively, of 200mL) from baseline value in the measurement of FEV1 30 minutes following 2 puffs (2 x 100 µg) of inhaled salbutamol administered via pMDI. The reversibility test can be avoided in patients having a documented positive response in the previous 6 months.

- A co-operative attitude and ability to be trained to correctly use the

metered dose inhalers and to complete the diary cards.

- Written informed consent obtained.

- At the end of the 2-week run-in period, the presence of daily asthma

symptoms (of at least mild intensity) and nighttime asthma symptom (of at least mild intensity) > once a week, as well as of daily use of relief salbutamol is to be confirmed by reviewing the diary cards for run-in Exclusion Criteria:

- Inability to carry out pulmonary function testing;

- Diagnosis of Chronic Obstructive Pulmonary Disease (COPD) as defined by the

National Heart Lung and Blood Institute/World Health Organisation (NHLBI/WHO) Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines (30);

- History of near fatal asthma;

- Evidence of severe asthma exacerbation or symptomatic infection of the airways

in the previous 8 weeks;

- Three or more courses of oral corticosteroids or hospitalisation due to asthma

during the previous 6 months;

- Patients treated with long-acting β2-agonists, anticholinergics and

antihistamines during the previous 2 weeks, with topical or intranasal corticosteroids and leukotriene antagonists during the previous 4 weeks;

- Patients who have changed their dose of inhaled corticosteroids during the

previous 4 weeks, or treatment with inhaled corticosteroids at a daily dose > 1000 μg of BDP or equivalent (except for extra-fine formulations, see inclusion criteria);

- Current smokers or recent (less than one year) ex-smokers, defined as smoking at

least 10 cigarettes/day;

- History or current evidence of heart failure, coronary artery disease,

myocardial infarction, severe hypertension, cardiac arrhythmias;

- Diabetes mellitus;

- Percutaneous transluminal coronary angioplasty (PTCA) or coronary artery by-pass

graft (CABG) during the previous six months;

- Patients with an abnormal QTc interval value in the ECG test, defined as > 450

msec in males or > 470 msec in females;

- Other haemodynamic relevant rhythm disturbances (including atrial flutter or

atrial fibrillation with ventricular response, bradycardia (≤ 55 bpm), evidence of atrial-ventricular (AV) block on ECG of more than 1st degree;

- Clinically significant or unstable concurrent diseases: uncontrolled

hyperthyroidism, significant hepatic impairment, poorly controlled pulmonary (tuberculosis, active mycotic infection of the lung), gastrointestinal (e. g. active peptic ulcer), neurological or haematological autoimmune diseases;

- Cancer or any chronic diseases with prognosis < 2 years;

- Pregnant or lactating females or females at risk of pregnancy, i. e. those not

demonstrating adequate contraception (i. e. barrier methods, intrauterine devices, hormonal treatment or sterilization). A pregnancy test is to be carried out in women of a fertile age.

- History of alcohol or drug abuse;

- Patients treated with monoamine oxidase inhibitors, tricyclic antidepressants or

beta-blockers as regular use;

- Allergy, sensitivity or intolerance to study drugs and/or study drug formulation

ingredients;

- Patients unlikely to comply with the protocol or unable to understand the

nature, scope and possible consequences of the study;

- Patients who received any investigational new drug within the last 12 weeks;

- Patients who have been previously enrolled in this study;

- At the end of the run-in period, patients will not be admitted to the treatment

period in the case of an increase of PEFR (L/sec) measured at the clinics at the end of the run-in period > 15% in respect of values measured at the start of the run-in period;

- Patients with asthma exacerbations during the run-in period will also be

excluded from the study.
