Brief summary: The purpose of this trial is to verify if the test treatment BDP 250 mcg/salbutamol 100 mcg HFA pMDI fixed combination is non-inferior to BDP 250 mcg/salbutamol 100 mcg pMDI fixed combination given with the conventional CFC propellant (Clenil® Compositum 250, Chiesi Farmaceutici) in terms of Pulmonary Function (morning PEF).

Detailed description: Asthma is a chronic inflammatory disorder of the airways and a serious public health worldwide problem, affecting people of all ages, with an estimate of 300 millions affected individuals.When uncontrolled, asthma can place severe limits on daily life, and can sometimes be fatal.

There are two major classes of inhaled therapy for the treatment of reversible obstructive airways disease: antinflammatory agents and bronchodilators. In particular, BDP 250 mcg plus salbutamol 100 mcg in fixed combination is an effective and safe method to control symptoms of persistent asthma in adults.

This study has been designed to compare the efficacy, safety and tolerability of a new BDP 250 mcg/salbutamol 100 mcg HFA pMDI fixed combination with the same CFC-formulated fixed combination, which is on the market from some decades.The HFA propelled product is developed to replace the CFC formulation already marketed according to the European Union's Committee for Proprietary Medicinal Products (CPMP) Note for Guidance (III/5378/93 - Final) in order to prevent from depletion of stratospheric ozone.

The primary objective of this trial is to demonstrate that the test treatment BDP 250 mcg/salbutamol 100 mcg HFA pMDI fixed combination is non-inferior to BDP 250 mcg/salbutamol 100 mcg pMDI fixed combination given with the conventional CFC propellant (Clenil® Compositum 250, Chiesi Farmaceutici) in terms of Pulmonary Function (morning PEF).

Given the aim of the study, the population to be monitored includes adult patients with persistent asthma according to the current guidelines. The treatment period will be preceded by a 2-week run-in period. Subjects satisfying all the inclusion and exclusion criteria will then enter the 12-week treatment period. Clinic visits will take place at the start and end of the run-in period, and after 2, 4, 8 and 12 weeks after randomisation.

Eligibility criteria: Inclusion Criteria:

1. Written informed consent obtained,
2. Male or female out-patients aged ³ 18 and \< 65 years;
3. Uncontrolled asthma defined according to the GINA 2006 "Classification of Levels of Asthma Control". This definition includes the presence of two or more of the following features (in addition to the required range of FEV1): a) daytime asthma symptoms \> twice a week; b) any limitation of activities; c) any nocturnal symptoms/awakening; b) need for reliever/rescue treatment \> twice a week. These conditions are to be based on recent medical history and are to be confirmed in the 2-week run-in period;
4. Forced expiratory volume in the first second (FEV1) ³ 60% and \< 80% of the predicted normal value;
5. Positive response to the reversibility test in the screening visit, defined as an increase of at least 12% (or, alternatively, of 200 mL) from pre-bronchodilator value in the measurement of FEV1 30 minutes following 4 puffs (4 ´ 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;
6. Non-smokers or ex-smokers with a cumulative tobacco exposure less than 5 pack-years and who have stopped smoking since more than 1 year;
7. A co-operative attitude and ability to be trained to correctly use the pMDIs;
8. At the end of the 2-week run-in period, the condition of uncontrolled asthma (see inclusion criteria No. 3) is to be confirmed by reviewing the diary cards for run-in.

Exclusion Criteria:

1. Inability to carry out pulmonary function testing;
2. Diagnosis of Chronic Obstructive Pulmonary Disease (COPD;
3. History of near fatal asthma;
4. Evidence of severe asthma exacerbation or symptomatic infection of the airways in the previous 4 weeks;
5. Three or more courses of oral corticosteroids or hospitalisation due to asthma during the previous 6 months;
6. Patients who have been treated with an inhaled corticosteroid in the previous 4 weeks;
7. Patients who have been treated with nebulized, oral, intravenous or intramuscular corticosteroids in the past 8 weeks or depot injectable corticosteroids in the past 12 weeks;
