 -  Daily or persistent asthma symptoms.

 -  Night symptoms at least once a week.

 -  Forced expiratory volume in 1 second (FEV1) > 40% and < 80% of predicted normal value
 and continuing asthma symptoms.

 -  FEV1 increased > 12% from baseline within 30 minutes of inhaled (up to 400 mcg) or
 nebulized (up to 5 mg) salbutamol.

 -  Subject taking more than 500 mcg/day of fluticasone or equivalent associated to a
 long-acting β2-agonist.

 -  Inhaled corticosteroid and long-acting beta-2 adrenergic agonist (LABA) doses that
 remained fixed during the last 12 weeks prior to screening.

 -  Medical history of at least two episodes of asthma exacerbation treated with systemic
 corticoid or at least one severe asthma exacerbation treated with systemic corticoid
 and hospitalization or emergency room visit in the last 12 months prior to screening.

 -  Positive skin prick test (diameter of wheal > 3mm) to at least one perennial
 aeroallergen (dust mite, cat/dog dander, cockroaches), to which the subject was likely
