Budesonide/formoterol maintenance and reliever therapy via Turbuhaler versus fixed-dose budesonide/formoterol plus terbutaline in patients with asthma: phase III study results.

Background And Objective: To evaluate the efficacy and tolerability of budesonide/formoterol as maintenance and reliever therapy versus budesonide/formoterol maintenance plus terbutaline in adults with persistent asthma not adequately controlled with inhaled corticosteroid (ICS) therapy alone.

Methods: In this 12-month, randomized, double-blind, parallel-group, phase III study (NCT00839800), patients (age ≥ 16 years; receiving maintenance ICS; ≥ 1 severe exacerbation in the 12 months prior to study entry) were randomized to either budesonide/formoterol 160/4.5 μg 1 inhalation twice daily plus budesonide/formoterol 160/4.

A randomised, placebo-controlled, dose-finding study of AZD9668, an oral inhibitor of neutrophil elastase, in patients with chronic obstructive pulmonary disease treated with tiotropium.

AZD9668 is a fully reversible, selective, oral inhibitor of neutrophil elastase, a protease implicated in chronic obstructive pulmonary disease (COPD). Efficacy, safety and tolerability of AZD9668 (5, 20 and 60 mg bid) were compared with placebo in a randomised, double-blind, placebo-controlled, 12-week, Phase IIb trial (NCT00949975: approved by an Investigational Review Board), in patients with symptomatic COPD receiving maintenance tiotropium. The primary endpoint was pre-bronchodilator forced expiratory volume in 1 second (FEV₁).
