OBJECTIVE: To evaluate the efficacy and safety of a fixed-dose, single-capsule budesonide-formoterol combination, in comparison with budesonide alone, in patients with uncontrolled asthma. METHODS: This was a randomized, double-blind, multicenter, phase III, parallel clinical trial, comparing the short-term efficacy and safety of the combination of budesonide (400 µg) and formoterol (12 µg), with those of budesonide alone (400 µg), both delivered via a dry powder inhaler, in 181 patients with uncontrolled asthma. The age of the patients ranged from 18 to 77 years. After a run-in period of 4 weeks, during which all of the patients received budesonide twice a day, they were randomized into one of the treatment groups. for 12 weeks. The treatment consisted of the administration of the medications twice a day for 12 weeks. The primary outcome measures were FEV1, FVC, and morning PEF. We performed an intention-to-treat analysis of the data. RESULTS: In comparison with the budesonide-only group patients, those treated with the budesonide-formoterol combination showed a significant improvement in FEV1 (0.12 L vs. 0.02 L; p = 0.0129) and morning PEF (30.2 L/min vs. 6.3 L/min; p = 0.0004). These effects were accompanied by good tolerability and safety, as demonstrated by the low frequency of adverse events, only minor adverse events having occurred. CONCLUSIONS: The single-capsule combination of budesonide and formoterol appears to be efficacious and safe. Our results indicate that this formulation is a valid therapeutic option for obtaining and maintaining asthma control. (ClinicalTrials.gov Identifier: NCT01676987 [http://www.clinicaltrials.gov/]).
