Study 2: description

A 12-week, double-blind, placebo-controlled study comparing SYMBICORT 80/4.5 mcg, budesonide 80 mcg, formoterol 4.5 mcg, and placebo, each administered as 2 inhalations twice daily. Most patients had mild to moderate asthma and were using low to moderate doses of inhaled corticosteroids prior to study entry. Mean number of albuterol inhalations per day at baseline for the groups receiving SYMBICORT and budesonide was 2.75 and 2.99, respectively.

SYMBICORT does NOT replace fast-acting inhalers and should not be used to treat acute symptoms of asthma

In another study, improved lung function over 52 weeks6

  • In a 52-week safety study, SYMBICORT improved predose FEV1 versus twice the recommended dosage of budesonide

Study 728: description

A 52-week, double-blind, single-dummy, parallel-group, multicenter study comparing the long-term safety of SYMBICORT 160/4.5 mcg, 4 inhalations twice daily; SYMBICORT 160/4.5 mcg, 2 inhalations twice daily; and budesonide hydrofluoroalkane 160 mcg, 4 inhalations twice daily, in 708 patients (132 randomized to receive SYMBICORT 160/4.5 mcg, 2 inhalations twice daily) ≥12 years of age with moderate to severe persistent asthma. The primary objective of this study was to assess the long-term safety of SYMBICORT and budesonide. However, spirometry (predose and 2-hour postdose FEV1) was conducted at each study visit to detect any untoward decrease in lung function over the 52-week treatment period. Additional coprimary objectives included asthma exacerbations, electrocardiograms and Holter monitoring, and morning PEF.

Delivered improved lung function within 15 minutes of the first dose and at subsequent doses2-4

Rapid improvement in FEV1 from the first to the last dose3,4

Rapid improvement in forced expiratory volume (FEV)
  • SYMBICORT delivered improved lung function within 15 minutes of the first dose and at subsequent doses
  • Within 15 minutes of the first dose of SYMBICORT, patients experienced a 15.8% mean improvement in FEV1
  • Within 15 minutes of the last dose of SYMBICORT, patients experienced an 8.7% incremental improvement in FEV1 in addition to the 9.4% maintenance effect—for a total mean improvement of 18.1% from baseline

Study 1: description

A 12-week, double-blind, placebo-controlled study comparing SYMBICORT 160/4.5 mcg, budesonide (BUD) 160 mcg, formoterol (FM) 4.5 mcg, the free combination of BUD 160 mcg plus FM 4.5 mcg in separate inhalers, and placebo, each administered as 2 inhalations twice daily. A total of 596 patients (124 randomized to receive SYMBICORT) ≥12 years of age were evaluated. Most patients had moderate to severe asthma and were using moderate to high doses of inhaled corticosteroids (ICSs) prior to study entry. Percent change for comparator arms within 15 minutes on day of randomization: BUD, 2.4%; FM, 16.9%; BUD + FM, 16.3%; placebo, 2.1%; and end of treatment: BUD, 6.0%; FM, 8.5%; BUD + FM, 17.0%; placebo, -3.0%.

*In clinical studies (Study 1 and Study 2), asthma control was defined as the coprimary efficacy end points of the 12-hour-average postdose forced expiratory volume in 1 second (FEV1) at week 2 and predose FEV1, averaged over 12 weeks. In addition, measures of asthma control included improvement in peak expiratory flow (PEF) and reduction in asthma symptoms and albuterol rescue use.

Onset of clinically significant bronchodilation (≥15% improvement in FEV1).
