NOVEL START TRIAL : CONTROLLED TRIAL OF BUDESONIDEFORMOTEROL AS NEEDED FOR MILD ASTHMA Beasley RD et al. NEJM. 2019; 380(21): 2020 -2030.
ICS use is low as maintenance therapy for mild asthma An ICS + LABA takes advantage of a patient’s natural response to use therapy when symptomatic PURPOSE Two previous clinical trials have been done showing efficacy and safety in using budesonide-formoterol as needed These two trials had high internal validity, but low external validity Novel START trial was designed to overcome limitations of previous 2 trials Beasley RD et al. NEJM. 2019; 380(21): 2020 -2030.
PREVIOUS TRIALS SYGMA-1 SYGMA-2 • Conclusion: inhaled budesonideformoterol when used as needed was superior to terbutaline, but was inferior to budesonide • Conclusion: inhaled budesonideformoterol was noninferior to the budesonide maintenance therapy for severe exacerbation • Bateman E et al. NEJM. 2018; 378(20): 1877 -1887.
RESULTS: PRIMARY OUTCOME Annualized Exacerbation Rate * * P < 0. 05 0. 4 0. 35 0. 3 0. 25 0. 175 0. 2 0. 195 0. 1 0. 05 0 Albuterol Group Budesonide Maintenance Group Budesonide-Formoterol Group Beasley RD et al. NEJM. 2019; 380(21): 2020 -2030.
AUTHOR’S CONCLUSIONS • Among patients with mild asthma, the risk of asthma exacerbations was lower with budesonide-formoterol used as needed than with albuterol used as needed Beasley RD et al. NEJM. 2019; 380(21): 20202030.
