Recent reports provide evidence-based guidelines for the withdrawal of inhaled corticosteroids (ICS) in COPD, but data on patients treated with ICS-based triple therapy are sparse and contradictory. We assessed the effect of ICS discontinuation on the incidence of severe exacerbation and pneumonia in a real-world population of patients with COPD who initiated triple therapy. We identified a cohort of patients with COPD treated with LAMA-LABA-ICS triple therapy during 2002–2018, age 50 or older, from the UK’s CPRD database. Subjects who discontinued ICS were matched 1:1 on time-conditional propensity scores to those continuing ICS and followed for one year. Hazard ratios (HR) of severe exacerbation and pneumonia were estimated using Cox regression. The cohort included 42,667 patients who discontinued ICS matched to 42,667 who continued ICS treatment. The hazard ratio of a severe exacerbation with ICS discontinuation relative to ICS continuation was 0.86 (95% CI: 0.78–0.95), while for severe pneumonia it was 0.96 (95% CI: 0.88–1.05). The incidence of severe exacerbation after ICS discontinuation was numerically higher than after continuation among patients with two or more exacerbations in the prior year (HR 1.09; 95% CI: 0.94–1.26) and among those with FEV 1  &lt;30% predicted (HR 1.29; 95% CI: 1.04–1.59). This large real-world study in the clinical setting of COPD treatment suggests that certain patients on triple therapy can be safely withdrawn from ICS and remain on bronchodilator therapy. As residual confounding cannot be ruled out, ICS discontinuation is not warranted for patients with multiple exacerbations and with very severe airway obstruction.
