As evidence for inhaled corticosteroids (ICS) in chronic obstructive pulmonary disease (COPD) treatment has evolved, guidelines have limited the use of ICS-based regimens.
The GOLD guidelines no longer recommend long-acting beta 2 agonist (LABA) + ICS. Patients experiencing major symptoms without further exacerbations should be switched to a long-acting muscarinic antagonist (LAMA) + LABA. To evaluate ICS withdrawal, the real-world EVELUT® study (NCT03954132) followed 463 patients with symptomatic COPD at low exacerbation risk (GOLD B) who were switched, at their physicians’ discretion, from LABA + ICS to LAMA + LABA (n=329) or triple therapy (LAMA + LABA + ICS) (n=134). At 12 weeks, marginally more patients responded to LAMA + LABA than triple therapy, leading the investigators to conclude that the switch to LAMA + LABA improved their symptoms while eliminating ICS-associated risks.
The GOLD guidelines reserve triple therapy for patients with high exacerbation risk and elevated eosinophils, but many patients receive it without clear indication. DACCORD (EUPAS4207), a real-world study, recruited patients who had received triple therapy for at least 6 months (N=1124) and, at their physicians’ discretion, continued it (n=784) or switched to LAMA + LABA (n=340). At 1 year, fewer patients had worsening of COPD with LAMA + LABA versus triple therapy (32.5% vs 55.7%). Also, significantly fewer patients had an exacerbation with LAMA + LABA versus triple therapy (18.5% vs 28.7%; P < 0.001). The investigators concluded that physicians can identify patients to de-escalate from triple therapy to LAMA + LABA with no COPD decline—and potentially better outcomes.
For patients on ICS-containing regimens, when would you consider withdrawing the ICS? If not, why?
LABA a lot more now and reserve the ICS for more severe cases. It can be a bit difficult at times to withdraw ICS from patients who are stable and on it for few years but would consider doing it.
There are clearly some patients with COPD who benefit from ICS but many who do not.
Majority of them respond very well to combination of long-acting muscarinic antagonist and long-acting beta 2 adrenergic agonist inhaler and with fewer exacerbations.
