Triple Therapy of Fluticasone Furoate, Umeclidinium, Vilanterol- A Compelling Choice in Severe Chronic Obstructive Pulmonary Disease

Trelegy Ellipta (GlaxoSmithKlineTM) is the first single inhaler triple combination therapy comprising of umeclidinium, vilanterol and fluticasone approved by the United States Food and Drug Administration (US FDA) for patients with severe COPD in 2019. Clinical trials comparing this triple combination with dual therapy including a Long Acting β2-Agonist/Long Acting Muscarinic Antagonist (LABA/LAMA) or Long Acting β2-Agonist/Inhaled Corticosteroids (LABA/ICS) were evaluated. Triple combination did show improvement through the mean Forced Expiratory Volume per second (FEV1), St. George questionnaire, and reduced hospitalisation due to acute exacerbation of COPD. This medication should be prescribed cautiously for certain populations. Although this triple combination is used only in patients with the most advanced forms of disease who have frequent exacerbations and remain uncontrolled, there are certain additional indications that may be explored in future trials. The convenience associated with using a single device for three different classes of drugs could be its biggest trump card and it will not be surprising to see its preference among patients avoiding the need for multiple dosing. Nevertheless, it remains to be seen if this improved adherence would translate into improved outcomes such as reduced mortality in real world practice among patients with severe COPD. The availability of a single inhaler device for delivering a triple combination of LABA/LAMA/ICS is a small success story in the quest to identify better therapies for patients with severe COPD, who are so prone to repeat acute exacerbations which could eventually turn fatal.
