There is now UK head-to-head real-world data for Trelegy Ellipta (FF/UMEC/VI) versus Trimbow (BEGF) pMDI1
Looking for real-world evidence vs Trixeo (BUD/GLY/FOR)?
Trelegy Ellipta (fluticasone furoate/umeclidinium/vilanterol) is indicated as a maintenance treatment in adult patients with moderate to severe chronic obstructive pulmonary disease (COPD) who are not adequately treated by a combination of an inhaled corticosteroid (ICS) and a long‑acting beta‑2 agonist (LABA), or combination of a long‑acting muscarinic antagonist (LAMA) and a LABA2
Real-world retrospective analysis of UK Clinical Practice Research Datalink (CPRD), comparing the effectiveness and safety of two licensed SITTs in COPD. Mean follow-up: 6.7 months. Study cohort included patients prescribed a SITT between September 2014 to March 2021. The efficacy and safety of Trelegy has been evaluated in two RCTs, IMPACT & FULFIL. For further information please refer to the SmPC. Interpretation of RWE is subject to limitations and may not be generalisable
Primary effectiveness outcome:
In over 74,000 UK patients (age ≥40) with COPD requiring step-up to triple therapy, an independent real-world observational study showed:
Trelegy Ellipta significantly reduced the risk of moderate-severe exacerbations vs Trimbow pMDI by 9% over 12 months1
Adjusted HR: 0.91 (95% CI: 0.89, 0.93). One-year cumulative incidence of first moderate–severe exacerbation: Trelegy Ellipta: 60.54% (n=34,825); Trimbow pMDI: 64.12% (n=39,288)
Adjusted by fine stratification weights from the probability of treatment propensity scores
Primary safety outcome:
No significant difference in the risk of severe pneumonia requiring hospitalisation with Trelegy Ellipta vs Trimbow pMDI in the overall population over 12 months1
Adjusted HR: 1.06 (95% CI 0.99, 1.13). Rate per 100 patient-years: Trelegy Ellipta: 9.9 (n=34,825); Trimbow pMDI: 9.3 (n=39,288)
Adjusted by fine stratification weights from the probability of treatment propensity scores
