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:

There was 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)

Safety profile based on the Summary of Product Characteristics:2

Side effects

Common (≥1/100 to <1/10): pneumonia, upper respiratory tract infection, bronchitis, pharyngitis, rhinitis, sinusitis, influenza, nasopharyngitis, candidiasis of mouth and throat, urinary tract infection, headache, cough, oropharyngeal pain, constipation, arthralgia, back pain.

Other important side effects include

Uncommon (≥1/1,000 to <1/100): viral respiratory tract infection, dysgeusia, dysphonia, dry mouth, fractures, supraventricular tachyarrhythmia, tachycardia, atrial fibrillation, vision blurred, glaucoma, eye pain.

Rare (≥1/10,000 to <1/1,000): anxiety, tremor, intraocular pressure increased, muscle spasms, dysuria, hypersensitivity reactions, including anaphylaxis, angioedema, urticaria and rash; hyperglycaemia; palpitations and urinary retention.

Systemic effects: Systemic effects of ICS may occur, particularly at high doses for long periods, but much less likely than with oral corticosteroids.

Not for acute use - there are no clinical data to support the use of Trelegy Ellipta for the treatment of acute episodes of bronchospasm, or to treat an acute COPD exacerbation (i.e. as a rescue therapy).

Deterioration of disease - increasing use of short-acting bronchodilators to relieve symptoms may indicate deterioration of disease control. In the event of deterioration of COPD during treatment with Trelegy Ellipta, a re-evaluation of the patient and of the COPD treatment regimen should be undertaken. Patients should not stop therapy with Trelegy Ellipta without physician supervision since symptoms may recur after discontinuation.

This is not an exhaustive list. Please consult the Summary of Product Characteristics for a full list of adverse reactions, special warnings and precautions.
