Rhea-AI Filing Summary

GSK plc reports that the European Commission has approved Nucala (mepolizumab) as an add-on maintenance treatment for adults with uncontrolled chronic obstructive pulmonary disease (COPD) characterised by raised blood eosinophils despite inhaled triple therapy (ICS, LABA, LAMA).

The approval is based on the phase III MATINEE trial, where mepolizumab reduced the annualised rate of moderate or severe COPD exacerbations versus placebo plus standard of care, with a rate ratio of 0.79 and annualised exacerbation rates of 0.80 versus 1.01. MATINEE also showed a reduction in exacerbations requiring emergency department visits and/or hospitalisation, with a rate ratio of 0.65 and annualised rates of 0.13 versus 0.20.

Nucala is described as the first and only monthly biologic in the EU evaluated in a wide COPD population with an eosinophilic phenotype, and is now approved in Europe across five indications driven by type 2 inflammation, including COPD, severe asthma, chronic rhinosinusitis with nasal polyps, eosinophilic granulomatosis with polyangiitis, and hypereosinophilic syndrome.

Positive

  • European Commission approval of Nucala for eosinophilic COPD adds a new indication in a large disease area, based on phase III MATINEE data showing reduced moderate/severe exacerbations and fewer exacerbations requiring emergency department visits and/or hospitalisation versus placebo plus standard of care.

Negative

  • None.

Insights

EU COPD approval for Nucala expands GSK’s respiratory biologics franchise.

The European Commission approval of Nucala for eosinophilic COPD adds a fifth European indication for mepolizumab and strengthens GSK’s respiratory portfolio. The decision is grounded in the phase III MATINEE trial, which showed fewer moderate or severe exacerbations versus placebo plus inhaled triple therapy.

In MATINEE, mepolizumab achieved a rate ratio of 0.79% for annualised moderate/severe exacerbations, and 0.65% for exacerbations requiring emergency department visits and/or hospitalisation, with similar adverse event rates to placebo. This suggests a favourable benefit–risk profile in the studied eosinophilic COPD population.

Because Nucala is already approved for COPD in the US, UK, and China, this EU label extension aligns major markets and may support broader clinical adoption in type 2 inflammation–driven COPD. Future disclosures in company materials may clarify uptake and contribution relative to GSK’s wider respiratory medicines.

Nucala (mepolizumab) approved by the European Commission for the treatment of chronic obstructive pulmonary disease (COPD)
 
Approval based on results from MATINEE showing significant reduction in the rate of moderate/severe exacerbations versus placebo
Nucala is the first and only monthly biologic in the EU evaluated in a wide COPD population with an eosinophilic phenotype
MATINEE data showed a reduction in exacerbations leading to emergency department visits and/or hospitalisations versus placebo
 
 
GSK plc (LSE/NYSE: GSK) today announced the European Commission has approved Nucala (mepolizumab), a monoclonal antibody targeting interleukin-5 (IL-5), in adults as an add-on maintenance treatment for uncontrolled COPD characterised by raised blood eosinophils on a combination of an inhaled corticosteroid (ICS), a long-acting beta2-agonist (LABA), and a long-acting muscarinic antagonist (LAMA).
 
The approval was based on data from the positive MATINEE phase III trial in which mepolizumab showed a clinically meaningful and statistically significant reduction in the annualised rate of moderate/severe exacerbations versus placebo plus standard of care in a wide spectrum of COPD patients with an eosinophilic phenotype.1
 
COPD affects over 390 million people, including about 40 million in Europe.2,3 Globally, it is projected to be the leading cause of hospital admissions over the next decade.4 If hospitalised due to COPD, one in ten patients will die during the stay, up to one in four over the next year and half will lose their lives within five years.5,6 Nucala is the first biologic with pre-specified phase III data showing a reduction in the annualised rate of exacerbations leading to emergency department visits and/or hospitalisation versus placebo.1
 
Kaivan Khavandi, SVP, Global Head, Respiratory, Immunology & Inflammation R&D, GSK, said: "For the first time, adults with uncontrolled COPD characterised by raised blood eosinophils in the EU will have the option for a monthly biologic shown to significantly reduce exacerbations, which can lead to irreversible lung damage, hospitalisations and emergency department visits. Nucala could offer relief to the millions of Europeans who need additional options beyond inhaled triple therapy to manage their COPD."
 
Susanna Palkonen, Director, European Federation of Allergy and Airways Diseases Patients' Associations (EFA), said: "The burden for patients living with COPD is immense, especially for those facing continued exacerbations and repeated hospitalisations. We welcome, and our community celebrates, new treatment options for COPD patients as they are desperately needed."
 
In MATINEE, mepolizumab demonstrated a statistically significant reduction in the annualised rate of moderate or severe exacerbations compared with placebo, both in addition to inhaled triple therapy [rate ratio 0.79, 95% confidence interval (0.66, 0.94), P=0.01] (AER mepolizumab = 0.80 exacerbations per year versus placebo = 1.01).1 The MATINEE trial studied mepolizumab in a wide spectrum of patients with an eosinophilic phenotype including chronic bronchitis, emphysema only or a combination of both.
 
In a pre-defined secondary endpoint, the annualised rate of COPD exacerbations requiring ED visits and/or hospitalisation was reduced in the mepolizumab group when compared with placebo [rate ratio 0.65; 95% CI (0.43, 0.96) nominally significant after adjustment for multiplicity] (AER mepolizumab = 0.13 exacerbations per year versus placebo = 0.20).1 The incidence of adverse events were similar between mepolizumab and placebo (mepolizumab vs placebo: 74% vs 77%). The full results from the MATINEE phase III trial were published in The New England Journal of Medicine in April 2025 with further data presented at the 2025 American Thoracic Society International Congress.1
 
In addition to COPD, Nucala is approved in Europe across four other diseases driven by underlying type 2 inflammation, including severe asthma, chronic rhinosinusitis with nasal polyps (CRSwNP), eosinophilic granulomatosis with polyangiitis (EGPA), and hypereosinophilic syndrome (HES). It has also been approved for COPD in the US, UK, and China.
 
About COPD
COPD is a progressive and heterogeneous inflammatory lung disease that includes chronic bronchitis and/or emphysema.2 It affects more than 390 million people globally and is the third leading cause of death.2,7 Patients with COPD experience persistent respiratory symptoms such as breathlessness, cough, and sputum along with progressive airflow obstruction due to the chronic inflammation, that impact daily life.2
 
Despite inhaled triple therapy, many patients experience persistent symptoms and exacerbations.8 A proportion of these patients have elevated type 2 inflammation, characterised by raised BEC. This inflammation contributes to the higher risk of exacerbations, or acute episodes of worsening COPD symptoms, which can result in hospitalisation and irreversible lung damage.2 Early intervention is important in preventing exacerbations and cumulative lung damage.2
 
About MATINEE
MATINEE is a phase III, randomised (1:1), double-blind, parallel-group trial assessing the efficacy and safety of mepolizumab 100 mg as add-on therapy, administered subcutaneously every 4 weeks versus placebo in addition to optimal inhaled triple therapy (dual long-acting bronchodilators plus inhaled corticosteroid).1,8 MATINEE assessed the efficacy and safety of mepolizumab in patients with COPD with evidence of type 2 inflammation, characterised by a raised blood eosinophil count (≥300 cells/µL). Patients could participate with a range of clinical presentations of COPD including chronic bronchitis, emphysema only or a combination of both. The full analysis of MATINEE included 403 patients enrolled on the mepolizumab arm and 401 on placebo, all of whom had experienced exacerbations in the previous year despite receiving optimised inhaled maintenance therapy.1

FAQ

What did GSK (GSK) announce about Nucala in Europe?

GSK announced that the European Commission approved Nucala (mepolizumab) as an add-on maintenance treatment for adults with uncontrolled COPD characterised by raised blood eosinophils despite inhaled triple therapy, expanding Nucala’s approved indications in Europe to five type 2 inflammation–driven diseases.

What is the MATINEE trial mentioned in GSK’s 6-K filing?

MATINEE is a phase III, randomised, double-blind trial evaluating mepolizumab 100 mg every 4 weeks versus placebo on top of optimal inhaled triple therapy in COPD patients with raised blood eosinophils. It enrolled 403 patients on mepolizumab and 401 on placebo who had prior exacerbations.

How effective was Nucala in reducing COPD exacerbations in MATINEE?

In MATINEE, mepolizumab significantly reduced the annualised rate of moderate or severe COPD exacerbations versus placebo, with a rate ratio of 0.79 and annualised rates of 0.80 versus 1.01 per year, demonstrating a clinically meaningful and statistically significant benefit in the studied eosinophilic COPD population.

Did Nucala reduce COPD hospitalisations in the MATINEE study?

A predefined secondary endpoint showed that mepolizumab reduced the annualised rate of COPD exacerbations requiring emergency department visits and/or hospitalisation versus placebo, with a rate ratio of 0.65 and annualised rates of 0.13 versus 0.20 per year, described as nominally significant after adjustment for multiplicity.

What safety profile did Nucala show in COPD patients in MATINEE?

In MATINEE, the incidence of adverse events was similar between treatment groups, with 74% of patients on mepolizumab and 77% on placebo experiencing adverse events. This indicates a broadly comparable safety profile to placebo in COPD patients receiving optimised inhaled maintenance therapy.

For which conditions is Nucala currently approved in Europe?

Nucala is approved in Europe for five indications driven by type 2 inflammation: severe asthma, chronic rhinosinusitis with nasal polyps, eosinophilic granulomatosis with polyangiitis, hypereosinophilic syndrome, and COPD characterised by raised blood eosinophils, all supported by clinical data across these disease settings.

How common is COPD according to the data cited by GSK?

The content states that COPD affects over 390 million people globally, including about 40 million in Europe, and is described as the third leading cause of death worldwide, underlining the significant disease burden that therapies like Nucala aim to address in specific eosinophilic patient subsets.
