GSK (GSK) secures China Nucala approval for blood eosinophilic COPD
Rhea-AI Filing Summary
GSK reports that China’s National Medical Products Administration has approved Nucala (mepolizumab) as an add-on maintenance treatment for adults with chronic obstructive pulmonary disease (COPD) that remains inadequately controlled and is characterised by raised blood eosinophils. The decision is based on positive phase III MATINEE and METREX trials, where mepolizumab plus standard care produced a statistically significant reduction in the annual rate of moderate or severe COPD exacerbations versus placebo, including events leading to emergency department visits and hospitalisation.
Nucala is described as the first and only monthly biologic in China studied in a broad COPD population with blood eosinophil counts starting at 150 cells/µL. GSK notes that around 100 million people in China are living with COPD and that among patients who continue to exacerbate despite inhaled triple therapy, about 67% have blood eosinophil counts above 150 cells/µL, suggesting a substantial segment of patients who may be eligible for this new add-on treatment option.
Positive
- Nucala wins COPD approval in China, adding an eosinophilic COPD indication in a market with around 100 million people living with the disease.
- Phase III data support the label, with MATINEE and METREX showing statistically significant reductions in moderate/severe exacerbations versus placebo plus standard care.
Negative
- None.
Insights
China COPD approval broadens Nucala’s label into a large, high-need market.
The approval of Nucala for eosinophilic COPD in China adds a new indication in a country where around 100 million people live with COPD. The label targets adults with inadequately controlled disease despite inhaled triple therapy and raised blood eosinophils, aligning with the patient populations in the phase III MATINEE and METREX trials.
Those trials showed statistically significant reductions in annualised moderate or severe exacerbations versus placebo plus standard of care, with MATINEE also reporting fewer exacerbations requiring emergency department visits and/or hospitalisation. The filing highlights that about 67% of patients who continue to exacerbate on triple therapy have blood eosinophil counts above 150 cells/µL, matching the eosinophilic phenotype for which mepolizumab was studied.
Nucala is already approved in China for severe eosinophilic asthma and other eosinophilic conditions, and in the US for COPD, so this decision extends an existing biologic franchise into a large COPD population. Future disclosures in company communications and filings may provide quantitative detail on uptake in this indication and any contribution to overall respiratory portfolio performance.
FAQ
What key development did GSK (GSK) report regarding Nucala in China?
GSK reported that China’s National Medical Products Administration has approved Nucala (mepolizumab) as an add-on maintenance treatment for adult COPD patients with inadequately controlled disease characterised by raised blood eosinophils.
How effective was Nucala in the MATINEE and METREX COPD trials cited by GSK (GSK)?
In both MATINEE and METREX, mepolizumab plus standard care produced a clinically meaningful and statistically significant reduction in the annualised rate of moderate or severe COPD exacerbations compared with placebo plus standard of care.
Why is the eosinophil threshold of 150 cells/µL important in GSK’s (GSK) Nucala COPD approval?
Nucala is described as the first monthly biologic in China evaluated in COPD patients with blood eosinophil counts starting at 150 cells/µL. GSK notes that about 67% of patients who still exacerbate despite inhaled triple therapy have blood eosinophil counts above this level.
For which other conditions is Nucala already approved in China according to GSK (GSK)?
GSK states that mepolizumab is already approved in China as an add-on treatment for severe eosinophilic asthma in adults and adolescents 12 years and older, chronic rhinosinusitis with nasal polyps, and eosinophilic granulomatosis with polyangiitis.
What safety profile did Nucala show in the COPD trials reported by GSK (GSK)?
Across the MATINEE and METREX phase III trials, GSK reports that the incidence of adverse events was similar between the mepolizumab and placebo groups.
How does GSK (GSK) describe the impact of COPD in China in this report?
GSK cites data indicating around 100 million people in China have COPD and that COPD deaths in China account for over 30% of global COPD mortality, underscoring the disease burden.
