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.

GSK plc has entered into an agreement with the U.S. Administration to lower the cost of its prescription medicines for American patients, including its broad respiratory portfolio used by more than 40 million people in the U.S. with asthma and COPD. The agreement delivers on all four actions requested by President Trump in his July 31 letter, including lowering prices for certain medicines in Medicaid and launching new products with a more balanced pricing approach across developed nations.

GSK will also offer most of its inhaled respiratory portfolio and other products through a direct purchasing platform that can provide savings of up to 66% for patients. As part of the President's Strategic Active Pharmaceutical Ingredients Reserve, GSK will secure a U.S. reserve of albuterol, a key ingredient in many inhalers. The agreements cover both GSK and ViiV Healthcare, clarify the future U.S. pricing framework, and exclude them from s232 tariffs for three years. GSK reiterates its plan to invest more than $30bn in U.S. R&D and manufacturing over five years, including $2bn of new commitments that are expected to create hundreds of highly skilled U.S. jobs.

GSK plc reports that the US Food and Drug Administration has approved Exdensur (depemokimab-ulaa) as an add-on maintenance treatment for severe asthma with an eosinophilic phenotype in patients aged 12 and older.

The ultra-long-acting biologic is given just twice a year and, in the phase III SWIFT-1 and SWIFT-2 trials, reduced annualised asthma exacerbations by 58% and 48% versus placebo over 52 weeks, on top of standard care. A pooled analysis showed a 72% reduction in clinically significant exacerbations requiring hospital or emergency visits, with a side-effect profile similar to placebo.

GSK notes that around 2 million Americans live with severe asthma and many remain uncontrolled, and sees Exdensur as a way to offer longer-lasting protection with fewer injections.

GSK plc reports that UK regulators have granted marketing authorisation for Exdensur (depemokimab), the first ultra-long-acting biologic with twice-yearly dosing for respiratory disease. In the UK it is approved as an add-on treatment for severe asthma with type 2 inflammation in patients 12 and older and as add-on therapy for adults with severe chronic rhinosinusitis with nasal polyps when steroids or surgery are not enough.

The SWIFT phase III asthma trials showed a 54% reduction in clinically significant exacerbations over 52 weeks and a 72% reduction in attacks leading to hospitalisation or emergency visits versus placebo. ANCHOR phase III trials in nasal polyps showed meaningful improvements in polyp size and nasal obstruction, and safety was similar to placebo. This is the first global approval for Exdensur, with regulatory decisions expected in the US, Japan, EU and China starting in December 2025 through H1 2026.
