GSK plc reports that China’s National Medical Products Administration has approved Exdensur (depemokimab) as an add-on maintenance treatment for severe asthma with an eosinophilic phenotype in patients aged 12 and older. Exdensur is described as the first and only ultra-long-acting biologic in China for this condition and is dosed twice yearly.
The approval is based on the phase III SWIFT-1 and SWIFT-2 trials, where depemokimab plus standard of care significantly reduced annualised asthma exacerbations compared with placebo plus standard of care. In SWIFT-1 and SWIFT-2, exacerbation rates fell by 58% and 48% over 52 weeks, and pooled data showed a 72% reduction in clinically significant exacerbations requiring hospital or emergency visits.
Across the SWIFT trials, depemokimab showed a safety and tolerability profile similar to placebo. GSK notes that more than 2 million people in China are affected by severe asthma and highlights that Exdensur is already approved for severe asthma, and in some regions for chronic rhinosinusitis with nasal polyps, in the US, Japan, the EU and the UK.

GSK plc reports that the European Medicines Agency has accepted for review a marketing authorisation application for bepirovirsen, an investigational antisense oligonucleotide for adults with chronic hepatitis B. The submission is backed by Phase III B‑Well 1 and B‑Well 2 trials, which met their primary endpoint and showed statistically significant, clinically meaningful functional cure rates versus standard of care.
Chronic hepatitis B affects an estimated 3.2 million people in Europe and more than 250 million worldwide, with current nucleos(t)ide analogue therapies often requiring lifelong treatment and achieving functional cure in only about 1% of patients. Bepirovirsen is designed to target hepatitis B viral RNA, reduce hepatitis B surface antigen, and stimulate the immune system, with trials indicating an acceptable safety and tolerability profile. The data will be presented at a scientific congress and submitted for peer‑reviewed publication in 2026, while bepirovirsen remains unapproved globally.
