GSK reports that Japan's Ministry of Health, Labour and Welfare has approved Exdensur (depemokimab) for severe or refractory bronchial asthma and for chronic rhinosinusitis with nasal polyps (CRSwNP) in patients inadequately controlled on standard treatment.
Exdensur is described as the first ultra-long-acting biologic in Japan for these conditions, given as just two injections a year. In the SWIFT-1 and SWIFT-2 phase III trials, adding depemokimab to standard care cut annualised severe asthma exacerbation rates by 58% and 48% versus placebo over 52 weeks. In the ANCHOR-1 and ANCHOR-2 trials for CRSwNP, patients showed meaningful reductions in nasal polyp size and nasal obstruction scores compared with placebo.
Across these late-stage studies, depemokimab had a tolerability profile similar to placebo. This Japan approval is the third regulatory clearance for depemokimab, following prior approvals in the US and UK, and the drug is also under review in other major markets.
GSK plc reported that two senior executives acquired ordinary shares through the company’s Share Save Plan. David Redfern, President, Corporate Development, and Victoria Whyte, SVP & Company Secretary, each exercised options granted on 28 November 2022 to buy 790 ordinary shares at an option price of £11.39 per share. The transactions, both carried out on 2 January 2026 on the London Stock Exchange, reflect routine participation in an employee share plan rather than open‑market buying. These acquisitions slightly increase each executive’s direct shareholding and align them further with the company’s equity.
GSK plc reported its share capital and voting rights position as of 31 December 2025. The company’s issued share capital consisted of 4,315,445,026 ordinary shares of 31 ¼ pence each, with 240,019,489 of these shares held in treasury and therefore not carrying voting rights. As a result, the total number of voting rights in GSK is 4,075,425,537. Shareholders can use this figure to determine whether they need to notify GSK and the UK Financial Conduct Authority of any interests or changes in their shareholdings under the Disclosure Guidance and Transparency Rules.
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.
