SAN FRANCISCO & LONDON--(BUSINESS WIRE)--GSK plc (LSE/NYSE: GSK) and Aiolos Bio, Inc. (Aiolos) today announced that they have entered into an agreement under which GSK will acquire Aiolos, a clinical-stage biopharmaceutical company focused on addressing the unmet treatment needs of patients with certain respiratory and inflammatory conditions, for a $1 billion upfront payment and up to $400 million in certain success-based regulatory milestone payments.
The acquisition provides GSK with access to Aiolos’ AIO-001, a potentially best-in-class, long-acting anti-thymic stromal lymphopoietin (TSLP) monoclonal antibody ready to enter phase II clinical development for the treatment of adult patients with asthma, with potential for additional indications including chronic rhinosinusitis with nasal polyps. AIO-001 was exclusively licensed to Aiolos outside of Greater China by Jiangsu Hengrui Pharmaceuticals Co., Ltd. (Hengrui).
Tony Wood, Chief Scientific Officer, GSK, said: “We have a proud heritage and deep development expertise in respiratory medicines, especially addressing diseases driven by IL-5 with high levels of eosinophils or high T2 inflammation. Adding AIO-001, a potentially best-in-class medicine targeting the TSLP pathway, could expand the reach of our current respiratory biologics portfolio, including to the 40% of severe asthma patients with low T2 inflammation where treatment options are still needed.”1
