Published:12th Dec 2023

AstraZeneca has entered into a definitive agreement to acquire Icosavax, Inc., a US-based clinical-stage biopharmaceutical company focused on developing differentiated, high-potential vaccines using an innovative, protein virus-like particle (VLP) platform.

The proposed acquisition will build on AstraZeneca’s expertise in respiratory syncytial virus (RSV), strengthening AstraZeneca’s Vaccines & Immune Therapies late-stage pipeline with Icosavax’s lead investigational vaccine candidate, IVX A12. IVX-A12 is a potential first-in- class, Phase III-ready, combination protein VLP vaccine which targets both RSV and human metapneumovirus (hMPV), two leading causes of severe respiratory infection and hospitalisation in adults 60 years of age and older and those with chronic conditions such as cardiovascular, renal and respiratory disease. There are currently no treatments or preventative therapies for hMPV and no combination vaccines for RSV. IVX A12 is the most advanced investigational vaccine targeting both RSV and hMPV and has a differentiated profile versus currently approved RSV vaccines. Phase II data demonstrate that IVX A12 elicits robust immune responses against both RSV and hMPV one month after vaccination and reconfirm previous immunogenicity data seen in the Phase I trial.
