GSK Depemokimab accepted for review by EMA for use in asthma with type 2 inflammation, CRSwNP

Depemokimab, a monoclonal antibody that targets interleukin-5 (IL-5), is a ultra-long-acting biologic to be evaluated in phase III trials and be accepted for regulatory review for use in these conditions. Depemokimab's extended half-life, high-binding affinity and potency, support six month (26 week) dosing regimens based on results from the SWIFT and ANCHOR trials. In asthma patients and patients with CRSwNP, these trials showed depemokimab could offer sustained inhibition of a key driver of their disease, and help achieve key clinical outcomes with a dosing schedule of just two injections per year. Longer intervals between doses have been shown to overcome barriers to optimal care such as patient adherence.

IL-5 is a key cytokine (protein) in type 2 inflammation. Type 2 inflammation is typically identified by blood eosinophil count and is an underlying driver in many diseases. This type of inflammation is present in the majority of patients with difficult to treat asthma and can lead to exacerbations and hospitalisation. Type 2 inflammation is also present in up to 80% of people with CRSwNP and is associated with more severe disease and symptoms.

In Europe, more than 42 million people are estimated to have asthma, which contributes to the significant burden this condition has on the lives of patients and healthcare resources, with an estimated annual societal cost of 46 billion euros. CRSwNP is a chronic condition that affects up to 4% of the general population, of whom 40% have uncontrolled disease.

Depemokimab is currently not approved in any country.
