Abstract

Aducanumab (aducanumab-avwa; Aduhelm™) is a human, immunoglobulin gamma 1 (IgG1) monoclonal antibody directed against aggregated soluble and insoluble forms of amyloid β. It has been developed by Biogen under license from Neurimmune for the treatment of Alzheimer's disease. Alzheimer’s disease is characterised by the accumulation of extracellular amyloid β as neuritic plaques and congophilic angiopathy, as well as the intracellular accumulation of abnormally phosphorylated tau in the form of neurofibrillary tangles. Aducanumab reduces amyloid β plaque levels in a dose- and time-dependent manner. In June 2021, aducanumab received its first approval in the US for the treatment of Alzheimer’s disease. Aducanumab is under regulatory review in Japan and in Europe. Its long-term safety and tolerability is being evaluated in a multinational phase 3 clinical study in patients with early Alzheimer’s disease (mild cognitive impairment and mild Alzheimer’s disease). This article summarizes the milestones in the development of aducanumab leading to this first approval for Alzheimer’s disease.
