WVE‐005, a stereopure antisense oligonucleotide for MAPT silencing in tauopathies

Background: Tau is a neuronal scaffolding protein which aggregates intracellularly upon hyperphosphorylation to form neurofibrillary tangles (NFT). NFTs are a hallmark of various microtubule associated protein tau (MAPT)‐associated neurodegenerative diseases, including Alzheimer’s disease, frontotemporal dementia, and progressive supranuclear palsy. Currently, there is no approved treatment targeting Tau pathology, nor any other disease‐modifying therapy for these diseases. Wave Life Sciences has developed a stereopure antisense oligonucleotide to reduce MAPT expression in patients with MAPT‐associated neurodegenerative diseases.
