Arrowhead Pharmaceuticals Inc. has filed a request for regulatory clearance in New Zealand to initiate a phase I/IIa trial of ARO-MAPT, the company’s investigational RNA interference (RNAi) therapeutic being developed as a potential treatment for tauopathies, including Alzheimer’s disease.
Researchers at Sanofi SA have developed a promising gene therapy approach targeting the microtubule-associated protein tau (MAPT) for the treatment of Alzheimer’s disease.
Switch Therapeutics Inc. has announced its first development candidate, a liver-sparing APOE (apolipoprotein E) RNAi therapy for treatment of Alzheimer’s disease in APOE4 carriers. Switch’s conditionally activated siRNA (CASi)-APOE program is designed to knock down APOE in the CNS without affecting APOE in the liver, where it plays a vital role in systemic lipid homeostasis.
Tau protein aggregates are present in a group of disorders, collectively termed the tauopathies. Alzheimer's disease is the most common of those disorders, while frontotemporal dementia is most strongly linked to tau. Now, a map of the proteins that interact with tau and how those interactions differ between normal and disease-associated tau protein could give new clues on how the protein causes damage in neurodegenerative disorders, and on how to treat or prevent that damage.
