Trial drug aims to halt Alzheimer's before symptoms with monthly infusions
A Roche-developed drug called trontinemab, a next-generation antibody given as monthly infusions, may remove brain plaques more effectively and could stop or prevent Alzheimer's before symptoms, with a landmark trial enrolling about 1,600 people aged 55+ at high risk and using blood biomarkers like p-tau217 to identify those most likely to benefit, while aiming to improve safety compared with earlier drugs such as lecanemab and donanemab.
