Acumen announced the nomination of two development candidates in its Enhanced Brain Delivery, or EBD, program as treatments for AD. Building on preclinical data from both in vitro and in vivo studies, the company has exercised its option with JCR Pharmaceuticals as part of its previously signed agreement and will advance both candidates combining Acumen's AbetaO-selective antibody expertise and JCR's validated transferrin-receptor-targeting blood-brain barrier-penetrating technology, termed J-Brain Cargo. By selecting these two candidates, the company is expanding its optionality by nominating a bispecific antibody derived from sabirnetug as well as one based on a novel, next generation AbetaO-selective antibody with differentiated properties, known as ACU234.
