Investor interest in amyloid-targeting drug candidates surged following Biogen and Eisai’s landmark results for lecanemab, an investigational monoclonal antibody for AD.  Roche and Eli Lilly, whose investigational candidates target the same protein, also experienced tremendous stock gains.  PMN310 is designed to potentially have advantages over other AD therapies due to its oligomer selectivity.
