Pipeline

Fueled by a deep scientific expertise built over decades of research, Prothena is integrating scientific insights around protein dysregulation to advance a pipeline of therapeutic candidates for a number of neurodegenerative and rare peripheral amyloid diseases which affect millions of people and their families worldwide.

Prothena’s wholly owned programs include birtamimab for the potential treatment of AL amyloidosis and a portfolio of programs for the potential treatment of Alzheimer’s disease including PRX012 that targets Aβ (amyloid beta) and PRX123, the company’s dual Aβ-tau vaccine. Prothena’s collaborations include prasinezumab, which targets alpha-synuclein, with Roche for the potential treatment of Parkinson’s disease; coramitug (PRX004) for the potential treatment of ATTR amyloidosis with Novo Nordisk; and programs that target tau (BMS-986446/PRX005) and an undisclosed target (PRX019) with Bristol Myers Squibb for the potential treatment of neurodegenerative diseases.
