Pipeline Updates

Prothena is advancing an early-stage pipeline of programs for a number of potential neurological indications with Bristol Myers.  PRX005 — a potential treatment for Alzheimer’s disease (AD) — is an investigational antibody that targets tau, a protein implicated in diseases including AD, frontotemporal dementia, progressive supranuclear palsy, chronic traumatic encephalopathy and other tauopathies. A phase I study was initiated in 2021, and top-line data is expected later in the year.

Prothena is also evaluating PRX012, an investigational high-potency monoclonal antibody targeting a key epitope at the N-terminus of amyloid beta (Aβ) for treating AD.   The FDA granted Fast Track designation for PRX012 for the treatment of AD. A phase I multiple ascending dose (MAD) study is expected to be initiated by year-end 2022.

The company is also developing a dual Aβ-Tau vaccine — a potential prevention and treatment for AD — to target key epitopes within Aβ and tau proteins to promote amyloid clearance and block pathogenic tau interaction. An Investigational New Drug (IND) application for the vaccine is anticipated in 2023.

The company is also evaluating prasinezumab in collaboration with Roche for the treatment of Parkinson’s disease. PRTA earned a $60 million milestone payment in 2021 upon dosing the first patient in the global phase IIb PADOVA study for prasinezumab from Roche. The study results are expected in 2024.

It is also evaluating birtamimab, a potential treatment for AL amyloidosis.  It reached a Special Protocol Assessment agreement with FDA and initiated a confirmatory phase III AFFIRM-AL study of birtamimab in Mayo Stage IV patients with AL amyloidosis in 2021. Results are expected in 2024.

Novo Nordisk (NVO - Free Report) has acquired Prothena’s clinical-stage antibody, PRX004 (now NNC6019) and a broader ATTR amyloidosis program. Prothena is eligible to receive a total aggregate of up to $1.23 billion and has received $60 million upfront payment from NVO in 2021. A phase II study of NNC6019 in patients with ATTR cardiomyopathy is being conducted by Novo Nordisk
