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. The company has received $80 million option payment from Bristol Myers to execute the U.S. license agreement in 2021.  A phase I study was initiated in 2021, and top-line data is expected in 2022.

Prothena is also evaluating PRX012, an investigational high-potency monoclonal antibody targeting a key epitope at the N-terminus of amyloid beta (Aβ) for the treatment of AD.  An investigational new drug application (IND) is expected in the ongoing quarter.

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 for promoting amyloid clearance as well as blockade pathogenic tau interaction. An IND for the vaccine is anticipated in 2023.

The company is also evaluating prasinezumab in collaboration with Roche (RHHBY - Free Report) for the treatment of Parkinson’s disease. PRTA earned $60 million milestone payment in 2021 upon dosing the first patient in the global phase IIb PADOVA study for prasinezumab from Roche.

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

Novo Nordisk (NVO - Free Report) has acquired Prothena’s clinical-stage antibody, PRX004, and 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. Novo Nordisk is expected to initiate a phase II trial in the first half of 2022 on PRX004 for the treatment of ATTR cardiomyopathy.
