Pipeline Updates from PRTA
Prothena is evaluating PRX012 — a wholly owned investigational next-generation subcutaneous, single-injection once-monthly antibody delivered subcutaneously targeting a key epitope at the N-terminus of amyloid beta (Aβ) — for treating Alzheimer’s Disease (AD).
Initial phase I single ascending dose and multiple ascending dose data support once-monthly subcutaneous administration and ongoing evaluation in MAD cohorts.
Prothena has enrolled approximately 260 patients in the ongoing ASCENT clinical studies on PRX012. Prothena expects to report multiple clinical readouts starting mid-2025.
Prothena is advancing an early-stage pipeline of programs for several potential neurological indications with BMY.
BMS-986446 (formerly PRX005) is designed to be a best-in-class anti-tau, MTBR-specific antibody for the potential treatment of AD.
Bristol Myers continues to enroll in the ongoing phase II study on BMS-986446 in approximately 475 patients with early AD. The study is expected to be completed in 2027.
BMY is responsible for all development, manufacturing and commercialization of BMS-986446.
PRX019, a potential treatment of neurodegenerative diseases with an undisclosed target, is also being developed in collaboration with BMY. PRTA has initiated a phase I first-in-human clinical trial on PRX019 to evaluate the safety, tolerability, immunogenicity, and pharmacokinetics of single ascending and multiple doses in healthy adults.
Prothena is also developing a dual Aβ-Tau vaccine, PRX123, a potential prevention and treatment for AD. It is a dual-target vaccine targeting key epitopes within the N-terminus of Aβ and MTBR-tau, designed to promote amyloid clearance and block the transmission of pathogenic tau. The FDA cleared an investigational new drug application.
The regulatory body granted Fast Track designation to PRX123 for the treatment of AD. Prothena expects to update plans for the phase I study in 2025.
The company is evaluating prasinezumab, in collaboration with Roche, for the treatment of Parkinson’s disease (PD).
A phase II study, PASADENA, is being conducted by Roche in patients with early PD. Data from the study showed that patients taking prasinezumab continued to show reduced motor and functional progression compared with real-world data after four years.
Top-line results from the phase IIb PADOVA study, which has completed enrollment, are expected in the ongoing quarter.
Prothena is also evaluating birtamimab, a wholly-owned potential treatment for AL amyloidosis. PRTA reached a Special Protocol Assessment agreement with the FDA and initiated a confirmatory phase III AFFIRM-AL study of birtamimab in Mayo Stage IV patients with AL amyloidosis. Top-line results from the study are expected in the first half of 2025.
Novo Nordisk acquired Prothena’s clinical-stage antibody, Coramitug (formerly PRX004), a potential first-in-class amyloid depleter antibody for the treatment of ATTR amyloidosis with cardiomyopathy.
NVO is conducting an ongoing phase II study in patients with ATTR cardiomyopathy. The study has completed enrollment of approximately 99 patients and top-line data from the same is expected in the first half of 2025.
