$55 million - Remain on track and expect to deliver upcoming clinical milestones from wholly-owned and strategic partner programs over the next 15 months
“We continue to advance our programs across the pipeline to address devastating neurological and rare peripheral diseases caused by protein dysregulation which affect millions of people and their families worldwide. Our expertise in developing therapeutic approaches that target misfolded proteins to achieve clinical benefit has us well positioned with several expected milestones in the near future. We are excited for initial topline results from our ongoing Phase 1 SAD and MAD clinical trials of PRX012, an anti-amyloid beta antibody, and our IND for PRX123, a dual amyloid beta/tau vaccine, by the end of 2023,” said Gene Kinney, Ph.D., President and Chief Executive Officer, Prothena. “We also look forward to multiple milestones in 2024, including topline results from AFFIRM-AL, our confirmatory Phase 3 clinical trial of birtamimab, the first potential therapy to show a significant survival benefit in patients with Mayo Stage IV AL amyloidosis; Phase 2b results from Roche on prasinezumab; and Phase 2 results from Novo Nordisk on NNC6019.”
Third Quarter, Recent Business Highlights and Upcoming Milestones
Neurodegenerative Diseases Portfolio
Alzheimer’s Disease (AD)
PRX012, a wholly-owned potential best-in-class, next-generation subcutaneous antibody for the treatment of AD that targets a key epitope at the N-terminus of amyloid beta (Aβ) with high binding potency. Robust reduction of brain amyloid plaque has been demonstrated to likely predict clinical benefit for people with early AD. The
- Phase 1 single ascending dose (SAD) and multiple ascending dose (MAD) clinical trials are ongoing; initial topline data expected by year-end 2023
BMS-986446 (formerly PRX005), a potential best-in-class antibody for the treatment of AD that specifically targets a key epitope within the microtubule binding region (MTBR) of tau, a protein implicated in the causal human biology of AD. BMS-986446 is part of a Global Neuroscience Research and Development Collaboration with Bristol Myers Squibb.
-
Received
$55 million - Bristol Myers Squibb reported that Phase 1 data supports rapidly moving BMS-986446 into a Phase 2 clinical trial in first half 2024
PRX123, a wholly-owned potential first-in-class dual Aβ/tau vaccine designed for the treatment and prevention of AD, 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.
- Investigational new drug (IND) application expected by year-end 2023
Parkinson’s Disease (PD)
Prasinezumab, a potential first-in-class antibody for the treatment of PD designed to target a key epitope within the C-terminus of alpha-synuclein and is the focus of a worldwide collaboration with Roche.
- Roche presented data at the International Congress of Parkinson’s Disease and Movement Disorders (MDS) from the open-label extension of the PASADENA study which shows that prasinezumab slowed the progression of motor deficits (MDS-UPDRS Part III OFF state score) in early-stage PD
-
Roche completed enrollment for the Phase 2b
PADOVA clinical trial in patients with early PD (NCT04777331); topline results expected in 2024
Rare Peripheral Amyloid Diseases Portfolio
AL Amyloidosis
Birtamimab, a wholly-owned potential best-in-class amyloid depleter antibody for the treatment of AL amyloidosis designed to directly neutralize soluble toxic aggregates and promote clearance of amyloid that causes organ dysfunction and failure. Among patients with AL amyloidosis, a rare, progressive, and fatal disease, newly diagnosed individuals with advanced disease (e.g., Mayo Stage IV) are at the highest risk for early death. Birtamimab has been granted Fast Track Designation by the FDA for the treatment of patients with Mayo Stage IV AL amyloidosis to reduce the risk of mortality and has been granted Orphan Drug Designation by both the FDA and European Medicines Agency.
- Phase 3 VITAL clinical trial data published in June in Blood, the peer-reviewed journal of American Society of Hematology (ASH)
- Confirmatory Phase 3 AFFIRM-AL clinical trial in patients with Mayo Stage IV AL amyloidosis, under a Special Protocol Assessment (SPA) with the FDA with a primary endpoint of all-cause mortality at a significance level of 0.10, is ongoing (NCT04973137); topline results expected in 2024
ATTR Amyloidosis
NNC6019 (formerly PRX004), a potential first-in-class amyloid depleter antibody for the treatment of ATTR cardiomyopathy designed to deplete the pathogenic, non-native forms of the transthyretin (TTR) protein and is being developed by Novo Nordisk as part of their up to
- Phase 2 clinical trial in patients with ATTR cardiomyopathy is being conducted by Novo Nordisk (NCT05442047); topline results expected in 2024

About the Global Neuroscience Research and Development Collaboration with Bristol Myers Squibb
This global neuroscience research and development collaboration is focused on three proteins implicated in the pathogenesis of several neurodegenerative diseases, including tau, TDP-43 and an undisclosed target. BMS-986446 (PRX005) is designed to be a best-in-class anti-tau, MTBR-specific antibody for the potential treatment of Alzheimer’s disease and is the first program to advance to the clinic from this collaboration. Prothena is eligible to receive up to an additional
