Quarter in Detail

R&D expenses were $21.1 million, up 22% year over year, primarily due to higher R&D consulting expenses, increased personnel costs and elevated manufacturing expenses primarily related to PRX004, PRX012 and birtamimab programs.

General and administrative expenses came in at $11 million, up 14% year over year, primarily due to higher personnel expenses, and increased costs for directors’ and officers’ insurance premium.

As of Jun 30, 2021, Prothena had $402.5 million in cash, cash equivalents and restricted cash, and no debt.

Pipeline Updates

In July 2021, Prothena announced that Novo Nordisk (NVO - Free Report) will acquire its clinical-stage antibody, PRX004, and broader ATTR amyloidosis program. In exchange, Prothena is eligible to receive development and sales milestone payments of approximately $1.2 billion. Prothena has already received a $60-million upfront payment in the fiscal third quarter and will receive $40 million upon initiation of phase II study in ATTR cardiomyopathy patients.

The company is evaluating prasinezumab in collaboration with Roche for the treatment of Parkinson’s disease.

Meanwhile, it is advancing an early-stage pipeline of programs for a number of potential neurological indications with Bristol-Myers Squibb (BMY - Free Report) . 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.

In June 2021, Bristol Myers exercised its option under the global neuroscience research and development collaboration and entered into an exclusive U.S. license for PRX005, a potential treatment for AD. A phase I study has also been initiated with PRX005. Prothena is expected to receive $80 million from Bristol Myers Squibb in third-quarter 2021.

Prothena announced plans in February 2021 to advance birtamimab, a potential treatment for AL amyloidosis, into the confirmatory phase III AFFIRM-AL study in Mayo Stage IV patients with AL amyloidosis. The decision was based on the significant survival benefit favoring birtamimab, from the previous VITAL study in a subset of patients categorized as Mayo Stage IV at baseline and multiple in-depth discussions with the FDA.

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 investigational new drug application for the drug is anticipated in 2023.
