    Prothena Reports First Quarter 2021 Financial Results and Provides Updated Financial Guidance and R&D Update

    Net cash used in operating and investing activities was $33.7 million in the first quarter; quarter-end cash and restricted cash position of $345.7 million provides funding to advance the R&D pipeline Announced confirmatory Phase 3 AFFIRM-AL study of birtamimab in Mayo Stage IV patients with AL amyloidosis under SPA agreement with FDAAchieved $60 million milestone from Roche for first patient dosed in Phase 2b PADOVA study of prasinezumab in patients with early Parkinson’s diseaseHighlighted data in oral presentations at AD/PD in March and AAN in April for three programs in our neurodegenerative and rare peripheral amyloid pipeline DUBLIN, Ireland, May 11, 2021 (GLOBE NEWSWIRE) -- Prothena Corporation plc (NASDAQ:PRTA), a late-stage clinical company with a robust pipeline of novel investigational therapeutics built on protein dysregulation expertise, today reported financial results for the first quarter of 2021. In addition, the Company provided an update on its R&D programs and 2021 financial guidance. “We recently welcomed Hideki Garren to Prothena as Chief Medical Officer and look forward to his expertise contributing to our transition to a fully integrated research, development and commercial biotechnology company,” said Gene Kinney, Ph.D., President and Chief Executive Officer of Prothena. “The oral presentations at AD/PD and AAN highlight the continued translation of our differentiated protein dysregulation scientific platform from preclinical findings to clinical benefit for patients across multiple programs in our portfolio. We remain on track for significant news flow this year with the planned initiation of three late-stage clinical studies for birtamimab, prasinezumab and PRX004. We will advance two programs in our Alzheimer’s portfolio towards the clinic over the next 12 months, with IND filings for our anti-tau PRX005 and anti-abeta PRX012 programs, designed to be best-in-class treatments for Alzheimer’s disease. Additionally, our cash position was strengthened by our public offering in March and will be further bolstered when we receive the $60 million milestone earned from Roche. Together this enhances our ability to fund the company through multiple key clinical milestones.” First Quarter and Recent Highlights: Birtamimab, a potential treatment for AL amyloidosis, is a humanized monoclonal antibody designed to directly neutralize soluble toxic aggregates and promote clearance of amyloid that causes organ dysfunction and failure 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 (HR=0.413, p=0.025, over 9 months), and multiple in-depth discussions with the U.S. Food and Drug Administration (FDA), Prothena announced plans in February 2021 to advance birtamimab into the confirmatory Phase 3 AFFIRM-AL study in Mayo Stage IV patients with AL amyloidosis. AFFIRM-AL is a global, registration-enabling Phase 3 study that will be conducted under a Special Protocol Assessment (SPA) agreement with FDA to enable registration at p≤0.10 for the primary endpoint of all-cause mortality. Prasinezumab, a potential treatment for Parkinson’s disease, is a humanized monoclonal antibody designed to target a key epitope within the C-terminus of alpha-synuclein and is the focus of the worldwide collaboration with Roche $60 million milestone earned with first patient dosed in PADOVA study in the second quarterTwo oral presentations by Roche at the 15th International Conference on Alzheimer’s and Parkinson’s Diseases (AD/PD 2021) released new data from Part 1 of the Phase 2 PASADENA study. The first presentation highlighted newly presented data from a pre-specified exploratory subgroup analysis showing slowing of clinical decline with prasinezumab was more evident in subgroups with more rapid disease progression. Separately, new digital biomarker data presented from Roche’s remote monitoring technology used in the study was consistent with a potential disease modifying effect of prasinezumab in slowing Parkinson’s disease progression. PRX004, a potential treatment for ATTR amyloidosis, is a humanized monoclonal antibody designed to deplete the pathogenic, non-native forms of the TTR protein Oral presentation at the American Academy of Neurology (AAN) 2021 Virtual Meeting featuring results from the Phase 1 study of PRX004 in ATTR amyloidosis. PRX004 showed favorable results as demonstrated by slowing of neuropathy progression for all 7 evaluable patients at 9 months, including improvement in neuropathy in 3 of the 7 patients, and improved cardiac systolic function for all 7 patients. In this Phase 1 study, PRX004 was found to be generally safe and well tolerated across all dose levels. 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 (FTD), progressive supranuclear palsy (PSP), chronic traumatic encephalopathy (CTE) and other tauopathies. Oral presentation at AD/PD 2021 highlighting new preclinical data demonstrating that targeting an epitope within the microtubule binding region (MTBR) of tau with PRX005 resulted in superior attributes for the potential treatment of AD. PRX005 demonstrated significant inhibition of cell-to-cell transmission and neuronal internalization in vitro and in vivo, and slowed pathological progression in a tau transgenic mouse model.

Research and development (R&D) expenses totaled $21.1 million for the first quarter of 2021, as compared to $15.2 million for the first quarter of 2020. The increase in R&D expense for the first quarter of 2021 compared to the same period in the prior year was primarily due to higher R&D consulting expense, higher personnel expense, higher manufacturing expense primarily related to our PRX012 and birtamimab programs, higher clinical trial expense primarily related to birtamimab partially offset by lower PRX004 clinical trial expenses and higher collaboration expense with Roche related to the prasinezumab program. R&D expenses included non-cash share-based compensation expense of $2.0 million for the first quarter of 2021, as compared to $2.0 million for the first quarter of 2020. General and administrative (G&A) expenses totaled $11.1 million for the first quarter of 2021, as compared to $9.7 million for the first quarter of 2020. The increase in G&A expenses for the first quarter of 2021 compared to the same period in the prior year was primarily related to higher personnel expense and higher expense for our directors and officers insurance premium. G&A expenses included non-cash share-based compensation expense of $4.2 million for the first quarter of 2021, as compared to $3.5 million for the first quarter of 2020. Total non-cash share-based compensation expense was $6.2 million for the first quarter of 2021, as compared to $5.5 million for the first quarter of 2020. As of March 31, 2021, Prothena had $345.7 million in cash, cash equivalents and restricted cash (does not include the $60 million milestone earned in the second quarter from Roche) and no debt. As of May 4, 2021, Prothena had approximately 44.2 million ordinary shares outstanding. The Company continues to expect the full year 2021 net cash used in operating and investing activities to be $51 to $74 million, which includes receiving the $60 million milestone earned in the second quarter from Roche. The Company is updating its projected year end cash balance to approximately $316 million in cash, cash equivalents and restricted cash (midpoint) (versus prior guidance of $235 million) to include an additional $81 million in net proceeds primarily from the public offering in March. The estimated full year 2021 net cash used in operating and investing activities is primarily driven by an estimated net loss of $79 to $111 million, which includes an estimated $20 million of non-cash share-based compensation expense.
