Prothena Reports First Quarter 2019 Financial Results and Provides R&D Update
Net cash used in operating and investing activities was $17.6 million in the first quarter; quarter-end cash and restricted cash position of $414.2 million provides funding to advance neuroscience pipeline
Initiated cell line development of a lead candidate for preclinical tau program
DUBLIN, Ireland, May 7, 2019 -- Prothena Corporation plc (NASDAQ:PRTA), a clinical-stage neuroscience company, today reported financial results for the first quarter of 2019. In addition, the Company provided an update on its R&D programs and 2019 financial guidance.
“We continue to advance our neuroscience pipeline of investigational therapies, and are progressing several programs towards key milestones,” said Gene Kinney, Ph.D., President and Chief Executive Officer of Prothena. “We have initiated cell line development of a lead candidate for our tau program under our collaboration with Celgene. Enrollment in our Phase
1 study of PRX004 in ATTR amyloidosis is progressing and we now anticipate that the fourth quarter update on this program will include data from cohorts 1 through 4. Data from Part 1 of the Phase 2 PASADENA study of prasinezumab in Parkinson’s disease, which is being run by Roche, are expected in 2020. We also recently reported results from the Phase 3 VITAL study of NEOD001 in AL amyloidosis and are exploring business development opportunities that could result in further clinical investigation of NEOD001.”
First Quarter 2019 and Recent Development
NEOD001 (birtamimab) is an investigational humanized immunoglobulin G1 designed to directly neutralize soluble toxic aggregates and promote clearance of amyloid via phagocytosis to remove organ-deposited amyloid thought to cause organ dysfunction in patients with AL amyloidosis.
Reported results from the Phase 3 VITAL Amyloidosis Study of NEOD001 (birtamimab) in newly diagnosed, treatment naïve patients with AL amyloidosis and cardiac dysfunction (N=260), which was discontinued in 2018. The final hazard ratio (HR) for the composite primary endpoint (time to all-cause mortality or time to cardiac hospitalization more than 90 days after first infusion of study drug) of 0.835 (95% CI: 0.5799, 1.2011; p=0.330) was consistent with the futility analysis reported in April 2018. Post hoc analyses of all-cause mortality revealed a potential survival benefit favoring NEOD001 in the category of patients at highest risk for early mortality (Mayo Stage IV, n=77) with a HR of 0.544 (95% CI: 0.2738, 1.0826; p=0.0787). This potential survival benefit was more pronounced in Mayo Stage IV patients during the initial 12 months of treatment, with a HR of 0.498 (95% CI: 0.2404, 1.0304; p=0.0556).
Upcoming Research and Development Milestones
Prothena is advancing a pipeline of therapeutic candidates for a number of indications and novel targets.
Prasinezumab (PRX002/RG7935), a potential treatment for Parkinson’s disease, is a monoclonal antibody designed to target alpha-synuclein and is the focus of a worldwide collaboration with Roche.
The Phase 2 PASADENA study in patients with early Parkinson’s disease (N=316) is being conducted by Roche and data from Part 1 of this study are expected in 2020
PRX004, a potential treatment for ATTR amyloidosis, is a monoclonal antibody designed to target and clear the pathogenic, misfolded forms of the TTR protein.
The Phase 1 study of PRX004 continues to enroll patients with hATTR amyloidosis, and preliminary data from the first four of six dose level cohorts (0.1mg/kg, 0.3 mg/kg,1.0 mg/kg, 3.0 mg/kg, 10.0 mg/kg and 30.0 mg/kg), including safety, tolerability and pharmacodynamics, are expected in the fourth quarter of 2019
Tau is a protein implicated in diseases including Alzheimer's disease (AD), progressive supranuclear palsy (PSP), frontotemporal dementia (FTD) and chronic traumatic encephalopathy (CTE). Prothena’s internally discovered tau antibody targets a novel epitope on the protein.
The preclinical tau program, part of a worldwide collaboration with Celgene, initiated cell line development of a lead candidate
First Quarter 2019 Financial Results and Updated 2019 Guidance
Prothena reported a net loss of $20.9 million for the first quarter of 2019, as compared to a net loss of $48.7 million for the first quarter of 2018. Net loss per share for the first quarter of 2019 was $0.52, as compared to a net loss per share of $1.26 for the first quarter of 2018.
Prothena reported total revenue from its collaboration with Roche of $0.2 million for the first quarter of 2019 as compared to total revenue of $0.2 million for the first quarter of 2018.
Research and development (R&D) expenses totaled $13.3 million for the first of 2019, as compared to $34.7 million for the first quarter 2018. The decrease in R&D expenses compared to the first quarter of 2018 was primarily due to lower clinical trial costs, lower consulting and personnel costs and lower product manufacturing expenses. R&D expenses included non-cash share-based compensation expense of $2.1 million for the first quarter 2019 as compared to $2.3 million for the first quarter of 2018.
General and administrative (G&A) expenses totaled $9.9 million for the first quarter of 2019, as compared to $14.2 million for the first quarter of 2018. The decrease in G&A expenses compared to the first quarter of 2018 was primarily due to lower personnel costs and consulting expenses. G&A expenses included non-cash share-based compensation expense of $4.1 million for the first quarter of 2019, as compared to $4.6 million for the first quarter of 2018.
Total non-cash share-based compensation expense was $6.2 million for the first quarter of 2019, as compared to $6.9 million for the first quarter 2018.
As of March 31, 2019, Prothena had $414.2 million in cash, cash equivalents and restricted cash and no debt.
As of April 30, 2019, Prothena had approximately 39.9 million ordinary shares outstanding.
The Company is updating its full year 2019 net cash burn from operating and investing activities, and expects it to be $57-65 million, representing a decrease of approximately $7 million, and expects to end the year with approximately $371 million in cash, cash equivalents and restricted cash (midpoint). The Company had planned on initiating cell line development of a lead candidate for an Amyloid beta discovery program this year but will not be making additional investments in this program at this time based on the recent discontinuation of Biogen’s aducanumab program. The updated estimated full year 2019 cash burn from operating and investing activities is primarily driven by an updated estimated net loss of $83-94 million, which includes an estimated $24 million of non-cash shared-based compensation expense.
Prothena Corporation plc is a clinical-stage neuroscience company focused on the discovery and development of novel therapies with the potential to fundamentally change the course of progressive, life-threatening diseases. Fueled by its deep scientific understanding built over decades of neuroscience research, Prothena is advancing a pipeline of therapeutic candidates for a number of indications and novel targets including Parkinson’s disease and other related synucleinopathies (prasinezumab - PRX002/RG7935) and ATTR amyloidosis (PRX004), as well as tau and TDP-43 where its scientific understanding of disease pathology can be leveraged.
