Prothena Reports Fourth Quarter and Full Year 2017 Financial Results, and Provides Financial Guidance and R&D Update
DUBLIN, Ireland, Feb. 14, 2018 -- Prothena Corporation plc (NASDAQ:PRTA), a late-stage clinical biotechnology company focused on the discovery, development and commercialization of novel therapies in the neuroscience and orphan categories, today reported financial results for the fourth quarter and full year 2017. In addition, the Company provided 2018 financial guidance and an update on its R&D programs.
"In 2017, our team progressed our clinical stage development programs towards key milestones, unveiled novel discovery programs, and continued to build our organization to support our maturing pipeline," said Gene Kinney, Ph.D., President and Chief Executive Officer of Prothena. "We successfully completed enrollment in both the Phase 2b PRONTO and Phase 3 VITAL studies in AL Amyloidosis. We also presented data elucidating the toxic effect - that is unique from other forms of heart failure - of misfolded soluble light chain on cardiomyocytes that results in increased production of NT-proBNP, a cardiac biomarker that has been shown in multiple independent studies to predict survival in patients with AL amyloidosis. We also initiated, with our partners at Roche, the Phase 2 PASADENA study of PRX002/RG7935 in patients with early Parkinson's disease. Looking ahead, in 2018 we will continue to capitalize on our deep expertise in protein misfolding in seeking to advance a broad pipeline of disease-modifying therapeutics in the neurodegenerative and orphan disease categories, and we remain focused and on track to reach key milestones, including the topline data from the Phase 2b PRONTO study which is expected in the second quarter and the initiation of the Phase 1 multiple ascending dose study of PRX004 in patients with ATTR amyloidosis expected by mid-year."
Full Year 2017 and Recent Highlights:
NEOD001 is a monoclonal antibody for the potential treatment of AL amyloidosis:
demonstrated the relationship between misfolded soluble light chain toxicity to cardiomyocytes and production of NT-proBNP.
PRX002/RG7935 is a monoclonal antibody for the potential treatment of Parkinson's disease and related synucleinopathies, and is the primary focus of Prothena's worldwide collaboration with Roche:
PRX004 is a monoclonal antibody for the potential treatment of ATTR amyloidosis:

Upcoming Research and Development Milestones
Prothena's development pipeline includes three protein immunotherapy programs.
Fourth Quarter and Full Year of 2017 Financial Results and 2018 Financial Guidance
Prothena reported a net loss of $47.8 million and $153.2 million for the fourth quarter and full year of 2017, respectively, as compared to a net loss of $48.9 million and $160.1 million for the fourth quarter and full year of 2016, respectively. Net loss per share for the fourth quarter and full year of 2017 was $1.24 and $4.07, respectively, as compared to a net loss per share of $1.41 and $4.66 for the fourth quarter and full year of 2016, respectively.
Prothena reported total revenue of $0.2 million and $27.5 million for the fourth quarter and full year of 2017, respectively, as compared to total revenue of $0.2 million and $1.1 million for the fourth quarter and full year of 2016, respectively. The increase in revenue for the full year of 2017 was primarily due to achievement of a clinical milestone payment from Roche of $30.0 million, of which $26.6 million was recognized as collaboration revenue and $3.4 million was recognized as an offset to research and development expenses.
Research and development (R&D) expenses totaled $33.5 million and $134.5 million for the fourth quarter and full year of 2017, respectively, as compared to $39.8 million and $119.5 million for the fourth quarter and full year of 2016, respectively. The decrease in R&D expenses for the fourth quarter of 2017 compared to the same period in the prior year was primarily due to lower product manufacturing expenses and to a lesser extent lower clinical trial costs, which were partially offset by higher personnel costs, higher consulting expense, and higher expense associated with PRX002/RG7935. The increase in R&D expenses for the full year of 2017 compared to the same period in the prior year was primarily due to higher personnel costs, and to a lesser extent higher clinical trial costs associated primarily with the NEOD001 program, higher consulting expenses and higher expenses associated with PRX002/RG7935, which were partially offset by a decrease in external expenses related to product manufacturing. R&D expenses included non-cash share-based compensation expense of $3.1 million and $10.9 million for the fourth quarter and full year of 2017, respectively, as compared to $1.9 million and $7.1 million for the fourth quarter and full year of 2016, respectively.
General and administrative (G&A) expenses totaled $14.0 million and $48.2 million for the fourth quarter and full year of 2017, respectively, as compared to $9.6 million and $41.1 million for the fourth quarter and full year of 2016, respectively. The increase in G&A expenses for the fourth quarter and full year of 2017 compared to the same periods in the prior year was primarily due to higher personnel costs and to a lesser extent higher consulting expense and other expenses in 2017, which were partially offset by a reduction in share-based compensation expense related to the accelerated vesting of stock options in the comparable periods in the prior year. Additionally, a gain was recognized from the assignment of the Company's former South San Francisco facility lease in January 2017. G&A expenses included non-cash share-based compensation expense of $4.4 million and $15.9 million in the fourth quarter and full year of 2017, respectively, as compared to $3.3 million and $17.8 million in the fourth quarter and full year of 2016, respectively.
Total non-cash share-based compensation expense was $7.4 million and $26.8 million for the fourth quarter and full year of 2017, respectively, as compared to $5.2 million and $24.9 million for the fourth quarter and full year of 2016, respectively.
As of December 31, 2017, Prothena had $421.7 million in cash, cash equivalents and restricted cash and no debt.
As of February 9, 2018, Prothena had approximately 38.5 million ordinary shares outstanding.
The Company expects the full year 2018 net cash burn from operating and investing activities to be $175 to $230 million, and to end the year with approximately $218 million in cash (mid-point). The estimated full year 2018 net cash burn from operating and investing activities is primarily driven by an estimated net loss of $200 to $260 million, which includes an estimated $33 million of non-cash share-based compensation expense.
