Published results from the Phase 1b multiple ascending dose study of prasinezumab (PRX002/RG7935) in patients with Parkinson’s disease in JAMA Neurology

DUBLIN, Ireland - August 7, 2018 - Prothena Corporation plc (NASDAQ:PRTA), a clinical-stage neuroscience company, today reported financial results for the second quarter and first six months of 2018. In addition, the Company provided an update on its R&D programs.

“We are developing a broad and novel pipeline targeting devastating neurological diseases and steadily advancing both our proprietary programs as well as our collaboration programs with Roche and Celgene,” said Gene Kinney, PhD, President and Chief Executive Officer of Prothena. “Enrollment in the ongoing clinical studies of PRX004 and prasinezumab (PRX002/RG7935) is continuing and we expect initial data from these programs in 2019 and 2020, respectively. Additionally, we are advancing multiple discovery-stage programs towards the clinic with the potential to offer significant benefit to patients who suffer from neurological diseases with tremendous unmet medical need.”

Second Quarter 2018 and Recent Highlights:
Published results from the Phase 1b multiple ascending dose study of prasinezumab (PRX002/RG7935) in patients with Parkinson’s disease in JAMA Neurology. The paper is entitled “Safety and Tolerability of Multiple Ascending Doses of PRX002/RG7935, an Anti-α-Synuclein Monoclonal Antibody, in Patients With Parkinson Disease: A Randomized Clinical Trial.”
Appointed Tran B. Nguyen as Chief Operating Officer, in addition to his responsibilities as Chief Financial Officer. Mr. Nguyen had been Prothena’s Chief Financial Officer since 2013 and has more than 20 years of experience including strategic leadership positions in the biotech, banking and private equity industries.
Initiated a reorganization and updated financial guidance to align the Company’s resources on advancing its broad neuroscience pipeline.

Upcoming Research and Development Milestones

Prasinezumab (PRX002/RG7935)





The Phase 2 PASADENA study, which is being conducted by Roche and was initiated in the second quarter of 2017, continues to enroll patients with early Parkinson’s disease, and data from this study are expected in 2020
PRX004
The Phase 1 study of PRX004, initiated in the second quarter of 2018, continues to enroll patients with ATTR amyloidosis, and pharmacodynamic data from the lower doses of this study are expected in 2019
Discovery
The preclinical tau program (a worldwide collaboration with Celgene) is expected to initiate cell line development of a lead candidate in 2019
The preclinical Aβ (Amyloid beta) program is expected to initiate cell line development of a lead candidate in 2019

Second Quarter and First Six Months of 2018 Financial Results
For the second quarter and first six months of 2018, Prothena reported a net loss of $59.9 million and $108.6 million, respectively, which includes restructuring charges of $20.9 million associated with the discontinuation of the NEOD001 program, as compared to a net loss of $17.7 million and $53.1 million for the second quarter and first six months of 2017, respectively. Net loss per share for the second quarter and first six months of 2018 was $1.50 and $2.77, respectively, as compared to a net loss per share of $0.46 and $1.44 for the second quarter and first six months of 2017, respectively.

Prothena reported total revenue from its collaboration with Roche of $0.3 million and $0.5 million for the second quarter and first six months of 2018, respectively, as compared to total revenue of $26.8 million and $27.1 million for the second quarter and first six months of 2017, respectively.

Research and development (R&D) expenses totaled $31.5 million and $66.2 million for the second quarter and first six months of 2018, respectively, as compared to $34.0 million and $59.7 million for the second quarter and first six months of 2017, respectively. The decrease in R&D expenses for the second quarter 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, offset in part by higher expenses associated with prasinezumab (PRX002/RG7935). The increase in R&D expenses for the first six months compared to the same period in the prior year was primarily due to higher expenses associated with prasinezumab, higher consulting expenses and higher personnel costs, which were partially offset by lower product manufacturing expenses and to a lesser extent lower clinical trial costs. R&D expenses included non-cash share-based compensation expense of $2.6 million and $4.8 million for the second quarter and first six months of 2018, respectively, as compared to $2.7 million and $5.0 million for the second quarter and first six months of 2017, respectively.

General and administrative (G&A) expenses totaled $11.0 million and $25.2 million for the second quarter and first six months of 2018, respectively, as compared to $10.9 million and $21.7 million for second quarter and first six months of 2017, respectively. The increase in G&A expenses for the first six months compared to the same periods in the prior year was primarily due to higher personnel costs and to a lesser extent higher legal expenses. G&A expenses included non-cash share-based compensation expense of $3.8 million and $8.4 million for the second quarter and first six months of 2018, respectively, as compared to $3.9 million and $7.2 million for the second quarter and first six months of 2017, respectively.

Total non-cash share-based compensation expense was $8.8 million and $15.7 million for the second quarter and first six months of 2018, respectively, which included $2.5 million of non-cash share-based compensation





expense included in the restructuring costs, as compared to $6.7 million and $12.3 million for the second quarter and first six months of 2017, respectively.

As of June 30, 2018, Prothena had $490.3 million in cash, cash equivalents and restricted cash (including the $100 million upfront payment received from Celgene in April 2018) and no debt.

As of July 20, 2018, Prothena had approximately 39.8 million ordinary shares outstanding.

The Company expects its 2018 net cash burn from operating and investing activities to be $40 to $50 million, which includes $110 million of cash provided by operating activities associated with the Celgene collaboration, and to end the year with approximately $421 million in cash (mid-point). The estimated 2018 net cash burn from operating and investing activities is primarily driven by an estimated net loss of $170 to $185 million, which includes an estimated $25 million of non-cash share-based compensation expense. The estimated 2018 net loss includes $80 to $85 million of operating expenses associated with NEOD001 and the Company’s reorganization, including research, development, manufacturing and pre-commercial expenses, severance costs and contract termination fees related to manufacturing obligations and approximately $8 million of non-cash share-based compensation expense.
