Prothena Reports First Quarter 2020 Financial Results and Provides R&D Update and Updated Financial Guidance

  • Net cash used in operating and investing activities was $23.2 million in the first quarter; quarter-end cash and restricted cash position of $355.4 million provides funding to advance a broad pipeline

DUBLIN, Ireland, May 06, 2020 (GLOBE NEWSWIRE) -- Prothena Corporation plc (PRTA), a clinical-stage neuroscience company with expertise in protein misfolding, today reported financial results for the first quarter of 2020. In addition, the Company provided an update on its R&D programs and 2020 financial guidance.

“While the COVID-19 pandemic has brought significant challenges to people around the world and to our industry, Prothena has acted to protect the health of patients and our employees and the continuity of our programs,” said Gene Kinney, Ph.D., President and Chief Executive Officer of Prothena. “The situation is fluid and continues to evolve and as such we have identified potential disruptions and activated mitigation plans designed to advance our programs even under these challenging circumstances. Our team continues to manage critical activities, exhibiting extraordinary resilience, focus and commitment to advancing our pipeline of novel therapeutics for devastating diseases. We were fortunate that COVID-19 related disruptions began after patients in the Phase 2 prasinezumab study (PASADENA) and the Phase 1 PRX004 study had completed assessments that comprise the primary objective in each study.”

First Quarter 2020 and Recent Developments

  • The Company continues to monitor the potential impacts of the COVID-19 pandemic to its business. Adaptations to the work environment have been implemented and the Company’s laboratories have remained productive. The known and potential impact to active clinical studies is described in more detail below. Prothena has drug supply for its ongoing studies and currently does not expect delays to its programs due to manufacturing or supply chain issues.

  • As part of Roche’s first quarter earnings announcement, an update was provided on Part 1 of the Phase 2 PASADENA study of prasinezumab in patients with early Parkinson’s disease. As updated by Roche, the study did not meet the primary objective, but showed signals of efficacy. These signals were observed on multiple prespecified secondary and exploratory clinical endpoints. Roche has begun further clinical development planning activities and is evaluating the data from Part 1 of the PASADENA study to determine next steps. Based on ongoing evaluation of the data, including potential discussions with health authorities, a further update on prasinezumab is expected later this year.

  • In a virtual oral presentation at the Advances in Alzheimer’s and Parkinson’s Therapies AAT-AD/PD Focus Meeting (AAT-AD/PD), Roche presented baseline data from the Phase 2 PASADENA study of prasinezumab in patients with early Parkinson's disease. The presentation, titled A Phase 2 study to evaluate the safety and efficacy of prasinezumab in early Parkinson's disease (PASADENA): rationale, design and baseline data is posted on www.prothena.com here. The presentation noted that the PASADENA study population can be considered representative of a wider Parkinson’s disease population, such as the one studied in the Parkinson's Progression Markers Initiative (PPMI) and is therefore suitable for testing the potential beneficial effect of drugs acting on disease progression, such as prasinezumab.

  • The Company appointed Brandon Smith as Chief Business Officer to lead Prothena’s business development initiatives, portfolio strategic planning and alliance management activities. Mr. Smith has extensive corporate, business development and operational expertise, and has held a number of executive roles at biotechnology companies.

Research and Development Updates and Upcoming Milestones

Prasinezumab (PRX002/RG7935), a potential treatment for Parkinson’s disease, is a monoclonal antibody designed to target alpha-synuclein and is the focus of the worldwide collaboration with Roche

  • Part 1 of the Phase 2 PASADENA study in patients with early Parkinson’s disease (N=316) being conducted by Roche is complete. Based on ongoing evaluation of Part 1 PASADENA study data, including potential discussions with health authorities, a further update on prasinezumab is expected later this year.

  • The 52-week blinded extension of the study (Part 2 of the Phase 2 PASADENA Study) is ongoing. Due to the COVID-19 pandemic, patients have missed assessments in Part 2 of the study. The full extent of the COVID-19 disruption to Part 2 is not yet known.

PRX004, a potential treatment for ATTR amyloidosis, is a monoclonal antibody designed to deplete the pathogenic, non-native forms of the TTR protein

  • The Phase 1 study of PRX004 is fully enrolled and as of early March patients in all 6 cohorts had received the three infusions and assessments that comprise the dose-escalation portion of the study. Interim data from cohorts 1 through 5 was reported in December.

  • At the conclusion of the dose-escalation portion of the study, patients meeting eligibility requirements were provided the option to enroll in the long-term-extension (LTE) portion of the study, which allows for up to 15 additional infusions per patient and is designed to further assess safety, tolerability, pharmacokinetics and pharmacodynamics of PRX004. The LTE also includes certain clinical outcome measures for patients in cohorts 4 through 6 at the month 10 assessment (prior to infusion) and at the end of study (month 19 assessment). As of early April, patients in cohorts 1 through 5 in the LTE had completed at least their month 12 assessment and one patient in cohort 6 had completed their month 10 assessment.

  • Because of the disruptions caused by the COVID-19 pandemic, some patients have had to discontinue from the study and most patients in the LTE portion of the study have missed at least one infusion and/or assessment. The Company continues to monitor the impact that COVID-19 will have on the LTE portion of the study based on the fluid circumstances at each of the sites in the United States and Europe. If the COVID-19 pandemic results in missed visits over a prolonged period, it is possible that more patients may not be able to complete the LTE portion of the study.

  • The Company believes the study has advanced sufficiently to determine next steps for the program and has begun further clinical development planning activities. The Company currently expects additional data from the dose-escalation and LTE portions of the study, as well as an update on next steps for clinical development, to be reported later this year. This timing, however, is dependent on any additional impacts of COVID-19.

Discovery and Preclinical Development: Prothena is advancing an early-stage pipeline of programs for a number of potential neurological indications

  • The Company continues to expect to advance IND-enabling activities in 2020 for our preclinical tau program, part of a global neuroscience collaboration with Bristol-Myers Squibb

  • The Company continues to expect to initiate IND-enabling activities in 2020 for our preclinical Aβ program

First Quarter 2020 Financial Results and Updated 2020 Financial Guidance

For the first quarter of 2020, Prothena reported a net loss of $23.6 million, as compared to a net loss of $20.9 million for the first quarter of 2019, which included a restructuring credit of $0.1 million in the first quarter of 2019 resulting from an adjustment in previously recorded employee termination benefits associated with the discontinuation of the NEOD001 program. Net loss per share for the first quarter of 2020 was $0.59, as compared to a net loss per share of $0.52 for the first quarter of 2019.

Prothena reported total revenue, all from its collaboration with Roche, of $0.1 million for the first quarter of 2020, as compared to total revenue of $0.2 million for the first quarter of 2019.

Research and development (R&D) expenses totaled $15.2 million for the first quarter of 2020, as compared to $13.3 million for the first quarter of 2019. The increase in R&D expense for the first quarter of 2020 compared to the same period in the prior year was primarily due to higher collaboration expense with Roche, higher manufacturing costs (primarily related to the tau and Aβ programs) and higher clinical trial costs (primarily associated with the PRX004 program). R&D expenses included non-cash share-based compensation expense of $2.0 million for the first quarter of 2020, as compared to $2.1 million for the first quarter of 2019.

General and administrative (G&A) expenses totaled $9.7 million for the first quarter of 2020, as compared to $9.9 million for first quarter of 2019. G&A expenses for the first quarter of 2020 decreased compared to the same period in the prior year primarily related to lower personnel costs (including share-based compensation expense), and lower legal and accounting fees, which was offset in part by higher costs for our director and officer insurance premiums. G&A expenses included non-cash share-based compensation expense of $3.5 million for the first quarter of 2020, as compared to $4.1 million for the first quarter of 2019.

Total non-cash share-based compensation expense was $5.5 million for the first quarter of 2020, as compared to $6.2 million for the first quarter of 2019.

As of March 31, 2020, Prothena had $355.4 million in cash, cash equivalents and restricted cash and no debt.

As of May 1, 2020, Prothena had approximately 39.9 million ordinary shares outstanding.

The Company is updating its projected full year 2020 net cash burn from operating and investing activities, and expects it to be $75 to $85 million (versus prior guidance of $60 to $76 million), and expects to end the year with approximately $299 million (midpoint) in cash, cash equivalents and restricted cash (cash position), representing a decrease of $11 million from prior guidance of $310 million (midpoint). This decrease in cash position is primarily driven by an increase in expenses related to further clinical development, planning activities and ongoing evaluation of data from the Phase 2 PASADENA study of prasinezumab, and is based on Prothena’s 30% portion of the U.S. co-development expenses. The updated estimated full year 2020 net cash burn from operating and investing activities is primarily driven by an updated estimated net loss of $101 to $118 million (versus prior guidance of $84 to $106 million), which includes an estimated $23 million of non-cash share-based compensation expense.
