aTyr Pharma Announces Fourth Quarter and Full Year 2019 Results and Provides Corporate Update

SAN DIEGO, March 26, 2020 (GLOBE NEWSWIRE) -- aTyr Pharma Inc. (Nasdaq: LIFE), a biotherapeutics company engaged in the discovery and development of innovative medicines based on novel immunological pathways, today announced fourth quarter and full year 2019 results and provided a corporate update.

“2019 was a productive year for aTyr and we achieved some key milestones, including the announcement of interim safety data results for our ongoing ATYR1923 Phase 1b/2a clinical trial for patients with pulmonary sarcoidosis. We also recently entered into a licensing collaboration with Kyorin Pharmaceutical Co., Ltd. (Kyorin) and received an $8.0 million upfront payment. Including our efforts related to neuropilin-2 (NRP2) receptor biology, we believe these milestones represent significant advancements of our pipeline” said Dr. Sanjay S. Shukla, M.D., M.S., president and chief executive officer of aTyr.

“As the COVID-19 pandemic continues to impact daily life, we remain committed to the safety of our employees as well as our physician partners and the patients who are participating in our ATYR1923 Phase 1b/2a clinical study. This global public health crisis has been challenging for clinical trial conduct worldwide, and we now anticipate there will be a delay in topline results from our study, which were previously anticipated in the third quarter of this year. We are working closely with our investigators to implement procedures which will allow for rapid completion of this study when the demand on the health system eases.”

“Importantly, the successful licensing deal and public offering that we completed in 2020, together with cash on hand, provide critical resources that we believe will comfortably allow us to reach significant and potentially value creating milestones. We remain committed to completion of our Phase 1b/2a study as expeditiously as possible as we work to introduce an entirely new class of therapeutics to treat unmet needs in interstitial lung diseases (ILDs).”

2019 and Subsequent Period Highlights and Upcoming Milestones

• Announced the results of a pre-planned, blinded interim analysis of safety and tolerability, the primary endpoint of its ongoing Phase 1b/2a clinical trial of its lead therapeutic candidate, ATYR1923, in patients with pulmonary sarcoidosis. Interim safety data results announced were from 15 pulmonary sarcoidosis patients who had received a minimum of one dose of blinded study drug (ATYR1923 or placebo). Study drug (ATYR1923 or placebo) was observed to be generally safe and well tolerated with no drug-related serious adverse events, consistent with our Phase 1 study results in healthy volunteers. Adverse events were mostly mild or moderate in severity and assessed by the study investigators as unrelated to study drug.
• Entered into a collaboration and license agreement with Kyorin for the development and commercialization of ATYR1923 for ILDs in Japan (the Kyorin Agreement). aTyr received an $8 million upfront payment and is eligible to receive up to an additional $167 million in the aggregate upon achievement of certain development, regulatory and sales milestones, as well as tiered royalties on net sales in Japan.
• Announced the appointment of Arthur M. Mercurio, Ph.D. as a scientific advisor to the company. aTyr’s abstract, “Domain-specific antibodies to Neuropilin-2 implicate VEGF-C and not Semaphorin 3F in breast cancer stem cell function” was accepted by the American Association for Cancer Research for a poster session at its Annual Meeting, and was completed in conjunction with Dr. Mercurio’s lab at the Department of Molecular, Cell and Cancer Biology at the University of Massachusetts Medical School.
• Published “Serum-circulating His-tRNA synthetase inhibits organ-targeted immune responses,” in the Nature journal Cellular and Molecular Immunology highlighting the essential role that histidyl tRNA synthetase (HARS) plays in the modulation of immune cell engagement in a broad range of disease states, including ILDs.
• Earlier this week, announced its Hong Kong subsidiary, Pangu BioPharma Limited (Pangu), together with the Hong Kong University of Science and Technology (HKUST), has been awarded a grant of approximately $750,000 to build a high-throughput platform for the development of bi-specific antibodies. This grant will help further support the company’s NRP2 antibody development program.
• Raised gross proceeds of $20.7 million through the issuance of 4,870,588 shares of common stock in early 2020 from a public offering of common stock and the full exercise of the underwriters’ over-allotment option.
• In March 2019, entered into a research and option agreement with global biotherapeutics leader CSL Behring to identify up to four new IND candidates from aTyr’s tRNA synthetase pipeline (the CSL Agreement). aTyr is eligible to receive $4.25 million per synthetase, or up to $17 million in potential total option fees from the collaboration if all four synthetase advance.

Fourth Quarter 2019 Financial Results

Total revenues were $0.1 million for the three months ended December 31, 2019, representing collaboration revenue from the CSL Agreement. Research and development expenses were consistent between quarters at $3.6 million and $3.5 million for the three months ended December 31, 2019 and 2018, respectively. General and administrative expenses were also consistent between quarters at $2.5 million and $2.4 million for the three months ended December 31, 2019 and 2018, respectively.

Year Ended December 31, 2019 Financial Results and Cash Position

Total revenues were $0.4 million for the year ended December 31, 2019, consisting of collaboration revenue from the CSL Agreement. Research and development expenses were $14.0 million and $20.4 million for the years ended December 31, 2019 and 2018, respectively. The decrease of $6.4 million was due primarily to a $2.8 million decrease in personnel associated costs mainly as a result of a reduction in force initiated in May 2018, a decrease of $1.7 million in costs associated with our research collaboration with The Scripps Research Institute which we terminated effective November 2018, a $1.7 million decrease in preclinical research and development expenses and a decrease of $0.7 million related to lower product manufacturing costs. The decrease was offset in part by an increase of $0.7 million related to our ATYR1923 Phase 1b/2a clinical trial.

General and administrative expenses were $9.4 million and $12.4 million for the years ended December 31, 2019 and 2018, respectively. The decrease of $3.0 million was due primarily to a $2.2 million decrease in personnel associated costs mainly as a result of the May 2018 reduction in force, and a $0.8 million decrease in professional fees.

As of December 31, 2019, aTyr had $31.1 million in cash, cash equivalents and investments. Subsequent to the end of the year, the company received an $8.0 million upfront payment in connection with the Kyorin Agreement and gross proceeds of $20.7 million from the public offering of common stock, resulting in an estimated $50 million in cash, cash equivalents and investments at the end of the first quarter of 2020. As of December 31, 2019, aTyr had $8.7 million in long-term loans. aTyr plans to retire its debt in November and anticipates exiting 2020 with over $20 million in cash, cash equivalents and investments.

About ATYR1923

aTyr is developing ATYR1923 as a potential therapeutic for patients with interstitial lung diseases. ATYR1923, a fusion protein comprised of the immuno-modulatory domain of histidyl tRNA synthetase fused to the FC region of a human antibody, is a selective modulator of neuropilin-2 that downregulates the innate and adaptive immune response in inflammatory disease states. aTyr is currently enrolling a proof-of-concept Phase 1b/2a trial evaluating ATYR1923 in patients with pulmonary sarcoidosis. This Phase 1b/2a study is a multi-ascending dose, placebo-controlled, first-in-patient study of ATYR1923 that has been designed to evaluate the safety, tolerability, steroid sparing effect, immunogenicity and pharmacokinetics profile of multiple doses of ATYR1923.

About NRP2

Neuropilin-2 (NRP2) is a cell surface receptor that plays a key role in lymphatic development and in regulating inflammatory responses. In many forms of cancer, high NRP2 expression is associated with worse outcomes. NRP2 can interact with multiple ligands and co-receptors through distinct domains to influence their functional roles, making it a potential drug target with multiple distinct therapeutic applications. NRP2 interacts with type 3 semaphorins and plexins to impact inflammation and with forms of vascular endothelial growth factor (VEGF) and their receptors, to impact lymphangiogenesis. In addition, NRP2 modulates interactions between CCL21 and CCR7 potentially impacting homing of dendritic cells to lymphoid organs. aTyr is currently investigating NRP2 receptor biology, both internally and in collaboration with key academic thought leaders, as a novel target for new product candidates for a variety of diseases, including cancer and inflammation.
