aTyr Pharma Announces First Quarter 2019 Results and Provides Corporate Update

Phase 1b/2a proof-of-concept clinical trial of ATYR1923 in pulmonary sarcoidosis patients ongoing

Advanced lead position in Neuropilin-2 (NRP-2) biology with inaugural NRP-2 summit

Company to host conference call and webcast today at 5:00pm EDT / 2:00 PDT

SAN DIEGO – May 13, 2019 – aTyr Pharma, Inc. (Nasdaq: LIFE), a biotherapeutics company engaged in the discovery and development of innovative medicines based on novel immunological pathways, today announced first quarter 2019 results and provided a corporate update.

“During the first quarter, we continued to execute on our Phase 1b/2a study of our lead therapeutic candidate, ATYR1923, a selective NRP-2 inhibitor, in patients with pulmonary sarcoidosis, and we look forward to reporting interim results in the fourth quarter of this year,” said Dr. Sanjay Shukla, President and Chief Executive Officer of aTyr. “At the same time, we continued to advance our understanding of the emerging role of NRP-2 in the modulation of immune responses. We recently held an inaugural summit meeting of leading experts in the field of NRP-2 biology to discuss the down-regulation of the innate and adaptive immune systems and potential clinical utility across a broad range of inflammatory disease states.”

First Quarter 2019 and Subsequent Period Highlights


Advanced its ongoing Phase 1b/2a clinical trial of ATYR1923 in pulmonary sarcoidosis patients, with interim data expected during the fourth quarter of this year.


Hosted an inaugural Neuropilin-2 (NRP-2) Summit Meeting featuring key researchers from the United States and Europe to discuss the most recent discoveries relating to the development of therapeutics directed to the NRP-2 co-receptor, and related signaling pathways.


Closed a $5 million registered direct investment led by Federated Kaufmann Small Cap Fund.


Announced a research collaboration and option agreement with global biotherapeutics leader CSL Behring to accelerate development of product candidates derived from up to four tRNA synthetases from aTyr’s preclinical pipeline.


Research Highlights


Announced an upcoming poster presentation at the American Thoracic Society 2019 International Conference, which is being held May 19-22 in Dallas. The poster will describe preclinical findings from a study of ATYR1923 in murine models of interstitial lung diseases (ILDs), including sclerodermatous chronic graft-versus-host disease (scl cGvHD), Saccharopolyspora rectivirgula-induced chronic hypersensitivity pneumonitis (CHP), propionibacterium acnes-induced pulmonary granulomatosis (sarcoidosis) and rheumatoid arthritis-associated interstitial lung disease (RA-ILD). ATYR1923 treatment significantly decreased both skin and lung fibrosis in the scl cGvHD model, and it also reduced lung protein levels of several fibrosis-related cytokines or chemokines in the highly inflammatory experimental CHP and sarcoidosis models.


Presented a poster at the 2019 American Association for Cancer Research (AACR) summarizing recent data from the Company’s collaboration and ongoing pilot study with the University of Nebraska Medical Center aimed at advancing NRP-2 biology and exploring potential therapeutic opportunities for ATYR1923. The pilot study was led by Dr. Kaustubh Datta, a recognized expert in the field of NRP-2 biology.


Presented preclinical data at Keystone Symposia 2019 Conference in February demonstrating, for the first time, ATYR1923’s ability to bind to NRP-2 and down-regulate myeloid cells, specifically neutrophils, during lung inflammation. These findings help support aTyr’s belief in the mechanism of action of ATYR1923 to suppress immune engagement in pulmonary sarcoidosis as well as other interstitial lung diseases.

First Quarter 2019 Financial Results and Cash Position

Research and development expenses were $3.3 million and $6.2 million for the three months ended March 31, 2019 and 2018, respectively. General and administrative expenses were $2.5 million and $4.1 million for the three months ended March 31, 2019 and 2018, respectively. The decreases for both research and development expenses and general and administrative expenses were primarily related to the Company’s corporate restructuring announced in May 2018, where aTyr announced its focused development efforts on the clinical advancement of ATYR1923 along with related reductions in headcount and personnel-related costs and other cost saving measures.

As of March 31, 2019, aTyr had $43.0 million in cash, cash equivalents and investments. Subsequent to the end of the quarter, the Company raised $5.0 million in gross proceeds through a registered direct investment led by Federated Kaufmann Small Cap Fund.

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 (HARS) 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 initiated a proof-of-concept Phase 1b/2a trial evaluating ATYR1923 in patients with pulmonary sarcoidosis in the fourth quarter of 2018. 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 (PK) profile of multiple doses of ATYR1923. For the Phase 1b/2a trial, aTyr is collaborating with the Foundation for Sarcoidosis Research (FSR), the nation’s leading nonprofit organization dedicated to finding a cure for sarcoidosis and improving care for sarcoidosis patients. Under the terms of the collaboration, FSR will assist with clinical trial site initiation and patient enrollment.
