• Phase 3 EFZO-FIT™ study of efzofitimod in pulmonary sarcoidosis expected to complete enrollment in the second quarter of 2024.
  
• Ended the first quarter 2024 with $87.7 million in cash, cash equivalents, restricted cash and investments.

SAN DIEGO, May 02, 2024 (GLOBE NEWSWIRE) -- aTyr Pharma, Inc. (Nasdaq: LIFE) (“aTyr” or the “Company”), a clinical stage biotechnology company engaged in the discovery and development of first-in-class medicines from its proprietary tRNA synthetase platform, today announced first quarter 2024 results and provided a corporate update. 

“During the first quarter of 2024 we continued to execute on our two clinical studies for our lead therapeutic candidate, efzofitimod, in interstitial lung disease (ILD),” said Sanjay S. Shukla, M.D., M.S., President and Chief Executive Officer of aTyr. “We are pleased with the study conduct and quality to date for our global pivotal Phase 3 EFZO-FIT™ study in patients with pulmonary sarcoidosis, a major form of ILD with high unmet medical need, and we look forward to completing enrollment in this study, which is anticipated this quarter.”

First Quarter 2024 and Subsequent Period Highlights

• Continued enrollment in the global pivotal Phase 3 EFZO-FIT™ study to evaluate the efficacy and safety of efzofitimod in patients with pulmonary sarcoidosis. This is a randomized, double-blind, placebo-controlled, 52-week study consisting of three parallel cohorts randomized equally to either 3.0 mg/kg or 5.0 mg/kg of efzofitimod or placebo dosed intravenously monthly for a total of 12 doses. The study intends to enroll up to 264 patients with pulmonary sarcoidosis. The study is currently enrolling at more than 90 centers in 9 countries. Based on current enrollment projections, the Company anticipates completing enrollment in the study in the second quarter of 2024. Patients who complete the study and wish to receive treatment with efzofitimod outside of the clinical trial are eligible to participate in an Individual Patient Expanded Access Program (EAP).
• Continued enrollment in the Phase 2 EFZO-CONNECT™ study to evaluate the efficacy, safety and tolerability of efzofitimod in patients with SSc-ILD. This proof-of-concept study is a randomized, double-blind, placebo-controlled, 28-week study consisting of three parallel cohorts randomized 2:2:1 to either 270 mg or 450 mg of efzofitimod or placebo dosed intravenously monthly for a total of 6 doses. The study intends to enroll up to 25 patients with SSc-ILD and is open for enrollment at multiple centers in the U.S.
• Presented a poster on ATYR0750 at the Gordon Research Conference Fibroblast Growth Factors in Development and Disease. The poster demonstrated that the alanyl-tRNA synthetase fragment that forms ATYR0750 binds selectively to FGFR4 and induces morphological changes and downstream signaling in liver cells with functional similarities to FGF2.
• Poster for efzofitimod to be presented at the upcoming American Thoracic Society (ATS) 2024 International Conference. The conference is scheduled to take place May 17 – 22, 2024, in San Diego, CA.
  • Poster 8837 – Efzofitimod is an Immunomodulator of Myeloid Cell Function and Novel Therapeutic Candidate for Interstitial Lung Diseases on Sunday, May 19, 2024, at 2:15 p.m. PDT.

First Quarter 2024 Financial Highlights and Cash Position

• Cash & Investment Position: Cash, cash equivalents, restricted cash and investments as of March 31, 2024, were $87.7 million. Based on the Company’s current operational plans and existing cash, the Company maintains its prior guidance and believes its cash runway will be sufficient to fund the Company’s operations through the filing of a Biologics License Application (BLA) for efzofitimod in pulmonary sarcoidosis.
• R&D Expenses: Research and development expenses were $13.4 million for the first quarter 2024, which consisted primarily of clinical trial costs for the Phase 3 EFZO-FIT™ and Phase 2 EFZO-CONNECT™ studies, manufacturing costs for the efzofitimod program and research and development costs for the efzofitimod and discovery programs.
• G&A Expenses: General and administrative expenses were $3.5 million for the first quarter 2024.
• Collaboration and License Revenue: Collaboration and license revenue related to the Kyorin Agreement was $0.2 million for the first quarter of 2024, which consisted of drug product material sold to Kyorin for the Japan portion of the EFZO-FIT™ study.

About Efzofitimod

Efzofitimod is a first-in-class biologic immunomodulator in clinical development for the treatment of interstitial lung disease (ILD), a group of immune-mediated disorders that can cause inflammation and fibrosis, or scarring, of the lungs. Efzofitimod is a tRNA synthetase derived therapy that selectively modulates activated myeloid cells through neuropilin-2 to resolve inflammation without immune suppression and potentially prevent the progression of fibrosis. aTyr is currently investigating efzofitimod in the global Phase 3 EFZO-FIT™ study in patients with pulmonary sarcoidosis, a major form of ILD, and in the Phase 2 EFZO-CONNECT™ study in patients with systemic sclerosis (SSc, or scleroderma)-related ILD. These forms of ILD have limited therapeutic options and there is a need for safer and more effective, disease-modifying treatments that improve outcomes.

About aTyr

aTyr is a clinical stage biotechnology company leveraging evolutionary intelligence to translate tRNA synthetase biology into new therapies for fibrosis and inflammation. tRNA synthetases are ancient, essential proteins that have evolved novel domains that regulate diverse pathways extracellularly in humans. aTyr’s discovery platform is focused on unlocking hidden therapeutic intervention points by uncovering signaling pathways driven by its proprietary library of domains derived from all 20 tRNA synthetases. aTyr’s lead therapeutic candidate is efzofitimod, a first-in-class biologic immunomodulator in clinical development for the treatment of interstitial lung disease, a group of immune-mediated disorders that can cause inflammation and progressive fibrosis, or scarring, of the lungs.
