aTyr Pharma to Present Findings from its tRNA Synthetase Platform at the International 28th tRNA Conference

Jun 13, 2022
Conference hosted by The Ohio State University’s Center for RNA Biology to showcase latest advancements in tRNA biology

 SAN DIEGO, June 13, 2022 (GLOBE NEWSWIRE) -- aTyr Pharma, Inc. (Nasdaq: LIFE), a biotherapeutics company engaged in the discovery and development of first-in-class medicines from its proprietary tRNA synthetase biology platform, today announced that Leslie A. Nangle, Ph.D., Vice President, Research at aTyr, will present at the International 28th tRNA Conference, which is scheduled to take place June 12 – 16, 2022, at The Ohio State University in Columbus, OH.

Extracellular tRNA synthetases represent a class of proteins that may play important roles in regulating cellular responses to certain disease states, in particular, cellular stress and imbalances in tissue homeostasis. aTyr is focused on elucidating novel pathways mediated through extracellular tRNA synthetases and creating new biologics to modulate these pathways, by either developing protein therapies based on extracellular tRNA synthetase fragments or generating monoclonal antibodies to target the pathway.

Dr. Nangle will participate in a panel with other tRNA focused companies to discuss emerging opportunities in tRNA therapeutics. Additionally, she will present on aTyr’s tRNA synthetase platform, including clinical proof-of-concept data from its lead tRNA synthetase derived candidate efzofitimod, which is entering Phase 3 clinical development for the treatment of pulmonary sarcoidosis, a major form of interstitial lung disease.

Details of the panel and presentation appear below.

Title: Emerging Opportunities in tRNA Therapeutics
Panelist: Leslie A. Nangle, aTyr Pharma
Date: Monday, June 13, 2022

Time: 4:45PM6:15PM EDT

Title: Efzofitimod, a Novel Therapeutic Based on Histidyl-tRNA Synthetase for Treatment of Interstitial Lung Diseases Presenter: Leslie A. Nangle, aTyr Pharma
Date: Thursday, June 16, 2022
Time: 1:20PM1:40PM EDT

“I am delighted to participate in this conference to showcase the pioneering work that aTyr has accomplished in the area of tRNA biology,” said Dr. Nangle. “Notably, I am pleased to present the progress we have made in advancing the first tRNA synthetase derived candidate, efzofitimod, from discovery to clinical proof-of-concept. Recent signals of efficacy in pulmonary sarcoidosis shown by efzofitimod, which is derived from a fragment of histidyl-tRNA synthetase (HARS), support the concept that modulating extracellular tRNA synthetase pathways has disease modifying therapeutic potential. These findings validate our platform as one that can generate new therapeutic candidates, not only from HARS but potentially from fragments derived from the additional 19 tRNA synthetase gene families covered by our intellectual property portfolio, potentially representing a new class of medicines.”

About Efzofitimod

aTyr is developing efzofitimod as a potential therapeutic for patients with fibrotic lung disease. Efzofitimod, 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 innate and adaptive immune response in inflammatory disease states. aTyr’s lead indication for efzofitimod is pulmonary sarcoidosis, a major form of interstitial lung disease. Clinical proof-of-concept for efzofitimod was recently established in a Phase 1b/2a multiple-ascending dose, placebo-controlled study of efzofitimod in patients with pulmonary sarcoidosis, which demonstrated safety and a consistent dose response and trends of benefit of efzofitimod compared to placebo on key efficacy endpoints, including steroid reduction, lung function, clinical symptoms and inflammatory biomarkers. aTyr intends to initiate EFZO-FIT, a Phase 3 study of efzofitimod in pulmonary sarcoidosis patients, in the third quarter of 2022.

About aTyr

aTyr is a biotherapeutics company engaged in the discovery and development of first-in-class medicines from its proprietary tRNA synthetase biology platform. aTyr’s research and development efforts are concentrated on a newly discovered area of biology, the extracellular functionality and signaling pathways of tRNA synthetases. aTyr has built a global intellectual property estate directed to a potential pipeline of protein compositions derived from 20 tRNA synthetase genes and their extracellular targets. aTyr’s primary focus is efzofitimod, a clinical-stage product candidate which binds to the neuropilin-2 receptor and is designed to downregulate immune engagement in fibrotic lung disease.
