aTyr Pharma to Present Poster at the European Respiratory Society (ERS) International Congress 2022

Sep 1, 2022

SAN DIEGO, Sept. 01, 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 platform, today announced that the company will present a poster on Monday, September 5, 2022, from 8:30AM9:30AM CEST at the European Respiratory Society (ERS) International Congress 2022 in Barcelona, Spain. The corresponding abstract and e-poster are available on the conference website. The poster will be available on the aTyr website once presented.

The poster presents findings for a highly selective and sensitive antibody for the immunohistochemical (IHC) detection of neuropilin-2 (NRP2) protein in patient tissue samples. NRP2 is a cell surface receptor that has been identified as the binding partner for efzofitimod, a novel immunomodulator in clinical development for the potential treatment of pulmonary sarcoidosis and other forms of interstitial lung disease (ILD). The antibody was shown to be highly specific for NRP2 and was used to demonstrate a high level of NRP2 protein expression in granulomas of sarcoidosis patient lung and skin biopsy samples.

“This unique antibody developed by the aTyr research team and optimized for IHC in collaboration with the Muders lab provides a highly specific and sensitive detection method for NRP2 that will facilitate characterization of the target receptor for efzofitimod in patient tissue samples,” said Leslie A. Nangle, Ph.D., Vice President, Research at aTyr. “This may provide an extremely useful clinical tool, potentially aiding in patient selection or stratification, thereby enabling thoughtful understanding of NRP2 expression as it relates to relevant disease states, in sarcoidosis, other ILD, oncology and other indications in which this receptor plays a role.”

Details of the poster presentation are as follows:

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 is currently conducting EFZO-FIT™, a Phase 3 study of efzofitimod in pulmonary sarcoidosis patients.

About aTyr

aTyr is a biotherapeutics company engaged in the discovery and development of first-in-class medicines from its proprietary tRNA synthetase 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.
