SAN DIEGO, Jan. 13, 2022 (GLOBE NEWSWIRE) -- aTyr Pharma Inc. (Nasdaq: LIFE), a biotherapeutics company engaged in the discovery and development of innovative medicines based on novel biological pathways, today announced that the United States Adopted Names (USAN) Council and the World Health Organization’s (WHO) International Nonproprietary Name (INN) Expert Committee have selected the nonproprietary name efzofitimod for ATYR1923, a novel immunomodulator targeting neuropilin-2 (NRP2), in clinical development for pulmonary sarcoidosis, a major form of interstitial lung disease.
“aTyr is working to develop a new class of medicines based on extracellular tRNA synthetase biology, and the assignment of the nonproprietary name efzofitimod for ATYR1923 is an important step as we continue to advance this potentially disease-modifying immunomodulator to its next stage of development,” said Sanjay S. Shukla, M.D., M.S., President and Chief Executive Officer of aTyr. “Efzofitimod is engineered from a naturally occurring splice variant of histidyl-tRNA synthetase, which is enriched in lung tissue and we believe plays a role in the natural regulation of the immune system. By restoring immune balance through selective modulation of NRP2, efzofitimod is the first tRNA synthetase-derived and NRP2-targeting therapy to demonstrate clinical activity in patients. We look forward to initiating a registrational trial of efzofitimod in our lead indication, pulmonary sarcoidosis, this year.”
The USAN Council and WHO are responsible for selecting simple, informative and unique nonproprietary (generic) drug names. Going forward, aTyr will use efzofitimod in place of ATYR1923.
About Efzofitimod
aTyr is developing efzofitimod as a potential therapeutic for patients with severe inflammatory lung diseases. 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.
About aTyr
aTyr is a biotherapeutics company engaged in the discovery and development of innovative medicines based on novel biological pathways. 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 down-regulate immune engagement in inflammatory lung diseases.
