aTyr Pharma has announced a significant publication in Science Translational Medicine validating the mechanism of action of efzofitimod, their lead therapeutic candidate. The research demonstrates efzofitimod's unique anti-inflammatory mechanism targeting macrophages through the neuropilin-2 (NRP2) receptor.
The publication details how efzofitimod, derived from histidyl-tRNA synthetase (HARS), binds specifically to NRP2, which is highly expressed in inflammatory sites. This binding inhibits pro-inflammatory receptors and cytokines, potentially disrupting chronic inflammation and fibrosis cycles.
Currently, efzofitimod is undergoing a global Phase 3 EFZO-FIT™ study for pulmonary sarcoidosis and a Phase 2 EFZO-CONNECT™ study for systemic sclerosis-related ILD. The drug has received orphan drug designation in the U.S., E.U., and Japan for sarcoidosis, and Fast Track designation in the U.S. for both pulmonary sarcoidosis and SSc-ILD.
aTyr Pharma announced a fourth positive safety review by an independent data and safety monitoring board (DSMB) for its Phase 3 EFZO-FIT™ study of efzofitimod in pulmonary sarcoidosis patients. The DSMB recommended continuing the study without modifications, reinforcing the therapeutic candidate's favorable safety profile.
The global Phase 3 study involves 268 subjects across multiple centers in the United States, Europe, Japan, and Brazil. The 52-week trial includes three parallel cohorts randomized to receive either 3.0 mg/kg or 5.0 mg/kg of efzofitimod or placebo, administered intravenously monthly for 12 doses. The study's primary endpoint focuses on steroid reduction, with secondary endpoints measuring lung function and sarcoidosis symptoms.

aTyr Pharma announced the presentation of two posters about their tRNA synthetase candidate ATYR0101 at the Keystone Symposia on Fibrosis. The research demonstrates that ATYR0101, a fusion protein derived from aspartyl-tRNA synthetase, binds to LTBP-1 to induce myofibroblast apoptosis, showing significant anti-fibrotic effects in lung and kidney fibrosis models.
The preclinical studies revealed that ATYR0101 reduced key fibrosis measures, including Ashcroft score and collagen content in the bleomycin model of lung fibrosis and the ureteral obstruction model of kidney fibrosis. The compound's mechanism of action differs from current standard treatments, suggesting potential as a novel therapeutic approach for advanced fibrotic conditions.
