aTyr is a clinical-stage biotechnology company focused on developing first-in-class medicines from its tRNA synthetase platform. Their lead candidate, efzofitimod, is being developed for the treatment of interstitial lung disease.
aTyr Pharma announced positive results from the third pre-planned interim safety analysis of its Phase 3 EFZO-FIT™ study for efzofitimod in pulmonary sarcoidosis patients. The independent Data and Safety Monitoring Board (DSMB) reviewed data from all 268 enrolled patients and recommended continuing the study without modifications.
The EFZO-FIT™ study is a global Phase 3 randomized, double-blind, placebo-controlled trial evaluating efzofitimod's efficacy and safety. The 52-week study includes three parallel cohorts randomized to receive either 3.0 mg/kg, 5.0 mg/kg of efzofitimod, or placebo monthly for 12 doses. The trial's primary endpoint is 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.
aTyr Pharma (Nasdaq: ATYR) announced it will present two posters about its tRNA synthetase candidate ATYR0101 at the Keystone Symposia on Fibrosis in Whistler, British Columbia, from December 8-11, 2024. The first poster explores how a newly evolved domain of Asp-tRNA Synthetase interacts with LTBP-1 to induce myofibroblast apoptosis. The second poster discusses anti-fibrotic activity observed in preclinical models of pulmonary and renal fibrosis. Both presentations are scheduled for Monday, December 9, 2024, at 7:30 p.m. PST during Poster Session #1.

Key findings include:
- 54.4% of patients in the subtherapeutic group relapsed following corticosteroid taper, compared to only 7.7% in the therapeutic group
- Median time-to-first-relapse in the subtherapeutic group was 126 days, while only one of 17 patients in the therapeutic group relapsed by the end of the study (p=0.017)
