aTyr Pharma to Present Preclinical Research Demonstrating Anti-Fibrotic Effects of ATYR0101 in Lung and Kidney Fibrosis at Keystone Symposia on Fibrosis
LIFE 12.09.2024
Drug:DARS-ATYR0101 ATYR0101
Diseases:fibrosis
Date of Upcoming Event:2024-12-08
Name of Upcoming Event:Keystone Symposia on Fibrosis: Inflammation, Drivers, and Therapeutic Resolution
About Gravity Analytica
ATYR0101 is a fusion protein derived from a proprietary extracellular domain of aspartyl-tRNA synthetase (DARS) that binds to latent transforming growth factor beta binding protein 1 (LTBP-1) to induce myofibroblast apoptosis.
“We are excited by these findings that further demonstrate the way in which ATYR0101 binds a known fibrosis target with pronounced effects in preclinical models of lung and renal fibrosis,” said
Details of the presentations appear below. The posters will be available on the aTyr website once presented.
Title:A Newly Evolved Domainof Asp-tRNA Synthetase Interacts with Latent Transforming Growth Factor Beta Binding Protein 1 (LTBP-1) to Induce Myofibroblast ApoptosisAuthors:
The poster presents findings demonstrating that ATYR0101 binds directly to LTBP-1 resulting in caspase-3/7 mediated apoptosis in transforming growth factor beta (TGFβ)-1-differentiated myofibroblasts while having no effect on undifferentiated fibroblasts, which was observed in multiple cell types demonstrating potential in several organ systems. The ATYR0101-induced myofibroblast apoptosis activity was confirmed to be dependent upon LTBP-1, TGFβactivation and downstream gene expression changes. These findings suggest that ATYR0101 has promise as a novel and transformative anti-fibrotic therapeutic with a unique mechanism of action.
Title:Anti-FibroticActivity Observed Across Preclinical Models of Pulmonary and Renal Fibrosis for a Potential Therapeutic Based on Asp-tRNA SynthetaseAuthors:
The poster presents findings investigating ATYR0101 in the bleomycin (BLM) model of lung fibrosis and ureteral obstruction (UUO) model of kidney fibrosis to examine the pharmacological activity of ATYR0101 in experimental models of fibrotic disease. In the lung BLM model, ATYR0101 treatment resulted in a significant reduction in
About aTyr
aTyr is a clinical stage biotechnology company leveraging evolutionary intelligence to translate tRNA synthetase biology into new therapies for fibrosis and inflammation. tRNA synthetases are ancient, essential proteins that have evolved novel domains that regulate diverse pathways extracellularly in humans. aTyr’s discovery platform is focused on unlocking hidden therapeutic intervention points by uncovering signaling pathways driven by its proprietary library of domains derived from all 20 tRNA synthetases. aTyr’s lead therapeutic candidate is efzofitimod, a first-in-class biologic immunomodulator in clinical development for the treatment of interstitial lung disease, a group of immune-mediated disorders that can cause inflammation and progressive fibrosis, or scarring, of the lungs.

We intend these forward-looking statements to be covered by such safe harbor provisions for forward-looking statements and are making this statement for purposes of complying with those safe harbor provisions. These forward-looking statements include, among others, statements regarding the research and development activities related to and the potential therapeutic benefits and applications of our current and future product candidates, including ATYR0101 as a transformative, next generation anti-fibrotic differentiated from the current standard of care. These forward-looking statements also reflect our current views about our plans, intentions, expectations, strategies and prospects, which are based on the information currently available to us and on assumptions we have made. Although we believe that our plans, intentions, expectations, strategies and prospects, as reflected in or suggested by these forward-looking statements, are reasonable, we can give no assurance that the plans, intentions, expectations, strategies or prospects will be attained or achieved.
