“These findings further demonstrate the unique way in which efzofitimod is modulating myeloid cells to confer the anti-inflammatory benefits we have seen in patients with pulmonary sarcoidosis, a major form of interstitial lung disease (ILD),” said Sanjay S. Shukla, M.D., M.S., President and Chief Executive Officer of aTyr. “With an enhanced understanding of efzofitimod’s novel mechanism we have greater confidence in the potential for this first-in-class immunomodulator to be a transformative treatment for ILD, including pulmonary sarcoidosis, where we are currently conducting a pivotal Phase 3 study.”
Details of the presentation appears below. The poster will be available on the aTyr website once presented.
Title: Efzofitimod is an Immunomodulator of Myeloid Cell Function and Novel Therapeutic Candidate for Interstitial Lung Diseases
Session Title: Evaluating the Intersection Between Autoimmunity, Immunodeficiency, and Interstitial Lung Diseases
Session Format: Poster Discussion Session
Poster Number: 8837
Date and Time: Sunday, May 19, 2024, from 2:15 p.m. to 4:15 p.m.
Location: Room 31A-C (Upper Level), San Diego Convention Center
The poster presents findings demonstrating that by selectively binding neuropilin-2 (NRP2), a cell surface receptor upregulated at active sites of inflammation, most notably on myeloid cells, efzofitimod modulates the differentiation of monocyte-derived macrophages in healthy donors and ILD patients, resulting in a unique phenotype with reduced inflammatory potential. Additionally, the data further validates the discovery of NRP2 as an important new immune target, with higher expression of NRP2 detected on circulating monocytes from ILD patients compared to healthy donors and on macrophages within pulmonary sarcoidosis granulomas and other tissues from chronic inflammatory diseases. These findings suggest that efzofitimod may have broad therapeutic potential in diseases where myeloid cells play a central role in pathology, including ILD.
About Efzofitimod
Efzofitimod is a first-in-class biologic immunomodulator in clinical development for the treatment of interstitial lung disease (ILD), a group of immune-mediated disorders that can cause inflammation and fibrosis, or scarring, of the lungs. Efzofitimod is a tRNA synthetase derived therapy that selectively modulates activated myeloid cells through neuropilin-2 to resolve inflammation without immune suppression and potentially prevent the progression of fibrosis. aTyr is currently investigating efzofitimod in the global Phase 3 EFZO-FIT™ study in patients with pulmonary sarcoidosis, a major form of ILD, and in the Phase 2 EFZO-CONNECT™ study in patients with systemic sclerosis (SSc, or scleroderma)-related ILD. These forms of ILD have limited therapeutic options and there is a need for safer and more effective, disease-modifying treatments that improve outcomes.
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.
