aTyr Pharma Announces Expansion of Research Collaboration with The Ohio State University
aTyr Pharma, Inc. (Nasdaq: LIFE) has expanded its research collaboration with The Ohio State University to explore immune mechanisms and identify biomarkers of efficacy for its lead therapy, ATYR1923, targeting pulmonary sarcoidosis. Led by Dr. Elliott Crouser, the collaboration aims to analyze blood samples from sarcoidosis patients to understand granuloma formation and potentially improve treatment outcomes. Given that existing treatments offer limited efficacy, this study may significantly impact patient management. The findings from a related pilot study will be presented at the upcoming European Respiratory Society Congress.
- Expansion of collaboration with OSU enhances research on ATYR1923.
- Potential identification of biomarkers for patient selection and treatment response.
- The study builds on successful pilot findings accepted for presentation at an international congress.
- ATYR1923 shows promise in disrupting granuloma formation, addressing a significant medical need.
- None.
Collaboration led by Dr. Elliott Crouser to explore underlying cellular mechanisms of pulmonary sarcoidosis and identify potential sarcoidosis biomarkers.
SAN DIEGO, Aug. 10, 2021 (GLOBE NEWSWIRE) -- aTyr Pharma, Inc. (Nasdaq: LIFE), a clinical stage biotherapeutics company, today announced that the company has expanded its research collaboration with The Ohio State University (OSU) to deepen the understanding of the immune mechanisms of sarcoid granuloma formation and identify potential biomarkers of efficacy for the company’s lead therapeutic candidate, ATYR1923, which is currently in clinical development for the treatment of pulmonary sarcoidosis. The research will be conducted in the laboratory of Elliott Crouser, M.D., Professor of Pulmonology, Critical Care and Sleep Medicine at OSU. Dr. Crouser specializes in sarcoidosis research and treatment and will serve as the principal investigator.
The collaboration, which expands upon a successful pilot proof-of-concept study, will assess the effect of ATYR1923 on sarcoid granuloma formation in vitro in blood samples taken from sarcoidosis patients. The study will focus on identifying the relevant immune mechanisms triggered in granuloma formation and analyze promising biomarkers predictive of strong granuloma formation in order to assess whether they could be used as predictive biomarkers for treatment selection or treatment response to ATYR1923.
“We look forward to working with aTyr on this important initiative to expand the current understanding of the underlying mechanisms involved in pulmonary sarcoidosis, particularly the formation of granulomas. This work has the potential to identify promising biomarkers that may be used to predict treatment response, including to ATYR1923. Current treatment options for pulmonary sarcoidosis are limited, and the ability to determine a patient population that may benefit from a potential treatment such as ATYR1923 presents the opportunity to take a much-needed step forward in managing this disease,” said Dr. Crouser.
“We are very pleased to expand this research collaboration with OSU and Dr. Crouser. This collaboration will build upon the successful findings from research conducted with Dr. Crouser that were recently accepted to be presented at the upcoming European Respiratory Society International Congress in September, which demonstrate the ability of a splice variant of histidyl-tRNA synthetase, the active portion of ATYR1923, to disrupt sarcoid granuloma formation in vitro — a hallmark of this debilitating disease,” said Sanjay Shukla, M.D., M.S., President and Chief Executive Officer of aTyr. “The research generated from this collaboration may help direct us to biomarkers indicative of a population that may be sensitive to treatment with ATYR1923, which could lead to improved patient outcomes.”
Sarcoidosis is an inflammatory disease characterized by the formulation of granulomas, clumps of inflammatory cells, in one or more organs of the body. Sarcoidosis in the lungs is called pulmonary sarcoidosis and occurs in more than
Dr. Crouser received his medical degree from the Medical College of Ohio at Toledo, OH. He completed an internship, residency and fellowship at The Ohio State University Wexner Medical Center in Columbus, OH. He is board certified in Internal Medicine with subspecialty certifications in Pulmonary Disease and Critical Care. He is a leader in sarcoidosis research and treatment and currently serves as the Chair of the Foundation for Sarcoidosis Research’s Scientific Advisory Board. In 25 years, his laboratory has contributed to the publication of more than 100 peer-reviewed manuscripts, including the first clinical practice guidelines for sarcoidosis, which were endorsed by the American Thoracic Society in 2020. Ohio State’s Sarcoidosis Specialty Clinic was named a Center of Excellence in 2020 by the World Association of Sarcoidosis and Other Granulomatous Disorders.
About ATYR1923
aTyr is developing ATYR1923 as a potential therapeutic for patients with severe inflammatory lung diseases. ATYR1923, 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 the innate and adaptive immune response in inflammatory disease states. aTyr has completed enrollment in a proof-of-concept Phase 1b/2a trial evaluating ATYR1923 in patients with pulmonary sarcoidosis. This Phase 1b/2a study is a multi-ascending dose, placebo-controlled, first-in-patient study of ATYR1923 that has been designed to evaluate the safety, tolerability, steroid sparing effect, immunogenicity and pharmacokinetic profile of multiple doses of ATYR1923. Proof-of-mechanism for ATYR1923 was established in a Phase 2 clinical trial in COVID-19 patients with severe respiratory complications, which demonstrated that ATYR1923 reduced inflammatory cytokine levels in patients consistent with preclinical models, including cytokines that are implicated in sarcoidosis and other forms of interstitial lung disease.
About aTyr
