aTyr Pharma Announces Completion of Enrollment in Phase 1b/2a Clinical Trial of ATYR1923 in Patients with Pulmonary Sarcoidosis
The company expects to report data from this trial in the third quarter of 2021. Results of this study will inform future development for ATYR1923 in ILD, which may include a registrational trial in pulmonary sarcoidosis and expansion into trials for other forms of ILD.
“We are pleased to meet the target enrollment of this important study, especially during the COVID-19 pandemic. Reaching this significant milestone for our ATYR1923 clinical program and the interest we’ve seen from patients to join the trial highlights the need for new therapies for this chronic, debilitating disease,” said
The Phase 1b/2a study is a multiple-ascending dose, double-blind, placebo-controlled study that is designed to evaluate the safety, tolerability, immunogenicity and pharmacokinetic profile of multiple doses of ATYR1923 compared to placebo, as well as to evaluate preliminary efficacy measures including steroid sparing effect, measures of lung function and potential disease biomarkers.
“Treatment options remain limited for pulmonary sarcoidosis, which affects around 200,000 people in the
In addition to pulmonary sarcoidosis, ATYR1923 is being evaluated in a Phase 2 trial in hospitalized COVID-19 patients with severe respiratory complications, which include an acute form of interstitial pneumonia. The company recently completed enrollment in this study and expects to report topline data in the coming weeks.
aTyr is developing ATYR1923 as a potential therapeutic for patients with 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 is currently enrolling a proof-of-concept Phase 1b/2a trial evaluating ATYR1923 in patients with pulmonary sarcoidosis, a form of interstitial lung disease. 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 pharmacokinetics profile of multiple doses of ATYR1923. In response to the COVID-19 pandemic, aTyr initiated and completed enrollment in a Phase 2 clinical trial with ATYR1923 in COVID-19 patients with severe respiratory complications. This Phase 2 study is a randomized, double blind, placebo-controlled study that has been designed to evaluate the safety and preliminary efficacy of a single dose of ATYR1923.
aTyr is a biotherapeutics company engaged in the discovery and development of innovative medicines based on novel biological pathways. aTyr’s research and development efforts are concentrated on a newly discovered area of biology, the extracellular functionality and signaling pathways of tRNA synthetases. aTyr has built a global intellectual property estate directed to a potential pipeline of protein compositions derived from 20 tRNA synthetase genes and their extracellular targets. aTyr’s primary focus is ATYR1923, a clinical-stage product candidate which binds to the neuropilin-2 receptor and is designed to down-regulate immune engagement in inflammatory lung diseases.
