“We are excited to present a thorough summary of our preclinical work from our ATYR1923 program, specifically as it relates to potential activity in interstitial lung diseases at the ATS International Conference in San Diego next week,” commented David King, Ph.D., Chief Scientific Officer of aTyr. “In addition, we recently completed enrollment in our ongoing Phase 1 healthy volunteer study with ATYR1923, dosing 36 subjects across six cohorts at dose levels up to 5 mg/kg. We expect to announce top-line results including pharmacokinetic and safety data from this study next month.”   

Poster Presentation: Sunday May 20, 2018 from 9:15 – 11:15 AM (CDT)

Title:Preclinical Characterization of ATYR1923 (iMod.Fc), an Immune-Modulatory Therapeutic with Potentially Broad Application in Interstitial Lung Diseases”

Presenter: Kathleen Ogilvie, Ph.D., aTyr Pharma, Inc.

Conclusions:

  • ATYR1923 has been engineered to have a long duration of action and is efficacious in bleomycin-induced lung fibrosis preclinical models when administered weekly.
  • Data demonstrates that ATYR1923 dosing results in improved lung function and reduced inflammation after bleomycin induced lung injury in rats.
  • Pharmacokinetic data in rats and nonhuman primates predict once monthly dosing in patients.
  • Favorable safety profile observed from one- and three-month GLP toxicity studies in rats and nonhuman primates at weekly doses up to 60mg/kg with no observed adverse effects.
  • Based on the preclinical data, a Phase 1 first–in-human clinical study was initiated.
