aTyr Pharma, Inc. (NASDAQ:ATYR) announced published research demonstrating the anti-fibrotic properties of its investigational fusion protein candidate, ATYR0101. Findings show that ATYR0101 targets specific extracellular proteins to trigger the death of myofibroblasts, which are central drivers of chronic tissue scarring across multiple organ systems.

In animal models of lung fibrosis, ATYR0101 significantly decreased collagen content and reduced overall fibrosis scores compared to the established anti-fibrotic drug nintedanib. The results suggest the candidate could potentially disrupt and help restore tissue in conditions such as idiopathic pulmonary fibrosis, where current treatments primarily slow disease progression.

ATYR0101 is currently undergoing investigational new drug (IND) enabling studies, with clinical trials expected to begin in 2027. Shares of aTyr Pharma fell 12.75% to $0.2148 following the announcement.
