Abstract Number: 2083
Title: Discovery of ETX-19477, a novel and selective PARG inhibitor with high potency against tumors with underlying replication stress
Session Title: Novel Targets and Pathways
Session Date and Time: April 8, 2024, 9:00 AM ? 12:30 PM (PDT)

About ETX-19477

The company's lead asset, ETX-19477, is a novel and potent small molecule inhibitor of PARG, a glycohydrolase that plays a pivotal role in the regulation of DNA repair mechanisms and cooperates with PARP to carry out the single-strand break repair cycle. Pharmacological inhibition of PARG results in hyperPARylation, which leads to the death of cancer cells undergoing replication stress. In multiple animal models, ETX-19477 shows potent tumor growth inhibition, and its efficacy is associated with specific biomarker-defined tumors. A Phase I clinical trial is expected to start in the first half of 2024 in patients with advanced solid tumors at multiple sites in the U.S.
