The clinical candidate, ASTX029, is a novel, dual mechanism ERK1/2 Inhibitor and has potent activity in MAPK-activated cancer cell lines and in vivo tumor models

Summary

  • The MAPK signaling pathway is commonly upregulated in human cancers due to oncogenic mutations of upstream
    components such as BRAF or KRAS.
  • MAPK pathway inhibition has been clinically validated by BRAF and MEK inhibitors.
  • As the final node in the MAPK pathway, ERK is an attractive therapeutic target for the treatment of MAPK-activated cancers, including those resistant to upstream inhibition.
  • Previously we described the fragment-based discovery of a chemical series targeting ERK[1]. Here we disclose for the first time the structure of the clinical candidate, ASTX029.
