A Phase 1b Study of Oral Chk1 Inhibitor LY2880070 as Monotherapy in Patients with Advanced or Metastatic Cancer

Publication: ASCO
Division: Cognigen


In the context of DNA damage, Checkpoint Kinase 1 (Chk1) mediates a checkpoint response which arrests the cell cycle and allows the cell to complete DNA repair and replication. LY2880070(LY) is a selective adenosine triphosphate-competitive inhibitor of Chk1. Chk1 overexpression has been found in a variety of cancers. The safety of patients who are CYP2D6 poor metabolizers is an important consideration.
