Description: GDC-0425, also known as RG7602. is an oral, selective Chk1 inhibitor. GDC-0425 enhances gemcitabine (gem) efficacy in tumor xenograft models. Greater chemopotentiation is observed in cancer cell lines lacking p53 activity. GDC-0425 blocks the function of a protein called checkpoint kinase 1 (Chk1). GDC-0425 was safe and yielded responses in patients with a variety of cancer types, including triple-negative breast cancer, melanoma, and cancer of unknown primary, according to data from a phase I clinical trial presented at the AACR Annual Meeting 2015, held April 18-22.
