About CYC065

CYC065, a second generation CDK2/9 inhibitor, is being evaluated in a first-in-human, Phase 1 trial in patients with advanced solid tumors. It is mechanistically similar but has higher dose potency, in vitro and in vivo, and improved properties compared to seliciclib, a first generation CDK inhibitor. Similarly to FDA approved CDK4/6 inhibitors, CYC065 may be most useful in combination with other anticancer drugs, including Bcl-2 inhibitors, such as venetoclax, or HER2 inhibitors, such as trastuzumab.  Preclinical data show that CYC065 may benefit patients with adult and pediatric hematological malignancies, including acute myeloid leukemias (AML), acute lymphocytic leukemias (ALL), and in particular those with MLL rearrangements, chronic lymphocytic leukemias (CLL), B-cell lymphomas, multiple myelomas, and certain solid tumors, including breast and uterine cancers, and neuroblastomas.
