Cyclacel Pharmaceuticals, Inc. is a clinical-stage biopharmaceutical company. The Company is focused on developing cancer medicines based on cell cycle, transcriptional regulation and mitosis control biology. The transcriptional regulation program is evaluating fadraciclib, a Cyclin-dependent kinase 9 (CDK9) inhibitor, in solid tumors and hematological malignancies. The anti-mitotic program is evaluating plogosertib, a PLK1 inhibitor, in solid tumors and hematological malignancies. The Company's Mitosis Regulation program includes Plogosertib, which is a novel, small molecule, selective and potent Polo-like kinase 1 (PLK1) inhibitor. Plogosertib has demonstrated potent and selective target inhibition (PLK1 IC50 approximately 3 nM) and impressive efficacy in human tumor xenografts at non-toxic doses. Its translational biology program supports the development of plogosertib in acute leukemias and solid tumors.
