Toxicity and toxicokinetics of the cyclin-dependent kinase inhibitor AG-024322 in cynomolgus monkeys following intravenous infusion

Purpose Cyclin-dependent kinases (CDKs) play a significant role in the control of cell-cycle progression and exhibit aberrant regulation in various neoplastic diseases. AG-024322 is a potent inhibitor of CDK1, CDK2, and CDK4 that produces cell-cycle arrest and antitumor activity in preclinical models. This study evaluated the toxicity of AG-024322 when given by intravenous (IV) infusion to cynomolgus monkeys, including reversibility of effects.
