Cyclin Dependent Kinase 2 (CDK2) Inhibitors in Oncology Clinical Trials: A Review.

Cyclin dependent kinase 2 (CDK2) is responsible for enforcing progression through the G1-S phase transition. Mutations and alterations in the CDK2 signaling pathway are associated with various cancers, most commonly breast, ovarian, prostate, leukemia, and lymphoma. CDK2 inhibitors have shown promising preclinical and early clinical results, and this class of agents may be most effective against cancers with cyclin E overactivity. Common side effects observed include nausea, vomiting, diarrhea, anemia, and fatigue. This clinical review summarizes past and current CDK2 inhibitors in clinical trials.
