Clinical Trials

Several Phase 1/2 clinical trials, sponsored by Bristol-Myers Squibb in collaboration with Exelixis, have evaluated the safety, pharmacokinetics, and pharmacodynamics of XL413 (BMS-863233) in human subjects. These multiple ascending dose protocols targeted patient populations suffering from advanced solid cancers, metastatic cancer, and refractory hematologic malignancies. According to current records, all of these clinical trials have been officially terminated.

Compliance for Clinical Use

Mechanism and Biochemical Profile

XL413 Hydrochloride acts as a potent and selective inhibitor of cell division cycle 7 homolog (CDC7) kinase with an IC50 of 3.4 nM, effectively preventing downstream phosphorylation of MCM2 to disrupt the initiation of genomic DNA replication. By halting S-phase cell cycle progression and suppressing aberrant cell proliferation, this targeted mechanism seeks to inhibit tumor growth in patients with advanced solid cancers, metastatic tumors, and refractory hematologic malignancies.
