Description: Sapacitabine is an orally bioavailable pyrimidine analogue prodrug with potential antineoplastic activity. Sapacitabine is hydrolyzed by amidases to the deoxycytosine analogue CNDAC (2'-Cyano-2'-deoxyarabinofuranosylcytosine), which is then phosphorylated into the active triphosphate form. As an analogue of deoxycytidine triphosphate, CNDAC triphosphate incorporates into DNA strands during replication, resulting in single-stranded DNA breaks during polymerization due to beta-elimination during the fidelity checkpoint process; cell cycle arrest in the G2 phase and apoptosis ensue. The unmetabolized prodrug may exhibit antineoplastic activity as well.

Additional Information

Both sapacitabine and its major metabolite, CNDAC, have demonstrated potent anti-tumor activity in both blood and solid tumors in preclinical studies. In a liver metastatic mouse model, sapacitabine was shown to be superior to gemcitabine (Gemzar®; Lilly) or 5-FU, two widely used nucleoside analogs, in delaying the onset and growth of liver metastasis. Cyclacel has initiated a number of clinical trials to evaluate sapacitabine in both solid and hematological tumors laying the foundation for future Phase 2 studies and combination studies with other anti-cancer agents. Three Phase 1 studies have been completed, which evaluated safety and pharmacokinetics of a variety of dosing schedules in approximately 120 patients with solid tumors. Sapacitabine is currently being evaluated in two Phase 2 trials in patients with advanced cutaneous T-cell lymphoma (CTCL) and in elderly patients with acute myeloid leukemias (AML).  See .
