division cycle. Both sapacitabine and its major metabolite, CNDAC, have demonstrated in preclinical studies potent anti-tumor activity in both hematological and solid tumors. Sapacitabine has been administered to approximately 150 patients enrolled in three Phase I clinical trials in solid tumors and a Phase I study in hematological tumors conducted by Dr. Hagop Kantarjian, Professor of Medicine and Chairman of the Leukemia Department at M.D. Anderson Cancer Center (UTMDACC) in Houston, Texas. Based on the results of these studies, Cyclacel plans to initiate Phase II trials of sapacitabine in 2007 to evaluate the drug in both hematological and solid tumors.
