Clinical Trial Summary

The purpose of this study is to assess whether treatment with cenersen in combination with 4 cycles of high and low-dose chemotherapy (idarubicin and cytarabine) improves the complete response rate in acute myelogenous leukemia (AML) patients ≥ 55 years of age who did not show a response (CR, CRi, or PR) to a single aggressive frontline induction course.


Clinical Trial Description

Cenersen is a phosphorothioate antisense oligonucleotide of sequence 5'-CCCTG5-CTCCC10-CCCTG15-GCTCC20-3'. For AML, cenersen is specific for blocking p53 expression in the stem cells. When AML stem cells are dividing, cenersen sensitizes them to even low-level DNA damage of the type caused by idarubicin, etoposide and possibly ara-C.

Because AML stem cells are not all dividing at any given time, this protocol is designed to treat patients with a total of four cycles of cenersen plus chemotherapy within a two to three month period. For a limited period of time, proliferating non-stem cells can be expected to maintain or even expand the tumor while the stem cells are being depleted. If the proliferating non-stem cells are not resupplied by the stem cells, they will all become end stage blasts after a few divisions and undergo elimination. ;
