Dacogen Maintenance in AML – pro

Dacogen (decitabine) is a new drug, a DNA methyltransferase inhibitors (DMTI), that approved by the FDA for use in all French- American British (FAB) categories for MDS. This drug is now FDA approved for MDS. For acute myelogenous leukemia (AML), less is known. A 2007 review, looked at 33 patients with the World Health Organization (WHO) criteria of AML that were treated with decitabine alone (23 patients) or in combination with valproic acid (10 patients) as first-line therapy. There were 20 men (61%) and their median age was 72, range 39 to 85. Median bone marrow blasts at study entry was 26%, and 14 (42%) had >30% blasts. There were three different schedules of decitabine IV, which gave a total of 100–150 mg/m2/course over 3–10 days. Of the 33 patients treated, there were 8 CRs (24%) and 9 marrow CR/PR/Hematologic improvement (27%) for a total response rate of 17 (52%). Overall mortality at 4 weeks and 8 weeks was 3% and 15%, respectively. At a median follow-up of 20 months, median survival of the entire group was 12.6 months (95% CI: 6.5–23.0), and 2-year survival was 25% (95% CI: 13–48), which compares favorably to reported AML survival in this age group in the United States. The study concluded that decitabine is an effective and less toxic treatment in this AML age group and may prolong survival compared with supportive care. MGI Pharma is currently conducting a phase III pivotal trial to evaluate Dacogen in patients with AML. Additional phase II studies are also underway to evaluate alternative dosing regimens for Dacogen in patients with MDS, AML and chronic myelogenous leukemia. For maintenance there is: Decitabine as Maintenance Therapy After Standard Therapy in Treating Patients With Previously Untreated Acute Myeloid Leukemia, NCT00416598.

NCCN lists both Dacogen and Vidaza for low intensity therapy on p. AML-11
