             RAEB , RAEB-t and CMML with WBC < 13000/mm3)

          -  IPSS score 1.5 or higher (IPSS intermediate-2 and high risk categories) at the

             6 cycles of azacitidine single agent at 75 mg/m²/d for 7 days per cycle. Patients with
             a previous dose reduction of AZA may be eligible if the maximum tolerated dose was
             equal to or above 350mg/m2/cycle (i.e. 50 mg/m²/d for 7 days or 75mg/m2/d for 5 days).

          -  Age more or egal to 18 years

          -  ECOG performance status ≤ 2 (cf. appendix 2);

          -  Patient must have adequate organ function as indicated by the following laboratory
             values

        bilirubin levels ≥ 2 mg/dL.

        AST (SGOT) and ALT (SGPT) ≤ 2.5 times ULN Alkaline Phosphatase ≤ 5 X ULN If > 2.5 X ULN,
        then liver fraction should be ≤ 2.5 X ULN a Creatinine clearance should be calculated per

             received compounds with HDAC inhibitor-like activity, such as valproic acid, as
             anti-tumor therapy should not enroll in this study. Patients who have received such
             compounds for other indications, e.g. valproic acid for epilepsy, may enroll after a
             30-day washout period.
