• Written informed consent has been obtained prior to the performance of any protocol-specific procedure.
• The patient is >= 18 years of age at the time of signature of the informed consent form.
• Eastern Cooperative Oncology Group performance status of 0, 1 or 2.

• Adequate hepatic and renal function defined as:

  • Serum bilirubin < 1.5 times the Upper Limit of Nor-mal (ULN).
  • Serum alanine aminotransferase < 2.5 times the ULN.
  • Calculated creatinine clearance > 50 mL/min.
• If the patient is female, she must be of non-childbearing potential, i.e. have a current tubal ligation, hysterectomy, ovariectomy or be post-menopausal, or if she is of childbearing potential, she must practice adequate con-traception for 30 days prior to treatment administration, have a negative pregnancy test and continue such pre-cautions for two months after completion of the treatment administration series.

Exclusion Criteria:

• The patient is in morphologic leukemia-free state or in morphologic complete remission with incomplete blood count recovery (CRi).

• The patient has received, or is receiving induction chemotherapy followed by Stem Cell Transplantation.
• The patient has (or has had) previous or concomitant malignancies, except effectively treated malignancy that is considered by the investigator highly likely to have been cured.
• The patient has hypercalcemia.
• The patient is known to be HIV-positive.
• The patient has symptomatic autoimmune disease such as, but not limited to multiple sclerosis, lupus, and in-flammatory bowel disease.
• The patient has a history of allergic reactions likely to be exacerbated by any component of the study investigational product.
• The patient has other concurrent severe medical prob-lems, unrelated to the malignancy, that would significantly limit full compliance with the study or expose the patient to unacceptable risk.

• The patient has psychiatric or addictive disorders that may compromise his/her ability to give informed consent, or to comply with the study procedures.
• The patient has received any investigational or non-registered medicinal product other than the study medi-cation within 30 days preceding the first dose of study medication or plans to receive such a drug during the study period.
• The patient requires concomitant treatment with systemic corticosteroids or any other immunosuppressive agents. The use of prednisone, or equivalent, <0.5 mg/kg/day (absolute maximum 40 mg/day), or inhaled corticosteroids or topical steroids is permitted.
• The patient has received intravenous administration of antibiotics within 2 weeks prior to first study treatment or oral antibiotics within 1 week prior to first study treatment.
