Summary:

      The purpose of this study is to evaluate the clinical activity and safety of a WT1
      Antigen-Specific Cancer Immunotherapeutic (WT1 ASCI) as post-induction therapy in adult
      patients with WT1-positive AML presenting a suboptimal clinical response to induction
      chemotherapy. The study will also assess whether this treatment induces a specific immune
      response to the malignancy.
    

Eligibility criteria:

        Inclusion Criteria:

          -  The patient has cytologically proven AML as defined by the World Health Organization

          -  The leukemia is a de novo or secondary AML.

          -  The patient's blasts cells show expression of WT1 transcript, detected by quantitative
             Reverse Transcription-Polymerase Chain Reaction (qRT-PCR).The patient received the
             following therapy according to the Institution's standard of care.

               -  For patients < 60 years old: at least two induction chemotherapy treatments.

               -  For patients >= 60 years old: at least one induction chemotherapy treatment or
                  alternative treatment.

          -  The first ASCI administration should be given within one year after the last
             chemotherapy administration. All screening procedures should be completed within seven
             weeks before the first ASCI administration.

          -  In the investigator's opinion and in compliance with the Institution Hematology Tumor
             Board's guidances, the patient should not be eligible for any additional chemotherapy
             treatment before the ASCI treatment.

          -  The clinical status of the patient at inclusion is one of the following:

               -  Partial Remission (PR)

               -  Morphologic complete remission with incomplete blood count recovery (CRi)

          -  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 first 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 ALT < 2.5 times the ULN.

               -  Calculated creatinine clearance > 50 mL/min.

          -  In the view of the investigator, the patient can and will comply with the requirements
             of the protocol.

          -  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, then she must practice adequate contraception for 30 days
             prior to treatment administration, have a negative pregnancy test and continue such
             precautions for 2 months after completion of the treatment administration series.

        Exclusion Criteria:

          -  The patient was diagnosed with leukemic Central Nervous System (CNS) disease (e.g.
             before chemotherapy) or presents neurological symptoms at baseline suggestive of a CNS
             involvement.

          -  The patient has acute promyelocytic leukemia with t(15;17) (q22;q12), (PML/RARα) or

          -  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.
