\- M3 (acute promyelocytic leukemia)
* all cases of de novo AML or secondary AML with ≥ 20 % blasts in peripheral blood and/or bone marrow, except:
* AML secondary to myeloproliferative neoplasms (MPN)
* AML secondary to exposure of leukemogenic agents (t-AML) unless treated with CPX-351 chemotherapy or hypomethylating agents combined with venetoclax.
* Completion of one of the following treatment options:
* I) Intensive chemotherapy:
* (1) at least one cycle of induction chemotherapy and one cycle of consolidation chemotherapy (low-dose cytarabine as consolidation therapy is allowed) OR
* (2) one to two cycles of CPX-351 induction treatment and up to two cycles of CPX-351 consolidation treatment OR
* II) Low-intensity chemotherapy:
* (3) at least two cycles to maximum six cycles of hypomethylating agents whether or not combined with venetoclax OR
* (4) at least two cycles to maximum six cycles of low-dose cytarabine combined with venetoclax;
* resulting in:
* morphological complete remission (CR), i.e. bone marrow blast count \<5% with neutrophil count \>1000 cells/µL and platelet count \>100,000 cells/µL OR
* morphological complete remission with incomplete blood recovery (CRi), i.e. bone marrow blast count \<5% with neutrophil count \<1000 cells/µL or platelet count \<100,000 cells/µL.
For the purpose of this study protocol, platelet count must be \>50,000 cells/µL.
* Adult (≥ 18 years) at very high risk of relapse according to:
* Age ≥ 60 years, and/or
* Adverse biological features (e.g. adverse cytogenetics, adverse morphological features, adverse molecular features, hyperleukocytosis (\> 100000 cells/µL)), and
* Ineligible for or unwilling to receive hematopoietic stem cell transplantation.
* WHO performance status: grade 0, 1 or 2 at the time of enrollment. For definition of performance status, see: http://www.ecog.org/general/perf\_stat.html
* Absence of any psychological, familial, sociological, geographical or physical condition potentially hampering compliance with the study protocol and follow-up schedule; those conditions should be discussed with the patient before study entry.
Exclusion Criteria:

A minimum of 4 weeks must have elapsed between the last dose of immunosuppressive therapy and the first vaccination. Topical corticosteroids are permitted, except if applied at the sites of DC injection.

登记简述
本项创新免疫治疗研究的首要目标是确定:在我们既往Ⅰ/Ⅱ期研究中观察到的抗白血病作用,能否在更大患者队列中得到证实;以及树突状细胞疫苗能否通过清除微小残留病,显著预防复发并延长急性髓系白血病(AML)患者生存。

The primary aim of this innovative immunotherapeutic study is to determine whether the antileukemic effects seen in our previous phase I/II study can be confirmed in a large cohort of patients and whether dendritic cell vaccination can significantly prevent relapse and increase survival of acute myeloid leukemia (AML) patients by eradicating minimal residual disease.
