Phase 2
Completed
Conditions

Acute Myeloid Leukemia
Myeloproliferative/Myelodysplastic Neoplasm
Interventions
Drug: Induction Chemotherapy
Drug: Consolidation Chemotherapy
Drug: Autologous Stem Cell Transplantation
Drug: Allogeneic Stem Cell Transplantation
Registration Number
NCT02084563
Lead Sponsor
Hospital Israelita Albert Einstein
Brief Summary

The objective of this study is to describe the prevalence and prognostic impact of the most common genetic abnormalities in patients with Myeloid Neoplasms, including Acute Myeloid Leukemia (AML), Myeloproliferative Neoplasms (MPN), Myelodysplastic Syndromes (MDS) and Myeloproliferative/Myelodysplastic Neoplasms. Patients will have samples of blood and/or bone marrow collected and sent to Hospital Israelita Albert Einstein for analysis and storage.

Patients with a diagnosis of Acute Myeloid Leukemia will be treated according to an uniform protocol.

GroupInterventionDescription
AML-Non-intensive chemotherapyLow Dose CytarabinePatients with acute myeloid leukemia not fit for intensive chemotherapy Patients will receive induction chemotherapy with either low dose cytarabine or decitabine. Assignment to each drug will depend on drug availability and physician discretion. No randomization will be done between the drugs. Cycles will be repeated every 28 days. Patients who achieve CR will continue to post-consolidation therapy with either cytarabine or decitabine, based on the induction therapy received. Patients will receive a maximum of 4 cycles until achieving CR, if no response is seen after 4 cycles patients will be deemed refractory.
AML-Intensive ChemotherapyInduction ChemotherapyPatients with Acute Myeloid Leukemia fit for intensive chemotherapy Patients will receive Induction Chemotherapy, and CR will be evaluated after 28 days. Patients who achieve CR post-induction chemotherapy will receive post-remission therapy according to risk: * Low risk patients: Consolidation chemotherapy or Autologous stem cell transplantation * Intermediate and high-risk patients: Allogeneic stem cell transplantation Patients who do not achieve CR may receive one second induction cycle, and if CR is achieved may proceed to post-remission therapy as per above. Patients who do not achieve CR after two cycles of induction will be deemed refractory and removed from the study.

Primary Outcome Measures
NameTimeMethod
Prevalence of molecular and cytogenetic abnormalities2 years

As assessed by results of molecular and cytogenetic tests and frequency in the population studied

Secondary Outcome Measures
NameTimeMethod
Response rate1 month

Evaluate complete remission (CR) rate at 1 month for patients with Acute Myeloid Leukemia who received induction chemotherapy. Complete remission was defined by the presence of \< 5% blasts in the bone marrow (BM) with \> 1 x 10\^9/L neutrophils and \>100x10\^9/L platelets in the peripheral blood (PB)

Number of participants with adverse events as a measure of safety and tolerability1 year

Evaluate hematological and non-hematological toxicity in patients with Acute Myeloid Leukemia treated according to the protocol. Toxicity will be graded as per the National Cancer Institute Common Toxicity Criteria for Adverse Events v4.0.3

Cumulative Incidence of Transformation to Acute Myeloid Leukemia5 years

Evaluate 5-years incidence of transformation to Acute Myeloid Leukemia in patients with Myeloproliferative Neoplasms, Myelodysplastic Syndromes and Myeloproliferative/Myelodysplastic Neoplasms

Overall survival5 years

Evaluation of 5-years overall survival in patients with Acute Myeloid Leukemia, Myeloproliferative Neoplasms, Myelodysplastic Syndromes and Myeloproliferative/Myelodysplastic Neoplasms

Cumulative incidence of relapse and non-relapse mortality5 years

Evaluate 5-years cumulative incidence of relapse and non-relapse mortality in patients with Acute Myeloid Leukemia who achieve complete remission following induction chemotherapy
