Acute Myeloid Leukemia Clinical Trial
Edetate Calcium Disodium or Succimer in Treating Patients With Acute Myeloid Leukemia or Myelodysplastic Syndrome Undergoing Chemotherapy
Summary
This phase I trial studies the side effects and best dose of edetate calcium disodium or succimer in treating patients with acute myeloid leukemia or myelodysplastic syndrome undergoing chemotherapy. Edetate calcium disodium or succimer may help to lower the level of metals found in the bone marrow and blood and may help to control the disease and/or improve response to chemotherapy.
Full Description
PRIMARY OBJECTIVES:
I. To establish the maximal tolerated dose (MTD) of Phase 1 in acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) patients undergoing therapy combined with succimer (DMSA) and edetate calcium disodium (Ca-EDTA). (Phase I dose escalation) II. To assess the efficacy information regarding the combined therapy in terms of the overall response rate (ORR) including complete remission (CR), CR with partial hematological recovery (CRh), CR with incomplete count recovery (CRi), morphologic leukemia free state (MLFS), and partial remission (PR). (Phase I expansion)
SECONDARY OBJECTIVES:
I. To assess the complete remission (CR), complete remission with incomplete hematologic recovery (CRi), complete remission with partial hematological recovery (CRh), partial remission (PR), hematologic improvement (HI), morphologic leukemia free state (MLFS) rates, cytogenetic response, and the 1-year overall survival (OS) in AML patients and the CR/marrow CR/hematologic improvement (HI) rate, partial remission (PR) rate and 1-year overall survival (OS) and cytogenetic response in MDS patients undergoing MDS/AML therapy combined with DMSA and Ca-EDTA.
II.To assess overall survival and event free survival in AML and MDS patients undergoing AML and MDS therapy combined with DMSA and Ca-EDTA III. To assess remission duration in AML and MDS patients undergoing AML and MDS therapy combined with DMSA and Ca-EDTA.
IV. To monitor toxic and essential metal levels during AML and MDS therapy combined with DMSA and Ca-EDTA and to evaluate the reduction in metals in the bone marrow and blood of newly diagnosed AML and MDS patients undergoing metal detoxification combined with standard AML/MDS therapy.
V. To evaluate the safety profile in AML and MDS patients undergoing AML and MDS therapy combined with DMSA and Ca-EDTA.
VI. Correlate metal and copper isotopic abundance ratios of AML and MDS patients with clinical data, conventional cytogenetics, extensive next generation sequencing (NGS) (300-gene panel), exposure survey data, and clinical outcome data, and to perform a larger analysis by pooling this data with metal/genomic/survey/outcome data obtained on 2017-0937 and PA15-0302.
VII. Estimate the progression rate in MDS patients. VIII. To assess other responses of interest. IX. To compare overall survival and response in this study with historical data of patients who were treated without Ca-EDTA and DMSA.
EXPLORATORY OBJECTIVES:
I. To correlate the degree of metal chelation with the degree of therapeutic response and minimal residual disease (MRD).
II. To collect environmental exposure data on the environmental health assessment survey.
III. To assess P53 folding before and after the first dose of Ca-EDTA chelation in MDS and AML patients.
IV. To study changes in cytogenetic/molecular data during treatment, as well as protein expression data (by immunohistochemistry and/or proteomics) including for transcription factors/tumor suppressors (e.g. TP53 and MYC).
V. To perform pre-clinical proof of concept studies of metals and metal chelators in a variety of AML cells and cell lines including: AML cell lines, primary hematologic malignancy cells, stromal cell lines, and patient-derived stromal cells.
OUTLINE: This is a dose-escalation study. Patients are assigned to 1 of 2 cohorts.
COHORT I: During standard of care chemotherapy, patients receive edetate calcium disodium intravenously (IV) daily over 30 minutes for 4 doses for each cycle. Treatment continues for up to 6 cycles in the absence of disease progression or unacceptable toxicity. Patients also receive up to 12 multivitamin capsules PO daily while on study.
COHORT II: During standard of care chemotherapy, patients receive succimer orally (PO) daily for 8 or 21 days of each cycle beginning day 1. Treatment continues for up to 6 cycles in the absence of disease progression or unacceptable toxicity. Patients also receive up to 12 multivitamin capsules PO daily while on study.
After completion of study treatment, patients are followed up every 3-12 months for up to 10 years.
Eligibility Criteria
Inclusion Criteria:

Diagnosis of any of the following:
Newly diagnosed (or untreated) AML with poor-risk cytogenetics, poor-risk molecular, or secondary AML (i.e. therapy-related or evolved from antecedent hematologic malignancy
Newly diagnosed (or untreated) myeloid blast phase of myeloproliferative neoplasm (MPN) (including myeloid blast phase of chronic myeloid leukemia [CML])
Newly diagnosed (or untreated) high-risk, very-high risk or secondary MDS
Newly diagnosed (or untreated) MDS/MPN (regardless of cytogenetic/molecular status)
Relapsed and/or refractory AML, MDS, MDS/MPN, myeloid blast phase of MPN (including myeloid blast phase of CML) who are either salvage 1 or salvage 2
Patients on non-investigational regimens or on investigational new drug (IND)-exempt MD Anderson studies (for hematologic malignancies) of approved drugs are also eligible
Patients on IND studies (for hematologic malignancies) utilizing Food and Drug Administration (FDA) approved commercially available drugs are eligible
Investigational agents that are not used for treatment of the leukemia per se (e.g. anti-infective prophylaxis or therapy) will be allowed. Other supportive care studies are allowed, even if under an IND
Newly diagnosed MDS or AML, as well as MDS/MPN, myeloid blast phase of MPN (including myeloid blast phase of CML), patients can enroll on this study after start of non-investigational induction therapy, but must be within first 3 cycles of therapy and benefiting from their front-line therapy. Patients with relapsed and/or refractory AML, MDS, MDS/MPN, myeloid blast phase of MPN (including myeloid blast phase of CML) who are either salvage 1 or salvage 2 are eligible for these salvage cohorts if they are within the first 3 cycles of salvage 1 or salvage 2 therapy
Transformed and untreated AML transformed from previously treated MDS, myeloproliferative neoplasm (MPN) or other types of secondary AML are allowed. Myeloid blast phase of MPN and chronic myeloid leukemia (CML) are allowed
