NCT03630991

Brief 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.

Outcome Measures

Primary Outcomes (2)

  • Incidence of adverse events

    Safety data of the patients will be summarized using descriptive statistics such as mean, standard deviation, median and range. Will follow standard reporting guidelines for adverse events. Safety data will be summarized by category, severity and frequency.

    At 30 days post-treatment

  • Maximum tolerated doses (MTD) of edetate calcium disodium (Ca-EDTA) and succimer (DMSA) (Phase 1 dose escalation)

    The MTD is the highest dose level in which \< 2 patients of 6 develop first cycle dose-limiting toxicity (DLT).

    Up to the end of cycle 1 (each cycle is 28 days)

Study Arms (2)

Cohort I (edetate calcium disodium, multivitamin)

EXPERIMENTAL

During standard of care chemotherapy, patients receive edetate calcium disodium 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. DOSE EXPANSION: During standard of care chemotherapy, patients receive edetate calcium disodium IV daily over 30 minutes for 4 doses for each cycle. DMSA daily for 21 days. Multivitamin capsules daily while on study. Patients will receive treatment for up to 6 cycles in the absence of disease progression or unacceptable toxicity.

Drug: Edetate Calcium DisodiumDietary Supplement: Multivitamin

Cohort II (succimer, multivitamin)

EXPERIMENTAL

During standard of care chemotherapy, patients receive succimer 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. DOSE EXPANSION: During standard of care chemotherapy, patients receive edetate calcium disodium IV daily over 30 minutes for 4 doses for each cycle. DMSA daily for 21 days. Multivitamin capsules daily while on study. Patients will receive treatment for up to 6 cycles in the absence of disease progression or unacceptable toxicity.
