About this trial

This phase I/II trial finds the best dose, side effects and how well giving venetoclax in combination with cladribine, cytarabine, granulocyte colony-stimulating factor, and mitoxantrone (CLAG-M) in treating patients with acute myeloid leukemia and high-grade myeloid neoplasms. Venetoclax may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Chemotherapy drugs, such as cladribine, cytarabine, and mitoxantrone, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving venetoclax with CLAG-M may kill more cancer cells.

Eligibility criteria

Qualifiers

Diagnosis of acute myeloid leukemia (per the World Health Organization [WHO] 2016 classification) or high-grade myeloid neoplasm (>= 10% myeloid blasts in peripheral blood or marrow as assessed by morphology or multiparameter flow cytometry at initial presentation). Patients with biphenotypic or mixed phenotype acute leukemia are eligible.

Newly diagnosed patients presenting for trial entry must have adverse risk disease as per the European LeukemiaNet 2017 guidelines

Relapsed/refractory patients presenting for trial entry must require first or subsequent salvage therapy and have detectable blasts in peripheral blood or >= 5% blasts in bone marrow, as assessed by morphology or multiparameter flow cytometry; or extramedullary myeloid sarcoma, per European LeukemiaNet 2017 guidelines.

These patients are only allowed in the phase 1 portion of the trial

Disqualifiers

Acute promyelocytic leukemia or chronic myeloid leukemia in myeloid blast crisis

Known active central nervous system (CNS) involvement with acute myeloid leukemia (AML)

Concomitant illness associated with a likely survival of < 1 year

Active systemic infection, unless disease is under treatment with antimicrobials and considered controlled or stable; patients with fever thought to be likely secondary to leukemia are eligible. Patients with chronic hepatitis B virus (HBV) or hepatitis C (HCV) requiring treatment would be excluded. Note: subjects with serologic evidence of prior vaccination to HBV (i.e. hepatitis B surface [HBs] antigen negative-, anti-HBs antibody positive and anti-hepatitis B core [HBc] antibody negative) or positive anti-HBc antibody from intravenous immunoglobulins (IVIG) may participate
