Description
The purpose of this study is to test the safety of an investigational study drug called AMG-232 in combination with treatment called decitabine. Decitabine is approved by the FDA to treat myelodysplastic syndromes (MDS). Decitabine has not been approved by the FDA to treat patients with AML and is considered investigational or experimental. Decitabine is the standard of care backbone for newly diagnosed elderly patients with AML and is also frequently used for relapsed or refractory patients with AML. Both AMG-232 and decitabine have already been tested in human by themselves, but not in combination. The combination has been tested in animals, but not yet in people and is experimental. This study tests different doses of AMG-232 with standard doses of decitabine but given longer (for 10 days) to see which dose is safer in people.

MDM2 inhibitor AMG-232 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as decitabine, 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 MDM2 inhibitor AMG-232 together and decitabine together may work better in treating patients with acute myeloid leukemia.
This study requires

You are being asked to take part in this study because you have Acute Myeloid Leukemia. You have may have been treated with chemotherapy, and your disease is now growing, or you may have been newly diagnosed with the disease.

Who can participate

Inclusion criteria:

  • Relapsed/refractory AML (>= 5% blasts in bone marrow or extramedullary leukemia) or newly diagnosed AML patients who are not candidates for (age >= 70 years; adverse cytogenetics, e.g., as defined by the Medical Research Council [MRC] Prognostic Groupings; secondary AML; organ dysfunction arising from significant co-morbidities not directly linked to leukemia; Eastern Cooperative Oncology Group [ECOG] = 2) or not willing to undergo intensive chemotherapy; Note that both relapsed/refractory and newly diagnosed AML patients will be eligible for the dose escalation part of the study, but only newly diagnosed patients will be eligible for the dose expansion cohort
  • Patients must have measureable disease as defined the presence of >= 5% blasts in bone marrow or extramedullary leukemia
  • Eligible patient must show evidence of wild-type (WT) p53 as assessed by central DNA sequencing conducted at Dr. Jeffrey Sklar's laboratory at Yale University Cancer Center; note, that since patients with AML have a rapidly proliferating disease, patient can be enrolled and begin treatment prior to obtaining the results of this test; patients who are found to the TP53 mutated will be removed from study and can continue on single agent decitabine; however patients will continue to be followed for toxicity
  • ECOG performance status =< 2 (Karnofsky >= 60%)
  • Total bilirubin < 1.5 x institutional upper limit of normal (ULN) (< 2.0 x ULN for subjects with documented Gilbert's syndrome or < 3.0 x ULN for subjects for whom the indirect bilirubin level suggests an extrahepatic source of elevation)
  • Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT]) and alanine aminotransferase (ALT) (serum glutamic pyruvic transaminase [SGPT]) =< 2.5 x ULN
  • Alkaline phosphatase < 2.0 x ULN (if liver or bone metastases are present, < 3.0 x ULN)
  • Body surface area (BSA)-normalized creatinine clearance >= 30 mL/min/1.73 m^2 (using Cockcroft-Gault creatinine clearance [CrCl])
  • Prothrombin time (PT) or partial thromboplastin time (PTT) < 1.5 x upper limit of normal (ULN), OR international normalized ratio (INR) < 1.5
  • Patient must be willing to submit the blood sampling and bone marrow sampling for the PK and PD analyses and exploratory biomarkers
  • Women of child-bearing potential must agree to use adequate contraception prior to study entry and for the duration of study participation through 5 weeks (women) after receiving the last dose of AMG 232; should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately; men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of study participation, and 3 months after completion of AMG 232 administration
  • Adequate methods of effective birth control include sexual abstinence (men, women); vasectomy; or a condom with spermicide (men) in combination with barrier methods, hormonal birth control or intrauterine device (IUD) (women)
  • Ability to understand and the willingness to sign a written informed consent document

Exclusion criteria:

  • Patients with previously untreated AML with core binding factor (CBF) chromosomal aberrations (inv[16]/t[16;16] or t[8;21]); Note that patients with relapsed or refractory AML with CBF chromosomal aberrations will be eligible
  • Unresolved toxicities from prior anti-tumor therapy, defined as not having resolved to Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 grade 0 or 1, or to levels dictated in the eligibility criteria with the exception of alopecia (grade 2 or 3 toxicities from prior antitumor therapy that are considered irreversible [defined as having been present and stable for > 6 months], such as ifosfamide-related proteinuria, may be allowed if they are not otherwise described in the exclusion criteria AND there is agreement to allow by both the investigator and sponsor)
