testing a new chemotherapy drug, krt-232 (amg-232) in combination with decitabine and venetoclax in patients with acute myeloid leukemia

Conditions: Acute Myeloid Leukemia; Recurrent Acute Myeloid Leukemia; Refractory Acute Myeloid Leukemia; Secondary Acute Myeloid Leukemia

Summary: this phase ib trial studies the side effects and best dose of navtemadlin when given together with decitabine and venetoclax in treating patients with acute myeloid leukemia that has come back after a period of improvement (recurrent), does not respond to treatment (refractory), or is newly diagnosed. navtemadlin may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. chemotherapy drugs, 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. venetoclax is in a class of medications called b-cell lymphoma-2 (bcl-2) inhibitors. it may stop the growth of cancer cells by blocking bcl-2, a protein needed for cancer cell survival. giving navtemadlin, decitabine, and venetoclax together may work better than decitabine alone in treating patients with acute myeloid leukemia.

primary objective: i. to evaluate the toxicities of navtemadlin (krt-232 \[amg-232\]) in combination with decitabine (20 mg/m\^2 for 10 days), and venetoclax, and to determine the maximum tolerated dose (mtd)/recommended phase 2 dose (rp2d) of krt-232 (amg-232) in combination with a standard dose of decitabine and venetoclax. secondary objectives: i. to evaluate the pharmacokinetic (pk) profiles of krt-232 (amg-232), venetoclax, and decitabine when used in combination. ii. to evaluate p53 signaling induced by krt-232 (amg-232), venetoclax, and decitabine as measured by mic-1 induction. iii. to correlate krt-232 (amg-232), venetoclax and decitabine exposure with pharmacodynamics endpoints (efficacy, toxicity, changes in p53 signaling). exploratory objectives: i. to evaluate the response rate (rr) and progression free survival (pfs) of krt-232 (amg-232), venetoclax, and decitabine in acute myeloid leukemia (aml). ii. to evaluate potential predictive biomarkers of response to krt-232 (amg-232), venetoclax, and decitabine in aml. iii. to evaluate the pharmacodynamic (pd) effects of krt-232 (amg-232), venetoclax and decitabine in aml blasts. iv. to determine the variability of decitabine incorporation into genomic deoxyribonucleic acid (dna) and correlate with systemic pharmacokinetics and exposure-response relationships. outline: this is a dose-escalation study of navtemadlin. patients receive decitabine intravenously (iv) over 1 hour on days 1-10, navtemadlin orally (po) once daily (qd) on days 1-7, and venetoclax po qd on days 1-21. treatment repeats every 28 days for up to 4 cycles in patients with evidence of persistent aml. starting cycle 2, patients with no morphologic evidence of aml receive decitabine iv over 1 hour on days 1-5, navtemadlin po qd on days 1-7, and venetoclax po qd on days 1-14. cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. patients also undergo bone marrow aspiration and biopsy, and blood sample collection throughout the trial. after completion of study treatment, patients are followed up for 30 days.

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 * age \>= 18 years; because no dosing or adverse event data are currently available on the use of krt-232 (amg-232) in patients \< 18 years of age, children are excluded from this study, but will be eligible for future pediatric trials * ecog performance status =\ = 60%) * white blood count =\< 25 x 10\^9/l * 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 \[sgot\])/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 * the effects of krt-232 (amg-232) on the developing human fetus are unknown;

pt/ptt must meet the inclusion criteria; subjects taking warfarin must have their inr followed closely * uncontrolled intercurrent illness including, but not limited to, active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements; patients receiving an anti-microbial agent may be eligible if the patient remains afebrile and hemodynamically stable for 72 hours; patients with myocardial infarction within 6 months of study day 1, symptomatic congestive heart failure (new york heart association \[nyha\] class iii and higher), unstable angina, or cardiac arrhythmia requiring medication are excluded * patients with gastrointestinal (gi) tract disease causing the inability to take oral medication, malabsorption syndrome, requirement for intravenous alimentation, prior surgical procedures affecting absorption, uncontrolled inflammatory gi disease (e.g., crohn's disease, ulcerative colitis) * patients with history of bleeding diathesis * positive hepatitis b surface antigen (hepbsag) (indicative of chronic hepatitis b), positive hepatitis total core antibody with negative hbsag (suggestive of occult hepatitis b), or detectable hepatitis c virus ribonucleic acid (rna) by a polymerase-chain reaction (pcr) assay (indicative of active hepatitis c - screening is generally done by hepatitis c antibody \[hepcab\], followed by hepatitis c virus rna by pcr if hepcab is positive) * human immunodeficiency virus (hiv)-patients positive for human immunodeficiency virus (hiv) are not excluded from this study, but hiv-positive patients must have: * a stable regimen of highly active anti-retroviral therapy (haart) * no requirement for concurrent antibiotics or antifungal agents for the prevention of opportunistic infections * a cd4 count above 250 cells/mcl and an undetectable hiv viral load on standard pcr-based test * men and women of reproductive potential who are unwilling to practice acceptable methods of effective birth control while on study through 5 weeks (women) or 3 months and 1 week (men) after receiving the last dose of krt-232 (amg-232); acceptable 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 iud (women) * pregnant women are excluded from this study because krt-232 (amg-232) is an agent with the potential for teratogenic or abortifacient effects; because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with krt-232 (amg-232), breastfeeding should be discontinued if the mother is treated with krt-232 (amg-232); these potential risks may also apply to other agents used in this study * patients with a baseline qtc \> 500 msec and patients with a family history of prolonged qt syndrome * patients with known tp53 mutations or chromosome 17 or 17p deletions * patients previously treated with azacytidine, decitabine, or venetoclax
