Overview
Brief Summary
This phase II trial evaluates the effect of azacitidine or decitabine and venetoclax in treating patients with acute myeloid leukemia that has not been treated before (treatment naive) or has come back (relapsed). Chemotherapy drugs, such as azacitidine, decitabine, and venetoclax, 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.
Detailed Description
PRIMARY OBJECTIVE: I. To evaluate the efficacy of venetoclax plus alternative hypomethylating agent (HMA), as defined by the primary endpoint of overall response rate, for patients with treatment naive acute myeloid leukemia (AML) eligible for venetoclax plus HMA with prior HMA failure. SECONDARY OBJECTIVES: I. To further examine the efficacy of venetoclax plus alternative HMA for patients with treatment naive AML eligible for venetoclax plus HMA with prior HMA failure using additional efficacy endpoints. II. To further evaluate the safety of venetoclax plus alternative HMA for patients with treatment naive AML eligible for venetoclax plus HMA with prior HMA failure.

Eligibility Criteria
Inclusion Criteria
- •Ability to understand and the willingness to sign a written informed consent
- •Diagnosis of AML by World Health Organization (WHO) 2016 criteria (Arber 2016)
- •Age \>= 18 years
- •Treatment naïve and eligible for venetoclax plus HMA: \* Age \>= 75 OR \* Age \>= 18-74 with at least one of the following co-morbidities: \*\* Eastern Cooperative Oncology Group (ECOG) performance status of 2 or 3 \*\* Cardiac history of chronic heart failure (CHF) requiring treatment or left ventricular ejection fraction (LVEF) =\< 50% or chronic unstable angina \*\* Carbon monoxide diffusing capability (DLCO) =\< 65% or forced expiratory volume in 1 second (FEV1) =\< 65% \*\* Creatinine clearance \>= 30 mL/min to =\< 45 mL/min \*\* Moderate hepatic impairment with total bilirubin \> 1.5 to =\< 3 x upper limit of normal (ULN) \*\* Any other situation that the investigator judges to be incompatible with intensive chemotherapy must be reviewed with the study chair before study enrollment
- •Patient experienced HMA failure for an antecedent hematologic disorder (e.g. myelodysplastic syndrome) prior to study entry (Santini 2019), defined as: \* Disease progression or stable disease as best response to \>= 4 cycles of HMA or \>= 2 cycles of HMA combination therapy (primary resistance) OR \* Relapse or progression after prior response to HMA (secondary resistance)
- •Prior decitabine and/or azacitidine, including oral formulations, for antecedent hematologic disorder is required. The patient should be treatment naïve for the AML diagnosis
- •Prior allogeneic hematopoietic transplant for antecedent hematologic disorder is allowed if done at least 3 months prior to enrollment and there is no evidence of active graft versus host disease (GVHD) or requirement for systemic immune suppression
- •ECOG performance status of: \* 0 to 2 for subjects \>= 75 years of age OR \* 0 to 3 for subjects \>= 18-74 years of age
- •Whole blood cell (WBC) \>= 25,000/mm\^3 at the start of study therapy (leukapheresis and hydroxyurea areallowed to meet this criteria)
- •Total bilirubin =, 1.5 x institution's ULN unless related to AML or Gilbert's syndrome (subjects who are \>= 18-74 may have a total bilirubin of =\< 3 x institution's ULN)
Exclusion Criteria
- •Current or anticipated use of other investigational agents within 14 days or 5 half-lives (whichever is shorter) prior to the first dose and throughout venetoclax administration
- •Diagnosis of acute promyelocytic leukemia
- •Active central nervous system involvement by AML
- •Anticancer therapies, including investigational therapy, chemotherapy, targeted small molecule agents, or radiotherapy within 14 days or 5 half-lives (whichever is shorter) prior to the first dose and throughout venetoclax administration. Biologic agents (e.g. monoclonal antibodies) given for anti-neoplastic intent within 30 days prior to the first dose and throughout venetoclax administration
- •Prior therapy with venetoclax
- •Known diagnosis of human immunodeficiency virus (HIV) infection or known active hepatitis A, B or C infection with the exception of those with an undetectable viral load and CD4+ T-cell (CD4+) counts \>= 350 cells/μL within 3 months of starting study treatment. Should have no titers within 28d of day
- •Patients with hepatitis C virus (HCV) infection should have completed curative antiviral treatment
- •Known strong and/or moderate CYP3A inducers within 7 days prior to the initiation of study treatment
- •Subject has consumed grapefruit, grapefruit products, Seville oranges or starfruit within 3 days prior to the initiation of study treatment
- •Severe or uncontrolled medical disorder that would, in the investigator's opinion, impair ability to receive study treatment (i.e., uncontrolled diabetes, chronic renal disease, chronic pulmonary disease or active, uncontrolled infection, psychiatric illness/social situations that would limit compliance with study requirements)
Arms & Interventions
Treatment (azacitidine, decitabine, venetoclax)
Patients receive azacitidine IV over 10-40 minutes or SC on days 1-7 (for patients with prior decitabine use), or decitabine IV on days 1-5 (for patients with prior azacitidine), and venetoclax PO daily on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
Intervention: Azacitidine
Treatment (azacitidine, decitabine, venetoclax)
Patients receive azacitidine IV over 10-40 minutes or SC on days 1-7 (for patients with prior decitabine use), or decitabine IV on days 1-5 (for patients with prior azacitidine), and venetoclax PO daily on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
Intervention: Decitabine
Treatment (azacitidine, decitabine, venetoclax)
Patients receive azacitidine IV over 10-40 minutes or SC on days 1-7 (for patients with prior decitabine use), or decitabine IV on days 1-5 (for patients with prior azacitidine), and venetoclax PO daily on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
