Uproleselan, Azacitidine, and Venetoclax for the Treatment of Treatment Naive Acute Myeloid Leukemia

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 naive and eligible for venetoclax plus hypomethylating agents (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 congestive heart failure (CHF) requiring treatment or left ventricular ejection fraction (LVEF) =< 50% or chronic stable angina ** Carbon monoxide diffusing capability test (DLCO) =< 65% or forced expiratory volume in 1 second (FEV1) =< 65% ** Any other situation that the investigator judges to be incompatible with intensive chemotherapy must be reviewed with the study chair before study enrollment
• ECOG performance status of: * 0 to 2 for subjects >= 75 years of age OR * 0 to 3 for subjects 18-74 years of age
• White blood cell (WBC) =< 25,000/mm^3 at the start of study therapy (leukapheresis and hydroxyurea are allowed to meet this criteria). No other hematologic parameters
• Total bilirubin =< 1.5 x institution’s upper limit of normal (ULN) unless related to AML or Gilbert’s syndrome
• Aspartate aminotransferase (AST)/serum glutamic oxaloacetic transaminase (SGOT) and alanine aminotransferase (ALT)/serum pyruvic glutamic transaminase (SPGT) =< 3 x institutional ULN unless related to AML
• Creatinine clearance >= 45 mL/min (calculated by the Cockcroft Gault formula or measured by 24-hour urine collection) * Note, if >= 65 years of age, creatinine clearance or serum creatinine can be used for determining eligibility with creatinine clearance >= 45 mL/min (calculated by the Cockcroft Gault formula or measured by 24-hour urine collection) or serum creatinine =< institution’s ULN considered eligible
• Women of child-bearing potential and men with partners of child-bearing potential must agree to use adequate contraception (non-estrogen hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and for 90 days following completion of therapy. Should a woman or female partner of a male subject become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately * A woman of child-bearing potential is any female (regardless of sexual orientation, having undergone a tubal ligation, or remaining celibate by choice) who meets the following criteria: ** Has not undergone a hysterectomy or bilateral oophorectomy; or ** Has not been naturally postmenopausal for at least 12 consecutive months (i.e., has had menses at any time in the preceding 12 consecutive months)
• Women of child-bearing potential has negative pregnancy test prior to initiating study drug dosing
• Able to swallow and retain oral medication

Exclusion Criteria

• Current or anticipated use of other investigational agents
• Diagnosis of acute promyelocytic leukemia
• Active central nervous system involvement by AML
• AML must be treatment naive. Prior treatment with hypomethylating agent (azacitidine or decitabine), venetoclax or uproleselan, including for antecedent hematologic disorders. 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
• 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
• 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 within 3 months of starting study 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)
• History of other malignancies, except for: malignancy treated with curative intent with no known active disease present for >= 1 year; malignancies treated and in remission for 5 or more years; treated non-melanoma skin cancer; and localized, cured prostate and cervical cancer. Note: antecedent hematologic malignancies (e.g., myelodysplastic syndromes [MDS], MDS/myeloproliferative neoplasms [MPN], MPN that transformed to AML are not exclusionary.
• Evidence of uncontrolled active systemic infection requiring therapy (viral, bacterial, or fungal). Fever of unknown origin is not an exclusion criterion, as this may be disease related
• History of allergic reactions attributed to compounds of similar chemical or biologic composition to agents used in study
• Subject has a malabsorption syndrome of other condition that precludes enteral route of administration
• Subjects with a cardiovascular disability status of New York Heart Association class greater than 2
• Pregnant or nursing. There is a potential for congenital abnormalities and for this regimen to harm nursing infants.
