Eligibility |
Inclusion Criteria:
- Newly diagnosed and pathologically-confirmed, previously untreated AML as defined by
World Health Organization (WHO) criteria. Bone marrow biopsy, or aspirate or
peripheral blood that were obtained up to 3 weeks before signing consent are allowed
for purposes of confirming AML diagnosis for eligibility purposes. Secondary AML
arising from prior myelodysplastic syndrome (MDS), as long as they have not received
more than full cycle of hypomethylating agent therapy for MDS, and therapy related
(t)-AML are also allowed. AML arising from prior antecedent hematologic disorders
defined as MDS, myeloproliferative neoplasm (MPN), or aplastic anemia are allowed.
Note 1: Patients must have evidence of bone marrow involvement on aspirate or biopsy.
Patients with only extramedullary disease and no bone marrow involvement will be
excluded. Note 2: Every effort should be made to get an aspirate for central flow
assessment at screening and all subsequent required time points, but in cases where an
aspirate cannot be collected-including dry taps-the patient will not be excluded and
assessments will be performed on peripheral blood (PB) which should be collected at
every time that bone marrow (BM) is collected. Note 3: Some patients with AML require
initiation of therapy quickly after diagnosis, and full metaphase karyotype results in
some centers can take 2-3 weeks to result. To avoid this issue being an impediment to
accrual to study or to cause delays in initiation of therapy in patients who need fast
initiation of therapy, we allow use of karyotype and/or fluorescence in situ
hybridization (FISH) results on samples from blood or marrow that were obtained up to
3 weeks before signing consent for purposes of eligibility and stratification. In any
case, results from FISH or karyotype should exclude presence of core-binding factor
(CBF) abnormalities by time of randomization
- Age >= 60 years
- Patients who are ineligible for intensive chemotherapy according to treating
physician's assessment or who refuse intensive chemotherapy
- Eastern Cooperative Oncology Group (ECOG) performance status of 0-3
- Prior use of lenalidomide, erythropoiesis-stimulating agents (ESAs), and growth
factors is allowed if used to treat prior MDS. AML must be previously untreated except
for hydroxyurea, or all-trans retinoic acid (ATRA) for suspicion of APL but both
should be discontinued prior to initiation of study therapy. Hypomethylating agents
are not allowed to have been used for AML therapy. If hypomethylating agent therapy
was used for prior MDS or MPN therapy then it should not have exceeded one full cycle.
Note: One dose of prophylactic intrathecal therapy is allowed during or before
screening if a lumbar puncture is performed to rule out central nervous system (CNS)
involvement
- Hydroxyurea or leukopheresis are allowed for management of hyperleukocytosis, as well
as ATRA, before initiation of study therapy. White blood cell (WBC) count must be < 25
x 10^9/L to start on study therapy per venetoclax label. Hydroxyurea and ATRA may be
administered up to one day prior to start of study treatment
- Intermediate-risk or poor risk AML as well as favorable risk by National Comprehensive
Cancer Network (NCCN)/European LeukemiaNet (ELN) with the exception of "good-risk"
cytogenic profile (i.e., for eligibility patient should lack the presence of t(8;21),
(inv[16] or t[16;16]), or t(15;17) by full cytogenetics or FISH). Clarification: We
allow use of karyotype and/or FISH results (as well as FLT3 results) on samples from
blood or marrow that were obtained up to 3 weeks before signing consent for purposes
of eligibility and stratification. Adverse karyotype can be determined based on FISH
results (e.g., loss of chromosome 7 or 5 or 3 or more abnormalities) based on the
specific probes used in the FISH. If results of full metaphase karyotype are not
available and the available FISH results do not suggest an adverse karyotype, and
there is a need to initiate therapy before those full results are available, then the
patient can be stratified into the unknown/intermediate NCCN cytogenetic group for
randomization purposes. In any case, results from FISH or karyotype should show that
core-binding factor (CBF) abnormalities are NOT present by at time of randomization as
the presence of CBF abnormalities is an exclusion factor
- Creatinine =< 1.5 x upper limit of normal (ULN) OR measured or calculated creatinine
clearance (CrCl) >= 60 mL/min for patient with creatinine levels > 1.5 x institutional
ULN
- Creatinine clearance (CrCl) should be calculated per institutional standard
- Glomerular filtration rate (GFR) can also be used in place of creatinine or CrCl
- Total bilirubin =< 1.5 x ULN OR direct bilirubin =< ULN for patients with total
bilirubin levels > 1.5 x ULN

meet the following eligibility requirements:
- They must be stable on their anti-retroviral regimen, and they must be healthy
from an HIV perspective
- Patients must have an undetectable HIV viral load
- Patients with a known history of hepatitis C virus (HCV) infection must have been
treated and cured. For patients with HCV infection who are currently on treatment,
they are eligible if they have an undetectable HCV viral load. For patients with
evidence of chronic hepatitis B virus (HBV) infection, the HBV viral load must be
undetectable on suppressive therapy, if indicated
- Patients who have undergone major surgery must have recovered adequately from the
toxicity and/or complications from the intervention prior to starting therapy
- Female patients of childbearing potential must have a negative urine or serum
pregnancy test within 72 hours prior to receiving the first dose of study medication.
If the urine test is positive or cannot be confirmed as negative, a serum pregnancy
test will be required. A female of childbearing potential is any woman, regardless of
sexual orientation or whether they have undergone tubal ligation, who meets the
following criteria: 1) has not undergone a hysterectomy or bilateral oophorectomy; or
2) has not been naturally postmenopausal for at least 24 consecutive months (i.e., has
had menses at any time in the preceding 24 consecutive months). Female patients of
childbearing potential must be willing to use an adequate method of contraception for
the course of the study through 120 days after the last dose of study medication. Male
patients who have a female partner of childbearing potential must agree to use an
adequate method of contraception, starting with the first dose of study therapy
through 120 days after the last dose of study therapy. NOTE: Abstinence is acceptable
if this is the usual lifestyle and preferred contraception for the patient
- Ability to understand and the willingness to sign a written informed consent document.
Participants with impaired decision-making capacity (IDMC) who have a
legally-authorized representative (LAR) and/or family member available will also be
eligible
Exclusion Criteria:

multi-gated acquisition (MUGA)
- Patients who have not recovered from AEs due to prior anti-cancer therapy (i.e., have
residual toxicities > grade 1) with the exception of =< grade 2 neuropathy and
alopecia
- NOTE: Participants must have recovered from all radiation-related toxicities, not
require corticosteroids, and not have had radiation pneumonitis. A 1-week washout
is permitted for palliative radiation (=< 2 weeks of radiotherapy) to non-CNS

other agents used in this study
- Current use of systemic corticosteroids or immunosuppressive agents
- EXCEPTION: Low doses of steroids (< 10 mg of prednisone or equivalent dose of
other steroid), used for treatment of non-hematologic medical condition (e.g.,
chronic adrenal insufficiency) inhaled corticosteroids, or topical steroids are
permitted
- Other active primary malignancy (other than non-melanomatous skin cancer or carcinoma
in situ of the cervix) requiring treatment or limiting expected survival to =< 2 years
- NOTE: If there is a history of prior malignancy, they must not be receiving other
specific treatment (other than hormonal therapy for their cancer)
- Patient with known active CNS disease and/or carcinomatous meningitis before study
enrollment. Assessment of the cerebrospinal fluid (CSF) is not required to enroll in
the study unless there is clinical suspicion for CNS involvement. However, if CSF
assessment is performed for any reason, there should be no evidence of active leukemia
in the CSF as per investigator judgement. Up to one dose of prophylactic intrathecal
chemotherapy is allowed prior to study enrollment. Subjects with previously treated
brain metastases may participate provided they are stable (without evidence of
progression by imaging for at least four weeks prior to the first dose of protocol
treatment and any neurologic symptoms have returned to baseline), have no evidence of
new or enlarging brain metastases, and are not using steroids for at least 7 days
prior to protocol treatment. This exception does not include carcinomatous meningitis
which is excluded regardless of clinical stability
- Patients who received prior allogenic transplant
- Patient with a history or current evidence of any condition, therapy, or laboratory
abnormality that might confound the results of the trial, interfere with the subject's
participation for the full duration of the trial, or is not in the best interest of
the subject to participate, in the opinion of the treating investigator
- Patient with a diagnosis of immunodeficiency or receiving high dose systemic steroid
therapy or any other form of immunosuppressive therapy within 7 days prior to the
first dose of treatment
- Patient with active autoimmune disease except for patients with hypothyroidism and
vitiligo that has required systemic treatment in the past 2 years (i.e., with use of
disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement
therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy
for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic
treatment

steroids or current non-infectious pneumonitis
- Patient with active uncontrolled infection
- Patient with a known history of active TB (Bacillus tuberculosis)
- Patients with uncontrolled intercurrent illness
- Patients with psychiatric illness/social situations that would limit compliance with
study requirements
- Pregnant women are excluded from this study because pembrolizumab (MK-3475) is
humanized antibody 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 pembrolizumab, breastfeeding should be
discontinued if the mother is treated with pembrolizumab. These potential risks may
also apply to other agents used in this study
- Patients with no bone marrow involvement (i.e., those with only extramedullary
disease)
- Patients who received prior hypomethylating agent (HMA) therapy for more than one full
cycle in treatment for prior MDS. Patient must not have received HMA therapy for
treatment of AML
- Patients that received a live vaccine within 30 days of planned start of study therapy
- NOTE: Seasonal influenza vaccines for injection are generally inactivated flu
vaccines and are allowed; however intranasal influenza vaccines (e.g., Flu-Mist
[registered trademark]) are live attenuated vaccines, and are not allowed
- Patients with active hemolytic anemia requiring immunosuppressive therapy or other
pharmacologic treatment. Patients who have a positive Coombs test but no evidence of
hemolysis are NOT excluded from participation
