| Eligibility |
Inclusion Criteria:
1. Pediatric Participants with Relapsed/refractory AML by WHO criteria.
2. Participants must have = 5% blasts in the bone marrow as assessed by morphology or
flow cytometry. However, if an adequate bone marrow sample cannot be obtained,
participants may be enrolled if there is unequivocal evidence of leukemia with = 5%
blasts in the peripheral blood or an AML defining genetic abnormality as specified by
the WHO 2022 criteria.
3. Performance status: Lansky = 50 for participants who are = 16 years old and Karnofsky
= 50% for participants who are > 16 years old.
4. Age =2 years of age and =18 years of age
5. Able to swallow pills
6. The following baseline laboratory data:
1. Total serum bilirubin =1.5 x upper limit of normal (ULN) for age. Participants
with known Gilbert's syndrome may have a total bilirubin up to =5 x ULN for age.
2. Creatinine clearance (Schwartz-Formula) or radioisotope GFR = 60ml/min/1.73 m2 or
a serum creatinine based on age/sex as follows:
3. Alanine aminotransferase (ALT) and/or aspartate aminotransferase (AST) =3 x ULN;
=5 x ULN in case of suspected leukemic liver involvement.
4. Females of childbearing potential must have a negative serum or urine beta human
chorionic gonadotropin (ß-HCG) pregnancy test result within 14 days prior to the
first dose of study drugs and must agree to use one of the following effective
contraception methods during the study and for 6 months following the last dose
of study drug. Effective methods of birth control include:
i. Birth control pills, skin patches, shots, implants (placed under the skin by a
health care provider) ii. Intrauterine devices (IUDs) iii. Condom or occlusive cap
(diaphragm or cervical/vault caps) used with Spermicide iv. Abstinence e. Males, need
to inform the doctor right away if the partner becomes pregnant or suspects pregnancy.
While in this study and for 3 months after the last treatment the patient should not
donate sperm for the purposes of reproduction. He will need to use a condom while in
this study and for 3 months after the last treatment.
7. At least one parents or LAR must provide signature of informed consent and there must
be documentation of assent by the subject, as age appropriate, before completing any
study-related procedures.
Exclusion Criteria:
1. Concomitant other anti-cancer therapy and/or participation in any other
investigational clinical trials except for hydroxyurea. Concurrent hydroxyurea use
should be limited to the first 2 cycles of therapy only.
2. History of another primary invasive malignancy that has not been definitively treated
and is in remission. Participants with non-melanoma skin cancers or with carcinomas in
situ are eligible regardless of the time from diagnosis (including concomitant
diagnoses).
3. Presence of clinically significant uncontrolled central nervous system (CNS) pathology
such as epilepsy, childhood seizure, paresis, aphasia, stroke, severe brain injuries,
organic brain syndrome, or psychosis.
4. Evidence of active cerebral/meningeal disease. Participants may have history of CNS
leukemic involvement if definitively treated with prior therapy and no evidence of
active disease at the time of consent with at least 2 consecutive spinal fluid
negative assessments for residual leukemia and negative imaging (imaging required only
if previously showing evidence of CNS leukemia not otherwise documented by spinal
fluid assessment).
5. Participants with uncontrolled, active infections (viral, bacterial, or fungal) or
other disease expected to interfere with the ability of the PI to assess the efficacy
of the study drug. Infections controlled on concurrent anti-microbial agents are
acceptable, and anti-microbial prophylaxis per institutional guidelines are
acceptable.
6. Known active hepatitis B (eg, HBsAg reactive), or hepatitis C (eg, HCV RNA
[qualitative] is detected), or chronic hepatitis B or C infection or human
immunodeficiency virus (HIV) infection in medical history, with the following
exceptions:
a. Those with a history of hepatitis with a negative polymerase chain reaction (either
qualitative or quantitative) OR have documentation of stable disease with aspartate
aminotransferase (AST)/serum glutamic oxaloacetic transaminase and alanine
aminotransferase (ALT)/serum glutamic pyruvic transaminase <2.0×upper limit of normal
(ULN) may be eligible for this study.
b) Subjects with history of HIV who have an undetectable viral load for the prior 3
months, and who agree to maintain antiviral therapy, may be eligible for the study.
7. Liver cirrhosis or other serious active liver disease or with suspected active alcohol
abuse.
8. Exclude participants with active GVHD and those on immunosuppressive drugs for
treatment of GVHD. Require that participants be off calcineurin inhibitors for at
least 4 weeks to be eligible.
9. Prior chemotherapy/radiotherapy/investigational therapy within 2 weeks before the
start of study drugs with the following exception:
a. To reduce the circulating blast count or palliation: intravenous cytarabine,
steroids or hydroxyurea. No washout necessary for these agents.
10. Females who are pregnant or lactating.
11. Male or female subjects of childbearing potential, unwilling to use an approved,
effective means of contraception.
12. Other severe, uncontrolled acute or chronic medical or psychiatric condition or
laboratory abnormality that in the opinion of the Investigator may increase the risk
associated with study participation or investigational product administration or may
interfere with the interpretation of study results and/or would make the participant
inappropriate for enrollment into this study.
13. Participants with acute promyelocytic leukemia, juvenile myelomonocytic leukemia, or
bone marrow failure syndromes are not eligible.
14. Known or suspected hypersensitivity to decitabine, cedazuridine, or venetoclax.
15. Participants on concomitant medications known to be metabolized by CDA will need
review of the medication and assessment of possible impact of avoiding dosing during
the 24 hours prior to possible enrollment, at the time of cedazuridine exposure, and
24 hours following the last dose of oral decitabine/cedazuridine.
16. Participants of adult age (= 18 years of age) who are cognitively impaired will not be
eligible for this study.
