PRIMARY OBJECTIVE:
I. To determine the overall response rate (ORR) of venetoclax in combination with 10-day decitabine in patients with refractory/relapsed acute myeloid leukemia (AML); elderly (> 60 year old) patients with newly diagnosed AML not eligible for intensive chemotherapy; patients with high-risk myelodysplastic syndrome (MDS) with bone marrow blasts between 10% and 20%, relapsed or refractory to prior hypomethylating agent (HMA) therapy, or chronic myelomonocytic leukemia (CMML) with bone marrow blasts >= 10% regardless of prior therapy; AML patients with prior history of MDS or CMML who received therapy for the MDS or CMML and progressed to AML, and younger patients with newly diagnosed AML with poor risk complex karyotype and/or TP53 deletions/mutations and patients with blastic plasmacytoid dentritic cell neoplasm (BPDCN).
SECONDARY OBJECTIVES:
I. To determine the duration of response, disease-free survival (DFS), and overall survival (OS) of patients with refractory/relapsed AML treated with this combination.
II. To determine the number of patients who achieve a hematologic improvement (HI) in platelets, hemoglobin, or absolute neutrophil count (ANC) and the number of patients who achieve > 50% reduction in blasts on therapy with venetoclax/10-day decitabine.
III. To determine the safety of venetoclax in combination with 10-day decitabine in patients with refractory/relapsed AML.
IV. To determine the number of patients who transition towards stem cell transplantation upon achieving response with the combination venetoclax/10-day decitabine regimen.
V. To determine the incidence of infectious complications per cycle with venetoclax in combination with 10-day decitabine.
EXPLORATORY OBJECTIVES:
I. To investigate possible relationships between baseline protein and gene expression signatures/mutation profile and BH3 profiling in predicting clinical response to the combination.
II. To characterize the pharmacokinetic (PK) profiles of venetoclax in combination with decitabine and antifungals in plasma samples.
OUTLINE:
Participants receive decitabine intravenously (IV) over 1 hour on days 1-10 and may also receive decitabine on days 1-5 after achieving complete remission/complete remission with incomplete count recovery during consolidation/maintenance. Participants also receive venetoclax orally (PO) daily on days 1-28 of cycle 1 and on days 1-21 of subsequent cycles. Treatment repeat every 28 days for up to 24 cycles in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, participants are followed up every 3 to 6 months for up to 5 years.

Experimental: Treatment (decitabine, venetoclax)
Participants receive decitabine IV over 1 hour on days 1-10 and may also receive decitabine on days 1-5 after achieving complete remission/complete remission with incomplete count recovery during consolidation/maintenance. Participants also receive venetoclax PO daily on days 1-28 of cycle 1 and on days 1-21 of subsequent cycles. Treatment repeat every 28 days for up to 24 cycles in the absence of disease progression or unacceptable toxicity.

- Overall response rate (ORR) [ Time Frame: Up to 4 cycles (112 days) ]Will be defined as the proportion of patients who had CR (complete remission), CRp (complete remission with incomplete platelet recovery), CRi (complete remission with incomplete count recovery), PR (partial response) or marrow clearance of blasts within 3 months of treatment initiation among adult patients with acute myeloid leukemia (AML); and complete remission (CR), partial remission (PR) or marrow CR (mCR) lasting at least 4 weeks for patients with myelodysplastic syndrome (MDS). Descriptive statistics including plots, mean, median and standard deviations will be used to summarize data. Will estimate the ORR for the combination treatment, along with the 95% confidence interval. The association between ORR and patient's clinical characteristics will be examined by Wilcoxon's rank sum test or Fisher's exact test, as appropriate.
- Incidence of adverse events [ Time Frame: Up to 5 years ]Toxicity type, severity and attribution will be summarized for each patient using frequency tables.
- Duration of response [ Time Frame: Up to 5 years ]Will be estimated using the method of Kaplan-Meier. Comparisons of time-to-event endpoints by important subgroups will be made using the log rank tests.
- Disease free survival [ Time Frame: Up to 5 years ]Will be estimated using the method of Kaplan-Meier. Comparisons of time-to-event endpoints by important subgroups will be made using the log rank tests.
- Overall survival [ Time Frame: Up to 5 years ]Will be estimated using the method of Kaplan-Meier. Comparisons of time-to-event endpoints by important subgroups will be made using the log rank tests.
- Biomarker analysis [ Time Frame: Baseline ]Baseline protein, gene expression signatures/mutation profile and BH3 profiling will be summarized with descriptive statistics. The correlation with endpoints of anti tumor activity will be explored where possible.
