DS-1594b With or Without Azacitidine, Venetoclax, or Mini-HCVD for the Treatment of Relapsed or Refractory Acute Myeloid Leukemia or Acute Lymphoblastic Leukemia
An Open-Label Phase 1/2 Multi-Arm Study of DS-1594b as a Single-Agent and in Combination With Azacitidine and Venetoclax or Mini-HCVD for the Treatment of Patients With Acute Myeloid Leukemia (AML) and Acute Lymphoblastic Leukemia (ALL)

Brief Summary
This phase I/II trial studies the effect of DS-1594b with or without azacitidine, venetoclax, or mini-HCVD in treating patients with acute myeloid leukemia or acute lymphoblastic leukemia that has come back (recurrent) or not responded to treatment (refractory). Chemotherapy drugs, such as azacitidine, venetoclax, and mini-HCVD, 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. DS-1594b may inhibit specific protein bindings that cause blood cancer. Giving DS-1594b, azacitidine, and venetoclax, or mini-HCVD may work better in treating patients with acute myeloid leukemia or acute lymphoblastic leukemia.

Eligibility Criteria
You may qualify if:
- Provision of written (signed) informed consent form (ICF) by the subject or legal guardian prior to the performance of any study-specific procedures, according to International Council on Harmonisation (ICH) and local regulatory requirements. Subject must be fully informed about their illness and the investigational nature of the study protocol (including foreseeable risks and possible toxicities) and must sign and date an Institutional Review Board (IRB)/Independent Ethics Committee (IEC) approved informed consent form (ICF)(including Health Insurance Portability and Accountability Act authorization \[HIPAA\], if applicable) before performance of any study-specific procedures or examinations
- Subjects must be willing and able to comply with the protocol
- Subjects with AML or ALL, diagnosed according to the 2016 criteria by the World Health Organization (WHO) who are refractory or relapsed (any salvage) with no available therapies or not candidates for available therapies. For subjects with prior MDS or chronic myelomonocytic leukemia (CMML) or MPN who transformed to AML, therapy received for MDS, CMML, or MPN is NOT considered as prior therapy for AML except for MDS or CMML treated with HMAs. Subjects with MDS or CMML treated with HMA therapies who progress to AML and have no available therapies or are not candidates for available therapies, will be eligible at the time of progression to AML. In Phase 1: all R/R AML or R/R ALL subjects irrespective of mutations will be eligible. In Phase 2 Cohort A only R/R AML with MLLr will be eligible. In Phase 2 Cohort B only R/R AML with NPM1m will be eligible. In Phase 2 Cohorts C and D: Only R/R AML or R/R ALL subjects with an MLLr or NPM1m will be eligible
- Prior therapy with hydroxyurea, chemotherapy, biological or targeted therapy (e.g. FLT3 inhibitors, other kinase inhibitors), or hematopoietic growth factors is permitted
- Age 18 years or older
- Eastern Cooperative Oncology Group (ECOG) performance status 0, 1, or 2
- Total bilirubin =\< 1.5 times upper limit of normal (x ULN)
- Aspartate aminotransferase or alanine aminotransferase =\< 2.5 x ULN (aspartate aminotransferase or alanine aminotransferase =\< 5.0 x ULN if deemed related to leukemia by the treating physician)
- Creatinine clearance \>= 50 mL/min as calculated using the modified Cockcroft-Gault equation
- Serum electrolytes within the institution's normal limits: potassium, calcium (total calcium, calcium corrected for serum albumin in case of hypoalbuminemia or ionized calcium) and magnesium. If outside of the institution's normal range, subject will be eligible when electrolytes are corrected
- In the absence of rapidly progressive disease, the interval from prior treatment to the time of initiation of protocol therapy will be at least 14 days for prior anti-leukemic therapy with the exception of hydroxyurea as noted below OR at least 5 half-lives for cytotoxic/noncytotoxic agents, whichever is shorter. The half-life for the therapy in question will be based on published pharmacokinetic literature (abstracts, manuscripts, investigator brochure's, or drug-administration manuals) and will be documented in the protocol eligibility document. Since the effect of therapy may be delayed, use of hydroxyurea for subjects with rapidly proliferative disease is allowed before the start of study therapy and on study and hydroxyurea will not require a washout
- Concurrent therapy for central nervous system (CNS) prophylaxis or continuation of therapy for controlled CNS disease is permitted. Subjects with a known history of CNS disease or leukemic brain metastasis must have been treated locally, have at least 3 consecutive lumbar punctures (LPs) with no evidence of CNS leukemia, and must be clinically stable for at least 4 weeks prior to enrollment and have no ongoing neurological symptoms that in the opinion of the treating physician are related to the CNS disease (sequelae that are a consequence of the treatment of the CNS disease are acceptable)
- Females must be surgically or biologically sterile or postmenopausal (amenorrheic for at least 12 months) or if of childbearing potential, must have a negative serum or urine pregnancy test within 72 hours before the start of the treatment
- Women of childbearing potential must agree to use an adequate method of contraception during the study and until 4 months after the last treatment. Males must be surgically or biologically sterile or agree to use an adequate method of contraception during the study until 3 months after the last treatment. Adequate methods of contraception include:
- Total abstinence when this is in line with the preferred and usual lifestyle of the subject. Periodic abstinence (e.g., calendar, ovulation, symptothermal, postovulation methods) and withdrawal are not acceptable methods of contraception.
- +8 more criteria
You may not qualify if:
- Subjects with a known allergy, hypersensitivity, or contraindication to the protocol therapies or any of their components to be used in the arm the subject is to be enrolled on
- Uncontrolled or significant cardiovascular disease, including any of the following:
- Bradycardia of less than 50 beats per minute, unless the subject has a pacemaker;
- Corrected QT interval Fridericia's Correction Formula (QTcF) interval \> 450 msec;
- Diagnosis of or suspicion of long QT syndrome (including family history of long QT syndrome);
- Systolic blood pressure \>=180 mmHg or diastolic blood pressure \>=110 mmHg;
- History of clinically relevant ventricular arrhythmias within 6 months prior to screening (eg, ventricular tachycardia, ventricular fibrillation, or Torsade de Pointes);
- History of second (Mobitz II) or third-degree heart block (subjects with pacemakers are eligible if they have no history of fainting or clinically relevant arrhythmias while using the pacemaker);
- History of uncontrolled angina pectoris, unstable angina or myocardial infarction, coronary artery bypass graft (CABG), cerebrovascular accident (CVA), transient ischemia attack (TIA), symptomatic pulmonary emboli within 6 months prior to screening;
- New York Heart Association Class 3 or 4 heart failure;
- Left ventricular ejection fraction (LVEF) =\< 50 or less than the institutional lower limit of normal;
- Complete left bundle branch block (right bundle branch block is permitted, but requires manual reading of the QTc interval);
- Active cardiac dysrhythmias of National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) grade \>= 2 (eg, atrial fibrillation)
- Persisting toxicity related to prior therapy of grade \> 1 NCI-CTCAE v 5.0; however, alopecia and sensory neuropathy grade 2 or lower is acceptable
- Underwent HSCT within 90 days of the first dose of protocol therapy, or subjects with clinically significant (grade 2 or greater) graft-versus-host disease (GVHD) (the use of topical steroids for ongoing cutaneous GVHD is permitted)
