Detailed Description
PRIMARY OBJECTIVES:
I. Determine the maximum tolerated dose (MTD) and/or a recommended phase II dose (RP2D) of venetoclax in combination with dasatinib.
II. Evaluate the safety of venetoclax in combination with dasatinib by assessing the frequency, type, and severity of adverse events.
SECONDARY OBJECTIVES:
I. Assess preliminary response to venetoclax in combination with dasatinib based on minimal residual disease (MRD) negativity.
II. Estimate progression-free and overall survival.
EXPLORATORY OBJECTIVES:
I. Evaluate the distribution of BCR-ABL fusion sub-types. II. Assess changes in BCL-family dependence. III. Presence of co-occurring leukemia-specific mutations. IV. Assess ex vivo sensitivity to venetoclax and dasatinib using inhibitor plates and colorimetric cell viability (MTS) assay.
OUTLINE: This is dose-escalation study of venetoclax.
INDUCTION PHASE CYCLE 1: Patients receive prednisone orally (PO) once daily (QD) on days -6 to 21 and rapid taper from days 22-28, dasatinib PO QD days 1-28, venetoclax PO QD days 3-28 or days 3-21, rituximab (for CD20+ patients) intravenously (IV) on days 8 and 15, and methotrexate intrathecally (IT) once during week 1 and once during week 3 in the absence of disease progression or unacceptable toxicity.
INDUCTION PHASE CYCLES 2-3: Patients receive dasatinib PO QD days 1-28, venetoclax PO QD on days 1-28 or 1-21, rituximab (for CD20+ patients) IV on days 1 and 15, and methotrexate IT on days 1 and 15. Treatment repeat every 28 days for up to 2 cycles in the absence of disease progression or unacceptable toxicity. Patients with clinical benefit may continue to receive treatment for up to 12 months per the discretion of the physician.
CONSOLIDATION CYCLES 4 AND 5 (ALL PATIENTS ONLY): Patients receive blinatumomab IV on days 1-28. Cycles repeat every 42 days in the absence of disease progression or unacceptable toxicity. Patients continue to receive dasatinib PO QD and venetoclax PO QD as taken in cycles 1-3 and, if clinically indicated, methotrexate IT on days 1 and 15. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients undergo bone marrow biopsy and aspiration, lumbar puncture, and blood sample collection throughout the study
After completion of study treatment, patients are followed up at 4 weeks and then every 12 weeks for up to 1 year.

- Persons of reproductive potential must agree to use a highly effective method of contraception throughout treatment and for at least 4 weeks after study drug is stopped. Persons of childbearing potential and persons with a sexual partner of childbearing potential must be advised of the importance of avoiding pregnancy during trial participation and the potential risk factors for an unintentional pregnancy
- Normal corrected QT Formula (QTcF) interval on screening electrocardiogram (EKG) (< 450 ms in men, < 470 ms in women)
- Ability to understand and the willingness to sign a written informed consent document
Exclusion Criteria:
- For newly diagnosed subjects: who have received treatment with cytotoxic chemotherapy, radiotherapy or immunotherapy for their ALL/MPAL, or prior dasatinib treatment. For relapsed subjects: prior dasatinib treatment (however treatment with other tyrosine kinase inhibitors [TKIs] is permitted)
- Subjects who have received any investigational agents or subjects who are taking investigational or commercial agents or therapies with the intent to treat the subject's malignancy within seven days or three half-lives of enrollment (i.e. initiation of dasatinib)
- Subjects with chronic myelogenous leukemia (CML) in myeloid blast crisis, Ph+ acute myeloid leukemia (AML) or acute leukemia lineage that cannot be classified based on existing criteria (e.g., from the World Health Organization [WHO] or International Consensus Classification [ICC])
- Subjects with clinically serious infections as determined by the provider requiring ongoing antibiotic therapy. This does not include antibiotic treatment for neutropenic fever
- Individuals with a pleural or pericardial effusion of any grade
- Subjects with a history of allergic reactions attributed to compounds of similar chemical or biologic composition to dasatinib or other agents used in the study
- Subjects who have undergone stem cell transplant must be at least 100 days after transplant, and without active treatment for graft versus host disease (GVHD) other than topical medications
- Subjects with uncontrolled cardiac illness including but not limited to, symptomatic congestive heart failure, unstable angina pectoris, clinically significant ventricular arrhythmias (such as ventricular tachycardia, ventricular fibrillation, or Torsades de pointes), or pulmonary hypertension
- Subjects with diagnosed congenital prolonged QT syndrome
- Pregnant persons are excluded from this study because dasatinib is a pregnancy category D agent 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 dasatinib, breastfeeding should be discontinued if the mother is treated with dasatinib. These potential risks may also apply to venetoclax for which the pregnancy category and risks to the fetus are unknown
Participant is seropositive with human immunodeficiency virus (HIV) or has active infection with hepatitis B virus (HBV) or hepatitis C virus (HCV).
- HIV-infected individuals on effective anti-retroviral therapy with undetectable viral load within 6 months are eligible for this trial.
- For individuals with evidence of chronic HBV infection, the HBV viral load must be undetectable on suppressive therapy, if indicated.
- Individuals with a history of HCV infection must have been treated and cured. For individuals with HCV infection who are currently on treatment, they are eligible if they have an undetectable HCV viral load
- Subjects with invasive malignancy over the previous year except treated early stage carcinomas of the skin, completely resected intraepithelial carcinoma of the cervix, completely resected papillary thyroid and follicular thyroid cancers, and localized prostate cancer treated with curative intent with surgery or radiation
- Subjects with any gastrointestinal condition which would lead to inability to absorb an oral medication

A dose-limiting toxicity (DLT) is defined as an adverse event or abnormal laboratory value assessed as unrelated to disease, disease progression, inter-current illness, or concomitant medications.
In order to be declared a dose-limiting toxicity, an adverse experience must be determined related (definitely, probably, or possibly) to study drug.
Point estimates and 95% exact confidence intervals will be reported for all patients in the safety set as well as in subgroups defined by whether or not a patient received blinatumomab consolidation therapy.
