  • Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) < 2 x institutional upper limit of normal (IULN)
  • Total bilirubin < 2.0 x IULN (unless Gilbert syndrome has been diagnosed); if leukemia infiltration of the liver is suspected to be causing liver function abnormalities the patient will still be eligible with principal investigator (PI) approval
  • Creatinine < 2 x IULN
  • Creatinine clearance > 40 mL/min (measured by Cockroft-Gault)

• Females of child-bearing potential (FOCBP) must have a negative pregnancy test within 7 days of registration

    • Has not undergone a hysterectomy or bilateral oophorectomy
    • Has had menses at any time in the preceding 12 consecutive months (and therefore has not been naturally postmenopausal for > 12 months)
• Women must not be breastfeeding at the time of study registration

• Women and men of reproductive potential should agree to use two effective means of birth control

  • For women, contraception should continue for 23 weeks after the last dose of nivolumab and 12 weeks after the last dose of dasatinib to allow complete clearance of drug and its principal metabolites from the body
  • For men, contraception should continue for 31 weeks after nivolumab and 12 weeks after dasatinib
• Patients must have the ability to understand and the willingness to sign a written informed consent prior to registration on study

Exclusion Criteria:

• Patients may not be receiving any other investigational agents within 5 half-lives of the drug (if known); if the half-life is not known, investigational agents should not be taken within two weeks
• Patients are not eligible if they have an intolerance to most recent prior TKI (other than dasatinib) at the lowest possible effective dose, defined as a grade >= 3 toxicity considered at least possibly related to that TKI; patients are also excluded if they are intolerant or allergic to dasatinib and discontinued prior therapy due to a >= grade 2 treatment related adverse event
• Patients must not have a history of a grade 4 anaphylactic reaction to monoclonal antibody therapy or known hypersensitivity reactions to drugs formulated with polysorbate 90
• Patients must not have had any prior therapy with an anti-PD-1, anti-programmed cell death 1 ligand 1 (PD-L1), anti-programmed cell death 1 ligand 2 (PD-L2), anti-cluster of differentiation (CD)137 or anti-cytotoxic t-lymphocyte-associated protein 4 ligand (CTLA-4) antibody (or any antibody or drug specifically targeting T-cell costimulation or checkpoint pathways; for questions or uncertainties, please contact the PI or quality assurance manager (QAM)

• Patients who have had allogeneic hematopoietic stem cell transplant (HSCT) are not eligible if they meet any of the following:

  • transplant is within 2 months from cycle 1, day 1 (C1D1)
  • Has clinically significant graft-versus-host disease requiring treatment
  • Has >= grade 3 persistent non-hematological toxicity related to the transplant
• Concomitant use of strong inhibitors of the cytochrome p450, family 3, subfamily a, polypeptide 4 (CYP3A4) isoenzyme is not permitted; must have wash-out period of 5 times the half-life of the compound before first dasatinib dose
• Concomitant use of QT prolonging agents strongly associated with torsades de pointes is not permitted
• Patients who have a known dasatinib-resistant ABL-kinase mutation such as T315I are not eligible; for confirmation, please contact PI

• Patients who have any serious or uncontrolled medical disorder that would impair the ability of the subject to receive protocol therapy are not eligible; these include, but are not limited to:

  • Active infection that is not well controlled
  • Known pleural or pericardial effusion at baseline
  • Clinically significant gastrointestinal disease or digestive dysfunction compromising absorption of dasatinib

  • Uncontrolled or significant cardiovascular disease, including:

    • Myocardial infarction within 6 months of enrollment date
    • Uncontrolled angina or congestive heart failure within 3 months of enrollment date
    • Left ventricular ejection fraction (LVEF) < 40%

    • Significant cardiac conduction abnormality, including:

      • History of clinically significant ventricular arrhythmia (such as ventricular tachycardia, ventricular fibrillation, or torsades de pointes)
