Brief Summary
This phase I trial studies the side effects and best dose of recombinant EphB4-HSA fusion protein when given together with cytarabine or vincristine liposomal in treating participants with acute leukemia that has come back or has not responded to treatment. Drugs used in chemotherapy, such as recombinant ephb4-HSA fusion protein, cytarabine, and vincristine liposomal, 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. Giving the drugs in different combinations may kill more cancer cells.

Outcome Measures
Primary Outcomes (3)
Incidence of adverse events
Will be assessed by Common Terminology Criteria for Adverse Events (CTCAE) v4.03 and summarized for each course separately.
Up to 24 months
Best clinical response in the blood and bone marrow observed at anytime during single agent treatment with recombinant EphB4-HSA fusion protein alone
Best clinical response defined as complete remission (CR) + complete remission with incomplete blood count recovery (CRi) + partial remission (PR) + partial remission with incomplete blood count recovery (PRi). CR defined as Neutrophils: \>1,000/µL; Platelets: \>100,000/µL; Bone Marrow Blasts: \<5% with spicules, no Auer rods; Other: Transfusion independent, no extra medullary disease. CRi defined as Neutrophils: \<1,000/µL; Platelets: \<100,000/µL; Bone Marrow Blasts: \<5%; Other: Either neutrophils or platelets not recovered, no extra medullary disease. PR defined as Neutrophils: \>1,000/µL; Platelets: \>100,000/µL; Bone Marrow Blasts: decrease to 5-25 and = \> 50% decrease from start. PRi defined as Neutrophils: \<1,000/µL; Platelets: \<100,000/µL; Bone Marrow Blasts: decrease to 5-25 and = \> 50% decrease from start.
Up to 24 months
Complete remission (CR) and complete remission with incomplete blood count recovery (CRi) observed at anytime for the combination with cytarabine or liposomal vincristine
CR defined as Neutrophils: \>1,000/µL; Platelets: \>100,000/µL; Bone Marrow Blasts: \<5% with spicules, no Auer rods; Other: Transfusion independent, no extra medullary disease. CRi defined as Neutrophils: \<1,000/µL; Platelets: \<100,000/µL; Bone Marrow Blasts: \<5%; Other: Either neutrophils or platelets not recovered, no extra medullary disease.
Up to 24 months
Secondary Outcomes (1)
Progression-free survival (PFS)
Up to 24 months
Study Arms (2)
Arm A (sEPHB4-HSA, cytarabine)
EXPERIMENTALParticipants receive recombinant EphB4-HSA fusion protein IV over 60 minutes on days 1, 8, 15, and 22 and cytarabine IV over 4 hours on days 1-5. Treatment repeats every 28 days for up to 2 courses in the absence of disease progression or unacceptable toxicity.
Arm B (sEPHB4-HSA, vincristine liposomal)
EXPERIMENTALParticipants receive recombinant EphB4-HSA fusion protein IV over 60 minutes on days 1, 8, 15, and 22 and vincristine liposomal IV over 60 minutes on days 1, 8, 15, and 22. Treatment repeats every 28 days for up to 2 courses in the absence of disease progression or unacceptable toxicity.

Eligibility Criteria
You may qualify if:
- Confirmed diagnosis of relapsed or refractory acute leukemia (acute myeloid leukemia, acute lymphoblastic leukemia, blast crisis of chronic myeloid leukemia \[CML\], secondary AML from prior myelodysplastic syndrome \[MDS\] / myeloproliferative neoplasm \[MPN\]); minimum of 5% blasts in the bone marrow or 10% blasts in circulation
- Patients with Philadelphia chromosome (Ph)+ ALL or blast crisis of CML must be refractory (not intolerant) to at least 2 second/third generation ABL kinase inhibitors (TKI)
- For AML: patients must belong to one of the following ?high risk? categories:
- Primary induction failure (PIF) as defined by failure to achieve at least a 50% reduction in bone marrow blasts after one cycle of high intensity, anthracycline containing induction regimen or failure to achieve complete response (CR)/complete remission with incomplete blood count recovery (CRi) after two cycles of high intensity chemotherapy
- First early relapse as defined by an initial remission duration of fewer than 6 months
- Second or subsequent relapse regardless of remission duration, or
- Relapse after allogeneic or autologous stem cell transplantation (first relapse after stem cell transplant would be eligible, regardless of prior duration of remission)
- Patients with MDS who transform to AML while on hypomethylator agents or patients with AML who progress on hypomethylator agents could be considered for arm A of this trial if
- They choose not to be treated on or are ineligible for the investigator's competing trial of sEPHB4-HSA + hypomethylator (9L-16-6)
- They are appropriate for high dose cytarabine treatment
- For ALL: patients must belong to one of the following ?high risk? categories:
- Primary refractory as defined by failure to achieve CR after induction and at least one salvage therapy
- Second or subsequent relapse
- Relapse after allogeneic or autologous stem cell transplantation (requirement for second relapse does not apply post-transplant)
- All variants of ALL including T-ALL, B / myeloid, lymphoblastic leukemia lymphoma are eligible
- +14 more criteria
You may not qualify if:
- Diagnosis of acute promyelocytic leukemia (M3 classification)
- ALL patient refractory to their first induction only or their first relapse, will be excluded; they must be refractory to at least one salvage therapy, or relapse after first salvage, to be eligible
- ALL patients refractory to liposomal vincristine as defined by progression while on therapy or relapse within 3 months of completion of therapy with liposomal vincristine
- Prior malignancy requiring therapy within the last 12 months (excluding non-melanoma skin cancer); hormone therapy for prostate cancer or adjuvant endocrine therapy for breast cancer would not be excluded
- Patient is receiving other investigational agents
- Active central nervous system (CNS) disease
- Definition: any patient receiving active CNS therapy (defined as more than 1 intrathecal treatment per week or current radiation therapy to brain); if patient has a history of CNS disease: must have cerebrospinal fluid (CSF) sampling within 28 days of enrollment that is negative for leukemia; intrathecal chemotherapy for patients without active CNS disease is allowed (e.g., ongoing primary or secondary prophylaxis for patients who cleared the CSF prior to study enrollment); CSF sample is not required for enrollment for patients with no history of CNS disease
- Chemotherapy within 2 weeks of first dose of sEPHB4-HSA (minimum of 6 weeks for nitrosoureas and 8 weeks for bone marrow transplantation) with the following exceptions:
- Hydroxyurea allowed prior to, and up to day +5 of cycle 0 of treatment (max 100 mg/kg/day)
- Corticosteroids allowed until day -3 (max dexamethasone 20mg/day)
- Maintenance chemotherapy for ALL allowed one week prior to start of treatment (e.g., POMP)
- Grade ? 2 toxicity (other than alopecia) continuing from prior anticancer therapy, including radiation
- Patients with Charcot-Marie-Tooth disease or other demyelinating diseases are excluded from the liposomal vincristine containing arm
- New York Heart Association class 3 or 4 heart failure; myocardial infarction, acute coronary syndrome, diabetes mellitus with ketoacidosis, or chronic obstructive pulmonary disease (COPD) requiring hospitalization in the preceding 6 months; or any other intercurrent medical condition that contraindicates treatment with sEPHB4-HSA or places the patient at undue risk for treatment related complications
- Uncontrolled active systemic infections
- +2 more criteria
