Acute Myeloid Leukemia Arising From Previous Myelodysplastic Syndrome, Chronic Myelomonocytic Leukemia, Previously Treated Myelodysplastic Syndrome, Recurrent Acute Myeloid Leukemia With Myelodysplasia-Related Changes, Recurrent Adult Acute Myeloid Leukemia
Conditions
Brief summary
This trial studies the side effects of recombinant EphB4-HSA fusion protein when given together with azacitidine or decitabine in treating patients with myelodysplastic syndrome, chronic myelomonocytic leukemia, or acute myeloid leukemia that has come back or has not responded to previous treatment with a hypomethylating agent. Recombinant EphB4-HSA fusion protein may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Hypomethylating agents, such as azacitidine and decitabine, slow down genes that promote cell growth and can kill cells that are dividing rapidly. Giving recombinant EphB4-HSA fusion protein together with azacitidine or decitabine may work better in treating patients with myelodysplastic syndrome, chronic myelomonocytic leukemia, or acute myeloid leukemia.
Detailed description
PRIMARY OBJECTIVES: I. To describe the toxicities and assess the tolerability of recombinant EphB4-HSA fusion protein (sEphB4-HSA) in combination with an approved hypomethylating agent (HMA) among patients with myelodysplastic syndrome (MDS) who are refractory to or have lost their response to one or more HMAs and among patients with relapsed/refractory acute myeloid leukemia (AML) previously treated with a HMA. SECONDARY OBJECTIVES: I. To measure the expression of EphB4 among marrow and peripheral blood blasts in patients with MDS & AML at baseline and over the course of treatment. II. To measure the expression of immune check-point activating ligands (such as PD-L1, PD-L2) on marrow and peripheral blood blasts in patients treated with HMA and sEphB4-HSA in combination. III. To profile immune subsets (activated and exhausted T cells, natural killer \[NK\] cells, T regulatory cells, and myeloid derived suppressor cells) in the peripheral blood and marrow in patients treated with HMA and sEphB4-HSA in combination. IV. To assess efficacy of sEphB4-HSA in combination with an HMA as manifest by International Working Group (IWG) response criteria, as well as time to development of acute myeloid leukemia (AML) in patients with MDS and time to progression. OUTLINE: Patients receive recombinant EphB4-HSA fusion protein intravenously (IV) over 60 minutes on days 1 and 15. Patients also receive azacitidine IV or subcutaneously (SC) on days 1-7 or days 1-5 and 8-9, or decitabine IV on days 1-5. Administration of recombinant EphB4-HSA fusion protein occurs before or after the HMA (not concurrently). Treatment repeats every 28 days for up to 12 courses in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up every 6 months.

Inclusion criteria
* Adult subjects with advanced MDS requiring treatment with HMA and either refractory to at least 4 cycles or progressing after previously documented response * Patient must be treated within 6 months of the last HMA treatment and must be willing to be treated with the same agent they last received on this study * Prior treatment with novel HMA analog of decitabine on clinical trial is allowed; in such cases, decitabine will be used as the standard of care agent * MDS classified as intermediate 1-risk or high risk according to the international prognostic scoring system (IPSS) or revised-IPSS * Chronic myelomonocytic leukemia (CMML) * Acute myeloblastic leukemia (AML) that was previously treated with HMA and is unfit for intensive chemotherapy * Patient must be within 6 months of prior treatment with HMA and must be willing to be treated with the same agent on this study * During the 8 weeks prior to inclusion in study, subjects must have a baseline bone marrow examination including all of the following: * Cytomorphology to confirm bone marrow blasts * Cytogenetics * Eastern Cooperative Oncology Group (ECOG) status 0-2 * Subject is able to understand and willing to comply with protocol requirements and instructions * Subject has signed and dated informed consent * Total bilirubin (except for Gilbert's syndrome) =\< 2.5 x upper limit of normal (ULN) * Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) =\< 3 x ULN * Creatinine =\< 2.5 x ULN * Women of childbearing potential (WOCBP) and male patients with WOCBP as partners must be using an adequate method of contraception to avoid pregnancy throughout the study and for up to 12 weeks after the last dose of the investigational agent; subject is practicing an acceptable method of contraception (documented in case report form \[CRF\]); WOCBP include any female who has experienced menarche and who has not undergone successful surgical sterilization (hysterectomy, bilateral tubal ligation, or bilateral oophorectomy) or is not postmenopausal; post menopause is defined as: * Amenorrhea \>= 12 consecutive months without another cause or * For women with irregular menstrual periods and on hormone replacement therapy (HRT), a documented serum follicle stimulating hormone (FSH) level \> 35 mIU/mL * Women who are using oral contraceptives, other hormonal contraceptives (vagina products, skin patches, or implanted or injectable products), or mechanical products such as an intrauterine device or barrier methods (diaphragm, condoms, spermicides) to prevent pregnancy, or are practicing abstinence or where their partner is sterile (e.g., vasectomy) should be considered to be of childbearing potential * WOCBP must have a negative serum test (minimum sensitivity 25 IU/L or equivalent units of human chorionic gonadotropin \[HCG\]) within 72 hours prior to the start of investigational product * Patients with uncontrolled hypertension

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Assessment of Toxicity to Hypomethylating Agent (HMA) | Up to 13 months (up to 12 cycles + 30 days) from the start of treatment. | Toxicity will be assessed and graded according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version (v)4.0, after each cycle. |
| Overall Response Defined as the Occurrence of Complete Response, Marrow Complete Response, Partial Response, or Hematological Improvement | Up to 56 days (2 courses of protocol treatment) | Responses assessed by the International Working Group (IWG) 2023 criteria are a set of standardized guidelines used to assess treatment response in patients with myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML). These criteria are designed to evaluate a patient's response based on hematologic improvements, such as changes in blood counts and transfusion independence. |
| Time to Death From Any Cause | up to 1 year (12 cycles) | Will be displayed with Kaplan-Meier plots. |
| Time to Disease Progression | up to 1 year (12 cycles) | This will be measured from the start of treatment to the first disease progression or recurrence. Patients who are progression free at the time of last follow-up will be censored; death prior to progression will be counted as an event. |
| Tolerability Defined as the Ability to Complete Two Courses of Treatment Without the Occurrence of Dose Limiting Toxicity and the Ability to Begin Course 3 Within 4 Weeks and Graded According to the NCI CTCAE v4.0 | Up to 3 months | Will be tabulated and reported according to grade, type, cycle, and attribution. |
