Brief Summary:
This phase I trial studies the side effects and best dose of anti-PR1/HLA-A2 monoclonal antibody Hu8F4 (Hu8F4) in treating patients with malignancies related to the blood (hematologic). Monoclonal antibodies, such as Hu8F4, may interfere with the ability of cancer cells to grow and spread.

Condition or disease Intervention/treatment Phase
Acute Myeloid Leukemia Arising From Previous Myelodysplastic Syndrome Blast Phase Chronic Myelogenous Leukemia, BCR-ABL1 Positive Hematopoietic and Lymphoid Cell Neoplasm High Risk Myelodysplastic Syndrome Myelodysplastic Syndrome With Excess Blasts-1 Myelodysplastic Syndrome With Excess Blasts-2 Myelofibrosis Recurrent Acute Myeloid Leukemia Recurrent Chronic Myelomonocytic Leukemia Refractory Chronic Myelomonocytic Leukemia Secondary Acute Myeloid Leukemia Drug: Anti-PR1/HLA-A2 Monoclonal Antibody Hu8F4 Other: Laboratory Biomarker Analysis Other: Pharmacological Study Phase 1

Detailed Description:


I. To determine the dose limiting toxicity (DLT) and minimum safe and biologically-effective dose of Hu8F4 when administered intravenously in patients with leukemia or myelodysplastic syndrome (MDS).

II. To determine the pharmacokinetics (PK) of Hu8F4 following study drug administration.


I. To observe the anti-leukemia effects of Hu8F4 in patients with leukemias and MDS.

II. To measure the overall survival, disease-free survival and event-free survival of patients with leukemias or MDS treated with Hu8F4.

OUTLINE: This is a dose-escalation study.

Patients receive anti-PR1/HLA-A2 monoclonal antibody Hu8F4 intravenously (IV) over 60 minutes on days 1 and 15. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Inclusion Criteria:

  • Patients with any of the following diagnoses are eligible: 1) high-risk MDS (i.e. refractory anemia with excess blasts [RAEB-1 or RAEB-2] by World Health Organization [WHO] classification, or any WHO subset with International Prognostic Scoring System [IPSS] intermediate-2 or high, or any patients that have failed prior therapy with hypomethylating agents); 2) chronic myelomonocytic leukemia (CMML); 3) acute myeloid leukemia (AML) by WHO classification; 4) chronic myeloid leukemia in blast phase (CML-BP); 5) myelofibrosis with high-risk features (e.g., accelerated phase disease -10-19% blasts in peripheral blood or bone marrow-, or with Dynamic International Prognostic Scoring System [DIPSS]-plus high risk score)
  • Patients must have relapsed/refractory disease and have failed, or are not candidates for, or have declined all available therapies of proven efficacy; they should also not be eligible for at the time of enrollment or have declined hematopoietic stem cell transplantation
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0-2
  • The effects of Hu8F4 on a fetus or nursing child are unknown; women of child-bearing potential (i.e., women who are pre-menopausal or not surgically sterile) must use acceptable contraceptive methods (abstinence, intrauterine device [IUD], oral contraceptive or double barrier device), and must have a negative urine pregnancy test within 2 weeks prior to beginning treatment on this trial; nursing patients are excluded; sexually active men must also use acceptable contraceptive methods for the duration of time on study

  • Patients must be at least 2 weeks from prior chemotherapy, radiation therapy, or major surgery, and at least 4 weeks or 5 half lives from other investigational anticancer therapy, and have recovered from prior toxicities at least to grade 1; the exception is hydroxyurea that requires no washout prior to the start of study drug
