Brief Summary:
A phase I trial in patients with relapsed or refractory leukemia of a human monoclonal antibody that kills B cell acute lymphoblastic leukemia. Trial will study safety, pharmacokinetics, and anti tumor activity of the antibody given as a single agent and with vincristine.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 9 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase I Study of mAb 216 With Chemotherapy for the Treatment of Adult Patients With Relapsed or Refractory B-Lineage Acute Lymphoblastic Leukemia
Study Start Date : May 2006
Actual Primary Completion Date : February 2009
Actual Study Completion Date : July 2009

Intervention Details:
  • Drug: MAb 216
    Dosage: 1.25mg/kg intravenous with dose escalation
    Other Name: Monoclonal Antibody 216
  • Drug: Vincristine
    Dosage: 1.5mg/m2 intravenous weekly X 4
    Other Names:
    • Oncovin
    • leurocristine
    • VCR

Primary Outcome Measures :
  1. In this phase I study the endpoint is the determination of the maximum tolerable dose without toxicity.

Secondary Outcome Measures :
  1. A decrease in leukemic blasts. The study will be terminated if unacceptable doseSecondary endpoints are a decrease in leukemic blasts. The study will be terminated if unacceptable dose limiting toxicity is found. This is a phase I trial to study safety.

  3. M3 marrow (>25% blasts) or >25% leukemic blasts in peripheral blood For patients WITH prior allogeneic BMT:

  1. First or subsequent bone marrow relapse post-BMT
  2. M3 marrow or M2 (>5 % and <25% blasts) if cytogenetic or VNTR confirmation

3.1.3 Confirmation of antibody reactivity Patient's leukemic blasts (peripheral blood or marrow) must be documented to bind mAb 216 in vitro (Teng lab) Patient's RBC documented to NOT express fetal "i" antigen and RBC shown to NOT bind mAb 216 in vitro (Teng lab)

3.1.4 Patient Must Not Be Eligible For Therapies of Higher Priority

3.1.5 Performance Level (See Appendix I) Karnofsky >= 50%

3.1.6 Life Expectancy Must be at least 8 weeks.

3.1.7 Prior Therapy Patients must have fully recovered from the acute toxic effects of all prior chemotherapy, immunotherapy, or radiotherapy prior to entering this study.

  1. Myelosuppressive chemotherapy: Must not have received within one week of entry onto this study.
  2. Biologic, including monoclonal antibodies: At least 2 weeks since the completion of therapy with a biologic agent including monoclonal antibodies.
  3. Hydroxyurea can be used up to 72 hours before study entry

3.1.8 Organ Function Requirements Bone Marrow Function: No hematologic criteria for WBC, Hgb or platelets Patients with thrombocytopenia should be responsive to platelet transfusions and must not have uncontrolled bleeding. Adequate Renal Function Defined As:

  • Shortening fraction of >= 27% by echocardiogram, or
  • Ejection fraction of >= 50% by gated radionuclide study.

3.1.9 Regulatory All patients must sign a written informed consent. All institutional (IRB) and FDA requirements for human studies must be met.

Exclusion Criteria:

3.2.1 CNS 3 or refractory CNS leukemia

3.2.2 Isolated extramedullary relapse

3.2.3 Uncontrolled infection

3.2.4 Lack of mAb 216 binding to patient's leukemic blasts in vitro

3.2.5 Binding of mAb 216 to the "i" antigen on patient's erythrocytes
