Summary
This phase II trial is studying how well ABT-751 works in treating children with neuroblastoma that has relapsed or not responded to previous treatment. Drugs used in chemotherapy, such as ABT-751, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing.
Eligibility Criteria
Inclusion Criteria
- Histologically or cytologically confirmed neuroblastoma meeting the following criteria:
- Refractory or relapsed disease
- No curative treatment option and no additional therapy proven to prolong survival with an acceptable quality of life is available
- Evidence of disease progression (enlargement of existing measurable tumors or the appearance of new tumors) during prior treatment OR biopsy-proven viable neuroblastoma if stable disease but refractory to prior treatment
- Previously irradiated soft tissue or bony lesion must meet ≥ 1 of the following criteria:
- Viable neuroblastoma determined by biopsy ≥ 6 weeks after radiation therapy
- Growth in the lesion determined by CT scan or MRI
- Measurable or evaluable disease
- Measurable disease is defined as ≥ 20 mm in ≥ 1 dimension by MRI, CT scan, or x-ray OR ≥ 10 mm in ≥ 1 dimension by spiral CT scan
- Evaluable disease is defined as iodine I 123 metaiodobenzylguanidine (^123I MIBG)-positive lesion at ≥ 1 site
- Must not have measurable disease by CT scan or MRI
- No elevated urinary catecholamines and/or bone marrow evidence of tumor, without measurable or evaluable disease by imaging modalities (CT scan, MRI, or ^123I MIBG)
- Karnofsky performance status (PS) 50-100% (> 16 years of age) OR Lansky PS 50-100% (≤ 16 years of age)
- Life expectancy ≥ 8 weeks
- Hemoglobin ≥ 7.5 g/dL (transfusions allowed)
- Absolute neutrophil count > 250/mm³
- Platelet count > 25, 000/mm³ (without platelet transfusion support for ≥ 7 days)
- Bilirubin ≤ 1.5 times upper limit of normal (ULN)
- ALT 50% pelvis, craniospinal, or total-body radiation)
- More than 4 months since prior allogeneic stem cell transplantation (SCT) (2 months for autologous SCT) and recovered
- Infusion of autologous peripheral blood mononuclear cells without high-dose chemotherapy or preparative regimen is not considered SCT
- More than 30 days since prior investigational drug therapy
- More than 30 days since prior immunotherapy (monoclonal antibody therapy or vaccine therapy)
- More than 1 week since prior growth factor treatment
- No other concurrent anticancer agents, including chemotherapy, immunomodulating agents, or biologic therapy (retinoids)
- No concurrent radiation therapy, including palliative radiation therapy
- No concurrent treatment for graft-vs-host disease
- No concurrent epoetin alfa, sargramostim (GM-CSF), or interleukin-11
