Brief Summary:
Previous research has demonstrated that investigators can coat (arm) T cells with a special molecule called GD2 bispecific antibody that will help T cells recognize neuroblastoma and osteosarcoma cells and kill them. This bispecific antibody recognizes GD2, a protein found on almost all neuroblastoma and osteosarcoma cells. The investigators put the GD2 bispecific antibody on T cells and give large numbers of these T cells back to patients. The investigators think that these T cells may have a better chance of killing GD2 expressing tumor cells when they are armed with GD2 bispecific antibody. This trial studies the side effects and best dose of activated T cells armed with GD2 bispecific antibody and how well they work in treating patients with neuroblastoma, osteosarcoma, and other GD2-positive solid tumors.

Condition or disease Intervention/treatment Phase
Disseminated Neuroblastoma Recurrent Neuroblastoma Biological: IL-2 Biological: GD2Bi-aATC Biological: GM-CSF Other: laboratory evaluations of immune responses Phase 1 Phase 2

Detailed Description:


I. To perform a phase I dose-escalation study in patients with recurrent or refractory neuroblastoma (NB) and other GD2-positive tumors to evaluate the safety and tolerability and to determine the maximum tolerated dose (MTD) for anti-CD3 x hu3F8 bispecific antibody (GD2Bi)-armed activated T cells (aATC) infused twice a week for a total of eight infusions in combination with daily IL-2 (300,000 IU/m^2/day) and GM-CSF (250 ug/m^2 twice per week) in a standard 3 + 3 dose escalation schema with 40, 80, and 160 x 10^6 cells/kg/infusion dose levels.

II. To conduct a phase II clinical trial to explore efficacy and confirm the toxicity profile of GD2Bi-aATC combined with IL-2 and GM-CSF in a phase II expansion cohort of 22 patients with neuroblastoma (NB) using MTD determined in the phase I.


I. Evaluate immune responses in the phase I/II trial by sequential monitoring of anti-NB cytotoxicity of peripheral blood lymphocytes and IFN-gamma EliSpots directed at NB lines.

II. To evaluate persistence of aATC in the blood and tumor biopsies by staining for murine IgG2a to confirm trafficking of armed T cells to tumor.

III. To conduct exploratory study of (18F FDG) positron emission tomography (PET)/computed tomography (CT) after armed ATC infusions in selected patients with PET/CT measurable soft tissue and skeletal lesions.

OUTLINE: This is a phase I, dose-escalation study of OKT3/humanized 3F8 bispecific antibody-aATC followed by a phase II study.

Patients receive IL-2 subcutaneously (SC) daily on days -2 to 35, sargramostim SC twice weekly for 4 weeks, and OKT3/humanized 3F8 bispecific antibody-aATC intravenously (IV) over 30 minutes twice weekly for 4 weeks.

After completion of study treatment, patients are followed up at 1, 3, 6, and 12 months.

  • Patients should not receive any other experimental or phase 1 therapy within 3 weeks prior to study enrollment and monoclonal antibody therapy within 6 weeks
  • To be eligible for phase I study patients should have primary refractory or relapsed disease as evidenced by:

    • Local tumor recurrence measurable on CT or magnetic resonance imaging (MRI) scans with or without metastatic lesions
    • Refractory bone marrow involvement in patients with NB
    • NB with MIBG-positive skeletal lesions
  • The presence of radiographically measurable disease immediately prior to start of Phase I immunotherapy is not an eligibility requirement in the following situations:

    • In patients with NB who have documented bone marrow (BM) involvement;
    • In patients with NB who have MIBG-positive bony lesion(s);
