About

The purpose of this study is to determine the safety and immunological effects of a vaccine for people diagnosed with high risk neuroblastoma, osteogenic sarcoma, and rhabdomyosarcoma. It is hypothesized that this vaccine could reduce the incidence of relapse.

Full description

MAGE -A1, MAGE- A3, and NY-ESO-1 are antigens that can be found with significant frequency on neuroblastoma, rhabdomyosarcoma, and osteogenic sarcoma, three relatively common solid tumors that in some cases can be associated with a high risk for relapse. In this study each subject will be screened for the presence of these antigens, and an individualized vaccine will be developed and administered using the subject's own dendritic cells (DC).

This study consists of two phases: a screening phase and a treatment/vaccine phase. First, eligible individuals will be consented into the screening phase. Tumor specimens will be tested by immunohistochemistry or RT-PCR for the presence of MAGE- A1, MAGE- A3, and NY-ESO-1. Those testing positive for one or more antigen can be consented for the treatment phase of the study. Blood will be drawn for DC culture, and approximately one month later a series of three vaccines will be administered at two week intervals. Subjects will receive a topical medication called imiquimod to the vaccine site prior to and following each injection, to help immune cells travel into the area. Study participation occurs over 18 months and also involves periodic physical examinations and blood draws.

Inclusion and exclusion criteria

Inclusion Criteria for Screening Phase:

Patient 1 to 70 years of age with neuroblastoma, rhabdomyosarcoma, or osteogenic sarcoma, who have one or more of the following high risk features:

• Neuroblastoma:

  • Stage IV disease
  • Stage III disease with n-myc amplification

• Osteogenic sarcoma:

  • Presence of metastases
  • Elevated alkaline phosphatase or LDH at diagnosis
  • Primary tumor affecting the axial skeleton

• Rhabdomyosarcoma:

  • Stage IV disease
  • Alveolar histology
  • Positive tumor margins, with lymph node positivity

Inclusion Criteria for Vaccine Phase:

• Patient meets all screening criteria and tumor is positive for NY-ESO-1, MAGE- A1, or MAGE-A3 by immunohistochemistry or RT-PCR.
• Patients who are between 3 months and 2 years following the completion of therapy, and have achieved at least a very good partial response to primary therapy.
• No chemotherapy is planned for one month following the last vaccination.

• Potential subjects will be tested for HIV 1 and 2 antibodies, HTLV 1/2 antibodies, and for HIV 1, hepatitis C and hepatitis B virus by NAT testing. - -Subjects testing positive for any of these pathogens will be ineligible for vaccine.
• White blood cells ≥ 2.5 K/µL, Hemoglobin ≥ 8 g/dL, Hematocrit > 25%, and Platelets ≥ 70 K/µL

Experimental group

Description:

MAGE-A1, MAGE-A3, and NY-ESO-1 Vaccine: A regimen of three vaccines every two weeks. Each vaccine will contain 3,000,000-5,000,000 peptide pulsed dendritic cells. Imiquimod, a topical cream, will be applied to the vaccination site before and after each vaccination.
