Brief Summary:

This study will be carried out in children with diagnosis of cancer with tumors known to express N-glycolylated gangliosides. The disease must be resistant to conventional therapy. The acute toxicity and immune response will be evaluated.

The expression of N-glycolylated gangliosides in tumors has previously been investigated in the tumor sample bank at this Hospital. The expression of N-glycolyl GM3 was shown in neuroblastoma, Ewing's sarcoma, Wilm's tumor and retinoblastoma.

Gliomas and the aforementioned tumor types have a very bad prognosis when conventional treatment is ineffective.

New therapeutic strategies have thus been examined, and several immunotherapeutic approaches, including dendritic cell vaccines, peptide vaccines and anti-idiotype vaccines are currently being assessed.

Racotumomab is an anti-idiotype antibody capable of inducing anti-N-glycolyl GM3 antibodies in patients with melanoma, breast cancer and lung cancer.

Dose escalation studies have shown the safety of racotumomab in the 0.5 to 2 mg dose range. The 1 mg dose level was selected for the ensuing clinical studies.

This clinical trial in children involves three dose levels: 0.15 mg, 0.25 mg and 0.4 mg, owing to the difference in body surface between an adult (1.73 sq. m in average) and the candidate population for this study (0.55 to 0.7 sq. m).

Actual Enrollment : 15 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Phase 1 Study on the Use of Racotumomab Anti-idiotype Antibody in Patients With Pediatric Malignancies That Express N-glycolylated Gangliosides and Are Resistant to Conventional Treatment.
Study Start Date : February 2011
Actual Primary Completion Date : March 2014
Actual Study Completion Date : June 2015

Arm Intervention/treatment
Experimental: Racotumomab Drug: racotumomab
Dosage form: intradermal injection. Dosage: 0.15 mg; 0.25 mg; 0.4 mg. Frequency: 3 biweekly injections or 6 biweekly injections. Duration: 4 weeks or 10 weeks.

Primary Outcome Measures :
  1. Selection of the higher safe dose level for ensuing clinical trials [ Time Frame: Up to 1 year ]
    One of the three dose levels assessed in this study will be selected for further clinical testing in children: 0.15 mg, 0,25 mg or 0.4 mg.

Secondary Outcome Measures :
  1. Assess the immune response to racotumomab treatment [ Time Frame: Up to 1 year ]
    Active specific immunotherapy with racotumomab has shown to elicit antigen-specific immune responses in adult patients. The elicitation of anti-immunogen and anti-ganglioside antibodies will be assessed in serum samples prior and after racotumomab treatment.
