Racotumomab in Patients With High-risk Neuroblastoma
Open-label, Multicenter, Phase II Immunotherapy Study With Racotumomab in Patients With High-risk Neuroblastoma
This clinical trial will be carried out in children diagnosed with high-risk neuroblastoma that have achieved a complete or very good partial response after standard therapy. An additional cohort of children who could not achieve these response criteria or that relapsed after standard therapy but do not have progressive disease will receive Racotumomab together with metronomic chemotherapy.
The main objectives of this study are to determine the immune response after one-year duration immunization with Racotumomab, to describe the response of Racotumomab therapy in minimal residual disease (MRD) in bone marrow and to describe the toxicity profile of Racotumomab.
Study Overview
Detailed Description
Neuroblastoma is the most common extra-cranial tumor in childhood but prognosis is still poor, even with the advances in its treatment.
New therapeutic strategies have been examined, and several immunotherapeutic approaches, including combined therapy with monoclonal antibodies (anti-GD2), intravenous interleukin-2 (Il-2) and intravenous granulocyte-macrophage colony-stimulating factor (GM-CSF), 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 neuroblastoma.
The expression of the ganglioside N-glycolyl GM3 was shown in neuroblastoma and this expression could be useful as a specific target for immunotherapy.
Ractoumomab will be administered once standard therapy for neuroblastoma has been completed.

Description
Inclusion Criteria:
- Informed Consent or written child assent, if applicable, prior to any specific procedure of the study.
- Aged ≥ 1 year old and ≤ 12 years old at the time of diagnose.
- High-risk neuroblastoma diagnose according to the International Neuroblastoma Risk Group Staging System (INRGSS) (Annex I).

- Use of concomitant metronomic chemotherapy by patients of Group II is considered acceptable.
- For patients belonging to other risk group who have relapsed or progressed, the period between the beginning of chemotherapy for the treatment of high-risk neuroblastoma and the inclusion of patients must not exceed 12 months.
- Partial or complete remission status, very good partial remission or stable disease (pursuant to the International Neuroblastoma Response Criteria) at the time of inclusion (Annex IV).
- Assessment of the disease must be conducted within 30 days prior to inclusion.
- Additional studies supporting the response to treatment at the time of inclusion are required.
