Brief Summary:
This is an un-blinded Phase 1 study in which 21 patients suffering from solid advanced paediatric malignancies (14 sarcoma and 7 non-sarcoma patients) are treated with AV0113, an anti-tumour immune therapy with autologous Dendritic Cells (DCs) loaded with tumour cell lysates, in order to investigate its safety and feasibility.
For obtaining a clearer picture of AV0113's utility in the treatment of bone and soft tissue sarcoma, a long-term (LT) follow-up investigation of the 14 sarcoma patients, which will be treated using the AV0113 Dendritic Cell Cancer Immune Therapy (DC-CIT) technology is planned, in order to gather first evidence for a potential LT effect of DC-CIT with AV0113.
Furthermore, a comparison of the 14 sarcoma patients treated with AV0113 DC-CIT with a cohort of matched historic control patients that were treated using standard of care will be conducted. It is planned to analyse 42 historic control sarcoma patients that will be matched for disease, recurrences, relapses etc.

Detailed Description:
In this phase I trial 21 paediatric patients with solid tumours of childhood (14 sarcoma and 7 non-sarcoma patients) that have exhausted all conventional treatment options are recruited for the treatment with AV0113.
Peripheral blood mononuclear cells (MNCs) will be obtained from patients by leukocyte apheresis. Monocytes enriched by density gradient centrifugation from MNCs will be used to generate immature DCs by cultivation in recombinant human interleukin-4 (IL-4) and granulocyte-macrophage colony-stimulating-factor (GM-CSF). These immature DCs will be loaded with autologous tumour cell lysates obtained by needle biopsy or surgery prior to tumour vaccination.The antigen loaded immature DCs will then receive a final maturation stimulus transmitted by exposure to lipopolysaccharide (LPS) and interferon-gamma (IFN-gamma). Maturation enables DCs to present antigen with high efficiency to T-lymphocytes. Subsequently, mature loaded DCs will be injected subcutaneously close to tumour free lymph nodes or intra-nodally into tumour free lymph nodes at weekly intervals for at least 6 weeks.
It is anticipated to establish the feasibility and safety of tumour vaccination in the described clinical setting and to find some clinical and/or experimental evidence for the induction of an anti-tumour immune response.
