Filter by:This is a Phase I study of the combination of three drugs: sirolimus, cyclophosphamide, and topotecan. This is the first study to evaluate the safety and clinical activity of the combination of oral sirolimus, oral cyclophosphamide and oral topotecan in pediatric and young adult patients with relapsed and refractory solid tumors. In this phase I study, the mTOR inhibitor sirolimus will be administered in combination with oral cyclophosphamide and oral topotecan to children with relapsed or refractory solid tumors. The primary aim of this study is to recommend a phase II dose schedule and describe the toxicity of this combination. Myelosuppression will be a targeted toxicity.
The FCCSS is a multicentric national large-scale collaborative population-based study of children treated for a solid tumor before 2000 in France and before the age of 19 years. The study is concerned by improving knowledge about the long-term effects caused by cancer and its treatments including adverse health and social outcomes. The main reason of the FCCSS is to estimate the risk of adverse health and social outcomes that may occur after a cancer treatment and to prevent them by providing adapted follow-up care. The cohort will be followed for up to 20 years from 2011.
The investigators propose a new antitumor cell therapy for treating childhood refractory solid tumours. The aim of this study is explore the graft versus tumour effect mediated by allogenic natural killer cells (NKs). NK cell alloreactivity can be predicted by donor killer immunoglobulin-like receptors (KIRs) and human leukocyte antigen (HLA) class I alleles mismatch. Cells without an inhibitory HLA ligand may trigger natural killer cell activation and elimination of those target cells. Reduced risk of relapsed has been described in malignant cancer after haploidentical stem cell transplantation when HLA ligands against the inhibitory KIRs present in the donor were absent in the recipient (KIR-HLA receptor-ligand mismatch). NK alloreactivity could also be obtained by Natural Killer Receptor (NCR), Toll-Like-Receptors (TLRs) and NKG2D receptor stimulation mediated by cytokines or tumour cell lines. This will be an open, non randomized, Phase I/II clinical trial, with a double objective: therapeutic exploratory. The investigators aim at studying safety and efficacy of haploidentical stem cell transplantation for the treatment of these malignancies with no cure known. Patients will receive an haploidentical stem cell transplantation, followed by IL-15 stimulated NK cells infusion one month after transplantation. Efficacy of the procedure will be evaluated with up-to-date radiological techniques, molecular studies and functional assays.
