Low-Grade Glioma
Conditions
Brief summary
The purpose of this study is to determine whether oral vinorelbine is effective in the treatment of children with progressive or recurrent unresectable low grade glioma.
Detailed description
The aim of this study is to determine efficacy of oral vinorelbine in children with progressive or recurrent unresectable low grade glioma, in addition to safety, pharmacokinetic, pharmacogenetic, medical costs and quality of life.
Interventions
Orally vinorelbine 60 mg/m2 D1, 8 and 15 Cycle of 28 days For a maximum of 12 cycles The dose of vinorelbine should be increased to 80 mg/m2 from the 2nd cycle If on D8 and D15, the administration conditions are not met, the administration is canceled and not delayed.

PRIOR OR CONCURRENT THERAPY * Prior treatments containing vinca alkaloids like vincristine and/or vinblastine are authorized * Patients must have fully recovered from the toxic effects of any prior therapy before entering the study. No organ toxicity superior to grade 2 according to NCI-CTCAE v4.0 * An interval of at least 2 months from prior radiotherapy, 6 weeks from nitrosourea chemotherapy, and 4 weeks from other chemotherapy regimen, is required
Exclusion criteria
* Inclusion criteria failure * Prior treatment with intravenous or oral vinorelbine * Known hypersensibility to other vinca-alkaloïdes * Digestive pathology affecting absorption in a important way * Prior surgical resection of stomach or the small intestine * Severe hepatic failure independent from tumoral disease * Fructose intolerance * Leptomeningeal relapse without any available measurable disease on MRI (for example, leptomeningeal relapse with totally resected primary lesion) * Uncontrolled active infection within 2 weeks * Pregnancy or breast feeding woman * Uncontrolled intercurrent illness or active infection * Unsuitable for medical follow-up (geographic, social or mental reasons) * Patients requiring long-term oxygen therapy * Patients with ANC less than 1500/mm3 * Patients vaccinated against yellow fever
