简要总结
Therapeutic solutions to treat solid tumors that are resistant to conventional treatments are now limited. Laboratory data in animals (on pediatric tumors such as brain tumors, sarcomas and neuroblastomas) have shown that the combination of irinotecan (HIF1alpha inhibitor) and rapamycin (mTOR inhibitor) allowed to block development of blood vessels in the tumor and could, in some cases, stop its progression. This drug combination has already been tested in adult patients with refractory tumors and seems to give encouraging results with stabilization of the tumor. The dose and toxicity of irinotecan and rapamycin are known when these drugs are administered separately and in a context different from that of refractory tumors. RAPIRI is a phase I clinical trial whose principal objectives are to determine the maximum dose at which these two molecules may be administered and to assess the safety of this new combination of drugs.

研究组 & 干预措施
rapamycin+irinotecan at a given dose
干预措施: Combined administration of irinotecan and rapamycin (Drug)
结局指标
主要结局
Determine the maximum tolerated dose (MTD) of irinotecan and rapamycin combination in children with refractory solid tumors.
时间窗: 28 days
The Dose-Limiting Toxicity (DLT) of the drug combination is determined during the first cycle (J1 to J28) of treatment. MTD will be defined as the dose level immediately below the dose level at which 2 patients in a cohort of 3 to 6 patients will have experienced a DLT.
Characterize the pharmacokinetics of rapamycin and irinotecan during the first cycle of treatment.
时间窗: Day1 + day8
Pharmacokinetic parameters for rapamycin will be evaluated at days 1 and 8 of the first cycle of treatment. Pharmacokinetic parameters for irinotecan will be evaluated at day 1 of the first cycle of treatment. Pharmacokinetic profile will be modelized for each patient.
