Brief Summary

It is an open multicentric phase I/II trial with axitinib (Inlyta®) and metronomic delivery of etoposide for children, adolescent and young adults (AYA) with refractory/ relapsing solid tumors. It is a two-stage trial: First stage: To determine the Maximum Tolerated Dose (MTD) of the combination of axitinib and oral metronomic etoposide for patient with medulloblastoma or ependymoma Second stage: Extension cohort evaluating the preliminary efficacy at the recommended dose for the phase II (RDP2) of the combination. The 2nd stage will start after a meeting of independent data monitoring committee (IDMC). Two cohorts of 9 patients with ependymoma and medulloblastoma Patients treated at first stage won't be included in the second stage.

Conditions

Medulloblastoma; Ependymoma

Outcome Measures

Primary Outcomes (2)

• Dose-limiting toxicity (DLT)

  During first stage

  During the first 28 days (cycle 1)

• Progression-free survival (PFS)

  During second stage, progression-free survival (PFS) computed as the time interval from the beginning of treatment to the date of centrally-assessed with RAPNO criteria. A central review of all imaging is planned at the end of phase 1 and at the end of phase expansion to evaluate tumor response and progressions. PFS-duration of patients alive free of progression at last follow-up will be censored at the date of last visit.

  3 years (from start of treatment to last follow-up visit)

EXPERIMENTAL

1. st stage: Dose escalation The first patient will be included at the level of 1.6 mg/m²/day of axitinib. Patients will be included by cohort of a maximum of 6 patients evaluable for DLT. In the absence of more than 2 patients with DLT during the first 28-day cycle, escalation to the next level will be allowed. Intra-patient dose escalation is not permitted. Non evaluable patients for DLT will be replaced. Six evaluable patients will be enrolled at the last dose level. RP2D will be the DMT or in the absence of DLT the maximum dose evaluated. Treatment will be continued until progression, or unacceptable toxicity for a period of 1 year. Depending on the number of DLTs observed, a maximum of 18 patients should be included. 2. nd stage: extension cohort For the second phase of the study, at RP2D, 2 cohorts of 9 patients (ependymoma, medulloblastoma) will be considered in the study. Treatment will be continued until progression, or unacceptable toxicity for a period of 1 year.

Eligibility Criteria

• Age: 4 Years - 25 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Child (0-17), Adult (18-64)

You may qualify if:

• Histologically proven diagnosis of ependymoma or medulloblastoma
• Methyloma classification performed or available material for methyloma analysis
