Volitinib in Treating Participants with Recurrent or Refractory Medulloblastoma, High-Grade Glioma, or Diffuse Intrinsic Pontine Glioma

Why are we doing this research?

This phase I trial studies the best dose and side effect of volitinib in treating participants with Medulloblastoma, High-Grade Glioma or Diffuse Intrinsic Pontine Glioma that have come or does not respond to treatment. Volitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

PBTC-049:  A Phase I study of Savolitinib in Recurrent, Progressive or Refractory Medulloblastoma, High-Grade Glioma, or Diffuse Intrinsic Pontine Glioma

Who can participate?

Inclusion Criteria:

  • Patients with a histologically confirmed diagnosis of a primary CNS tumor (medulloblastoma, high-grade glioma, or diffuse intrinsic pontine glioma [DIPG]) that is recurrent, refractory or progressive. All tumors must have histologic verification at either the time of diagnosis or recurrence except patients with diffuse intrinsic brain stem tumors. These patients must have radiographic or clinical evidence of progression
    • Note: Refractory disease is defined as the presence of persistent abnormality on conventional magnetic resonance imaging (MRI) imaging that is further distinguished by histology (biopsy or sample of lesion) or advanced imaging, OR as determined by the treating physician and discussed with the primary investigator prior to enrollment
  • Efficacy expansion cohort: Patients must have a recurrent, progressive or refractory primary CNS tumor with evidence of genetic activation of the MET pathway, regardless of histology. The submitted specimen can be from diagnosis or recurrence and there is no time limit from when the specimen was obtained to enrollment onto the efficacy expansion cohort. The assessment will be performed in a Clinical Laboratory Improvement Act (CLIA) certified laboratory.
