Brief Summary:
This phase I trial studies the side effects and best dose of volitinib in treating patients with primary central nervous system (CNS) tumors that have come back (recurrent) or does not respond to treatment (refractory). Volitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Condition or disease Intervention/treatment Phase
Recurrent Diffuse Intrinsic Pontine Glioma Recurrent Malignant Glioma Recurrent Medulloblastoma Recurrent Primary Central Nervous System Neoplasm Refractory Diffuse Intrinsic Pontine Glioma Refractory Malignant Glioma Refractory Medulloblastoma Refractory Primary Central Nervous System Neoplasm Drug: Savolitinib Phase 1

Detailed Description:


I. To estimate the maximum tolerated dose (MTD) and recommend a phase II dose of volitinib (savolitinib) administered orally daily in children with refractory, progressive or recurrent primary CNS tumors.

II. To define and describe the toxicities of savolitinib in children with refractory, progressive, or recurrent primary CNS tumors.

III. To characterize the pharmacokinetics of savolitinib in children with refractory, progressive, or recurrent primary CNS tumors.


I. To preliminarily define the antitumor activity of savolitinib within the confines of a phase I study.

II. To perform a genomic analysis within the confines of a phase I study to investigate correlation between response to treatment (as measured by objective response or progression free survival [PFS]) and the presence of specific genomic alterations (e.g. MET amplification, chromosome 7q aneuploidy, MET mutation, or HGF amplification) and/or specific subgroups of disease.

OUTLINE: This is a dose-escalation study.

Patients receive volitinib orally (PO) once daily (QD). Treatment repeats every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 30 days, then periodically for up to 2 years.

Primary Outcome Measures :
  1. Maximum tolerated dose of volitinib [ Time Frame: Up to 30 days post treatment ]
    Will be defined as the highest dose level at which six patients have been treated with at most one patient experiencing a dose limiting toxicity and the next higher dose level has been determined to be too toxic.

  2. Recommend phase II dose [ Time Frame: Up to 30 days post treatment ]

Secondary Outcome Measures :
  1. Objective responses (complete response + partial response) [ Time Frame: Up to 2 years ]
    Will be described by dose and by histology. Prolonged stable diseases will also be reported in a descriptive fashion.

  2. Molecular analyses of tumors [ Time Frame: Up to 2 years ]
    Will be reported descriptively.

  3. Pharmacokinetic Parameters [ Time Frame: Up to 2 years ]
    Will be presented in tabular and graphical form. Pharmacokinetic parameters of interest, such as apparent volume of the central compartment (Vc/F), elimination rate constant (Ke), half-life (t1/2), apparent oral clearance (CL/F), and area under the plasma concentration time curve (AUC) will be estimated using compartmental methods. Dose proportionality in pharmacokinetic parameters will be investigated by performing one-way analysis of variance (ANOVA) on dose-normalized parameters.

  4. Population parameters [ Time Frame: Up to 2 years ]
    Will be estimated using nonlinear mixed effects modeling methods (NONMEM). This method estimates the population parameters and both the inter- and intra-subject variability. Once the population parameters and corresponding covariance matrix are estimated, individual estimates can be obtained using post hoc analysis.

If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required. Pregnant women are excluded from this study because there are unknown but potential risks to an unborn baby from savolitinib. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with savolitinib, breastfeeding should be discontinued if the mother is treated with savolitinib
  • Patients with a known serious active infection including, but not limited to, viral hepatitis, human immunodeficiency virus, tuberculosis
  • Patients with any clinically significant unrelated systemic illness or significant cardiac, pulmonary, hepatic or other organ dysfunction), that in the opinion of the investigator would compromise the patient's ability to tolerate protocol therapy, put them at additional risk for toxicity or would interfere with the study procedures or results
  • Patients with uncontrolled hypertension (i.e., a blood pressure [BP] > 95th percentile for age, height, and gender, patients with values above these levels must have their blood pressure controlled with medication prior to starting study drug)

    • The normal blood pressure by height, age, and gender can be assessed by using the NIH Guidelines on the PBTC Member's website (Protocols- Generic Forms and Templates- Normal Blood Pressure by Height and Age).
  • Patients with any of the following cardiac diseases

    • Congestive heart failure (New York Heart Association >= grade 2)
    • Clinically significant cardiac arrhythmia
    • Mean resting corrected QT interval (QTc) > 450 msec on screening obtained from 3 electrocardiograms (EKGs) or

    • Family history of unexplained sudden death under 40 years of age in first-degree relatives or
    • Any concomitant medication known to prolong the QT interval and cause Torsade de Pointes. These drugs must have been discontinued prior to the start of administration of study treatment in accordance with guidance

Strong inducers of CYP3A4 and CYP3A4 substrates which have a narrow therapeutic range or CYP3A4 sensitive substrates should not be used during the trial or used with caution. Because the lists of these agents are constantly changing, it is important to regularly consult a frequently-updated medical reference.
