- Pregnancy Prevention: Patients of childbearing or child fathering potential must be willing to use a medically acceptable form of birth control, which includes abstinence, while being treated on this study.

- Informed Consent: The patient or parent/guardian is able to understand the consent and is willing to sign a written informed consent document according to institutional guidelines.

- Steroids: If patient is on corticosteroids, the dose must be stable or decreasing for at least 5 days prior to enrollment.

Exclusion Criteria

  • Systemic Illness: Patients with any clinically significant unrelated systemic illness (serious infections 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.
  • Other Malignancy: Patients with a history of any other malignancy.
  • Concurrent Therapy: Patients who are receiving any other anticancer or investigational drug therapy are not eligible.
  • Inability to Participate: Patients who in the opinion of the investigator are unwilling or unable to return for required follow-up visits or obtain follow-up studies required to assess toxicity to therapy or to adhere to device usage plan, other study procedures, and study restrictions.
  • Tumor Location: Patients with primarily infra-tentorial or spinal cord tumor are not eligible.
  • Tumor Dissemination: Patients for who clinical suspicion is present of metastatic disease in the CSF or Spine must have MRI of Spine and CSF obtained (Lumbar puncture or through ommaya, EVD or Shunt) with negative cytology. Patients with CSF that is positive for tumor cells or metastatic disease found on MRI are ineligible.
  • Skull Defects: Patients with major skull defects (such as missing bone without replacement) are not eligible.
  • Neurological Disorder: Patients with active implanted electronic devices in the brain or spinal cord such as programmable VP shunts, deep brain stimulators, vagus nerve stimulators, are not allowed.
  • Cardiac Disorder: Patients with pacemaker, defibrillator, or documented significant arrhythmia, are not allowed.
  • Intracranial Objects: Patients with foreign body intracranially, such as bullet fragments, are not allowed, with the exception of VP-shunts (non-programmable) and Ommaya catheters.

Treatment (Optune System)
Patients must have a histologically confirmed diagnosis of supratentorial high-grade glioma or supratentorial ependymoma that is recurrent, progressive or refractory. All patients will use the study device Optune System (Tumor Treating Fields, TTFields).
  • Device: Optune System (NovoTTF-200A System, Tumor Treating Fields, TTFields)
    The Optune, a.k.a. Tumor Treating Fields (TTFields), will be worn for a minimum of 18 hours a day, with a recommendation of 22 hours/day for at least 23 days in a 28-day cycle. Cycle 1 includes 7 days training period, followed by 28 days treatment (total 35 days). The patients will receive multiple 28-day cycles of continuous Optune treatment. In the absence of treatment related serious adverse events or disease progression, Optune will continue up to 26 cycles.

Detailed Description

Primary Objectives:

I To establish the feasibility of treatment with the Optune device in pediatric patients with recurrent/refractory/progressive supratentorial malignant glioma and ependymoma.

II To describe the Optune device treatment-related toxicities in children with recurrent/refractory/progressive supratentorial malignant glioma and ependymoma.

Secondary Objectives:

I To estimate the response rate and Event-Free Survival (EFS) as markers of anti-tumor activity of the Optune device within the context of a feasibility trial.

II To assess the association of anti-tumor activity with compliance in Optune device use within the context of a small feasibility study.

III To explore the impact of the Optune device on the children and families undergoing this therapy, and to explore the association between demographic (e.g., SES, gender), disease (e.g., risk status), treatment, and behavioral variables with health-related quality of life (QoL) changes.

IV To explore the association of apparent diffusion coefficient (ADC) values within the tumor and correlate with response to Optune treatment and EFS.

Outline:

The Optune will be worn for a minimum of 18 hours a day, with a recommendation of 22 hours/day for at least 23 days in a 28-day cycle. Cycle 1 includes 7 days training period, followed by 28 days treatment (total 35 days). The patients will receive multiple 28-day cycles of continuous Optune treatment. In the absence of treatment related serious adverse events or disease progression, Optune will continue up to 26 cycles.

The patients will be followed up for 30 days after the last application of the Optune device.
