Feasibility Trial of Optune for Children With Recurrent or Progressive Supratentorial High-Grade Glioma and Ependymoma
This feasibility trial studies how well the Optune device works in treating younger patients with recurrent/refractory/progressive supratentorial malignant glioma and ependymoma. The TTFields generated by Optune device may inhibit the growth of tumor.
Stanford is currently accepting patients for this trial.

toxicities (defined as ≤ grade 1) of all prior chemotherapy, immunotherapy, or
radiotherapy prior to entering this study.
- Myelosuppressive Chemotherapy: Patients must have received last dose of known
myelosuppressive chemotherapy >21 days prior to enrollment; >42 days if nitrosurea.

related to the agent and received their last dose of the biologic agent > 7 days prior
to study enrollment.
- For agents that have known adverse events occurring beyond 7 days after
administration, this period must be extended beyond the time during which adverse
events are known to occur.

- Monoclonal antibody treatment and agents with known prolonged half-lives: At least
three half-lives must have elapsed prior to enrollment.
- Radiation: Patients must have had their last fraction of:
- Craniospinal irradiation (>24Gy) > 3 months prior to enrollment

such as but not limited to central venous catheter insertion at the discretion of
treating physician and study chair.

groups are eligible for this study.
- Neurologic Status: Patients with neurological deficits should be stable for a minimum
of 1 week prior to enrollment.
- Performance Status: Karnofsky Performance Scale (KPS for > 16 years of age) or Lansky
Performance Score (LPS for ≤ 16 years of age) assessed within two weeks of enrollment
must be ≥ 60. Patients who are unable to walk because of neurologic deficits, but who
are up in a wheelchair, will be considered ambulatory for the purpose of assessing the
- Organ Function: Patients must have organ and marrow function as defined below:
Absolute neutrophil count ≥ 1.0 X 109/L; Platelets ≥ 100 X 109/L (transfusion independent);
Hemoglobin ≥8g/dl (may receive transfusions); Total bilirubin ≤1.5 times institutional
upper limit of normal (ULN); ALT(SGPT) ≤3 times institutional upper limit of normal;
AST(SGOT) ≤3 times institutional upper limit of normal; Albumin ≥2 g/dl. Serum creatinine
based on age/gender as noted below. Patients that do not meet the criteria below but have a
24 hour Creatinine Clearance or GFR (radioisotope or iothalamate) ≥ 70 ml/min/1.73 m2 are

years 1.2 (Male) 1.2 (Female); 13 to < 16 years 1.5 (Male) 1.4 (Female);
≥ 16 years 1.7 (Male) 1.4 (Female).
- Head circumference: Patients must have minimum head circumference of 44 cm.

≥18 hours/day for at least 23 days in a 28-day cycle, and keep head shaved throughout
- Pregnancy Status: Female patients of childbearing potential must have a negative serum
or urine pregnancy test.
- 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
- Steroids: If patient is on corticosteroids, the dose must be stable or decreasing for
at least 5 days prior to enrollment.
- 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
- 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.
