| Eligibility |
Inclusion Criteria:
- Age >= 18 years
- Karnofsky performance status >= 70%
- Life expectancy > 12 weeks as determined by the investigator
- Diagnosis of glioma with at least partial involvement or invasion of thalamus,
cerebral peduncles, midbrain, pons, or medulla. Confirmation of diagnosis by biopsy or
maximal safe resection preferred. If multi-disciplinary tumor board recommend no
benefit and likely harm of attempting biopsy then can establish consensus clinical
diagnosis. If foregoing biopsy then tumor board will estimate tumor stage based on
clinical presentation and radiographic findings.
- Completion of all previous therapy (including surgery and radiotherapy) for the
treatment of cancer >= 4 weeks before the start of study therapy.
- Willingness and ability of the subject to comply with scheduled visits, drug
administration plan, protocolspecified laboratory tests, other study procedures, and
study restrictions.
- Evidence of a personally signed informed consent indicating that the subject is aware
of the neoplastic nature of the disease and has been informed of the procedures to be
followed, the experimental nature of the therapy, alternatives, potential risks and
discomforts, potential benefits, and other pertinent aspects of study participation.
- Patients must have adequate organ and marrow function, within 28 days of Cycle 1 Day 1
of Temozolomide, as defined below:
Hematology:
- Hemoglobin >= 9.0 g/dl (no transfusions allowed within 7 days of cycle 1 day 1 to meet
entry criteria) (within 28 days of cycle 1 day 1 of temozolomide)
- White blood cell (WBC) >= 2000/uL (after at least 7 days without growth factor support
or transfusion) (within 28 days of cycle 1 day 1 of temozolomide)
- Absolute neutrophil count (ANC) >= 1,500/mcL (after at least 7 days without growth
factor support or transfusion) (within 28 days of cycle 1 day 1 of temozolomide)
- Platelets >= 100,000/mcL (no transfusions allowed within 7 days of cycle 1 day 1 to
meet entry criteria) (within 28 days of cycle 1 day 1 of temozolomide)
- Prothrombin time (PT)/partial thromboplastin time (PTT) =< 1.5 x upper limit of normal
(ULN) (within 28 days of cycle 1 day 1 of temozolomide)
Chemistry
- Total bilirubin =< 2 institutional upper limit of normal (ULN) (within 28 days of
cycle 1 day 1 of temozolomide)
- Aspartate aminotransferase (AST)/alanine aminotransferase (ALT) =< 3 institutional
upper limit of normal (ULN) (within 28 days of cycle 1 day 1 of temozolomide)
- Serum creatinine =< 2 mg/dL (or glomerular filtration rate >= 40 mL/min) (within 28
days of cycle 1 day 1 of temozolomide)
- The effects of combination therapy with tumor treating fields (TTF) and temozolomide
on the developing human fetus are unknown. For this reason and because other therapies
used in this trial are known to be teratogenic, female of child-bearing potential
(FCBP) must have a negative serum or urine pregnancy test prior to starting therapy.
- FCBP and men must agree to use adequate contraception (hormonal or barrier method of
birth control; abstinence) prior to study entry and for the duration of study
participation. Should a woman become pregnant or suspect she is pregnant while she or
her partner is participating in this study, she should inform her treating physician
immediately. Men treated or enrolled on this protocol must also agree to use adequate
contraception prior to the study, for the duration of study participation, and 12
months after completion of TTF and Temozolomide administration. A female of
childbearing potential (FCBP) is a sexually mature woman who: 1) has not undergone a
hysterectomy or bilateral oophorectomy; or 2) has not been naturally postmenopausal
for at least 24 consecutive months (i.e., has had menses at any time in the preceding
24 consecutive months.
Exclusion Criteria:
An individual who meets any of the following criteria will be excluded from participation
in this study:
- Patients who have completed chemotherapy or radiotherapy more than 26 weeks prior to
entering the study.
i. Completion of radiotherapy 8-12 weeks prior to starting the tumor treating fields will
be considered a minor deviation.
ii. Completion of radiotherapy 13-26 weeks prior to starting the tumor treating fields will
be considered a major deviation.
- Patients who are receiving any other investigational agents or an investigational
device within 21 days before first administration of study device.
- History of allergic reactions attributed to compounds of similar composition to those
used for transducer placement.
- Uncontrolled intercurrent illness including, but not limited to, ongoing or active
infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac
arrhythmia, or psychiatric illness/social situations that would limit compliance with
study requirements.
- Significant cardiovascular disease (eg, myocardial infarction, arterial
thromboembolism, cerebrovascular thromboembolism) within 3 months prior to start of
study therapy; angina requiring therapy; symptomatic peripheral vascular disease; New
York Heart Association Class 3 or 4 congestive heart failure; or uncontrolled Grade =3
hypertension (diastolic blood pressure =100 mmHg or systolic blood pressure =160 mmHg)
despite antihypertensive therapy.
- Human immunodeficiency virus (HIV)-positive patients on combination antiretroviral
therapy are ineligible because of increased risk of lethal infections when treated
with marrow-suppressive therapy such as Temozolomide. Appropriate studies will be
undertaken in patients receiving combination antiretroviral therapy when indicated.
