provided that:
- Prior to surgery there was imaging evidence of measurable progressive disease
(PD) as described above.
- Craniotomy or intracranial biopsy site must be adequately healed and free of
drainage or cellulitis, and the underlying cranioplasty must appear intact at the
time of randomization.

test prior to starting therapy

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 4
months after completion of study 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)
- Willingness and ability of the subject to comply with scheduled visits, drug
administration plan, protocol-specified 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
Exclusion Criteria:
- Patients who received temozolomide within 28 days prior to starting first cycle under
this study
- Optune device is not allowed

methimazole and T3 is reached, dexamethasone can be used with a dose determined by
treating physician

infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac
arrhythmia, or psychiatric illness/social situations that would limit compliance with
study requirements
- Computed tomography (CT) scan with contrast within 6 weeks from enrollment as it may
influence thyroid tests due to the iodine content

risk for adverse events in nursing infants secondary to treatment of the mother with
study drugs breastfeeding should be discontinued if the mother will be on treatment
