131-I-TM-601 Study in Adults With Recurrent High-Grade Glioma
131-I-TM-601 Study in Adults With Recurrent High-Grade Glioma
This drug is being developed to treat a type of brain cancer, glioma. This study was
 developed to evaluate the safety, time to disease progression and survival rates after
 treatment.
This phase II trial was designed in two sequences. The first sequence, which is now complete
 to accrual was an open-label, dose escalation, multi-dose study and treated 12 evaluable
 patients with high-grade glioma.

 The second sequence is currently open and accruing eligible subjects with high-grade glioma.
 The trial is an open-label, randomized study and will accrue a total of 54 evaluable
 patients. Eligible subjects will be randomized to receive either 3 or 6 injections of 131-I
 labeled TM-601 (131-I-TM-601), in weekly intervals at the dose determined in the first
 sequence of the trial. Patients will undergo debulking surgery and placement of a ventricular
 access device into the tumor cavity for administration of 131I-TM-601. Patients who
 participated in the first sequence are not eligible to participate in the second sequence of
 the study.

 High-grade gliomas include; glioblastoma multiforme, anaplastic astrocytoma, oligoastrocytoma
 or gliosarcoma.

 Patients will undergo follow-up clinical examinations and magnetic resonance imaging (MRI)
 assessments, at defined intervals, until 12 months after the first study dose.
Inclusion Criteria:

 -  Patient must have a histologically confirmed unilateral, supratentorial malignant
 glioma (grade 3 or 4, anaplastic astrocytoma, gliosarcoma, glioblastoma multiforme or
 malignant oligoastrocytoma)

 -  Patient must have glioma progression or recurrence following radiotherapy that was no
 less than 50 Gy (+/- chemotherapy; +/- surgery)

 -  Patient must be a candidate for resection of the recurrent tumor (surgical
 requirements are detailed in the study protocol)

 -  Imaging must show recurrent, unilateral, supratentorial tumor(s)

 -  There is no diffuse leptomeningeal disease

 -  For patients with previous radiosurgery or enhanced radiotherapy, based on
 neurosurgeon's judgment, the area of enhancement can be removed during the surgery

 -  Patient must have recovered from toxicity of prior therapy

 -  Patient must be > 18 years of age.

 -  Patient has a Karnofsky Performance Status greater than or equal to 60%

 -  Patient must have a life expectancy of at least 3 months

 -  Patient has no uncontrolled seizures or other neurological conditions which would
 interfere with evaluation

 -  Patient is not currently receiving, or is not anticipated to receive, concomitant
 anticancer agent(s) during the course of this study

 -  Patient must have given informed consent

 Exclusion Criteria:

 -  Patient with concurrent malignancy (except curatively treated basal or squamous cell
 carcinoma of the skin or carcinoma in situ of cervix and/or breast) or patients with
 prior malignancies that have not been disease-free for five years

 -  Patient has presence of non-contiguous satellite lesions

 -  Patient with known allergy to iodine, iodine containing drugs or contrast agent

 -  Patient with the potential for pregnancy or impregnating their partner and who do not
 agree to follow an acceptable birth control method to avoid conception

 -  Pregnant or breast feeding females

 -  Patient is not maintained on a stable corticosteroid regimen

 -  New onset of conditions not present prior to surgery (as detailed in Study Protocol)
 which would make patient an inappropriate study candidate, or as determined by
 Investigator
