A Phase II Trial of Poly ICLC in Patients With Recurrent Anaplastic Glioma

Inclusion Criteria

DISEASE CHARACTERISTICS:

- Histologically confirmed intracranial anaplastic glioma, including any of the
following subtypes:

- Anaplastic astrocytoma

- Anaplastic oligodendroglioma

- Anaplastic mixed oligoastrocytoma

- Other anaplastic gliomas NOTE: Patients with an original histology of low-grade
glioma are allowed provided a subsequent histological diagnosis of an anaplastic
glioma is made

- Must have evidence of tumor recurrence or progression by MRI or CT scan* NOTE:
*Steroid dose must be stable for at least 5 days before scan

- Prior radiotherapy required

- Patients who have had prior interstitial brachytherapy or stereotactic
radiosurgery must have confirmation of true progressive disease rather than
radiation necrosis by positron-emission tomography, thallium scanning, magnetic
resonance spectroscopy, or surgical documentation of disease

- Relapsed disease

- Progression after initial therapy (e.g., radiotherapy with or without
chemotherapy)

- No more than 3 prior therapies (initial therapy and treatment for no more than 2
prior relapses)

- Surgical resection for relapsed disease with no anticancer therapy for up to 12
weeks followed by another surgical resection is considered 1 relapse

- For patients who have had prior therapy for a low-grade glioma, the surgical
diagnosis of high-grade glioma is considered the first relapse

- Must be registered in the North American Brain Tumor Consortium Data Management
Center database
