Poly-ICLC in Treating Patients With Recurrent or Progressive Anaplastic Glioma

RATIONALE: Biological therapies such as poly-ICLC use different ways to stimulate the immune system and stop tumor cells from growing.

PURPOSE: This phase II trial is studying how poly-ICLC works in treating patients with recurrent, progressive, or relapsed anaplastic glioma.

OBJECTIVES:

* Determine the objective response rate in patients with recurrent or progressive anaplastic glioma treated with poly ICLC.
* Determine the efficacy of this drug, in terms of 6-month progression-free survival, in these patients.
* Determine the safety profile of this drug in these patients.
* Determine the survival of patients treated with this drug.
* Determine the tumor response rate in patients treated with this drug.
* Determine the biological effects of this drug in these patients.

OUTLINE: This is a multicenter study.

Patients receive poly ICLC intramuscularly 3 times a week for 4 weeks. Courses repeat every 4 weeks in the absence of disease progression or unacceptable toxicity.

Patients are followed every 3 months.

PROJECTED ACCRUAL: A total of 22-46 patients will be accrued for this study.

Eligibility 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
