Overview
Brief Summary
Bortezomib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving bortezomib before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving bortezomib together with temozolomide after surgery may kill any tumor cells that remain after surgery.
This phase II trial is studying how well giving bortezomib before surgery followed by giving bortezomib together with temozolomide after surgery works in treating patients with recurrent malignant glioma.
Detailed Description
Patients receive bortezomib IV on days 1, 4, and 8. Patients then undergo surgical resection of the tumor on day 8 or 9. Beginning approximately 14 days after surgery, patients receive oral temozolomide on days 1-7 and 14-21 and bortezomib IV on days 7 and 21. Treatment repeats every 28 days for up to 2 years in the absence of disease progression or unacceptable toxicity. Tumor tissue and blood samples are collected periodically for biomarker analysis, gene methylation studies, and pharmacokinetic studies. After completion of study therapy, patients are followed up every 3 months for 2 years.

Arms & Interventions
Bortezomib + Temozolomide
Patients receive an injection of bortezomib 1.7mg/m\^2 on days 1, 4 and 8. Patients then undergo their standard of care surgery on day 8 or 9 to remove the tumor. Once recovered from surgery, patients receive combination treatment with temozolomide and bortezomib in periods called cycles (1 cycle = 28 days). Temozolomide is taken by mouth on days 1-7 and 14-21 of each cycle, and bortezomib injections are given on days 7 and 21 of each cycle.
Intervention: Bortezomib

Outcomes
Primary Outcomes
Number of Patients Surviving Without Disease Progression After 6 Months
Time Frame: From date of first treatment until disease progression, death, or early discontinuation of treatment (up to 24 months)
Patients will be monitored from date of first treatment to the date of first observation of progressive disease, non-reversible neurologic progression or increasing steroid requirements, death due to any cause, or early discontinuation of treatment. Progression-free survival will be defined as the absence of any of the above after 6 months. Progression (defined by MacDonald Criteria) is a 25% increase in the sum of products of all measurable lesions over smallest sum observed compared to baseline, OR clear worsening of any evaluable disease, OR appearance of any new lesion/site, OR failure to return for evaluation due to death or deteriorating condition (unless clearly unrelated to the cancer).
Secondary Outcomes
- Number of Participants Achieving a Response to Treatment (Either Complete or Partial Response) as Defined by MacDonald Criteria(Day of treatment post-surgery and then approximately every 8 weeks thereafter until off treatment)
- Number of Grade 1, 2, 3, 4, and 5 Adverse Events Observed During Study Treatment (Defined by CTCAE v 3.0)(Days 1, 4, 8 pre-surgery, and then at the start of every cycle (approximately every 4 weeks) post-surgery while on treatment)
- Overall Survival (in Days)(Days 1, 4, 8 pre-surgery, once per cycle (every 4 weeks) while on treatment post-surgery, and then every 3 months up to 2 years during follow-up)
- Overall Survival Rate at 6 Months(After 6 months on study)
