hsppc-96 vaccine with temozolomide in patients with newly diagnosed gbm

Conditions: Brain and Central Nervous System Tumors

Summary: this phase ii trial studies the side effects and how well hsppc-96 (vitespen) and temozolomide work in treating patients with newly diagnosed glioblastoma multiforme. vaccines made from a person's tumor cells and heat shock protein peptide may help the body to build an effective immune response to kill tumor cells. drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. giving hsppc-96 (vitespen) together with temozolomide may kill more tumor cells.

primary objectives: i. to evaluate the safety profile of hsppc-96 (vitespen) administered concurrently with temozolomide in patients with newly diagnosed glioblastoma multiforme (gbm). ii. to evaluate survival in patients treated with an autologous tumor-derived heat shock protein peptide-complex (hsppc-96) with concurrent temozolomide. secondary objectives: i. to evaluate progression-free survival (pfs) from date of surgical resection. ii. to evaluate the immunologic response to vaccine treatment in a subset of evaluable patients. outline: approximately 2-5 weeks after standard radiation therapy and temozolomide completion, patients receive vitespen intradermally (id) on days 1, 8, 15, and 22. beginning 2 weeks after the 4th dose of vitespen, patients receive a 5th dose of vitespen id and maintenance temozolomide orally (po) on days 1-5 (of 28 day courses). on day 21 of course 1, patients receive the 6th dose of vitespen id and continue vaccinations monthly. courses repeat every 28 days in the absence of vaccine depletion, disease progression, or unacceptable toxicity. after completion of study treatment, patients are followed up every 12 weeks.
