GP96 Heat Shock Protein-Peptide Complex Vaccine in Treating Patients With Recurrent or Progressive Glioma

Brain and Central Nervous System Tumors Clinical Trial

Official title: Phase I/II Trial of Heat Shock Protein Peptide Complex-96 (HSPPC-96) Vaccine for Patients With Recurrent High Grade Glioma

Status Completed

Clinical Trial Summary

Vaccines made from a person's tumor cells, such as gp96 heat shock protein-peptide complex, may help the body build an effective immune response to kill tumor cells. This phase I/II trial is studying the side effects and best dose of gp96 heat shock protein-peptide complex vaccine to see how well it works in treating patients with recurrent or progressive high-grade glioma over time.

Clinical Trial Description

PRIMARY OBJECTIVES:

• Phase 1: [closed to accrual as of 7/25/2007]: Determine the safety and best tolerated dose and frequency of gp96 heat shock protein-peptide complex vaccine in patients with recurrent or progressive high-grade glioma.

• Phase 2: Determine the clinical response to treatment, time to disease recurrence and progression, and overall survival of patients treated with this vaccine.

SECONDARY OBJECTIVES:

• Determine the immune response in patients treated with this vaccine.

• Determine survival outcomes in patients treated with this vaccine.

OUTLINE: This is a dose-escalation, phase I study (closed to accrual as of 7/25/2007) followed by a phase II study.

PHASE I [closed to accrual as of 7/25/2007]:

Patients underwent surgical resection. Viable tumor tissue is used to generate the gp96 heat shock protein-peptide complex (HSPPC-96) vaccine. Patients with primary disease receive standard adjuvant therapy after surgery. Patients whose disease progresses during or after standard adjuvant therapy receive the HSPPC-96 vaccine. Patients with recurrent disease receive the HSPPC-96 vaccine between 2-8 weeks after surgery. The HSPPC-96 vaccine is administered intradermally every 1-3 weeks for at least 4 doses and then every 2-3 weeks thereafter in the absence of disease progression, unacceptable toxicity, or vaccine depletion. Cohorts of 6 patients received the HSPPC-96 vaccine at escalating dose frequencies until the maximum tolerated dose (MTD) was determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experienced a dose-limiting toxicity.

PHASE II: Patients received the HSPPC-96 vaccine as in phase I at the appropriate dose frequency determined in phase I (closed to accrual as of 7/25/2007). The HSPPC-96 vaccine is administered intradermally every 1-3 weeks for at least 4 doses and then every 2 weeks thereafter in the absence of disease progression, unacceptable toxicity, or vaccine depletion. After completion of study treatment, patients are followed periodically until death, lost to follow-up, or end of study.

PROJECTED ACCRUAL: A total of 50 patients will be accrued for this study. ;
