Brief Summary:
This randomized phase II trial studies how well giving vaccine therapy with or without bevacizumab works in treating patients with recurrent glioblastoma multiforme that can be removed by surgery. Vaccines consisting of heat shock protein-peptide complexes made from a person's own tumor tissue may help the body build an effective immune response to kill tumor cells that may remain after surgery. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them. It is not yet known whether giving vaccine therapy is more effective with or without bevacizumab in treating glioblastoma multiforme.

Condition or disease Intervention/treatment Phase
Recurrent Glioblastoma Recurrent Adult Brain Tumor Gliosarcoma Biological: HSPPC-96 Drug: bevacizumab Phase 2

Detailed Description:

The purpose of this study is to compare the effects of a vaccine with bevacizumab versus bevacizumab alone on a patient's brain tumor. The vaccine is called heat shock protein peptide complex 96 (HSPPC-96). HSPPC-96 is experimental. Specifically, HSPPC-96 is a protein that may work to help the body have a response against remaining brain tumor cells. Bevacizumab has been approved by the Food and Drug administration for treating brain tumors that grow back. In this study, patients will either get HSPPC-96 vaccine at the same time as bevacizumab, HSPPC vaccine first and then bevacizumab if the tumor comes back, or bevacizumab alone. The use of HSPPC-96 and bevacizumab is investigational.

The primary objective of the study is to determine whether there is an overall survival advantage of HSPPC-96 administered with bevacizumab, given concomitantly or at the point of progression, in comparison with bevacizumab alone in patients with surgically resectable recurrent glioblastoma multiforme.

The secondary objectives are:

  1. to evaluate the safety and tolerability of HSPPC-96 with bevacizumab
  2. to evaluate the progression free survival of HSPPC-96 with bevacizumab, given concomitantly or at the point of progression.

Patients must undergo surgery within 28 days from pre-registration. There must be confirmation of adequacy of tissue for vaccine manufacture, tumor tissue submitted to Agenus, confirmation of ≥ 90% resection by central radiology review and vaccine manufacture of at least six vials. Patients will be randomized to one of three treatment arms. Please see the "Arms" section for more details.

Patients will be monitored approximately 5 years post-surgery.

Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase II Randomized Trial Comparing the Efficacy of Heat Shock Protein-Peptide Complex-96 (HSPPC-96) (NSC #725085, ALLIANCE IND # 15380) Vaccine Given With Bevacizumab Versus Bevacizumab Alone in the Treatment of Surgically Resectable Recurrent Glioblastoma Multiforme (GBM)
Actual Study Start Date : May 2013
Actual Primary Completion Date : April 3, 2017

Arm Intervention/treatment
Experimental: Arm 1, HSPPC-96 + concomitant bevacizumab

HSPPC-96 0.4mL intradermal on days 1 and 8 of cycles 1 and 2, then on day 1 of each cycle, up to a maximum of 12 doses (10 cycles), plus bevacizumab 10 mg/kg intravenous (IV) on day 1 of each cycle, until progression. HSPPC-96 should be administered at least 60 minutes prior to starting bevacizumab infusion. (1 cycle=14 days)

Note: If HSPPC-96 treatment has ended but there is no evidence of disease progression, the patient should continue to receive bevacizumab at the specified dose until progression.

Biological: HSPPC-96
intradermal infusion

Drug: bevacizumab

Experimental: Arm 2, HSPPC-96 with bevacizumab at progression

HSPPC-96 0.4mL intradermal on days 1 and 8 of cycles 1 and 2, then on day 1 of each cycle, up to a maximum of 12 doses (10 cycles). At progression: bevacizumab 10mg/kg intravenous (IV) on day 1 of each cycle, until further progression. (1 cycle = 14 days)

NOTE: It is possible that HSPPC-96 vaccination may end prior to evidence of progression. In this instance it is important to wait until there is confirmed evidence of progression before initiating treatment with bevacizumab.

Upon confirmation of progression the patient should initiate bevacizumab within 7-42 days from the last dose of vaccine.

Biological: HSPPC-96
intradermal infusion

Drug: bevacizumab

Active Comparator: Arm 3, Bevacizumab
Bevacizumab 10mg/kg intravenous (IV) on day 1 of each cycle, until progression. (1 cycle = 14 days)

Primary Outcome Measures :
  1. Overall Survival (OS) [ Time Frame: Up to 5 years post-surgery ]
    The primary endpoint is overall survival (OS), which is defined as the date from study> registration to the date of death, due to any cause.

Secondary Outcome Measures :
  1. Progression Free Survival (PFS) [ Time Frame: Up to 5 years post-surgery ]
    Time to progression free survival: which is defined as the date from study registration to the date of first observation of disease progression or death due to any cause (whichever comes first). Progressive disease is defined as one or more of the following:New contrast-enhancing lesion outside of radiation field on decreasing, stable, or increasing doses of corticosteroids, increase by > 50% enhancement from the first post-surgical scan, or a subsequent scan with smaller tumor size, and the scan 8 weeks or later on stable or increasing doses of corticosteroids, clinical deterioration not attributable to concurrent medication or comorbid conditions is sufficient to declare progression on current treatment, for patients receiving bevacizumab therapy, significant increase in T2/FLAIR non-enhancing lesion.

  2. Toxicity, Assessed Using National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0 (v5) [ Time Frame: Up to 3 years ]
    The maximum grade for each type of toxicity will be recorded for each patient, and frequency tables will be reviewed to determine toxicity patterns within patient groups. In addition, we will review all adverse event data that is graded as 3, 4, or 5 and classified as either "unrelated" or "unlikely to be related" to study treatment in the event of an actual relationship developing. The overall toxicity rates (percentages) for grade 3 or higher adverse events considered at least possibly related to treatment are reported below.
