Pre-registration (Pre-Surgery) Eligibility Criteria

• Histologic documentation: Prior histologic diagnosis of GBM at first occurrence
• Stage: First or second recurrence of GBM or gliosarcoma considered to be surgically resectable
• Prior Treatment:
  • No radiotherapy within 90 days prior to pre-registration
  • No prior treatment with any anti-angiogenic agent targeting the VEGF pathway including but not limited to bevacizumab, cediranib, vandetanib, sunitinib, pazopanib, aflibercept, or sorafenib
  • No prior treatment with HSPPC-96 or other investigational immunotherapy
  • Must have received prior treatment with radiotherapy and temozolomide for histologically confirmed GBM at initial diagnosis
  • No tumor directed therapy for most recent progression
  • No prior Gliadel® wafers
• No clinically significant cardiovascular disease:
  • Patients with a history of hypertension must be well controlled (<150/90) on a regimen of antihypertensive therapy.
  • History of arterial thrombotic events within the past 6 months, including transient ischemic attack (TIA), cerebrovascular accident (CVA), peripheral arterial thrombus, unstable angina or angina requiring surgical or medial intervention in the past 6 months, or myocardial infarction (MI). Patients with clinically significant peripheral artery disease (i.e., claudication on less than one block), significant vascular disease (i.e., aortic aneurysm, history of aortic dissection) are not eligible.
  • Patients who have had a deep vein thrombosis or pulmonary embolus within the past 6 months are eligible if they are on stable therapeutic anticoagulation
  • No current New York Heart Association classification II, III or IV congestive heart failure
• No significant bleeding within the past 6 months; no bleeding diathesis or coagulopathy
• No history of abdominal fistula, gastrointestinal perforation, or intra-abdominal abscess within past 12 months
• No evidence of any systemic autoimmune disease (e.g. Hashimoto's thyroiditis) and/or any history of primary or secondary immunodeficiency, and no immunosuppressant therapy (with the exception of dexamethasone as noted below) for any reason
• Age ≥ 18 years of age

• No more than 16 mg dexamethasone (or equivalent) per day
• Non-pregnant and non-nursing

Registration (Post-Surgery) Eligibility Criteria

• Pre-registration eligibility criteria continue to be met
• Histologic documentation: confirmed histological diagnosis of recurrent GBM or gliosarcoma
• ≥ 90% surgical resection of recurrent GBM confirmed by central radiology review by MRI with or without gadolinium per institutional guidelines. A CT scan is allowable in place of MRI only in situations where an MRI is contraindicated (e.g., patient has a heart pacemaker, metallic devices in the eye, brain or spine, severe claustrophobia).
• ≥ 7 grams of resected tumor available for vaccine manufacture as determined by institutional pathologist
• Availability of ≥ 6 clinical vials of HSPPC-96
• Required Initial Laboratory Values:
  • Granulocytes ≥1,500/µL
  • Platelet count ≥100,000/µL
  • Total Bilirubin ≤ 2.0 x ULN
  • UPC ratio <1 or Urine protein ≤ 1+
  • Calculated creatinine clearance ≥ 45 ml/min
  • SGOT/SGPT(AST/ALT) ≤ 2.5 x ULN
• No serious, non-healing wounds or ulcers
• At least 7 days since any minor surgery such as port placement
• No major surgical procedures, open biopsy or significant traumatic injury ≤ 28 days prior to registration or anticipation of need for elective or planned major surgical procedure during the study. Core biopsy or other minor surgical procedures ≤7 days prior to registration.
• No active or recent hemoptysis (≥½ teaspoon of bright red blood per episode) ≤ 30 days prior to registration
• No new bleeding on D28 (+/-3) MRI (or CT if MRI is contraindicated)
• No clinical deterioration at the time of registration/randomization
• If a second surgery is needed for completion of resection, this should be within 30 days from the first surgery
