A Study of Rindopepimut/GM-CSF in Patients With Relapsed EGFRvIII-Positive Glioblastoma

Trial ID or NCT#

NCT01498328

Status

not recruiting iconNOT RECRUITING

Purpose

The purpose of this research study is to find out whether adding an experimental vaccine called rindopepimut (also known as CDX-110) to the commonly used drug bevacizumab can improve progression free survival (slowing the growth of tumors) of patients with relapsed EGFRvIII positive glioblastoma.

Official Title

Patients in Group 2 and 2C must have had disease progression while receiving bevacizumab or within 2 months of treatment with bevacizumab.
Exclusion Criteria:
  1. Among other criteria, patients who meet the following conditions are NOT eligible for the study:
    1. 1. Subjects unable to undergo an MRI with contrast.2. History, presence, or suspicion of metastatic disease3. Prior receipt of vaccination against EGFRvIII.4. Any known contraindications to receipt of study drugs, including known allergy or hypersensitivity to keyhole limpet hemocyanin (KLH), GM-CSF (sargramostim; LEUKINE®), polysorbate 80 or yeast derived products, or a history of anaphylactic reactions to shellfish proteins.5. Use of non-protein based investigational therapy within 14 days prior to Day 1 or use of antibody-based investigational therapy within 28 days prior to Day 1.6. Clinically significant increased intracranial pressure (e.g., impending herniation), uncontrolled seizures, or requirement for immediate palliative treatment7. Evidence of recent hemorrhage on screening MRI of the brain8. Evidence of current drug or alcohol abuse.9. Patients in Group 1 must not have received prior treatment with bevacizumab.
