Phase III Study of Rindopepimut/GM-CSF in Patients With Newly Diagnosed Glioblastoma

Status: Recruiting
Phase: Phase 3
Diagnosis: Breast: Early Stage Disease
NCT ID: NCT01480479 (View complete trial on
DFCI Protocol ID: 13-308


This 2-arm, randomized, phase III study will investigate the efficacy and safety of the addition of rindopepimut (an experimental cancer vaccine that may act to promote anti-cancer effects in patients who have tumors that express the EGFRvIII protein) to the current standard of care (temozolomide) in patients with recently diagnosed glioblastoma, a type of brain cancer. All patients will be administered temozolomide, the standard treatment for glioblastoma. Half the patients will be randomly assigned to receive rindopepimut and half the patients will be randomly assigned to receive a control called keyhole limpet hemocyanin. Patients will be treated in a blinded fashion (neither the patient or the doctor will know which arm of the study the patient is on). Patients will be treated until disease progression or intolerance to therapy and all patients will be followed for survival.
