What is the Purpose of this Study?
-Have a procedure where your blood is taken out of a vein in one arm, goes through a machine that takes out white blood cells, and returns the blood back into a vein in the other arm.
-We will take those white blood cells and create Dendritic Cells (DCs) which will be used to make vaccines
-Be randomly assigned (like drawing numbers from a hat) to 1 of 3 groups:
--Group 1 will get unpulsed dendritic cell pre-conditioning prior to DC vaccine #4,
--Group 2 will get tetanus booster prior to DC vaccine #4,
--Group 3 will get tetanus booster prior to DC vaccine #4 and varlilumab (an anti-tumor drug). Varlilumab will be infused (into the vein) 7 days prior to receiving DC vaccines
Both groups will:
-Be asked to come to Duke every 2 weeks for the first 3 vaccines and once a month after the 3rd vaccine (for up to 21 months).
-Have physical exams and blood samples taken
-Have MRI scans as needed
Who Can Participate in this Study?
-Have been newly diagnosed with glioblastoma and had surgery to remove most of the tumor tissue
-Do not have severe reactions to imaging contrast dyes
-Do not have a different cancer requiring active treatment
-Are not taking any types of medicines that affect your immune system.
-Have not had any other medications for your tumor other than steroids prior to starting the study outside of chemo-radiation

What is Involved?
We are doing this study to understand whether the study vaccine, called pp65 CMV dendritic cells, can trigger your immune (protection) system to fight off the tumor cells in your brain.
