The purpose

Background: GBM refers to a specific kind of brain cancer called glioblastoma. The standard treatment for GBM is radiation plus temozolomide, an oral chemotherapy drug. Pembrolizumab is an immune therapy that is now used to treat other cancers. The addition of pembrolizumab to the standard treatment of radiation and temozolomide has been shown to be well tolerated. Researchers want to see if adding a vaccine made from the person s own tumor will improve the effect of the pembrolizumab. The vaccine which is developed from fresh tumor taken at the time of surgery is called HSPPC-96. Objectives: To see if the adding pembrolizumab and HSPPC-96 improves the standard treatment for glioblastoma multiforme. Eligibility: Adults at least 18 years old with glioblastoma. Design: Participants will be screened with typical cancer tests: Brain scan Medical history Blood and urine tests Questions about quality of life and symptoms These tests will be repeated throughout the study. Participants will have surgery to remove their tumor. A tissue sample from the tumor will be sent to a lab. A vaccine will be made from it. Some participants will get pembrolizumab and vaccine. Some will get pembrolizumab and placebo. Participants will not know which they get. Participants will get radiation for 6 weeks. Participants will take temozolomide by mouth before each treatment. Participants will get pembrolizumab by IV for 30 minutes 3 times over the radiation cycle. Participants will keep taking the 2 drugs every few weeks for about a year. Some may take pembrolizumab for an additional year. Most participants will get the vaccine or placebo after radiation. They will get it 5 times over 6 weeks. Some participants will continue to get the vaccine every few weeks for 1 or 2 years. Participants will repeat the screening tests when they stop study treatment. They will also have follow-up phone calls.
