Testing a vaccine that targets a virus found in glioblastoma tumors
Original title: Immunotherapy Targeting of Cytomegalovirus Antigens in Glioblastoma
How far along is this research?
This is a trial that is enrolling or has been updated. It is not a finding yet.
This is an early test to check if the vaccine is safe in people.
Status: Recruiting. It is looking for patients now. Talk to your care team about whether it fits you.
The trial team last updated this record on . Always check the trial page for the latest.
The short version
This study is testing whether a new vaccine is safe for people with newly found glioblastoma: A glioma that is given grade 4, the highest grade. It grows fast. Treatment usually starts soon after it is found. It often means surgery, then radiation and chemotherapy. See the glossary.
Who this trial is for. This trial is for adults who were just told they have glioblastoma: A glioma that is given grade 4, the highest grade. It grows fast. Treatment usually starts soon after it is found. It often means surgery, then radiation and chemotherapy. See the glossary. Their tumor must have a certain gene pattern called MGMT-unmethylated. It tests a vaccine called PEP-CMV, given along with one round of the chemo drug temozolomide: A chemotherapy taken as a capsule, used for some brain tumors. Your team checks your blood counts while you are on it. See the glossary.
Where it stands. Doctors have found signs of a common virus, called CMV, inside glioblastoma: A glioma that is given grade 4, the highest grade. It grows fast. Treatment usually starts soon after it is found. It often means surgery, then radiation and chemotherapy. See the glossary tumors. The vaccine is meant to help the body's defense system go after it. This early trial is checking whether the vaccine is safe and how well people handle it. The trial has not reported results yet.
What this means, and what it doesn't
What it could mean: This is a first step to see if this kind of vaccine is safe to use. If you have newly found glioblastoma: A glioma that is given grade 4, the highest grade. It grows fast. Treatment usually starts soon after it is found. It often means surgery, then radiation and chemotherapy. See the glossary with this gene pattern, you could ask your care team if this trial fits you. Only the trial team can decide who may join.
What it doesn't mean: This trial is a test, not a proven treatment. We do not know yet if the vaccine is safe or if it helps. Joining a trial does not promise that you will be helped. This is not a cure.
