Who might be able to join this trial:

For adults with GBM (Group 1):

  • People aged 21 years or older
  • People with a newly diagnosed brain tumour called glioblastoma (GBM, Grade IV), confirmed by laboratory testing, that has a specific molecular feature called MGMT low or unmethylated — this is not a tumour that came from a cancer elsewhere in the body or a returning tumour
  • The tumour must be located in the upper part of the brain (above the brainstem)
  • Tumour tissue must have been collected during surgery in a way that allows it to be processed for the study's special treatment
  • After surgery, the remaining tumour must measure no more than 3 cm on a brain scan (MRI)
  • People who have recovered from surgery and any related complications
  • Brain scans (MRI with contrast dye) must have been done both before and after surgery, within specific timeframes (before surgery: within 28 days of joining the study; after surgery: within 7 days of the operation)
  • People with a general health and function score of 60 or above on a standard medical scale (people in wheelchairs due to paralysis may still meet this requirement)
  • Blood counts and organ function within acceptable ranges: enough white blood cells, platelets, and red blood cells; kidneys and liver working adequately (confirm specific values with trial site)
  • Willingness to take an anti-seizure medication (such as levetiracetam) throughout the vaccination part of the study
  • Ability to give written consent, or having a legal representative do so if needed
  • Women who could become pregnant must have a negative pregnancy test at the time of joining
  • Women who could become pregnant must agree to use an approved method of contraception throughout the study and for at least 24 weeks after the last dose of study treatment
  • Men with female partners who could become pregnant must agree to use approved contraception throughout the study and for at least 24 weeks after the last dose
  • Any neurological problems remaining after surgery must have been stable for at least one week before joining

For children and young people with high-grade brain tumours (Group 2):

  • People aged over 3 and up to 25 years old
  • People with a newly diagnosed high-grade brain tumour (Grade III or IV), confirmed by laboratory testing
  • Tumour tissue must have been collected during surgery in a way that allows it to be processed for the study's special treatment
  • After surgery, the remaining tumour must measure no more than 3 cm on a brain scan (MRI)
  • People who have recovered from surgery and any related complications
  • Brain scans (MRI with contrast dye) must have been done both before and after surgery, within specific timeframes (before surgery: within 28 days of joining; after surgery: within 7 days of the operation)
  • People with a general health and function score of 60 or above on the appropriate scale for their age (wheelchair users due to paralysis may still meet this requirement)
  • Blood counts and organ function within acceptable ranges, including adequate white blood cells, platelets, red blood cells, kidney function, and liver function (confirm specific values with trial site)
  • People receiving steroid medications must be on a stable or reducing dose for more than one week before joining, and the dose must be within a specified limit (confirm with trial site)
  • Willingness to take an anti-seizure medication (such as levetiracetam) throughout the vaccination part of the study
  • A parent, legal guardian, or the participant themselves (where appropriate) must be able to understand and sign the consent documents
  • Female participants who could become pregnant must have a negative pregnancy test at the time of joining
  • Female participants who could become pregnant must agree to use an approved method of contraception throughout the study and for at least 24 weeks after the last dose
  • Male participants who could father a child must agree to use approved contraception throughout the study and for at least 24 weeks after the last dose
  • Any neurological problems remaining after surgery must have been stable for at least one week before joining
  • Participants may need to be enrolled in a separate related study (PNOC COMP) before joining this one, if that study is available at the treating centre (confirm with trial site)

Who may not be able to join:

For adults with GBM (Group 1):

  • People who have had another type of cancer in the past, unless they have been cancer-free for 3 or more years (some early-stage or non-invasive cancers may still be eligible — confirm with trial site)
  • People whose tumour has a methylated MGMT marker
  • People with a specific type of widespread brain tumour called Gliomatosis Cerebri
  • People whose tumour has spread to the lower parts of the brain, outside the skull, or to the lining of the brain and spinal cord
  • People with a returning or multi-site brain tumour
  • People with remaining tumour larger than 3 cm after surgery
  • People who are HIV positive or have Hepatitis B or Hepatitis C
  • People with a known active infection or a condition that weakens the immune system
  • People who need corticosteroid (steroid) medication at doses above a low maintenance level, or who have not reduced to low-dose steroids within one week before scheduled vaccinations
  • People who have previously had chemotherapy or radiation-sensitising treatments to the head or neck area (other than standard TMZ chemotherapy given during radiation for GBM)
  • People who have previously had radiation treatment to the head or neck that would overlap with new radiation fields, or who have had radiosurgery
  • People with serious ongoing health conditions, including unstable heart problems, serious heart rhythm problems or heart attack in the last 6 months, active bacterial or fungal infection requiring intravenous antibiotics, serious breathing problems, liver failure with jaundice or clotting problems, AIDS, autoimmune disease managed with immune-suppressing medications, major psychiatric conditions, active connective tissue disorders such as lupus or scleroderma (confirm with trial site)
  • Women who are pregnant or breastfeeding
  • People with a history of a nerve condition called brachial neuritis or Guillain-Barré syndrome
  • People currently taking part in another clinical trial or who have received experimental treatment within 30 days before joining
  • People who are unwilling or unable to complete the treatment and follow-up visits

For children and young people with high-grade brain tumours (Group 2):

  • People with specific tumour types: diffuse intrinsic pontine glioma, brainstem diffuse midline glioma, or tumours with a particular genetic change called BRAFV600E
  • People with a large or widespread tumour causing significant pressure in the brain or spine, involving more than 3 lobes of the brain, or that has spread outside the skull
  • People who are HIV positive or have Hepatitis B or Hepatitis C
  • People with seizures that are not well controlled
  • People with a history of heart muscle inflammation (myocarditis)
  • People who have received a live vaccine within 30 days before joining
  • People with a known active infection or a condition that weakens the immune system
  • People with significant problems affecting the kidneys, heart, lungs, liver, or other major organs
  • People with serious or unstable ongoing medical conditions
  • Women who are pregnant or breastfeeding
  • People currently taking part in another clinical trial or who have received experimental treatment within 30 days before joining
  • People who are unwilling or unable to complete the treatment and follow-up visits
