Gender | All |
Age group | 18 Years to 65 Years |
Eligibility | Inclusion Criteria: 1. Understand and voluntarily sign the informed consent form prior to any study related procedure and/or assessments being conducted. 2. Are Male or Female, and aged 18-65 years of age inclusive, at the time of signing the informed consent. 3. Have histologically confirmed intracranial glioblastoma (per WHO 2021 definition) following surgical resection. Tumours primarily localised in the infratentorial compartment will be excluded. 4. Have had prior surgery for glioblastoma, but no systemic therapy or radiation therapy for GBM. 5. Have a Karnofsky Performance Status =70. 6. Plan to begin chemoradiation therapy 3-6 weeks after surgical resection with Stupp regimen. 7. Have adequate organ function at Screening: 7.1 Bone marrow: 7.1.1 Leukocytes =3,000/mL 7.1.2 Absolute neutrophil count =1500/mL 7.1.3 Platelets =100,000/mL 7.1.4 Haemoglobin =9g/dL 7.2 Liver function: 7.2.1 Total bilirubin =1.5×the upper limit of normal (ULN). For patients with known Gilbert's Syndrome =3×ULN is permitted 7.2.2 Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) =2.5×ULN 7.3 Renal function: 7.3.1 Serum/plasma creatinine =1.5×ULN or creatinine clearance =50 mL/min 8. Have at least 6 slides without staining or a tissue block (frozen or paraffin-embedded) available from a previous biopsy or surgery (tumour sample previously archived). 9. Have the capacity to understand the study and be able and willing to comply with all protocol requirements, including compliance with the radiation protection guidelines (including hospital admissions and isolation) that are applied by the treating institution to protect their contacts and the public. 10. Agree to practice adequate precautions to prevent pregnancy to avoid potential problems associated with radiation exposure to the unborn child. 11. Females must have a negative pregnancy test at screening and on dosing day, must not be lactating. Exclusion Criteria: 1. Are unable to provide signed informed consent 2. Have had prior treatment for glioma, excluding surgery. 3. Are unable to undergo contrast-enhanced MRI. 4. Intend to be treated with tumor-treating fields prior to progression. 5. Have a history or evidence of delayed-type hypersensitivity (DTH)-dependent chronic infection (e.g., tuberculosis, systemic fungal or parasitic infection), potentially exacerbating under systemic corticoid therapy. 6. Have a known history of allergy TMZ, any excipient in the study medication or any other intravenously administered human proteins/peptides/antibodies. 7. Have haemostaseologic conditions, precluding catheterisation or invasive procedures. 8. Have phenylketonuria 9. Have a medically documented history of or active major depressive episode, bipolar disorder (I or II), obsessive-compulsive disorder, schizophrenia, a history of suicidal attempt or ideation, or homicidal ideation (e.g., risk of doing harm to self or others), or patients with active severe personality disorders. 10. Major trauma including major surgery (such as abdominal/cardiac/thoracic surgery) within 3 weeks of administration of study treatment except surgery on primary tumour. 11. Pregnant, breastfeeding or planning to get pregnant during the duration of the study. 12. Requirement of chronic administration of high dose corticosteroids or other immunosuppressant drugs. Limited or occasional use of corticosteroids to treat or prevent acute adverse reactions is not considered an exclusion criterion. 13. Have presence of active and uncontrolled infections or other severe concurrent disease, which, in the opinion of the investigator, would place the participant at undue risk or unable to comply with study requirements. HIV-positive participants may be included in the study if they are on a stable dose of anti-retroviral therapy. 14. Have concurrent malignancies unless the patient has been disease-free without intervention for at least 2 years. 15. Have taken growth factors or immunomodulatory agents within 7 days prior to the administration of study treatment. 16. Have serious, non-healing wound, ulcer, or bone fracture. 17. Have a requirement of concurrent use of other anti-cancer treatments or agents other than study medication. 18. Have received any other IMP within 90 days prior to the planned administration of study drug. 19. Have uncontrolled Hashimoto's or Grave's disease 20. Have on-going and unresolved Grade = 1 AEs following surgical resection |
