Inclusion Criteria:

Patients with histologically confirmed GBM following surgical resection of their tumour and are eligible for adjuvant chemoradiation with the following characteristics will be recruited:

• - Age ≥18.

• - World Health Organisation (WHO) performance status 0 - 2.

• - If female, the subject is either post-menopausal (at least 1 year), or surgically sterilized (has had a documented bilateral oophorectomy and/or documented hysterectomy for at least 2 years), or if of childbearing potential, must have a negative urine beta human chorionic gonadotropin (beta-HCG) pregnancy test done at initial screening and on the day of tracer administration.

The result of the pregnancy test must be known before administration of 18F-FPIA injection.

• - The subject is able and willing to comply with study procedures, and signed and dated informed consent is obtained.

• - The subject has a satisfactory medical history as judged by the investigator with no significant co-morbidities, physical examination, and vital signs findings during the screening period (from 21 days before administration).

• - The subject's clinical and laboratory tests are within normal limits and/or considered clinically insignificant.

Exclusion Criteria:

• - The subject has received any chemotherapy, immunotherapy, biologic therapy or investigational therapy within 14 days or five half-lives of a drug (whichever is longer) prior to the first dose of 18F-FPIA injection.

• - The subject is pregnant or lactating.

• - Any other chronic illness that will or musculoskeletal condition that would not allow comfortable performance of a static PET study.

• - The subject has received another investigational radioactive tracer within 1 month before administration of 18F-FPIA injection.

• - Unsatisfactory renal function (epidermal growth factor receptor, eGFR<60) within 3 months of [18F]FPIA injection.

Twenty evaluable participants with histologically confirmed glioblastoma multiforme (GBM) following surgical resection that are due to undergo treatment with chemoradiotherapy (CRT) will be enrolled into the study. The patients invited to participate in the study will provide written informed consent, but will only undergo 18F-FPIA positron emission tomography-computerised tomography (PET-CT) imaging once they have satisfied the inclusion and exclusion criteria. Once these criteria have been satisfied, eligible participants will proceed with a 18F-FPIA PET-CT post-surgical resection/prior to CRT, mid-therapy (~4-6 weeks from the start of CRT, and at the end of CRT treatment (~10-14 weeks from the end of treatment). All the participants that are enrolled in the study will have undergone surgical resection as part of their routine clinical care from which a tissue diagnosis will be confirmed. On the scan date, the participants will undergo a blood test to measure plasma concentrations of carnitine. During the scan, a single dose of 18F-FPIA (maximum, 370MBq) intravenous (IV) will be administered to the participant followed by a whole brain static PET-CT scan 40 minutes post-injection.
