Description of intervention(s) / exposure
This Study is a Open label , non randomized prospective pilot.

We plan to conduct a prospective, observational, pilot study on 10 consecutively recruited patients with known metastatic prostate cancer, on the basis of current accepted diagnostic criteria.
Eligible patients will be referred by their Oncologist to our Pet CT department.
A member of the Research team will contact those patients to confirm eligibility and willingness to participate. Once patients have been recruited they will undergo a PET CT scan using [68Ga]Ga-FAPI.

Eligible patients would have undergone assessment for lutetium therapy as standard care. Part of this assessment will include 2 types of PETCTs: 68Ga- PSMA and FDG.
Patients will be invited to the study must have undergone lutetium therapy suitability assessment no longer than 3 months prior to the FAPI PET.

All study activity will be carried out at Mercy Radiology, Epsom branch.

Patients will receive 1 dose of [68Ga]Ga-FAPI before their PET scan. Average radiation dose of 260MBq. The Agent will be administered intravenously under the supervision of the radiologist by a suitably trained member of staff.
So far there is no known adverse effects of FAPI serious or otherwise
The radiation exposure is considerably lower than imaging agents currently used
Patients can expect a single visit to our PETCT department.
The study visit will last approximately 2 hours

Diagnosis / Prognosis
Comparator / control treatment
No Control group
Please note we are not evaluating or comparing FDG PET with 68Ga-PSMA PET.
We are assessing the feasibility of a larger scale trial on the usefulness of FAPI PETCT in prostrate cancer patients
Control group
Uncontrolled

Outcomes
Primary outcome [1] 333107 0
Patients’ scans will be assessed following completion of FDG PET, 68Ga-PSMA PET and FAPI PET. Patients not progressing to all three scans following consent to participate will be recorded.
Timepoint [1] 333107 0
Primary endpoint will be achieved at the end of the study as cumulative data is essential to assess outcome
Primary outcome [2] 333735 0
Feasibility of a larger multicenter trial. This will include: Patient screening rate (number of screened over time); enrolment rate (number of enrolled over time); screening failure (total number of enrolled/total number of screened); reasons for screening failure, retention rate (number of patients completing the study /number of patients enrolled) and reasons for discontinuing the study before completion.
Data will be obtained through recruitment logs and patient study records
Timepoint [2] 333735 0
Primary endpoint will be achieved at the end of the study as cumulative data is essential to assess outcome
Secondary outcome [1] 415851 0
Number of patients with uptake at [68Ga]Ga-FAPI PET/CT deemed diagnostic by study criteria This information will help determine if [68Ga]Ga-FAPI could be a more effective agent in detecting the extent of disease and discordant disease
Timepoint [1] 415851 0
24 hours post FAPI PETCT
