Description of intervention(s) / exposure
This study aims to compare two PET radiotracers in primary and recurrent prostate cancer.
The protein PSMA (Prostate Specific Membrane Antigen) is commonly present in high levels in prostate cancer, and this study uses two radiotracers that specifically target PSMA to identify sites of prostate cancer (routinely-used 68Ga-PSMA-11 and the newer 18F-PSMA-1007).

All patients will have two PSMA PET-CT scans, performed within 4-7 days of each other. The scan order will be randomised but unblinded:
One 68Ga-PSMA-11 PET-CT scan, with tracer injected intravenously 50 minutes prior to scanning. This is a routine scan that will be reported as per standard of care. The dose of this scan will be 180-250MBq.
One 18F-PSMA-1007 PET-CT scan, with tracer injected intravenously 3 hours prior to scanning. This scan is investigational, and will not be reported. The dose of this scan will be 180-360MBq

An optional 'kinetics' subcohort of 40 patients who agree to participate will have additional PET-CT scans, at 1h, 2h, and 3h after injection with the 18F-PSMA tracer, in order to measure the kinetics of tracer localisation. No additional time or tracer injection is required, but patients will be exposed to a small amount of extra radiation from the ultra low dose CT scans involved with the extra scanning procedures.

Patients will be followed up three months post scanning for subsequent treatment, and for histopathological validation of imaging if patients had subsequent lymph node dissection.

Outcomes
Primary outcome [1] 319423 0
The primary outcome will be the number of lesions detected with each PET tracer, and overlap of the detected sites of disease.
Timepoint [1] 319423 0
50 minutes following injection of the 68Ga-PSMA tracer; 180 minutes following injection of the 18F-PSMA tracer.
Primary outcome [2] 319424 0
SUVmax of lesions detected by each scanning modality
Timepoint [2] 319424 0
50 minutes following injection of the 68Ga-PSMA tracer; 180 minutes following injection of the 18F-PSMA tracer.
Secondary outcome [1] 368093 0
Sensitivity/specificity of lesion detection for each imaging modality. Where available, for patients who undergo subsequent lymph node dissection, lesions detected on each scan will be compared to lesions detected pathologically. These will be categorised as false positive/negative or true positive/negative, to determine specificity and sensitivity.
Timepoint [1] 368093 0
Lymph node dissections within 3 months after scanning.
Secondary outcome [2] 368116 0
Examine the kinetics of 18F-PSMA uptake in the kinetics subcohort of patients, by measurement of tracer uptake (SUVmax) of lesions and organs (bladder, liver, kidneys) over time (1h, 2h, 3h after tracer injection), as measured on each PET scan.
Timepoint [2] 368116 0
60, 120, and 180 minutes following injection of the 18F-PSMA tracer

Eligibility
Key inclusion criteria
1) be >= 18 years of age
2) have a confirmed diagnosis of prostate cancer from:
a) a biopsy-confirmed diagnosis of prostate cancer;
b) suspected recurrent prostate cancer after primary treatment; there is no study-specific PSA threshold value for biochemical recurrence, but rather the assessment of suspected recurrence is left to the referring Dr;
3) have a management question, for which a PSMA PET-CT scan is indicated and,
4) be willing to have two PET-CT scans on separate days.

Summary
Brief summary
The purpose of this study is to compare two different types of PET-CT scans (Positron Emission Tomography - Computed Tomography) for imaging prostate cancer.

Who is it for?
You may be eligible for this study if you are aged 18 or over, have a confirmed diagnosis of prostate cancer or suspected prostate cancer recurrence, and your doctor believes that a PET scan would be helpful for treatment decisions.

Study details
All participants in this study will have two PET scans. One will be a routine standard-of-care scan (68Ga-PSMA), and the other will be a newer investigational scan (18F-PSMA).
Before each scan, participants will be injected in the arm with a different tracer chemical. These tracer chemicals will localise to the prostate cancer. For one scan, this will happen 50 minutes before, and in the other it will happen 3 hours before.
An optional subgroup will have additional scans (but no additional injections) on the day of one of these scans. The scans on this day will be one hour, two hours, and three hours after the injection. This will measure how the injected tracer moves through the body at different times.

It is hoped this research will demonstrate the two tracers are equivalent, or the newer one is better. This may provide additional imaging options for patients with prostate cancer.
