Study information
Scientific title
Evaluation of PSMA (68Ga) PET/CT as a tool to guide treatment choice in patients with high risk prostate cancer
Acronym
PSMA Imaging
Study hypothesis
The aim of this study is to evaluate if the PSMA PET/CT scan will identify whether or not the cancer has spread to the lymph nodes. This will mean that for future patients, whose cancer without evidence of having spread to the lymph nodes, can have less extensive surgery. They will not have to have their pelvic lymph nodes removed at the time of surgery

Study design
PSMA Imaging is a feasibility study looking at patients who have high risk prostate cancer (in the absence of clinical evidence for distant metastasis) opting for surgical intervention with radical prostatectomy and extended pelvic lymphadenectomy. 60 patients will be recruited over a 6 month period from 4 centres within the United Kingdom.
Patients who have signed informed consent and who have met all eligibility criteria will be enrolled into the trial.
Once enrolled all patients will have a PSMA PET/CT scan prior to (and within 2 weeks of) surgery, in addition to standard of care imaging as per local clinical practice.

Condition
Prostate Cancer
Intervention
Participants attend a screening visit. Informed consent, medical history, a physical examination and a number of blood tests are taken at this visit.
Participants receive only one extra scan (out with any other standard care scans required) which is called a (Ga68) PSMA PET/CT scan. Participants then have their elective surgery as schedules.
Participants attend a six week follow up visit. A physical examination and the same blood tests will be done again six weeks after their surgery. The surgeon will also discuss the outcome of the surgery that they have had and will discuss any future management of care.

Primary outcome measures
1.SUVmax is measured for each lesion using the 68Ga-PSMA PET/CT within 2 weeks of a scheduled RP and ePLND this will be used along with independent nuclear medicine physicians to determine the sensitivity, specificity, positive predictive and negative predictive values of 68Ga-THP-PSMA imaging in detecting pelvic nodal metastasis
2. The establishment of best practice will be measured by the production of protocols for multi-centre application of PSMA PET/CT imaging
Secondary outcome measures
1. The use of novel 68Ga-THP-PSMA radiopharmaceutical is measured using the successful assessment of 60 patients through to the end of study and inclusion in the study analysis
2. Feasibility of a future large scale randomised controlled trial is measured using recruitment of 60 patients into the study within the proposed timelines and by the development of quality assurance measures across the study team/network
3. The development of a platform to carry out RCT to study the usefulness of novel imaging/biomarkers for evidence-based treatment decisions in patients at risk of pelvic nodal prostate cancer is measured by the future development of RCT’s in this area.
