Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
20-40 % of men will suffer a biochemical recurrence of their prostate cancer after radical prostatectomy, depending on their final pathological staging, defined as a rising PSA \> 0.2 ng/ml.
The ability to more accurately diagnose local recurrence (i.e. pelvis) or oligometastasis may lead to the opportunity of precise therapy of these sites with more durable cancer responses, less morbidity and potential cure in selective men after Radical Prostatectomy.
The ability to diagnose widespread metastatic Prostate Cancer after Radical Prostatectomy, or disease that is inaccessible to local selective therapies would spare these men the cost and morbidity of inappropriate therapy.
The diagnosis of true stage D0 Prostate Cancer (No objective evidence of metastases) in men after Radical Prostatectomy would yield improved overall and disease specific survival if Androgen Deprivation Therapy was initiated at its earliest stage. This would also obviate the need for inappropriate local therapies (i.e. pelvic radiotherapy).
The aim is to compare the detection rate of standard of care (CT Pelvis/Abdomen, MR Pelvis, Bone Scan) with Fluciclovine PET/CT performed on the Vereos Philips Scanner. The study aims to compare the performance of Digital (high resolution) PET to CT/MRI/Bone scan rather than analog (lower resolution) PET. Prior studies have tested analog PET compared to other modalities. One could make an inference that if our study's Digital PET performs better than the performance of Analog PET in those studies, then Digital PET should have a better detection rate than Analog PET. However, investigators are not making a direct comparison between digital and Analog in our comparison.

Compare the detection rate of standard of care (CT Pelvis/Abdomen, MR Pelvis, Bone Scan) with Fluciclovine PET/CT performed on the Vereos Philips Scanner. The study aims to compare the performance of Digital (high resolution) PET to CT/MRI/Bone scan rather than analog (lower resolution) PET. This was reported in Michopoulou S, O'Shaughnessy E, Thomson K, Guy MJ. Discovery Molecular Imaging Digital Ready PET/CT performance evaluation according to the NEMA NU2-2012 standard. Nucl Med Commun. 2018 Nov 27; doi:10.1097/MNM.0000000000000962. Prior studies have tested analog PET compared to other modalities. One could make an inference that if our study's Digital PET performs better than the performance of Analog PET in those studies, then Digital PET should have a better detection rate than Analog PET. However, investigators are not making a direct comparison between digital and Analog in our comparison.
Background:
Fluciclovine F18 (Fluciclovine) has been demonstrated to provide good delineation of recurrence of prostate cancer after definitive therapies (Odewole OA et al 2016). Fluciclovine in conjunction with the high-resolution digital Vereos (Phillips) PET-CT scanner may detect low volume recurrence in the prostatectomy bed or metastatic site (s).
20-40 % of men will suffer a biochemical recurrence of their prostate cancer after radical prostatectomy, depending on their final pathological staging, defined as a rising PSA \> 0.2 ng/ml.
The ability to more accurately diagnose local recurrence (i.e. pelvis) or oligometastasis may lead to the opportunity of precise therapy of these sites with more durable cancer responses, less morbidity and potential cure in selective men after Radical Prostatectomy.
The ability to diagnose widespread metastatic Prostate Cancer after Radical Prostatectomy, or disease that is inaccessible to local selective therapies would spare these men the cost and morbidity of inappropriate therapy.
The diagnosis of true stage D0 Prostate Cancer (No objective evidence of metastases) in men after Radical Prostatectomy would yield improved overall and disease specific survival if Androgen Deprivation Therapy was initiated at its earliest stage. This would also obviate the need for inappropriate local therapies (i.e. pelvic radiotherapy).
Preliminary Studies:
The safety, efficacy, reproducibility, and reliability of Fluciclovine was initially evaluated by the Emory group in men with suspected recurrence of prostate cancer based on rising PSA levels following radical prostatectomy and/or radiotherapy. Fluciclovine's safety, detection rate, and diagnostic performance was further validated in a multi-site data aggregation study using data from Emory, Noway, and Italy.
The performance of Fluciclovine seems to be affected by degree of PSA elevation. Statistically significant difference in performance compared to CT was found at PSA levels \>1 ng/ml. However, at a PSA level of \<1 ng/ml, no statistically significant difference was found by Odewole et al. These findings were independent of PSA doubling time and Gleason Score.
The Bologna study evaluated the concordance between Fluciclovine and C11 Choline scans in patients with median PSA value of 1.44 ng/ml (interquartile range = 0.78 to 2.8 ng/ml).5 The accuracy of Fluciclovine was 38% vs 32% for C11 Choline. In a subsequent Emory study which studied Fluciclovine without a correlative imaging test, Fluciclovine scan detected recurrence in 72% (18/25) of patients with PSA of \<1 ng/ml. However, there was no reconciliation of false positive examinations, as all abnormal radiotracer uptake were deemed a true positive. Performance of Fluciclovine was again noted to improve with increasing PSA levels, at 83% (5/6) for PSA of 1-\<2 ng/ml and 100% (11/11) for PSA\>= 2 ng/ml.
Rationale:
A Fluciclovine scan can detect and localize recurrent prostate cancer. Fluciclovine is an FDA-approved diagnostic imaging agent, also known as a "tracer," which may help determine if and where the prostate cancer has recurred.
Procedures:
Fluciclovine is used as a tracer for a PET/CT scan. Patients will need to prepare for the Fluciclovine (fluciclovine F 18) injection and scan. They will need avoid any significant exercise for at least a full 24 hours prior to Fluciclovine PET/CT scan and not eat or drink for at least 4 hours prior to PET/CT scan (other than small amounts of water for taking medications).
With respect to determining if a finding is true positive, investigators will follow the following process. The research PET scan of each patient and SOC imaging will be read by radiologists blinded to the results of the other test. The results of both will then be reviewed by PI for concordance. If the research PET scan finds sites of disease that were not identified on SOC imaging, the case will be brought to Interdisciplinary UVMMC Genitourinary tumor board. Depending on the site of disease and presence of other concordant sites of metastatic disease between scans, it may have no impact on the SOC treatment. If it is deemed by the UVMMC Genitourinary Tumor Board that it will have a meaningful impact on treatment decisions and the detected lesion is accessible to be safely sampled, the patient will be approached by their treating physician to discuss the discordant findings, their significance, and the rationale behind a biopsy and its impact on their care.
The sampling will then be performed a part of standard-of-care work-up, given that these patients would have been eligible for Fluciclovine PET imaging in this setting, per FDA label. Given the low PSA range of our target population in this study, the likelihood that these lesions would be amenable to sampling using conventional image guidance is low. Therefore, in cases where the research scan finds additional disease that would alter therapy, the decision of whether to act on it will be based on the overall clinical scenario of each patient, and will be decided by the treating team with the support of the UVMMC Genitourinary Tumor Board.
