Aktiver Komparator: Group A: Baseline PSMA PET/CT only with standard of care bicalutamide
Patients will undergo baseline PSMA PET/CT (PET1) with 18F-rhPSMA-7.3 (F-18 flotufolastat, Posluma). After the 18F-rhPSMA-7.3 injection, patients will undergo research imaging consisting of 5 minutes of PET imaging, followed by routine imaging at 60 minutes after 18F-rhPSMA-7.3 injection. Patients will have blood collected for PROSTest and PSA within 1 day of completion of PET1. Following PET1, patients will initiate standard of care bicalutamide for a minimum of 14 days, with the first dose taken the day after PET1. Patients will undergo a 90 day follow-up visit (relative to PET1) for collection of blood for PROSTest and PSA. |
Bicalutamide is a non-steroidal androgen receptor inhibitor administered as a once a day pill taken orally.
This is given as standard of care.
Andere Namen:
Patients will undergo prostate-specific membrane antigen Positron Emission Tomography-Computed Tomography (PSMA PET-CT) imaging.
Each PSMA PET-CT session will consist of 5 minutes of dynamic imaging conducted via the Biograph Vision Quadra PET-CT, a whole-body PET-CT scanner.
Andere Namen:
Radioactive diagnostic agent for intravenous use.
Andere Namen:
PROSTest is a novel, blood-based qPCR assay that assesses gene expression to diagnose PCa and predict patient outcomes to different treatments.

Experimental: Group B: PSMA PET/CT after 2 weeks of standard of care bicalutamide
Patients will undergo baseline PSMA PET/CT (PET1) with 18F-rhPSMA-7.3 (F-18 flotufolastat, Posluma). After the 18F-rhPSMA-7.3 injection, patients will undergo research imaging consisting of 5 minutes of PET imaging, followed by routine imaging at 60 minutes after 18F-rhPSMA-7.3 injection. Patients will have blood collected for PROSTest and PSA within 1 day of completion of PET1. Following PET1, patients will initiate standard of care bicalutamide for a minimum of 14 days, with the first dose taken the day after PET1 and will undergo a research PSMA PET/CT (PET2) on Day 14 (±3 days). The research PSMA PET/CT (PET2) will follow the same imaging procedures as the baseline PET. Patients will undergo a 90 day follow-up visit (relative to PET1) for collection of blood for PROSTest and PSA. |

Group B only: Lesion detection rates between PET1 and PET2.
Zeitfenster: Baseline and 14 days after start of bicalutamide treatment (total estimated time 14 days)
|
Differences in lesion detection rates between Group B PET1 and PET2 will be analyzed by McNemar's test.
Lesion detection rates will be reported by Group B patients at PET1 and PET2 scans and by the two scan sets (first 5 minutes and at 60 minutes post 18F-rhPSMA-7.3
injection).

Group A and B: Number of lesions detected on early scan versus delayed scan
Zeitfenster: At baseline and 14 days after start of bicalutamid treatment (total estimated time is 14 days)
|
The total number of lesions detected per patient will be summarized as counts.
The number of lesions will be summarized by descriptive statistics for all patients at PET1, Group A patients at PET1, Group B patients at PET1, and Group B patients at PET2 and for each, by the two scan sets (early scan = first 5 minutes and at delayed scan = 60 minutes post 18F-rhPSMA-7.3
injection).

|
Group A and B: Correlation between PSA response and PROSTest after radiation therapy
Zeitfenster: Through day 90
|
The correlation between PSA response and PROSTest after radiation therapy will be analyzed in Group A versus Group B. The results will be reported as a two-sample t-test or Wilcoxon sum rank test.
|
Through day 90

|
Group A and B: Comparison of PSA response in patients who are treated with radiation vs. those treated with radiation
Zeitfenster: Through day 90
|
The comparison of PSA response will be analyzed in patients who are treated with radiation based on results of the PET2 versus those treated with radiation based on the results of PET1.
The comparison will be reported as the results of a two-sample t-test or Wilcoxon sum rank test.
