Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This phase IV trial studies how well an investigational scan (18F-fluciclovine PET-CT) works for the measurement of therapeutic response in patients with prostate cancer that has spread to other places in the body (metastatic). 18F-fluciclovine is a radioactive substance that is used in this study with PET-CT imaging scans that may help doctors learn about response to standard therapy in patients with prostate cancer.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

PRIMARY OBJECTIVE:

I. Evaluate metabolic response by fluciclovine F18 (18F-fluciclovine) PET qualitatively and semi-quantitatively with standardized uptake values (SUV) following androgen deprivation therapy (ADT) plus abiraterone at 22-28 weeks (+/- 4 weeks), and correlate the findings with size changes as defined by conventional imaging and prostate-specific antigen (PSA) response.

SECONDARY OBJECTIVES:

I. To correlate pelvic 18F-fluciclovine PET imaging findings with pathologic findings at radical prostatectomy and pelvic lymph node dissection to determine 18F-fluciclovine PET imaging sensitivity and specificity for pelvic lymph node cancer involvement.

II. To evaluate 18F-fluciclovine PET imaging response and its correlation with progression free survival (defined by Prostate Cancer Working Group 2 \[PCWG2\] criteria).

III. To determine if sites of progressive disease develop at the initial/prior site (diagnostic site) of metastases or in newly developed sites at the time of metastatic progression.

IV. To evaluate metabolic response by 18F-fluciclovine PET semi-quantitatively with target to blood pool ratio (TBR) following ADT plus abiraterone at 22-28 weeks (+/- 4 weeks), and correlate the findings with size changes as defined by conventional imaging and PSA response.

OUTLINE:

Within 4 weeks before starting standard systemic therapy (SST), patients receive fluciclovine F18 intravenously (IV) then undergo a PET-CT scan over 30 minutes. Within 22-28 weeks after starting SST, patients receive fluciclovine F18 IV and undergo a second PET-CT scan over 30 minutes.
