Prostate Cancer Clinical Trial

FTT PET/CT in Metastatic Prostate Cancer

Summary

Up to 30 men with metastatic prostate cancer will undergo up to 2 FTT PET/CT scans to look at PARP activity in sites of known cancer. Subjects will undergo a baseline scan prior to starting new therapy and a second, optional, post-therapy scan 1-21 days after the start of treatment. Tissue from a clinical or research biopsy will be compared to imaging measures, if available.

Full Description

Up to 30 evaluable patients with a histological diagnosis of prostate cancer with clinical evidence of metastatic disease who are being considered for new therapy or for a change in therapy with a PARP inhibitor, androgen deprivation therapy, and/or chemotherapy as part of their clinical care will be enrolled in this study. A pre-treatment 18F-FluorThanatrace ([18F]FTT) positron emission tomography/ computed tomography (PET/CT) scan will be done prior to the start of a new therapy regimen. PET/CT imaging will be used to evaluate PARP-1 expression in sites of prostate cancer using the investigational radiotracer [18F]FTT. This is an observational study in that [18F]FTT PET/CT will not be used to direct treatment decisions. While patients and referring physicians will not be blinded to the [18F]FTT PET/CT results, treatment decisions will be made by the treating physicians based upon clinical criteria. After injection of [18F]FTT patients will undergo a skull base to mid-thigh scan, starting at approximately 60 minutes post injection. PET/CT imaging sessions will include an injection of 12 mCi of [18F]FTT intravenously (approximate range for most studies is anticipated to be 8-12 mCi ). of [18F] FTT. Data will be collected to evaluate uptake of [18F]FTT in sites of prostate cancer, which will be compared with PARP-1 expression in tissue, when available. All evaluable patients may start new therapy following the [18F]FTT PET/CT scan. It is expected that due to patient preference and time considerations, approximately 80% will also undergo a second (optional) scan that will be performed approximately 1-21 days after new therapy has started. The second scan is obtained to evaluate whether the initiation of a PARP inhibitor and/or androgen deprivation therapy and/or chemotherapy alters [18F] FTT uptake.
