A Pilot Study of 18F-DCFBC PET/CT in Prostate Cancer

Background:
- Prostate cancer is the second leading cause of cancer deaths in American men. A chemical called a radiotracer helps doctors get images of this type of cancer. Researchers want to test a radiotracer called N-[N-[(S)-1,3-dicarboxypropyl]carbamoyl]-4-(18)F-fluorobenzyl-L-cysteine ((18)F-DCFBC) (18F-DCFBC).
Objective:
- To see if the radiotracer 18F-DCFBC can identify sites of prostate cancer in the body.
Eligibility:
- Men ages 18 and over with prostate cancer. The cancer must be newly diagnosed, have relapsed, or has spread outside the prostate.
Design:
* Participants will be screened with physical exam and medical history. They will give a blood sample.
* Participants will be divided into three groups.
Group 1: people with cancer only in the prostate scheduled for surgical prostate removal or biopsy at National Institutes of Health (NIH).
Group 2: people who had their prostate removed or had radiation therapy and now have a rising prostate-specific antigen (PSA) without other signs of disease.
Group 3: people whose cancer has spread to other areas of the body.
* Participants will have 18F-DCFBC injected into a vein then imaged in a positron emission tomography (PET)/computed tomography (CT) camera. During the scans, they will lie on their back on the scanner table.
* Group 1 will have a magnetic resonance imaging (MRI) scan. A tube will be placed in the rectum. Coils may be wrapped around the outside of the pelvis. Participants will have a contrast agent injected through an intravenous line.
* Group 3 will have another PET/CT scan with a different radiotracer, 18F NaF, within 21 days of the 18F-DCFBC scan to look for prostate cancer in the bone.
* Group 3 will repeat the two PET/CT scans 4-6 months after the initial scans.
* A few days after each scan, participants will be contacted for follow-up.

Evaluation of PSMA-based PET as an Imaging Biomarker of Primary Prostate Cancer

The objective of this study is to evaluate a radiolabeled urea-based small molecule inhibitor of prostate-specific membrane antigen (PSMA), [18F]DCFBC (DCFBC), as a PET imaging biomarker of prostate cancer detection and aggressiveness at initial diagnosis. PSMA is a well characterized histological marker of prostate cancer tumor aggressiveness but a quantitative non-invasive method for PSMA detection and monitoring is not currently available. Development of such an imaging biomarker would be useful to differentiate indolent from aggressive prostate cancer phenotypes and allow for selection of appropriate risk adaptive therapies. The investigators preliminary first-in-human studies demonstrate high specific DCFBC uptake in metastatic prostate cancer and feasibility for prostate cancer imaging. The investigators propose to study patients initially diagnosed with biopsy-positive prostate cancer to determine if DCFBC uptake and location by PET imaging will be positively correlated with prostate cancer by prostatectomy tissue step-section analysis. DCFBC uptake at sites of suspected metastatic disease will be compared to conventional imaging modalities (CT, bone scan) and biopsy results when available. In addition, DCFBC-PET uptake quantification will be compared with expression levels of PSMA and other prostate cancer relevant markers (PSA, Ki-67, TMPRSS2-ERG) by prostate tissue immunohistochemistry analysis and compared with clinical prognostic markers (PSA, Gleason score, clinical stage, Partin tables derived prediction of pathologic stage).

Electrostatic Effects Accelerate Decatungstate-Catalyzed C–H Fluorination Using [¹⁸F]- and [¹⁹F]NFSI in Small Molecules and Peptide Mimics

作者: Martin, Rainer E. ; Warren, Jeffrey J. ; Yuan, Zheliang ; Yang, Hua ; Britton, Robert ; Weber, David S. ; Malik, Noeen ; Schaffer, Paul ; Čolović, Milena ; Wilson, Darryl ; Bénard, François

The site-selective fluorination of unactivated C(sp³)-H bonds provides unique opportunities to rapidly alter drug properties or generate radiotracers for positron emission tomog. (PET) imaging.Toward this goal, photoactivated decatungstate (DT) is capable of generating carbon radicals through hydrogen atom transfer that subsequently undergo fluorination by reaction with N-fluorobenzenesulfonimide (NFSI) or [¹⁸F]NFSI.This process enables C(sp³)-H fluorination of a wide range of aliphatic compounds, though reaction rates can be highly variable and limit applications in radiotracer synthesis.Here, we demonstrate that cationic ammonium functions in aliphatic mols. promote formation of a precursor complex with DT that significantly increases the rate of C-H abstraction.The general utility of this rate-accelerating electrostatic effect is demonstrated on more than 30 ammonium-containing mols., including amino acids, heterocycles, and pseudopeptides.Moreover, this effect is highlighted in the rapid production of [¹⁸F]Glu-U-FHLeu, a ¹⁸F-labeled prostate specific membrane antigen (PSMA)-binding ligand.

PURPOSE:

To assess the ability of (N-[N-[(S)-1,3-dicarboxypropyl]carbamoyl]-4-F-fluorobenzyl-L-cysteine) (F-DCFBC), a prostate-specific membrane antigen-targeted PET agent, to detect localized prostate cancer lesions in correlation with multiparametric MRI (mpMRI) and histopathology.

METHODS:

This Health Insurance Portability and Accountability Act of 1996-compliant, prospective, institutional review board-approved study included 13 evaluable patients with localized prostate cancer (median age, 62.8 years [range, 51-74 years]; median prostate-specific antigen, 37.5 ng/dL [range, 3.26-216 ng/dL]). Patients underwent mpMRI and F-DCFBC PET/CT within a 3 months' window. Lesions seen on mpMRI were biopsied under transrectal ultrasound/MRI fusion-guided biopsy, or a radical prostatectomy was performed. F-DCFBC PET/CT and mpMRI were evaluated blinded and separately for tumor detection on a lesion basis. For PET image analysis, MRI and F-DCFBC PET images were fused by using software registration; imaging findings were correlated with histology, and uptake of F-DCFBC in tumors was compared with uptake in benign prostatic hyperplasia nodules and normal peripheral zone tissue using the 80% threshold SUVmax.

RESULTS:

A total of 25 tumor foci (mean size, 1.8 cm; median size, 1.5 cm; range, 0.6-4.7 cm) were histopathologically identified in 13 patients. Sensitivity rates of F-DCFBC PET/CT and mpMRI were 36% and 96%, respectively, for all tumors. For index lesions, the largest tumor with highest Gleason score, sensitivity rates of F-DCFBC PET/CT and mpMRI were 61.5% and 92%, respectively. The average SUVmax for primary prostate cancer was higher (5.8 ± 4.4) than that of benign prostatic hyperplasia nodules (2.1 ± 0.3) or that of normal prostate tissue (2.1 ± 0.4) at 1 hour postinjection (P = 0.0033).

CONCLUSIONS:

The majority of index prostate cancers are detected with F-DCFBC PET/CT, and this may be a prognostic indicator based on uptake and staging. However, for detecting prostate cancer with high sensitivity, it is important to combine prostate-specific membrane antigen PET/CT with mpMRI.

Carducci ; Barbara S. Slusher ; Akimosa Jeffrey-Kwanisai ; Kenneth L. Gage ; Martin G. Pomper ; Ronald Rodriguez ; George Sgouros ; Srinivasan Senthamizhchelvan

METHODS:

Five patients with radiologic evidence of metastatic PCa were studied after the intravenous administration of 370 MBq (10 mCi) of (18)F-DCFBC. Serial PET was performed until 2 h after administration. Time-activity curves were generated for selected normal tissues and metastatic foci. Radiation dose estimates were calculated using OLINDA/EXM 1.1.

RESULTS:

Most vascular organs demonstrated a slow decrease in radioactivity concentration over time consistent with clearance from the blood pool, with primarily urinary radiotracer excretion. Thirty-two PET-positive suspected metastatic sites were identified, with 21 concordant on both PET and conventional imaging for abnormal findings compatible with metastatic disease. Of the 11 PET-positive sites not identified on conventional imaging, most were within the bone and could be considered suggestive for the detection of early bone metastases, although further validation is needed. The highest mean absorbed dose per unit administered radioactivity (μGy/MBq) was in the bladder wall (32.4), and the resultant effective dose was 19.9 ± 1.34 μSv/MBq (mean ± SD).

CONCLUSION:

Although further studies are needed for validation, our findings demonstrate the potential of (18)F-DCFBC as a new positron-emitting imaging agent for the detection of metastatic PCa. This study also provides dose estimates for (18)F-DCFBC that are comparable to those of other PET radiopharmaceuticals such as (18)F-FDG.
