Copper Cu 64 TP3805 PET in Detecting Cancer in Patients With Prostate Cancer Undergoing Surgery

Phase 1

Completed

• Conditions: Stage IIB Prostate Cancer; Prostate Adenocarcinoma; Stage IV Prostate Cancer; Stage III Prostate Cancer
• Interventions: Radiation: Copper Cu 64 TP3805; Procedure: Positron Emission Tomography; Procedure: Computed Tomography; Procedure: Radical Prostatectomy; Other: Laboratory Biomarker Analysis

• Registration Number: NCT02603965
• Lead Sponsor: Sidney Kimmel Cancer Center at Thomas Jefferson University

Brief Summary

This pilot phase I trial studies copper Cu 64 TP3805 (Cu-64-TP3805) positron emission tomography (PET)/computed tomography (CT) in detecting cancer in patients with prostate cancer undergoing surgery to remove the entire prostate and some of the tissue around it (radical prostatectomy). Many patients with benign lesions must undergo biopsy to test the lesion. Cu-64-TP3805 is a radioactive substance that attaches to cancer cells but not normal cells. PET/CT uses a scanner to make detailed, computerized pictures of areas inside the body where the radioactive substance is lighting up. Using Cu-64-TP3805 PET/CT scans and comparing them with cancer tissue obtained from surgery may help doctors learn whether Cu-64-TP3805 PET/CT can accurately detect prostate lesions and determine whether they are cancerous or benign, which may minimize the need for prostate biopsies.

Detailed Description

PRIMARY OBJECTIVES:

I. To assess the ability of Cu-64-TP3805 to detect prostate cancer (PC) within the prostate gland, as compared with whole mount step-sectioned surgical pathology of the prostate after radical prostatectomy.

OUTLINE:

Patients receive copper Cu 64 TP3805 intravenously (IV) and undergo PET/computed tomography (CT) at 30 minutes and 2 hours post-injection. Patients then undergo radical prostatectomy within 1 to 3 weeks after scans.

After completion of study, patients are followed up at 24 hours.

Group	Intervention	Description
Diagnostic (Cu 64 TP3805 PET/CT)	Positron Emission Tomography	Patients receive copper Cu 64 TP3805 IV and undergo PET/CT at 30 minutes and 2 hours post-injection. Patients then undergo radical prostatectomy within 1 to 3 weeks after scans.
Diagnostic (Cu 64 TP3805 PET/CT)	Copper Cu 64 TP3805	Patients receive copper Cu 64 TP3805 IV and undergo PET/CT at 30 minutes and 2 hours post-injection. Patients then undergo radical prostatectomy within 1 to 3 weeks after scans.
Diagnostic (Cu 64 TP3805 PET/CT)	Computed Tomography	Patients receive copper Cu 64 TP3805 IV and undergo PET/CT at 30 minutes and 2 hours post-injection. Patients then undergo radical prostatectomy within 1 to 3 weeks after scans.
Diagnostic (Cu 64 TP3805 PET/CT)	Laboratory Biomarker Analysis	Patients receive copper Cu 64 TP3805 IV and undergo PET/CT at 30 minutes and 2 hours post-injection. Patients then undergo radical prostatectomy within 1 to 3 weeks after scans.
Diagnostic (Cu 64 TP3805 PET/CT)	Radical Prostatectomy	Patients receive copper Cu 64 TP3805 IV and undergo PET/CT at 30 minutes and 2 hours post-injection. Patients then undergo radical prostatectomy within 1 to 3 weeks after scans.

Primary Outcome Measures

Name	Time	Method
Detection rate of Cu-64 PET imaging of PC	Baseline (at time of surgery)	The proportion of lesions detected with Cu-64 PET will be determined and compared with tumor maps derived from the whole mount step sectioned surgical pathology analysis of the radical prostatectomy specimen after surgery. 95% confidence intervals will be calculated. As a secondary analysis, a generalized estimating equations will be utilized to account for multiple lesions in an individual patient.
Incidence of adverse events	Up to 30 days post Cu-64-TP3805 injection procedure
