Copper Cu-64 TP3805 PET/CT in Imaging Patients With Urothelial Cancer Undergoing Surgery or Biopsy

Early Phase 1
Completed
Conditions
Urothelial Carcinoma
Bladder Urothelial Carcinoma
Interventions
Procedure: Positron Emission Tomography
Procedure: Computed Tomography
Registration Number
NCT03039413
Lead Sponsor
Sidney Kimmel Cancer Center at Thomas Jefferson University
Brief Summary

This pilot clinical trial studies how well copper Cu-64 TP3805 positron emission tomography (PET)/computed tomography (CT) works in imaging patients with urothelial cancer undergoing surgery or biopsy. Radioactive tracers, such as copper Cu-64 TP3805, may bind to tumor cells. PET/CT imaging performed with copper Cu-64 TP3805 may be a better way to detect urothelial cancer.

Detailed Description

PRIMARY OBJECTIVES:

I. To determine if copper Cu-64 TP3805 (Cu-64-TP3805) shall image urothelial carcinoma (UC) as confirmed by postsurgical or biopsy histology.

SECONDARY OBJECTIVES:

I. To determine blood clearance of Cu-64-TP3805. II. To determine in vivo stability of Cu-64-TP3805.

TERTIARY:

I. To determine if Cu-64-TP3805 is bound to malignant cells and if it is internalized.

Diagnostic (Copper Cu 64 TP3805 PET/CT)Copper Cu 64 TP3805Patients receive copper Cu 64 TP3805 IV and undergo PET/CT after 60 minutes. Patients then undergo standard of care cystectomy and/or biopsy 1 to 4 weeks later.
Diagnostic (Copper Cu 64 TP3805 PET/CT)Positron Emission TomographyPatients receive copper Cu 64 TP3805 IV and undergo PET/CT after 60 minutes. Patients then undergo standard of care cystectomy and/or biopsy 1 to 4 weeks later.
Diagnostic (Copper Cu 64 TP3805 PET/CT)Computed TomographyPatients receive copper Cu 64 TP3805 IV and undergo PET/CT after 60 minutes. Patients then undergo standard of care cystectomy and/or biopsy 1 to 4 weeks later.
Primary Outcome Measures
NameTimeMethod
Feasibility of Cu-64-TP3805 to detect UC as determined by post-surgical histologyUp to 4 weeks post-intervention

For imaging, positive lesions will be deemed those which shall have standard uptake volume of 1.1 or greater. The results shall be correlated with post-surgical histology

Secondary Outcome Measures
NameTimeMethod
Radioactivity internalization of copper Cu 64 TP3805 as analyzed in centrifuged urine samplesUp to 120 minutes post injection

Radioactivity associated with supernatant containing cell cytoplasmic component to and cell membrane button shall be counted and their respective percentage shall be determined.

Blood clearance defined as the point at which radioactivity decreases to 50% of the initial valueUp to 120 minutes post injection

The blood clearance time from all subjects shall be averaged with standard error of the mean.
