Brief Summary

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

TRDC002 uses a radioactive form (64Cu) to trace the PSMA positive prostate cancer. The purpose of this study is to investigate TRDC002 as a PSMA PET tracer to localize PSMA positive lesions in adult patients with recurrent or metastatic prostate cancer. We plan to assess the PSMA PET/CT image quality following administration of two dose levels of TRDC002 to determine an acceptable dose and optimal acquisition time for obtaining diagnostic quality PET/CT images. The safety and tolerability, PK, biodistribution, dosimetry of TRDC002 will also be evaluated in this study.

Detailed Description

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

This is a prospective, randomized, open-label, phase I study to evaluate safety and tolerability, PK, biodistribution, dosimetry and preliminary efficacy of TRDC002 for PET/CT imaging in participants with PSMA-positive recurrent or metastatic prostate cancer compared with CRS.

At screening, the participants will be assessed for eligibility and will undergo PSMA PET to screen PSMA positive patients.

Eligible participants with recurrent or metastatic prostate cancer will be randomized to receive a single dose of either 4 or 6 mCi of TRDC002 intravenously. Whole-body PET/CT images will be acquired at 1hr, 4hr, 7hr, and 24hr post-injection to observe radiation absorbed dose and pharmacokinetics. Independent review committee (IRC) will evaluate the quality of PET images to determine an acceptable dose and optimal acquisition time for PET scan, and preliminary efficacy compared with Composite Reference Standard (CRS) based on CT/MRI with contrast and bone scan.
