Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Treatment: Drugs - Copper-64 labelled SAR-Bombesin

Experimental: Male patients with hormone sensitive disease - who demonstrate rising PSA levels (\>0.2ng/ml) following definitive therapy and a negative 68Ga-PSMA-11 PET scan (defined as SUV max \< 3);

Experimental: Male patients with metastatic castration resistant prostate cancer - being considered for 177Lu-PSMA-617 therapy with known metastatic disease on conventional imaging and sites with low PSMA expression on 68Ga-PSMA-11 PET scan (defined as SUV max \<10) in the presence of disease volume of \> 1cm.


Treatment: Drugs: Copper-64 labelled SAR-Bombesin
radiolabeled antagonist analog of bombesin for the diagnosis and treatment of gastrin releasing peptide receptor (GRPR)-positive tumors in adults. The product is Copper-64 labelled SAR-Bombesin (Cu-SAR-BBN). Cu-SAR-BBN uses radioactive forms (radionuclide) of copper, copper-64 (64Cu) to image cancers using Positron Emission Tomography (PET) and then copper-67 (67Cu) for therapy by internal beta radiation. 64Cu-SAR-BBN has 3 basic components; the radionuclide (64Cu), bound via MeCOSar (a bifunctional metal chelator, SAR) to a bombesin analog that targets GRPR.
