89Zr-TLX250 is under clinical development as a diagnostic agent targeting clear cell renal cell carcinoma.


This is a confirmatory, prospective, open-label, multi-centre phase 3 study to evaluate sensitivity and specificity of 89Zr-TLX250 Positron Emission Tomography/Computed Tomography (PET/CT) imaging to non-invasively detect clear cell renal cell cancer (ccRCC) in adult patients with indeterminate renal masses (IRM), scheduled for partial or total nephrectomy.

Patients, will be recruited in 12-15 renal cancer care specialist centres, who have access to state-of-the-art PET/CT imaging equipment.

The study involves a single administration of 89Zr-TLX250. Imaging will then be conducted 5 +/-2 days post administration. The partial/total nephrectomy will then be performed at institutional discretion any time following the PET/CT imaging visit, but no later than 90 days post administration of 89Zr-TLX250. Histological tumour samples will be prepared and used for histological diagnosis of the renal mass (ccRCC or non-ccRCC) read by a central laboratory.

On Day 5 +/-2 post study drug administration, an abdominal PET/CT imaging will be obtained. In patients, in which unexpected evidence for disseminated disease is observed, PET/CT imaging may be extended to complete whole body imaging(vertex of skull to toe) at the discretion of the investigator.

Image data analyses will be performed by a central image core lab. Qualitative visual analysis (presence or absence of localised 89Zr-TLX250 uptake inside or in vicinity of renal lesion, as seen on contrast-enhanced CT or MRI), will be used to assess test performance or 89Zr-TLX-250 PET/CT imaging to non-invasively detect ccRCC, using histological results from the central histological reference laboratory as standard of truth.
