Phase 3 |
Detailed Description
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.

Outcome Measures
Primary Outcome Measures
- To evaluate sensitivity and specificity of PET/CT imaging with 89Zr-TLX250 to non-invasively detect ccRCC in patients with indeterminate renal masses, using histology as standard of truth [Single diagnostic administration, followed by a diagnostic scan on Day 5 ± 2 days. Histological confirmation from nephrectomy material will serve as standard of truth.]
This outcome will be evaluated on all patients by using a PET/CT machine to determine the uptake of the Zr89 radiotracer within the renal lesion. This will be compared against the histological determination of the lesion type following resection of the lesion
Secondary Outcome Measures
- To evaluate sensitivity and specificity of 89Zr-girentuximab PET/CT imaging to detect ccRCC in the subgroup of patients with indeterminate renal masses of ≤ 2cm in largest diameter using histology as standard of truth [Single diagnostic administration, followed by a diagnostic scan on Day 5 ± 2 days. Resection to be conducted within 90 days of administration of 89Zr-girentuximab.]
This outcome will be evaluated on all patients with a lesion ≤ 2cm in largest diameter by using a PET/CT machine to determine the uptake of the Zr89 radiotracer within the renal lesion. This amount of uptake in the lesion will be compared with the histologically determined cancer type following resection of the lesion
- To evaluate positive predictive value (PPV), and accuracy of 89Zr-girentuximab PET/CT imaging to detect ccRCC in patients with indeterminate solid renal masses [This analysis will be conducted after all patients have completed study involvement]
This outcome will be determining the proportion (as a percent) of the whole study population in which the PET/CT imaging could correctly predict if an individual patient had clear cell renal cell carcinoma or can correctly predict if the patient did not have clear cell renal cell carcinoma
- To define a standardized uptake value (SUV) cut-off for 89Zr-girentuximab, suitable to discriminate ccRCC from non-ccRCC [Single diagnostic administration, followed by a diagnostic scan on Day 5 ± 2 days. Resection to be conducted within 90 days of administration of 89Zr-girentuximab]
This outcome will be conducted on the whole study population and will use the counts derived from the PET/CT imaging of the 89Zr in the target tissue in order to see if there is a mathematical way to derive the tumour type information from the imaging alone. The tumour type will be determined by the histological sample obtained following resection.
- To evaluate the correlation between 89Zr- girentuximab SUVs and degree of histological carbonic anhydrase IX (CAIX) expression [Single diagnostic administration, followed by a diagnostic scan on Day 5 ± 2 days. Resection to be conducted within 90 days of administration of 89Zr-girentuximab]
This outcome will be assessed on all patients. The counts derived from the PET/CT imaging of the renal lesion will be compared with the amount of CAIX expressed in the histologically extracted sample
- To evaluate inter-reader variability of diagnostic assessments of 89Zr- girentuximab PET/CT images, when performed by multiple readers [This analysis will be conducted through study completion, on average of 5 months]
This outcome will be conducted on all patients. Three blinded readers operating independently will be used to read each patient PET/CT image and determine if the target lesion is positive for Zr89. A comparison of findings will then be made between the readers for each patient individually.
- To evaluate intra-reader variability of diagnostic assessments of 89Zr- girentuximab PET/CT images [This analysis will be conducted through study completion, on average of 5 months]
This outcome will be conducted on a randomly determined subset of 10% of the patients. Three readers blinded to the histological outcome will be asked to read each patient PET/CT image on two occasions and determine if the target lesion is positive for Zr89. The results will be evaluated as a percent figure to consistently report the same finding with each patient.
- To evaluate safety parameter of Heart rate in patients administered with 89Zr-girentuximab. [Patients will be evaluated for the 90 day period following administration of 89Zr-girentuximab]
This outcome will be measured as beats per minute on all patients with treatment-related adverse events based on criteria as determined by the NCI CTCAE v 5.0 criteria
- To evaluate safety parameter of blood pressure in patients administered with 89Zr-girentuximab. [Patients will be evaluated for the 90 day period following administration of 89Zr-girentuximab]
This outcome will be measured as mmHg on all patients with treatment-related adverse events based on criteria as determined by the NCI CTCAE v 5.0 criteria
- To evaluate negative predictive value (NPV) and accuracy of 89Zr-girentuximab PET/CT imaging to detect ccRCC in patients with indeterminate solid renal masses [This analysis will be conducted through study completion, on average 5 months]
This outcome will be determining the proportion (as a percent) of the whole study population in which the PET/CT imaging could correctly predict if an individual patient had clear cell renal cell carcinoma or can correctly predict if the patient did not have clear cell renal cell carcinoma
- To evaluate safety parameter related to Liver function in patients administered 89Zr-girentuximab [Patients will be evaluated for the 90 day period following administration of 89Zr-girentuximab]
This outcome will be measured on all patients with treatment-related adverse events based on criteria as determined by the NCI CTCAE v 5.0 criteria. Results will be assessed by number of participants with abnormal laboratory values.
- To evaluate safety parameter related to Renal function in patients administered 89Zr-girentuximab [Patients will be evaluated for the 90 day period following administration of 89Zr-girentuximab]
This outcome will be measured on all patients with treatment-related adverse events based on criteria as determined by the NCI CTCAE v 5.0 criteria. Results will be assessed by number of participants with abnormal laboratory values.
- To evaluate safety parameter related to Full Blood Count in patients administered 89Zr-girentuximab [Patients will be evaluated for the 90 day period following administration of 89Zr-girentuximab]
This outcome will be measured on all patients with treatment-related adverse events based on criteria as determined by the NCI CTCAE v 5.0 criteria. Results will be assessed by number of participants with abnormal laboratory values.
Other Outcome Measures
- To quantitatively estimate achievable radiation absorbed doses (Gy) for therapeutic 177 Lutetium-girentuximab based on single time point 89Zr-girentuximab PET/CT images [This analysis will be conducted after all patients have completed study involvement, an average of 1 year]
This outcome will be assessed by determining the radiation absorbed dose, using Monte Carlo analysis, that would have been delivered to the target tissue had the girentuximab been bound alternatively with the therapeutic radionuclide 177Lu, rather than the diagnostic 89Zr label.
