Outcome Measures

Primary Outcome Measures

Qualitative assessment of 89Zr-girentuximab uptake within individual tumor deposits [Single diagnostic administration, followed by a diagnostic scan on Day 5 ± 2 days. This assessment will be conducted throughout the patient dosing and imaging period, an average of 18 months]
This outcome will be evaluated on all patients by using a PET/CT machine to qualitatively assess (yes / no) the uptake of the 89Zr-girentuximab uptake within individual tumor deposits.
Quantitative assessment of 89Zr-girentuximab uptake within individual tumor deposits [Single diagnostic administration, followed by a diagnostic scan on Day 5 ± 2 days. This assessment will be conducted throughout the patient dosing and imaging period, an average of 18 months]
This outcome will be evaluated on all patients by using a PET/CT machine to quantitatively assess the uptake of the 89Zr-girentuximab uptake within individual tumor deposits.

Secondary Outcome Measures

To evaluate safety parameter of Heart rate in patients administered with 89Zr-girentuximab [Patients will be evaluated for the period up to imaging following administration of 89Zr-girentuximab, at most 7 days.]
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 period up to imaging following administration of 89Zr-girentuximab, up to 7 days.]
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 safety parameter related to Liver function in patients administered 89Zr-girentuximab [Patients will be evaluated for the period up to imaging following administration of 89Zr-girentuximab, up to 7 days.]
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 period up to imaging following administration of 89Zr-girentuximab, up to 7 days.]
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 period up to imaging following administration of 89Zr-girentuximab, up to 7 days.]
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.
