Brief summary
The aim of this study is to determine if it is practical to use 89Zr-TLX250 PET/CT in the staging and detection of localized and metastatic urothelial carcinoma or bladder cancer. The primary objective is to evaluate the feasibility of using 89Zr-TLX250 PET/CTas a new diagnostic and staging modality to detect urothelial carcinoma or bladder cancer.
Detailed description
This will be a non-randomised, non-blinded, single centre, phase 1 feasibility study comparing 89Zr-girentuximab PET with FDG PET in patients with urothelial carcinoma or bladder cancer. This study would include 2 cohorts of adult patients; those with known metastatic urothelial carcinoma and bladder cancer and those undergoing primary staging for recently diagnosed urothelial carcinoma or bladder cancer. This study is open-label, single centre and eligible patients will receive a single administration of study drug prior to imaging on day 5 (+/- 2 days). PET scans will be independently interpreted by nuclear medicine physicians blinded to the FDG PET findings. For patients proceeding to radical cystectomy, subsequent histological confirmation of areas of increased uptake will be retrospectively correlated with both PET scans.
Interventions
Administration of 89Zr-girentuximab as per protocol.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Comparison of the sensitivity and specificity of 89Zr-girentuximab PET with FDG PET | Day 1 - Day 90 | Sensitivity and specificity will be established following histological confirmation |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| To evaluate the correlation between 89Zr-girentuximab SUV's and degree of urinary carbonic anhydrase IX excretion (cytology and CA-IX via PCR). | Day 1 | 89Zr-girentuximab SUV's will be correlated with urinary CA-IX expression |
| Number of participants with treatment related adverse events related to 89Zr-girentuximab administration | Day 1 to Day 90 | Number of participants with treatment-related adverse events as assessed by NCI-CTCAE v 5.0 criteria |
| To quantify the correlation between tumour volume using MIM quantitative software and histopathological findings | Day 1 - Day 90 | Tumour burden as defined by volumetric software will be correlated with histopathological results |
