The Efficacy of Gallium[68Ga]NOTA-DNA Multivalent SGC8 Injection for Bladder Tumour Imaging

Condition(s) studied

Investigational drug(s) / intervention(s)

Gallium[68Ga]NOTA-DNA Multivalent SGC8 Injection: On the examination bed, the patient was placed in the lying truncated position, the perineum was disinfected with a towel, and a double-lumen urinary catheter was inserted via the perineum.Inject 50ml saline to clean the bladder once, open the drainage bag to drain.1mci SGC8 was dissolved in 50ml physiological saline. The drainage bag was clamped shut and 50ml of developer was injected into the bladder through the catheter, followed by 10ml of gas or saline (all developer in the ureter was injected into the bladder. The catheter was closed for 1 hour, during which time the patient was placed in the flat position, left lateral position, right lateral position, and supine position changing positions every 15 minutes.After 1 hour, the drainage bag was opened, the bladder was emptied with radioactive fluid, and the urine bag was replaced.

Study summary

The study was planned to include patients with bladder tumors attending the Department of Urology, Renji Hospital, Shanghai Jiaotong University School of Medicine, from 09/2024 to 12/2025. Patient demographics will be collected, patients will be monitored for medical history and co-morbidities, co-morbid medications or treatments, vital signs, and cystoscopy will be performed. Patients meeting the inclusion criteria will be included in this study. Patients will receive PET/MR imaging after bladder instillation of \[68Ga\] NOTA-DNA multivalent SGC8 injection to assess the effectiveness of bladder tumor imaging and to evaluate the safety of \[68Ga\] NOTA-DNA multivalent SGC8.

The primary study was the ability of gallium \[68Ga\] NOTA-DNA multivalent SGC8 injection to provide tumor-specific imaging of bladder tumor patients of different genders, with a compliance rate of more than 80% when compared to the gold standard TUR pathology. To study the safety of gallium\[68Ga\] NOTA-DNA multivalent SGC8 injection; to assess the correlation between gallium\[68Ga\] NOTA-DNA multivalent SGC8 imaging ability and clinical parameters; to study the ability of gallium \[68Ga\]NOTA-DNA multivalent SGC8 to differentiate between bladder tumor foci and inflammatory foci; to explore the gallium \[68Ga\]NOTA- DNA multivalent SGC8 target PTK7 receptor protein expression in bladder tumors and the correlation between tumor differentiation and malignancy.
