Clinical Evaluation of 18F-LN1 PET/CT for Imaging of Nectin-4 in Urothelial Carcinomas

The clinical feasibility of 18F-LN1 PET/CT will be evaluated in 30 patients with urothelial carcinoma, and the results will be compared with those of 18F-FDG.


PET Biodistribution Study of 68Ga-FAPI-46 in Patients With Different Malignancies: An Exploratory Biodistribution Study With Histopathology Validation

This exploratory study investigates how an imaging technique called 68Ga-FAPi-46 PET/CT can determine where and to which degree the FAPI tracer (68Ga-FAPi-46) accumulates in normal and cancer tissues in patients with cancer. Because some cancers take up 68Ga-FAPi-46 it can be seen with PET. FAP stands for Fibroblast Activation Protein. FAP is produced by cells that surround tumors (cancer associated fibroblasts). The function of FAP is not well understood but imaging studies have shown that FAP can be detected with FAPI PET/CT. Imaging FAP with FAPI PET/CT may in the future provide additional information about various cancers.


Evaluating the Impact of 18F-FDG-PET-CT on Risk Stratification and Treatment Adaptation for Patients With Muscle Invasive Bladder Cancer (EFFORT-MIBC): A Phase II Prospective Trial

Evaluate the impact of 18F-FDG-PET-CT on the staging of patients with muscle invasive bladder cancer. Based on the results of 2 18F-FDG-PET-CT's patients are stratified in non-metastatic, oligometastatic and polymetastatic bladder cancer patients and the treatment is adapted accordingly to improve overall survival.


A First-in-Human, Phase I/II PET Imaging Study of 64Cu-GRIP B, a Radiotracer Targeting Granzyme B, in Patients With Advanced Genitourinary Malignancies

This is a first-in-human phase I/II imaging study of 64Cu-GRIP B PET in patients with advanced genitourinary (GU) malignancies. The tracer is designed to detect extracellular granzyme B as it is secreted by activated immune cells in the tumor microenvironment, which may highlight tumors that will regress on treatment with immunomodulatory therapies. The study population is focused on genitourinary malignancies, including renal cell and urothelial cancer, two tumor types with high mutational burden and tumor infiltrating lymphocytes compared to other tumor types, and have a predictable response rate at the population level to immune checkpoint inhibitors.


Exploratory Study on the Effectiveness of Gallium [68Ga] NOTA-SGC8 Injection in the Staging of Bladder Cancer

Brief Summary: The goal of this clinical trial is to test the imaging and diagnostic ability of [68Ga]-NOTA-SGC8 PET/MR in bladder cancer patients with different stages. The main questions it aims to answer are: Tumor specific lighting ability of [68Ga]-NOTA-SGC8 in bladder cancer patients with different stages. The safety of [68Ga]-NOTA-SGC8. Participants will be irrigated with [68Ga]-NOTA-SGC8 into the bladder for tumor imaging under PET/MR. The imaging performance of [68Ga]-NOTA-SGC8 on different stages of bladder tumors will be systematically evaluated by combining with pathological sections of patients. Urine accumulation and radioactivity distribution of [68Ga]-NOTA-SGC8 will be measured. The adverse events will be recorded.
