Filter by:The Primary Objective of this observational study is to investigate the prevalence of high PD-L1 expression in Chinese MIUBC patients.
This study is being done test to test the safety and effectiveness of durvalumab combined with tremelimumab in patients who have a rare form of cancer of the urinary tract.
Is BladderLight® (BL) urine testing accurate, as a non-invasive method, to exclude presence of bladder cancer in patients.
Bladder cancer is the fourth and eighth most common malignancy among men and women, respectively. About 75% of bladder cancers are diagnosed as non muscle-invasive and according to specific tumor-stage and grade characteristics, intravesical immunotherapy with Bacillus Calmette-Guérin (BCG) is used to prevent recurrence and/or progression. However, BCG immunotherapy is associated with significant adverse events and treatment failure may occur in 30-40% of cases, hence the necessity for alternative therapies. In an orthotopic MB49 mouse bladder cancer model, another bacterial vaccine (Ty21a/Vivotif) turned out to be more effective than BCG for inducing tumor regression and mice survival upon intravesical instillation; and potentially safer because Ty21a bacteria did not infect/persist in any mice tissues nor in human bladder explants or cell lines, in contrast to BCG. Ty21a/Vivotif has been used in the last 30 years in millions of individuals as an oral typhoid vaccine with a high safety record. In this phase I trial we will be testing the safety of intravesical administration of Ty21a and its effect on bladder immunity in non-muscle invasive bladder cancer (NMIBC) patients, for whom recommendation of BCG therapy is not mandatory.
This randomized phase II trial studies how well radiation therapy and pembrolizumab work in treating patients with urothelial bladder cancer that is restricted to the site of origin, without evidence of spread. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Monoclonal antibodies, such as pembrolizumab, may interfere with the ability of tumor cells to grow and spread. Giving radiation therapy and pembrolizumab may work better in treating urothelial bladder cancer.
The purpose of this study is to create a registry, which is a "bank" of information about patients who have had similar medical conditions and treatments. The registry will be used by researchers to learn more about long term outcome of patients with bladder cancer, how bladder cancer tissues are related to tumor development, recurrence and survival.
The standard non-surgical treatment for muscle invasive bladder cancer is concurrent chemo-radiotherapy. This treatment is associated with long term side effects in around a third of patients with up to 12% suffering from grade 3-4 toxicity. Effective radiotherapy depends on delivering a curative dose to the target whilst minimising dose to surrounding tissues to reduce toxicities. As an organ that constantly varies in shape and position, achieving this in bladder irradiation is challenging. Cone beam Computed Tomography (CBCT) has allowed visualisation of soft tissue on treatment and hence image-guided treatment and improved accuracy, but the image quality of CBCT is suboptimal for distinguishing soft tissue boundaries. On the other hand, MRI scans produce superior soft tissue definition and visualisation of tumour bed. This would in turn allow for various ways of optimising treatment and potentially improving outcome. There have been a number of studies evaluating pelvic organ motion in bladder cancer as well as assessing different adaptive radiotherapy strategies. These have included individualized margins, plan of the day and adaptive techniques. Most of these studies have been carried out using CBCT imaging which is often poor quality with limited soft tissue contrast. MRI offers better visualization of the tumour bed and organs at risk (OARs). As a result, the utilisation of MRI in radiotherapy could allow for increased radiation dose to the tumour bed while maintaining minimal dose to surrounding soft tissue. This study will explore the role of MRI imaging in adaptive radiotherapy for bladder cancer with development of a number of theoretical treatment strategies.
The purpose of this study is to evaluate both the safety and tolerability of up to 4 dosing cycles of TAR-200 for 21 days per dosing cycle in the induction period.
The purpose of the ATLAS study is to determine how patients with locally advanced unresectable or metastatic urothelial carcinoma respond to treatment with rucaparib.
The purpose of the present study is to compare the effect of PEEP on arterial oxygen partial pressure in elderly patients undergoing urologic surgery using LMA supreme™ in a lithotomy position.
