Active clinical trials for "Urinary Bladder Neoplasms"

The aim of this study is to evaluate the outcome of perioperative immune-nutrition with glutamine, arginine and fish oil in patients undergoing radical cystectomy as regards to enhancement of healing, increasing immunity and improving overall health status.

A radical cystectomy + extended pelvic lymph node dissection is considered to be the treatment of choice for patients with muscle invasive bladder cancer (MIBC). Despite this aggressive treatment the outcome is poor and ultimately, 30% of the patients with ≥pT3 tumors develop a pelvic recurrence. One- and 2-years survival for patients developing a local recurrence after cystectomy is only 8% and 3% respectively, with a median survival of <4 months. For patients with lymph node recurrence prognosis is somewhat better, but nevertheless still disappointing with reported 1- and 2 years survival of 42% and 11% respectively. The investigators hypothesize that an earlier implementation of external beam radiotherapy (EBRT) i.e. in the adjuvant setting, will prevent local and lymph node recurrence and improve disease free- and overall survival as local recurrence is linked to the development of distant metastasis. Adjuvant EBRT was tested in a prospective randomized trial and resulted in a 20% increase in 5-year disease free survival. Despite those impressive results, severe intestinal toxicity rates hampered the enthusiasm to use adjuvant EBRT, till now. In the last decade, great technological advancements in EBRT planning, such as intensity modulated arc therapy (IMAT), and positioning have been realised. This has resulted in a better coverage of the target volume while sparing normal tissue (mainly small bowel) and in a more precise delivery of the EBRT. Therefore, it is desirable to reconsider the use of adjuvant EBRT in selected MIBC patients.

This project will conduct a large-sample, multi-center prospective clinical trial to further establish the safety and efficacy of BL-5ALA-PDT in preventing Non-Muscle Invasive Bladder Cancer (NMIBC) recurrence when compared to the usual postoperative perfusion chemotherapy regimen.

Platinum-based chemotherapy remains the standard of care for advanced/metastatic unresectable bladder cancer. The JAVELIN Bladder 100 and HCRN GU14-182 trials showed that maintenance immune checkpoint inhibition(ICI) for those that achieved disease control could prolong progression-free survival (overall survival benefit in JAVELIN may have been related to the lack of guaranteed crossover at time of progression). Of note, both of these studies showed consistency with regards to the magnitude of the PFS benefit which was ~40% vs ~20% at 6-months with maintenance ICI compared to BSC/placebo. Maintenance avelumab is now category 1 on the NCCN guidelines. However, some patients prefer prolonged chemotherapy responses and literature supports a treatment break without effecting longevity. The underlying risk resides in the selection of patients with some (currently difficult to diagnose) progressing rapidly. This trial proposes to use ctDNA to stratify chemo-responsive patients to active surveillance (i.e. a ctDNA responder referred to here as "ctDNA-") vs SOC maintenance pembrolizumab (ctDNA+). All patients will be treated with SOC chemotherapy and only patients with an objective (RECIST) response will be stratified. This is a non-randomized phase 2 study with two arms based on ctDNA Pembrolizumab (ctDNA non-responder) maintenance therapy arm (SOC) Active surveillance arm (ctDNA responders) with serial ctDNA and crossover 1st line chemotherapy is based on physician discretion choice as described in the protocol. Patients with metastatic Urothelial Cancer are enrolled prior to initiation of SOC chemotherapy. Based on ORR (CR + PR), it is estimated that 75 patients will need to enroll onto the protocol to find 25 responders for the two arms.

The goal of this Phase 2 trial is to evaluate a non-surgical bladder-preserving treatment mode which consists of induction chemotherapy plus anti-programmed cell death protein 1 (anti-PD-1) therapy followed by radiotherapy plus concurrent anti-PD-1 therapy. The main questions it aims to answer are: (i) whether the anti-PD-1 antibody, toripalimab, is effective in treating muscle-invasive bladder cancer (MIBC), when combined with chemoradiation; (ii) whether toripalimab is safe in combination with chemoradiation. Participants will receive 3 cycles of induction treatment containing chemotherapy with gemcitabine and cisplatin/carboplatin, plus toripalimab. Then the ones without progressive disease will receive radical radiotherapy plus 2 cycles of concurrent toripalimab.

This study is designed to assess the efficacy and safety of induction therapy with MK-3475 and ASG-22CE and radiation therapy with MK-3475 in patients with cT2-4aN0M0 muscle invasive bladder cancer who are unfit for or refuse radical cystectomy.

The purpose of the present study was to find out the difference in current intensity required for nerve stimulation according to the presence or absence of neuromuscular blockade during the obturator nerve block procedure for TURP.

BCDx is a urine-based multi-omic assay for early cancer recurrence detection in patients with a history of bladder cancer. This prospective, blinded study evaluates its efficacy in detecting recurrent NMIBC, offering a noninvasive monitoring solution.

This single-site, non-randomized, interventional study evaluates the impact of a physical therapy consultation for patients with bladder cancer scheduled for radical cystectomy (RC). The purpose of this study is to investigate whether consultation with a physical therapist and the development of a personally tailored exercise program in the pre-cystectomy period for patients with bladder cancer will result in reduced post-operative complications, morbidity, length of inpatient stay, improve readmission 30-day and 90-day and improve 90-day mortality. This study will be partially retrospective (pre-implementation of a physical therapy consultation order) and partially prospective.

The primary objective of this study, sponsored by Travera Inc. in Massachusetts, is to validate whether the mass response biomarker has potential to predict response of patients to specific therapies or therapeutic combinations using isolated tumor cells from various specimen formats including malignant fluids such as pleural effusions and ascites, core needle biopsies, fine needle aspirates, or resections.
