Active clinical trials for "Urinary Bladder Neoplasms"

This study is aimed to determine whether low- and standard-pressure pneumoperitoneum have different impacts on troponin T（TnT) level as well as pulmonary complications after prolonged robot-assisted surgeries in the Trendelenburg position.

Aim and objectives: This trial aims to evaluate the role of adjuvant radiotherapy following chemotherapy in patients with high-risk features on histo-pathology after radical surgery for transitional cell carcinoma of urinary bladder

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.

Obturator nerve block is an effective method to prevent adductor muscles contraction during transurethral resection of bladder tumour localized on the lateral wall. Due to prior spinal anaesthesia the patient does not feel uncomfortable during the blockade and the interadductor approach gives the possibility to perform it in the lithotomy position. The aim of the study was to evaluate the safety and effectiveness of ultrasound-guided obturator nerve identification and blockade for TURBT.

This is a Phase I/II and multicenter study designed to evaluate the efficacy and safety of 4SCAR-T cells in participants with locally advanced or metastatic urothelial bladder cancer (UBC) who have no further treatment available.

Compare the therapeutic utility of SPIES assisted TURB with WLI assisted TURB in patients with non-muscle invasive bladder cancer.

RATIONALE: Sunitinib malate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. PURPOSE: This phase II trial is studying the side effects of giving sunitinib malate and to see how well it works in treating patients with locally recurrent, locally advanced, unresectable, or metastatic urinary tract cancer.

This is a single centre, open label, phase I dose escalation trial using a modified accelerated titration design. Patients with superficial bladder tumour (Ta or T1) or CIS and candidates for transurethral resection or muscle invasive disease (>T2) and candidates for radical cystectomy will be enrolled. OGX-427 will be given neoadjuvantly over 8 days, followed by a transurethral resection (for superficial disease) or radical cystectomy (for muscle invasive disease). Baseline Hsp27 levels will be determined from pre-treatment cytological samples from bladder washings and tumour biopsies performed prior to therapy. Post-treatment PK and PD data will be determined from TUR (for Ta, T1 tumours) or radical cystectomy (for T2 tumours) specimens. A recommended phase II dose will be determined from the toxicity, tissue pK, and percentage of Hsp27 knockdown. Effects of treatment on Hsp27 client protein levels and apoptotic index will also be evaluated. Evaluation during protocol treatment will take place to assess toxicity. Assessments will occur on various visits as per Evaluation Schedule. Adverse event evaluation based on NCI CTCAEv3.0. For quality of life assessment during treatment, the EORTC QLC-BLS24 will be used before first treatment (day 1) and prior to surgery (TURBT or radical cystectomy). The Day 1 QOL assessment will serve as baseline. After removal from protocol treatment, all subjects will be followed for toxicity related to study drug for 30 days. After the study, subjects will be followed according to standard of care. Follow-up for tumour recurrence or superficial tumours will be assessed every three months by cystoscopic examination for two years, then every six months for the next two years, and then yearly thereafter.

RATIONALE: Hyperthermia therapy kills tumor cells by heating them to several degrees above normal body temperature. Drugs used in chemotherapy, such as mitomycin C and epirubicin hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Biological therapies, such as bacillus calmette-guerin (BCG) and interferon alfa, may stimulate the immune system in different ways and stop tumor cells from growing. It is not yet known whether giving hyperthermia together with mitomycin C is more effective than giving BCG or standard therapy as second-line therapy in treating patients with recurrent bladder cancer. PURPOSE: This randomized phase III trial is studying how well hyperthermia given together with mitomycin C works compared with BCG or standard therapy as second-line therapy in treating patients with recurrent bladder cancer.

Primary Objective: To analyse time to tumor progression in patients cystectomized for locally advanced transitional cell carcinoma (TCC) of the bladder, who are not suitable for cisplatin-based chemotherapy (i.e. postoperative reduced renal function, advanced age). Patients are randomized to receive either adjuvant gemcitabine immediately after radical operation (treatment arm A) or no treatment (control arm B). Patients in the control arm are to be treated with gemcitabine as soon as tumor progression becomes evident clinically and/or radiologically. Secondary Objectives: The secondary objectives of this study are: Estimation of time-specific survival probabilities irrespective of causes of death. Assessment of toxicity and tolerability of gemcitabine Description of survival experience of patients in the control arm beyond the time of initiating chemotherapy. Assessment of quality of life (European Organization for Research and Treatment of Cancer [EORTC] Quality of Life Questionnaire [QLQ]-C30). Study Design: This is an open-label, prospective, multicenter, randomized, controlled phase 3 two-arm study using gemcitabine as a single agent in chemonaive cystectomy patients with locally advanced TCC of the bladder in an adjuvant setting. The patients will receive the following treatment: Arm A (treatment): gemcitabine 1250 mg/m2 intravenously once a week for 2 weeks (days 1 and 8) followed by 1-week rest period. Repeat cycle on day 22. Maximum of 6 cycles. Begin treatment until 3 months after radical operation (within first 6 weeks is recommended). Arm B (control): No immediate post-surgery treatment. Watchful waiting; treatment only conditionally in case of progression with gemcitabine (dose and schedule as in arm A).
