Active clinical trials for "Urinary Bladder Neoplasms"

This is a phase II, multicenter, randomized open-label and comparative study designed to evaluate whether local consolidative radiotherapy plus standard of care improves overall survival as compared to standard of care in patients with limited metastatic urothelial bladder cancer and without progression following the initial phase of first-line systemic therapy. Each patient will be followed during 4 years from the date of randomization.

The purpose of this study is to examine the usefulness of implanting small 24-K gold fiducial markers around a bladder tumor site, so that a Radiation Oncologist can identify the original tumor location at the time of radiation treatment. Other goals of the study include assessing whether a new MRI imaging technology can help with detection of bladder cancer earlier and more accurately when evidence of bladder cancer is not visible by scope.

This research study is examining the effectiveness of pembrolizumab plus cryoablation on people with urothelial carcinoma, including bladder cancer, that has spread.

The purpose of this study is to assess the effectiveness of erdafitinib in people with non-muscle invasive bladder cancer (NMIBC) that has come back after standard treatment, such as Bacillus Calmette-Guerin (BCG) or chemotherapy instilled into the bladder. Participants in this study will have bladder cancer with a mutation in the FGFR3 gene. FGFR3 mutations are the most common genetic alteration in NMIBC and is present in the majority of recurrent NMIBC tumors. Genetic testing of the participant's prior or recurrent NMIBC tumor will be performed to confirm it has an FGFR3 gene mutation. Erdafitinib is a pill given orally (by mouth) that blocks the protein made by this altered gene, which may stop cancer cells from growing. Erdafitinib is already used as an approved treatment for metastatic bladder cancer. Researchers are doing this study to determine whether erdafitinib is an effective treatment for FGFR3-altered non-muscle invasive bladder cancer in the time period between when a recurrent tumor is identified and a TURBT (transurethral resection of a bladder tumor) or biopsy procedure is performed to remove it.

Few previous studies focused on the neoadjuvant treatments of upper urinary or bladder cancer, especially chemotherapy combined with immunotherapy, however, available data of retrospective studies showed this neoadjuvant treatment model might benefit patients. So This prospective Phase II clinical trial was designed to explore the efficacy of chemotherapy combined with PD-1 inhibitor as neoadjuvant therapy in upper urinary and muscle-invasive bladder urothelial carcinoma, then to improve the rate of complete pathological remission, survival and provide medical evidence.

This phase II trial studies the effect of adding pembrolizumab to gemcitabine in treating patients with non-muscle invasive bladder cancer whose cancer does not respond to Bacillus Calmette-Guerin (BCG) treatment. Chemotherapy drugs, such as gemcitabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the patient's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Adding pembrolizumab to gemcitabine may delay the return of BCG-unresponsive bladder cancer for longer period compared to gemcitabine alone.

The goal of this clinical trial is to evaluate the efficacy and safety of Cadonilimab(AK104) combined with Nab -Paclitaxel as first line therapy for recurrent or metastatic muscle invasive bladder. Eligible participants will receive AK104 (up to 24 months) plus Nab-Paclitaxel (for 6 cycles) until radiologic disease progression, unacceptable toxicity, or withdrawal from the study, whichever occurred first. The primary endpoint is objective response rate.

This is a multi-center, stratified and single-blinded Phase 2 study of neoadjuvant immunotherapy in combination with the antiGDF15 antibody visugromab (CTL-002) for the treatment of subjects with MIBC set to undergo radical Cystectomy (RC) who cannot receive or refuse to receive cisplatin-based chemotherapy.

This phase I trial tests the safety and side effects of a PD-L1/IDO peptide vaccine (IO102-IO103) in combination with pembrolizumab in treating patients with non-muscle invasive bladder cancer. IO102-IO103 is a novel IDO and PD-L1 peptide based immune-modulatory therapeutic. It is designed to activate the patient's own immune cells (called T-cells) to fight the tumor and stop the tumor cells escaping from the body's immune system. IO102-IO103 works to directly kill tumor cells and remove the body's immune suppressive cells, which are cells that prevent the immune system from fighting the tumor. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving IO102-IO103 in combination with pembrolizumab may make tumor cells more visible/recognizable to the immune system.

This is a prospective, open, single-center clinical study of anti-HER2-ADC combined with PD-1 monoclonal antibody for bladder sparing treatment in non-muscular invasive bladder cancer (NMIBC) patients with HER2-expressing. The study was conducted in accordance with the Good Clinical Practice (GCP). Approximately 20 subjects will be enrolled to evaluate the efficacy and safety of RC48 (RC48 2.0 mg/kg intravenously administered every two weeks) combined with Tislelizumab (Tislelizumab 200 mg intravenously administered every three weeks). Subjects undergo Transurethral resection of bladder tumor (TURBT), imaging diagnosis and pre-treatment biological samples of blood, urine and biopsy tissue. The study will include high-risk NMIBC patients who express HER2, fail after BCG treatment, but refuse to undergo cystectomy or do not meet the requirements for cystectomy. Subjects will receive RC48 and Tislelizumab for two years. BI-DFS were evaluated by cystoscopy, histopathologic examination, laboratory examination, and imaging examination after treatment, and tumor efficacy was evaluated when clinical studies reached the number of subjects specified in the protocol for efficacy evaluation.
