Filter by:This is a non-blinded phase 2 trial in Stage II-IIIa urothelial cancer randomizing pre-operative nivolumab with or without relatlimab to assess whether bladder preservation after dual immunotherapy would be a viable treatment option for patients responding to treatment
Background: Small cell carcinoma of the bladder (SCCB) and other high-grade neuroendocrine tumors (HGNET) of the urinary tract are rare but aggressive cancers. Average survival for people diagnosed with SCCB or HGNET is about 1 year. Lurbinectedin and avelumab are drugs that are approved to treat other cancers. Researchers want to see if these drugs can help people with SCCB or HGNET. Objective: To test lurbinectedin with or without avelumab in people with SCCB or HGNET. Eligibility: Adults aged 18 years and older with SCBB or HGNET that returned and spread after treatment. Design: Participants will be screened. They will have a physical exam. They will have blood tests and imaging scans. They may need to have a new biopsy: A small needle will be used to collect a tissue sample from the tumor. Both study drugs are given through a tube attached to a needle inserted into a vein. If participants have already received a drug like avelumab they will receive only lurbinectedin. If patients have not been previously treated with a drug like avelumab they will receive both lurbinectedin and avelumab. All participants will receive their treatment once every 3 weeks for up to 10 years. They will also receive other drugs to relieve adverse effects. Biopsies, blood tests, and imaging scans will be repeated during some study visits. Participants may also have urine tests and tests of their heart function. Participants may remain in the study as long as the treatment is helping them. If they stop treatment, they will have safety visits 14, 30, and 90 days after their last dose. Additional follow-up visits will continue 5 to 10 years.
The preoperative evaluation of bladder tumors includes either computed tomography, magnetic resonance imaging in B-mode, or a cystoscopy in the absence of a radiological diagnosis. The diagnosis is confirmed after a transurethral resection of the bladder (TURB) and a histopathological analysis. Ultrasound is a non-invasive imaging technique that uses high-frequency sound waves to produce images of internal structures. Conventional ultrasound in B-mode can only provide details about the tumor's number, size, and location. Elastography uses ultrasound imaging techniques to examine the stiffness of a tissue. Using the Aixplorer system many recently published papers suggested that ShearWave Elasticity (SWE) imaging, enables the differentiation of low- from high-grade breast tumors by assessing the elasticity of the tissue. Investigators intend to evaluate the stiffness of bladder tumors with ultrasound elastography in comparison with cystometry parameters and tumoral grade.
The goal of this clinical trial is to evaluate the protective effect of metformin on nephrotoxicity of cisplatin in patients with bladder cancer. The main questions it aims to answer are: - To determine protective effect of metformin on structural and functional kidney injury caused by cisplatin in patients with bladder cancer. - To evaluate the safety of combining cisplatin and metformin on patients with bladder cancer
The goal of this clinical trial is to compare two treatment regimes, namely, systemic therapy (chemotherapy and/or immunotherapy) alone vs. systemic therapy and radiation therapy in patients with inoperable but localized gallbladder cancer. The main questions it aims to answer are: - Whether adding radiation therapy to systemic therapy improves overall survival? - What are the effects on other endpoints like cancer-free intervals, side effects, and quality of life? Participants will be randomly assigned to one of the two treatment regimes mentioned earlier by a computer-based program. Researchers will compare survival and quality of life outcomes between the two groups.
The purpose of this study is to compare disease free survival (DFS) in participants with recurrence of papillary-only high-risk non-muscle-invasive bladder cancer (HR-NMIBC) within 1 year of last dose of Bacillus Calmette-Guérin (BCG) therapy and who refused or are unfit for Radical Cystectomy (RC), receiving TAR-200 versus investigator's choice of single agent intravesical chemotherapy.
Using a randomized 2 arm design, this study is being conducted to test for non-inferiority of no prophylactic antibiotic therapy versus the prophylactic oral antibiotic, nitrofurantoin, through comparison of rates of postoperative urinary tract infections within the 90-day postoperative period in patients with muscle invasive bladder cancer who undergo radical cystectomy with urinary diversion.
This is an open-label, multicenter phase 1 study to evaluate the safety, efficacy, and pharmacokinetics (PK) characteristics of SIM0237 alone or in combination with bacillus Calmette-Guerin (BCG) in participants with Non-Muscle-Invasive Bladder Cancer (NMIBC)
Currently, the standard of care for female patients undergoing radical cystectomy includes the removal of the bladder, pelvic lymph nodes, anterior vagina, uterus, fallopian tubes and ovaries. Removal of female ancillary organs, both in pre and post-menopausal stages is associated with reduction in various quality of life metrics, including sexual health, cognitive decline and depression. Furthermore, removal of ovaries has been associated with increased cardiovascular events, metabolic acidosis, osteoporosis and bone fractures. In premenopausal women, the removal of the ovaries is associated with increased all-cause mortality. From an oncologic standpoint, multi institutional retrospective reviews have demonstrated certain pre-operative radiographic and cystoscopic risk factors that are associated with bladder cancer involvement of female reproductive organs. The absence of these unfavorable risk factors may provide an opportunity to spare women from undergoing unnecessary reproductive organ removal during RC. In doing so, this may eliminate the associated sequelae of removing these additional organs while also providing acceptable oncologic care. The investigators thus propose a decision tool to stratify women undergoing radical cystectomy as favorable and unfavorable for reproductive organ sparing radical cystectomy. This decision tool classification will be used to decide which patients will undergo reproductive organ sparing radical cystectomy versus radical cystectomy in this study.
This is a first-in-human, multicenter, Phase 1/1b, 3-part, double-blind study of ZH9 in patients with recurrent NMIBC who are eligible for intravesical therapy. In Part 1, the safety, tolerability, and pharmacology of ZH9 IVI will be evaluated in a single ascending dose (SAD) patient cohort. In Part 2, the safety, tolerability, and pharmacology of ZH9 oral prime followed by ZH9 IVI will be evaluated in 2 patient cohorts at the doses and schedule established in Part 1. In Part 3, the safety, pharmacology, and clinical efficacy of ZH9 will be further evaluated in 2 expansion cohorts of patients with recurrent intermediate- and high-risk NMIBC.
