Personalized Urine Biomarker for Patients With Bladder Cancer

Start date: August 2022
Phase:
Study type: Observational

Introduction Bladder cancer is the most common malignancy involving the urinary system and the ninth most common malignancy worldwide. Urothelial carcinoma is accounts for approximately 90 percent of bladder cancers in the western world. In the United States, approximately 80,000 new cases and 17,000 deaths occur each year due to bladder cancer. Approximately 75% of patients present with superficial disease (Ta and T1), while 25% present with muscle invasive (T2 or greater) disease. Overall, 70% of treated tumors recur, with 30% of recurrent tumors progressing to muscle invasive disease. The majority of these patients have a recurrence after endoscopic resection, thus lifelong surveillance with periodically cystoscopy is recommended. Cystoscopy, which is the "gold standard" for the detection of bladder cancer, is an expensive and invasive procedure, and it also can miss a flat lesion, especially carcinoma in situ which is considered a high grade malignant condition, therefore better follow-up tools should be developed in order to address those issues. Voided urinary cytology is a useful noninvasive adjunct to cystoscopy due to its high specificity, more than 90%. Although it has a high sensitivity at detecting high-grade lesions, between 80 to 90%,, in low-grade its sensitivity is very low, between 20 to 50%. Amongst the non-muscle-invasive, low grade tumors will progress to muscle-invasive or metastatic cancer at approximately 10% and roughly a third of high-grade tumors progress, therefore, close monitoring and early detection of all lesions are important for management, and noninvasive tumor markers with high accuracy for the detection of all grades of urothelial carcinoma will significantly reduce patient cost, anxiety and morbidity. Cystoscopy in combination with cytology remains the most effective means of detecting bladder cancer. However, cystoscopy is an invasive procedure, and while cytology remains a useful method for detecting high grade tumors, its utility in detecting low grade tumors remains limited due to the lack of distinguishing cytological features between low grade disease and reactive processes. Currently there are several markers available or under investigation for the detection and monitoring/surveillance of bladder cancer, most of them have higher sensitivities, especially when used to identify low grade disease, but with lower specificities when compared to cytology. Furthermore, all of these tests must still be utilized in conjunction with cystoscopy findings. Recently, cell-free DNA (cfDNA) isolated from urine supernatant has been shown to have great potential in bladder cancer detection and surveillance. Bladder cancer exhibits unique genetic features that can be identified from sequencing and expression of cfDNA. Aim of study: The aim of this study is to establish a method for a personalized urinary biomarker with the usage of well explored urothelail cancer genetic mutations in urine cfDNA, for the detection of bladder cancer presence.

Smurf2 Gene Expression in Urinary Tract Tumors

Start date: December 2021
Phase:
Study type: Observational

Smurf2 and bladder cancer - research proposal summary The Smurf2 gene was recently identified as a tumor suppressor gene. It is an E3 ubiquitin ligase and carries a significant role in major cellular processes such as cell division, genomic stability, DNA repair as well as resistance to anti-tumoral drugs. Recent studies showed that in several common tumors (prostate, breast, osteosarcoma etc.), a significant decrease in the expression or activity of Smurf2 can be noted, making the cells more susceptible to malignant transformation and the tumors more aggressive and highly resistant to various medications. Bladder cancer is no. 4 cancer in men and 6 in women, and a major cause of cancer related death. Common risk factors are smoking and occupational exposure to aniline dyes or aromatic amines. Its' most common presentation is painless hematuria. Once the diagnosis of a bladder tumor is made, endoscopic resection of the tumors is performed. Superficial tumors of low malignancy may be treated by repeated resections, highly malignant tumors require additional therapy and aggressive tumors invading the bladder muscle layer require radical surgery and chemo-radiotherapy. Therefore, all patients are closely monitored by repeated cystoscopies (endoscopic inspection of the bladder), each 3 months, lifelong. In an effort to minimize patients' discomfort, there is a constant search for a reliable biomarker in the urine of patients. A marker with good sensitivity and specificity will predict in a noninvasive fashion early recurrence or absence of bladder tumors, sparing the need for invasive cystoscopy. The presence of a biomarker may be used as prognostic factor or a measure of response to therapy. The aim of this research is to characterize the presence of smurf2 in bladder tumors and determine whether it may be utilized as a reliable biomarker for bladder cancer.

Preventing Catheter Related Bladder Discomfort (CRBD) With Bilateral Pudendal Nerve Block

Start date: August 10, 2021
Phase: Early Phase 1
Study type: Interventional

Bladder irrigation with a 3 way foley catheter is an important component of post operative management of transurethral bladder surgeries. But it is associated with a high incidence of bladder discomfort. Catheter related bladder discomfort (CRBD) doesn't respond to the orthodox opioid pain medication and is greatly distressful to the patients postoperatively, adversely affecting the quality of recovery often requiring administration of additional pain medication thereby increasing treatment costs, patient dissatisfaction and longer hospital stays. Several systemic agents have been used to reduce CRBD, but they have many side effects. A trial has been planned to find a way of reducing CRBD avoid distressing systemic side effects

Bipolar Versus Mono-polar Needlescopic En Bloc TUR-BT

Start date: November 1, 2019
Phase: N/A
Study type: Interventional

NCT ID: NCT04784507 Recruiting - Bladder Neoplasm Clinical Trials

En-Bloc Resection of Bladder Tumors

Start date: April 1, 2020
Phase: Phase 2
Study type: Interventional

Observational data shows that "en bloc" resection of bladder tumor (EBR-BT) may entail advantages when compared with conventional transurethral bladder tumor resection (TURBT). EBR-BT has the potential to increase the rate of correct staging and accurate assignment of risk-classification in non-muscle-invasive bladder cancer (NMIBC) and to avoid re-TURBT in a considerable number of high-grade NMIBC by demonstrating total macro and microscopic eradication of the primary tumor and to provide the basis for a correct treatment based on a correct stage. Following the rules of the IDEAL collaboration evaluation and stages of surgical innovation and considering EBR-BT as a surgical technical innovation, the investigators designed a multi-institutional, stage 2a/b study on feasibility (procedural success), safety (including pathology features), and short-term efficacy of EBR-BT and as proof of concept on the reliability of NMIBC staging. Main objective: to prospectively assess the pathological efficacy of EBR-BT in the staging of bladder cancer and the clinical efficacy at short-term recurrence-free survival. Secondary objectives: To assess the clinical efficacy at short-term (3-months) of EBR-BT, and to compare efficacy in the staging of the EBR-BT with the conventional TURBT.

Phase: Phase 1
Study type: Interventional

This study will be conducted in adult subjects diagnosed with any form of an advanced or metastatic solid tumors including urothelial carcinoma for which standard therapy is no longer effective or is intolerable. This is a phase 1, multi-center, open label study designed to assess safety and tolerability of IK-175 as a single agent and in combination with nivolumab, to determine the recommended phase 2 dose (RP2D). Disease response, pharmacokinetics (PK), pharmacodynamics, and response biomarkers will also be assessed.
