Carcinoma, Transitional Cell clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

NCT ID: NCT00867620 Enrolling by invitation - Bladder Cancer Clinical Trials

Development of a Non-Invasive DNA Methylation-Based Assay System for the Risk Assessment of Urothelial Carcinoma

Start date: August 2008
Phase: N/A
Study type: Observational

Bladder cancer ranks the ninth in worldwide cancer incidence. Approximate 90% of bladder cancer is the malignancy of urothelium tissues, the urothelial cancer (UC). The mortality of bladder cancer is mainly due to recurrence and metastasis. Unfortunately, the currently available cytology or cystoscopy examination is of limited value because of low sensitivity of early disease. New biomarkers as well as detection technology are thus required to improve early diagnosis. By the aid of quantitative methylation-specific PCR (QMSP), which allows detecting tumor-derived DNA from tissues and body fluids, DNA methylation-based assay is thus developing for early detection and prognosis. The goal of this proposed project is to develop a panel of DNA-methylation based biomarkers for UC diagnosis, prognosis, and prediction of responses to therapy (especially the recurrence, invasion, survival, and responses to therapeutic agents). Although numerous studies have investigated the aberrant promoter hypermethylation in bladder cancers or UC, inconsistent results are observed. DNA hypermethylation determination may rely on not only the conditions of QMSP, but also the biopsy specimens of different race, environmental expose factors, and regional variation. We thus need to profile the DNA methylation pattern of UC patients in Taiwan to establish a panel of potential prediction biomarkers for local patients.
