BladMetrix Urine Test for Monitoring Recurrence in Non-Muscle Invasive Bladder Cancer

This observational study evaluates the urine test BladMetrix for monitoring bladder cancer recurrences in people with non muscle invasive bladder cancer (NMIBC) who are in follow-up after surgery. The main goal is to evaluate the potential clinical utility of the BladMetrix test by comparing its performance with current follow-up methods, cystoscopy (looking into the bladder with a camera) and urine cytology (examining cells in the urine), using confirmed pathological histology as the reference standard for recurrence (return of disease). Participants will be adults with NMIBC and a positive BladMetrix urine test at the time of their bladder tumor surgery (transurethral resection). After surgery, they will continue their usual follow-up at their local hospital according to national guidelines, including regular cystoscopies and urine cytology. At each planned follow-up visit over about 2 years, they will provide an extra urine sample for BladMetrix testing in addition to their routine examinations. By comparing BladMetrix results with cystoscopy, urine cytology, and histology from any biopsies or tissue from surgery, we will estimate diagnostic accuracy measures such as sensitivity, specificity, negative predictive value, and positive predictive value for detecting bladder cancer recurrence. The goal is to see whether the BladMetrix urine test could safely replace parts of the cystoscopies, help clarify uncertain cystoscopy findings, and support more individualized follow-up schedules for people living with NMIBC.

Hyperthermic Intravesical Chemotherapy (HIVEC) in BCG-Non-Responsive High-Grade NMIBC Patients

This is a Phase II, prospective, single-arm, open-label clinical study evaluating hyperthermic intravesical chemotherapy (HIVEC) with Mitomycin C in patients with high-grade, non-muscle-invasive bladder cancer (NMIBC) who are BCG-non-responsive or BCG-intolerant and are ineligible for, or refuse, radical cystectomy. Mitomycin C is an approved medicinal product used within routine clinical practice and administered with a CE-marked recirculation device (BRS Combat system) that maintains the solution at approximately 43°C for 60 minutes. The treatment schedule consists of 6 weekly induction instillations followed by 9 monthly maintenance instillations. The co-primary objectives are to describe the safety and toxicity profile of HIVEC, including treatment discontinuations due to procedure-related toxicity, and to estimate the 12-month recurrence-free survival (12moRFS). Secondary objectives include characterizing patterns of non-muscle-invasive and muscle-invasive recurrences, bladder cancer-specific survival, overall survival, and quality of life. Approximately 50 patients will be enrolled in this single-center pilot study to generate exploratory safety and efficacy data in this high-risk population and to support the design of future randomized trials
