Pee test could replace scope for bladder cancer checks

Summary
This study is testing a simple urine test called CxBladder to see if it can accurately detect when bladder cancer comes back. Currently, patients need a camera inserted into the bladder (cystoscopy) for monitoring, which is uncomfortable and costly. The study will collect urine samples from 450 people with a history of bladder cancer and compare the test results to standard cystoscopy findings.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- CxBladder Monitor/Monitor+ (urinary biomarker test)
- What this could lead to
- If successful, this urine test could replace some cystoscopies, making bladder cancer monitoring less invasive and more convenient.
- What could go wrong
- This is an observational study, not a treatment trial. The test may not be accurate enough to replace cystoscopy, and results may not apply to all patients.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Low-, intermediate-, and high-risk surveillance subjects with a previous confirmed diagnosis or recurrence of urothelial carcinoma within the last 3 calendar years. 2. Subjects must agree to 4 successive study visits, including urine sample collection at each visit. 3. Physically able to provide a voided urine sample (a sample from catheterization is not eligible). 4. Able to give written informed consent 5. Able and willing to comply with study requirements 6. Aged 18 years or older Exclusion Criteria: 1. Total cystectomy of the bladder, subjects with neo-bladders or illeal conduits 2. Previous muscle invasive bladder tumour (pT2 or greater) 3. Known pregnancy Deferral Criteria 1. Prior genitourinary manipulation (catheterisation, urethral dilation, cystoscopy, etc.) within 14 calendar days of the scheduled urine collection, study enrollment with urine sample collection for Cxbladder Monitor testing should be deferred until a minimum of 14 calendar days has passed since the procedure was performed. 2. Active urinary tract infection (UTI) within 14 calendar days of the scheduled urine collection, study enrollment with urine sample collection for Cxbladder Monitor testing should be deferred until the treatment is complete and the UTI is resolved. 3. If a subject has had intravesical immunotherapy or chemotherapy within the previous 6 weeks, study enrollment with urine sample collection for Cxbladder Monitor testing should be deferred. Study enrollment must be at least 28 calendar days post-last treatment.
