Cxbladder Triage Plus for Hematuria
(CREDIBLE Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to determine if Cxbladder Triage Plus, a non-invasive urine test, can reduce the need for uncomfortable bladder checks (cystoscopies) in individuals with tiny amounts of blood in their urine, a potential sign of bladder cancer. Participants will be divided into two groups: one group will use the test results to decide on the necessity of a cystoscopy, while the other group will follow the usual care without access to the test results. This study targets adults diagnosed with microhematuria (small amounts of blood in urine detected only under a microscope) who can provide a urine sample. As an unphased trial, it offers a unique opportunity to contribute to research that may enhance diagnostic methods for bladder cancer.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. However, if you are currently receiving chemotherapy or have had chemotherapy within the last 6 weeks, you cannot participate in the trial.
What prior data suggests that the Cxbladder Triage Plus test is safe for patients with microhematuria?
Research has shown that Cxbladder Triage Plus is safe and easy for patients to use. It helps assess the risk of bladder cancer in individuals with microscopic amounts of blood in their urine. This test aids in determining whether a cystoscopy (a procedure using a small camera to examine the bladder) is necessary.
One study found that Cxbladder Triage Plus reduced the need for cystoscopies by 59% in patients with low-risk blood in their urine. This allows doctors and patients to make informed decisions without unnecessary procedures. Overall, Cxbladder Triage Plus provides a reliable and safe method for evaluating bladder cancer risk in these cases.12345Why are researchers excited about this trial?
Researchers are excited about Cxbladder Triage Plus because it offers a non-invasive way to help decide whether a cystoscopy, a procedure involving a camera to look inside the bladder, is necessary for patients with hematuria (blood in the urine). Unlike the standard approach that relies on direct visualization with cystoscopy, Cxbladder Triage Plus uses advanced urine testing to provide crucial information without the need for invasive procedures. This method could potentially reduce the number of unnecessary cystoscopies, making the diagnostic process safer and more comfortable for patients.
What evidence suggests that Cxbladder Triage Plus is effective for reducing cystoscopies in microhematuria patients?
Research has shown that Cxbladder Triage Plus can assess the likelihood of bladder cancer in patients with microhematuria, which refers to tiny amounts of blood in the urine visible only under a microscope. In this trial, participants in the Test Arm will receive the Cxbladder Detect+ result. The urologist study investigator will discuss this result with the participant to decide whether to proceed with cystoscopy. Studies indicate that this test can safely reduce the need for cystoscopies by 70-80%. It has a predicted sensitivity of 93.6% and specificity of 90.8%, making it both accurate and reliable in identifying potential cancer cases. Since 95-97% of patients with microhematuria do not have cancer, using this test can help most people avoid unnecessary procedures.12367

Are You a Good Fit for This Trial?
Adults aged 18 to 88 with invisible blood in their urine, confirmed by a lab test within the last 90 days. They must be able to provide a urine sample and understand English or Spanish (with an interpreter if needed). Participants should be willing to follow study procedures and give informed consent.Inclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Initial Assessment
Participants provide a urine sample for the Cxbladder Triage Plus test and are randomly assigned to test or control groups
Decision Phase
Urologists and patients decide on cystoscopy based on Triage Plus results or standard care
Follow-up
Participants are monitored for persistent hematuria and other outcomes
What Are the Treatments Tested in This Trial?

Trial Overview
The trial is testing whether using 'Cxbladder Triage Plus,' a genetic urine test for bladder cancer, can reduce the number of cystoscopies needed. Patients are randomly assigned to either get this new test result before deciding on cystoscopy or follow standard care without the test result.
How Is the Trial Designed?

Treatment groups
Experimental Treatment
Active Control
The site will receive the Cxbladder Detect+ result and the urologist study investigator discuss it with the patient before making a shared decision whether or not to proceed with cystoscopy.
Neither the site nor the patient will receive the Cxbladder Detect+ result. The decision whether or not to proceed with cystoscopy will be made following standard of care.
