Validation of Cxbladder Triage-Plus for the Detection of Urothelial Carcinoma in Subjects With Microscopic Hematuria (microDRIVE)
Pacific Edge Limited
Summary
It is currently debated whether the use of invasive standard of care procedures, such as cystoscopy, a procedure which involves inserting a thin camera, called a cystoscope, into the bladder to look for signs of disease, is appropriate for patients with microscopic hematuria (blood in the urine that cannot be seen with the naked eye). This is because the risk of disease (bladder cancer - urothelial carcinoma) is relatively low in this population group, approximately 3%. Invasive procedures such as cystoscopy can cause anxiety and pain, in addition to other potential side effects. This has resulted in low admittance for cystoscopy among patients with hematuria (blood in urine) in urology clinics. Therefore, there is a need for a simpler, non-invasive test that can accurately detect the presence or absence of disease (urothelial carcinoma) in patients with microscopic hematuria. Cxbladder, a non-invasive, urine-based test, has the potential to fill this role.
Description
This is a multicenter, observational study prospectively enrolling up to 1000 subjects with microscopic hematuria (three or more red blood cells per high powered field in one urinalysis; no visible blood in the urine) and gross hematuria (visible blood in urine) from US sites. This study will be conducted with subjects with a previous history of microscopic or gross hematuria referred to urology and scheduled for cystoscopy for the investigation of urothelial carcinoma. The study will aim to recruit an equal number of microscopic and gross hematuria patients, controlling the proportion of gros…
