STRATA: Safe Testing of Risk for AsymptomaTic MicrohematuriA
- Conditions
- HematuriaUrothelial Carcinoma
- Registration Number
- NCT03988309
- Lead Sponsor
- Pacific Edge Limited
- Brief Summary
To evaluate the clinical utility associated with the integration of Cxbladder into the evaluation of subjects presenting with hematuria for evaluation of urothelial carcinoma (UC) without compromising detection of UC.
- Detailed Description
Randomised two arm pragmatic clinical study to be conducted at multiple sites in US and Canada. The trial will recruit hematuria subjects, presenting to qualified sites (academic, community), who are being evaluated for urothelial carcinoma (UC). Up to 100 consecutive eligible subjects will be recruited per site.
Recruitment & Eligibility
- Status
- COMPLETED
- Sex
- All
- Target Recruitment
- 554
- Patient is undergoing investigation of recent confirmed hematuria, as defined by the AUA/SUFU Guideline (Barocas DA, Boorjian SA, Alvarez RD et al. Microhematuria: AUA/SUFU guideline, J Urol 2020; 204:778) (by either flexible or rigid cystoscopy/TURBT), including hematuria subjects referred due to suspicious/positive imaging, in order to determine the presence of urothelial carcinoma.
- Able to provide a voided urine sample of the required minimum volume
- Able to give written consent
- Able and willing to comply with study requirements
- Aged 18 years or older
Exclusion Criteria
- Prior history of bladder malignancy or pelvic radiotherapy. Prior history prostate or renal cell carcinoma within the last 5 years.
- Prior genitourinary manipulation (flexible or rigid cystoscopy / catheterisation, urethral dilation) in the 14 days before urine collection,
- Known current pregnancy

- Primary Outcome Measures
Name Time Method To measure the change in cystoscopy procedure use count between control and test arms when Cxbladder Triage is used in the evaluation The outcome measure will be assessed by 6 months after trial completion. To evaluate the increase in utility as defined by the reduction in cystoscopy procedure count when Cxbladder is used in the evaluation. The comparison will be made when comparing test and control arms on a per subject basis. The gold standard for determination of a confirmed clinical diagnosis is cystoscopy confirmed by pathology, plus imaging or any follow-up investigations relating to the visit.
- Secondary Outcome Measures
Name Time Method To measure the number of subjects who were incorrectly diagnosed associated with the integration of Cxbladder into the evaluation of subjects (or sub-cohorts on test and control arms) presenting with hematuria for evaluation of UC The outcome measure will be assessed by 6 months after trial completion. To quantify the false negative rate (the percentage of the negative fraction incorrectly diagnosed) associated with the integration of Cxbladder into the evaluation of subjects (or sub-cohorts on test and control arms) presenting with hematuria for evaluation of UC
Quantify performance characteristics of Cxbladder signatures including for the detection of high grade/stage UC. The outcome measure will be assessed by 6 months after trial completion. The Cxbladder signature test results will be compared to that of cystoscopy, which is the gold standard method for diagnosing urothelial cancer; the true positive and true negative rates will be measured, along with the false positive and false negative rates of the test. The results will be reported as sensitivity, specificity, positive and negative predictive value of the Cxbladder signature tests for detecting urothelial cancer in patients referred for evaluation of hematuria.
To clinically validate the performance characteristics and test negative rate of the Cxbladder Detect+ test. The outcome measure will be assessed by 6 months after trial completion. The Cxbladder Detect+ test results will be compared to that of cystoscopy, which is the gold standard method for diagnosing urothelial cancer; the true positive and true negative rates will be measured, along with the false positive and false negative rates of the test. The results will be reported as sensitivity, specificity, positive and negative predictive value and test negative rate of the Cxbladder Detect+ test for detecting urothelial cancer in patients referred for evaluation of hematuria.
To measure the change in total procedure use (and the invasive procedure sub-group) count between control and test arms when Cxbladder is used in the evaluation. The outcome measure will be assessed by 6 months after trial completion. To evaluate the increase in utility as defined by the reduction in total procedures (and the invasive procedures subgroup) count when Cxbladder is used in the evaluation. The comparison will be made when comparing test and control arms on a per subject basis.
