Further Compelling Clinical Evidence Supporting Cxbladder

DIAGNOSTIC OUTPERFORMANCE PUBLISHED IN LEADING CLINICAL JOURNAL

+ Cxbladder providing enhanced diagnostic outcomes not currently available from existing technology.

+ Enables physicians to remove the diagnostic dilemma faced, when existing gold standard tests and procedures are not able to determine a clear diagnostic outcome.

+ Use of Cxbladder minimises the need for patients to have further unnecessary tests and procedures; resulted in 35% less invasive and expensive cystoscopy procedures.

+ Paper published in number one ranked urology journal, European Urology.

+ This real world outcome positions Cxbladder for consideration for inclusion in international guidelines.

Cxbladder’s recent diagnostic outperformance has been published in the number one ranked urology journal, European Urology, adding to Cxbladder’s comprehensive clinical evidence for physicians, reimbursers and healthcare providers alike. Titled “Evaluation of Cxbladder and Adjudication of Atypical Cytology and Equivocal Cystocopy”, the paper validated the performance of Cxbladder in correctly adjudicating all patients diagnosed with urothelial cancer^[1] (UC )among those with atypical cytology and equivocal cystoscopy.

In simple terms, the paper provides compelling evidence further validating the performance of Cxbladder in evaluating patients who have inconclusive diagnosis for UC following cystoscopy and cytology^[2] . Cxbladder delivered 100% accuracy in adjudicating atypical and equivocal diagnostic results enabling physicians to resolve this diagnostic dilemma without the inconvenience and added cost of re-evaluating the patient. Cxbladder also significantly outperformed cytology for accurately identifying patients who do not have UC.  This real world outcome positions Cxbladder for consideration for inclusion in international guidelines.

Approximately 7 million people present with haematuria^[3] every year in the US. While many of these will not have UC, clinical guidelines require investigation to be undertaken, with the existing gold standard procedures being cystoscopy and cytology.

A diagnostic dilemma occurs for physicians and patients when the evaluation of patients, using cystoscopy and cytology, does not give a conclusive diagnostic outcome. This provides a challenge for between 18% and 30% of patients evaluated and for patients returning to the clinic for follow up assessment for recurrence of UC. Currently physicians manage this dilemma by rescheduling and repeating some or all of the tests and procedures, with the consequential increases in costs, invasiveness and potentially poorer patient outcomes.

In the European Urology paper, the use of Cxbladder has been shown to enable physicians to resolve this diagnostic dilemma with 100% accuracy.

The international, real-world study recruited patients from mainstream urology in diverse physician practices in the USA, Australia and New Zealand and included 1,784 patients with haematuria or previously diagnosed with UC.

Key conclusions and outcomes from the study:

(1)   Cxbladder significantly outperformed urine cytology for identifying patients with UC;

(2)   Cxbladder correctly adjudicated atypical cytology and atypical cytology with equivocal cystoscopy in all cases;

(3)   Significant clinical utility can be gained from the inclusion of Cxbladder in the evaluation of patients for UC in both haematuria and monitoring settings, with the outperformance of Cxbladder compared with cytology;

(4)   The use of Cxbladder resulted in 35% of patients avoiding cystoscopies; and

(5)   Cxbladder, either as a reflex to cytology or as a replacement for cytology, would eliminate the diagnostic dilemma associated with atypical cytology results and/or equivocal cystoscopy.

David Darling, Chief Executive Officer of Pacific Edge states that: “The results from this pivotal international study show that the use of Cxbladder in this setting removes the need for cytology and the consequential challenges of atypical diagnostic outcomes, improving the clinical utility for both physicians and patients alike. The resultant outcome is a lowering of the number of invasive tests, procedures and overall healthcare costs.”

Canterbury (New Zealand) urologist Dr Stephen Mark, who is also the President of the Urological Society of Australia and New Zealand (USANZ), the governing body for Australian and New Zealand urologists, says: “The clinical evidence for Cxbladder is compelling, resulting in many of New Zealand’s public healthcare providers adopting Cxbladder into their standard of care. This most recent evidence adds significant extra clinical utility in the diagnostic performance of Cxbladder.

“The addition of Cxbladder into clinical pathways in Canterbury has led to a 30% reduction in patients attending outpatients for a bladder examination, improving the cost effectiveness of our service.”
