A collaboration between University of Birmingham researchers and liquid biopsy cancer detection and screening company Nonacus, has resulted in a test for the non-invasive detection of bladder cancer, which has been launched at the Annual Meeting of the European Association of Urology.

bladder cancer
Called GALEAS Bladder, the urine-based molecular test can quickly and accurately detect bladder cancer and streamline diagnosis, reducing the need for invasive cystoscopies.
It uses highly sensitive liquid biopsy technology developed by Nonacus in conjunction with a panel of biomarkers developed by Professor Rik Bryan and Dr Douglas Ward from the University’s Bladder Cancer Research Centre, to detect the presence of bladder cancer by finding DNA from tumour cells present in the urine.
The researchers validated the biomarker panel was in over 600 patient samples from three UK clinical cohorts, and analyses have confirmed the performance of the test, showing high diagnostic accuracy (sensitivity >90%, specificity >85%) across all grades and stages of bladder cancer.
Professor Rik Bryan said: "Since 2009, Doug Ward and I have been working on various strategies to accurately and reliably detect bladder cancer from a urine sample. The DNA-based genomic approaches that we have been developing over the last eight years, with funding from Cancer Research UK and support and expertise from Nonacus, have allowed us to do just that with a test that appears to rival cystoscopy with regard to sensitivity and specificity for the diagnosis of bladder cancer in patients being investigated for haematuria.
“Our unpublished data also demonstrates that it is possible to use the same mutation panel and Nonacus platform to identify circulating tumour DNA, thus raising the exciting possibility that a single approach can be used throughout the patient pathway.”
The test has the potential to work across the entire bladder cancer patient pathway, reducing the reliance on invasive cystoscopy and expensive imaging for non-muscle-invasive bladder cancer surveillance and minimal residual disease monitoring, as well as triage for haematuria (blood in urine).
Chris Sale, CEO of Nonacus, said: “We are very excited to launch GALEAS Bladder. We are striving to develop a suite of meaningful non-invasive tools that can have real impact on the diagnosis and treatment of patients with suspected cancer. GALEAS Bladder represents the first in this pipeline, helping to improve patients' lives and reducing the burden of cystoscopy on over stretched clinics.”
