BCDx is a urine-based multi-omic/multiplex molecular assay offers a promising solution for detecting cancer recurrence. It is intended for use as a noninvasive method for monitoring for tumor recurrence in conjunction with cystoscopy inpatients previously diagnosed with bladder cancer. This is a, multicenter, prospective, blinded study to evaluate the efficacy (sensitivity and specificity) of a novel multi-omics test for the detection of recurrent NMIBC in patients with a history of bladder cancer undergoing surveillance.
