BioTime unit expands clinical development of bladder cancer test BioTime and its subsidiary OncoCyte announced that OncoCyte has expanded the clinical development of its urine-based bladder cancer diagnostic test by initiating a multi-site clinical trial. The trial, which will involve up to 1,200 patient samples obtained from at least four large urology clinics located throughout the U.S., has received Institutional Review Board approval at multiple sites and should begin enrolling patients within the next week. OncoCyte’s initial clinical study of its bladder cancer diagnostic test began in January and involves pathology specimens being collected at a leading medical institution with an international reputation for excellence and discovery. The multi-site clinical trial is designed to expand the potential use of the PanC-Dx bladder cancer test beyond pathology laboratories and into urologic practices at the point of cystoscopy. Cystoscopy along with urine cytopathology, are the standard methods utilized for bladder cancer screening and diagnosis. The multi-site clinical trial should be completed within 12 months. The goal of the current clinical trial is to compare the performance of OncoCyte’s proprietary PanC-Dx bladder cancer markers to the performance of cystoscopy.
