The study will be conducted at the University of Minnesota Masonic Cancer Center.

PD-L1 is expressed in multiple cancer types and its status is required to qualify patients for certain immuno-oncology therapeutics. AR expression is prevalent in patients with advanced prostate cancer.

"We are delighted to be working with Dr. Gupta, who is internationally recognized as the principal investigator for several high-impact clinical trials with novel targeted therapeutics and immunotherapy agents for patients with bladder and prostate cancers," said Veena Singh, MD, Biocept's Senior Vice President and Senior Medical Director. 

"Dr. Gupta has been an active speaker at national and international forums discussing the role of novel therapeutics for personalized medicine in prostate cancer." 

Dr. Gupta added, "Tissue sample collection and cystoscopy are the standard methods for detecting bladder and prostate cancers, and these methods are invasive and can be expensive. Biocept's liquid biopsy tests have shown high concordance with tissue biopsies in detecting genetic mutations associated with multiple cancers, and this study is aimed at providing additional clinical support for the use of these tests specifically in bladder and prostate cancers."

Biocept is a molecular diagnostics company with commercialized assays for lung, breast, gastric, colorectal and prostate cancers, and melanoma.  The Company uses its proprietary liquid biopsy technology to provide physicians with information for treating and monitoring patients diagnosed with cancer. 

The Company's patented Target Selector liquid biopsy technology platform captures and analyzes tumor-associated molecular markers in both CTCs and in plasma (ctDNA). 

With thousands of tests performed, the platform has demonstrated the ability to identify cancer mutations and alterations to inform physicians about a patient's disease and therapeutic options.
