Radient Pharmaceuticals Resumes Collaboration to Advance Its Onko-Sure® In Vitro Diagnostic Cancer Test in the USA

TUSTIN, CA--(Marketwire - August 31, 2010) -  Radient Pharmaceuticals Corporation (RPC) (NYSE Amex: RPC) announced today it has resumed collaborations with Mayo Collaborative Services, Inc. to conduct a clinical study for the validation of RPC's US FDA-approved Onko-Sure® in vitro diagnostic (IVD) cancer test as a useful tool in colorectal cancer (CRC) recurrence and treatment monitoring.

Over 1,000 colorectal patient samples with various disease stages will be tested in parallel by RPC and Mayo Clinic to directly compare the results of the Onko-Sure® test with the Carcinoembryonic Antigen (CEA) test. The primary goal of the study is to determine whether Onko-Sure® is more effective than CEA at detecting early stage colorectal cancers. CEA has been reported to misdiagnose a disproportionate number of early stage cancers. Detecting cancer in earlier stages can lead to improved accuracy in the treatment, monitoring and recurrence monitoring of the disease in cancer patients. This head-to-head study is scheduled to be completed in the fourth quarter FY2010 and data generated will be provided to Mayo physicians and investigators for publication in medical journals.

"We are very excited to resume collaboration with Mayo's Validation Support Services team. This marks a critical and potentially market changing milestone for Radient Pharmaceuticals and for our Onko-Sure® IVD cancer test," commented Douglas MacLellan, Chairman and CEO of RPC. "Through this work, we expect to validate the efficacy of RPC's Onko-Sure® test as a critical tool for treatment, monitoring, and/or recurrence monitoring of colorectal cancer suffers."

RPC's Onko-Sure® IVD cancer test is a simple, non-invasive, patent-pending and regulatory-approved in vitro diagnostic (IVD) test used for the detection and monitoring of the treatment and/or recurrence of various types of cancer. The test enables physicians and healthcare professionals to effectively detect and/or monitor certain types of cancers by measuring the accumulation of Fibrin and Fibrinogen Degradation Products (FDP) in the blood. FDP levels rise dramatically with the progression of cancer. Onko-Sure® is cleared by the US FDA for detection during colorectal cancer treatment and/or for recurrence monitoring in colorectal cancer patients and by Health Canada for the detection, treatment and/or recurrence monitoring of lung cancer.
