Radient Pharmaceuticals Announces Preliminary Results From Its Onko-Sure® Clinical Study

TUSTIN, CA--(Marketwire - March 31, 2011) - Radient Pharmaceuticals Corporation (NYSE Amex: RPC), a US-based company specializing in the research, development, and international commercialization of In Vitro Diagnostic cancer tests, announced today preliminary results from its clinical study conducted in collaboration with a well-recognized, large third-party not-for-profit group practice and its affiliates for the validation of RPC's US FDA‐cleared Onko‐Sure® in vitro diagnostic (IVD) cancer test.

The purpose of the study was to determine the effectiveness of Onko-Sure® (DR-70) as a useful tool in the detection of colorectal cancer in all stages of colorectal cancer (CRC), especially early stages where effective diagnosis leads to better patient prognosis. In addition, this study focused on the effectiveness of Onko-Sure®, Carcinoembryonic Antigen (CEA) and the combination of these two tumor markers for additional clinical value. Based on preliminary results, RPC's Onko-Sure® IVD cancer test shows a statistical advantage over CEA in detecting CRC in the early stages of colorectal cancer. Furthermore, when Onko-Sure® was combined with CEA, the sensitivity of the combined test was substantially improved as opposed to using CEA alone. 

RPC plans to disseminate these results in a peer-reviewed journal, either independently or with other third party healthcare organizations. Additionally, RPC plans to present these results to physicians at international oncology conferences and scientific meetings.

RPC's Executive Chairman and CEO Douglas MacLellan commented, "We are pleased by the preliminary findings of the study and anxiously await the final data set analysis. We acknowledge the diligence and hard work that supporting teams have put into the study. Furthermore, we sincerely appreciate the loyalty of our committed staff and shareholders."

The Company also filed an extension today with the SEC to file its annual report on Form 10-K for the year ending December 31, 2010 on or before April 15, 2011, which is the permissible extension date. 

RPC's Onko-Sure® IVD Cancer Test
RPC's Onko‐Sure® IVD cancer test is a simple, non‐invasive 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 detection and treatment monitoring.
