TUSTIN, CA--(Marketwire - March 17, 2011) - Radient Pharmaceuticals Corporation ("RPC") (NYSE Amex: [ RPC ]) announced today it has retained law firm DLA Piper to represent the Company in a class action suit filed 2011 by The Rosen Law Firm, P.A. on March 11, alleging RPC has violated federal securities laws by misrepresenting the relationship of RPC with third parties in the Company's clinical studies of its Onko-Sure® in vitro diagnostic cancer test. The Company has been fully transparent in its relationship with third parties not only in its press releases but also by having attached the actual agreement defining the precise nature of that relationship in its public filings. Any claims to the contrary are meritless. DLA Piper will be defending the Company in the above suit.

The Company stated there is no basis to the suit filed by The Rosen Law Firm and it intends to vigorously defend against the class action suit. Furthermore, it intends to seek action against various parties who have spread false, misleading and malicious rumors against Radient Pharmaceuticals, its business, and business practices.

Radient Pharmaceuticals Executive Chairman and CEO Douglas MacLellan commented, "RPC is determined to create and protect shareholder value and we have tasked DLA Piper's counsel to aggressively explore every option available to the Company in response to the above mentioned situations. We remain confident in the Company and believe RPC is in a solid position to build and grow the business on behalf of loyal shareholders."
